Before you book: replacing a gas boiler with a heat pump in Irvine

Most homes can run on a heat pump if the system is designed properly, and Irvine is no different. The key is matching the heat pump and radiators to the home's heat loss.

Households across Ayrshire moving off gas can have a survey in Irvine that compares running costs on realistic assumptions. Rear gardens and side returns in Irvine usually offer a sensible spot for the outdoor unit, checked for airflow and neighbours.

Moving from mains gas to a heat pump means finding cylinder space, deciding what happens to the gas supply and comparing running costs on realistic assumptions.

  • Households ready to give up gas entirely and drop the standing charge
  • Boilers that are old, unreliable or due for replacement
  • System or regular boiler homes with an existing airing cupboard

What's included

  • Free survey with heat loss calculation and cylinder siting
  • Heat pump cylinder, outdoor unit and weather compensation controls
  • Capping of the gas pipe at the boiler position where you are giving up gas
  • System flush and radiator upgrades where the design calls for them
  • Removal of the gas boiler, flue and any loft tanks

Installers in Irvine take out the old boiler and flue and seal the wall opening as part of the job.

Grants and rules for heat pumps in Scotland

Scotland

The Boiler Upgrade Scheme does not apply in Scotland. Instead, homeowners in Irvine can apply to Home Energy Scotland for a grant of up to £7,500 towards a heat pump, with up to £1,500 more for eligible rural and island homes, plus an optional interest-free loan of up to £7,500. You need a written funding offer before any work starts.

Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Scotland has its own permitted development rules for air source heat pumps and its own building standards, so we confirm what applies to your Irvine property at survey.

What to budget for replacing a gas boiler with a heat pump in Irvine

These are guide prices for Ayrshire, installed and including VAT. Your final price is fixed in a written quote after the survey and depends on the heat loss of the house, the radiators that need changing and where the unit goes.

On the shortest day Irvine gets only about 7 hours 02 minutes of daylight, with the sun around 11° up at noon. Long Scottish winters mean the heat pump runs for much of the year, so careful sizing, good controls and correctly sized radiators make a real difference.

Replacing a gas boiler with a heat pump in Irvine: questions

Where would the outdoor unit go on an Irvine 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 Irvine home.

Can you service a heat pump in Irvine that someone else installed?

Yes. We arrange servicing and repairs for most air source heat pumps in Irvine, whoever fitted them. Tell us the make and model when you book.

What size heat pump does an Irvine 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 Irvine home.

Should I have my gas meter removed?

If gas is used for nothing else, removing the meter ends the gas standing charge, which is about £108 a year at the October to December 2026 price cap. If you still cook on gas or have a gas fire, you will need to keep the supply. Meter removal is arranged through your gas supplier, usually once the heat pump is running; the pipe at the boiler position is capped during the installation.

Will my hot water run out with a heat pump?

Not if the cylinder is sized properly for your household. The survey asks how many people live in the home, how many bathrooms you have and whether you prefer baths or showers, then sizes the cylinder to suit. The heat pump reheats the cylinder on a schedule, often overnight and again during the day, and an immersion heater acts as a backup.
