Green Improve Ltd installs insulation, heating, ventilation and solar panels, mostly under government schemes. Many reviewers report friendly, tidy teams and work completed quickly, often naming Theo, Alex and Scott for ventilation, cavity wall insulation and electrics. A few describe serious problems: one says they were left with open wires, no ceiling and no heating for five months, with broken belongings and no compensation, another reports missing paperwork a year on that leaves them unable to service the system or set the heating, one says damage was covered up and plumbing boarded over, and another says calls back were never returned.
Good and bad and overall I can't recommend the company to carry out govt grant work. I'd say a couple of bad apples spoilt what was otherwise a quick install. FIVE insulation lads lined my outside facing walls in a week, 4" thick and plastered. SIX plumbers fitted a complete heating and hot water system in 2 and a half days!! Couple of problems, in all fairness the boss compensated me for.. Bit of damage that the lads tried to cover up. A backup lad insisted in boarding right across our utility room and covered all the plumbing, even promised but failed to provide photos so I could find all the burried pipes. I had to chop out the boarding as a result. Sadly a bag of new holiday clothing is now missing, 50% our fault for leaving it in the middle of the chaos despite me telling the Mrs to move it! Over a year on and the absence of any and all paperwork means I have no way of recording the annual servicing and no instructions allowing me to set the on/off avoiding peak times. My bills are so big I've turned the lot off!
Such a poor experience with this company. Been awaiting a call back for over a week, have chased 4x times as no-one has been getting back to me. Keep getting told someone will call back the same day, but they still haven't. Will be giving up and finding another company to do the work.
Team worked hard & long but left me with open wires hanging, no ceiling, no heating that I am still without for 5 months. My full freezer unplugged, broken Henry vac, broken mirror, fittings & blinds for both lounge windows gone. I think you get my experience of Green Improve!! Complained many times, was in bed to keep warm, Christmas & months before & after freezing, nothing in compensation or response from them, extremely dissatisfied will be getting legal advice. Taking Chemo to top this!!
Theo did a great job at my property, installing extractor fans in my kitchen and bathroom. He was friendly, informative and considerate. I would highly recommend this company.
We recently moved into our house and we decided to opt into the government scheme for cavity wall insulation and improved ventilation. We would highly recommend Green Improve and the whole team were a delight to work with. The survey was arranged quickly and at a time and date that suited us. The surveyor was polite, thorough and he explained everything that was involved in the installation. Alex did the cavity wall insulation and Theo did the vents and window ventilation. We knew this was a messy job having installed an extractor fan at our previous house but both Alex and Theo were amazing. They cleaned up after the work, they were so friendly and polite it was a pleasure having them at our house. I have a 15 year old dog who is terrified of strangers and Theo was fantastic with her. My husband is an electrician so Theo was under the spot light and he did an amazing job! 100% trustworthy and professional company. I will be contacting my local Labour MP to sing the praises of Green Improve!
Have an excellent service for my cavity wall insulation and vents fitted. The work completed by Theo and Alex and all mess cleaned up
Hopefully, the services they provide is better than them blocking my drive for hours, with none of my neighbours having any idea whose house they are at to remove the van.
Team was very professional, service was smooth from start & sending mail to my address, contacting them then arrange survey& installing insulation& fan all done within a week, the whole team was very lovely, cooperative & highly professional, special thanks to Teo who installed the fan & ventilation for windows, Can' t thank the whole team enough for their hard work but you really are life changer & i wish you get the credit you deserve for all your sincere efforts
Theo had fitted our ventilation great service cleaned up afterwards and knowledgeable very happy with workmanship Alison
Efficient, helpful team who were able to work around my schedule and get the cavity insulation and ventilation installed to a high standard
Absolutely superb service from start to finish. The work was executed extremely quickly, and was tailor made to the household needs. I could not recommend the service Green Improve (and their affiliates) offer, highly enough. I will also be using their aftercare services to keep on top of servicing etc., going forward.... Excellent. xxxx
The team did fantastic work for our old house. Everything was done with high level of professionally and very quickly. Insulation, gas boiler and radiators installed and we are living in warm comfort now. We wish everyone the same warm Christmas as us now in our renewed house.
