Solomon replied to my ad very quickly which was great and he managed to get the heating working in my flat, which it hadn't been. However, the fault light on my boiler came back on shortly after he left and he hasn't been able to provide a report on what issue needs fixing for me to be able to follow up on. He also wouldn't pre confirm an hourly rate or agree costs upfront. He was however very friendly and helpful, if he can provide a report and rectify the issue then I'd happily use him again.

Relm were fantastic. I have done a lot of renovations over the years but our regular builders weren’t available and we had to get the job done on short notice. Relm were professional, helpful and most notably stayed on time and on budget. I wasn’t able to be onsite and they kept me up to date with photos and videos. They left the building site clean and tidy and I am delighted with the quality of the workmanship. I wouldn’t hesitate to use them again or recommend them to friends.
