UK Government Renewable Heating Grant
Government Funding for Air Source & Ground Source Heat Pumps in Orpington
The Boiler Upgrade Scheme is a UK government programme designed to accelerate the move from fossil fuel heating to low-carbon alternatives. It provides up to £7,500 toward the cost of an air source or ground source heat pump, deducted directly from your installation invoice, not paid as a rebate after the fact.
The scheme is open to homeowners in England replacing an existing fossil fuel heating system. There is no income threshold, it is not means-tested. Any eligible property qualifies, provided the installation is carried out by a BUS approved, MCS certified installer.
At Supreme Heating & Airconditioning, we are a registered BUS approved installer based in Petts Wood, Orpington. We manage the full eligibility check, EPC review, documentation and OFGEM application as part of our standard service. No additional charge. The grant simply comes off your bill.
Current Grant Amounts
How Much Can You Claim Under the Boiler Upgrade Scheme?
£7,500
Air Source Heat Pump
Suitable for most residential properties in Bromley. Mounted externally, no ground works required. The most common BUS installation type.
£7,500
Ground Source Heat Pump
For properties with available land or borehole access. Higher installation cost, but the same grant applies.
- The grant was increased from £6,000 to £7,500 in October 2023. Both air source and ground source installations now receive the same maximum grant amount. Biomass boilers were removed from the scheme in 2023.
Why Many Homeowners in Orpington Are Using the Scheme Now
- Energy policy continues shifting toward low-carbon heating. Acting during a live grant window reduces your transition cost significantly — and the direction of travel is not reversing.
- The BUS scheme runs on allocated government funding. Terms have already changed once. Properties that qualify today may face different criteria or reduced availability in future iterations.
- Minimum energy efficiency standards for rented properties are tightening. For homeowners planning to sell or remortgage, improving your EPC rating through heat pump installation is becoming a practical financial consideration.
- An air source heat pump costing £11,000 becomes £3,500 net after grant. For many Orpington properties, that net figure competes directly with a boiler replacement — but with 20+ years of low-carbon, grant-funded performance.
Qualifying Criteria
Who Is Eligible for the Boiler Upgrade Scheme?
Eligibility is determined by property location, EPC status, existing heating system and installer certification. We check all four during your free survey, before any commitment is made.
Property Located in England
The BUS scheme covers England only. Properties in Orpington and across the BR postcode area qualify. Wales and Scotland have separate renewable heating support scheme
Replacing a Fossil Fuel Heating System
An existing gas, oil or LPG boiler must be replaced by the heat pump. The existing system must be the property's primary source of space heating.
Valid Energy Performance Certificate
A valid EPC issued within the last 10 years is required. It must have no outstanding loft or cavity wall insulation recommendations, unless those improvements are technically impractical. An outdated EPC or one with addressable insulation gaps requires action before the grant can proceed.
Installation by a BUS Approved, MCS Certified Installer
The most common cause of failed or delayed applications. Supreme Heating & Airconditioning is a registered BUS approved installer, verifiable on the government's installer register at mcscertified.com.
Property Meets Insulation Standards
If your EPC flags addressable insulation improvements, those may need completing before the BUS application can proceed. We advise on this during the survey and can recommend insulation contractors if needed.

What Goes Wrong
Common Reasons Boiler Upgrade Scheme Applications Are Delayed or Rejected
Working with an experienced BUS approved installer eliminates the vast majority of application problems. Here are the most common issues, and how we prevent them.
Outdated or Invalid EPC
An EPC older than 10 years, or one that has never been issued, will fail the application. Outstanding addressable insulation recommendations also block the grant unless technically impractical.
- We check your EPC status at survey stage and advise on any action needed before we apply.
Installer Not on BUS Approved List
The most avoidable error. If your installer is not a registered BUS approved installer, the application cannot be submitted. Always verify installer registration before signing a contract.
- Supreme Heating is a registered BUS approved installer, verifiable at mcscertified.com.
Incorrect or Incomplete Documentation
BUS applications require specific documentation submitted in the correct format to OFGEM. Missing data, incorrect specifications or incomplete records delay or block approval.
- We manage all documentation and submission as standard, no additional action required from you.
Insulation Requirements Not Met
If your property has addressable insulation deficiencies on the EPC and you have not completed improvements, the application may be rejected. New builds are generally ineligible.
- We identify insulation requirements at survey stage and advise on solutions before the installation commitment is made.
Application Submitted at the Wrong Time
The BUS application must be submitted within a specific window relative to installation. Submitting too early or too late can invalidate the claim even if everything else is correct.
- We manage submission timing as part of the installation programme, you do not need to track this.
System Not Replacing Fossil Fuel Heating
The scheme requires an existing fossil fuel system (gas, oil, LPG) to be replaced. Properties on electric storage heating, district heating or with no fixed heating may not qualify.
- We confirm the existing heating system type at survey stage and advise on eligibility before any design work begins.

