The 2030 deadline means all new tenancies must have an EPC rating of C or higher
If you let a property in England or Wales, you need to know that the rules are tightening. From 2030, you will be legally required to ensure your rental home has an EPC rating of C or higher before you grant a new tenancy or renew an existing one. This is not a distant target; enforcement is expected from April 2030 (DESNZ, 2026).
Landlords must ensure rental properties have an EPC rating of C or higher from 2030 for new tenancies. The average cost to upgrade from band D to C is £2,000 using insulation and draught-proofing. Check your EPC now to plan ahead.
- Check your property's current EPC rating now before 2030.
- 60-65% of rentals already meet EPC band C as of 2026.
- Average cost from band D to C is £2,000 with fabric-first measures.
- Cavity wall insulation costs £500-1,500 and saves £200-400 yearly.

The direct answer is this: you need to check your property’s current EPC rating now, and plan any necessary upgrades before 2030. The average cost to lift a property from band D to band C using the cheapest measures—insulation and draught-proofing—is around £2,000, though costs vary widely.
The current EPC band C compliance rate and what remains
As of 2026, roughly 60–65% of privately rented homes in England and Wales already meet EPC band C. That leaves around 35–40% of rental properties, or approximately 1.3 to 1.5 million homes, that still need upgrades to reach the required standard (English Housing Survey 2025–26, MHCLG/DESNZ; Energy Performance of Buildings Data, DESNZ, 2026).
The properties most likely to fall short are older homes with solid walls, single glazing, or uninsulated lofts. If your property is band D or E, you are in the group that needs action. The good news is that many of these homes can reach band C with fabric-first improvements costing well under £5,000.
Quick numbers typical upgrade costs and savings per measure
| Measure | Typical cost range (GBP) | Typical annual energy saving (GBP) | Payback period (years) |
|---|---|---|---|
| Cavity wall insulation | 500–1,500 | 200–400 | 2–6 |
| Loft insulation (top-up) | 300–600 | 100–200 | 3–5 |
| Solid wall insulation (internal) | 4,000–8,000 | 300–600 | 8–15 |
| Double glazing (full house) | 4,000–8,000 | 200–400 | 10–15 |
| LED lighting (full house) | 100–300 | 50–100 | 1–3 |
| Air source heat pump | 7,000–14,000 | 300–700 | 10–20 |

The cheapest route to EPC band C is often fabric-first insulation
Fabric-first upgrades—loft insulation, cavity wall insulation, and draught-proofing—are typically the most cost-effective way to lift a property from band D or E to band C. These measures often cost less than £2,000 combined and can deliver the biggest energy performance gains for the lowest outlay (Energy Saving Trust “Fabric first” guidance, 2026; EST “Cost-effective EPC improvements”, 2026).
Replacing a gas boiler with a heat pump is rarely the cheapest route to band C unless the property already has good insulation. If your property has solid walls or is in a conservation area, you may need internal or external wall insulation, which costs more but can still be a sound investment over the long term. Start with the EPC recommendation report to identify the most impactful measures for your specific property.
How to check if your property already qualifies and what to do if it doesn’t
First, obtain a current EPC certificate, which is valid for ten years. You can check your property’s rating on the Ofgem EPC register (GOV.UK EPC register, 2026). If the rating is band C or above, you are compliant for new tenancies until the certificate expires. If it is band D or lower, review the EPC recommendation report that comes with the certificate. This report lists the most cost-effective improvements in order of priority (GOV.UK EPC guidance, 2026).
If the property is band F or G, you need to act urgently. These properties are already subject to a minimum standard of EPC E, but the 2030 target means you must plan for a significant upgrade. A qualified energy assessor can provide a more detailed assessment if the EPC recommendations are unclear.

Eligibility for grants and funding to help reach EPC band C
Several government schemes can help cover the cost of upgrades. The Great British Insulation Scheme (GBIS) covers cavity wall and loft insulation for eligible low-income households, though landlords may need to check if their tenants qualify (GOV.UK GBIS, DESNZ, 2026). The Boiler Upgrade Scheme (BUS) provides £7,500 off the cost of an air source heat pump, and unlike GBIS, there is no income cap, so landlords can apply directly (GOV.UK BUS, DESNZ, 2026).
Local Authority Delivery (LAD) schemes may offer additional support in specific council areas, but funding varies by region and is often targeted at low-income households (Ofgem LAD scheme, 2026). Check your local council’s website for current offers. None of these grants cover the full cost of major works, but they can reduce the financial burden significantly.
The MCS certification requirement and how to verify installer credentials
If you plan to install a heat pump, the work must be carried out by an MCS-certified installer to qualify for the Boiler Upgrade Scheme grant. MCS (Microgeneration Certification Scheme) is the industry standard for renewable heating and solar installations (MCS “Find an installer”, 2026). For insulation work, installers should be registered with TrustMark or a competent person scheme such as CERT or FENSA for windows (TrustMark “Find a tradesperson”, 2026; GOV.UK competent person schemes, 2026).
Always verify credentials before paying a deposit. Uncertified work may not comply with building regulations and could invalidate your grant eligibility or insurance. Keep copies of all certificates and installer documentation for your records.
