What to know about replacing an oil or LPG boiler with a heat pump in Pembroke Dock
Every property in Pembroke Dock 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.
For homes outside Pembroke Dock reached by a long drive or narrow lane, delivery of the unit and cylinder is planned in advance. Cottages and farmhouses in and around Pembroke Dock 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
- Rural and village homes off the mains gas grid
What's included
- MCS certificate and grant application in England and Wales where eligible
- Network operator notification and electrical connection
- Outdoor unit, heat pump cylinder, controls and radiator changes
- Help arranging LPG tank collection with your supplier
- Removal of the oil or LPG boiler and flue
Rural properties near Pembroke Dock usually have garden space for the outdoor unit, sited away from windows and sheltered where possible.
Grants and rules for heat pumps in Wales
Homes in Pembroke Dock 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.

Short winter days in Pembroke Dock and what they mean

Replacing an oil or LPG boiler with a heat pump in Pembroke Dock: questions
Where would the outdoor unit go on a Pembroke Dock 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 Pembroke Dock home.
How long does installation take in Pembroke Dock?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Pembroke Dock home states the expected time.
How soon can you survey a home in Pembroke Dock?
Survey dates depend on how busy installers are in Dyfed. We offer the next available dates when you enquire and confirm them in writing.
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.
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.
