Before you book: replacing an oil or LPG boiler with a heat pump in Berkhamsted
Every property in Berkhamsted 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.
If your home near Berkhamsted is off the mains gas grid, a heat pump removes the need for oil or LPG deliveries. Rural properties near Berkhamsted 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.
- Older oil boilers nearing the end of their life
- Rural and village homes off the mains gas grid
- Owners tired of fuel deliveries and tank maintenance
What's included
- Help arranging LPG tank collection with your supplier
- Network operator notification and electrical connection
- MCS certificate and grant application in England and Wales where eligible
- Removal of the oil or LPG boiler and flue
- Outdoor unit, heat pump cylinder, controls and radiator changes
Cottages and farmhouses in and around Berkhamsted often have solid walls, so the survey looks closely at construction and draughts.
Grants and rules for heat pumps in England
Homes in Berkhamsted can use the Boiler Upgrade Scheme, which takes £7,500 off the cost of an air source heat pump when it replaces fossil-fuel or electric heating. Replacing oil or LPG heating qualifies for £9,000 for installations from 21 July 2026 to 31 March 2027, and air-to-air systems for £2,500. The MCS-certified installer named in your quote applies for the grant and deducts it from the price.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Since 29 May 2025, permitted development in England allows up to two air source heat pumps on a house, each up to 1.5 m³, with no blanket 1 m boundary rule — the installation must still meet the MCS planning standards, including the noise check. Listed buildings, flats and some conservation-area positions need extra consent, which we check at survey.

Replacing an oil or LPG boiler with a heat pump in Berkhamsted: questions
Do you cover Tring as well as Berkhamsted?
Yes. We arrange surveys and installation in Tring, which is about 5 miles north-west of Berkhamsted, and across Hertfordshire.
Can you service a heat pump in Berkhamsted that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Berkhamsted, whoever fitted them. Tell us the make and model when you book.
How long does a heat pump survey take in Berkhamsted?
A home survey in Berkhamsted usually takes one to two hours. The surveyor measures every heated room, checks windows, walls and radiators, and looks at where the outdoor unit and cylinder can go.
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.
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.
