What to know about heat loss surveys in Tavistock
Most homes can run on a heat pump if the system is designed properly, and Tavistock is no different. The key is matching the heat pump and radiators to the home's heat loss.
A surveyor visits your Tavistock home to measure each room, window and wall before any heat pump is sized. Design outdoor temperatures for Tavistock and the wider Devon come from local cold-weather data, not a national average.
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.
- Self-builders and architects who need emitter and system sizes early
- Homes with an existing heat pump that seems undersized or expensive to run
- Landlords comparing properties before deciding where to switch first
What's included
- Hot water cylinder sizing for your household
- Outdoor unit siting options and noise check
- Radiator schedule with any upgrades needed for each room
- Written results in your quote, or a stand-alone report if you order one
- Recommended heat pump size and design flow temperature
The survey in Tavistock includes a check of where the outdoor unit could sit and how its sound would reach neighbours.
Grants and rules for heat pumps in England
Homes in Tavistock 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.

Designing for Tavistock's winters
On the shortest day Tavistock gets about 7 hours 59 minutes of daylight, and the winter sun reaches only around 16° above the horizon at noon. Winters this far south are milder than in most of the UK, which helps a heat pump run at low flow temperatures for much of the season.

Heat loss surveys in Tavistock: questions
How long does a heat pump survey take in Tavistock?
A home survey in Tavistock 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.
Do you cover Plymouth as well as Tavistock?
Yes. We arrange surveys and installation in Plymouth, which is about 12 miles south of Tavistock, and across Devon.
Do I need new radiators for a heat pump in Tavistock?
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 Tavistock home gives a room-by-room list.
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.
