What to know about replacing a gas boiler with a heat pump in Stirling

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

Many gas-heated homes in Stirling have a combi boiler in the kitchen, so the survey starts by finding the right place for a cylinder. Semi-detached and terraced houses in Stirling often have an airing cupboard that can be reused for a heat pump cylinder.

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.

  • System or regular boiler homes with an existing airing cupboard
  • Combi owners who can find space for a hot water cylinder
  • Boilers that are old, unreliable or due for replacement

What's included

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

If your Stirling home still cooks on gas, we talk through whether to keep the supply or switch to an induction hob.

Grants and rules for heat pumps in Scotland

Scotland

The Boiler Upgrade Scheme does not apply in Scotland. Instead, homeowners in Stirling 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.

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.

  5. The system is commissioned, set up with weather compensation and handed over with the paperwork.

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

How soon can you survey a home in Stirling?

Survey dates depend on how busy installers are in Stirling, Falkirk and Clackmannanshire. We offer the next available dates when you enquire and confirm them in writing.

What size heat pump does a Stirling 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 Stirling home.

Do I need new radiators for a heat pump in Stirling?

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 Stirling home gives a room-by-room list.

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.

Do I need to replace the cylinder I already have?

Usually, yes. Older cylinders have a small internal coil designed for water from a boiler at around 60–70°C, and they cannot take in heat quickly enough at the lower temperatures a heat pump runs at. A heat pump cylinder has a larger coil. On its own, a cylinder supplied and fitted has a guide price of £1,200–£2,200, installed and including VAT, though it is normally part of the full system price.
