OffGrid Plumbing and Heating has a lot of happy customers in Falmouth who describe the firm as professional, friendly and reliable, with polite and helpful staff. Reviewers say Josh and his team turn up when they say they will and explain the work clearly, and several mention the tidiness of the job and the clean finish. People report boilers fixed or fitted, showers and bathrooms replaced, solar panels installed and oil boilers serviced. Some reviewers describe the firm as a real problem-solver when another company had failed. One reviewer complained they were given wrong advice. The most recent reviewer praised Josh by name for being there when he said he would and for doing the job well.
From the very beginning when I contacted Josh from Off Grid Heating and Plumbing to ask for a quote, to the time he completed the installation of our new condensing boiler for our Methodist Church...he was always very reliable and always there when he said he would be, and very professional in his work and attitude. He was very efficient with his admin and always returned my calls if I left him a message or emailed him with a query. I would have no hesitation in recommending Josh to family and friends to carry out a job whether large or small. Good job, thank you..well done Josh!
Professional, efficient and excellent customer service. Hard working, respectful to the property and friendly. Highly recommend.
Brilliant reliable friendly honest company Found my problem sorted it staight away So véy happy to find off grid definitely reccomend very happy with invoice and further advice Wish your company all the very best Karen Henshaw
After four previous visits from different gas engineers who failed to find and fix my gas fire problem, Josh arrived when he said he would and within an hour the fire was working as it should and still is. I recommend Off Grid without reservation. Polite, friendly and efficient service.
A prompt response and good job done by Josh
Very quick at coming out on the same day as the initial call and repairing a burst pipe on our boiler, also have helped out in the past with a shower replacement and annual boiler service. They are friendly and reliable and I would highly recommend.
Josh and all the guys at Off Grid are fantastic. One real point to note is their punctuality and date planning - it makes all the difference when planning work on your home. We had some challenges with the delivery of parts and Josh stayed patient and calm all the way through our most recent job. They have sorted Solar panels for us, a new solar set up along side more regular plumbing like taps and leaks. I can't recommend enough.
Prompt, reliable service. Good advice
Josh is always very polite and does a brilliant job servicing our boiler and giving his advice. I would highly recommend his business for it's service.
We can't thank Josh at Off Grid Plumbing & Heating enough for the outstanding service he provided. When our boiler suddenly stopped working on a Sunday evening, Josh found the time to come out to our house at very short notice to investigate the problem. That level of commitment and customer care is incredibly rare and was hugely appreciated. This is actually the third time we've used Off Grid Plumbing & Heating, having previously called on them for a couple of smaller plumbing jobs. Every experience has been excellent. Josh is always professional, friendly, reliable, and takes the time to explain everything clearly. His approachable manner and genuine willingness to help are a breath of fresh air compared to what we've experienced with many other plumbing companies. I genuinely couldn't recommend Off Grid Plumbing & Heating more highly. They've earned our complete trust and will definitely be our go-to plumber for any future plumbing or heating needs. Thank you, Josh, for your exceptional service once again!
Fabulous service. Knowledgeable, friendly, polite and efficient staff. Highly recommended and will use again.
A hidden gem I can’t sing these guys praises enough from fitting me a shower also plumbing and pipe work done and on next call came out of hours to help with no hot water fixed the boiler all within the hour and put right a job previously bodged by Mitchell and Webber fantastic service excellent workmanship Josh and Matt were both lovely men and were very knowledgable 10/10 if I could give more I would
I highly recommend Off Grid Plumbing & Heating. They recently installed our new oil boiler, and from start to finish the service was outstanding. The team were professional, punctual, and worked to a very high standard. Everything was completed neatly and efficiently, and they left the area spotless when the job was finished. The quality of the workmanship is excellent, and they took the time to explain everything clearly before they left. It's refreshing to find a company that takes such pride in their work and provides such great customer service. We wouldn't hesitate to use them again or recommend them to anyone looking for a reliable and skilled plumbing and heating company. Thank you for a fantastic job! ⭐⭐⭐⭐⭐
We are so grateful for Josh and his team. Our solar system was installed poorly by another company and we’ve had nothing but years of problems, Josh has managed to correct it and now it’s running smoothly. I totally would recommend his company and we will continue to use him for the future.
