EPC C by 2028: What Proposed Landlord Rules Mean Now
The government's proposed EPC C minimum for rental properties from 2028 isn't law yet — but landlords who wait to act risk a costly scramble. Here's the sell, upgrade or exempt decision, worked out in numbers.
Why "2028" Is Already Shaping Landlord Decisions
Even though the EPC C requirement for rental properties has not been legislated, it has already become the working assumption most letting agents, mortgage brokers and landlord bodies plan around. The government first floated a 2025 start date, then pushed the proposal back; as of mid-2026 the consultation outcome and final regulations are still awaited, but the direction of travel — a tighter minimum energy rating for the private rented sector — has been consistent for several years.
That matters for a very practical reason: works like external wall insulation, heat pump installation, and full rewiring for improved insulation take months to plan and complete, and skilled retrofit contractors are already in short supply. If the rule is confirmed with only a year or two of lead time, landlords who start planning now will get quotes, financing and contractor slots at a fraction of the cost and hassle of landlords who wait until the deadline is imminent.
The Current Legal Minimum: EPC E
It's worth being precise about what's actually required today. Since April 2020, MEES has required an EPC rating of E or above for both new and continuing residential tenancies in England and Wales. Below E, letting is unlawful unless a valid exemption — for example a high-cost exemption, a "all improvements made" exemption, or a temporary exemption for new landlords — is registered on the PRS Exemptions Register. Landlords should check their current EPC rating (valid for 10 years from issue) before assuming they're already compliant, since many properties haven't been reassessed in years.
The Proposed 2028/2030 Timeline
Under the consultation proposals most widely discussed, the reform would apply in two stages:
| Milestone | Proposed requirement |
|---|---|
| New tenancies from 2028 | EPC C minimum |
| All existing tenancies from 2030 | EPC C minimum |
| Cost cap (proposed, unconfirmed) | Around £10,000 per property, above which a high-cost exemption may apply |
| Penalty for non-compliance (under existing MEES framework) | Up to £30,000 per property |
Treat every figure in that table except the current EPC E minimum as provisional. The final legislation could adjust the dates, the cost cap, or the exemption criteria, and landlord groups have lobbied for a longer lead time given the scale of the retrofit challenge across roughly 4.6 million privately rented homes in England alone.
The Three Choices: Upgrade, Sell, or Plan for an Exemption
Rather than waiting for certainty that may not arrive for another year or two, it helps to frame the decision now as three concrete options.
1. Upgrade now, while you control the timeline. This suits landlords planning to hold the property long-term, where the improvement cost is proportionate to the property's value and achievable rent. Acting early avoids the contractor bottleneck that's likely to build as any confirmed deadline approaches, and may unlock a green mortgage discount in the meantime.
2. Sell before the reform bites. This can make sense for a hard-to-treat property — solid-wall construction, off-gas-grid heating, a listed building with restricted alteration rights — where the upgrade cost would materially exceed the property's value uplift or the landlord's remaining investment horizon. Selling into a market that hasn't yet fully priced in the EPC C requirement may realise more value than selling after the rule (and the visible cost of compliance) is confirmed.
3. Plan for an exemption. If the property genuinely can't reach C within the eventual cost cap — a common issue for solid-wall Victorian and Edwardian terraces — a high-cost or technical exemption may be available once the reformed framework is in force. This isn't a strategy of doing nothing; it typically still requires spending up to the cost cap and gathering evidence (quotes, survey reports) to support the exemption claim.
A Worked Example
Consider a landlord with a 1930s semi, currently EPC D, valued at £280,000 with a rental yield of 5.5% (roughly £15,400/year in rent).
- Retrofit assessment estimate to reach C: loft top-up, cavity wall insulation, and a heat pump replacement for the ageing gas boiler — around £11,000.
- Funding route: a further advance on the buy-to-let mortgage at a green-tariff discount, adding roughly £55/month in interest at current rates.
- Expected outcome: modest rent uplift on the next letting cycle, reduced void risk versus an increasingly EPC-conscious rental market, and full compliance well ahead of any 2028 deadline.
Compare that with a solid-wall Victorian terrace valued at £220,000, currently EPC F, where reaching C is estimated at £22,000 including internal wall insulation and full rewiring. Here, the maths often favours either selling (particularly if the landlord holds other, easier-to-treat properties in the same portfolio) or budgeting for a high-cost exemption once the final cost cap is confirmed.

