EPC band D covers SAP scores from 55 to 68. It is legal to let a D-rated property today under the current Minimum Energy Efficiency Standards (MEES) Regulations, which set band E as the floor. However, the government has proposed raising that minimum to band C from 1 October 2030. If that proposal passes into law, every D-rated rental property in England and Wales will need to be upgraded before that date or face fines of up to £30,000 per property.
EPCGuide's analysis of a 75,000-certificate sample across 15 local authorities found that 29.9% of private rental properties are currently rated band D, making it the second most common band in the sector.
What Is an EPC D Rating?
An EPC D rating means the property scores between 55 and 68 on the Standard Assessment Procedure (SAP) scale. SAP runs from 1 (least efficient) to 100 (most efficient). Band D sits in the middle of the scale: below C, B, and A, but above E, F, and G.
| EPC Band | SAP Score | Landlord Status (England and Wales, 2026) |
|---|---|---|
| A | 92-100 | Compliant |
| B | 81-91 | Compliant |
| C | 69-80 | Compliant (proposed 2030 target) |
| D | 55-68 | Legal to let, upgrade proposed by 2030 |
| E | 39-54 | Legal minimum (barely compliant) |
| F | 21-38 | Illegal to let without registered exemption |
| G | 1-20 | Illegal to let without registered exemption |
A typical D-rated rental property has adequate but not efficient energy features: often a gas boiler without optimal controls, partial loft insulation, some draught-proofing, but no cavity or solid wall insulation, and possibly older windows. The property works, but it costs more to heat than a C-rated equivalent.
Can I Rent Out a Band D Property?
Yes. Under the MEES Regulations (SI 2015/962), the current legal minimum for private rented properties in England and Wales is band E. Band D sits above that threshold. You can let a D-rated property without an exemption, without registering anything, and without any immediate legal obligation to upgrade.
MEES applies to England and Wales only. Scotland operates a separate framework: Scottish landlords currently need a minimum of band D, with band C proposed by the end of 2028. The Scottish EPC landlord guide covers that framework in full.
What Do D-Rated Energy Bills Look Like?
Your EPC certificate includes an "Estimated Energy Cost" section showing your property's annual energy spend under standard occupancy assumptions. This figure uses a standardised calculation based on your specific property's construction, heating system, and insulation, so it is more accurate than any generic average.
Band D properties cost more to run than equivalent C-rated ones. The gap depends on what measure is missing: a house sitting at SAP 68 (top of band D, one point from C) costs little more than a C-rated equivalent. A house at SAP 55 (bottom of D, bordering on E) spends considerably more.
The "Estimated Energy Cost" on your EPC is the best starting point. If you do not have the certificate to hand, find your EPC certificate on the national register using your postcode.
What Does Band D Mean for the 2030 Proposed Standard?
The government's 21 January 2026 consultation response proposed raising the minimum EPC band for private rented properties to C from 1 October 2030. If that proposal passes into law, band D will no longer be compliant for new or existing tenancies from that date.
These are the proposed rules, not current law. The government must pass an Act of Parliament and then lay a Statutory Instrument amending the 2015 Regulations. Neither has happened. The earliest that instrument is targeted is 2027. The EPC C 2030 deadline guide explains the legislative steps still needed.
If the proposal does become law, the financial stakes are significant. The proposed cost cap is £10,000 per property (proposed, not law): the maximum a landlord would need to spend to reach band C before claiming an exemption. The proposed penalty for non-compliance is up to £30,000 per property, compared to the current £5,000 maximum under MEES.
The 2030 date is a single deadline. The government dropped the earlier 2025/2028 split during the January 2026 consultation. Spend on qualifying improvements from 1 October 2025 onwards would count toward the proposed £10,000 cap.
How Far Is Band D from Band C?
The gap is smaller than many landlords assume. Band D runs from SAP 55 to 68. Band C starts at SAP 69. Depending on where a property sits within band D, the gap to C is somewhere between one and fourteen SAP points.
A property at SAP 67 needs just two points to reach C. A property at SAP 55 needs fourteen. The SAP score and the recommended measures are both printed on your EPC certificate, so this calculation takes seconds to check.
The EPC D to C upgrade guide sets out the cheapest improvement sequence, typical SAP point gains per measure, and 2026 costs in detail. For most D-rated properties, loft insulation, heating controls, and draught-proofing are enough to cross the threshold without major works.
How Common Is Band D in the Private Rental Sector?
EPCGuide's analysis of a 75,000-certificate sample across 15 local authorities found that band D accounts for 29.9% of private rental properties, making it the second most common band after C (59.5% of the sample). Band E accounts for 3.5% of the sample.
Nationally, EPCGuide's analysis of 29.2 million EPC records shows that 55.4% of all certificates in England and Wales are currently below band C. The EPCGuide research hub includes an interactive map showing below-C rates for all 346 local authorities, from 24.9% in Tower Hamlets to 85% in the Isles of Scilly.
What Grants Are Available for D-Rated Landlords?
Two schemes are relevant for landlords with D-rated properties looking to upgrade to C before 2030.
ECO4 (closes 31 December 2026): Up to £14,000 per property is available under the Energy Company Obligation 4 scheme. Eligibility is tenant-gated: the tenant must meet an income or benefit threshold. If your tenant qualifies, ECO4 can fund insulation and heating upgrades at no cost to you. The scheme closes at the end of 2026; after that, the Warm Homes Plan takes over from 2027 with different eligibility rules. The ECO4 landlord guide covers the tenant eligibility criteria.
Boiler Upgrade Scheme (BUS): A £7,500 grant toward a heat pump. Landlords are eligible and there is no means-testing. The BUS funds the cost of switching from a gas or oil boiler to an air or ground source heat pump. The BUS landlord guide explains the application process.
Neither grant requires the property to be below C to apply. D-rated landlords can access both.

Frequently Asked Questions
Is an EPC D rating good enough to rent out a property? Yes, under current law. The MEES Regulations (SI 2015/962) set band E as the minimum for private rented properties in England and Wales. Band D is above that threshold and fully compliant. The proposed 2030 minimum of band C is not yet law.
What SAP score is an EPC D rating? Band D covers SAP scores from 55 to 68. Band C starts at 69. A property at SAP 68 needs just one point to move from D into C. Your current SAP score appears on the front page of your EPC certificate.
Does a D-rated property need to be upgraded before 2030? Only if the proposed 2030 standard passes into law. As of September 2026, no Act of Parliament or Statutory Instrument has been passed to raise the minimum from E to C. The government has proposed band C from 1 October 2030 but the legislation is still pending. Planning for the upgrade is sensible; you are not already in breach.
How much does it cost to upgrade from D to C? It depends on where in band D the property sits and what improvements are recommended on the certificate. For a property at SAP 65-68, often just loft insulation top-up or heating controls are enough. For a property at SAP 55-60, more substantial work may be needed. The EPC D to C upgrade guide covers realistic 2026 costs by improvement type.
Can I get grants for a D-rated property? Yes. ECO4 (closing 31 December 2026) provides up to £14,000 for tenant-eligible properties. The Boiler Upgrade Scheme provides £7,500 toward a heat pump and is available to landlords with no means-testing. The EPC grants for landlords guide covers both schemes in full.
What happens if my EPC expires while the property is tenanted? The EPC must be in place at the point of letting, not continuously during the tenancy. If the certificate expires mid-tenancy, you are not required to renew it immediately. You will need a valid certificate before re-letting. The EPC expiry mid-tenancy guide covers the rules in detail.
