What Happens After an EPC Assessment? A London Property Owner’s Next Steps

Booking an Energy Performance Certificate is only one part of preparing a property for sale, letting or future improvements. Once the EPC assessment has been completed, many property owners are left wondering what they should do next.

Should you immediately start marketing the property? Do you need to make the recommended improvements? How long does the certificate remain valid? And what should you do if the rating is lower than expected?

This guide explains the practical steps to take after an EPC assessment, whether you are a homeowner, landlord, seller or property professional in London.

1. Check That Your EPC Has Been Registered

After the assessment, your energy assessor submits the relevant information through their accreditation scheme so that the EPC can be lodged on the official register.

Once you receive your certificate, check the property details carefully. Make sure the address and property information are correct and that the certificate corresponds to the property that was assessed.

You can check an existing Energy Performance Certificate on GOV.UK by searching using details such as the postcode, street name and town or certificate number.

An EPC is generally valid for 10 years unless a newer EPC is produced for the same property.

2. Look Beyond the EPC Rating

The large A to G rating is usually the first thing property owners notice, but it is not the only useful information on an EPC.

Your certificate can also provide recommendations relating to the property’s energy performance.

Depending on the property, recommendations may relate to:

  • Heating systems

  • Insulation

  • Windows and glazing

  • Lighting

  • Hot water

  • Renewable technologies

  • Heating controls

Rather than focusing only on the letter rating, read the recommendations report and consider which improvements are realistic for your property.

If your rating is lower than expected, our guide to improving your EPC rating explains some of the improvements property owners can consider.

3. Don’t Assume That Every Recommendation Must Be Completed

An EPC recommendation is not automatically a requirement to carry out the work.

The suitability of an improvement depends on the building, its construction, cost, condition and your plans for the property.

For example, a recommendation involving insulation may be practical for one property but unsuitable for another because of its construction.

Government EPC guidance explains that EPCs include recommendations for improving energy efficiency.

This is particularly important for older London properties where construction methods and conservation considerations can vary significantly.

4. Decide Whether You Are Selling or Renting

Your next steps will depend heavily on what you intend to do with the property.

Selling a Property

If you are selling, check that you have the required EPC information ready before progressing with your property marketing.

In England, an EPC must generally be commissioned before a property is marketed for sale where there is no valid EPC already in place.

You can read the official GOV.UK guidance on Energy Performance Certificates when selling a home for the latest requirements.

Renting a Property

Landlords should check the EPC before advertising a rental property.

If you are preparing a rental property, our guide to EPCs for renting a property in London explains the main considerations for landlords.

It is also worth checking the latest government requirements because rental-property rules can change.

5. Check Whether Your EPC Is Still Valid

You do not normally need to order a new EPC simply because the property is being sold or rented again.

A valid EPC is generally usable for 10 years unless it has been replaced by a newer certificate.

Before paying for another assessment, check your property’s existing EPC on GOV.UK.

This simple step can prevent property owners from unnecessarily ordering a new certificate when a valid EPC already exists.

If you do need a new assessment, our London EPC cost guide explains some of the factors that can affect the price.

6. What If Your EPC Rating Is Lower Than Expected?

Receiving a lower rating than expected does not automatically mean you need to carry out expensive building work.

Start by looking at the recommendations on the certificate.

Some properties may benefit from relatively straightforward improvements such as:

  • Energy-efficient lighting

  • Draught reduction

  • Additional insulation

  • Improved heating controls

  • Hot water insulation

Other properties may require more substantial improvements.

The correct approach is to understand what is affecting your particular property rather than assuming that the same improvement will work equally well for every building.

If you are a landlord, it is particularly important to distinguish between current requirements and proposed or future policy changes.

Read our EPC C rating and 2030 guide for London landlords for more information.

7. Consider the Timing of Any Improvements

If you are planning energy-efficiency work, consider when the improvements need to be completed.

For example, a homeowner preparing to sell may want to assess whether an improvement is worthwhile before marketing.

A landlord may instead be planning upgrades between tenancies or as part of a longer-term property investment strategy.

There is no universal improvement plan for every London property.

Before spending money, consider:

  • The existing EPC rating

  • The recommendation report

  • The property’s age and construction

  • The cost of the proposed work

  • Whether planning or other permissions may be relevant

  • Your intended use of the property

  • Whether you will need a new EPC after improvements

8. Remember That Improvements Do Not Automatically Change Your EPC

One important point is often overlooked.

