What to know about heat loss surveys in Mold
Homes around Mold range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
Homeowners in Mold thinking about insulation work can use the survey to see how it would change their heat pump size. A surveyor visits your Mold home to measure each room, window and wall before any heat pump is sized.
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
- Homeowners planning insulation or building work who want to know the effect on heat demand
- Homes with an existing heat pump that seems undersized or expensive to run
What's included
- Electrical supply and network operator notes
- Outdoor unit siting options and noise check
- Hot water cylinder sizing for your household
- Recommended heat pump size and design flow temperature
- Radiator schedule with any upgrades needed for each room
Houses in Mold 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 Mold 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.

Inc VAT. A stand-alone report is for homeowners who want the design without an installation quote.
Designing for Mold's winters
Mold has about 7 hours 32 minutes of daylight at midwinter and 16 hours 58 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.
The steps for heat loss surveys in Mold
- Send your postcode and a few details, or use the guide price tool.
- A surveyor visits your Mold home, measures every room and checks where the outdoor unit can go.
- You receive a heat loss design and a fixed written quote, with any grant shown where it applies.
- Installers fit the unit, cylinder and any radiator changes, typically over 2–4 days on site.
- The system is commissioned, set up with weather compensation and handed over with the paperwork.
Heat loss surveys in Mold: questions
How long does installation take in Mold?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Mold home states the expected time.
How soon can you survey a home in Mold?
Survey dates depend on how busy installers are in Clwyd. We offer the next available dates when you enquire and confirm them in writing.
Where would the outdoor unit go on a Mold 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 Mold home.
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.
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.
