Air source heat pump installation in Tewkesbury: what to expect
Homes around Tewkesbury range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
Homeowners across Gloucestershire can arrange a survey in Tewkesbury for a room-by-room design and a written quote before committing to anything. Terraced streets in Tewkesbury often mean a compact unit position at the rear, so siting and sound levels are checked carefully.
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 and landlords in England and Wales eligible for the Boiler Upgrade Scheme
- Houses with reasonable insulation, or a plan to improve it
- Households with room for a hot water cylinder
What's included
- Boiler Upgrade Scheme application in England and Wales where eligible
- System design, unit sizing and a written quote
- Commissioning, handover and a walk-through of the controls
- Radiator and pipework changes where the design needs them
- Removal of the old boiler or heaters
In Tewkesbury, cylinder space is planned with you, often in an airing cupboard, utility room or garage.
Grants and rules for heat pumps in England
Homes in Tewkesbury can use the Boiler Upgrade Scheme, which takes £7,500 off the cost of an air source heat pump when it replaces fossil-fuel or electric heating. Replacing oil or LPG heating qualifies for £9,000 for installations from 21 July 2026 to 31 March 2027, and air-to-air systems for £2,500. The MCS-certified installer named in your quote applies for the grant and deducts it from the price.
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.
What to budget for air source heat pump installation in Tewkesbury
The ranges below are typical installed prices for homes in Gloucestershire, including VAT. A survey sets the exact figure, because two similar-looking houses in Tewkesbury can need quite different radiators and pipework.

On the shortest day Tewkesbury gets about 7 hours 44 minutes of daylight, with the noon sun around 15° up. The heating season runs from autumn into spring, so a heat pump that is sized correctly and set up with weather compensation does most of its work in steady, cool conditions.

Air source heat pump installation in Tewkesbury: questions
Do I need new radiators for a heat pump in Tewkesbury?
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 Tewkesbury home gives a room-by-room list.
Can you service a heat pump in Tewkesbury that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Tewkesbury, whoever fitted them. Tell us the make and model when you book.
What size heat pump does a Tewkesbury home need?
It depends on the heat loss, not the postcode. As a rough guide, a 3 bedroom semi often needs 6–9 kW, but the room-by-room survey sets the actual size for your Tewkesbury home.
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.
Do I need new radiators for a heat pump?
Not always; many homes keep most of their radiators and change only a few. Because a heat pump runs at a lower water temperature than a boiler, each radiator gives out less heat, so the survey checks every room against its heat loss. Rooms where the existing radiator falls short get a larger one, with a guide price of £250–£450 each, installed and including VAT.
