Oil and LPG boiler replacement for Blackwood homes
A heat pump suits most Blackwood homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
Owners across Gwent can have oil tank removal arranged alongside a heat pump installation in Blackwood. Cottages and farmhouses in and around Blackwood often have solid walls, so the survey looks closely at construction and draughts.
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.
- Older oil boilers nearing the end of their life
- Detached houses and bungalows with garden space for the unit
- Owners tired of fuel deliveries and tank maintenance
What's included
- Outdoor unit, heat pump cylinder, controls and radiator changes
- Free survey with a detailed heat loss calculation for older construction
- Help arranging LPG tank collection with your supplier
- Network operator notification and electrical connection
- Oil tank draining and removal or making safe, as set out in your quote
Bungalows and detached houses near Blackwood running on LPG can move to a heat pump, with the tank collected by the supplier.
Grants and rules for heat pumps in Wales
In Wales 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; £2,500 for air-to-air). The MCS-certified installer named in your quote applies to Ofgem for you, and the grant comes off your Blackwood quote.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Wales has its own permitted development rules for air source heat pumps, so we check what applies to your property, including listed building and conservation-area constraints, at the survey.

Installed, inc VAT: unit, cylinder, controls, minor pipework and commissioning. The £9,000 Boiler Upgrade Scheme figure applies to oil and LPG replacements in England and Wales installed from 21 July 2026 to 31 March 2027.
How long is the heating season in Blackwood?
Blackwood has about 7 hours 48 minutes of daylight at midwinter and 16 hours 40 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 an oil or LPG boiler with a heat pump in Blackwood: questions
Can you service a heat pump in Blackwood that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Blackwood, whoever fitted them. Tell us the make and model when you book.
How soon can you survey a home in Blackwood?
Survey dates depend on how busy installers are in Gwent. We offer the next available dates when you enquire and confirm them in writing.
Do I need new radiators for a heat pump in Blackwood?
Often some, not all. Heat pumps run best at lower water temperatures, so rooms with small radiators may need larger ones. The survey of your Blackwood home gives a room-by-room list.
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.
Will I need bigger radiators in an older cottage or farmhouse?
Often in some rooms, because thick solid walls and older windows lose more heat, and heat pumps work at lower water temperatures than oil boilers. The survey checks each room. Rooms with high ceilings or large windows are common candidates for a larger radiator. Where swapping radiators is impractical, a high-temperature unit can be considered, with lower efficiency as the trade-off.
