Heat Your Home With Oil or LPG? Your Grant Rises to £9,000 on 21 July 2026
The government is raising the Boiler Upgrade Scheme grant from £7,500 to £9,000 for homes that heat with oil or LPG. It's temporary — the higher amount is expected to run until 31 March 2027 — and it comes straight off your installation invoice. You don't fill in any forms: as your MCS-certified installer, we apply on your behalf and you simply pay the reduced price.
See If You QualifyWhat We Install
Oil & LPG Boiler Replacement
Built for off-gas-grid village homes: boiler and tank decommissioning, system conversion, and the £9,000 grant applied upfront.
Air-to-Air Heat Pumps
Warm in winter, cool in summer, from discreet wall units — with £2,500 Boiler Upgrade Scheme support where eligible.
Why Oil-Heated Homes in Bucks Are Switching
Heating oil isn't covered by the energy price cap, tanks need topping up before winter, and prices spike exactly when you need heat most. A heat pump delivers three to four units of heat for every unit of electricity it uses — and for oil and LPG homes the grant is at its highest.
| System | Energy used | Cost per year |
|---|---|---|
| Oil boiler (85% efficient) | 2,270 L @ 60p/L | ~£1,360 |
| Air source heat pump (SCOP 3.5) | 5,715 kWh @ 18p/kWh* | ~£1,030 |
| Difference | — | ~£330/yr saved |

Where We Work
We install across Aylesbury, Buckingham, Wendover, Princes Risborough, Winslow and the rural villages of North Buckinghamshire — the oil and LPG heartland, where off-gas-grid homes qualify for the largest grants and see the biggest running-cost savings. If you're anywhere in the Vale or within a sensible drive of it, we cover you.
Common Questions
Do I qualify for the £9,000 grant?
If you own your home in England or Wales, currently heat it with oil or LPG, and have a valid EPC with no outstanding loft or cavity wall insulation recommendations, you're very likely to qualify from 21 July 2026. Gas-heated homes qualify for £7,500. We confirm eligibility at the survey and make the application for you — full detail in our £9,000 grant guide.
Will a heat pump really be cheaper to run than my oil boiler?
For most oil and LPG homes, yes — a well-designed system typically costs less to run, and unlike oil you're protected from winter price spikes and tank top-ups. The honest answer depends on your tariff and how well the system is designed, which is why we publish our workings in the running costs guide and size everything from a real heat loss survey.
Do I need planning permission? What about noise?
Almost never. Since May 2025 the old one-metre boundary rule is gone in England — most installations are permitted development, provided the unit passes the MCS noise assessment and stays within size limits. Modern units are about as loud as a fridge from a few metres away. See the planning and noise guide for the rules in full.
My house is listed or in a conservation area — can I still have one?
Usually, with the right siting and sometimes listed building consent for the outdoor unit. North Bucks is full of period homes and we design for them: discreet positioning, acoustic screening, and high-temperature heat pumps where insulation can't be upgraded. Our listed buildings guide covers what's involved.
Will I need to replace my radiators?
Sometimes a few, rarely all. Heat pumps run at lower flow temperatures than boilers, so some radiators may need upsizing to deliver the same warmth. Your heat loss survey tells us exactly which ones — the cost is itemised in your fixed quote, and radiator changes are covered within the granted installation.