My first call was returned immediately. The work was done in under a week ( not an emergency) the charge was fair and the Chaps were great and friendly. Would thoroughly recommend them.
Great service and a friendly approach as ever from Josh at OffGrid - problem sorted :-)
Excellent communication, arrived on time, leak sorted and I wouldn't hesitate to recommend Josh and his team
Josh and his team went above and beyond. The existing boiler packed up completely. I requested a quote for a new boiler and also a visit to try to temporarily fix the old boiler until the new one was installed. They found time at the start and end of their already busy days to do this - having to attend several times in the 2 weeks it took for the new boiler to arrive. Each visit they were courteous, polite and cleaned up afterwards. The installation of the new boiler was an equally pleasant experience. Everything from quotation, communication and invoicing was fantastic. I have no hesitation in recommending Josh and his team, and will definitely use them for other plumbing work in the future.
Excellent service, Scott was very polite and knowledgeable. Would highly recommend this company
Nathan, Matt and Scott did a wonderful job replacing our shower, and also carried out a very good retrofit to repair another leaking shower in a different room. They did the work at a very fair price and came up with a robust, long lasting repair solution while still keeping things economical. Really pleased with the quality of the work and would happily recommend them.
We wholeheartedly recommend Off Grid Plumbing and Heating. Their work is consistently outstanding, and their team is an absolute pleasure to deal with.
Amazingly helpful, came out next day to fix my boiler. Service and price cannot be beaten.
Great response from Josh .plumbing issue sorted within 24hours. Great communication throughout kept us updated on cost,member of team coming to fix problem and time of arrival. The most professional plumbing company we have ever used.Will be a returning customer.
Excellent and efficient service and Josh is really friendly and leaves no mess. Highly recommend
Had our boiler serviced today after a previously awful experience with another company, and the difference was night and day. The engineer was friendly from the moment they arrived and immediately put our minds at ease. Everything was explained clearly in simple, layman’s terms, and the paperwork was clear, concise, and easy to understand. It’s such a relief to finally find a company that’s professional, trustworthy, and genuinely cares about doing things properly. We’ll definitely be using them again, and I’d have absolutely no hesitation recommending them to anyone.
Great company, we have used them for a new shower installation and complete gas boiler service. Josh turns up on time, very friendly, helpful and knowledgeable in his field of expertise. Josh is willing to do the jobs you want done. We have full confidence in his ability and will continue to use this company for all our plumbing requirements. Highly recommended
Great value for money, very prompt, friendly and reliable service, definitely recommend. Thank you Josh & Scott.
Fantastic service quick friendly and great conversation definitely recommend
Within the agreed time frame, efficient and took away all rubbish. I am very pleased with the work done.
Josh from Off Grid Plumbing and Heating has been our go to plumber and heating engineer for a number of years. Always prompt and attentive, always polite and professional. Josh updates you as he goes so there are no hidden surprises. Josh will often advise you on the most cost efficient way forward. Great service, cannot recommend Josh and the company strongly enough. Dan Truro.
Efficient service, easy to contact and able to fit within timescales. Highly recommend. Thanks Josh
Excellent service - we needed a report in a hurry and Josh was able to do this for us really quickly. I would highly recommend them - best plumbing and heating company in Falmouth!!
After contacting several plumbers and not turning up, Josh came to my rescue. Him and his team were always polite and helpful and went above and beyond to help me.
Absolutely brilliant work, we were very close to having no gas over Christmas (oven and heating). Josh and his team saved the day, in fact one of his team kept working connecting our boiler while the rest of the team were having their Christmas do. They couldn’t have done more and we couldn’t have been more grateful. If you need any plumbing or heating done don’t look any further.
Off Grid was recommended to us by a friend and we wouldn’t hire anyone else now - friendly, always professional, fantastic work. Always has time for people and always makes sure to follow up on issues. Affordable, reliable and just overall wonderful people and wouldn’t go anywhere else.
