4.9
Many customers report effective communication from office staff and polite tradespeople who carry out prompt electrical, gas, and plumbing repairs. However, critical reviews mention instances of last-minute appointment cancellations, misdiagnosed electrical faults, and poor finishing quality on larger flat refurbishment projects. A few clients also experienced long delays in scheduling or completing requested works.
Summarised with AI
Unreliable. Every time they give us an appointment they have cancelled it last minute. I imagine they are cheap, because my landlord has two other companies (which I think were very professional) investigating the issues and making quotes, and at the end decided to send this one. The person that came (after rescheduling) was friendly and made an OK job, but If it was me paying, I would definitely pick a different one.
I would like to start by saying thank you to the whole team that where very patient and helpful, special thanks to volkan who assisted me to decide which tiles I wanted as I was being very picky, excellent service and cheap prices.
Ariana and the On the House team have been so great and reliable- thankyou so much for your time and hard work
Quick and professional service from the engineer. Adriana was great in co-ordinating the appointment and flexible on timings.
It was a lovely experience dealing with this company for the electrical issue at my house. The communication with Adriana the manager was very fantastic as they kept me in the loop from the beginning of the appointment right to when the engineer visited. The engineer was also very helpful and went above and beyond to sort out issues. I highly recommend On The House to anyone looking to do electrical work at their home or business.
Very efficient service. Polite contractor and friendly. Did the task assigned to him with professionalism. Thanks again
Your fitting was very quick and neat . Good time keeping.
I’m very happy with the service provided. The plumbing issue was resolved quickly and professionally, and everything was left clean and in great condition afterwards. A special thank you to Adriana for the excellent communication and support throughout the process—it made everything smooth and stress-free. Highly recommended!
Great service - prompt communication from Adriana, contractors arrived on time, super polite, efficient and professional. Highly recommend!
Excellent service overall. Adriana was very helpful in rearranging the appointment and the electrician who attended was polite, professional and efficient. The repair was done quickly and everything was left clean and tidy. Many thanks
Complete joke, a month to come and measure, paid never heard from them again, out if the blue they said oh sorry first one, someone was sick then engineer didn’t revert then oh you asked to measure bedroom too…. Wasting my time for two months, a joke of a company
The gentleman was very thorough for the leak and explained to us what the further damages were. I felt reassured that my issues were taken seriously and kindly by the team. The assured me they would explain the issue to the agent as well. I hope that the agent agrees to further repairs with them because they were very skilled and trustworthy.
Excellent job. We had a leak into our kitchen ceiling from our bathroom which was sorted professionally and swiftly. Highly recommend the contractor on the job
Really great service, super speedy reply and actioned the issue within a day! Big thank you to Adriana for organising the service so quickly, and thank you to the engineer Darish who was kind, professional and able to resolve the issue promptly! :)
Adriana did an excellent job handling the gas certificate issue. Everything was completed quickly, professionally, and with great communication throughout the process. I’m very pleased with the service and would definitely recommend Adriana for any future property repairs or certifications.
Great, speedy and efficient response within a few hours from Kevin, Adriana and Md Imran. Can’t fault them!
Great experience with OnTheHouse! They fixed a mold issue in my flat quickly and professionally. Cath from the agency was incredibly nice and very helpful throughout the process. The engineers (Andreas Olti) were super professional, kind, and efficient. Highly recommend!
I really doubt about the reviews here are genuine or not. This company deserves NO star, but I am unable to rate it as zero start. The fisrt appointment was cancelled in short notice by On the House, then the contractors came on another date with his van parked on my neighbour's driveway!! My neighbour complains to me how rude these people are. They even made a scratch and paint tear-off on the car next to it. Claimed they knocked my door but no one was inside, claimed they called you but not calling your mobile number. And then the company said they even reserved the right to charge a call-out fee for the missed appointment!! Avoid this company!!
When electrician did arrive he was pleasant and very efficient - However he arrived at 7.20 pm. Also we had been without hot water for a week
I'm extremely impressed with the service provided. The team was very quick to respond, and their communication throughout was clear and professional, especially Mary. What stood out most was the engineer’s professional approach — it made me feel completely at ease having them in my home. It’s reassuring to deal with a company that values both efficiency and customer trust. Highly recommend! Dan :)
Really happy with the service. The gas engineer arrived on time, was friendly, and did a great job. Everything was easy to arrange, and Adriana kept me well informed throughout. Thanks for making it all so straightforward!
This was a fast and effective service to get our shower drain unblocked. The plumber, Christopher was nice and sorted the job in 5 minutes, tidying up after himself. Darish organised and oversaw the appointment by phone, and was very responsive and easy to communicate with. Would recommend
We’ve had an excellent experience with on the house.From the beginning, everything has been handled with professionalism and efficiency. I especially want to mention Catherine , who has been a tremendous help throughout the process. She’s responsive, knowledgeable, and always willing to go the extra mile to make sure everything runs smoothly. Whether it was coordinating maintenance, answering our questions, or providing timely updates, Catherine has consistently exceeded our expectations. Donato
The cooker hood at my rental property had stopped working. An electrician from On The House attended, couldn't locate the spur nor figure out what the electrical issue was and therefore suggested installing a new cooker hood with new wiring, spur, the works. Quoted £1000 for this work... Another electrician attended, found the spur in a kitchen cupboard, hidden behind the contents which had been pushed back, and the switch pushed into the off position. So are your electricians incompetent or con artists?! Either way, I would definitely not recommend!
We had a broken boiler. First engineer to come round to fix it was a painter who came round to take a photo of the error, so not a good start. The next day another guy came round who could not fix it, but he called another chap who was an expert on Worcester boilers and he fixed it in no time. Throughout the whole experience, although frustrating having to chase appointments, Louisa handled everything very professionally and always kept her promises to calm me back. Thanks Louisa
We bought a property and we start working with On the house for its refurbishment. - flooring was done properly, nothing to say about that - painting of the whole flat has been a joke, painters had to come 5-6 times to complete doing an horrendous job - after sending the pictures of the wall, they even suggested that we touched the wall ourselves!! - installation of the sliding door: we asked for a normal size door which is 80cm, they did a door of 67cm, much smaller; we asked them to re do it - a sink was installed by them in our kitchen, after few days it was leaking but they did not want to come as they were saying the leak is not connected to the job they did… long story short, we called an external plumber and he confirm that the sink installed by them was faulty. All the works should have been completed by end of March - in reality the last painter’s visit has bern end of May (2 months after). I definitely wouldn’t recommend it, a lot of stress and money for a mediocre job!!
Good repairs to worn out locks.
Prompt service. Staff were very helpful without being pushy & very pleasant.
