Highly recommend Ben for plumbing and rendering work! He did a fantastic job — everything was completed to a high standard, on time, and within budget. Very honest, easy to communicate with, and offered practical solutions without upselling. His pricing was fair and transparent, and the quality of work speaks for itself. It’s rare to find someone so reliable and skilled these days — will definitely be using him again!

Atheca are just brilliant! A rare find. Thiago leads with an extremely amiable, professional, thoughtful, flexible, and meticulous service. He is competitive and transparent in his pricing, proactive on the job to suggest solutions where needed, and has superb attention to detail and pride in his work. I trusted him to work in my house and although his team don’t all speak English, he was always overseeing things and accountable and perfectionist. Couldn’t recommend more.

Very professional. Arrived on time, immediately started putting down floor protection from the front door right the way through to the studio room. Said what time they would be finished and actually finished a little early. Did a good job of cleaning up after. And as for the plastering, it’s some of the best I’ve seen! Absolutely fantastic. I would thoroughly recommend them, and would use them again in a heartbeat!

One to be careful with is the electrician Ben. The work seems alright, but his advise left us with excessive lighting in Kitchen and sitting room and our decision against TV sockets in ALL rooms was interpreted as NO TV and phone socket at all, which then later had to be added at extra cost and left the choice of suppliers limited. His crew also did the plumbing and the bathroom installation and the later was not done to the general standard of U&U constructions work.
