Before you book: heat loss surveys in Renfrew
Most homes can run on a heat pump if the system is designed properly, and Renfrew is no different. The key is matching the heat pump and radiators to the home's heat loss.
Homeowners in Renfrew thinking about insulation work can use the survey to see how it would change their heat pump size. Houses in Renfrew 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
- Self-builders and architects who need emitter and system sizes early
- Anyone getting a heat pump quote, as the first step
What's included
- Hot water cylinder sizing for your household
- Electrical supply and network operator notes
- Outdoor unit siting options and noise check
- Radiator schedule with any upgrades needed for each room
- Room-by-room heat loss calculation using the MCS method
A surveyor visits your Renfrew home to measure each room, window and wall before any heat pump is sized.
Grants and rules for heat pumps in Scotland
In Scotland, heat pump funding comes through Home Energy Scotland rather than the Boiler Upgrade Scheme: a grant of up to £7,500 (up to £1,500 extra for eligible rural and island homes) and an optional interest-free loan of up to £7,500. For a Renfrew home, apply and receive the written offer before the installation date is fixed.
There is no VAT on installing a heat pump anywhere in the UK, Scotland included, until 31 March 2027. Scottish permitted development rules and building standards apply, and the surveyor checks the unit position and any listed or conservation-area constraints.
What to budget for heat loss surveys in Renfrew
The ranges below are typical installed prices for homes in Renfrewshire and Inverclyde, including VAT. A survey sets the exact figure, because two similar-looking houses in Renfrew can need quite different radiators and pipework.
| Survey | Guide price |
|---|---|
| Home survey and heat loss calculation with an installation quote | Free |
| Stand-alone heat loss survey and report | £150–£400 |
Inc VAT. A stand-alone report is for homeowners who want the design without an installation quote.
Designing for Renfrew's winters
Renfrew has about 6 hours 58 minutes of daylight at midwinter against 17 hours 35 minutes in midsummer. Heat pumps are designed to keep working well below freezing, but the design temperature for the survey is set for local conditions, not an average day.

Heat loss surveys in Renfrew: questions
What size heat pump does a Renfrew 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 Renfrew home.
How long does a heat pump survey take in Renfrew?
A home survey in Renfrew 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.
Do you cover Erskine as well as Renfrew?
Yes. We arrange surveys and installation in Erskine, which is about 3 miles north-west of Renfrew, and across Renfrewshire and Inverclyde.
Why can't you size the heat pump from my boiler?
Boilers are often much larger than a home's real heat loss, because they are sized for fast hot water and quick warm-ups. Matching a heat pump to the boiler's output usually means an oversized unit that costs more and switches on and off too often. A room-by-room calculation finds the actual heat demand, which is what the heat pump needs to meet.
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.
