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

A heat pump suits most Dumfries homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.

If your Dumfries home still cooks on gas, we talk through whether to keep the supply or switch to an induction hob. Households across Dumfries and Galloway moving off gas can have a survey in Dumfries that compares running costs on realistic assumptions.

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

  • Free survey with heat loss calculation and cylinder siting
  • Removal of the gas boiler, flue and any loft tanks
  • 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
  • Heat pump cylinder, outdoor unit and weather compensation controls

Rear gardens and side returns in Dumfries usually offer a sensible spot for the outdoor unit, checked for airflow and neighbours.

Grants and rules for heat pumps in Scotland

Scotland

In Scotland, heat pump funding comes through Home Energy Scotland rather than the Boiler Upgrade Scheme: a grant of up to £7,500 (up to £1,500 extra for eligible rural and island homes) and an optional interest-free loan of up to £7,500. For a Dumfries home, apply and receive the written offer before the installation date is fixed.

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 Dumfries property at survey.

On the shortest day Dumfries gets only about 7 hours 09 minutes of daylight and the noon sun sits around 11° 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.

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

What size heat pump does a Dumfries 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 Dumfries home.

How soon can you survey a home in Dumfries?

Survey dates depend on how busy installers are in Dumfries and Galloway. We offer the next available dates when you enquire and confirm them in writing.

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

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

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.

Can a heat pump replace a combi boiler?

Yes, but you need room for a hot water cylinder, because heat pumps store hot water rather than heating it on demand. Most homes find a space in a cupboard, utility room, garage or under the stairs, and compact or combined indoor units help where space is tight. The survey measures the options first, so you know where everything will go before you accept the quote.
