Non-Domestic EPCs Explained: A Guide for West Midlands Business and Commercial Property Owners

If you own or let a commercial property in the West Midlands, you need a Non-Domestic Energy Performance Certificate (EPC) before you can sell or rent it out — and if your building is currently rated F or G, you may already be in breach of the law. A Non-Domestic EPC rates your commercial building’s energy efficiency on a scale from A (most efficient) to G (least efficient), and under the current Minimum Energy Efficiency Standards (MEES), landlords cannot legally let a property rated below E.

That might sound straightforward, but the rules around who needs one, when, and what happens if you don’t have one are surprisingly easy to misunderstand. We regularly speak to West Midlands business owners and commercial landlords who have been caught off guard — either by a solicitor telling them they need a certificate to proceed with a sale, or by discovering they’re already in breach of MEES regulations that tightened in April 2023. With over 16 years of experience carrying out non-domestic EPC assessments across the region, we’ve put this guide together to give you clear, plain-English answers without the jargon.

Key Takeaways

A Non-Domestic EPC is legally required when selling, letting, or constructing a commercial property in England and Wales — and must be provided free of charge to prospective buyers or tenants at the earliest opportunity.
Since April 2023, MEES regulations apply to all continuing commercial lets, not just new tenancies — if your property is rated F or G and has a tenant in it, you are likely already in breach.
Fines for failing to provide an EPC when required range from £500 to £5,000, based on the property’s rateable value.
EPCs are valid for 10 years — you do not need a new one every time you re-let the property.
By 2030, the proposed minimum standard for commercially let buildings rises to a Band B rating — but currently only 8.4% of office buildings meet that threshold. Start planning now.

What Is a Non-Domestic EPC and How Is It Different from a Domestic One?

A Non-Domestic EPC is an official certificate that rates the energy efficiency of a commercial building — think offices, retail units, warehouses, light industrial units, and similar premises. Like a domestic EPC for a home, it uses a scale of A to G, with A being the most energy efficient and G the least.

The key difference is in the methodology and the qualifications required to produce one. Non-domestic assessments are considerably more complex than domestic ones. The assessor must be a qualified and accredited Non-Domestic Energy Assessor (NDEA), and the level of accreditation required varies depending on the complexity and type of building being assessed. The certificate itself shows the building’s current energy rating, its potential rating if recommended improvements are made, estimated CO₂ emissions, and a list of advisory recommendations — though as outlined in the GOV.UK guide to EPCs for non-dwellings, there is no legal requirement to carry out those recommendations. They are advisory only.

This is worth highlighting because we find it’s one of the most common points of confusion among commercial landlords — more on that in the myths section below.

When Do You Need a Non-Domestic EPC?

According to GOV.UK guidance on EPCs for business premises, you must have a Non-Domestic EPC in place if:

You are renting out or selling the premises — the EPC must be made available to any prospective buyer or tenant free of charge at the earliest opportunity
A new commercial building is completed following construction
Changes are made to the number of separate parts used for separate occupation, involving the provision or extension of fixed heating, air conditioning, or mechanical ventilation systems

The obligation applies regardless of the size of the property or the length of the tenancy, with some specific exemptions (see below).

If you’re unsure whether an existing valid EPC already exists for your property, the good news is that all Non-Domestic EPCs are lodged on a publicly searchable national register. You can search by address at the Find an Energy Certificate service on GOV.UK to check whether a certificate is still within its 10-year validity window.

Are There Any Exemptions?

Yes — but they’re narrower than many people assume. According to GOV.UK, you may not need a Non-Domestic EPC if the building is:

A listed or officially protected building, where meeting energy performance requirements would unacceptably alter its character or appearance
A temporary structure intended to be used for two years or less
Used exclusively as a place of worship or for other religious activities
An industrial site, workshop, or non-residential agricultural building that does not use much energy
A detached building with a total useful floor area of under 50 m²

A word of caution here, particularly for Black Country property owners: many people assume that any workshop or light industrial unit is automatically exempt. This is a misconception. The exemption applies to industrial sites and workshops that do not use much energy — if your unit has significant fixed heating, cooling, or ventilation systems, it is very likely to require an EPC. If you’re in any doubt about your position, it’s worth speaking to an accredited assessor before assuming you’re exempt.

What Does a Non-Domestic EPC Assessment Actually Involve?

We appreciate that for many business owners, the assessment process feels like a bit of a black box — especially if it’s the first time you’ve needed one. Here’s what actually happens during a visit.

