Can You Rent an EPC D Property in 2026?
Yes, you can legally rent an EPC D property in the UK in 2026. The current Minimum Energy Efficiency Standard (MEES) requires a minimum EPC rating of E for all private rented properties. A D-rated property is compliant today. However, from 1 October 2030, the minimum rises to EPC C for all tenancies, both new and existing. Landlords with D-rated properties have a four-year window to upgrade or face fines of up to £30,000 per property.
Key Facts
- Current minimum (2026): EPC E. D-rated properties are legally compliant right now
- Future minimum (from 1 October 2030): EPC C for all tenancies, new and existing
- No split deadline: The government reversed the earlier proposal for an earlier new-tenancy deadline. One date applies to all tenancies: 1 October 2030
- Cost cap: £10,000 maximum spend per property to reach EPC C. Spending from 1 October 2025 counts
- Low-value cap: 10% of property value if valued under £100,000
- Fine for non-compliance: Up to £30,000 per property (up from £5,000)
- 52% of PRS below C: Over half of private rented stock is currently rated D or below (EPCGuide analysis of 29.2M EPC records)
- Typical D-to-C cost: £3,000-£8,000 depending on property type and measures needed
What are the current EPC rules for renting in 2026?
The current MEES regulations, in force since April 2020 for all tenancies, require a minimum EPC rating of E for any privately rented property in England and Wales. This means EPC ratings A through E are compliant, while F and G are not.
If your property is rated D, you are fully compliant with today's rules. You can let the property to new tenants, renew existing tenancies, and continue any current tenancy without any legal issue related to energy efficiency.
Per the government's guidance on GOV.UK (updated January 2026), the only immediate obligation for landlords of D-rated properties is to hold a valid EPC certificate. EPCs are valid for 10 years from the date of assessment.
When does the EPC C requirement start?
The EPC C minimum takes effect on 1 October 2030 for all privately rented properties in England and Wales. This applies to both new tenancies and existing tenancies on the same date.
The government's January 2026 consultation response confirmed this single deadline. An earlier proposal would have required EPC C for new tenancies from 2028, with existing tenancies following in 2030. That split deadline was dropped. Every private tenancy, regardless of when it started, must be in a property rated EPC C or above from 1 October 2030.
This is important for landlords with D-rated properties. There is no grace period, no phased introduction, and no distinction between a tenancy signed in 2025 and one signed in 2029. On 1 October 2030, every property must be at C or have a registered exemption.
For full details on the deadline, see our EPC C deadline guide.
What happens if you rent an EPC D property after 2030?
From 1 October 2030, letting a property rated below EPC C without a valid exemption is a criminal offence under MEES regulations. The penalties have been significantly increased:
For properties let on a non-qualifying EPC for less than 3 months: Fine of up to £10,000 or 10% of the rateable value (whichever is greater), capped at £30,000.
For properties let on a non-qualifying EPC for 3 months or more: Fine of up to £30,000 per property.
Publication penalty: The local authority can publish details of the breach, including the landlord's name and the penalty amount.
These penalties apply per property, not per landlord. A landlord with three D-rated properties still being let after October 2030 faces potential fines of up to £90,000.
Beyond fines, there are commercial consequences. Mortgage lenders are already tightening criteria for sub-C properties, and several major BTL lenders have indicated they will not offer new mortgages on properties below EPC C after 2030. This restricts your ability to refinance or sell to leveraged buyers.
For the full penalty framework, see our EPC fines and penalties guide.
How much does it cost to upgrade from EPC D to C?
The typical cost to upgrade a D-rated property to EPC C ranges from £3,000 to £8,000, depending on the property type, current rating within the D band (a high D is cheaper to upgrade than a low D), and which measures are needed.
According to MHCLG's impact assessment (2026), the average upgrade cost across all property types is £5,400. EPCGuide's analysis of 29.2M EPC records shows that D-rated properties typically need one to three of the following measures to reach C:
Low cost (under £1,000):
- Loft insulation top-up to 270mm: £300-£800
- LED lighting throughout: £100-£300
- Draught-proofing: £200-£400
- Hot water cylinder insulation: £100-£200
Medium cost (£1,000-£5,000):
- Cavity wall insulation: £1,500-£3,000
- Condensing boiler replacement: £2,500-£4,000
- Smart heating controls: £1,000-£1,500
Higher cost (£5,000+):
- Heat pump (minus BUS grant of £7,500): £500-£4,500 net
- Double glazing: £4,000-£8,000
- Solid wall insulation: £8,000-£15,000
Many D-to-C upgrades can be achieved with a combination of low-cost measures alone. A property rated D with 59 EPC points that needs 69 to reach C might only need loft insulation and LEDs to cross the threshold.
For a detailed breakdown, see our EPC D to C upgrade guide and cheapest ways to improve EPC rating.
Can you get an exemption for an EPC D property?
Yes. If you spend up to the £10,000 cost cap on qualifying improvements and the property still does not reach EPC C, you can register a cost cap exemption. The exemption is valid for 10 years and allows you to continue letting the property at whatever rating it reaches after the qualifying spend.
The cost cap was confirmed at £10,000 per property in the government's January 2026 response. Spending from 1 October 2025 onwards counts toward the cap. For properties valued under £100,000, the cap reduces to 10% of the property value.
Other exemption routes include:
Consent exemption: If a third party whose consent is needed (such as a freeholder or planning authority) refuses permission for the improvements.
Devaluation exemption: If a surveyor confirms the improvements would reduce the property's value by more than 5%.