Honestly amazing time not stressful what so ever the guys Matt, John, mic, theo n others where so friendly and worked with efficiency n communicated about what they where doing and where very polite when I asked questions :3 would reccomend
Really excellent and speedy survey and installation of cavity wall insulation through the GBIS scheme. I got referred to them by Octopus after the initial installer failed to provide an installation date after 4 months. In contrast, Green Improve completed both their survey and install within 5 weeks of the referral. Only downside is that they don’t allow private funding – they only do work through the government schemes. Otherwise, great people and great quality of work and service.
Very professional work done, excellent job done. The guys were friendly, considerate and cleaned after themselves. Well done Scott, Mick, Theo, Alex, and plumber Jordan
Had Chris working in my house today excellent work left everything nice and tidy very happy thanks

So pleased with Lee' s installation and workmanship, explained all aspects of the process, kept to the work on time . Very tidy and minimal disruption. I would 100% recommend these Thankyou again
I had insulation and storage heaters installed in my property the work men that came along insulation team mark and his team and electricians Scott and Ben all the lads were very polite and well mannered the work they did was to a high standard and would definitely recommend
I would just like to say I very big thank you to Theo for improving my home with fitted ventilation he really did an amazing job no mess no fuss left me home lovely and clean ☺️
Just had Theo at my property to install ventilation after my cavity insulation was done, he did an brilliant job kept my property clean and tidy. Thank you
Excellent service. Did the job brilliantly without little disruption. Great work from Theo and Alex
Garry and his mates, Big Matt and his heat pump mates Little Matt and Mike, Ben the electician and his mate Chris, Gavin and his panel mates, excellent workmen excellent men to have in my house. These men knew what they were doing and woked hard and never wasting a minute and their maners were impeccable.
Scot did a nice tidy Job on the install. Polite and friendly would happily use again.
Thank you so much to the full team at green improve. From the plasterers Leon and Graeme who were very friendly and worked really hard to get the job done. Theo the electrician who talked me through everything he was doing, advice and made it look easy to control the heating. Excellent job. And the plumber (whose name I didn’t catch) quickly finished off the job with ease. Overall I am really impressed with the well planned organisation of this company and the caring nature of all their employees. I would definitely recommend to anyone who needs their services. Thank you, Hollie x
Scott and Theo came and installed our extractor fan core vents and trickle vents. Arrived early and on time and talked us through it all and did the job quickly and tidily. Great process from start to finish.
Green Improve did a fantastic job by helping me to get grant funding for an air source heat pump and solar panels. My house had an E grade EPC, and as I was on a small salary, they helped me liaise with the council and contractos so that I was able to get the job done with minimum fuss. Many thanks
Theo and Scott come to do the fan and air vent insulation at our property… they were very efficient and did a brilliant job, kept the work areas clean and tidy and left everything as found. Would definitely recommend! Thanks guys 🙂
I have recently had cavity wall insulation and ventilation work carried out under the government scheme. Alex completed my insulation and Theo carried out the ventilation works. I could arrange the time to suit my diary/life which was a positive. Theo was brilliant, very tidy when drilling holes for vents in the external brick work. Alex was quick and efficient. Both jobs done on different days and they were done in a couple of hours. Pleased with the work. The fans are abit noisy but Theos explained how they can be adjusted to suit and left us the information to do this. I would recommend this company.
Theo carried out work on my property, installing ventilation fans within the bathroom and kitchen as well as window vents. Did a great job and was considerate of my home, cleaning up on the go and consulting me before carrying out work. Arrived at time he said he would and overall happy with his work.
