EPC C by 2030: the complete timeline every landlord needs
Landlord regulations are changing - and the worst time to learn the detail is the year it bites. Here's the full picture, plainly, so you can plan.
The short version
The government has confirmed that privately rented homes in England and Wales will need to meet a new C-equivalent standard by 1 October 2030, with a £10,000 per-property spend cap and fines up to £30,000.
Here's how it plays out, year by year.
2025–2026: the groundwork
Spend on qualifying improvements made from 1 October 2025 already counts towards your £10,000 cap.
New-style EPCs - with the new metrics that the C standard will be measured against - are expected to start appearing from around late 2026, subject to confirmation.
In 2026 the government also responds to consultations on the new EPC regime and the Home Energy Model (the new calculation method).
What to do: don't wait, but don't rush into retrofits blind either. The single best action now is to know each property's current rating and expiry dates.
2027: the law firms up
Legislation to raise the standard is expected to come into force during 2027.
This is when the £30,000 maximum fine and the new compliance framework get legal teeth.
What to do: for any property clearly below C, get a plan in place in 2027 while assessors and installers are still readily available. Come 2029–2030, demand will surge.
1 October 2029: the golden deadline
If a property scores C or above on its EPC before this date, it's treated as compliant with the new standard until that EPC expires or is replaced.
What to do: treat October 2029 as your real deadline, not 2030. Getting to C before this date is the single most valuable move you can make.
1 October 2030: full compliance
All tenancies must meet the standard, unless you've used the grandparenting clause or registered a valid exemption.
Local authorities begin enforcement - with fines up to £30,000 per property, per breach.
The three keys to staying ahead
Know your current position. A surprising number of portfolios contain expired or missing EPCs - each one a potential breach and a wasted chance to count spend.
Prioritise by cost-to-reach-C. Two identical-looking houses can have very different routes to C. Focus cash where it moves a band.
Evidence everything. Keep receipts, guarantees, and post-work EPCs. Every qualifying pound, every exemption, every certificate matters.
The simplest rule of thumb
Get to C before October 2029, and you've bought yourself years of certainty. Leave it later, and you're working against a deadline with the whole market chasing the same tradespeople.
That's why the landlords who sleep easiest are the ones who start with a simple question: where does my portfolio actually stand?
