Government grant — England & Wales
Get up to £9,000 off your heat pump installation
The Boiler Upgrade Scheme (BUS) provides a government grant towards replacing a fossil fuel boiler with a heat pump. The grant is deducted directly from your installation cost — you never pay it upfront or claim it back yourself.
We handle the entire BUS grant application via our MCS certification partner Heat Pump Go. For eligible installations you get the full grant deducted from your bill with zero paperwork on your end.
£7,500
Standard BUS grant — most properties
Replacing a gas, oil or LPG boiler with an air source or ground source heat pump.
Oil & LPG homes: £9,000 grant available from 21 July 2026 to 31 March 2027
Eligibility note: The insulation prerequisite has been scrapped. You no longer need to complete loft or cavity wall insulation before applying for the BUS grant. Since 28 April 2026, a valid EPC is no longer a mandatory requirement for the scheme.

- Note: insulation requirement has been scrapped from April 2026
You may not be eligible if...
- You are a tenant, not the property owner
- The property already has a heat pump installed
- You have already claimed a BUS grant for this property
- The property is in Scotland (separate scheme applies)
- ℹNew builds — different rules apply, ask us
- ℹListed buildings may need additional assessments
The process
We handle it all — 5 simple steps
1
Free survey
We visit your property, carry out a heat loss calculation, confirm eligibility and confirm your grant amount (£7,500 or £9,000).
2
Grant applied via Heat Pump Go
If your property is eligible, Heat Pump Go — our MCS certification partner — submits your BUS voucher application. This must be done before installation starts.
3
Voucher approved by Ofgem
Ofgem typically issue the voucher within 2–6 weeks. We track it and keep you updated.
4
Installation completed
Your Mitsubishi Ecodan heat pump is installed, commissioned and handed over with full documentation.
5
Grant deducted — you pay the balance
We claim the grant directly from Ofgem. Your final invoice already has the grant amount deducted.

FAQs
BUS grant questions
Do I need an EPC to qualify for the Boiler Upgrade Scheme?
No. Since 28 April 2026, a valid Energy Performance Certificate (EPC) is no longer a mandatory requirement for the Boiler Upgrade Scheme. If your property already has a valid EPC, its certificate number must be provided. If you do not have a valid EPC, alternative evidence will be required to establish eligibility. Eco Care Solutions Ltd works with Heat Pump Go, which handles BUS applications and MCS documentation under our partnership agreement.
Do I need to do anything to get the grant?
Very little — we handle everything via Heat Pump Go. You will need proof of property ownership, and an EPC certificate number if your property has a valid EPC. Beyond that, we manage the application and deduct the grant from your final invoice for eligible installations.
Has the insulation requirement been removed?
Yes — the BUS rules no longer require an EPC without loft or cavity wall insulation recommendations. You no longer need to complete loft or cavity wall insulation before applying for the BUS grant. This removed one of the biggest barriers to the scheme.
How long does the grant application take?
The BUS voucher is typically issued by Ofgem within 2–6 weeks of application. It is valid for 3 months. We submit your application as soon as you confirm you would like to proceed.
Can landlords claim the BUS grant?
Yes — landlords can apply for the BUS grant for rental properties. The same eligibility criteria apply. Contact us to discuss eligibility for your rental portfolio.
Is the BUS grant available in Wales?
Yes — the BUS covers both England and Wales, administered by Ofgem. Additional Welsh Government schemes (ECO4, Warm Homes Programme Wales) may also be available for lower-income households.
What is the difference between £7,500 and £9,000?
The standard grant is £7,500 for all eligible properties including those on mains gas. The £9,000 grant is a temporary uplift for homes currently heated by oil or LPG (off the gas grid). It is available from 21 July 2026 to 31 March 2027 only.