It’s a 5 star review for Green Improve. A fantastic company with efficient, knowledgable and friendly office staff. The cavity wall and roof insulation was all done in one day. The central heating installers were a great team , lovely friendly lads, very helpful, good at their trade and cleaned up after themselves each day. I am extremely happy with the results. Thank you to everyone involved at Green Improvr.
A big thank you to Theo & Alex for the work they completed today. They did cavity wall insulation, trickle vents on all the windows and vents in the kitchen and bathroom. Although the work took a little longer than expected thanks to the nori brick they did a brilliant job and cleaned up so well you could hardly tell they had been here. Very professional and friendly. I would definitely recommend the company to anyone thinking of using them.
Theo & Chris arrived to install new heating in my property, they worked really hard, clean and tidy, a pleasure to have around the property, couldn't recommend enough
What a team Gary and Anton are. Great job today insulating my loft and the cleanest workers ever. Thank you both so much. Also thanks to the girls in the office, Donald the surveyor, Alex who did my cavity wall insulation and Fyn and team who did the boiler and everything else. A great job. Thank you all once again.
We recently had a range of home improvements completed through Green Improve under the ECO4 scheme, and we couldn’t be more grateful for the experience. From start to finish, the entire process was handled with professionalism, care, and real efficiency. A huge thank you to Carrie, who managed everything so smoothly. She was supportive, knowledgeable, and always on hand to answer questions, making what could have been a daunting process feel easy and well-organised. Once approved, the work was carried out quickly and to a very high standard by several fantastic teams. Danny, Graham, and Leon did a brilliant job installing the insulation — friendly, respectful, and clearly experienced. Mikey and Scott installed the vents and heaters with real attention to detail, and although we didn’t catch their names, the team who fitted the solar panels were excellent — fast, efficient, and knew exactly what they were doing. Every person from Green Improve who came to our home was a credit to the company — courteous, punctual, and focused. It was clear that each team took pride in their work. We honestly can’t thank you all enough. Last winter was incredibly expensive and difficult for us, but the improvements you’ve made will genuinely transform our home life and give us peace of mind going into the colder months. Green Improve, thank you for everything — your work has made a real difference.
Very efficient and helpful. Would use again, if the need arose.
Fast work friendly people worked fast very good job
Great job done by Chris and Theo today with my new ventilation and trickle vents, very clean tidy good job and house is cleaned and perfect after they had finished, thanks very much.
Cannot fault Green Improve. I had airsource heat pump, new radiators and solar panels fitted. They were quick, tidy and left a tidy job. They worked round me and 2 kids in the house. 2 plumbers James and Sam were the main workers in the house who were very trust worthy workers and left them in house while I popped out. Everything was fully explained and 3 months later still very happy with the work. The electricians also brilliant Chris and Theo came back to fix a fault I had with not being able to access the control panels but they arrived withing a day or 2 of me calling. 5 star service and would 100% recommend. Would have then back to do annual service of they offer this I was that happy with their work!
A great team!!!! We have had cavity walls insulation, trickle vents and bathroom and kitchen vents fitted. Theo arrived this morning, ran through all the works checked at each stage of install and on completion and kept everything clean and tidy. A really great job!!! Thank you
Very impressed with the work and workmanship from John and his team Sam and the apprentice Tommy. Very happy with the work carried out.
Green Improve installed brand new heating throughout my property, we had Chris Theo & Mick they did an excellent job. Very tidy and neat work would definitely recommend
Simple process from start to finish excellent communication throughout would highly recommend
Recently had a new heating system installed by Green Improve. Amazing service from start to finish and special thanks to Caroline and Shannon
Had cavity wall insulation and vents installed by the team. Scott, Alex and Lee did a great job sorting the extractor fans and the cavity wall out, and are top blokes too! A good job done professionally and quickly, with good communication at every step.
Friendly and helpful service. Made sure the job was done despite cold weather making it impossible to complete the cavity wall insulation on the original date.
