Before you book: heat loss surveys in Dinas Powys
Most homes can run on a heat pump if the system is designed properly, and Dinas Powys is no different. The key is matching the heat pump and radiators to the home's heat loss.
Houses in Dinas Powys built in different eras can need very different heat pump sizes, which is why each is calculated room by room. Homeowners in Dinas Powys 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.
- Anyone getting a heat pump quote, as the first step
- Self-builders and architects who need emitter and system sizes early
- Landlords comparing properties before deciding where to switch first
What's included
- Outdoor unit siting options and noise check
- Radiator schedule with any upgrades needed for each room
- Electrical supply and network operator notes
- Hot water cylinder sizing for your household
- Recommended heat pump size and design flow temperature
Design outdoor temperatures for Dinas Powys and the wider South Glamorgan come from local cold-weather data, not a national average.
Grants and rules for heat pumps in Wales
Homes in Dinas Powys can use the Boiler Upgrade Scheme, which applies in Wales as well as England: £7,500 towards an air source heat pump, or £9,000 when it replaces oil or LPG heating for installations from 21 July 2026 to 31 March 2027. The MCS-certified installer named in your quote applies and deducts the grant.
There is no VAT on installing a heat pump anywhere in the UK, Wales included, until 31 March 2027. Planning rules for heat pumps in Wales are set by the Welsh Government and differ from England's, so the surveyor checks the unit position against them.

Winter daylight and heating in Dinas Powys
On the shortest day Dinas Powys gets about 7 hours 50 minutes of daylight, and the winter sun reaches only around 15° 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 Dinas Powys: questions
What size heat pump does a Dinas Powys 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 Dinas Powys home.
Do I need new radiators for a heat pump in Dinas Powys?
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 Dinas Powys home gives a room-by-room list.
How soon can you survey a home in Dinas Powys?
Survey dates depend on how busy installers are in South Glamorgan. We offer the next available dates when you enquire and confirm them in writing.
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.
