Called me ten minutes after placing the request. Daniel immediately arranged to do the job the next morning and gave me a cost at the same time. He called me twenty minutes prior to his arrival. When he arrived, we discussed the work in more detail and he completed everything very quickly and neatly. Provided a test certificate as requested. He was a very pleasant and professional. This is what I expect from a company who is registered as a NIC EIC electrician and would recommend others to do the same.

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.
