10 Great dad and daughter duo
Posted 27 February
Super friendly duo of dad and daughter who have done a great job for us. They replaced our old consumer unit, kitchen spotlights, added new sockets and put in a bathroom extraction fan. All done to top standard including helping us clean up afterwards. Would highly recommend.Verified reviewerJob location: CF5 10 Excellent service

Great service start to finish. Had an issue with one light which was causing issues in another room intermittently. The electrician came in and was very thorough in his search for the fault - turned out to be more than one! He stayed to resolve the issue for us despite having other jobs to go to as well. Can't thank them enough for fixing this for us as it had been bugging us for months! Would highly recommend and will be the only electrician we use going forward.Verified reviewerJob location: NP2310 New sockets installed outside and fuse board updated

Richard was amazing from start to finish. He came out and gave a quote and really understood the assignment and budget constraints. He proposed a viable solution and carried out quickly. On the day of installation he called to say he was 20 mins away, carried out the work without an issue. Highly recommended and have already passed his number on to friends and family.Verified reviewerJob location: NP12- CCameron