Have complained about high running costs and not functioning since it was fitted in June. They say it's user error. Asked Grant to check system turns out heat pump too small for house and installation errors. Pipe fell off heat pump when engineer inspected it. Waiting for Trustmark inspection as this Company don't care once they have been paid.
Green Improve recently finished a two week job of interior wall insulation and first-time central heating installation as part of the ECO4 scheme. They did a great job working around me, my wife, and three children in the property, which is an old Victorian terraced house. Liam, Danny, and Graham did the insulation and plastering; James and Sam did the heating insulation; and Chris finished off with the electrics. They were all pleasant and helpful, and they came up with very sensible solutions for our old house. They were all extremely hard working and did a good job; they also cleared up well after they finished. Highly recommended. Thanks, Nathan.
We’ve had a great experience with Green improve, Matt ,Matt and Mick have been amazing, they have worked extremely hard to get the job done, they are all professional hard working members of the team. We have had trouble with another company in the same line of work in the past, but these guys have restored are faith. We couldn’t be happier with what they have done, I highly recommend 😊
After a previous very bad experience with another Eco grant company we were initially worried about the work being done but I'm so glad I did.Matt, Matt and Mick for Green Improve, were amazing, they explain everything every step of the way and went the extra mile to ensure we were happy with all aspects of the the work. I can't say enough about how professional and accommodating they were. Hopefully your lucky enough to have these chap work on your house. Very happy customer Tristan and Katy
A great company, and the home insulation they fitted has made such a difference.
From start to finish they were very helpful explained everything very friendly always to having the work done which they turned upon time did not make a mess very friendly I'm very helpful explained everything would highly recommend hope to deal with you again in the future thank you so much
Fantastic from start to end. At first seemed too good to be true but the outcome has been a game changer. Customer experience was spot on over the phone and in person. Was all legit through British Gas.
Wonderful service, all works carried out during on-going tenancy yet was conducted in a professional manner with minimal disruption to the tenant and her family. 5* thank you
We had an Air source heat pump and ventilation fitted, the tradesmen are a credit to the company. James and Sam carried out the plumbing work and we're followed by Scott and Brett to do the electrical work. Thank you green improve for going above and beyond.
Had Cavity Wall Insulation and Loft Insulation installed by the Green Improve team and I can’t recommend them highly enough. From the initial consultation to the final installation, the entire process was smooth and stress-free. Super friendly office staff, always available to answer any questions we had. The chap that did the Insulation was also very nice and super professional. The difference this installation has made to our home is amazing, we're so much warmer and don't have to put the heating on for long anymore. Would definitely recommend and use again.
I would highly recommend Green Improve Ltd. John and Tommy were the heating engineers, and Mick the electrician. They were a great team - professional, polite, friendly, hard working and good company. I can't rate them highly enough. They installed an air source heat pump and new radiators for me, and put everything back afterwards. Thank you so much to you all. You deserve a big bonus and a new van 😁
I have recently had a boiler upgrade and loft insulation fitted by green improve, the work was carried out to a high standard, the office staff were really helpful, Frankie in particular provided excellent guidance and the install team were great
Fantastic service from the team at green improve - great job and brilliant communication throughout! Highly recommend!
Green Improve installed cavity wall insulation and an air source heat pump at my property. The team was professional, courteous, and delivered work of an exceptional standard. The entire process was seamless from start to finish. Their communication and aftercare have been fantastic—they arrived exactly when they said they would and completed the work on time. I highly recommend Green Improve to anyone looking for heating and insulation upgrades.
We recently had internal wall insulation installed by Green Improve, and it has completely transformed our home. Not only have we noticed a significant reduction in our energy bills, but the overall comfort of our living space has improved dramatically. It’s amazing to feel the difference each day. The entire process was seamless. From the friendly and professional office staff to the efficient engineers, everyone was a pleasure to deal with. They took care of everything from start to finish, making the installation quick, stress-free, and hassle-free. The team was in and out before I knew it, leaving behind excellent results. If you’re looking to save on energy bills and enjoy a more comfortable home, I can’t recommend Green Improve enough. Their expertise, smooth service, and commitment to customer satisfaction are second to none. Take the step towards an energy-efficient home with them—you won’t regret it!
