What to know about heat loss surveys in Tenby
In Tenby, as anywhere in the UK, the heat pumps that perform well are the ones designed around low flow temperatures and sized from a proper heat loss calculation.
Homeowners in Tenby thinking about insulation work can use the survey to see how it would change their heat pump size. For Tenby homes with extensions or loft conversions, each part of the house is assessed on its own construction.
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.
- Landlords comparing properties before deciding where to switch first
- Anyone getting a heat pump quote, as the first step
- Homes with an existing heat pump that seems undersized or expensive to run
What's included
- Room-by-room heat loss calculation using the MCS method
- Hot water cylinder sizing for your household
- Outdoor unit siting options and noise check
- Electrical supply and network operator notes
- Recommended heat pump size and design flow temperature
A surveyor visits your Tenby home to measure each room, window and wall before any heat pump is sized.
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 Tenby quote.
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.

Inc VAT. A stand-alone report is for homeowners who want the design without an installation quote.
Designing for Tenby's winters
Tenby has about 7 hours 48 minutes of daylight at midwinter and 16 hours 40 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.

Heat loss surveys in Tenby: questions
Can you service a heat pump in Tenby that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Tenby, whoever fitted them. Tell us the make and model when you book.
How long does a heat pump survey take in Tenby?
A home survey in Tenby 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.
How soon can you survey a home in Tenby?
Survey dates depend on how busy installers are in Dyfed. We offer the next available dates when you enquire and confirm them in writing.
Can I use the heat loss report to get other quotes?
Yes. A stand-alone heat loss report is yours to use, including sharing it with other installers so their quotes are based on the same figures. Comparing quotes like for like makes it easier to see differences in equipment, radiator upgrades and workmanship terms. The report states the assumptions used wherever construction could not be confirmed.
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.
