Outdoor Electrical Socket Installation
Posted 15 June
Excellent service from Luke from start to finish. Jamie did the installation of an outdoor socket for me. The work was clean and tidy. Will use them again in the future and recommend them to anyone looking to have some electrical work done.

Luke’s carried out a few jobs on our house and I wouldn’t go anywhere else, always professional and reliable and has very good attention to detail. Really happy with my media wall + my cctv / alarm set up.

Full electrical rewire
Posted 13 May 2024
Luke and his team at LT Electrical did an amazing job of rewiring my house, Highly trustworthy and very professional. Considering all the work was carried out whilst we were still in the property the guys were very considerate and took exceptional care when moving stuff around during the process and always making sure the place was neat and tidy at the end of each day. Would recommend Luke and the LT team to anyone 100%
