Air source heat pumps are becoming increasingly popular in Bromley, and across the South East – not only for their efficiency, but also for the generous government support available. If you’re considering switching from a traditional gas boiler to a low-carbon heating system, cost is usually the first question.
In this guide, we’ll break down the average costs of air source heat pump installations in Bromley, what factors affect pricing, and how the Boiler Upgrade Scheme (BUS) can save you thousands.
Typical Air Source Heat Pump Costs in Bromley
On average, the cost to install an air source heat pump in a Bromley home costs upwards of £10,000. This includes the heat pump unit itself, labour, and associated system upgrades (such as hot water cylinders and new radiators if required).
However, the final price can vary depending on:
- Property size & heat demand – Larger homes or those with higher heating needs require more powerful systems.
- System type – Monobloc systems tend to be cheaper than split systems, but the choice depends on property design and energy usage.
- Existing heating set-up – Homes with older pipework or radiators may need upgrades for optimal efficiency.
- Insulation levels – A well-insulated home in Bromley can reduce system size and installation cost.
At NCC South East, we provide free home surveys to give you an accurate quotation tailored to your property, so you’re never hit with unexpected extras.
Government Grants – Save £7,500 in Bromley
The Boiler Upgrade Scheme (BUS) provides a grant of £7,500 for eligible homes installing an air source heat pump. As an MCS-accredited installer, NCC South East manages the application process for you – from eligibility checks to submitting paperwork with Ofgem.
That means if your installation cost is £12,000, you could pay as little as £4,500 after the grant.
Servicing & Running Costs
Once installed, air source heat pumps are relatively low-maintenance. We recommend an annual service to keep your system at peak efficiency and to maintain manufacturer warranties. Regular servicing costs typically range between £150 and £250 per year, covering checks on refrigerant levels, filters, and system controls.
