We plan the whole change: the heat pump, cylinder and radiators, and what happens to the tank. Oil tanks are drained, cleaned and removed or made safe, and leased LPG tanks are usually collected by the supplier that owns them. Your quote sets out which parts are included and who arranges each one, so nothing is left loose at the end.
Owners across South Glamorgan can have oil tank removal arranged alongside a heat pump installation in South Glamorgan. Cottages and farmhouses in and around South Glamorgan often have solid walls, so the survey looks closely at construction and draughts. Rural properties near South Glamorgan usually have garden space for the outdoor unit, sited away from windows and sheltered where possible.
Who it suits
- Older oil boilers nearing the end of their life
- Eligible homes in England and Wales within the higher grant window
- Detached houses and bungalows with garden space for the unit
- Rural and village homes off the mains gas grid
Grants and rules for heat pumps in Wales
Homes in South Glamorgan can use the Boiler Upgrade Scheme, which applies in Wales as well as England: £7,500 towards an air source heat pump, or £9,000 when it replaces oil or LPG heating for installations from 21 July 2026 to 31 March 2027. The MCS-certified installer named in your quote applies and deducts the grant.
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.

Replacing an oil or LPG boiler with a heat pump questions
How much is the grant for replacing an oil boiler with a heat pump?
In England and Wales, the Boiler Upgrade Scheme grant is £9,000 when an air-to-water heat pump replaces oil or LPG heating, for installations from 21 July 2026 to 31 March 2027. Otherwise the standard £7,500 applies. The installer claims it and deducts it from your quote. Scotland's Home Energy Scotland funding works differently and includes extra for eligible rural homes; Northern Ireland has no dedicated homeowner scheme at present.
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.
What happens with a leased LPG tank?
Leased LPG tanks belong to the supplier, so the supplier arranges collection. Check your contract for notice periods and any charges before you fix a date. We time the switchover so you are not left without heating, and once the heat pump is commissioned the supplier can empty and remove the tank. Bottled LPG cylinders are simply returned.
