Heat pumps cost less when they’re designed properly. Warmur makes that possible






Heat pumps don’t fail homeowners. Bad design does.
In the UK, most heat pumps are:
- oversized
- paired with unnecessary radiator upgrades
- quoted with thousands in “contingency"
This is why heat pumps get a bad reputation and why they seem expensive. Warmur was created to fix the design problem.

The Warmur Passport is what makes heat pumps affordable
When installers know exactly what your home needs, they stop pricing in fear and start pricing fairly.
The Warmur Passport gives everyone clarity upfront to:
- avoid unnecessary radiator upgrades
- remove “just in case” price increases
- design right before any quote is finalised
- minimise surprises on site
- alignment with the £7,500 Boiler Upgrade Scheme
This is how Warmur removes the guesswork that pushes prices up so that, for many homes, a heat pump can cost about the same as a gas boiler.
