Before you book: heat loss surveys in Tewkesbury
Homes around Tewkesbury range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
The survey in Tewkesbury includes a check of where the outdoor unit could sit and how its sound would reach neighbours. Homeowners in Tewkesbury thinking about insulation work can use the survey to see how it would change their heat pump size.
Every heat pump we quote starts with a room-by-room heat loss survey, free with installation enquiries and also available as a stand-alone report.
- Homeowners planning insulation or building work who want to know the effect on heat demand
- Landlords comparing properties before deciding where to switch first
- Anyone getting a heat pump quote, as the first step
What's included
- Recommended heat pump size and design flow temperature
- Electrical supply and network operator notes
- Room-by-room heat loss calculation using the MCS method
- Written results in your quote, or a stand-alone report if you order one
- Hot water cylinder sizing for your household
Design outdoor temperatures for Tewkesbury and the wider Gloucestershire come from local cold-weather data, not a national average.
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 Tewkesbury quote.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Since 29 May 2025, permitted development in England allows up to two air source heat pumps on a house, each up to 1.5 m³, with no blanket 1 m boundary rule — the installation must still meet the MCS planning standards, including the noise check. Listed buildings, flats and some conservation-area positions need extra consent, which we check at survey.
Heat loss survey prices in Tewkesbury
Guide prices for Tewkesbury and the rest of Gloucestershire are shown below, installed and inc VAT. We publish ranges rather than a single figure because design details move the price, and the written quote after survey fixes it.
| Survey | Guide price |
|---|---|
| Home survey and heat loss calculation with an installation quote | Free |
| Stand-alone heat loss survey and report | £150–£400 |
Inc VAT. A stand-alone report is for homeowners who want the design without an installation quote.
Designing for Tewkesbury's winters
Tewkesbury has about 7 hours 44 minutes of daylight at midwinter and 16 hours 44 minutes at midsummer. That swing matters if you pair a heat pump with solar panels: summer generation can cover much of the hot water, winter generation far less.
The steps for heat loss surveys in Tewkesbury
- Tell us about your home: postcode, property type and current heating.
- We book a survey in Tewkesbury; the surveyor measures rooms, windows and radiators and looks at cylinder space.
- The design and quote arrive in writing, including radiator changes and the outdoor unit position.
- On installation days the old system is removed and the new one fitted and filled.
- We commission the heat pump, show you the controls and register the installation.
Heat loss surveys in Tewkesbury: questions
Do you cover Cheltenham as well as Tewkesbury?
Yes. We arrange surveys and installation in Cheltenham, which is about 7 miles south-east of Tewkesbury, and across Gloucestershire.
How long does installation take in Tewkesbury?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Tewkesbury home states the expected time.
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.
Is the heat loss survey free?
Yes, for installation enquiries the home survey and heat loss calculation are free, and the results form the basis of your written quote. If you only want the calculation and report, for example for building plans or comparing quotes, a stand-alone heat loss survey has a guide price of £150–£400, including VAT. We confirm which applies when you book.
How long does a heat loss survey take?
A typical survey takes 1–3 hours on site, depending on the size and complexity of the home. Larger or older houses with mixed construction, extensions or many rooms take longer. The calculations and design are completed afterwards, and the results are included in your quote or stand-alone report.
