EPC C by 2030: The Compliance Runway Landlords Should Start Now

EPC C by 2030: The Compliance Runway Landlords Should Start Now

This article is for general information purposes only and does not constitute legal advice. Landlords should seek independent legal advice for their specific circumstances. It focuses on England; the underlying energy policy covers England and Wales, and Welsh landlords should check guidance specific to Wales.

The current rule has not changed yet

Right now, a landlord in England cannot lawfully let most properties with an Energy Performance Certificate (EPC) rating below band E. That minimum standard comes from the Energy Efficiency (Private Rented Property) (England and Wales) Regulations 2015, and it has applied to all existing tenancies since 1 April 2020. A landlord who cannot reach band E can register an exemption on the PRS Exemptions Register, subject to conditions, including a current cost cap of £3,500. The maximum penalty for letting in breach is currently up to £5,000 per property.

That is today's law, and it remains in force. The headline change landlords keep hearing about, the move to EPC C, is not yet law. It is confirmed government policy, and the direction is now clear, but the regulations that will deliver it have not yet been made.

What the government has confirmed

On 21 January 2026, alongside the Warm Homes Plan, the government published its response to the consultation Improving the energy performance of privately rented homes. The response confirms the intention to raise the minimum standard for privately rented homes in England and Wales to the equivalent of EPC C.

Two points from that response matter most for planning. First, there will be a single compliance date. The earlier idea of catching new tenancies in 2028 and existing tenancies in 2030 has been dropped. The government has said landlords will need to meet the higher standard by 1 October 2030 for all tenancies. Second, the government intends to seek the necessary powers and then lay a statutory instrument to amend the 2015 Regulations, with the aim of it coming into force in 2027. Until that instrument is made, the legal minimum stays at band E.

Because the policy is confirmed but the detailed regulations are still to come, some specifics could still shift. Landlords are advised to treat 1 October 2030 as a firm planning horizon while watching for the final rules.

Why band C will not mean what it means today

The letter "C" is doing a lot of work, and it is about to change meaning. The government has confirmed that EPC methodology is being reformed under the Home Energy Model, replacing the single Energy Efficiency Rating used today with several new metrics.

Under the confirmed approach, compliance will be measured against a dual-metric standard. Landlords will first be expected to invest towards a primary fabric performance metric, which reflects how well the building envelope retains heat, alongside a secondary metric such as the heating system or smart readiness. In plain terms, reaching "C" will be less about a single headline number and more about the fabric of the building and how it is heated.

The exact band boundaries for the new metrics are still being finalised. This is one reason it is generally understood that landlords should not rush into major works before the final assessment method is settled, unless a measure is sensible on its own terms.

There is a helpful transitional point. The government has said that properties scoring band C or better on the current Energy Efficiency Rating before 1 October 2029 will be treated as compliant until that EPC expires or is replaced. A property that reaches C under today's system in good time can therefore buy itself a longer runway.

The money: cost cap and penalties

The financial framework has firmed up too. The government has confirmed a cost cap of £10,000 per property, reduced from the £15,000 figure floated during the consultation. If required works exceed the cap, a landlord will be able to register a cost cap exemption. Spending from 1 October 2025 is expected to count towards that cap, so improvement costs incurred now are not necessarily wasted.

Enforcement is set to become far more significant. The government has confirmed its intention to raise the maximum penalty for breaching the standard to up to £30,000 per property per breach, a substantial increase on today's £5,000 ceiling. Councils will also be able to use the incoming PRS Database, introduced by the Renters' Rights Act 2025, to identify which properties are let and cross-check them against the energy performance and exemptions registers.

The runway starts now

Four and a half years can feel like plenty, but the practical runway is shorter than it looks. Fabric measures such as insulation often need surveys, quotes, access, and sometimes planning or freeholder consent. Good installers get busier as a deadline approaches. A landlord who commissions an assessment early, plans works across the runway rather than in a single rush, and keeps clear records of every improvement will be in a far stronger position than one who waits for 2029.

The record keeping matters as much as the works themselves. When a council checks compliance, or when a landlord relies on an exemption, the question is always the same: what was done, when, and what does the evidence show? Keeping EPCs, quotes, invoices, and improvement records in one dated, organised place turns a future scramble into a simple lookup.
