What Our Customers Say

Don't take our word for it. Here's what real homeowners and landlords say about working with us.

I highly recommend ARG Contracts, very professional and friendly. All work was tidied up once finished. I am very pleased with the outcome with my new boiler.
Michelle
Homeowner
I found Richard & his team to be very helpful & they got the works done quickly. The boiler has never worked so well, would definitely use them again.
Zoe
Homeowner
Fantastic service from Rich & his team fitting our new boiler & shower on the same day. No mess was left by the team. Will definitely be using their services again.
Mark
Homeowner
Richard completed extensive plumbing and heating work in our home to an excellent standard, including a full downstairs replumb, new radiators, a relocated and newly fitted boiler, an outside tap, and a fully installed kitchen with integrated appliances. He also created a brand new downstairs cloakroom, going above and beyond to ensure a neat, seamless finish. He was reliable, knowledgeable, hardworking, and took real pride in his work — we would highly recommend him as a trusted, skilled plumber and heating engineer.
