Kitchen Fitting- 14 Jan 2026
My initial experience with Solis Power Limited was Leo’s immediate response within 30 minutes, visited my property to view my kitchen. He gave a full detailed breakdown of price list that explains each work to be carried out. Suggested materials to use also help with the purchase. Leo and his team are perfect working together, cleaned after themselves each day. They installed new electrical unit, also introduced registered gas man to run gas pipes and also connect the gas hob. Plumbing work was excellent too. Leo also helped with the measurements of splashback and splash splatter guard. The work was carried out within five working days delay was due to shortage of splashback in the store. I highly recommend Leo and his team.

Bathroom Fitting- 14 Nov 2019
We had our bathroom completely refurbished and Graham the owner was lovely. He came to give us the quote, visited whilst work was being undertaken to make sure everything was okay and came to make sure everything was finished to how we wanted it. The work carried out was of a high standard and whilst the bathroom work was being completed we also ended up getting our kitchen worktops done by Graham’s team. Chris was the one who carried out our work, he was very friendly and checked we were happy with the work he’d done before he left everyday. I would use Graham again for other work needed around the house.

Extensions- 11 Apr 2024
AMAZING CONTRACTORS ! Mali Constructions did an absolutely amazing job. They were professional and vey friendly. The works took 3 weeks and Mali ensured the works were carried out with high expertise. Such a smooth and great service and worthy every penny. The pricing was reasonable and within my budget and I was kept informed throughout the whole process. The project was completed to a great standard and we are very happy with our new space and would absolutely recommend Mali Construction to anyone looking to complete work. If you are looking for a contractor with great communication, great workmanship and priced correctly, I would definitely use Mali Construction Ltd. Mali would provide regular updates, discussions and even worked with my many changes to the plans during the process with no issues. No matter time or day, they were always on hand to respond to any questions. They were also quick to point out unnecessary extras that ended up saving us money.

Extensions- 15 Aug 2018
100% RECOMMENDED Michelle and her partner measured up and competitively quoted within a short space of time. She was then very patient and supportive when unforeseen planning issues popped up and set the start date back by quite some time. Once building started, all questions were promptly answered by either the site manager or Michelle, both being available at all times. I was away for the duration of most of the job and it was very reassuring to know that I was leaving it all in capable and honest hands. The workers were very proficient and tidied up after themselves at end of each day. They also put in some very long hours at times to hasten the work. I was also impressed by the handling of unexpected problems during the building (mainly invasive tree stumps!). I am absolutely thrilled with the end result. High quality workmanship and a beautiful building which I am sure will last many years. I would certainly recommend them without a doubt.

Extensions- 7 Jun 2026
Zilvinas and the team at Innovate Builders were outstanding from start to finish. We hired them to build our two-storey side extension. Zilvinas was open, professional, and fully committed throughout the project. He was always available to answer questions, offer advice, and guide us through each stage of the build. His team worked hard and delivered a high-quality finish, all while keeping the project on schedule and within budget. As this was our first major building project, we relied heavily on Zilvinas's expertise and guidance. His knowledge, practical advice, and problem-solving skills were invaluable and made what could have been a stressful experience feel smooth and manageable. We are absolutely delighted with the result and would not hesitate to recommend Innovate Builder. As I said it was our first ever big project, we had heard many horror stories but are so grateful to have found Zilvinas and his team.

CJ was excellent from start to finish. He’s reliable, punctual, and a true one-man band who took care of everything himself. He fully embraced our bold design and helped bring it to life with great attention to detail. We were so pleased with the result that we’ve already booked him for our second project, and would highly recommend him to anyone looking for a skilled and trustworthy bathroom fitter

What experience do you have with similar extensions in Colney Hatch?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Colney Hatch extension builder’s ability to deliver a result that meets your expectations.
