BUS
Boiler Upgrade Scheme
£7,500 standard · £9,000 oil/LPG households (summer 2026)
The Boiler Upgrade Scheme (BUS) is the UK's primary residential heat pump grant. Administered by Ofgem, it pays a fixed grant directly to the installer who deducts it from your quote. From summer 2026 the grant rises to £9,000 for households currently heated by oil, LPG or coal — a £1,500 uplift that's particularly relevant for rural Northumberland and County Durham properties.
Eligibility
Who qualifies for BUS
- Property in England or Wales (Scotland uses Home Energy Scotland Grant)
- Valid EPC with no outstanding insulation recommendations (or exemption)
- Currently heated by mains gas, oil, LPG, coal or direct electric resistance
- Replacement of the existing heating system in full (no parallel hybrids)
- MCS-certified installer (AMP is MCS certified)
- Property owner gives consent
Not eligible
Who's excluded
- New-build properties (built within last 12 months — different scheme applies)
- Social housing with grant funding already in place via RHI legacy
- Off-grid properties already running RHI-eligible biomass
- Properties without a valid EPC
The process
How BUS works, end to end
We handle the entire application — you never speak to the granting body. The grant is paid to AMP and deducted directly from your invoice.
1. Free survey + heat-loss calculation
Our engineer assesses the property and produces a designed system to MCS standards.
2. Fixed-price quote with grant deducted
The figure you see is the net cost after BUS — £7,500 for gas/electric households, £9,000 for oil/LPG.
3. BUS voucher application
We submit the application to Ofgem (typically issued within 2-4 weeks).
4. Install scheduled
Typically 4-10 weeks from accepted quote.
5. MCS-certified install completed
We issue paperwork and Building Control notification.
6. Final paperwork to Ofgem
They release the grant payment to us within 30 days.
7. Your invoice nets off the grant
You only ever paid the net figure.
Context
What you need to know
BUS is currently funded through to early 2028 with the £7,500 / £9,000 tiers. Government policy on heat pump support has been broadly stable over the last 18 months, but applying sooner rather than later removes timing risk — the budget is allocated annually and could be paused at short notice.
A particular note on the enhanced £9,000 tier: it applies to households currently heated by oil, LPG or coal, which covers a large share of rural Northumberland and County Durham properties. These households see the biggest running-cost saving from a heat pump (oil and LPG are price-volatile and expensive), making the post-grant payback period 4-6 years rather than 10+ on a gas-grid swap.
