EPC Rating D Explained
Average energy efficiency (55-68)
An EPC rating of D is the national average for UK properties. D-rated homes have typical energy costs of around £1,800 per year. About 28% of UK properties have a D rating, making it one of the most common ratings alongside C. While acceptable, D-rated properties could benefit from improvements to reduce energy bills and carbon emissions.
What Does an EPC Rating D Mean?
A D-rated property has average energy efficiency for the UK. These homes have some insulation and energy-saving features but also have room for improvement. Energy bills are typical for the UK housing stock.
D is the benchmark average rating. Properties rated D are neither particularly efficient nor inefficient by current UK standards, but may face pressure to improve as energy efficiency expectations increase.
Typical Properties with Rating D
Standard gas boiler (may be older model)
Partial or full cavity wall insulation
Some loft insulation (often less than 200mm)
Double glazing (may be older units)
Some areas lacking insulation
Mix of efficient and inefficient lighting
Energy Costs for D-Rated Properties
Properties with an EPC rating of D typically cost around £1800 per year to heat and power, based on current UK energy prices.
How to Improve from Rating D
D-rated properties have good potential for improvement. These cost-effective upgrades can help reach a C rating:
Top up loft insulation
Increase to 270mm+ for significant heat savings
Cavity wall insulation
If not already done, this provides major improvement
Upgrade boiler
Replace with modern A-rated condensing boiler
Draught-proofing
Seal gaps around doors, windows and floors
Can I Rent a Property with Rating D?
Currently compliant for rental
May need improvement to C by 2030 under proposed regulations.
Under the Minimum Energy Efficiency Standards (MEES), landlords in England and Wales cannot grant new tenancies for properties rated F or G unless they have a valid exemption. The government has proposed increasing this minimum to C by 2030.
Frequently Asked Questions
Is D a bad EPC rating?
D is the national average, so it's neither good nor bad. However, it means higher energy bills than more efficient homes and may require improvement for rental properties in future.
How much does it cost to improve from D to C?
Improving from D to C typically costs £1,000-£5,000 depending on what measures are needed. Simple upgrades like loft insulation can make a significant difference.
Can I rent out a D-rated property?
Yes, D-rated properties currently meet MEES requirements. However, proposed regulations may require improvement to C by 2030 for new tenancies.
