Gas boiler to heat pump in Ashbourne: what to expect
Every property in Ashbourne is different, so the design starts from measurements rather than a rule of thumb. That keeps the system the right size and the running costs predictable.
Households across Derbyshire moving off gas can have a survey in Ashbourne that compares running costs on realistic assumptions. If your Ashbourne home still cooks on gas, we talk through whether to keep the supply or switch to an induction hob.
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.
- Boilers that are old, unreliable or due for replacement
- Combi owners who can find space for a hot water cylinder
- System or regular boiler homes with an existing airing cupboard
What's included
- Commissioning, MCS certificate and grant application in England and Wales where eligible
- Heat pump cylinder, outdoor unit and weather compensation controls
- Removal of the gas boiler, flue and any loft tanks
- Free survey with heat loss calculation and cylinder siting
- Capping of the gas pipe at the boiler position where you are giving up gas
Installers in Ashbourne take out the old boiler and flue and seal the wall opening as part of the job.
Grants and rules for heat pumps in England
Homes in Ashbourne can use the Boiler Upgrade Scheme, which takes £7,500 off the cost of an air source heat pump when it replaces fossil-fuel or electric heating. Replacing oil or LPG heating qualifies for £9,000 for installations from 21 July 2026 to 31 March 2027, and air-to-air systems for £2,500. The MCS-certified installer named in your quote applies for the grant and deducts it from the price.
There is no VAT on installing a heat pump anywhere in the UK until 31 March 2027. In England most houses can have an air source heat pump under permitted development, provided the unit meets the MCS noise and siting standards; the old 1 m boundary limit was removed on 29 May 2025. We flag listed buildings, flats and sensitive conservation-area positions at survey.

On the shortest day Ashbourne gets about 7 hours 33 minutes of daylight, with the noon sun around 14° up. The heating season runs from autumn into spring, so a heat pump that is sized correctly and set up with weather compensation does most of its work in steady, cool conditions.

Replacing a gas boiler with a heat pump in Ashbourne: questions
What size heat pump does an Ashbourne 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 Ashbourne home.
Can you service a heat pump in Ashbourne that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Ashbourne, whoever fitted them. Tell us the make and model when you book.
Where would the outdoor unit go on an Ashbourne 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 Ashbourne home.
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.
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.
