Air source heat pump installation in Sedgefield: what to expect
Homes around Sedgefield range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
For older properties in Sedgefield, the heat loss calculation looks closely at solid walls, single glazing and draughts before any unit is sized. Installers working in Sedgefield plan the order of work so heating and hot water are off for as short a time as practical.
We survey your home, design a heat pump system around its real heat loss, and manage the installation from the first visit to the MCS certificate.
- Owners who want one contract covering design, fitting and paperwork
- Homes replacing a gas, oil, LPG or electric heating system
- Owners and landlords in England and Wales eligible for the Boiler Upgrade Scheme
What's included
- Outdoor unit, hot water cylinder and weather compensation controls
- Radiator and pipework changes where the design needs them
- Commissioning, handover and a walk-through of the controls
- Free home survey and room-by-room heat loss calculation
- Boiler Upgrade Scheme application in England and Wales where eligible
Homeowners across County Durham can arrange a survey in Sedgefield for a room-by-room design and a written quote before committing to anything.
Grants and rules for heat pumps in England
In England the Boiler Upgrade Scheme gives £7,500 towards an air source heat pump (£9,000 if it replaces oil or LPG, from 21 July 2026 to 31 March 2027), and since 28 April 2026 a valid EPC is no longer needed. The grant is applied for by the MCS-certified installer and shown as a deduction on your Sedgefield quote.
There is no VAT on installing a heat pump anywhere in the UK until 31 March 2027. In England most houses can have an air source heat pump under permitted development, provided the unit meets the MCS noise and siting standards; the old 1 m boundary limit was removed on 29 May 2025. We flag listed buildings, flats and sensitive conservation-area positions at survey.

Air source heat pump installation in Sedgefield: questions
Do I need new radiators for a heat pump in Sedgefield?
Often some, not all. Heat pumps run best at lower water temperatures, so rooms with small radiators may need larger ones. The survey of your Sedgefield home gives a room-by-room list.
How long does installation take in Sedgefield?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Sedgefield home states the expected time.
How long does a heat pump survey take in Sedgefield?
A home survey in Sedgefield usually takes one to two hours. The surveyor measures every heated room, checks windows, walls and radiators, and looks at where the outdoor unit and cylinder can go.
Can I cancel after accepting the quote?
Nothing is ordered until you accept the written quote. Where the contract is agreed away from our premises, for example at your kitchen table, you can cancel within 14 days under the Consumer Contracts Regulations 2013. If you ask us to start sooner and then cancel, you pay only for work done up to that point.
What grants can I get for a heat pump?
It depends on where you live. In England and Wales the Boiler Upgrade Scheme gives £7,500 towards an air-to-water heat pump, which the installer claims and deducts from your quote. In Scotland, Home Energy Scotland offers a grant of up to £7,500, with up to £1,500 more for eligible rural and island homes, but you need a written funding offer before work starts. Northern Ireland has no dedicated homeowner heat pump grant at present.
