Nathan installed a consumer unit, socket outlets, linear luminaire and light switches in the garage and connected the LV supply cable to the house utility supply. The price was competitive and quality of the work was great. He is professional and came to do the work on the day it was agreed. I will contact Nathan when I need any other electrical work and I will recommend him to family and friends.

Zoltan was great. He took the time to design and plan with us, had a lot of patience for working out the detail... he was very clear in giving us timing brackets and delivering within that time. He loves what he does, and that is very visible in the quality of the carpentry and joinery he delivers. We would definitely recommend him to anyone as we are very happy with the results.
