Heat Pump Installers Sunderland: MCS and BUS Grant

Sunderland has a lot of the homes heat pumps suit best. 45% of households lived in a semi in 2021 and 13.3% in a detached house, most with a garden or side passage for the outdoor unit. Only 10% lived in purpose-built flats.

Sunderland homeowners can claim £7,500 from the Boiler Upgrade Scheme towards an air or ground source heat pump, whatever their income. Your MCS installer applies for it.

Survey first, unit second

A good installer works out heat loss room by room, then checks if each radiator is big enough at the lower water temperature a heat pump runs at. Expect some radiators to be replaced. Our air source heat pumps guide explains the basics, and the heat pump cost guide covers totals.

Insulation comes first. Topping up a thin loft and filling an empty cavity can cut the size and price of the heat pump.

Hard water and the cylinder

A heat pump heats a hot water cylinder rather than heating water on demand. In the harder Sunderland zones, where averages run above 200 mg/l, scale can build on the cylinder coil. Ask the installer about a scale reducer on the cold feed to the cylinder.

By the sea

Salt air at Roker and Seaburn is hard on outdoor metalwork. Ask for a unit with a coastal coating, or one the maker approves for coastal sites, and site it out of direct sea spray.

Planning

One unit on a house is usually permitted development if it's under 1.5 cubic metres and meets the noise rules. Listed buildings and front walls facing a road in a conservation area need extra care.

Sunderland homes and what they need

Single-storey cottages and two-storey terraces

Single-storey cottages have a big roof area relative to their walls, so loft insulation matters a lot. The cylinder needs a home too, which can be a squeeze where there's no upstairs.

Interwar and post-war semis

The airing cupboard usually takes the new cylinder, and the side passage or back garden takes the unit. These are often the simplest installs in the city.

Newer estate homes

With good insulation already, most radiators may stay. Check estate covenants about outdoor equipment before choosing a spot.

Areas covered

Engineers who cover Sunderland work across areas including Roker, Seaburn, Fulwell, Ashbrooke, Millfield, Hendon, Southwick, Doxford Park, Washington and Houghton-le-Spring.

Questions people in Sunderland ask

Is a hybrid with my old gas boiler eligible?

No. The Boiler Upgrade Scheme doesn't fund hybrid systems that keep a gas boiler.

How long does an install take?

Most semis take three to five days, including radiator changes and the new cylinder. You'll be without heating for part of that time.