I can not thank the team enough for the top job they did on my home. They installed cavity wall and loft insulation for me (even doing a good job of matching the paint colour) air source heating and solar panels through the Government ECO4 scheme. Everything was done in a few days with little fuss. And when the team did need to move furniture etc they were incredibly professional and tidy. I have nothing bad to say on the before, during or aftercare they have provided. I can not recommend highly enough!
We have just done Cavity Walls Insulation on our detached property. Alex was excellent. Also Theo and Brett did the kitchen ventilation fan extractor. Professional and 5 star service. The admin staff Poppy was very helpful making the appointments for the whole process. Thank you the team of 'Green Improve'. All the best. Yakub Patel. Preston. Lancs.
I really appreciate the communication from Poppy and how quickly I was able to schedule the jobs at my place. Alex did a great job with the cavity wall insulation, while electricians Scott and Teo worked on improving the extractor fans in my kitchen and bathroom. Scott also installed a core vent in the living room and six trickle vents in three bedrooms. I could see that all of them genuinely cared about their work. Alex spent a couple of hours patiently working and made an effort to clean up the dust, and while the windows got a little dusty with the orange dust, it was easy to clean the next day. Scott and Teo worked hard to keep the job tidy and ensure everything was done to a high standard without making unnecessary cuts in the walls for the cables. Poppy was incredibly organized and explained all the details thoroughly. Overall, it was a wonderful experience and I’m really happy with the work done!
Green Improve Review We recently engaged Green Improve after our central heating boiler failed, of course just as the weather turned colder and Christmas was looming.. We found them to be extremely responsive and as we are now in our eighties they very quickly sourced an appropriate boiler and assisted with improving our insulation on the house. We cannot speak highly enough of the whole team at Green Improve who communicated well throughout the whole process, keeping us informed of progress. They were friendly, kind and made every effort to get the job done quickly. It is appropriate to name the team with whom we had dealings because without exception every one of them worked so hard to ensure a quick solution for us. They are Tom, Tony, Matt and another Matt plus John, Holly, Poppy and Beth and not forgetting Alex. We are very grateful to them all for all of their efforts on our behalf. There are a couple of finishing off jobs still to be done post Christmas but we have every confidence that these will be completed in a timely fashion.
We had Theo, John, Sam and Jay that have installed central heating into the property in just a few days. They were all very hard working and friendly. We have a very energetic dog that's excitable and they kindly worked around him without fuss. We were informed about each stage of the work and given a walk-through of the boiler and thermostat including the smart app. I'd definitely recommend Green Improve!
Matt, Matt & Chris were a great team fitting my elderly grandmother's combi boiler for her - they made it as stress free for her as possible. Very friendly and SO hardworking. Thanks guys!
Just had my external walls and loft insulation installed and WOW what an amazing team from start to finish.Neil,Hayden and Myles from Green Improve were so professional, polite , tidy and their work is immaculate and at a very high standard .
Fantastic job by the team. Boss Matt, Jnr Matt, James and Chris. Couldn't ask for a better crew smashing through the house and leaving it spotless, and warm!!!! Highly recommended! Painless from start to finish.
The Insulation team were fabulous! Arran, Graham & Carl were brilliant with my father explaining all that needed to be done. They were efficient, professional and just got the job done! Did an amazing job can’t thank them enough. They were swiftly followed by the heating team Matt, Matt and Michael, who were absolutely brilliant from start to finish, tidying up every night to not disturb my 94 year old father. The job was then handed over with a detailed explanation of how everything works and how to best use my new heating system and solar panels. I would highly recommend using Green Improve to anyone thinking of getting the grant.
