EPC C Target 2030 When the Requirement Starts and What It Costs
If you let a property in England or Wales, you need to know about the new minimum energy efficiency standard coming into force. The government has confirmed that from 2030, all new tenancies must have an Energy Performance Certificate (EPC) rating of C or above.
Landlords in England and Wales must achieve EPC C for new tenancies by 2030 and existing tenancies by 2032. Average upgrade costs range from £5,000 to £15,000 per property, with non-compliance penalties up to £30,000 per breach. Compare improvement options now.
- New tenancies need EPC C by 2030, existing by 2032.
- 1.2 million PRS properties in England and Wales are below C.
- Pre-1919 homes hardest hit: 60% still at D or lower.
- Average improvement costs £5,000 to £15,000 per property.
- Non-compliance penalty up to £30,000 per property per breach.

The minimum EPC C requirement for new tenancies begins in 2030, with existing tenancies following by 2032. Current EPC D or E rated properties will need improvements costing between £5,000 and £15,000 on average, according to the Department for Energy Security and Net Zero (DESNZ) consultation response published in 2026 (DESNZ, 2026). Failure to comply will result in a civil penalty of up to £30,000 per property, per breach (GOV.UK, 2026).
How Many Landlords Currently Do Not Meet the EPC C Standard
As of 2026, approximately 1.2 million privately rented properties in England and Wales are rated EPC D or below. This represents about 30% of the total private rented sector stock, based on Ministry of Housing, Communities and Local Government data from the English Housing Survey 2025–2026 (MHCLG, 2026).
Properties built before 1919 are disproportionately affected, with 60% still at EPC D or lower, according to the DESNZ impact assessment published in 2026 (DESNZ, 2026). This means landlords with older housing stock face the biggest challenge and the highest costs to reach compliance.
Quick Numbers EPC C Target 2030 Cost and Saving Table
| Improvement type | Average cost per property | Annual energy saving (GBP) |
|---|---|---|
| Cavity wall insulation | £800–£1,500 | £200–£400 |
| Loft insulation (top-up to 300mm) | £300–£500 | £100–£200 |
| Solid wall insulation (internal) | £4,000–£8,000 | £300–£600 |
| Double glazing (replacement) | £3,000–£7,000 | £150–£300 |
| Air source heat pump | £9,000–£14,000 | £400–£700 |
| Solar PV (4kW system) | £5,000–£6,500 | £200–£400 |
Costs are drawn from the Energy Saving Trust renovation and retrofit cost guide, 2026 edition (EST, 2026). Savings are based on EST verified data for a typical three-bedroom semi-detached home (EST, 2026). Actual costs and savings vary by property size, construction type, and existing heating system.
The Direct Answer to “What Does EPC C Target 2030 Mean for Landlords?”
From 1 January 2030, landlords in England and Wales cannot grant a new tenancy for a property with an EPC rating below C. From 1 January 2032, all existing tenancies must also meet the EPC C minimum.
The requirement applies to all privately rented properties, with no exemption for small landlords or single-property owners. The maximum cost cap per property is £15,000 (including VAT) for compliance improvements, as confirmed in the DESNZ implementation plan published in 2026 (DESNZ, 2026). If your property currently has an EPC rating of D or E, you need to budget for improvements now, not wait until 2029.
Eligibility for the £15,000 Cost Cap and Exemptions
The cost cap of £15,000 is the maximum a landlord must spend to bring a property to EPC C. Any costs above this allow a five-year exemption. Exemptions are available for listed buildings, properties in conservation areas where improvements would unacceptably alter character, and where structural surveys show insulation would cause damp.
Landlords must register exemptions on the PRS Exemptions Register within 10 days of the compliance deadline, according to government guidance published in 2026 (GOV.UK, 2026). Third-party consent exemptions also apply if a tenant or planning authority refuses necessary works. You must keep evidence of the refusal to register a valid exemption.

How to Verify Your Installer MCS and TrustMark Certification
All insulation and heat pump installations must be carried out by an MCS-certified (Microgeneration Certification Scheme) contractor for the work to count toward EPC improvement. The MCS Register confirms this requirement in its 2026 standards (MCS, 2026).
For general energy efficiency improvements, installers must hold TrustMark registration with a relevant trading scheme. For windows, the installer should be FENSA registered. For boilers and gas work, they must be on the Gas Safe Register. Landlords must retain certificates of installation and certification for at least five years after compliance, as the EPC assessor will verify the works during the post-improvement EPC assessment (TrustMark, 2026).
What the £15,000 Cost Cap Actually Covers and What It Does Not
The cap covers the total cost of all energy efficiency improvements needed to reach EPC C, including materials, labour, and VAT. It does not cover decorative or non-essential repairs that happen alongside improvements, such as replastering after internal wall insulation.
The cap is per property, not per landlord, meaning a landlord with 10 properties must spend up to £150,000 total. If a property cannot reach EPC C even after spending £15,000, the landlord must register a high-cost exemption valid for five years, as per DESNZ cost cap guidance published in 2026 (DESNZ, 2026).

Start planning now. Get an updated EPC assessment for any property currently rated D or E. Your assessor can provide a recommendation report showing which improvements will have the biggest impact on the rating. Prioritise loft and cavity wall insulation first, as these are the lowest cost measures with the fastest payback.

Costs average between £5,000 and £15,000 per property according to the DESNZ consultation response (DESNZ, 2026). Common improvements include cavity wall insulation (£800–£1,500) and loft insulation (£300–£500).

Approximately 70% of privately rented properties in England and Wales already meet EPC C or above, leaving about 1.2 million properties (30%) below the target (MHCLG, 2026).
Loft insulation top-up (£300–£500) and cavity wall insulation (£800–£1,500) offer the fastest payback, saving £100–£400 per year each according to Energy Saving Trust data.
