This is the second time we have used Thunder Electrical Services Ltd. We are really happy with the communication around the work and the standard of work carried out. Reasonable price. To date Jacek has replaced a consumer board and a light fitting.

Value for money
Posted 19 February
I got a quote from Jacek from Thunder Electrical Services Limited. It was a fair and competitive quote. I have previously had Jack and his team do a full refurbishment on another flat for me, so it made sense. Jacek is very professional, and knowledgeable. He is very experienced. His attention to detail is second to none. I highly recommend Jacek and his team from Thunder Electrical Services Limited for big and small projects, and I will definitely be using them again for my next project.

Highly knowledgeable electrician, excellent service
Posted 16 February
Thunder Electrical Services provided a great service to inspect the electrics in my house prior to a cooker installation. Jacek figured out the best route to create a connection in a dated Victorian home. He is very knowledgeable and professional and he will back to do the full install. Highly recommended. Thank you
