Chelmsford’s property market saw high transaction volumes throughout the mid-2010s, particularly across commuter-friendly areas such as Springfield, Great Baddow, Galleywood and Writtle. As a result, a large number of Energy Performance Certificates (EPCs) were issued around 2015–2016 — many of which are now expiring.
Why EPC Expiry Is Becoming an Issue in Chelmsford
EPCs are valid for 10 years. This means any certificate issued in 2016 will expire at some point in 2026 and can no longer be used for selling or letting a property.
In Chelmsford, EPC expiry is often discovered late because:
- Properties have remained in the same ownership for long periods
- Homes are re-marketed quickly in strong demand areas
- Owners assume an old EPC can still be reused
Once an EPC has expired, marketing must pause until a new assessment is completed.
How Expired EPCs Delay Sales and Lettings
An expired EPC can cause issues at several stages of a transaction:
- Estate agents cannot legally list the property
- Buyers may raise concerns during conveyancing
- Lenders may request updated documentation
- Landlords may be unable to re-let a property
Nationally, EPC-related delays are one of the most common compliance issues affecting property transactions. This is explored further in our guide on common EPC mistakes that delay sales and rentals.
Do You Need a New EPC If Yours Has Expired?
Yes. Once an EPC has expired, it cannot be extended or updated. A completely new assessment must be carried out before the property can be marketed or legally let.
You may also benefit from a new EPC even if yours is still valid if you have:
- Installed a new boiler
- Added insulation
- Upgraded windows or doors
- Extended or altered the property
How Long Does a New EPC Take?
A standard EPC assessment typically takes between 30 and 60 minutes, depending on the size and layout of the property.
The assessor will record:
- Heating systems and controls
- Insulation levels
- Wall and roof construction
- Glazing type
- Any extensions or alterations
In most cases, the EPC is lodged and available digitally on the same day.
