What to know about heat loss surveys in Llantrisant
A heat pump suits most Llantrisant homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
A surveyor visits your Llantrisant home to measure each room, window and wall before any heat pump is sized. Design outdoor temperatures for Llantrisant and the wider Mid Glamorgan 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
- Landlords comparing properties before deciding where to switch first
- Homeowners planning insulation or building work who want to know the effect on heat demand
What's included
- Outdoor unit siting options and noise check
- Written results in your quote, or a stand-alone report if you order one
- Recommended heat pump size and design flow temperature
- Radiator schedule with any upgrades needed for each room
- Electrical supply and network operator notes
Houses in Llantrisant built in different eras can need very different heat pump sizes, which is why each is calculated room by room.
Grants and rules for heat pumps in Wales
In Wales 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; £2,500 for air-to-air). The MCS-certified installer named in your quote applies to Ofgem for you, and the grant comes off your Llantrisant quote.
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.

Heat loss surveys in Llantrisant: questions
What size heat pump does a Llantrisant 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 Llantrisant home.
How soon can you survey a home in Llantrisant?
Survey dates depend on how busy installers are in Mid Glamorgan. We offer the next available dates when you enquire and confirm them in writing.
Where would the outdoor unit go on a Llantrisant 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 Llantrisant home.
Will the survey check noise from the outdoor unit?
Yes. The surveyor identifies possible positions for the outdoor unit and carries out the MCS noise assessment, which estimates the sound level at the nearest neighbouring window from the unit's sound power level, distance and any barriers. In England, meeting the MCS planning standards is one of the conditions for permitted development. Wales, Scotland and Northern Ireland have their own rules, which we check.
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.