The team from Off Grid did an excellent job of removing a defunct back boiler from our fireplace. It was a messy job but they cleaned it all up at the end and completed it quickly. This is the 2nd job Off Grid has done for us and I highly recommend them.
INSTALLATION - New shower room. Outstanding workmanship the finish is amazing - Polite unassuming professional and always smiling workmen. Highly recommend Off Grid Plumbing. I will definitely use this company again!
Josh arrived at the arranged time and proceeded to quickly diagnose the fault and repair the boiler, before completing a thorough operational test. He was professional, friendly and polite, answering questions and offering sound advice. We will certainly call on him again for future work and I have no hesitation in recommending him to others.
Have used them for many years Excellent Service, Very Professional and always available to answer the phone or email and respond to our need. First Class.
Was was losing pressure in our oil fired boiler and Josh was fantastic. Great communication, came out quickly after contact. Fixed the issue first time and even went above and beyond by contacting our boiler manufacturer asking about boiler warranty. Booked Josh because of his location but also his brilliant reviews! Would definitely recommend! Thank you
Josh again came to the rescue ! We were left with no heating or hot water after a protracted problem with a gas leak in pipe outside our home. Josh used professionalism and nouce to fix the problem with our boiler which arose due to gas being disconnectef for over three weeks. If there were a six star review, he would get it from us
Josh and the team are fantastic. They are so helpful. Josh took the time to explain what we needed, accommodated the dates when things had to be changed. The team were super friendly and polite. I cannot recommend them enough!
Josh went over and above to repair our broken heating system to restore heating to our home this December 2025. We are so grateful to him and would recommend him in a heartbeat! Very pleasant and helpful. Explaining everything he was doing and why! We will be using him to install a new boiler in the new year 👍
Always only the very best service. Full renovation in my home - two bathrooms and fitted kitchen, water softener, heating and plumbing. Absolutely outstanding and a genuinely nice bloke too!
Excellent service. I had an air source heat pump fitted and Josh and the team were very Professional throughout. I felt comfortable with them coming into my home and their communication was great. I would highly recommend this company.
Arrived on time excellent friendly service reasonably priced
Josh and Matt are very professional, friendly and knowledgeable. Would definitely recommend.
I highly recommend Josh and his Off Grid team. Josh carried out a lpg conversion and service to my boiler and cooker, that was done in a very thorough and professional way. And when the fan on the boiler packed up some months later, he was out that afternoon and fixed it. A very friendly company that I have full confidence in and who give a brilliant service.
Josh and his team are very friendly and professional. Nothing is too much trouble. I recently needed a gas report done as I'm selling my house, Josh fitted me in really quickly, as we're hoping to complete very soon, and the report was sent 2 days later. His team also completely refitted my inlaws bathroom to make it more accessible for them. Mother in law is over the moon and sings their praises to anyone that will listen 🙂 Pricing was clear and up front, no nasty surprises. If you need a plumbing team, use Off Grid, you won't be disappointed.
Amazing service always put safety first Friendly reliable and clean Thank you for fitting our boiler so quickly
Josh has been out a few times to fix my 25 year old boiler…. It finally gave up, so I had to stump up for a new one.. I can not fault this company in any way! New boiler is perfect! Fitted neatly, they left no mess! Really professional and very patient especially with my 80 yr old deaf dad, as I was away on holiday when it was fitted!! Great price great service thank you
The team that installed our new boiler did an outstanding job from start to finish. They arrived right on time, walked us through the entire process, and handled everything with real professionalism. The installation itself was efficient, tidy, and clearly done with care—no corners cut, no surprises. Our home is already noticeably warmer and the system runs beautifully. What impressed me most was how they took the time to explain the new controls and make sure we felt confident using everything before they left. It’s rare to find a crew that combines skill, courtesy, and genuine pride in their work, but they delivered on all fronts. Highly recommend them to anyone looking for quality service and a smooth, stress-free installation.
