Is the Heat Pump Grant Worth It? Honest Assessment
For the vast majority of UK homeowners: yes, the heat pump grant is absolutely worth it. The £7,500 BUS grant brings the net cost of a heat pump down to the same ballpark as a new gas boiler — but with lower running costs over 20-25 years. We have done the maths honestly, including the scenarios where it might not make sense.

The Numbers
The grant covers 50-93% of the total cost depending on installation complexity. See our cost guide for detailed breakdowns.
When It Is Clearly Worth It
- Oil or LPG heating: Switching saves the most — running costs can drop 30-50%
- Well-insulated homes: Heat pumps perform best, lowest running costs
- Planning to stay 5+ years: Running cost savings accumulate over time
- Combined with solar panels: Free solar electricity powers the heat pump
- Replacing an old boiler anyway: The incremental cost vs a new gas boiler is small after the grant
When It Might Not Be Worth It
- Very poorly insulated home with no plans to insulate
- Planning to move within 2-3 years (though it adds property value)
- Very new, efficient gas boiler that does not need replacing
Even in these cases, the grant makes the economics more attractive. Check whether a heat pump is worth it for your specific situation.
Lifetime Cost Comparison
| Metric | Gas Boiler | Heat Pump (after grant) |
|---|---|---|
| Upfront cost | £3,000-£4,000 | £2,500-£7,500 |
| Annual running cost | £1,200 | £1,000 |
| Lifespan | 12-15 years | 20-25 years |
| Lifetime cost (20 years) | £27,000-£28,000 | £22,500-£27,500 |
Indicative figures. Actual costs depend on property, insulation, tariff, and usage.

Frequently Asked Questions
Is the heat pump grant worth it?
For most homeowners, yes. Net cost is comparable to a gas boiler, with lower running costs over 20-25 years.
When is it not worth it?
Rare cases: very poor insulation, moving soon, or a brand new gas boiler.
How long to break even?
Typically 5-8 years through lower running costs, then 12-17 years of savings.
About Heat Pump Grant Value
The Boiler Upgrade Scheme grant fundamentally changes the economics of heat pumps for UK homeowners. At £7,500, it bridges the gap between heat pump installation costs and gas boiler prices. Combined with lower running costs, the lifetime cost comparison favours heat pumps in most scenarios. Adding solar panels tips the balance further.
