If you're selling, renting, or even just looking to improve your home's energy efficiency, you’ve likely come across the term Domestic EPC (Energy Performance Certificate). But what exactly is it, why is it important, and how can you get one?
In this comprehensive guide, we’ll cover everything you need to know about Domestic EPCs, including:
What a Domestic EPC is
Why it’s important
How it’s calculated
The costs involved
How to improve your EPC rating
Legal requirements
By the end, you’ll have a clear understanding of how an EPC affects your property and what steps you can take to make your home more energy-efficient.
What is a Domestic EPC?
An Energy Performance Certificate (EPC) is a document that assesses the energy efficiency of a property on a scale from A (most efficient) to G (least efficient). It provides:
An energy efficiency rating (current and potential)
Estimated energy costs for heating, lighting, and hot water
Recommendations for improving efficiency
The property’s carbon dioxide emissions
EPCs are required by law when selling or renting a property in the UK and are valid for 10 years.
Why is a Domestic EPC Important?
1. Legal Requirement
Since 2007, UK law mandates that all homes being sold or rented must have a valid EPC. Failing to provide one can result in fines of up to £5,000.
2. Helps Buyers & Tenants Make Informed Decisions
An EPC gives potential buyers or renters insight into:
Expected energy bills
The property’s environmental impact
Potential cost-saving improvements
Homes with higher ratings (A or B) are often more attractive to buyers and renters.
3. Identifies Energy-Saving Opportunities
The EPC includes recommendations for upgrades like:
✅ Better insulation
✅ More efficient heating systems
✅ Double glazing
✅ Renewable energy solutions (e.g., solar panels)
These improvements can lower bills and increase property value.
4. Supports Government Energy Efficiency Goals
The UK aims for net-zero carbon emissions by 2050, and EPCs help track and improve home energy efficiency nationwide.
How is an EPC Calculated?
A qualified domestic energy assessor evaluates key factors, including:
Insulation (loft, walls, floors)
Heating system (boiler type, controls)
Windows (single/double glazing)
Lighting (LED vs. halogen bulbs)
Renewable energy sources (solar panels, heat pumps)
The assessor inputs this data into software that generates the EPC rating.
EPC Rating Scale
| Rating | Efficiency Level |
|---|---|
| A (92-100) | Most efficient |
| B (81-91) | Very efficient |
| C (69-80) | Good |
| D (55-68) | Average |
| E (39-54) | Below average |
| F (21-38) | Poor |
| G (1-20) | Least efficient |
Most UK homes fall between D and E. Since 2018, rental properties must have at least an E rating (with some exemptions).
How Much Does a Domestic EPC Cost?
The cost varies depending on:
Property size
Location
Assessor fees
On average, a Domestic EPC costs £60–£120. While it’s possible to find cheaper options, choosing an accredited assessor ensures accuracy.
How to Improve Your EPC Rating
If your home has a low EPC rating, consider these upgrades:
1. Improve Insulation
Loft insulation (can save up to £315/year)
Cavity wall insulation (reduces heat loss significantly)
Floor insulation (especially in older homes)
2. Upgrade Heating Systems
Install a condensing boiler (more efficient)
Use smart thermostats (better temperature control)
Consider heat pumps (for eco-friendly heating)
3. Switch to LED Lighting
Replacing halogen bulbs with LEDs is a quick, low-cost improvement.
4. Install Double Glazing
Single-glazed windows lose heat quickly—double or triple glazing can boost efficiency.
5. Add Renewable Energy Sources
Solar panels (reduce electricity bills)
Solar water heating (cuts hot water costs)
Even small changes can move your rating from E to C, making your home cheaper to run and more marketable.
Legal Requirements for Domestic EPCs
For Sellers & Landlords
You must provide an EPC when selling or renting.
The EPC must be less than 10 years old.
Rental properties must meet minimum EPC E (unless exempt).
Future Changes (2025 & Beyond)
The UK government plans to raise minimum EPC standards:
2025: New rentals may require EPC C.
2030: All homes may need at least EPC C.
Staying ahead of these changes can prevent future compliance issues.
How to Get a Domestic EPC
Find an Accredited Assessor – Use the EPC Register.
Book an Assessment – The assessor will inspect your property (takes ~1 hour).
Receive Your Certificate – You’ll get the EPC within 24–48 hours.
Final Thoughts
A Domestic EPC is more than just a legal requirement—it’s a valuable tool for saving money, improving comfort, and reducing environmental impact. Whether you're selling, renting, or simply looking to cut energy bills, understanding your EPC can help you make smarter decisions.
If your rating is low, consider making energy-efficient upgrades to increase your home’s value and appeal. And if you need an EPC, always use a qualified assessor for accurate results.
