The government's January 2026 response confirms the direction of travel for privately rented homes in England: all properties must reach EPC Band C by 1 October 2030, across new and existing tenancies.
What landlords need to know
The policy is confirmed but the higher standard is not yet in force. The current legal minimum remains Band E, giving landlords time to plan improvements and spread the work.
The regulations will require up to £10,000 per property to reach Band C. Qualifying expenditure from 1 October 2025 counts toward the cap. If the property still cannot reach Band C after the full cap has been spent, landlords can register a 10-year cost-cap exemption.
Why secondary glazing can suit period rentals
Replacement windows may not be appropriate in listed buildings and conservation areas. Internal secondary glazing preserves original joinery while adding a discreet, reversible layer that can improve thermal performance. A property-specific EPC assessment is still essential because the final rating depends on the whole building.
Book a landlord EPC assessment to discuss your property and priorities.
