An example of our electrical work

We completed a project for clients in Quentin Road, Blackheath SE13 5DG. We were called in to install first fix internal lighting, as well as second fix external lighting to cladding for the client’s new outbuilding. The service we provided was completely bespoke and flexible – we were held up in our installation of the external lights due to other tradespeople overrunning, but we made sure we could still accommodate the client’s requirements.

This is what our client said about our service:
“I had exterior lights installed which look fabulous. I also had garden electrical sockets fitted and shed lighting. The work was done promptly and efficiently! Would use O’Briens again.”
