Replace an Oil or LPG Boiler with an Air Source Heat Pump in Royal Wootton Bassett, SW
Off the gas grid around Royal Wootton Bassett? Oil and LPG households are exactly who the Boiler Upgrade Scheme uplift is for: from 21 July 2026 the grant rises to £9,000 (from £7,500) for homes heated by oil or LPG, expected to run to around March 2027. A heat pump replaces the tank, the deliveries and the price swings, and most oil-heated homes already have the radiators and cylinder a heat pump needs.
The heating picture in South West England
Most homes here heat with a mains-gas boiler, and the Ofgem price cap gas rate jumps 27% on 1 July 2026 (5.74p to 7.33p/kWh). With £7,500 off through the Boiler Upgrade Scheme and 0% VAT until March 2027, replacing the boiler with an air source heat pump at end-of-life is now cost-competitive up front and on running costs. The South West has the highest share of oil-heated homes in England - prime territory for the £9,000 oil/LPG uplift from 21 July 2026.

A 90%-efficient boiler and a heat pump at SCOP 3.8-4.5 are assumed; heating oil is an editorial estimate. Standing charges excluded unless noted. Installed prices are indicative, June 2026, with 0% VAT already applied. Actual costs depend on your tariff, home and usage.
The £9,000 oil and LPG uplift
From 21 July 2026 the Boiler Upgrade Scheme pays £9,000 (up from £7,500) toward an air source heat pump for homes heated by oil or LPG, expected to run to around March 2027. That makes off-gas homes the best-supported switchers in the country for that window. Practical advantages stack on top:
- No more deliveries to schedule or tank levels to watch
- Most oil-heated homes already have radiators and a cylinder, which keeps the conversion scope down
- Rural installers like Grant's network specialise in exactly this retrofit
How to Switch from a Oil or LPG Boiler to an Air Source Heat Pump in Royal Wootton Bassett
Get a heat-loss survey
A local installer visits your Royal Wootton Bassett home and calculates heat loss room by room (an MCS requirement). Oil-heated homes usually already have radiators and a cylinder, which the survey checks for compatibility with lower flow temperatures.
Choose your unit and confirm the quote
Grant Aerona3 is the established oil-belt favourite and every other UK-market brand also handles rural retrofits; ask for low-temperature output figures. The quote should cover decommissioning the oil or LPG boiler and dealing with the tank.
Let your installer claim the £7,500 grant
The Boiler Upgrade Scheme requires an MCS-certified installer, who applies on your behalf so the £7,500 comes straight off the quote (£9,000 for oil and LPG heated homes from 21 July 2026). You never front the grant money. The EPC precondition was removed in April 2026.
Installation and tank decommissioning
The heat pump, cylinder (if yours needs upgrading) and controls go in, the system is commissioned, and the oil or LPG boiler is decommissioned. Tank removal or decommissioning is agreed in the quote. Any gas work on an LPG system must be done by a Gas Safe registered engineer.

0% VAT on heat pump, solar and battery installations
Residential installations of heat pumps, solar panels and home batteries are zero-rated for VAT until 31 March 2027 (then 5%). Applied automatically by the installer - typically worth £1,000-3,000 on a heat pump job versus standard 20% VAT.
What happens to my old oil or LPG boiler and tank?
Your installer decommissions the boiler and agrees what happens to the tank: removal, or draining and decommissioning in place. Any work on an LPG gas system must be done by a Gas Safe registered engineer. From then on there are no deliveries to schedule, no tank to maintain, and no exposure to oil price swings; your heating runs on electricity at a SCOP of roughly 3.8 to 4.5.
