What are the alternatives to heat pumps? A Consultation:

As the UK hurtles towards net zero and we cut our reliance on fossil fuels, heat pumps are set to become the de facto heating system for the vast majority of building projects. But what happens when heat pumps aren't suitable? Luckily, there’s a consultation for that!

When a heat pump isn't considered a viable solution for a building, what alternatives are there that align with the UK's net zero objectives?

DESNZ is exploring the role of alternative, clean heating solutions for buildings where common heat pump designs aren’t the best fit.

📅 You’ve got until 10th February 2026 to respond:

📈 Let’s start with some stats… buildings in the UK (or, more correctly, the people inside them) generate more than a fifth of all CO2 emissions, with 26.5 million homes currently reliant on fossil fuel heating.

The Future Homes Standard will soon draw a close to gas boiler installs in new builds. This is already happening in Scotland.

Meanwhile, the Warm House Plan and Boiler Upgrade Scheme encourage us to switch to low carbon heating when completing renovation projects on existing buildings.

But heat pumps aren't the best solution for every scenario. For large industrial buildings, warehouses, manor houses, small mid-terrace homes and high-rise flats, there are more sensible options out there.

This consultation wants your thoughts on when these systems are more viable, how they can help reduce emissions, and how they can reduce fuel bills for occupants:

🟢 Direct electric heaters

🟢 Electric boilers

🟢 Infrared panels

🟢 High temperature heat pumps

🟢 Air to air heat pumps / Air conditioning 

🟢 Exhaust air heat pumps

🟢 Thermal energy storage / Heat batteries

🟢 Storage heaters

🟢 Hybrid heat pumps

🟢 Biomass and waste fuel boilers

🟢 Low carbon heat networks

I won't regurgitate the pros and cons of each system here. If you have an opinion, click the link and have a read.

This consultation doesn't consider any future role offered by hydrogen or biogas options. (These will be covered in a separate review).

I know there are plenty of folk out there inventing and promoting alternatives heating systems, and struggling to be heard above the more well-established tech. Hopefully some good will come out of this one 😊
