I would highly recommend them for any work in the futurePosted on Jamie HorsleyTrustindex verifies that the original source of the review is Google. Superb service from start to finish. After being let down by others builders not it was refreshing to see Steve arrive on time to quote, fully armed with good ideas on how things could be done better. That set the tone for what turned out to be a smooth running building project, mess kept to a minimum and Steve’s own electrical work was second to none. Will 100% be using them again for future building work and recommend to all friends and family.Posted on Alex HamiltonTrustindex verifies that the original source of the review is Google.

On time and budget.Posted on Lewis FinneyTrustindex verifies that the original source of the review is Google. Kitchen refit completed to the highest standard with no corners cut! Communicated well keeping me informed of any issues along the way. Continously showing work throughout to show high standards Very happy!Posted on Andrew ParsonsTrustindex verifies that the original source of the review is Google. Steve came out and quoted me on a full rewire with a new fuse board and his price was good. Steve has a good reputation locally so I knew I was in good hands. Steve arrived on time, put covers down everywhere and cracked on. His wiring was really neat and tidy and he didn't leave any mess after, a proper job well l done. I will defo use again. Would like to add an update 01/06/23. Had Steve back out to do some small building work at my house after seeing his recent renovation work...WOW absolutely over the moon and I can honestly say, zero stress whatsoever. Everything cleaned down every day, hardly any dust, all trades on site when he said they'd be there and all super professional. I would also like to add, Steve and jess kept me informed at every step, a superb service and a super finish
