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

In Aldershot, as anywhere in the UK, the heat pumps that perform well are the ones designed around low flow temperatures and sized from a proper heat loss calculation.

Rear gardens and side returns in Aldershot usually offer a sensible spot for the outdoor unit, checked for airflow and neighbours. Many gas-heated homes in Aldershot have a combi boiler in the kitchen, so the survey starts by finding the right place for a 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.

  • Homes in England and Wales eligible for the Boiler Upgrade Scheme
  • Combi owners who can find space for a hot water cylinder
  • Households ready to give up gas entirely and drop the standing charge

What's included

  • Free survey with heat loss calculation and cylinder siting
  • Removal of the gas boiler, flue and any loft tanks
  • 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
  • Commissioning, MCS certificate and grant application in England and Wales where eligible

Households across Hampshire moving off gas can have a survey in Aldershot that compares running costs on realistic assumptions.

Grants and rules for heat pumps in England

England

Homes in Aldershot 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 Aldershot gets about 7 hours 52 minutes of daylight, and the winter sun reaches only around 15° above the horizon at noon. Winters this far south are milder than in most of the UK, which helps a heat pump run at low flow temperatures for much of the season.

The steps for replacing a gas boiler with a heat pump in Aldershot

  1. Send your postcode and a few details, or use the guide price tool.
  2. A surveyor visits your Aldershot home, measures every room and checks where the outdoor unit can go.
  3. You receive a heat loss design and a fixed written quote, with any grant shown where it applies.
  4. Installers fit the unit, cylinder and any radiator changes, typically over 2–4 days on site.
  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 Aldershot: questions

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

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

Do you cover Farnborough as well as Aldershot?

Yes. We arrange surveys and installation in Farnborough, which is about 3 miles north of Aldershot, and across Hampshire.

How soon can you survey a home in Aldershot?

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

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.
