Mon 09 Feb 2026
Sara Grey, Lettings Manager
Energy efficiency has been firmly back in the spotlight this month, with the Government confirming new minimum standards for rental properties across England and Wales.
On 21 January 2026, it was confirmed that all privately rented homes must reach an EPC rating of C by 1 October 2030, unless a valid exemption applies. While the deadline may feel distant, the detail behind the announcement makes it clear that landlords should start planning now.
This article breaks down what we know so far - and what Surrey landlords should be thinking about next.
Crucially, the way EPCs are calculated is set to change.
The Government has launched a further consultation - closing on 18 March 2026 - on a new assessment system known as the Home Energy Model (HEM). This will replace the current EPC methodology and introduce new metrics for measuring energy efficiency. That means:

What’s Been Confirmed
Under the updated proposals:- All rented homes must achieve EPC C by 1 October 2030 The requirement applies to all tenancies, not just new lets
- A £10,000 cost cap will apply to required improvements
- Exemptions will still exist, but they must be formally registered
Why This Is More Than Just a Deadline
Change Although many headlines have focused on the delay to 2030 and the £10,000 cap, there is far more to this reform than a simple date shift.Crucially, the way EPCs are calculated is set to change.
The Government has launched a further consultation - closing on 18 March 2026 - on a new assessment system known as the Home Energy Model (HEM). This will replace the current EPC methodology and introduce new metrics for measuring energy efficiency. That means:
- EPCs issued under the current system will not last forever
- EPCs produced before 2029 are likely to expire under the new framework
- Landlords may need new EPC assessments even if their current certificate looks acceptable today
Transition Arrangements:
What Happens to Existing EPCs?- Under the current proposals: Existing EPCs will remain valid until they expire
- However, once expired, new EPCs will be issued using the updated HEM metrics
- Properties that currently score well may perform differently under the new model
What Will Landlords Need to Do?
While final details are still being confirmed, landlords should expect to focus on: Improving heating systems and controls- Upgrading insulation where feasible
- Addressing draughts and thermal inefficiencies
- Considering renewable or low-carbon technologies where appropriate
Why Early Planning Matters for Surrey Landlords
In Surrey, where many rental properties are older, character homes, early planning is particularly important. Waiting until the late 2020s could mean:- Limited contractor availability
- Rising costs due to increased demand
- Pressure to complete upgrades quickly to remain compliant
- Spread improvement costs over several years
- Plan works around void periods
- Avoid last-minute compliance issues
