Confirmed on 21 January 2026. Around three million privately rented homes need work by 1 October 2030, the penalty for getting it wrong rises six-fold — and there is a dated route to compliance that most coverage does not mention.
Your rental property must reach EPC C or equivalent by 1 October 2030, or you risk a penalty of up to £30,000. The cost is capped at £10,000 per property, and a property already at C before 1 October 2029 is grandparented in.
This is the deadline with the longest lead time and the largest bill of the four now facing landlords. It is also the only one where doing something in the next three years can legally change what you owe in 2030 — which is the part worth reading carefully.
This guide is part of our landlord compliance series — sourced guides to the biggest deadlines and duties facing English landlords right now.
Today’s minimum is EPC band E, and it has applied to all relevant existing tenancies since 1 April 2020. You cannot let, or continue to let, a property rated below E unless you have a valid exemption registered.
Today’s cost cap is £3,500 including VAT, and today’s maximum penalty is £5,000 in total per property — up to £2,000 for letting a non-compliant property for less than three months, and up to £4,000 for three months or more, each with a possible publication penalty.
Every one of those three numbers changes in 2030. The jump is large, and it is the reason this is a planning problem rather than a paperwork one.
The standard. EPC C equivalent, for all tenancies, from 1 October 2030. There is a single compliance date — no earlier deadline for new tenancies and a later one for existing ones, which is how the previous proposals were structured and how a lot of older commentary still describes it.
The cost cap. £10,000 per property, measured over ten years, up from £3,500. Spend it and still not meet the standard, and you can register a cost-cap exemption valid for ten years and keep letting.
The penalty. Up to £30,000 per property per breach. Note this is not the £40,000 general housing-offence maximum that rose on 1 May 2026 under the Renters’ Rights Act — different regime, different figure, and the two are frequently conflated.
The enabling law is not made yet. Government said it will seek to lay a statutory instrument amending the PRS Regulations, aiming for it to come into force in 2027. So the policy is confirmed and the direction is settled, but the operative detail sits in an instrument that does not exist yet and could still shift.
The umbrella policy. This PRS-MEES reform was published as part of the government’s Warm Homes Plan — DESNZ’s flagship home-decarbonisation programme, published the same day, 21 January 2026, committing £15 billion over this Parliament to upgrade up to five million homes. The Warm Homes Plan sets the wider commitment; the government response above is the specific document confirming what it means for private landlords.
The standard is being set against new EPC metrics, not the single rating on your current certificate. The confirmed structure is a dual-metric standard: a fabric performance metric first, then your choice of either the smart readiness metric or the heating system metric as the second.
The mechanism behind this is a wholesale replacement of how EPCs are calculated. Today’s Energy Efficiency Rating is built on SAP (or RdSAP for existing homes); government is replacing it with a new calculation methodology called the Home Energy Model (HEM), with the resulting certificate product itself referred to as Home Energy Model: EPCs (HEM:EPC). This is still subject to consultation and no launch date has been fixed — an earlier target date has already slipped once. What you can rely on today is the confirmed dual-metric structure above, not a firm date for when HEM:EPC itself goes live.
The practical consequence is uncomfortable but worth being clear-eyed about: a property sitting at C on today’s certificate is not automatically compliant in 2030, because it will be assessed on different things — fabric first among them. Insulation, in other words, is likely to matter more than it does under today’s rating, and a good score achieved mainly through heating or lighting may not carry across.
The government response confirms a grandparenting provision: a property that scores C or higher against the current Energy Efficiency Rating before 1 October 2029 remains compliant until that EPC expires.
Since domestic EPCs run for ten years, a qualifying certificate registered in, say, 2028 carries its compliance well past 2030 — without you having to meet the new dual-metric standard in the meantime. This is not a loophole; it is an explicit transitional provision, and it is the single most actionable thing on this page.
Two honest caveats. First, it only helps if the property genuinely reaches C on the current rating — it is not a way of avoiding work on a property at E or F, only of locking in work already done or done sooner. Second, it defers rather than removes the obligation: when the certificate expires, the standard that applies is the one in force then. If your property is at D and within reach of C, though, the difference between doing that work before October 2029 and after it is material.
You will see both quoted, usually without attribution and often as though they contradict each other. They come from different documents at different stages, and the distinction matters.
£6,100 to £6,800 is from the options assessment published alongside the consultation: the average landlord cost under the government’s preferred option, varying with the fabric standard chosen. It also modelled around three million privately rented properties needing upgrade by 2030 — 2.8 to 3.1 million across scenarios — at a total undiscounted capital spend of £16.9 to £20.7 billion.
£5,400 is the figure the government response attaches to the policy as finally confirmed. The final package is not the modelled option: it raised the cap to £10,000, added a property-value-adjustment exemption and set ten-year validity on the main exemptions — all changes that move an average spend.
