Why the passport exists

Most heat pump quotes are inflated because installers have to guess.

The Warmur Passport removes that guesswork entirely by doing the complex design work upfront before you ever speak to installers.

It gives you certainty, protects you from mis-selling and ensures your installation is low-disruption, affordable and built to last.

How the Warmur Passport makes heat pumps affordable

When installers know exactly what they’re walking into, they stop pricing in fear.

The Passport removes that fear. It includes:

  • full 3D digital scan
  • room-by-room heat-loss model
  • correct heat pump size
  • radiator plan
  • flow-temperature modelling
  • comfort analysis
  • future tariff/solar/battery pathways

This level of clarity eliminates thousands in unnecessary costs.

Turning complexity into clear decisions

Heat pumps are complex systems. Getting them right means balancing heat loss, radiator performance, flow temperature, system size, and future energy option , all at once.

The Warmur Passport brings this together into one clear design, so:

  • installers don’t have to assume or over-specify
  • homeowners don’t have to interpret technical reports
  • decisions are based on evidence, not pressure

In short, we handle the complexity, so you don’t have to.

Change only what needs changing

The Warmur Passport replaces assumptions with evidence so you avoid:

  • inflated quotes driven by uncertainty
  • oversized systems and “just in case” design
  • unnecessary radiator, cylinder or insulation upgrades
  • ripping up floors or deep retrofit
  • poor comfort and costly regret later

Your Passport shows exactly what your home needs and what it doesn’t.

Installers stand behind your passport

Because the Passport is based on real engineering, not assumptions, installers can see exactly what your home needs before they quote.

That’s why Warmur Installers use your Passport as the foundation for quoting, with fewer unknowns and fewer surprises.

Installers in the Warmur Network are selected for their technical competence and work from the same design-grade model you see, so systems are designed properly before anything is sold or fitted.

Your comfort. Your cost. Your clarity.

That’s our commitment.

About the Passport fee

There is a cost to prepare a Passport because it includes real modelling and technical work. But if you install through the Warmur Network, the fee is automatically refunded. Warmur only prospers when your installation succeeds.
