Recent Testimonials

We would like to thank Terry and his team at Argonaut Heating for our new boiler at St Mary’s C of E Primary School, East Barnet.

From the first phone call I made it’s been a breeze, very helpful and always there if you have a question. As with any works we have here, we have a number of companies come to give quotes and Argonaut Heating came out with the best quote – but not just that, an easy to understand breakdown of what we need and what will work for our school. All work taken place was clean and safe with a friendly team that talked you through what you wanted to know. Fully recommend this company which are very hard to find these days.

Thanks once again.
