Commercial EPC Exemptions: When You Don’t Need One
Most commercial buildings need an EPC (Energy Performance Certificate — the A-to-G energy rating required to sell or let a property) when they’re sold or let — but there are genuine exceptions. Before you rely on one, two warnings. First, the word “exemption” is used for two completely different things, and people mix them up constantly. Second, the genuine exemptions are narrower than most people think — the majority of owners who arrive at this page hoping their building is exempt find that it isn’t. This page explains both kinds of exemption plainly, walks through every category, and tells you honestly when an exemption won’t apply.
Two kinds of “exemption” — don’t confuse them
Exempt from needing an EPC at all — the building type means no certificate is required.
A MEES exemption — the building has an EPC, but it’s rated below the legal minimum (E) set by the Minimum Energy Efficiency Standard (MEES), and the landlord registers an exemption so they can still let it. That’s a different process, covered further down and on our minimum EPC rating for commercial property page.
Getting these the wrong way round is a common, expensive mistake — so we keep them separate here.
Buildings that don’t need a commercial EPC — the full list, plainly
A commercial building generally does not need an EPC if it falls into one of the categories below. Read the detail, not just the heading — each one is tighter than it first sounds.
Places of worship. Buildings officially used as places of worship and for religious activities don’t need an EPC. The exemption covers the worship use itself — a church hall let out commercially for events, or offices attached to a religious building, may still fall outside it. If the building earns rent as ordinary commercial space, don’t assume.
Temporary buildings (two years or less). A building with a planned time of use of two years or less — think site cabins, temporary classrooms, short-life marquee-style structures — is exempt. The test is the planned life of the building, not how long you’ve owned it or how long the current tenant is staying. A permanent building on a short lease is not a temporary building.
Small stand-alone buildings under 50 m². A stand-alone building with less than 50 m² of useful floor area (that isn’t a dwelling) is exempt. Both words matter: it must be physically separate — a 40 m² unit within a larger block or terrace doesn’t qualify — and under 50 m² of useful floor area. A kiosk or small detached lock-up often qualifies; a small shop in a parade usually doesn’t.
Industrial sites, workshops and non-residential agricultural buildings with low energy demand. The classic examples are an unheated warehouse, a workshop heated only by localised process equipment, or a barn. The key phrase is low energy demand: the exemption is about buildings that don’t use energy to condition the space people occupy. Add office space with heating and air-conditioning inside that warehouse, and the picture changes — the conditioned part typically needs assessing.
Buildings due to be demolished. A building being sold or let ahead of demolition can be exempt, but only where the pieces are genuinely in place: the seller or landlord holds the relevant planning consents, demolition is realistically intended, and the site is to be redeveloped. “We might knock it down one day” does not qualify — this exemption is evidence-led.
Listed buildings and buildings in conservation areas — the special case. This is the most misunderstood exemption of all, so it has its own dedicated guide: EPCs for listed commercial buildings. The short version: listed status is not an automatic exemption. A listed building is only outside the requirement insofar as complying with minimum energy performance requirements would unacceptably alter its character or appearance — a judgement that has to be made case by case, and in practice many listed commercial buildings still need (and benefit from) an EPC. If you own or manage a listed commercial property, read the dedicated page before relying on the exemption.
Exemptions are narrower than people think
It’s worth being blunt, because it saves our clients money and stalled deals: most commercial buildings are not exempt. The categories above are deliberately tight — a building that is heated or cooled for the people in it, physically joined to others, permanent, and in ordinary commercial use will almost always need an EPC when sold or let. If you’re hoping to avoid the cost of a certificate, an exemption is rarely the answer; and claiming one that doesn’t hold up can stall a sale, void a marketing launch, or expose a landlord to enforcement. The good news is the check is quick — tell us about the building and we’ll give you a straight answer, and if you do need an EPC it’s a fixed fee, not an open-ended cost.
What if my building is empty?
A vacant building still needs a valid EPC at the point you market it for sale or let, unless one of the exemptions above genuinely applies. Being empty is not, by itself, an exemption.
