Non-domestic EPCs and MEES
What does a commercial EPC cost?
Non-domestic EPCs are priced per building, not per square foot, because the work is modelling rather than measuring. Floor area matters, but so do the number of zones, how many heating and cooling systems serve them, whether anyone can find a floor plan, and how much of the survey has to be done on site. Below is what assessors actually price and what the minimum energy efficiency standard requires of you as a landlord. Then get quotes for your actual building.
How it works
- Tell us about the building: type, rough area, why you need the certificate, whether plans exist. Two minutes, no account.
- We pass your details to commercial energy assessors covering the property's location, and to no one else.
- They confirm the scope and quote you directly. Compare, choose, or walk away.

What sets the fee for a commercial EPC, 2026
Last updated
Non-domestic EPC fees are quoted per building because the work is a modelling exercise, not a checklist. Two units of identical floor area can differ by a wide margin depending on how many zones the assessor has to model, how many systems serve them, and whether anyone can produce a plan. This table sets out what assessors price, why each factor moves the fee, and what to ask for so competing quotes cover the same scope.
This is a cost driver table, not a price table. Each row names a factor that commercial energy assessors price into a fee, states why it moves the number, and gives the wording that pins down scope so quotes are comparable. We publish no fee figures because non-domestic EPC pricing is genuinely building-specific and any single range would mislead readers with atypical properties. Regulatory statements on this site are cited to gov.uk guidance and were checked on the date shown. For your number, get quotes for your actual building.
| Fee driver | Why it moves the price | What to ask for |
|---|---|---|
| Floor area and number of storeys | Area drives survey time and the amount of geometry to model. Multiple storeys and irregular footprints add more than the raw square metres suggest, because each floor has to be drawn and zoned. | A fee based on the actual measured area, and confirmation of what happens if the area on site differs materially from what you quoted. |
| Number of thermal zones | Modelling is done zone by zone. An open-plan warehouse is a handful of zones; the same area split into cellular offices, meeting rooms, a server room and a kitchen can be many times more. This is the factor most often underestimated by whoever requested the quote. | The assessor's assumption about zone count, and whether the fee changes if the building turns out to be more cellular than described. |
| Heating, cooling and ventilation systems | Each distinct system serving the building has to be identified, specified and modelled. A single gas boiler and radiators is quick. Multiple air conditioning systems, mixed-mode ventilation, heat pumps, comfort cooling in some areas and not others, and separate systems per tenancy all add work. | Confirmation of how many separate systems are included in the fee and what happens if more are found on site. |
| Whether drawings exist | The biggest single swing. With CAD or accurate PDF plans, the assessor models from them. With no plans, they measure the building themselves and draw it up, which can multiply the survey time. | Whether the fee assumes plans are supplied, and a separate figure for the measured survey if they are not. |
| Modelling method and assessor accreditation level | Non-domestic assessments are produced under the government's approved methodology. Simpler buildings are modelled with the standard tool; buildings with complex services or unusual features may require dynamic simulation modelling and an assessor accredited at a higher level. Ask which applies to yours, since the two are different pieces of work. | The assessor's accreditation scheme and level, and confirmation that it covers your building type and services. |
| Access, occupancy and out-of-hours working | The survey needs access to plant rooms, roof voids, ceiling voids and every tenanted area. Coordinating access across occupied units, or surveying outside trading hours, adds time and sometimes a second visit. | How many visits the fee allows, what access is required, and the charge for an abortive or repeat visit. |
| Number of separately let units | Separately let units commonly require their own certificates. Assessing several units in one visit is far more efficient than several separate visits, so how the instruction is bundled matters to the price. | A per-unit rate for a single mobilisation, and clarity on which units are included. |
| Turnaround and deadline pressure | A certificate needed for a deal exchanging this week is priced differently from one with a month's notice, because it displaces other work in the assessor's diary. | The lodgement date the fee assumes, and the premium for a faster turnaround, stated up front. |
| Advice beyond the certificate | An EPC comes with a recommendation report, but interpreting it for a MEES improvement plan, modelling the effect of specific measures, or supporting an exemption registration is consultancy and is priced as such. | A separate line for any improvement modelling or MEES advice, so the certificate fee itself stays comparable. |
- Government guidance states that landlords of non-domestic rented properties have only been permitted to grant a new tenancy, or to extend or renew an existing tenancy, if their property has at least an EPC E rating, unless they have registered a valid exemption.
- From 1 April 2023 the non-domestic minimum energy efficiency standard applied to all privately rented non-domestic properties, even where there had been no change in tenancy (gov.uk landlord guidance).
- An EPC is valid for 10 years (gov.uk), so the certificate that supported a letting a decade ago is not evidence of compliance today.

Common questions
How much does a commercial EPC cost?
Fees are quoted per building, because the work is a modelling exercise rather than a standard survey. The main drivers are floor area, the number of thermal zones, how many separate heating and cooling systems serve the building, whether usable drawings exist, access arrangements and the turnaround required. Supplying floor plans is normally the single most effective way to reduce a quote. Get quotes for your actual building rather than relying on a published range.
What EPC rating does a commercial property need to be let?
Government guidance states that landlords of non-domestic rented properties have only been permitted to grant a new tenancy, or to extend or renew an existing tenancy, if the property has at least an EPC E rating, unless they have registered a valid exemption. From 1 April 2023 the requirement applied to all privately rented non-domestic properties, even where there had been no change in tenancy.
How long does a commercial EPC last?
An EPC is valid for 10 years. Search the national register before instructing a new assessment, because a certificate lodged within the last decade may still be usable. Validity is a separate question from compliance: an old certificate can be valid and still sit below the minimum standard for letting.
What happens if a commercial property is below the minimum standard?
The landlord must either improve the property to the standard or register a valid exemption on the PRS Exemptions Register before relying on one. Enforcement sits with Local Weights and Measures Authorities, which may serve a compliance notice up to 12 months after a suspected breach, and non-compliance can result in financial penalties. Amounts are not set out in the landlord guidance we cite, so check the current guidance or take advice.
Do I need a separate EPC for each unit in a building?
Separately let units commonly require their own certificates, and how a building divides into lettable units is a question to settle with the assessor at the quoting stage. Assessing several units during a single visit is materially more efficient than instructing them one at a time, so bundle the instruction if you can.
Is this quote service really free?
Yes, free to you and with no obligation to instruct anyone. We pass your details only to relevant commercial energy assessors, who contact you directly. We may receive a fee from those providers, which is how the service is funded.
