Established in 1988 by Michael Wells, Interheat is a family run business that has been offering unparalleled service for over 20 years. Michael started out in the industry as a British Gas engineer but always harbored the ambition to start his own business. He saw a gap in the market for somewhere that offered friendly and professional service that could understand the needs of the customer when it came to plumbing and central heating. That’s when he opened the Interheat showroom in Carshalton. Today, we’ve increased our skill set, but it’s still from this same central hub that we maintain and install boilers and central heating systems, fit bathrooms and install cookers, fireplaces & surrounds all over South London and Surrey.

Two decades later and the ethos that forged the business still remains at its heart. The Carshalton showroom has grown and our skills have diversified, but our approach to our work remains the same. At Interheat we don’t believe in subcontracting work out to people we don’t know. Instead we hire and train our engineers directly, ensuring that the high standards we set ourselves are upheld.

All Interheat engineers hold their current Gas Safe registration.

Interheat is an approved installer for Worcester Bosch boilers.

Interheat won the South London Energy Efficiency Award and offer a range of services to help your home run greener.

The Carshalton showroom has a vast display of gas and electric fires / fire surrounds / gas boilers / radiators / bathroom suites / and gas cookers. We are able to install all of the items we stock, and though we always advise that our products are fitted by one of our trained engineers, we can act as just a supplier if alternative methods of installation are preferred.

At Interheat it’s our job to understand how important keeping the cold out, the gas on and the water running is to your home. To ensure that you shouldn’t be uncomfortable any longer than you have to, we now offer finance facilities to help spread the cost.

We undertake a range of tasks, and no job is too big or small, from large commercial operations to private work in the home.
