What to know about replacing an oil or LPG boiler with a heat pump in Tredegar
Every property in Tredegar 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.
Rural properties near Tredegar usually have garden space for the outdoor unit, sited away from windows and sheltered where possible. Cottages and farmhouses in and around Tredegar 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.
- Detached houses and bungalows with garden space for the unit
- Older oil boilers nearing the end of their life
- Rural and village homes off the mains gas grid
What's included
- Outdoor unit, heat pump cylinder, controls and radiator changes
- Network operator notification and electrical connection
- MCS certificate and grant application in England and Wales where eligible
- Oil tank draining and removal or making safe, as set out in your quote
- Help arranging LPG tank collection with your supplier
For homes outside Tredegar 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 Wales
Homes in Tredegar 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 in Tredegar: questions
How soon can you survey a home in Tredegar?
Survey dates depend on how busy installers are in Gwent. We offer the next available dates when you enquire and confirm them in writing.
Where would the outdoor unit go on a Tredegar 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 Tredegar home.
How long does installation take in Tredegar?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Tredegar home states the expected time.
Is a heat pump cheaper to run than oil?
It depends on oil prices, your home's insulation, the flow temperature and your electricity tariff, so there is no single answer. At the October to December 2026 price cap, a heat pump with a seasonal efficiency of 3.0 delivers heat for about 8.8p per kWh, and at 3.5 about 7.5p. Compare that with your oil cost per kWh of heat, allowing for your boiler's efficiency; the survey estimate gives a figure for your home.
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.
