Comments landlords left on Property118 after the 2030 rules were announced, in their own words. They aren't connected to Plan C. Only 16% of landlords are very confident in current EPC ratings (Leaders Romans Group, reported Sep 2025).
“the utter lack of transparency over what building works generate what points”
“how does anyone know what is going to count or not?”
“I also asked my MP who said no one knows.”
Your certificate already says what each job is worth: the rating after every step. We read it, and show you the score each job buys.
“Getting it up to C is £10k plus, on a rent of £650 per month.”
“You could spend it and still get a D so pointless.”
“spending £15k in order to save the tenant £250 per year”
We find the cheapest set of jobs that gets you over the line, not the full list. If C would cost more than the £10,000 cap, we show where you can stop and register an exemption.
“same flat different assessors equals different EPC band”
“I switched assessor and without any work got Band C”
We tell you when a new assessment is worth booking, and when it isn't: a replacement EPC that scores lower cancels the C you already have.
“Or will we have cowboy companies profiteering from the rush to comply?”
“clearing failed cavity fill has cost £15,000-20,000”
We don't sell installs, take referral fees or pass your details on. You get the plan before anyone quotes.
“Some appear to have closed, others redirect you to different agencies”
“Accessing ECO4 is best done by the tenants direct”
We match each job to the schemes open today, say who has to apply (often your tenant), and only take money off the price when you've told us the conditions are met.
We find every certificate on the official register for that street.
We read its rating and the jobs the assessor listed, with costs and the score after each.
The cheapest jobs to reach C, in order, with grants, the cap and when to get reassessed.
Picked from your certificate's own list to reach C for the least money, with the typical cost and the score after each job.
Everything else on the certificate, crossed out, so you know what to say no to.
Which schemes might pay, what they need from you, and whether the money counts towards the cap.
If C would cost too much, the plan shows which jobs use up the cap the way the rules require, and where you can register an exemption.
Under the rules as announced, a C on today's rating lodged in time counts until the certificate expires. The plan says whether that's worth doing.

typical saving on those 20. Yours will differ.
Savings use the midpoint of typical costs. Most of the cheaper routes rely on our estimated scores, which every plan marks as estimates. These are test results, not homes where the work was done.
Under the rules the government has announced, a home that shows C on today's rating, on an EPC lodged by 30 September 2029, counts as compliant until that certificate expires. That can be 2039. Miss it and the home is judged on new fabric-first measures, which will usually cost more to meet.

No. We don't install anything, take referral fees or share your details. That's the point.
It's guidance worked out from your home's published certificate. We aren't assessors, surveyors, lawyers or financial advisers, and we never see the home. Use the plan to decide what to ask for, then get quotes and a new EPC before you rely on a score. What the plan can and can't tell you.
Costs are the typical ranges printed on your certificate, not quotes. Where we follow the certificate's own order, the scores are the assessor's. Where the cheapest route skips steps, the score is our estimate and we say so, with a margin. A new assessment can still land a few points either way.
Not yet. The government confirmed it on 21 January 2026 and still needs Parliament to pass it, aimed at 2027. We keep every rule in one place and update plans when it changes.
You spend up to the cap, including grants (except the Boiler Upgrade Scheme), then register a 10-year exemption. The plan shows which jobs that means and where you can stop.
England and Wales, yes. Scotland has its own rules and isn't covered.
