EPCs for gyms, leisure centres and swimming pools

Updated 19 October 2026 · SEO Dons Editorial

Leisure buildings follow the same EPC rules as other non-domestic buildings, but pools, air handling plant and council ownership add complications. This guide covers which certificate applies when. For hotels, bars and restaurants, see our hospitality EPC page.

When does a gym or leisure centre need an EPC?

An EPC is only required when a building is constructed, sold or rented out. GOV.UK adds one more trigger: changing the number of parts used for separate occupation, where the work provides or extends fixed heating, air conditioning or mechanical ventilation. Splitting a warehouse into a gym and a separately let climbing centre, with new heating to each, would be an example.

For gym operators, lease deals matter most. Government guidance treats assigning a lease as selling an interest in the building, so assignment needs an EPC, and so does sub-letting. Lease renewals and extensions are not treated as a sale or let for EPC purposes.

A fit-out on its own does not usually trigger an EPC. The same guidance says an internal refit with new heating, hot water, air conditioning or mechanical ventilation does not, unless the building is also converted into more or fewer parts for separate use. It adds that after a renovation or change of use an updated EPC would be preferable, even though not required.

Failing to make an EPC available to a prospective buyer or tenant can bring a fine of £500 to £5,000, based on rateable value (GOV.UK, checked 19 October 2026). A building over 500 square metres that is frequently visited by the public must also display its EPC, if one has been produced for a sale, letting or construction.

Does a public leisure centre need a Display Energy Certificate?

It may, as a separate duty. Regulation 14 of the Energy Performance of Buildings (England and Wales) Regulations 2012 applies to buildings occupied by public authorities and frequently visited by the public. Since 9 July 2015 it has covered buildings over 250 square metres. The occupier must display a valid DEC prominently and hold a valid advisory report.

A DEC is based on the metered energy the building used over the last 12 months, not a model. Over 1,000 square metres, the DEC lasts 12 months and the advisory report 7 years; between 250 and 1,000 square metres, both last 10 years. The first DEC needs a site visit, and the occupier supplies meter readings for every fuel.

If a council-owned centre is run by a trust or contractor, the question is who occupies it. The GOV.UK DEC guide puts the duty on the occupier, and says that where a public authority lets a building to a private company for business that is not a public service, no DEC is required. Where the position is unclear, the guide advises independent legal advice. Private occupiers may display a DEC voluntarily.

A DEC does not replace an EPC: you still need one to construct, sell or let, and its rating must be shown on the DEC. The GOV.UK guide (updated 10 August 2015) lists penalties of £500 for not displaying a DEC and £1,000 for not holding an advisory report. See our guide to Display Energy Certificates.

Why are pools and leisure centres harder to assess?

Sport England's pool design guidance says energy use in pool buildings is generally high per square metre compared with other building types, and that pool hall air temperature, moisture and air quality need careful control. Hall air is usually kept one degree above the water temperature to limit evaporation, and the hall is heated all year round.

An EPC models each zone separately, with its own activity and its heating, cooling, ventilation and hot water. A leisure centre might combine a pool hall, changing rooms, a gym, a sports hall, a café and offices.

That sets the assessment level. Government guidance defines Level 3 as simple heating, simple natural ventilation and small comfort cooling. Anything else is Level 4, including VRF cooling and central air conditioning with air handling units, so a pool hall with its own air handling plant is outside Level 3.

Where the standard SBEM method may not be sophisticated enough, a Dynamic Simulation Model (DSM) is used instead: a Level 5 assessment. Elmhurst Energy, an accreditation scheme, lists atria, automatic shading, extensive thermal mass and highly glazed facades as Level 5 features. A large centre with a glazed pool hall or an atrium can fall into that group. Our guide to SBEM Level 3, Level 4 and DSM explains the difference.

Why can a pool's EPC and DEC give different grades?

The EPC is an asset rating: it models the fabric and fixed services, and depends on energy for space heating, water heating, ventilation and lighting. The DEC is an operational rating built from meter readings.

Sport England notes that the share of unregulated energy in pool buildings is very high: electricity for pool water treatment could be 50% of total electricity use, yet is not controlled by the Building Regulations. That energy shows up in the DEC, but it is not among the uses the EPC rating is calculated from. For a sale, a letting and MEES, the EPC is the document that counts. Ask the DEC assessor whether the method's separable energy use rules apply to your site.

What does MEES mean for a let gym?

Since 1 April 2018 a landlord of non-domestic property can only grant, extend or renew a tenancy if the property rates at least E, unless a valid exemption is registered. From 1 April 2023 that covers every privately rented non-domestic property, even with no change of tenancy.

MEES covers properties legally required to have an EPC and let for between 6 months and 99 years. Exemptions, such as the 7-year payback test, must be registered on the PRS Exemptions Register before you rely on them. Our MEES compliance guide covers the evidence.

Larger gyms should watch the next step. The government's interim response, updated 18 June 2026, proposes that from 2031 private rented buildings over 1,000 square metres reach EPC B where cost effective, with smaller buildings staying at E. It is a proposal, not law, until secondary legislation passes. The interim EPC C milestone once proposed for 2027 will not be taken forward.

Which improvements have public pools been funded for?

On 23 March 2024 the Department for Culture, Media and Sport announced that 325 pools and leisure centres in England would share £60.5 million to improve their energy efficiency. The measures named included new heating systems, solar panels, better insulation, pool covers and efficient lighting. For your own building, the recommendation report that comes with the EPC lists suitable measures grouped by payback period, and it is the starting point for an F or G rated let building.

What does an assessor need to know about a leisure building?

The more an assessor knows up front, the more accurate the quotes. Have ready the floor plans, details of boilers, heat pumps, air handling and heat recovery, lighting and controls, and whether the whole building or one part is being sold or let. For a DEC, add 12 months of meter readings.

GOV.UK notes the type of assessor depends on the building's complexity and features. You can request quotes from accredited assessors through the form on this site; enquiries are passed to companies that do the work. Our hospitality EPC guide covers related venues.

Common questions

Does a small boutique gym in a high-street unit need an EPC?

Yes, if the unit is sold or let, or has just been built or split into separately serviced parts. A small unit with simple heating, natural ventilation and small comfort cooling fits the Level 3 definition. If it is let, it must meet the MEES minimum of E unless an exemption is registered.

Is an outdoor pool or lido covered by the EPC rules?

The rules apply to buildings, meaning roofed constructions with walls that use energy to condition the indoor climate, so an open-air pool tank is not one. Heated changing rooms or a café beside it can be. A detached building under 50 square metres is exempt.

Who provides the EPC when a gym operator takes a new lease?

The landlord, who must make a valid EPC available to prospective tenants at the earliest opportunity. If you later assign your lease or sub-let, those transactions need an EPC too.

Can a leisure centre hold a DEC and an EPC at the same time?

Yes. A DEC is needed for qualifying public buildings whether or not anything is sold or let, while an EPC is needed on construction, sale or letting. If the building has an EPC, its rating must be shown on the DEC.
