Domestic & Commercial EPC Assessments

An expired EPC can hold up a sale, delay a new tenancy, slow down a handover or leave you chasing paperwork at the last minute.

You do not need another job landing on your desk when you are already dealing with tenants, contractors, buyers, agents or completion dates.

AVT UK provides domestic and commercial Energy Performance Certificates for homeowners, landlords, property managers, developers and businesses.

You get a clear, professional assessment from a qualified EPC assessor, a straightforward certificate and practical advice on what the rating means for your property.

If your result raises bigger questions around heat loss, draughts, insulation, ventilation or condensation, we can help you look into those too.

An Energy Performance Certificate, usually shortened to an EPC, shows how energy efficient a property is.

Your EPC gives the building a rating from A to G, with A being the most energy efficient and G being the least. It gives you a clear picture of how the property is expected to perform, helping you understand where improvements could make a difference.

How To Find An Existing EPC Certificate Before You Book

Before arranging a new EPC assessment, it is worth checking whether the property already has a valid certificate.

You can use the official government Energy Performance Certificate register to find an EPC for a home, business premises or public building in England, Wales or Northern Ireland.

You can search using:

• The property postcode.
• The street name and town.
• The EPC certificate number, if you have it.

Once you find the certificate, you can view the current EPC rating, check when it was issued and download a copy free of charge.

If the property does not appear on the register, the certificate has expired or you need the rating to reflect recent improvement work, you may need to arrange a new assessment.

Our guide on how to find your EPC certificate and check whether you need a new one takes you through the process step by step.

How To Find The Right EPC Assessor

When you search for an EPC assessor near you, do not choose someone based on availability or price alone.

A valid EPC must be produced and lodged by an accredited energy assessor. You also need someone who is qualified to assess the type of property you are dealing with.

Before you book, check that the assessor:

• Is accredited to produce and lodge Energy Performance Certificates.
• Provides the correct domestic or commercial EPC assessment.
• Has experience with your type of property.
• Explains what information is needed before the appointment.
• Provides clear pricing based on the size and complexity of the building.
• Can explain what the final rating and recommendations mean.
• Offers practical support if the EPC highlights wider performance problems.

You can use the official GOV.UK assessor service to check that an energy assessor belongs to an approved accreditation scheme.

AVT UK provides both domestic and commercial EPC assessments, so you do not need to work out which provider to contact before speaking to us.

Tell us about the property and what you need the certificate for. We will explain the right assessment, what the visit will involve and what you need to have ready.

Commercial EPC Assessments For Business Premises

A commercial EPC is needed for many business premises when they are sold, let or completed.

If you own, manage or lease commercial property, missing paperwork can easily delay a deal. You may be waiting on solicitors, dealing with a tenant who wants to move in or preparing a building for handover. The last thing you need is an EPC becoming the reason everything stalls.

AVT UK provides commercial EPC assessments for a wide range of premises, including:

• Offices
• Retail units
• Warehouses
• Industrial buildings
• Hospitality venues
• Mixed-use properties
• Managed commercial portfolios

Your commercial EPC gives you an energy rating for the building and shows areas where its energy performance could be improved.

It can help you:

• Keep a sale or lease moving
• Meet your property compliance responsibilities
• Understand the building’s current energy performance
• Plan sensible energy-saving improvements
• Make the property more attractive to prospective tenants or buyers

For commercial landlords, a poor EPC rating can create a bigger problem than a certificate deadline. If a property falls below the required minimum standard and no exemption applies, it may not be possible to continue letting it.

AVT can help you get the commercial EPC you need, then look beyond the rating if there are wider building performance issues to resolve.

More Than An EPC Certificate: Building Performance Support From AVT

An EPC gives you a rating and recommended improvements. It does not diagnose the exact cause of a cold room, persistent draught, condensation issue or disappointing energy performance.

You may have a low EPC rating and still be unsure what is actually holding the building back.

That is where AVT stands apart from a certificate-only provider.

We specialise in building performance testing, so we can help you investigate the issues behind the rating. Depending on what the property needs, this may include:

• Air tightness testing to assess uncontrolled air leakage
• Thermal heat loss surveys using Heat3D to show where heat is escaping through the building fabric
• Ventilation testing to check air is moving through the property properly
• Switchee smart monitoring for ongoing data on temperature, humidity, heat loss and damp or mould risk

This means you are not left with an EPC certificate and a vague list of possible improvements.

You have access to a team that can help you understand how the building is performing in real life, identify what needs attention and make better decisions about your next step.