The assessor will attend the property and carry out a full physical inspection, during which they will:

Record the construction details — the type and condition of the walls, roof, glazing, and any insulation present
Survey all building services — heating and cooling systems, ventilation, lighting, and hot water
Note how the building is used — whether it’s an office, retail unit, industrial premises, or a mixed-use space
Enter all the data into approved modelling software, such as iSBEM (for most standard commercial buildings) or Dynamic Simulation Modelling for larger, more complex properties
Generate the EPC and lodge it on the national Non-Domestic EPC register

For a small retail unit or single office, the visit itself typically takes an hour or two. Larger, multi-zone commercial buildings will naturally take longer. We always aim to turn certificates around quickly — many of our clients in Stourbridge, Dudley, Birmingham, and across the region tell us that speed and clear communication are exactly what they need, especially when a transaction is waiting on the certificate.

Assessors must be members of a government-approved accreditation scheme — bodies such as Stroma Certification, Elmhurst Energy, CIBSE Certification, and Quidos are among the main accreditors. Always check that whoever you use holds the appropriate level of accreditation for your building type.

How Much Does a Non-Domestic EPC Cost?

There is no fixed national fee — as GOV.UK confirms, the cost of an EPC depends on the building being assessed. That said, here are some indicative ranges based on market rates across the UK, which broadly apply to the West Midlands:

Small commercial unit (single office, small retail unit up to approximately 200 m²): typically £150–£350
Medium commercial property (larger office suite, mid-size retail, small industrial unit): typically £300–£600
Large or complex commercial buildings: can run to £500–£1,500 or more, depending on complexity, number of zones, and whether Dynamic Simulation Modelling is required

These are indicative figures and individual assessors may price differently. What we’d always encourage you to consider, though, is the cost of not having one — which brings us to perhaps the most important section in this guide.

What Are the Risks of Not Having a Non-Domestic EPC?

Failing to obtain or provide a Non-Domestic EPC carries real financial and legal consequences. Here’s what you’re actually risking:

Fines for non-compliance. If you fail to make an EPC available to a prospective buyer or tenant when required, you can be fined between £500 and £5,000, calculated on the rateable value of the property. That penalty applies per breach — so if you’ve marketed multiple units without a valid EPC, the exposure adds up.

You may be unable to let your property. Under current MEES regulations, commercial landlords in England and Wales cannot let a property with an EPC rating below E. This has been enforceable since April 2023 for all commercial lets — including existing leases where the tenant has been in place for years. As outlined by Higgs LLP’s MEES guidance for commercial landlords, if your property is sub-standard and there is a continuing tenancy, you are already in breach unless a valid exemption has been registered.

The 2030 deadline is approaching faster than you think. The government has proposed a trajectory that would require all commercially let buildings to achieve a minimum EPC Band B by 2030, with a Band C minimum for new tenancies from 2027. To put that into perspective, Avison Young’s analysis of EPC compliance across commercial sectors found that only 8.4% of office buildings currently achieve a B rating. The scale of improvement required across the sector is enormous — and the West Midlands, with its significant stock of older commercial and industrial buildings dating from the mid-to-late 20th century, is particularly exposed.

Tenant and buyer expectations are shifting. Increasingly, larger business tenants and investors are asking for energy performance evidence as part of their due diligence. A poor EPC rating can affect both your property’s rental value and its saleability.

A non-domestic EPC for a small commercial unit can cost as little as £150. The fine for not having one can be up to £5,000. When you factor in the risk of being unable to let or sell your property at all, getting the certificate in place is a straightforward decision.

Understanding MEES: The Rules That Catch Commercial Landlords Out

MEES — Minimum Energy Efficiency Standards — are the regulations that prevent landlords from letting commercial properties below a certain energy efficiency threshold. They’re enforced under Part 3 of the Energy Efficiency (Private Rented Property) (England and Wales) Regulations 2015, and they’ve been tightening in stages:

From 1 April 2018: Landlords could not grant a new tenancy to a new or existing tenant if the property had an EPC rating below E
From 1 April 2023: Landlords can no longer continue to let a sub-standard property (rated F or G), even under an existing lease — not just new tenancies

This second milestone catches a lot of landlords off guard, which is why we’ve included it in the myths section below as well. As Higgs LLP note in their MEES guidance, if you have an F or G rated property with a long-standing tenant still in occupation, you are already in breach of the regulations unless a valid exemption is registered on the PRS Exemptions Register.

