Before you book: replacing a gas boiler with a heat pump in Cramlington
Most homes can run on a heat pump if the system is designed properly, and Cramlington is no different. The key is matching the heat pump and radiators to the home's heat loss.
Rear gardens and side returns in Cramlington usually offer a sensible spot for the outdoor unit, checked for airflow and neighbours. Households across Northumberland moving off gas can have a survey in Cramlington 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.
- Households ready to give up gas entirely and drop the standing charge
- Boilers that are old, unreliable or due for replacement
- Combi owners who can find space for a hot water cylinder
What's included
- Removal of the gas boiler, flue and any loft tanks
- Commissioning, MCS certificate and grant application in England and Wales where eligible
- Heat pump cylinder, outdoor unit and weather compensation controls
- 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 Cramlington 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
In England the Boiler Upgrade Scheme gives £7,500 towards an air source heat pump (£9,000 if it replaces oil or LPG, from 21 July 2026 to 31 March 2027), and since 28 April 2026 a valid EPC is no longer needed. The grant is applied for by the MCS-certified installer and shown as a deduction on your Cramlington quote.
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.

Short winter days in Cramlington and what they mean
On the shortest day Cramlington 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.
The steps for replacing a gas boiler with a heat pump in Cramlington
- Send your postcode and a few details, or use the guide price tool.
- A surveyor visits your Cramlington home, measures every room and checks where the outdoor unit can go.
- You receive a heat loss design and a fixed written quote, with any grant shown where it applies.
- Installers fit the unit, cylinder and any radiator changes, typically over 2–4 days on site.
- The system is commissioned, set up with weather compensation and handed over with the paperwork.
Replacing a gas boiler with a heat pump in Cramlington: questions
How soon can you survey a home in Cramlington?
Survey dates depend on how busy installers are in Northumberland. We offer the next available dates when you enquire and confirm them in writing.
How long does installation take in Cramlington?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Cramlington home states the expected time.
What size heat pump does a Cramlington 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 Cramlington 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.