MEES exemptions (the other kind)
Everything above is about whether a building needs an EPC at all. MEES exemptions are different: they apply where a building has an EPC but it’s rated F or G, below the current legal minimum of E for lettings. Normally you can’t let that building — but a landlord may be able to register a MEES exemption to let it lawfully for a limited period. The main routes are: – The “7-year payback” / all-improvements-made exemption — you’ve made all the energy improvements that pay for themselves within seven years (or there are none that do), and the building is still below E. – The devaluation exemption — an independent surveyor’s evidence shows the required improvements would reduce the property’s market value by more than 5%. – The consent exemption — a third party whose consent is needed (a tenant, lender, superior landlord or planning authority) has refused it, or attached conditions you can’t reasonably meet. – The new-landlord exemption — someone who has just become a landlord in specific circumstances (for example by buying a tenanted building) gets a temporary six-month exemption to sort out compliance.
Every one of these must be registered on the national PRS Exemptions Register with supporting evidence before it applies — an unregistered exemption is no exemption at all. Most last five years (the new-landlord route lasts six months), they don’t transfer to a new owner, and the register is public. We can assess your building, tell you which (if any) genuinely applies, and — often the cheaper, cleaner answer — what it would actually take to reach an E instead. See the minimum EPC rating for commercial property guide for the full MEES picture, and commercial EPC regulations 2030 for where the minimum is proposed to go next.
Not sure which applies to you?
Exemptions are specific, evidence-led and time-limited, and getting one wrong can stall a sale or letting. Tell us about the building and we’ll confirm whether you need an EPC, whether an exemption applies, and the simplest compliant route.

Frequently asked questions
When is an EPC not required for a commercial property?
An EPC isn’t required for places of worship, temporary buildings planned for two years’ use or less, stand-alone buildings under 50 m², low-energy industrial and agricultural buildings, and some buildings genuinely due for demolition. Most ordinary commercial buildings don’t fall into any of these categories.
Are commercial properties exempt from EPCs?
Most are not — a commercial property generally needs a valid EPC to be sold or let. Only a handful of specific building types are exempt, and each exemption has conditions that are tighter than they first sound.
Which commercial properties are exempt from needing an EPC?
Places of worship, temporary buildings (two years or less), stand-alone buildings under 50 m², low-energy industrial or agricultural buildings, and buildings due for demolition with consents in place. Listed buildings are a special, conditional case — not an automatic exemption.
Are listed buildings exempt from EPCs?
Not automatically — a listed building is only outside the requirement where compliance would unacceptably alter its character or appearance, judged case by case. Many listed commercial buildings still need an EPC — see our EPCs for listed commercial buildings guide.
Does an unheated warehouse need an EPC?
Usually not — an industrial building with genuinely low energy demand, such as an unheated warehouse or workshop, is exempt. Heated or air-conditioned areas inside it, such as offices, can still need assessing.
Does an empty commercial building need an EPC?
Yes, when you market it to sell or let, unless a genuine exemption applies. Being vacant isn’t an exemption in itself.
What’s the difference between an EPC exemption and a MEES exemption?
An EPC exemption means the building doesn’t need a certificate at all. A MEES exemption means the building has an EPC rated F or G, and the landlord has registered a specific, evidenced reason to let it despite being below the minimum E.
Can I let a commercial property rated below E?
Only if you register a valid MEES exemption on the PRS Exemptions Register first — otherwise it’s unlawful. See our minimum EPC rating page for the rules and the improvement route.
How do I register a MEES exemption?
You register on the national PRS Exemptions Register with supporting evidence for the specific exemption you’re claiming, such as an improvements-payback assessment or a surveyor’s devaluation report. Most exemptions last five years and don’t transfer if the building is sold.
Do I need an EPC to sell an exempt building?
If the building genuinely falls within one of the exemption categories, no EPC is needed to sell or let it — but be ready to show why it qualifies, because buyers’ solicitors will ask. If it doesn’t clearly qualify, the safe and usually cheaper route is simply to get the certificate.
