Every rental property in England and Wales must have a valid EPC rated band E or above. This rule has applied to all tenancies, not just new ones, since April 2020. Fines reach £30,000 per property. The proposed upgrade to band C by 2028–2030 is the biggest change since MEES launched. London landlords who act now avoid the installer bottleneck that's coming.

| Maximum fine (short breach) | £5,000 per property |

The obligation attaches to the act of letting, granting, renewing, or continuing a tenancy. A statutory periodic tenancy (rolling over after a fixed term) is treated as a continuation of the existing tenancy for MEES purposes.
Local authority enforcement in London has intensified since 2023. Tower Hamlets, Newham, Hackney, and Southwark have run active compliance campaigns. Enforcement details are published on a public database, reputational risk is real alongside the financial penalties.
Step 1, Know your portfolio's current ratings
Check the government EPC register (find-energy-certificate.service.gov.uk) for every property. Flags requiring immediate action:
- Rating F or G: The property cannot legally be let. If a tenancy is active, you are currently in breach.
- Expiring certificate: Renew before it expires, a valid in-date EPC is required to demonstrate compliance.
- No EPC on register: Commission an assessment before the next letting (common for pre-2008 properties).
- Rating D or lower: Start planning improvements now for the proposed 2028 C deadline.
We offer bulk assessment scheduling across all London boroughs. Contact us to discuss portfolio programmes.
Step 2, Understand your property types
Improvement costs and feasibility vary enormously by construction. Categorise your portfolio:
Cavity-wall properties (1920–1990)
Found across outer London, Ealing, Croydon, Bromley, Enfield, Barnet, Sutton, Havering, and Bexley. These are the easiest to improve:
- Cavity wall insulation: £400–£800, adds 5–10 SAP points
- Loft insulation to 270mm: £400–£600, adds 4–8 SAP points
- LED lighting: £80–£150, adds 1–4 SAP points
- Total to reach C from D: typically £800–£2,000
Many qualify for ECO4 or GBIS funding, potentially free. Prioritise these now.
Victorian and Edwardian solid-wall properties (pre-1919)
The dominant type in inner London, Hackney, Islington, Lambeth, Wandsworth, Southwark, Tower Hamlets, Newham. These require more significant intervention:
- External wall insulation (EWI): £12,000–£18,000, highest impact, planning/conservation area check required
- Internal wall insulation: £8,000–£14,000, loses floor area
- Solar PV 3–4kWp: £5,000–£9,000, often the most cost-effective single route to C
- LED + loft + heating controls combined: may reach C from high D (SAP 65+) without wall works
Get your exact SAP score first. A Victorian terrace at D66 may reach C with LEDs and loft insulation. One at D55 almost certainly needs wall insulation or solar PV. Our assessment tells you this for £49–£79.
Post-war flats and maisonettes (1945–1980)
Common in Tower Hamlets, Lambeth, Southwark, Newham, Hackney, and Brent. The heating system is often the critical factor:
- Electric storage heaters: typically D or E, the heating system is the main lever
- Communal gas heat network: often C already
- Individual gas boiler: usually D, achievable to C with insulation
For flats with storage heaters, replacing with a modern gas combi (if gas is available) or heat pump is the most impactful single measure. This may require building consent and freeholder involvement.

Step 3, Prioritise improvements strategically
Priority order:
- F/G properties first, actively non-compliant, improvement is mandatory
- E properties next, plan for the proposed C deadline; improving between tenancies is far cheaper than mid-tenancy
- D properties third, the proposed C standard makes D the new compliance risk from 2028
- Use ECO4 wherever eligible, the scheme is time-limited; apply now for any tenant receiving means-tested benefits
- Batch by property type, five cavity-wall semis in the same area can be surveyed and insulated in a single contractor visit
Step 4, Exemptions: when and how to use them
Exemptions are narrow and must be registered on the PRS Exemptions Register before you continue letting. An unregistered exemption is not valid.
Cost cap exemption: All relevant improvements would cost more than £3,500 (the current cap under the E standard; expected to rise to £15,000 under the proposed C standard). You must get three installer quotes, carry out all improvements that collectively cost under £3,500, then register the exemption with evidence.
Consent exemption: A tenant, lender, or planning authority has refused consent in writing. Document everything.
Devaluation exemption: An independent surveyor confirms the works would reduce market value by more than 5%.
Listed building exemption: Applies where compliance would unacceptably alter the character of a listed building.
Common mistakes: getting only one quote, not completing sub-cap measures before claiming the exemption, letting the five-year exemption lapse without re-registering.
Step 5, The proposed C standard: planning now
The C standard is not yet law but the 2028 planning horizon is real. Key actions:
- Know your scores, commission assessments for any property without a current EPC
- Model improvement costs per property type, cavity-wall vs solid-wall costs differ by 5–10×
- Check ECO4 eligibility, apply before the scheme window closes in 2026
- Schedule works between tenancies, insulation and wall works in an empty property are faster and cheaper
- Factor into purchase decisions, an F-rated Victorian terrace needs an £8,000–£18,000 improvement budget

Getting assessments across your portfolio
For London landlords managing multiple properties, we recommend a portfolio sweep: a bulk EPC assessment programme to confirm all current ratings in one round. We can assess multiple properties in a single day if geographically clustered.
All 32 London boroughs are covered. See our landlords page for service details, our pricing page for per-property costs, or contact us to arrange portfolio scheduling.
For the full legal detail on MEES, see our MEES regulations guide. For individual improvement costs, see our EPC improvement guide.
Frequently asked questions
- No. An EPC is valid for 10 years and you can use the same certificate for consecutive tenancies within that period. However, if the certificate expires you must commission a new one before the next letting. If you've made improvements, a new assessment will show the updated rating.
- The same MEES standard applies to HMOs as to standard residential lettings: band E or above currently, rising to C under the proposed upgrade. HMO licence renewal applications increasingly require a valid and MEES-compliant EPC.
- A tenant formally refusing reasonable access for improvement works qualifies for a 'consent refused' MEES exemption, which can be registered on the PRS Exemptions Register. Document the refusal carefully, date, method, written confirmation, and register the exemption before the next letting.
- Short-term holiday lets for fewer than four months are generally exempt from MEES. However, if you switch between short-term and long-term letting the property must comply before being let on a long-term basis. Maintaining MEES compliance is the safest approach.
- Under the proposed regime you would be unable to grant a new tenancy until the property reaches C or registers a valid exemption. Existing tenancies could continue until 2030. Non-compliance would attract fines under the updated penalty regime, expected to be significantly higher than the current £30,000 cap.
- Indirectly, a higher-rated property supports a higher market rent, and there is increasing evidence that tenants in London prefer C-rated or above properties. You cannot pass the direct cost of improvement works to a sitting tenant under a fixed-term AST, but you can factor expected improvement costs into rent when re-letting.