Looking ahead, the proposed trajectory raises the bar significantly:

2027: Minimum EPC rating of C for all new commercial tenancies
2030: Minimum EPC rating of B for all commercially let properties

It is worth noting that these 2027 and 2030 proposals were consulted on under the previous government, and implementation timelines may shift. However, the direction of travel is clear, and the sensible approach is to plan ahead now rather than wait for confirmed legislation. Retrofitting older commercial buildings takes time to plan, procure, and fund — starting that process early puts you in a far stronger position.

Five Common Myths About Non-Domestic EPCs

Over 16 years of carrying out assessments across the West Midlands, we’ve heard plenty of misconceptions. Here are the ones that come up most often.

Myth 1: “My workshop or industrial unit is automatically exempt.” This one catches a lot of Black Country property owners out. The exemption for industrial sites and workshops applies only to buildings that do not use much energy. If your unit has fixed heating, cooling, or mechanical ventilation, it is very likely to need an EPC. Always check before assuming.

Myth 2: “I need a new EPC every time I re-let the property.” Not true. EPCs are valid for 10 years. If a valid certificate already exists for the property, it does not need to be renewed for each new tenancy or sale — provided it is still within that 10-year window and the building has not been significantly altered. This is confirmed in Higgs LLP’s guidance on MEES for commercial landlords.

Myth 3: “MEES only applies to new tenancies — my long-standing tenant means I’m fine.” This was true until April 2023. Since then, MEES regulations apply to all continuing commercial lets. If your property is rated F or G and your existing tenant is still in occupation, you are in breach.

Myth 4: “2030 is ages away — I’ll deal with it later.” With only 8.4% of commercial offices currently rated B or above, the majority of commercial landlords across England and Wales — including many in the West Midlands — will need significant investment to meet the proposed 2030 standard. Contractors are in demand, planning takes time, and funding schemes have application processes. Those who start planning now will manage the cost and disruption far more effectively than those who scramble at the last minute.

Myth 5: “The recommendations on the EPC are legally binding.” They are not. As set out in the GOV.UK guide to EPCs for non-dwellings, the improvement recommendations on a Non-Domestic EPC are entirely advisory. There is no statutory requirement to carry out any of them. The important distinction is that if your building is rated below the current MEES minimum (E), you must improve it to that threshold before continuing to let it — but the EPC recommendations themselves are a guide, not a legal obligation.

Choosing the Right Non-Domestic EPC Assessor in the West Midlands

Not all assessors are the same, and for commercial properties it really does matter that you use someone with the right level of accreditation and genuine hands-on experience of the building types in your area.

Look for an assessor who:

Is accredited by a government-approved accreditation scheme (Stroma Certification, Elmhurst Energy, Quidos, or CIBSE Certification)
Holds the appropriate level of qualification for your building type — the complexity of non-domestic assessments varies and assessors are qualified to different levels accordingly
Has demonstrable experience with similar commercial properties in your region
Can give you a clear turnaround time — particularly important if you’re working to a sale or letting deadline

The West Midlands has a genuinely varied commercial property landscape. From the older solid-wall manufacturing and light industrial units across the Black Country — in areas like Dudley, Sandwell, Walsall, and Wolverhampton — to the mix of retail, office, and mixed-use stock across Birmingham, Solihull, Coventry, Stourbridge, and Kidderminster, each building type presents its own assessment challenges. An assessor who knows the region and its building stock will carry out a more accurate assessment and flag the issues most relevant to your property.

We’ve been carrying out non-domestic EPC assessments across the West Midlands for over 16 years. Our clients consistently tell us that what they value most, beyond the technical expertise, is that we make the whole process easy — we’re straightforward to deal with, we explain things clearly, and we get the certificate back to them without delay.

To Sum Up

Non-Domestic EPCs are a legal requirement for most commercial properties being sold or let in England and Wales — and the compliance landscape is getting stricter, not more relaxed. The current E minimum is already catching out landlords with older stock, and the proposed trajectory to Band B by 2030 will require the majority of commercially let buildings to undergo meaningful energy efficiency improvements.

The good news is that understanding where you stand is straightforward, and getting the right advice early makes the process far less daunting. Whether you’ve just been told you need a certificate urgently, you’re concerned about how your existing property rates under current MEES rules, or you’re planning ahead for the 2030 changes, getting a proper assessment from an experienced local assessor is the logical first step.

With over 16 years of experience carrying out non-domestic EPC assessments across the West Midlands — from small retail units in Stourbridge to light industrial premises across the Black Country — we’ve helped hundreds of commercial landlords and business owners understand exactly where they stand and what they need to do. We’d be glad to help you do the same. Contact us for a non-domestic EPC assessment.
