My lights went intermittently on and off and I called them to visit. The electrician told me it was the dimmer and apparently fixed the problem. The same thing happened again so they sent him back (with no mention I would have to pay again for another visit). The day he came they just happened to be back on. Two days later they went again yet they are trying to charge me for a second visit even though the issue wasn't fixed in the first place and the lights continued to go on and off intermittently. He was in my house for 5 minutes and they want another £90 even though the lights are still not working. They keep sending an invoice and also had the cheek to suggest I pay £180 for a wiring check. If that is the problem then their engineer should have discovered that in the first place. Will never use again and certainly would not recommend them to anyone.
The electrician was smart very polite & took time to explain exactly what the fault was, he suggested the most cost effective solution & once agreed carried out the repair quickly without any fuss or mess.