Thank you to Josh and his team. Nathan and Scott . They fitted my new boiler and a new radiator and new pipework including a more aesthetic mains water pipe to my new remodeled Kitchen. I found Josh and his team professional, efficient and tidy. Even though the weather was against them when they had to fit a new Gas main outside and the heavens opened and both Scott and Nathan got drenched they carried on regardless. I would highly recommend Josh and the team from off Grid Plumbing and Heating due to their First Class Service.
Amazing service. Highly recommended!!
We had an excellent experience with Josh from Off Grid Plumbing and Heating Ltd. He responded immediately when our boiler broke down and we were left with no hot water — a real issue for our family of five! Josh arrived quickly, diagnosed the problem, and had it fixed in no time, keeping us updated throughout. His professionalism, efficiency, and friendly manner were outstanding. We’re so grateful for the swift response and top-quality service. Highly recommend this company to anyone in need of reliable plumbing and heating help!
Top-notch boiler servicing company. They service oil heated boilers too, which many companies don't, so I'd fully recommend them.
My oil boiler had a few problems and the previous maintenance company had failed to find a solution. Off grid really understood what the boiler was doing and quickly diagnosed a faulty diverter valve and body. Brilliant work and I shall certainly use this company again.
Brilliant, professional, now our ‘go to’ team! We had a very old oil boiler which needed replacing and from the initial call to the final fitting the work, communication and professionalism was of an extremely high standard. Josh took the time to speak through all the options for our age/build of house, making it easy to understand and help select our new boiler. Scott and Matt both came to install, they were prompt, polite, tidy (something which is hard to come by these days!) They made me feel completely at ease and would trust them in our home anytime. Josh and his team at Off Grid are simply off THE grid for scoring. We hope to have them back to help us with more renovations very soon!
Josh was recommended to us by friends, we needed a new boiler & oil tank but wanted the boiler fitted in a different place. Josh came and assessed the job and advised us on what was involved.After we got the quote and accepted he fitted us in is diary and the work started. Josh and his team arrived on time and the work started straight away.We have to say that you could not wish to meet a nicer group of people ( Josh- Ben-Scott-Nathan) nothing was to much trouble. We ended up with a very neat & professional Job and even fitted new valves to all our radiators. Highly recommend Offgrid plumbing and heating if you want a neat and professional job. 10/10
Wrong advise
We can highly recommend Off Grid Plumbing and Heating. Communication is excellent. We urgently needed a new boiler and they were prompt and professional. Very knowledgeable and provided us with options to consider. Friendly and reliable service.
So glad I used Josh and Off Grid! Had a broken electric shower which they replaced with a wonderful fancy new shower, plumbed into the mains instead of electric. Josh was great and kept in touch the whole time and had it done within a day, only a few weeks of him coming out to see the shower! Would absolutely recommend!
To start to finish I was very impressed with how polite and helpful they both were I felt safe in there kind presence and over all very happy with the work done and amount it cost I will recommend them And I pray every success to them in the future
Offgrid Plumbing and Heating Contact Josh. I contacted this company asking for help with a broken boiler. From inspection of my problem to having a working system Josh and his team were superb. For me, most important ,no hassle, just a quiet professional technical efficiency. Josh and team were neat and tidy, no mess, they arrived when they said, worked like proper engineers. They have given me a working system ,7 year guarantee, and from my first contact to completion I felt confident this job was going to turn out as unusually easy for me . Terrific job thanks Josh and team at Offgrid Plumbing and Heating. Alex with a happy face
Fantastic plumbing company to use. Extremely knowledgeable & professional, tidy workers, respect your home and do a fantastic job, whether it be fitting or fixing a shower, mending or replacing a boiler. Cannot fault them on any level.
Josh and his team at Off Grid were recommended to us to help out with a plumbing job at our old (and rather wonky) Cornish house. Josh was amazing from the offset- he visited and explained our options, constantly kept us informed of the costs and any changes and the finished product of 2 new fitted toilets, replumbed bath piping and plumbing and fitting a new sink was amazing. They also fully replaced the old soil pipe and did a super job at drilling and tidying up through our Cornish walls. Top team and would highly recommend and use again!
