For the 2030 EPC C rating deadline

Spend what you have to,
not what you're told to

Your certificate lists improvements in an order that chases the best possible rating. You only need a C rating. We work out the cheapest way to get there - and whether it's worth doing at all.

Three questions, answered properly

What's my rating, in English?

Every EPC on the register, minus the jargon. What each feature means, what it's costing you, and whether you're already compliant.

What's the cheapest route to a C rating?

We test every combination of the measures on your certificate and find the one that clears a C rating for the least money - plus whether you'd likely qualify for an exemption instead.

Is it even worth keeping?

Put the cost of the work against what you'd walk away with if you sold. We don't mind which you pick - we just show you the numbers.

The order on your certificate isn't the order you should pay in

EPCs list improvements as a route to your property's potential rating - usually a B, sometimes an A. But the law only asks for a C rating. Follow the list from the top and you can easily buy points you never needed.

So we check every combination instead.

What's actually changing

Right now you can let a property rated A to E. Under the government's proposed rules, rented homes need to reach a C rating by 1 October 2030.

  • You'd have to spend up to £10,000 per property. Below that, you do the work.
  • If reaching a C rating costs more than the cap, you can register an exemption instead.
  • Fines go up to £30,000 per property.

These rules are still proposals and could change before 2030. We'll update this as they firm up.

Nobody pays us to tell you to spend money

Most EPC advice is free because an installer is picking up the bill - which is fine until the advice is “you need the expensive thing”. We take no referral fees and sell no insulation. If the cheapest answer is to do nothing and register an exemption, that's what we'll tell you.