First, get your current EPC checked — if it's due for renewal (they last 10 years) or you've never had one assessed against the newer, more detailed metric, a fresh assessment gives you a realistic baseline. Second, request a Retrofit Assessment or improvement report that estimates the cost and impact of specific measures for your property, not a generic industry average. Third, if you're financing the works, speak to your mortgage lender or broker about green further-advance products before committing your own cash. Fourth, keep every invoice and quote — if a high-cost exemption becomes available, you'll need evidence of what you've already spent. Finally, revisit your plan whenever the government publishes its final response to the consultation, since the confirmed dates and cost cap will materially change the calculation for marginal cases.

Is EPC C definitely required for rental properties from 2028?
Not yet. The government has consulted on requiring EPC C for new tenancies from 2028 and all tenancies from 2030, but as of mid-2026 this has not been passed into law. The timetable has already slipped once — it was originally floated for 2025 — so landlords should treat 2028 as a working planning assumption rather than a guaranteed date, and keep watching for the final regulations, which will set the confirmed cost cap and exemption rules.
What EPC rating do rental properties need right now, in 2026?
The current legal minimum under the Minimum Energy Efficiency Standards (MEES) is EPC E for both new and continuing tenancies in England and Wales, and has been since April 2020. A property below E generally cannot be lawfully let unless a valid exemption is registered on the PRS Exemptions Register. EPC C is a proposed future tightening of this standard, not the current rule.
How much does it cost to upgrade a property from EPC D or E to C?
It varies hugely by property type and starting point. A well-insulated post-1990s flat might only need loft top-up insulation and LED lighting for a few hundred pounds. A solid-wall Victorian terrace requiring internal or external wall insulation, a heat pump or replacement boiler, and new glazing can run to £10,000-£25,000 or more. Getting a Retrofit Assessment or an EPC improvement report with cost estimates for your specific property is the only reliable way to budget.
Will there be a cost cap so I don't have to spend unlimited money?
Under the 2020 consultation proposals, a cost cap of around £10,000 per property was suggested, above which a landlord could register a high-cost exemption without reaching EPC C. This figure has not been confirmed in final legislation and could change. Do not assume a specific cap figure will survive into the final rules — budget conservatively and revisit your plan once the legislation is confirmed.
What happens if I don't comply once the rules take effect?
Under the existing MEES framework, letting a sub-standard property without a valid exemption can trigger civil penalties of up to £30,000 per property (the exact penalty scales with how long the breach continues and the rateable value in some cases). The proposed EPC C reform is expected to carry similarly serious penalties, since it would operate as an extension of the same MEES enforcement regime rather than a separate scheme.
Should I sell a hard-to-treat property instead of upgrading it?
For some landlords, yes — particularly where a solid-wall or off-gas-grid property would need £15,000-£25,000 of work to reach C, the achievable rent increase doesn't justify that spend, and the landlord is closer to retirement or portfolio downsizing anyway. For others, especially those planning to hold for 10+ years, upgrading now (while contractors have more availability and before the 2028 rush) is usually cheaper than a last-minute scramble. Run the numbers for your specific property rather than following a blanket rule.
Are there grants available to help pay for EPC improvements?
Support has included the Boiler Upgrade Scheme (a grant toward air source and ground source heat pumps), ECO4 (targeted at lower-income and fuel-poor households, which can include some rented properties), and occasionally local council retrofit schemes. Availability, eligibility and funding levels change frequently, so check gov.uk and your local authority for what is currently open before assuming a specific grant will cover your costs.
Does an EPC C property actually rent for more?
Evidence suggests tenants increasingly favour lower-bills properties, and some studies have found a modest rental premium for higher-EPC homes, particularly since the 2022/23 energy price spike raised awareness of running costs. The effect is real but usually modest — a few percent — so the case for upgrading rests more on regulatory compliance and reduced void periods than on a dramatic rent uplift.
Can I remortgage to fund the improvement works?
Many lenders offer green mortgage products with slightly discounted rates for higher-EPC properties, and some allow further advances specifically earmarked for energy efficiency works. A remortgage or further advance is a common way landlords fund a £8,000-£15,000 upgrade without draining cash reserves, though it increases the loan balance and monthly interest cost, so it should be weighed against the property's rental yield.
Does this apply to Scotland and Wales the same way?
Scotland and Wales run separate consultations and are on their own timelines, which have historically diverged from England's. Scotland has discussed its own EPC minimum standards for private rented housing under separate legislation. Always check the specific proposals for the nation your property is in rather than assuming the England timetable applies UK-wide.