Qualifying Systems
Which Heat Pump System Is Right for Your Property?
Both qualifying systems attract the same £7,500 grant. The right system depends on your property, not the grant. We recommend based on what the survey tells us.
Air Source Heat Pumps in Bromley
Air source heat pumps are the most widely installed system under the Boiler Upgrade Scheme. Suitable for most residential properties in Orpington, no ground works, installed in two to four days. The full £7,500 BUS grant applies.
Ground Source Heat Pumps in Orpington
Ground source systems deliver consistent, high-efficiency performance year-round from stable underground temperatures. Higher installation cost than air source, but the same £7,500 BUS grant applies. Best for larger properties, rural plots and new builds.
Not sure which system is right for your property? That is exactly what the free survey answers. We assess your property and give you a clear, technically grounded recommendation.

BUS Questions Answered
Frequently Asked Questions About the Boiler Upgrade Scheme
The questions homeowners in Orpington ask us most about the Boiler Upgrade Scheme, answered clearly and directly.
How much does an air source heat pump cost in Orpington?
Air source heat pump installation in Orpington typically costs between £7,000 and £13,000 before the Boiler Upgrade Scheme grant. Eligible homeowners can access up to £7,500 from the government, applied directly as a discount on your installation invoice. Final costs depend on property size, insulation, radiator upgrade requirements and the system specified. We provide a full written quotation after a free survey, with no obligation.
Do air source heat pumps work in cold weather?
Yes, when correctly designed and installed. Modern systems operate effectively down to −20°C and below. The common complaint about heat pumps struggling in cold weather almost always traces back to an undersized system or one designed to run at too high a flow temperature. Our heat loss calculations and design process exist specifically to prevent this.
Will I need to replace my radiators?
Not necessarily all of them. As part of our survey, we measure every radiator’s output at heat pump flow temperatures. Some properties require no changes. Others need a handful of radiators upsized. We specify exactly which ones and at what size, with the cost included in your written quotation before any work begins.
How long does air source heat pump installation take?
A standard installation typically takes two to four days, depending on whether radiator upgrades are required, the complexity of the existing system and any electrical work needed. The full timeline is confirmed in your written quotation before any work starts.
Is my home in Bromley suitable for an air source heat pump?
Many properties in Bromley and across the BR postcode area are suitable, including older homes that have had insulation improvements. Suitability depends on insulation levels, radiator sizing, available outdoor space and electrical supply. We carry out a full heat loss assessment before recommending any system. If your property is not suitable, we will tell you clearly and explain exactly why.
How does the Boiler Upgrade Scheme grant work?
The Boiler Upgrade Scheme provides up to £7,500 toward a qualifying air source heat pump installation. It is not a rebate, it is applied as a direct discount on your installation cost by the installer. We check your eligibility, prepare all required documentation and submit the application to OFGEM on your behalf. There is no additional charge for this service.
Are air source heat pumps noisy?
Modern systems operate at approximately 40–50 decibels, similar to a quiet conversation or a refrigerator. UK permitted development guidelines include noise limits for outdoor units. We plan the positioning of every outdoor unit as part of our installation design to comply with those limits and minimise any impact on your home and your neighbours.
How long does air source heat pump installation take?
We install air source heat pump systems from recognised manufacturers including Daikin and Mitsubishi Electric. All installations are registered with the manufacturer directly on the day of completion, ensuring your warranty is in your name and valid from the start. Full MCS certification and compliance documentation is provided at handover.
