Boiler Tax, Boiler Levy & the Clean Heat Market Mechanism: What It Means for You

If you’ve been hearing about the boiler tax, the boiler levy, or the government’s Clean Heat Market Mechanism (CHMM), you’re not alone. These new policies are set to affect boiler prices across the UK – and homeowners in Kent should take note.

From April 2025, the CHMM is expected to go live. While details are still being finalised, the changes are already pushing up boiler prices.

What Is the Boiler Tax / Clean Heat Market Mechanism?

The Clean Heat Market Mechanism (CHMM) is a government initiative designed to promote low-carbon heating.
Boiler manufacturers must sell a minimum number of heat pumps in relation to their gas boiler sales.
If they fail to hit the target, they’ll be fined £500 per missing heat pump.
This scheme is due to start from April 2025, but some elements remain unconfirmed.

Why Is the Boiler Levy Increasing Prices?

To cover potential fines or losses from promoting heat pumps, many boiler manufacturers raised prices in early 2024.
Increases ranged between £95–£120 per boiler.
Another boiler price rise is expected before the policy takes effect in 2025.
There’s still a lot of uncertainty, but the trend is clear – boiler prices are going up.

Boiler Replacement Advice for Homeowners in Kent

If you’re planning a boiler replacement, it could be cheaper to act now before further price hikes.
Some experts estimate a £100–£300 increase per boiler as the Clean Heat Market Mechanism deadline approaches.

Why Is This Happening?

The UK government is aiming to reduce carbon emissions from home heating.
The CHMM (or boiler tax) pushes manufacturers to promote heat pumps instead of traditional gas boilers.

Are Gas Boilers Being Banned?

No, gas boilers are not being banned.
We expect them to remain available for decades.
That said, we can’t confirm how future policies will affect pricing – costs could continue to rise.
