Before you book: heat loss surveys in Larne
Most homes can run on a heat pump if the system is designed properly, and Larne is no different. The key is matching the heat pump and radiators to the home's heat loss.
The survey in Larne includes a check of where the outdoor unit could sit and how its sound would reach neighbours. Houses in Larne 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.
- Self-builders and architects who need emitter and system sizes early
- Landlords comparing properties before deciding where to switch first
- Homes with an existing heat pump that seems undersized or expensive to run
What's included
- Electrical supply and network operator notes
- Radiator schedule with any upgrades needed for each room
- Hot water cylinder sizing for your household
- Recommended heat pump size and design flow temperature
- Outdoor unit siting options and noise check
Design outdoor temperatures for Larne and the wider County Antrim come from local cold-weather data, not a national average.
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 Larne.
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 Larne property at survey.
What to budget for heat loss surveys in Larne
Guide prices for Larne and the rest of County Antrim are shown below, installed and inc VAT. We publish ranges rather than a single figure because design details move the price, and the written quote after survey fixes it.
| 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.
Winter daylight and heating in Larne
On the shortest day Larne gets only about 7 hours 12 minutes of daylight and the noon sun sits around 12° above the horizon. Northern winters tend to be longer, so a well-designed, efficient system matters more here because it runs for more of the year.
How installation works in Larne
- Send your postcode and a few details, or use the guide price tool.
- A surveyor visits your Larne 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 Larne: questions
How soon can you survey a home in Larne?
Survey dates depend on how busy installers are in County Antrim. We offer the next available dates when you enquire and confirm them in writing.
Do you cover Carrickfergus as well as Larne?
Yes. We arrange surveys and installation in Carrickfergus, which is about 9 miles south of Larne, and across County Antrim.
Do I need new radiators for a heat pump in Larne?
Often some, not all. Heat pumps run best at lower water temperatures, so rooms with small radiators may need larger ones. The survey of your Larne home gives a room-by-room list.
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.
Will the survey check noise from the outdoor unit?
Yes. The surveyor identifies possible positions for the outdoor unit and carries out the MCS noise assessment, which estimates the sound level at the nearest neighbouring window from the unit's sound power level, distance and any barriers. In England, meeting the MCS planning standards is one of the conditions for permitted development. Wales, Scotland and Northern Ireland have their own rules, which we check.
