EPC for Landlords 2026: Minimum E Rating, Costs and Proposed C Band by 2028

Current EPC requirements for landlords (2026)

Energy Performance Certificates are mandatory for all residential lettings in the UK. The minimum standard varies by nation and is subject to ongoing policy evolution.

England and Wales

In England, the private rented sector must meet minimum EPC rating E since 1 April 2020. This applies to all new lettings and extended the previous regulations which applied only to new lettings from April 2018.

Wales implemented the same E rating minimum from 1 April 2020, aligning with England.

Scotland

Scotland implemented EPC D as the minimum rating for the private rented sector, a higher standard than England and Wales. This requirement has been in place for lettings from 1 April 2021 onwards. The Scottish government has signalled further tightening to a C rating but this is not yet implemented as of June 2026.

Northern Ireland

Northern Ireland currently allows EPC F as the minimum rating, but policy changes are under consultation. The aim is to move toward EPC E to align with Great Britain by 2027-2028, though this has been delayed from originally planned timelines.

What does each EPC rating mean?

The EPC scale runs from A (most efficient) to G (least efficient). The ratings reflect the property's expected annual energy costs based on heating, cooling, lighting, and hot water.

EPC A: GBP 0-30 annual running costs (extremely rare, nearly zero-carbon)

EPC B: GBP 30-80 annual running costs (new houses, modern standards)

EPC C: GBP 80-200 annual running costs (good modern standard, well-insulated)

EPC D: GBP 200-350 annual running costs (average modern standard, typical 1990s-2000s builds)

EPC E: GBP 350-600 annual running costs (below average, pre-1990 builds, limited insulation)

EPC F: GBP 600-1,200 annual running costs (poor, older properties, draughty)

EPC G: GBP 1,200+ annual running costs (very poor, rarely lettable)

A property with EPC E has annual energy running costs estimated at GBP 350-600, depending on occupancy and usage patterns.

The proposed minimum C rating from 2028

The UK government has consulted on raising the minimum rating to EPC C for private rented properties, with implementation planned for:

• 1 April 2028: Minimum C for new lettings
• 1 April 2029: Minimum C for existing tenancies

However, as of June 2026, this is not yet confirmed law. The proposal requires parliamentary approval and faces resistance from landlord organisations due to upgrade costs. There is no certainty this will proceed on the originally planned timeline.

Landlords should monitor government announcements, as changes may be delayed or modified. The proposal includes exemptions for properties where insulation would be technically unsuitable or listed building constraints apply.

Estimated impact if C rating becomes law

If the C rating is implemented as proposed, approximately 2 million properties in the private rented sector would require upgrades. The average improvement cost is estimated at GBP 5,000-15,000 per property, totalling approximately GBP 10-30 billion across the sector.

This would significantly impact rental yields and investment decisions, as upgrade costs cannot typically be recovered through rent increases.

How to get an EPC and cost breakdown

Obtaining an EPC

EPC assessments are conducted by accredited energy surveyors. To obtain an EPC:

1. Contact an accredited assessor via the Qualified Energy Assessor (QEA) database or request quotes from local surveyors
2. Schedule a property inspection (typically 30 minutes to 1 hour for flats; up to 2 hours for detached houses)
3. Assessor generates the EPC report within 5-10 working days
4. Register on national EPC database (automatically by the assessor)
5. Receive the EPC certificate (valid for 10 years)

EPC cost by property type

Example: A 3-bed semi-detached house costs GBP 100-120 for EPC assessment in most UK regions.

EPC improvements and upgrade costs

Moving from E to D (1-point improvement) typically requires modest measures. Moving from E to C (2-point improvement) requires more substantial investment.

Loft insulation

• Cost: GBP 800-1,200 for 200-300 mm loft insulation
• EPC impact: +1-2 points (E→D or D→C depending on baseline)
• ROI: Payback in 3-4 years through energy savings

Wall insulation

Cavity wall insulation (if applicable):

• Cost: GBP 1,500-3,000
• EPC impact: +1-2 points
• ROI: Payback in 5-6 years

External wall insulation (more expensive):

• Cost: GBP 10,000-20,000
• EPC impact: +2-4 points
• ROI: Payback in 8-10 years, requires planning permission

Boiler replacement

• Cost: GBP 2,500-4,500 for modern condensing boiler installation
• EPC impact: +1-2 points
• ROI: Payback in 6-8 years through reduced fuel consumption

Solar panels (PV)

