Short answer: A heat pump costs more upfront but delivers lower running costs, zero carbon emissions, and qualifies for a £7,500 government grant. For most East Anglia homes built after 1970, or any home rated EPC D or above, a heat pump is the better long-term choice — especially combined with solar panels.
Side-by-Side Comparison
The table below cuts through the noise and compares the key factors that matter for East Anglia homeowners:
| Factor | Heat Pump | Gas Boiler |
|---|---|---|
| Typical installation cost | £10,000–£15,000 (£2,500–£7,500 after BUS grant) | £1,500–£3,500 |
| Running cost (well-insulated home) | £700–£1,100/year | £900–£1,400/year |
| Carbon emissions | 50–75% lower than gas | High (fossil fuel) |
| Lifespan | 20–25 years | 12–15 years |
| Planning permission | Usually not required | Not required |
| Works with solar panels | Excellent synergy | No direct integration |
| EPC improvement | Significant (B/A band) | Minimal |
| Government grants | £7,500 BUS grant | None available |
| Hot water | Yes (via cylinder) | Yes (combi or system) |
| Future-proof? | Yes (aligns with net zero) | No (gas phase-out by 2035) |
Running Costs: The Real Numbers
Running cost comparisons depend on your home's insulation, the heat pump's SCOP efficiency, and your energy tariff. Here are realistic figures for East Anglia homes in 2026:
| Home type | Heat pump (SCOP 3.5) | Gas boiler | Annual saving |
|---|---|---|---|
| 3-bed semi (EPC C) | £780/year | £1,050/year | ~£270 |
| 4-bed detached (EPC B) | £950/year | £1,350/year | ~£400 |
| Heat pump + 4kW solar | £420/year | £1,050/year | ~£630 |
Based on 24p/kWh electricity, 7p/kWh gas, and 10,000 kWh annual heating demand. Combining heat pump with solar delivers the largest cost savings.
The £7,500 Boiler Upgrade Scheme Grant
The BUS grant makes heat pumps dramatically more affordable. Here is how it works in practice:
Important: The BUS grant is funded until March 2028, but annual budgets can be exhausted early. Installing sooner reduces the risk of missing out. We currently have availability in Cambridgeshire, Norfolk and Suffolk.
Is My Home Suitable? A Quick Checklist
Most homes in East Anglia are suitable. Check these points to get a rough idea before booking a survey:
Not sure? Our free home survey takes 45 minutes and confirms exactly what is needed — including whether you need radiator upgrades and what the total installed cost will be.
When a Gas Boiler Still Makes Sense
We believe in honest advice. A heat pump is not always the right choice right now:
Your current boiler has less than 3 years of life remaining and you cannot afford both insulation upgrades and a heat pump now — in this case, a new high-efficiency combi boiler with an upgrade plan in 2–3 years makes financial sense.
Your home is a listed building or in a conservation area with specific planning restrictions that make heat pump installation complex.
You rent privately and cannot make structural changes — speak to your landlord about the EPC C by 2030 landlord mandate, which will likely require them to act.