We have used Off Grid Plumbing and Heating for all our plumbing and heating needs. They have fitted a new boiler when our old one was beyond repair, taken care of our annual boiler service and helped us with a water leak in our garden. They are very friendly and take the time to explain any problems they come across. I would thoroughly recommend Josh and his team to anyone.
The job: to modernise the heating and hot water systems in an old granite farmhouse. First visit: Josh impressed us with his explanations, his enthusiasm, his obvious problem solving skills and his attention to detail. By the time he left, we were clear that we would want Off Grid to do the work. Having accepted the estimate, a schedule and starting date were agreed that were subsequently adhered to. The work: Josh and his team were hard workers. They were also friendly and considerate, and did everything possible to minimise mess and upheaval. They were very appreciative of tea and cake! Where changes needed to be made to the plan, these were discussed fully and any price change implications were made clear. The quality of the work was excellent, with real attention to detail and care taken. When making good was necessary, this was done to a high standard. The result: It is now six months since the work was completed. Any snagging was dealt with quickly and we now have a building in which different parts of the house can be heated effectively and economically, and virtually instant hot water from showers and taps. We are absolutely delighted with the work and would highly recommend OffGrid Heating and Plumbing.
Josh and his team did an excellent job, working professional and proficiently. Nothing too much trouble. Would highly recommend.
Great from start to finish, explains well what is needed and discusses the various tradeoffs in approach. High quality work.
We were recommended Off Grid Plumbing by friends. Josh responded to my first message quickly and then came to quote for the work. We've now had a new cylinder and pipework fitted plus an old tank and pump decommissioned. Josh and his colleague started the job promptly on the date and time planned. They were organised, tidy workers and the quality of their work is brilliant. Josh has also been out to us with an emergency, sorting the problem and putting our minds at rest. We have since had Josh quote for several more jobs and we will definitely be using Off Grid Plumbing to complete the work. I have no reservations whatsoever in recommending them.
Josh at OffGrid is always upbeat, polite and capable. He responds quickly and works efficiently. I highly recommend Off Grid.
High praise for this business. We had a 14 year old oil fired boiler which packed up. The response we had was exceptional both in regards to the time it took to arrive on site, the thoroughness of fault finding, and speed at which the repair was carried out. Josh knows his business. Explanation, communication and customer care were first rate. Clearly a perfectionist. Highly recommended.
Cannot recommend these guys enough. If you're thinking of using them, please don't hesitate. Super talented, really friendly, explain everything in simple terms and such a high attention to detail. Thanks so much Josh, Nathan and Scott. Can't wait to use you again for future projects!
Josh helped me out massively when my hot water failed, visited quickly and gave me options to get it fixed as quickly as possible. It is amazing to be able to have a steaming hot shower again. Massive thumbs up!
Josh did a first class job. There was quite a bit to do to get our boiler fixed but he accomplished it very efficiently. It's now running perfectly. Very professional & competent in his work. I'll be sticking with Off Grid for any future matters. First class.
Absolutely first class! Always punctual and polite as well as great knowledge! I am confident Josh will not let you down!
Needed an emergency plumber for a burst pipe. Off Grid we're fantastic. Quick, professional and a quality job. Highly recommend.
I would highly recommend Off Grid Plumbing and Heating. Very professional, friendly and highly knowledgeable.
I cannot recommend Josh at Off Grid Plumbing & Heating more highly. His service is professional, conscientious, and responsive. Josh is technically spot-on and a real problem-solver. This was highlighted when he installed a NEST heating and hot water system and converted towel rails to dual central heating and electrical.
Fantastic plumber, very professional. Wouldn't have anyone else. Has done all our plumbing for us which includes new boiler, sinks, toilet, shower, new radiators in every room, fitted new outside taps and helped with a new kitchen. Thank you Josh.
Thank goodness Josh came when he did and saved our house from a potential flooding (huge thank you!!) - super efficient, clearly knew his work and very passionate in making sure he can sort us with the right boiler. Very grateful that he made sure things were safe on his initial consultation, I have already recommended to a family member & will definitely use you again.
