What to know about heat loss surveys in Ballynahinch
The question for a Ballynahinch 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.
Design outdoor temperatures for Ballynahinch and the wider County Down come from local cold-weather data, not a national average. For Ballynahinch 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.
- Anyone getting a heat pump quote, as the first step
- Homeowners planning insulation or building work who want to know the effect on heat demand
- Self-builders and architects who need emitter and system sizes early
What's included
- Electrical supply and network operator notes
- 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
Houses in Ballynahinch 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 Northern Ireland
Northern Ireland does not have a dedicated heat pump grant for homeowners at present, and the Boiler Upgrade Scheme does not apply here. Heat pumps have sometimes been funded through the Northern Ireland Sustainable Energy Programme, so it is worth checking what is open when you enquire about a home in Ballynahinch.
Installing heat pumps has been zero-rated for VAT in Northern Ireland since 1 May 2023, in line with the rest of the UK, until 31 March 2027. Northern Ireland has its own permitted development rules and building regulations, and we confirm what applies to your Ballynahinch property at survey.

Heat loss surveys in Ballynahinch: questions
What size heat pump does a Ballynahinch 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 Ballynahinch home.
How long does a heat pump survey take in Ballynahinch?
A home survey in Ballynahinch 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.
Can you service a heat pump in Ballynahinch that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Ballynahinch, whoever fitted them. Tell us the make and model when you book.
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.
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.
