The government will require every rental property in England and Wales to have an EPC rating of C by 2030, a rule that affects an estimated 1.6 million homes currently rated D or below. For the 4.6 million private renters in the UK, that could mean lower bills and warmer winters. For landlords, it means a bill they cannot ignore.
As reported by CBRE UK, the timeline is not yet final but the direction is clear: the current exemption system, which allows landlords to avoid upgrades if costs exceed £3,500, will be tightened. The cap is expected to rise to £10,000 per property, and the loophole that lets landlords register a seven-year exemption by simply getting three quotes will likely close.
Who qualifies, and who doesn’t
The rules apply to all privately rented properties in England and Wales. Social housing has separate targets: EPC C by 2030 for new tenancies, 2035 for all. Owner-occupiers face no legal deadline, but the same upgrades will be needed if they want to sell: from 2028, estate agents may be required to display EPC ratings on listings, and mortgage lenders are already pricing in lower rates for A–C rated homes.
The catch is cost. A typical 3-bed semi with solid walls, single glazing, and an old gas boiler needs roughly £12,000–£18,000 of work to reach a C rating. That includes cavity wall insulation (£2,500–£4,500), loft insulation top-up (£500–£1,000), double glazing (£4,000–£8,000), and a heat pump or boiler upgrade (£7,000–£13,000 after the £7,500 Boiler Upgrade Scheme grant). Landlords who cannot afford the work can apply for an exemption, but the bar will be higher than today.
What it costs a typical 3-bed semi
Ofgem data shows the average household with an EPC D rating pays £1,850 a year on energy. A C-rated home pays £1,450, a saving of £400. An A-rated home pays £1,100. Over a five-year period, the upgrade pays for itself in reduced bills, but the upfront cost is the barrier.
The government’s own impact assessment, published in 2021, estimated that 85% of landlords would need to spend between £5,000 and £15,000 per property. Only 15% would get away with less than £5,000. The Great British Insulation Scheme closed on 31 March 2026. It funded insulation measures only and never covered windows or glazing.
When to act, and why early matters
Installers are already stretched. The Microgeneration Certification Scheme (MCS) reports that heat pump installer numbers have doubled since 2021, but demand is rising faster. Landlords who wait until 2028 will face longer lead times and higher prices. The Energy Saving Trust recommends getting an EPC assessment now, then prioritising the cheapest measures first: loft insulation, draught-proofing, and cavity wall fill. These alone can lift a D to a C in many homes.
For owner-occupiers, the same logic applies. Mortgage lenders including Nationwide and Barclays now offer lower rates for homes with EPC C or above, typically 0.1–0.3% off the interest rate, worth £300–£900 a year on a £200,000 mortgage. The green premium is real, and it’s growing.
But the biggest risk is doing nothing. The government has signalled that non-compliant landlords face fines of up to £30,000 under the new MEES rules. That is more than the cost of the upgrade. For tenants, the cost is colder homes and higher bills, an estimated £700 a year extra for those living in an EPC F or G property compared with a C.
Households on standard variable tariffs can check their EPC rating for free at gov.uk. Landlords should book a new assessment if theirs is more than 10 years old. The deadline is 2030, but the smart money moves now.
Frequently Asked Questions
Landlords will be unable to issue new tenancies from 2028, and all tenancies must comply by 2030. Fines can reach £30,000 per property. Exemptions will be available only if the cost of upgrades exceeds £10,000 and all cost-effective measures have been exhausted.
Yes, but mostly for low-income households. The Great British Insulation Scheme closed on 31 March 2026. It funded insulation measures only and never covered windows or glazing. Landlords with higher incomes must cover costs themselves, but can claim capital allowances against tax.
