Gas boiler to heat pump in Desborough: what to expect
Every property in Desborough 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 Northamptonshire moving off gas can have a survey in Desborough that compares running costs on realistic assumptions. Many gas-heated homes in Desborough 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
- Boilers that are old, unreliable or due for replacement
- Combi owners who can find space for a hot water cylinder
What's included
- Commissioning, MCS certificate and grant application in England and Wales where eligible
- Removal of the gas boiler, flue and any loft tanks
- Free survey with heat loss calculation and cylinder siting
- Heat pump cylinder, outdoor unit and weather compensation controls
- System flush and radiator upgrades where the design calls for them
If your Desborough 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 England
Homes in Desborough 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.

Winter daylight and heating in Desborough
Desborough has about 7 hours 40 minutes of daylight at midwinter and 16 hours 49 minutes at midsummer. That swing matters if you pair a heat pump with solar panels: summer generation can cover much of the hot water, winter generation far less.

Replacing a gas boiler with a heat pump in Desborough: questions
How soon can you survey a home in Desborough?
Survey dates depend on how busy installers are in Northamptonshire. We offer the next available dates when you enquire and confirm them in writing.
Do you cover Kettering as well as Desborough?
Yes. We arrange surveys and installation in Kettering, which is about 5 miles south-east of Desborough, and across Northamptonshire.
Where would the outdoor unit go on a Desborough 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 Desborough 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.
