If you have been half following the EPC story for the last few years, you would be forgiven for thinking nobody knows what is happening.
A standard was proposed, then delayed, then dropped, then revived. Dates came and went. 2025, 2028, 2030, all of them quoted confidently by somebody.
That part is over. In January 2026, the government published its response to the consultation on the energy performance of privately rented homes, and landlords finally have a date to work to.
What has actually been confirmed?
Privately rented homes will need to meet the equivalent of EPC C, measured against new metrics, and there is a single deadline.
1 October 2030. All tenancies.
That last point matters more than it looks. Earlier proposals had a two-stage approach, with new tenancies having to comply from 2028 and existing ones catching up by 2030. That has gone. The government’s response says explicitly that there will not be an earlier compliance date for new tenancies.
So if you have read that you need to be ready by 2028 when you next re-let, that is out of date. One date for everybody: October 2030.
How is the standard measured?
This is the genuinely new bit, and it is not simply the EPC rating you are used to.
The standard is a dual metric. A fabric performance standard comes first, so the focus is on the building itself, insulation, draughts, the things that stop heat escaping. Then you choose one of two further standards to meet, either a heating system standard or a smart readiness standard.
The practical read is that you cannot fix this purely by swapping a boiler or fitting a smart thermostat. The fabric comes first, then you have a choice about the second half.
What will it cost?
There is a cost cap, and it has gone up considerably from the figure many landlords have in their heads.
The cap is £10,000 per property. The old proposed cap of £3,500 is no longer the number.
For properties worth under £100,000, the cap is the lower of £10,000 or 10% of the property value.
The government’s own impact assessment estimates the average spend needed will be £5,400 per property, not the full cap.
If your property still does not meet the standard after you have spent up to the cap, you can register an exemption. The cost cap exemption lasts 10 years, as do the negative impacts and property value exemptions. Most other exemptions run for 5 years.
So the worst case is capped, and the likely case is a little over half the cap. That is not nothing, but it is a planning problem rather than a crisis, and you have four years.
Is there anything in it for a landlord already at C?
Yes, and it is worth knowing about. If your property achieves an EPC C or above on the current energy efficiency rating before 1 October 2029, that is recognised as compliant under the future standard until that certificate expires.
In other words, an existing C rating does not become worthless overnight. It buys you time, which is a reason to get a current EPC done rather than letting an old one lapse.
Why are so many sources still wrong about this?
Because the story changed repeatedly, and a lot of articles were written at the wrong moment and never updated. If you go looking, you will still find plenty of guidance quoting the dead 2028 date for new tenancies, or the old £3,500 cap.
It is worth checking the date on anything you read about this. Nothing in this piece is our opinion of what might happen. It is what the government response of January 2026 actually says, and we have named the source at the foot so you can check it yourself.
What should you do between now and 2030?
Get a current EPC for each property, and note the expiry date. You cannot plan without knowing where you are starting from.
Look at fabric first. Loft insulation, cavity walls where suitable, draught proofing, glazing. That is the order the standard is built around, so it is the order to spend in.
Plan the work around your voids and your maintenance cycle rather than in a panic in 2029. Insulation fitted while a property is empty is cheaper and easier than insulation fitted around a tenant.
Look at what grant funding is available before you commit. Schemes change, so check what is open when you are ready to spend.
Keep every invoice and certificate. If you ever need to claim the cost cap exemption, the evidence of what you spent is the whole case.
Not sure where your portfolio stands?
If you would like a straightforward view of which of your properties are likely to need work and which are probably fine, talk to us. Four years sounds like plenty until it is eighteen months.
Frequently asked questions
What EPC rating will rented homes need and by when?
The equivalent of EPC C, measured against new metrics, by 1 October 2030. This was confirmed in the government’s response to the consultation on improving the energy performance of privately rented homes, published on 21 January 2026.
Is there an earlier 2028 deadline for new tenancies?
No. That was proposed but dropped. The government response states explicitly that there will not be an earlier compliance date for new tenancies. There is one deadline for all tenancies.
How much will landlords have to spend?
The cost cap is £10,000 per property, or the lower of £10,000 and 10% of the value for properties worth under £100,000. The government’s impact assessment estimates an average spend of £5,400 per property.
What if my property cannot reach the standard?
If it still falls short after you have invested up to the cost cap, you can register an exemption. The cost cap, negative impacts and property value exemptions last 10 years. Most others last 5 years.
Does my current EPC C still count?
If the property achieves EPC C or above on the current energy efficiency rating before 1 October 2029, that is recognised as compliant under the future standard until the certificate expires.
If you know a landlord who would find this useful, please pass it on.
