Oil and LPG boiler replacement in Amesbury: what to expect
Homes around Amesbury range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
Cottages and farmhouses in and around Amesbury often have solid walls, so the survey looks closely at construction and draughts. Bungalows and detached houses near Amesbury running on LPG can move to a heat pump, with the tank collected by the supplier.
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
- Detached houses and bungalows with garden space for the unit
What's included
- Free survey with a detailed heat loss calculation for older construction
- Network operator notification and electrical connection
- Outdoor unit, heat pump cylinder, controls and radiator changes
- Oil tank draining and removal or making safe, as set out in your quote
- MCS certificate and grant application in England and Wales where eligible
For homes outside Amesbury 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 England
In England 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), and since 28 April 2026 a valid EPC is no longer needed. The grant is applied for by the MCS-certified installer and shown as a deduction on your Amesbury quote.
There is no VAT on installing a heat pump anywhere in the UK until 31 March 2027. In England most houses can have an air source heat pump under permitted development, provided the unit meets the MCS noise and siting standards; the old 1 m boundary limit was removed on 29 May 2025. We flag listed buildings, flats and sensitive conservation-area positions at survey.

Designing for Amesbury's winters
Amesbury sees roughly 7 hours 53 minutes of daylight in late December against 16 hours 35 minutes in June. Milder southern winters suit heat pumps well, though the system is still sized for a cold snap rather than an average day.

Replacing an oil or LPG boiler with a heat pump in Amesbury: questions
Do you cover Salisbury as well as Amesbury?
Yes. We arrange surveys and installation in Salisbury, which is about 7 miles south of Amesbury, and across Wiltshire.
How soon can you survey a home in Amesbury?
Survey dates depend on how busy installers are in Wiltshire. We offer the next available dates when you enquire and confirm them in writing.
Do I need new radiators for a heat pump in Amesbury?
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 Amesbury home gives a room-by-room list.
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.
