Below are answers to some of the most common EPC questions.

If you’re arranging an Energy Performance Certificate (EPC) for the first time, you may have questions about the process, legal requirements and what happens during the assessment.

What Is An EPC?

An Energy Performance Certificate (EPC) measures the energy efficiency of a property.

The certificate provides:

• an energy efficiency rating from A to G
• estimated energy costs
• recommendations for improving efficiency
• information about the property’s construction and heating systems

When Is An EPC Required?

An EPC is normally required when:

• selling a property
• renting out a property
• marketing a property for sale
• marketing a property to let

In most cases, a valid EPC must be available before the property is advertised.

How Long Is An EPC Valid For?

A domestic EPC remains valid for:

10 years

from the date it is issued.

If your certificate is still valid, a new EPC may not be required unless you choose to obtain an updated assessment.

How Long Does An EPC Assessment Take?

Most EPC assessments take approximately:

30 to 60 minutes

depending on:

• property size
• property layout
• accessibility
• number of rooms

Larger properties may take slightly longer.

What Does The Assessor Need Access To?

To complete the assessment accurately, the assessor will usually need access to:

✔ All rooms
✔ All floors
✔ Loft space (where safely accessible)
✔ Boiler and heating systems
✔ Heating controls
✔ Windows and glazing
✔ Gas and electricity meters
✔ Extensions and converted areas

Providing full access helps ensure the most accurate EPC rating possible.

Do I Need To Be Present During The EPC?

In most cases, somebody will need to provide access to the property.

This could be:

• the owner
• tenant
• landlord
• estate agent
• letting agent
• authorised representative

Does The Property Need To Be Empty?

No.

The property can be:

• occupied
• furnished
• tenanted

The EPC assessment is non-invasive and does not involve any disruptive work.

What Happens During The EPC Assessment?

The Domestic Energy Assessor records information about:

• property construction
• insulation
• windows
• heating systems
• lighting
• hot water systems
• overall energy performance

This information is entered into approved government software which generates the EPC rating.

How Quickly Will I Receive My EPC?

In most cases, the completed EPC certificate is issued electronically within:

24 hours – of the assessment being completed.

Can A Low EPC Rating Be Improved?

Yes.

Many properties can improve their EPC rating through measures such as:

• increasing loft insulation
• improving wall insulation
• upgrading heating systems
• improving heating controls
• installing LED lighting
• reducing heat loss

The EPC report itself includes recommendations that may help improve efficiency.

Why Do Electric-Heated Properties Often Have Lower Ratings?

The EPC system considers estimated fuel costs when calculating ratings.

Properties relying entirely on electric heating can sometimes receive lower EPC ratings because electricity is generally assumed to be more expensive than mains gas.

This is particularly common in:

• flats
• apartments
• smaller rental properties

Does Double Glazing Improve An EPC Rating?

Double glazing can contribute positively towards energy efficiency and may improve EPC performance.

However, EPC ratings are based on the property as a whole, so insulation, heating systems and heating controls are often equally important.

Can Loft Insulation Improve An EPC Rating?

Yes.

Loft insulation is one of the most commonly recommended EPC improvements because it helps reduce heat loss through the roof.

Increasing insulation levels may improve both comfort and energy efficiency.

What Happens If Part Of The Property Cannot Be Accessed?

If certain areas cannot be inspected, the EPC software may require assumptions to be used.

In some situations, assumptions may affect the final rating.

Providing full access helps achieve the most accurate assessment.

Are EPC Recommendations Mandatory?

No.

The recommendations shown on an EPC are suggestions designed to improve energy efficiency.

Property owners can choose whether to carry out the recommended improvements.

However, landlords should ensure they comply with any applicable rental property regulations.

Can You Provide Advice After The EPC?

Yes.

Following the assessment, guidance can be provided regarding practical improvements that may help improve energy performance and efficiency.

For more detailed recommendations, an Energy Report may also be available.
