Heat loss survey for Coleraine homes
The question for a Coleraine 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.
For Coleraine homes with extensions or loft conversions, each part of the house is assessed on its own construction. The survey in Coleraine includes a check of where the outdoor unit could sit and how its sound would reach neighbours.
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
- 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
- Written results in your quote, or a stand-alone report if you order one
- Room-by-room heat loss calculation using the MCS method
- Hot water cylinder sizing for your household
- Radiator schedule with any upgrades needed for each room
- Recommended heat pump size and design flow temperature
Houses in Coleraine 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
The Boiler Upgrade Scheme covers England and Wales only, and there is currently no dedicated heat pump grant for homeowners in Northern Ireland. Our quote for a Coleraine home is therefore shown without a grant deduction; if support becomes available we will tell you how it applies.
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 Coleraine property at survey.
What to budget for heat loss surveys in Coleraine
The ranges below are typical installed prices for homes in County Londonderry, including VAT. A survey sets the exact figure, because two similar-looking houses in Coleraine 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–£390 |
Inc VAT. A stand-alone report is for homeowners who want the design without an installation quote.
How long is the heating season in Coleraine?
Coleraine sees roughly 7 hours 08 minutes of daylight in December and 17 hours 24 minutes in June. With a longer heating season than the south, the gains from low flow temperatures and good controls add up over the year.
What happens after you enquire in Coleraine?
- Send your postcode and a few details, or use the guide price tool.
- A surveyor visits your Coleraine 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 Coleraine: questions
What size heat pump does a Coleraine 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 Coleraine home.
Where would the outdoor unit go on a Coleraine 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 Coleraine home.
How soon can you survey a home in Coleraine?
Survey dates depend on how busy installers are in County Londonderry. We offer the next available dates when you enquire and confirm them in writing.
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.
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.