Green improve is an excellent company reliable and fast service. Scott and Theo did an excellent job. The quality of work was top-notch, and the windows now feel much more energy-efficient. The boys even hoovered after themselves . I would highly recommend their services to anyone looking for professional and reliable builders. Even the office staff Poppy stayed in touch when the work was getting carried out . One happy customer.
Amazing service from the 3 guys!! Warren Aaron and graham! Very friendly, quick hard working and cleaned up after! Thank you very much! 😀
aweful
Neil and team have been fantastic. Hard working and clean and tidy. Nothing was too much trouble. I would highly recommend them
Very happy with the whole experience from this company from the very beginning. Staff on the phones or what's app we're friendly and very helpful. Staff that came out to the job were very respectful and polite and got the work done as quickly as possible leaving no mess behind. Would definitely recommend.
Over the last 5 years or so, we have been told repeatedly, that we are eligible for First Time Central Heating. I'm disabled, with multiple health conditions, and had Breast Cancer 4 years ago. My Husband isn't in good health, either, but struggles to keep working. We had been let down, previously, by 3 or 4 different companies over the Central Heating, and were losing hope of it ever getting done. We have lived in our home for 32 years. The house was built in 1904 - 120 years ago. Neither the house, or us, had ever had Central Heating before. A couple of weeks ago, I got a call from Green Improve, and I couldn't believe how helpful they were, at every stage of the process. We were so shocked when they told us how quickly they could fit the Central Heating for us. The entire process, from the first contact to completion was only TWO WEEKS! The 2 young men that installed our system, James and Sam, were absolutely amazing. They got on with the job with no fuss, they tidied up after themselves, and went out of their way to fit everything in accordance with our needs, they were helpful, polite and professional. I've been so impressed by the company, and especially James and Sam, that I'm hoping to have them overhaul my 81 year old Mother's Central Heating system. I have already spoken with their boss, this morning about it. Even if my Mother doesn't qualify for a grant, as we did, it would still be worth her paying to have this company do the work that needs doing. Overall, it's been the best experience we've had of tradesman working in our house. Seriously, I can't fault Green Improve, and would like to say a big "Thank you" to everyone at Green Improve, especially James and Sam.
Just had Matt and Matt from Green Improve install my air pump and heating, they are both really nice guys and have done a great job. Really happy with all they have done.
Matt and Sam have been fantastic throughout. Very respectful of the property and a delight to have in the house!
Had Theo,mick James,John here this week . Was very pleased with the work they have done ,very helpful clean works and explained how things work. Good bunch of lads. Thank you x
Extremely professional. Great , quick installation. No mess, or fuss
A very Professional well run company. Easy transparent process throughout from start to finish.
I could not recommend this team highly enough. Matt, Matt, Mick and Theo have been fantastic fitting our new heating system and loft insulation. They are such hard workers, polite and respectful. I was worried about having this work done in ky home with young children however they made it a great positive experience. I was so impressed with their high standard of work and can not thank them all enough for their fantastic service
Matt, matt and mick were absolutely outstanding. Very professional. Talked us through everything that was being done. Very clean and trustworthy in our home. Would highly recommend. Went above and beyond our expectations.
Great company, Theo, Chris, Dan & James have been brilliant this week. Explained everything to me, worked efficiently and tidied up after themselves. Would highly recommend
Matt, Matt, Mick and Chris have been professional from start to finish. They worked hard, focussed, and didn't sit around drinking tea like the PH Tips chimps. They've accommodated my house clearing as they've gone along, cleared up, been excellent company, discussed the options when needed, explained the system clearly, completely trustworthy and I'd really recommend them to anyone getting any work done by them.
I recently had work done through this company and they were great from start to finish. They were organised and professional and the work was completed to a very high standard.
Had a great experience with this company. The process was extremely fast from start to finish and the staff are very nice and knowledgeable. Very happy with the works done on my property
