We worked with GA Electrical and Mechanical on a prominent grade 2 listed house refurbishment in Henley-on-Thames. The project lasted over 12months and involved a great deal of detailed electrical and lighting works. The finished project is second to none and a testament to the team involved. GA were proactive and professional throughout.

I was slightly apprehensive about having a home generator that would be used in the event of a power cut. I need not have worried as I received invaluable guidance from Leigh Vink regarding the purchase of the generator and the cost of the installation.

Our thanks to Glenn Dearlove and his team at GA Electrical and Mechanical. When we needed additional sockets installing in 3 bedrooms, Glenn provided a quotation within 24 hours and offered to have the work completed within 48 hours which suited us admirably.

I was delighted to be working again with GA Electrical and Mechanical at Strodes College. Once again the entire team performed to a very high standard and we managed to hand over an excellent new teaching facility to the school on time.

A massive thank you for all your teams professionalism with the recent electrical works at Lunda and my home in New Yatt. You have played a key role in helping Lynda achieve her goal.

May I express my appreciation for all the hard work and conscientious approach that GA have provided for our project at Alvescot. I am particularly impressed with your approach to the job.

As a company we have always found GA Electrical and Mechanical to be professional, competent and price competitive with an extremely high ethic in producing the very best installation for their client.
