Before you book: heat loss surveys in Maesteg
The question for a Maesteg home is rarely whether a heat pump can work, but what needs to change to make it work well: radiator sizes, pipework, controls and where the unit goes.
The survey in Maesteg includes a check of where the outdoor unit could sit and how its sound would reach neighbours. Houses in Maesteg built in different eras can need very different heat pump sizes, which is why each is calculated room by room.
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.
- Homes with an existing heat pump that seems undersized or expensive to run
- Homeowners planning insulation or building work who want to know the effect on heat demand
- Anyone getting a heat pump quote, as the first step
What's included
- Hot water cylinder sizing for your household
- Room-by-room heat loss calculation using the MCS method
- Outdoor unit siting options and noise check
- Radiator schedule with any upgrades needed for each room
- Electrical supply and network operator notes
Homeowners in Maesteg thinking about insulation work can use the survey to see how it would change their heat pump size.
Grants and rules for heat pumps in Wales
Homes in Maesteg 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.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Wales has its own permitted development rules for air source heat pumps, so we check what applies to your property, including listed building and conservation-area constraints, at the survey.

How long is the heating season in Maesteg?
On the shortest day Maesteg gets about 7 hours 48 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.

Heat loss surveys in Maesteg: questions
What size heat pump does a Maesteg 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 Maesteg home.
Where would the outdoor unit go on a Maesteg house?
Usually at the side or rear, on a level base with space around it for airflow and servicing, away from bedroom windows where possible. The surveyor checks positions at your Maesteg home.
How long does installation take in Maesteg?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Maesteg home states the expected time.
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.
What is a design flow temperature?
The design flow temperature is the temperature of the water sent to your radiators or underfloor heating on the coldest design day. Heat pumps are more efficient at lower flow temperatures, typically around 35–50°C. Choosing it is a balance: a lower figure improves efficiency but can mean larger radiators in some rooms, so the design shows both.
