Heat Pumps in Sutton
Heat pump installation is the fitting of an air-source heat pump and associated hot water cylinder as a replacement for, or alternative to, a gas boiler, sized to the property's heat loss and often eligible for the government's Boiler Upgrade Scheme (BUS) grant.
In Sutton, that covers Cheam, Carshalton, Wallington, Belmont, North Cheam. Sutton is a residential outer-London borough with a traditional High Street and well-established suburbs across Cheam, Carshalton and Wallington, offering a mix of interwar family housing and period properties close to Carshalton's historic ponds and village core, within reach of our Croydon and Surrey teams.

Property styles in Sutton
The borough has a strong stock of 1920s and 1930s semis and detached houses across Cheam, North Cheam and Belmont, alongside Victorian and Edwardian houses in the older parts of Carshalton and Wallington. Rear and side-return extensions and loft conversions are common on the semi-detached stock typical of the area.
Planning considerations
Sutton Council (London Borough of Sutton) is the local planning authority. Carshalton village and parts of Cheam and Wallington are conservation areas with a number of listed buildings around the historic ponds, which affects alterations to visible elevations and materials. We confirm the position for individual properties at feasibility stage.

FAQs
Heat Pumps in Sutton: FAQs
Do you provide heat pumps across all of Sutton?
Yes, we cover the SM1, SM2, SM3, SM5 and SM6 postcode areas in full, including Cheam, Carshalton, Wallington, Belmont, North Cheam.
Will I need to replace my radiators for a heat pump?
Often, yes — heat pumps run most efficiently at lower flow temperatures than a gas boiler, so existing radiators are sometimes undersized for the new system. We assess this during the heat loss survey and specify any radiator or underfloor heating changes needed.
What is the Boiler Upgrade Scheme (BUS) grant?
It's a government grant offering a fixed contribution toward the cost of installing an air-source or ground-source heat pump in England and Wales. Eligibility depends on the property and installer, so we advise on the likely position but can't guarantee an award.
Do you cover Carshalton and Wallington as well as Sutton town centre?
Yes, we work across the SM1, SM2, SM3, SM5 and SM6 postcode areas, including Sutton town centre, Cheam, Carshalton, Wallington and Belmont.