If you improve your property after an EPC assessment, your existing certificate does not automatically update.

For example, if you replace the heating system or improve insulation after your EPC was issued, the old certificate will continue to show the rating recorded at the time of assessment.

If you need the improvements reflected on an official EPC, a new assessment will normally be required.

This is particularly relevant if you want to demonstrate an improved rating before renting or selling.

The official government guidance explains that EPC data is lodged on the register and that the most recent EPC for a building is the valid one where multiple EPCs exist.

9. Prepare the Rest of Your Property Listing

An EPC is only one part of preparing a property for the market.

If you are selling or renting, you may also need:

  • Professional property photography

  • A measured floor plan

  • Accurate property information

  • Room measurements

  • Marketing descriptions

  • Relevant property documentation

For landlords and sellers preparing a property in Croydon, our property marketing guide for Croydon explains how EPCs, professional photography and floor plans can be arranged together.

Combining services can be particularly useful when you are working to a tight marketing deadline.

10. What If You Need the EPC Quickly?

Sometimes an EPC assessment happens later than planned.

A sale may be progressing quickly, a property may be becoming vacant, or a landlord may discover that an existing EPC has expired.

In these circumstances, arranging an assessment promptly can help prevent unnecessary delays.

Our same-day EPC guide for London explains the fast-track process and what property owners should expect from an urgent assessment.

Availability depends on the property location, assessor availability and the circumstances of the assessment.

You can also use the official GOV.UK service to arrange a new energy certificate and find an accredited assessor.

11. Keep Your EPC With Your Property Records

Once you receive the certificate, keep a digital copy with your other property documents.

For landlords and property managers, this can make future property administration much easier.

A useful property record can include:

  • Current EPC

  • Previous EPCs

  • Boiler information

  • Insulation information

  • Window and glazing information

  • Receipts for energy-efficiency improvements

  • Relevant installation certificates

  • Property floor plans

  • Other important property documents

Keeping this information together can help when the property is sold, rented or reassessed in the future.

GOV.UK also recommends getting the necessary property paperwork together when preparing a home for sale.

12. Use the EPC as a Planning Tool

An EPC is more useful when treated as a starting point rather than simply a compliance document.

The certificate can help you understand where the property currently stands and identify areas that may be worth investigating.

For example, a landlord with several properties could use EPC records to identify which properties require attention first.

A homeowner planning to remain in the property for several years may use the recommendations to create a longer-term improvement plan.

The important thing is to match the recommendations to your property’s circumstances rather than making decisions based only on the headline rating.

EPC Aftercare Checklist

Once your assessment is complete, use this checklist:

  • Check that the EPC details are correct

  • Confirm that the certificate has been lodged

  • Review your current A to G rating

  • Read the recommendations report

  • Check whether the EPC is still valid

  • Decide whether any improvements are worthwhile

  • Keep evidence of completed improvements

  • Arrange a new EPC if you need the updated work reflected

  • Prepare photography and floor plans if marketing the property

  • Check the latest government requirements before selling or renting

Frequently Asked Questions

Does an EPC automatically update after improvements?

No. Improvements made after an EPC assessment do not automatically change the existing certificate. A new assessment is normally needed if you want the improvements reflected on a new EPC.

How long is an EPC valid?

An EPC is generally valid for 10 years unless a newer EPC is produced for the property.

Do I have to complete every recommendation on my EPC?

Not necessarily. EPC recommendations identify potential energy-efficiency improvements. Whether a particular improvement is appropriate depends on the property and your circumstances.

Can I sell my property after receiving an EPC?

An EPC is one of the requirements associated with selling a property in England. Where there is no valid EPC, one generally needs to be commissioned before the property is marketed.

What should a landlord do after receiving an EPC?

A landlord should check the rating, review the recommendations, confirm the certificate is valid and consider whether any improvements are appropriate before marketing or continuing to let the property.

What if I need another EPC urgently?

If your previous EPC has expired or you need a certificate quickly, you can enquire about a fast EPC assessment. Availability depends on location and assessor schedules.

Final Thoughts

Receiving your EPC should not be the end of the process.

The certificate gives you useful information about your property’s energy performance, but the most appropriate next step depends on whether you are selling, letting, improving or simply keeping your property records up to date.

Start by checking the certificate, reviewing the recommendations and confirming its validity. If improvements are appropriate, plan them around your property’s condition and your long-term objectives.