• Cost: GBP 5,000-8,000 for 3-4 kW system
• EPC impact: +2-3 points
• ROI: Payback in 7-10 years, plus Feed-In Tariff/export revenue

Heat pump installation

• Cost: GBP 8,000-15,000 for air-source or ground-source heat pump
• EPC impact: +3-4 points
• ROI: Payback in 10+ years, but increasingly favoured by government policy

Double glazing

• Cost: GBP 3,000-6,000 (full replacement)
• EPC impact: +0.5-1 point (modest impact)
• ROI: Longer payback, less effective than insulation

Combined upgrade scenario: E→C rating

To move from EPC E to C reliably requires multiple measures:

• Loft insulation: GBP 1,000
• Cavity wall insulation: GBP 2,000
• Modern boiler: GBP 3,500
• Solar panels (3kW): GBP 6,500
• Total: GBP 13,000

Landlords might alternatively target:

• Boiler replacement + loft + cavity: GBP 6,500 (possibly achieves D)
• Boiler + loft + cavity + solar: GBP 13,000 (likely achieves C)

The exact upgrade path depends on the property's current EPC report recommendations.

Penalties for non-compliance

Letting a property below the minimum EPC rating incurs penalties:

England and Wales:

• First breach: Penalty up to GBP 5,000 per property
• Further breach: Additional GBP 5,000 per breach
• Letting agent breach: Letting agents can be fined up to GBP 5,000 for arranging lettings below minimum rating

Scotland:

• Similar penalty structure with powers to fine up to GBP 50,000 for serious breaches

Penalties are enforced by local authority environmental health teams. Enforcement is sporadic but increasing, with councils in some areas actively testing the private rented sector for compliance.

Exemptions from EPC requirements

Certain properties are exempt from EPC requirements:

✓ Listed buildings - if insulation measures would damage historic character (requires exemption registration)

✓ Residential buildings with total useful floor area < 50 m² (applies to some studio flats)

✓ Properties temporarily rented (< 4 months per year)

✓ Properties rented to owner's family members (some jurisdictions)

✓ Commercial properties with residential component (if < 25% residential)

Claiming exemption for listed buildings requires registering with the local authority and demonstrating why energy efficiency measures would damage the building.

Practical steps for landlords in 2026

If currently lettable (EPC E or better):

1. Obtain current EPC (if not done in last 10 years) -- cost GBP 60-120
2. Register on national EPC database
3. Monitor policy changes regarding proposed C rating (implement timescale unclear)

If currently below minimum (EPC F or G):

1. Stop lettings immediately (legal liability)
2. Obtain EPC (GBP 60-120)
3. Request improvement recommendations from EPC report
4. Plan upgrades (prioritise cost-effective measures: boiler, loft, insulation)
5. Budget GBP 5,000-15,000 for E→D or E→C upgrade

If preparing for 2028 C rating requirement:

1. Current E-rated property: Plan upgrade now (GBP 8,000-15,000) to avoid last-minute rush
2. Current D-rated property: Minor upgrades only (GBP 2,000-5,000)
3. Explore funding: Government grant schemes (e.g., Energy Company Obligation -- ECO) may fund some measures

Energy Company Obligation (ECO) and grant funding

The government's Energy Company Obligation may fund insulation or heating improvements for eligible landlord properties. Grant funding varies by scheme and eligibility.

Typical ECO funding:

• Cavity wall insulation: Up to 100% funded
• Loft insulation: Up to 100% funded
• Boiler replacement: Partial funding (GBP 500-2,000)

Eligibility depends on property location, EPC rating, and fuel poverty status. Landlords should contact local authority or ECO-approved providers for assessment.

Financial planning for E→C upgrades

Investment required: GBP 5,000-20,000 Time frame: 1-2 years (if 2028 implementation confirmed) Payback period: 8-15 years through fuel savings + rental value preservation Financing options:

• Green mortgage deals (slightly discounted rates)
• Landlord loans (specialist lenders)
• ECO grant funding
• Retained profits

Landlords should factor upgrade costs into investment appraisals and expected yields.

Summary

England and Wales currently require EPC E minimum rating for lettings. A proposed move to EPC C from 2028 is not yet law but should be monitored. EPC assessment costs GBP 60-120, while upgrading to C costs GBP 5,000-20,000. Penalties for non-compliance reach GBP 5,000 per property. Landlords should obtain current EPCs, plan upgrades if required, and monitor government policy announcements for clarity on implementation timescales.
