How Long Does an EPC Take

When selling or letting a property in the UK, one of the legal requirements is to obtain an Energy Performance Certificate, often referred to as an EPC. This document gives potential buyers or tenants an idea of how energy efficient a home is and what improvements could make it cheaper to run. One of the most common questions homeowners and landlords ask is how long an EPC actually takes. The answer depends on several factors, including the size of the property, its layout, and how prepared the owner is for the assessor’s visit.

Understanding the EPC Process

An EPC is carried out by a qualified Domestic Energy Assessor. The assessor visits the property and collects data about its construction, insulation, heating systems, and overall energy use. They record details such as wall thickness, loft insulation depth, boiler efficiency, window glazing, and even the number of low energy light bulbs in the home. Once all this information has been collected, the data is entered into government-approved software that generates an efficiency rating from A to G.

Average Time for an EPC Survey

In most cases, an EPC assessment for a standard two or three-bedroom house takes between 30 minutes and one hour. Flats and smaller homes may be completed more quickly, while larger detached houses, properties with multiple extensions, or those with unusual construction features may take longer. If the property has outbuildings, annexes, or a non-standard layout, the survey can extend beyond an hour as the assessor needs to check each section thoroughly.

Factors That Affect the Duration

Several elements can influence how long the EPC takes. The first is the accessibility of key areas, such as lofts or boiler cupboards. If the assessor cannot reach these parts easily, time will be spent waiting or making alternative arrangements. The age and complexity of the property also make a difference. A modern home with standard construction is generally quicker to assess than an older house with a mix of improvements over time. The presence of renewable technologies, such as solar panels or heat pumps, can also add extra minutes to the survey, as the assessor must take detailed notes and record additional data.

What Happens During the Visit

The assessor will walk through each room, taking measurements, photographs, and notes. They will check the type of walls, roof, windows, and floors to establish how well the property retains heat. Heating systems are a major focus, so the assessor will look at the boiler, radiators, and thermostats. If you have energy-saving measures already installed, such as cavity wall insulation or double glazing, these will be noted to help improve the rating. Once all the information has been collected, the on-site visit ends, but the final EPC document is usually sent to you within two to three working days.

How to Make the EPC Quicker

Homeowners and landlords can help speed up the process by preparing in advance. Making sure that the assessor can easily access the loft, boiler, meters, and hot water tank will reduce delays. Having paperwork to hand, such as receipts for insulation or installation certificates for double glazing and heating systems, can also make the survey more efficient. The assessor may otherwise have to assume the property does not have certain features, which can affect the final rating.

When You Will Receive the Certificate

While the site visit may only take an hour or so, the EPC is not usually available immediately. The assessor will need time to input the data, generate the report, and lodge it on the national EPC register. Most certificates are delivered electronically within two to three days of the assessment. If you are working to a tight deadline, some assessors offer same-day or next-day services for an additional fee.

Why the Length of the Survey Matters

Although the assessment itself is relatively quick, the timing is important because an EPC is legally required before you market a property for sale or rent. If you leave arranging it too late, you could face delays in putting the property on the market. Since the certificate is valid for ten years, many owners choose to obtain one well before they plan to sell or let, giving them time to act on the recommendations and potentially raise the property’s rating.

Conclusion

An EPC does not take long to complete, with most assessments finished in under an hour, and the certificate issued within a few days. The exact length of time depends on the type and size of the property, as well as how prepared the owner is for the visit. By understanding what the assessor will be looking for and making the property accessible, you can ensure the process runs smoothly and without unnecessary delays. This simple preparation not only helps save time but also ensures you receive the most accurate energy rating possible.