Wall insulation exemption: If an independent surveyor advises that cavity, external, or internal wall insulation would damage the property.
All exemptions must be registered on the PRS Exemptions Register before letting or continuing to let the property. An unregistered exemption offers no protection.
For a step-by-step guide to exemptions, see our exemption register guide and £10,000 cost cap guide.
Should you upgrade now or wait until closer to 2030?
Upgrading sooner is almost always the better financial decision, for three reasons.
First, the cost cap clock is already ticking. Qualifying expenditure from 1 October 2025 counts toward the £10,000 cap. Money you spend now on improvements counts. Money you spent before October 2025 does not. There is no advantage to waiting.
Second, contractor availability will tighten. With 52% of PRS properties below EPC C, demand for insulation installers, heat pump engineers, and EPC assessors will spike as the deadline approaches. EPCGuide's analysis projects that the 2028-2029 period will see significant price inflation and longer wait times for energy efficiency works.
Third, you capture the financial benefit immediately. A C-rated property commands 5-10% higher rent, attracts tenants faster, and qualifies for green mortgage discounts of 0.1-0.3%. Every month your property sits at D rather than C, you lose that additional income. On a £1,000/month property, that is £50-£100 per month in foregone rent.
The break-even is typically under four years. A £5,000 upgrade that generates £1,350 per year in combined rent premium, mortgage savings, and void reduction pays for itself in 3.7 years. After that, it is pure profit.
For more on the financial case, see our guide on EPC rating and property value.
What about the new EPC methodology coming in 2029?
The government has confirmed that the EPC assessment methodology will change from 1 October 2029. The current Standard Assessment Procedure (SAP/RdSAP) will be replaced by the Home Energy Model (HEM), which measures how properties retain heat rather than how much energy they use.
For landlords with D-rated properties, the key detail is the transitional provision: if your property receives an EPC rated C or above before 1 October 2029 under the current methodology, that certificate remains valid and you are deemed compliant until it expires (up to 10 years).
This creates a strong incentive to get your EPC reassessed before October 2029. A C rating under the current system locks in your compliance status. If you wait until after October 2029, your property will be assessed under the new HEM methodology, and the goalposts may move.
For more on the new system, see our new EPC metrics 2029 guide.
What should landlords with EPC D properties do now?
Step 1: Check your current EPC. Find it on the EPC register. Note the rating, the score (out of 100), and the recommended improvements listed on the certificate.
Step 2: Get quotes for the recommended measures. Focus on the cheapest improvements first, as these often deliver the biggest EPC point gains per pound spent.
Step 3: Complete low-cost improvements immediately. Loft insulation, LEDs, and draught-proofing can often shift a high D (58-68 points) into C territory (69+) for under £1,000.
Step 4: Get a new EPC after the works. If you reach C, you are done. The certificate is valid for 10 years, locking in your compliance well beyond 2030.
Step 5: If still below C after low-cost measures, plan medium-cost works (boiler, cavity wall insulation) for 2027-2028. Apply for the Boiler Upgrade Scheme if considering a heat pump.

Frequently Asked Questions
Is it legal to rent an EPC D property in 2026?
Yes. The current MEES minimum is EPC E, so a D-rated property is fully compliant. You can let to new tenants, renew tenancies, and continue existing tenancies without any issue. This changes on 1 October 2030 when the minimum rises to EPC C.
When do I need to upgrade my EPC D property?
By 1 October 2030. The deadline applies to all tenancies, both new and existing, on the same date. There is no earlier deadline for new tenancies. Spending from 1 October 2025 counts toward the £10,000 cost cap, so there is no financial reason to delay.
How many EPC points do I need to go from D to C?
EPC D covers scores of 39-54 on the old scale, while C starts at 55. Under the current methodology, D is 39-54 and C is 55-68. In practice, a property at the top of band D (score 52-54) may need only loft insulation and LEDs to cross into C. A property at the bottom of band D (score 39-42) will likely need a boiler replacement or insulation.
Can I sell an EPC D property instead of upgrading?
Yes, but be aware that D-rated properties are already selling at a discount of 3-5% compared to C-rated equivalents (per Savills 2025 analysis). As 2030 approaches, this discount will widen. Buyers will deduct the upgrade cost plus a risk margin from their offer. If you plan to sell, doing so sooner captures a smaller discount than waiting.
What if my EPC D property is in Scotland?
Scotland has different rules. The Energy Efficiency Standard for Social Housing (EESSH) applies to social housing, while private rented sector requirements are set separately by the Scottish Government. The 2030 EPC C deadline applies to England and Wales only. For Scottish rules, see our Scottish landlord EPC guide.
Does the EPC C deadline apply to Wales?
Yes. The January 2026 regulations apply to both England and Wales. Welsh landlords face the same 1 October 2030 deadline, the same £10,000 cost cap, and the same penalties as English landlords. For Welsh-specific guidance, see our Wales EPC guide.
Can I get a grant to upgrade my EPC D property?
Yes. The Boiler Upgrade Scheme provides up to £7,500 toward heat pump installation with no income requirement. The Warm Homes Local Grant covers insulation and heating for properties with low-income tenants. ECO4 runs until December 2026. These schemes can significantly reduce or eliminate your out-of-pocket cost.
Will my mortgage be affected by an EPC D rating after 2030?
Likely yes. Several major BTL lenders have indicated they will not offer new mortgages on sub-C properties after 2030. If you need to refinance a D-rated property, your options will be limited to lenders who accept non-compliant properties, likely at higher interest rates.
