Before you book: replacing an oil or LPG boiler with a heat pump in Newcastle
In Newcastle, 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.
Cottages and farmhouses in and around Newcastle often have solid walls, so the survey looks closely at construction and draughts. Rural properties near Newcastle usually have garden space for the outdoor unit, sited away from windows and sheltered where possible.
Off-gas homes have a lot to plan when switching to a heat pump: the fuel tank, older walls, rural power supplies and higher heat loss.
- Detached houses and bungalows with garden space for the unit
- Owners tired of fuel deliveries and tank maintenance
- Rural and village homes off the mains gas grid
What's included
- Oil tank draining and removal or making safe, as set out in your quote
- Removal of the oil or LPG boiler and flue
- Help arranging LPG tank collection with your supplier
- Outdoor unit, heat pump cylinder, controls and radiator changes
- Network operator notification and electrical connection
For homes outside Newcastle reached by a long drive or narrow lane, delivery of the unit and cylinder is planned in advance.
Grants and rules for heat pumps in Northern Ireland
The Boiler Upgrade Scheme covers England and Wales only, and there is currently no dedicated heat pump grant for homeowners in Northern Ireland. Our quote for a Newcastle home is therefore shown without a grant deduction; if support becomes available we will tell you how it applies.
There is no VAT on installing a heat pump in Northern Ireland until 31 March 2027, the same as in Great Britain. Planning and building control here follow Northern Ireland's own rules, so the survey checks the unit position against them.

Designing for Newcastle's winters
Newcastle sees roughly 7 hours 20 minutes of daylight in December and 17 hours 12 minutes in June. With a longer heating season than the south, the gains from low flow temperatures and good controls add up over the year.
The steps for replacing an oil or LPG boiler with a heat pump in Newcastle
- Send your postcode and a few details, or use the guide price tool.
- A surveyor visits your Newcastle 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 an oil or LPG boiler with a heat pump in Newcastle: questions
How long does installation take in Newcastle?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Newcastle home states the expected time.
What size heat pump does a Newcastle 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 Newcastle home.
Can you service a heat pump in Newcastle that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Newcastle, whoever fitted them. Tell us the make and model when you book.
Can a heat pump cope with an exposed rural spot?
Yes. Air source heat pumps are designed to keep working well below freezing, and they periodically defrost, giving off a little vapour, which is normal. In exposed locations the installer chooses a sheltered position where possible, raises the unit to clear snow and let defrost water drain, and sizes the system for the local winter design temperature used in the heat loss calculation.
Do I have to remove my oil tank?
Not always, but it should be emptied and made safe. A tank in good condition can be drained, cleaned and left in place, though most owners prefer to have it taken away to free up space. Old or damaged tanks are usually removed. Your quote says which option is included, and any remaining oil and sludge is disposed of properly.