The honest reading is that government’s own central estimate for the confirmed policy is around £5,400 per property, that the consultation-stage modelling of the preferred option ran higher at £6,100–£6,800, and that both are averages across three million wildly different buildings. A 1930s solid-wall terrace and a 2005 flat do not sit anywhere near the same number, and neither figure is a quote for your property.
The cap is £10,000 per property over a ten-year period, and what counts towards it is broader than landlords usually expect.
The ten-year window has already started. Qualifying spend on relevant energy efficiency measures counts towards the cap from 1 October 2025 — five years before the 2030 compliance deadline itself. Work done now is not too early; it is already on the clock.
Counts towards the cap: spending on relevant energy efficiency improvements, the cost of EPCs, and — importantly — third-party funding you receive, including grants such as ECO4 and Warm Homes grants. A grant that pays for work does not leave your own cap untouched; it consumes it.
Does not count: Boiler Upgrade Scheme grants are excluded from the cap.
Properties under £100,000 have a lower cap. The government response confirms a Property Value Adjustment exemption: for a property valued below £100,000, the cap is 10% of the property’s value rather than the flat £10,000.
The reason this matters: if you assumed grant-funded work was “free” against the cap and left your own spend for later, you may reach the £10,000 ceiling sooner than planned — which is a worse position if you were relying on your own spend to reach the standard, and a better one if you were relying on reaching the cap to claim an exemption. Either way it changes the arithmetic.
Exemptions are not automatic. They are registered on the PRS Exemptions Register, they require evidence, and they expire. The register is publicly searchable.
Under the confirmed 2030 regime the main categories are: the cost cap exemption (you have spent £10,000 without reaching the standard), a property value adjustment or affordability exemption, a negative impacts exemption, an all relevant improvements made exemption, a solid wall insulation exemption, a third-party consent exemption — where a tenant, freeholder or planning authority withholds consent — and a temporary new landlord exemption.
The three headline ones — cost cap, property value adjustment and negative impacts — run for ten years under the new regime, against five years for most exemptions today. The new-landlord exemption remains a short bridge at six months, intended to give someone who has just acquired a tenanted property time to act, not a standing shelter.
The statutory instrument. It has not been laid. Government stated an intention to seek to lay it with a view to force in 2027. Until it exists, the enforceable detail — definitions, evidence requirements, the precise metric thresholds — is not fixed.
The new EPC metric thresholds. The dual-metric structure is confirmed; what precise fabric performance score constitutes the standard for a given property type is a matter for the new EPC regime and the instrument, not something anyone can currently tell you for your specific house.
Whether your current C carries across. Beyond the grandparenting route above, nobody can currently convert today’s rating into tomorrow’s dual-metric result for you. Anyone offering a definitive 2030 assessment today is selling certainty that does not exist yet.
1. Find out where each property actually sits. Not what you assume — the current certificate, its band, and crucially its expiry date. That expiry date is what the grandparenting provision turns on.
2. If a property is at D and close to C, look hard at doing that work before 1 October 2029. This is the time-critical one. A C rating registered under the current system before that date holds until the certificate expires. After it, you are into the new dual-metric standard.
3. Get a proper assessment of fabric, not just a rating. Because fabric performance is the primary metric, insulation is where the 2030 standard bites hardest. A retrofit assessment that tells you about walls, roof and floor is more useful for planning than the headline band.
4. Check what grant funding you are eligible for — and remember it consumes your cap. Grants are worth having; just plan for their effect on the £10,000 arithmetic rather than being surprised by it.
5. Budget against the property’s income, not the average. £5,400 or £6,800 means something very different on a property yielding 4% than on one yielding 9%. Our rental yield index ranks gross yield across 294 English local authorities and our city rent guides give the rent behind it — both official, sourced and dated. We are not going to invent a payback period for you, but the denominator is free to look up.
When exactly do I need to meet EPC C? 1 October 2030, for all tenancies. There is a single compliance date, not a staged one.
My property is already EPC C. Am I done? Not automatically. The 2030 standard is measured against new EPC metrics — fabric performance, plus either smart readiness or heating system — rather than today’s single rating. However, a property scoring C or above on the current Energy Efficiency Rating before 1 October 2029 stays compliant until that certificate expires.
How much will I have to spend? Capped at £10,000 per property over ten years. Government’s central estimate for the confirmed policy is about £5,400 average per property; the consultation-stage options assessment modelled £6,100–£6,800 for the preferred option. Both are averages across around three million very different properties.
What if I spend £10,000 and still do not reach C? You can register a cost-cap exemption, valid for ten years, and continue letting the property.
Do grants count towards the £10,000 cap? Yes for most third-party funding, including ECO4 and Warm Homes grants. Boiler Upgrade Scheme grants are excluded.
What is the penalty for not complying? Up to £30,000 per property per breach under the amended regulations — against a £5,000 total per property today.
Is this law yet? The policy is confirmed; the statutory instrument that implements it has not been laid. Government aims for it to come into force in 2027.
