Boiler Upgrade Scheme
Claim up to £7,500
Toward Your Heat Pump.
The Boiler Upgrade Scheme (BUS) is a government initiative offering eligible households in England and Wales a grant of £7,500 toward the cost of an air source heat pump. The grant is deducted directly from your installation invoice — there is no need to fund it yourself and reclaim later.
Eligibility is assessed on a per-property basis using the scheme's published criteria, including your current heating system, property type and EPC rating. Not every home qualifies, and we will always confirm eligibility during your free survey before any commitment is made.
As KJD Heating partners with an MCS-registered umbrella company, your installation meets the technical standards required by the scheme. We handle the entire BUS application on your behalf, so the process is straightforward and stress-free.
Why heat pumps?
The Benefits of
Air Source Heat Pumps.
A modern air source heat pump is one of the smartest investments you can make in your home — slashing running costs, lowering emissions and future-proofing your heating for decades to come.
Cut Energy Bills by up to 60%
Air source heat pumps are 3–4× more efficient than a gas boiler — producing 3–4 units of heat for every unit of electricity consumed.
Dramatically Lower Carbon Footprint
Heat pumps produce no direct carbon emissions at the point of use and run on an increasingly renewable electricity grid.
£7,500 Government Grant Available
The Boiler Upgrade Scheme (BUS) provides a £7,500 grant toward installation for eligible homeowners in England and Wales.
Fully MCS-Compliant Installation
We partner with an MCS-registered umbrella company so your install qualifies for the BUS grant and meets the highest industry standards.
Reliable Heating in Cold Weather
Modern ASHPs deliver efficient heating down to around -20°C — keeping your home warm even on the coldest Essex winter nights.
Long-Life, Low Maintenance
With fewer moving parts than a gas boiler, a well-maintained heat pump typically lasts 15–20 years with minimal servicing.

Government Grant
£7,500
The Boiler Upgrade Scheme (BUS) provides a £7,500 grant to eligible households — deducted directly from your invoice by KJD Heating.
Typical Contribution
£2,500 – £6,500
After the BUS grant your out-of-pocket cost is usually £2,500 – £6,500 — often less than a comparable boiler replacement.

Is my home suitable?
Most Homes Are
Suitable.
Heat pumps work best in well-insulated properties with larger radiators or underfloor heating. But modern systems can heat many types of home effectively. The only way to know for certain is a proper survey — which we provide free of charge.

Radiator Upgrades
Bigger Radiators.
Better Performance.
Heat pumps work best at lower flow temperatures — usually 35–45°C instead of the 65–70°C of a traditional boiler. To keep every room comfortably warm at these lower temperatures, your existing radiators often need to be upgraded to larger sizes with greater surface area.
As part of your free survey we carry out a full radiator assessment for every room. If upgrades are needed we include them in your fixed-price quote — no surprise add-ons, no upsells on installation day.
Bigger Surface Area
Larger radiators give off more heat at the lower flow temperatures a heat pump runs at — keeping rooms warm without forcing the system to work harder.
Lower Flow Temps
Heat pumps are most efficient at 35–45°C. Properly sized radiators let your system run at these lower temperatures and cut running costs.
Often Reuse Existing Pipework
In many homes we can swap radiators on the existing pipework with minimal disruption — no major floor or wall chases required.
Quoted As Part Of Your Install
If new radiators are needed, we include them in your fixed-price quote. No surprise extras on installation day — you know the cost upfront.

FAQ
Heat Pump
Questions Answered.
Everything homeowners in Colchester and Essex ask us about air source heat pumps, grants and installation.
A typical ASHP installation in a 3-bed Essex home costs £10,000 – £14,000 before the £7,500 Boiler Upgrade Scheme grant. Most households pay £2,500 – £6,500 out of pocket after the grant — comparable to a like-for-like boiler replacement.
Eligibility is assessed against published BUS criteria, including property type, current heating system and EPC rating. We carry out a free survey to confirm eligibility before any commitment and handle the full grant application on your behalf.
Most homes are suitable, including period properties — provided insulation is reasonable and radiator sizes are appropriate. Where existing radiators are undersized we can often upgrade them at the same time. A free survey is the only way to know for sure.
Modern ASHPs are very quiet — typically 35–45 dB at 1 metre, similar to a fridge hum. Units are wall-mounted clear of neighbours, and we always follow MCS installation guidance on placement and acoustic considerations.
Most domestic air source heat pump installations are completed in 1–2 days, with minimal disruption. Hot water cylinder upgrades or radiator changes can extend this — your fixed quote will outline the exact programme.
Heat pumps are low maintenance compared with gas boilers. We recommend an annual service to keep efficiency high, maintain any warranty and spot small issues early. We offer ongoing service plans for KJD-installed systems.
Not always, but larger radiators (or underfloor heating) help a heat pump run at its most efficient lower flow temperatures. Our survey includes a radiator assessment and we will quote any upgrades as part of the fixed price.
Yes — KJD Heating is BPEC Level 3 qualified in heat pump installation, Gas Safe registered and works with an MCS-registered umbrella company so your install qualifies for the BUS grant and the highest industry standards.
