£29, one-off
The cheapest way to reach a C rating, worked out properly
Your certificate lists improvements in an order aimed at the best rating your property could get. The law asks for a C rating. We work out which combination clears that line for the least money, and whether you'd be better off registering an exemption instead.
Start with the free version
Put in a postcode and you'll see the headline finding for any property without paying anything. The report goes deeper, it doesn't unlock a different answer.
What you get for £29
Every route costed, cheapest first
We test all the combinations that clear a C rating and rank them, so you can weigh a slightly pricier option that also cuts the bills.
Your exemption case, written up
If the cheapest route costs more than the cap, we set out the argument and the evidence you'd need for the PRS Exemptions Register.
A spec you can send to installers
The measures in plain terms, ready to paste into an email, so you're quoting three firms on exactly the same scope.
The assumptions worth challenging
Anything marked 'assumed' on your certificate is where ratings most often go wrong. We flag the ones that would change your bill.
Who it's not for
If your property is already a C rating or better, we'll tell you that free and you should keep your £29. Same if your certificate has no improvement measures recorded, because there'd be nothing for us to work with and a fresh assessment is the better spend.
Payments aren't on yet
This is an early build. The free analysis works today and is worth running now, since it answers most of the question on its own.
