Are Heat Pumps Worth It in East Anglia? Costs, Savings & Real Experience

Air source heat pumps are the most significant shift in home heating technology in a generation. With the UK government offering £7,500 through the Boiler Upgrade Scheme and 0% VAT on installations, the financial case has never been stronger. But are they actually worth it for homes in East Anglia?

We have installed over 200 heat pump systems across Cambridgeshire, Norfolk, and Suffolk. Here is what we have learned about real-world performance, costs, and customer satisfaction in our region.

What Does a Heat Pump Actually Cost?

The total installed cost of an air source heat pump system ranges from £8,000 for a small flat to £22,000 for a large detached property. After the £7,500 BUS grant (which we apply for on your behalf), your net cost is typically £500 to £14,500. The average home in East Anglia pays £4,500-£7,500 after the grant.

This price includes the outdoor unit, indoor components, hot water cylinder replacement (if needed), any radiator upgrades, electrical work, MCS certification, and a 5-year workmanship warranty.

Heat Pump vs Gas Boiler: Running Costs Compared

At current energy prices (electricity 24.5p/kWh, gas 6.76p/kWh), a heat pump running at a Coefficient of Performance (COP) of 3.5 costs effectively 7p per kWh of heat delivered. A gas boiler running at 90% efficiency costs 7.5p per kWh of heat. The running costs are roughly comparable, with the heat pump marginally cheaper.

The real savings come from combining a heat pump with solar panels. If you generate your own electricity, the heat pump running cost drops dramatically. A typical 4kW solar system can provide 40-60% of a heat pump electricity needs across the year, pushing annual heating costs well below what any gas boiler can achieve.

Do Heat Pumps Work in Cold East Anglia Winters?

East Anglia winters are cold but rarely extreme. Temperatures typically range from 0 to 8 degrees Celsius in winter, with occasional dips to minus 5. Modern heat pumps operate efficiently down to minus 20 degrees — far below anything East Anglia experiences.

In our installations across the region, we consistently see COP values of 3.0-3.5 in winter and 4.0-4.5 in summer. Our customers in Ely, Cambridge, and Bury St Edmunds report their homes are warmer and more comfortable than they were with gas or oil boilers.

Which Homes Suit Heat Pumps Best?

Not every home is equally suited to a heat pump without preparation. The best candidates are:

• Well-insulated homes with cavity wall or external wall insulation and adequate loft insulation
• Properties with space for a hot water cylinder (typically an airing cupboard)
• Homes with outdoor space for the external unit (roughly 1m x 1m, away from neighbours)
• Properties replacing oil or LPG boilers (the savings compared to these fuels are substantial)
• New-build or recently renovated properties with modern insulation levels

The BUS Grant: How It Works

The Boiler Upgrade Scheme provides a £7,500 grant towards air source heat pump installation. We handle the entire application process. You need a valid EPC (Energy Performance Certificate) for your property, and your current heating system must be a fossil fuel boiler (gas, oil, or LPG). The grant is deducted directly from your invoice — you never handle the money.

The scheme has been extended to at least March 2028. There is no income test or means assessment. It is available to all eligible homeowners across England and Wales.
