Best Conservatory Heating UK 2026
A conservatory is a glorious summer room and a useless winter one — unless you heat it efficiently. The wrong heater costs £200+/month to run. The right setup makes the room usable year-round for around £30-50/month. Five heating options compared by running cost, install hassle and value.
Why it matters
Conservatories lose heat fast through the glazing. A normal electric heater pumps energy out the windows. Infrared panels and air-source mini-splits target the people and surfaces in the room directly, cutting running costs by 30-50% vs convection heaters.
How we chose
- Real-world running cost on a UK winter day (not manufacturer claims)
- Install difficulty — DIY vs electrician vs FENSA-required
- Compatibility with conservatory regs (no heat into the building from extension)
- Quiet operation (you're sitting in there reading, not running a leaf-blower)
