Opening a commercial gym: compliance, standards and budget

Opening a commercial gym is four projects run in parallel, and the one that most often delays an opening date is not the equipment but the public building safety approval. The four are the legal framework for operating a sports facility, equipment conformity to EN ISO 20957, public building compliance for the premises, and the equipment budget itself, which ranges from around 25,000 EUR to more than 500,000 EUR excluding VAT depending on format. This guide sets out each one, using the French regime as the worked example because it is among the most codified in Europe, with notes on where other markets differ.

The legal framework for operating a sports facility

In France, any establishment offering physical and sporting activities must be declared to the departmental state service, the DDETS, within two months of opening, under article L. 322-3 of the sports code. That declaration conditions the validity of insurance cover and registration in the national register of sports facilities. Most European countries have an equivalent registration or notification step; the detail differs, the principle does not.

Paid instruction requires a recognised qualification. In France that means a diploma registered in the national qualifications register, typically the BPJEPS fitness qualification with a strength training or group class specialism, the DEUST fitness professions or a sports science degree with a coaching specialism. The professional card that follows the activity declaration must be renewed every five years and displayed in the facility.

Professional liability insurance covering the operator, staff and users is mandatory under article L. 321-1. The certificate, the instructors’ qualifications, the internal rules and the price list must all be displayed visibly. Two further declarations are routinely forgotten in opening plans: music licensing. In France that means SACEM and SPRE; every European country has an equivalent collecting society and the obligation applies to any facility playing recorded music, which is every gym.

Public building compliance: the item that sets your opening date

A gym is a public building in the regulatory sense, classified in France as ERP type X, covered sports establishments. Obligations scale with the category, which is set by permitted occupancy: accessibility for people with reduced mobility, smoke extraction, exits and escape routes, alarm systems and a safety register. For categories 1 to 4, a safety commission visit is required before opening to the public, and a works authorisation must be filed with the town hall even where no planning permission is needed.

The practical point matters more than the legal one. Processing a works authorisation commonly takes two to four months, before the safety commission visit is scheduled. Anticipate that timeline before signing a commercial lease, and have a condition precedent written into the lease making it contingent on obtaining the operating authorisation. Projects that skip this step pay rent on a building they cannot open.

Equipment standards, and a widespread misreading

The classification deserves precision, because it is widely misreported, including in French language guidance that describes class S as semi professional and class I as institutional. Under EN ISO 20957-1 in its 2024 revision, class S designates professional and commercial use, class H designates domestic use, class I designates inclusive equipment usable by people with disabilities, and classes A, B and C describe accuracy of measurement. There is no semi professional class. For a commercial club, specify class S and reject class H equipment whatever the discount, since domestic class machines fail early under commercial duty cycles and undermine both insurance and warranty positions.

Equipment budget by format

These are equipment and flooring figures. They exclude building work, ventilation and air conditioning, changing rooms, reception furniture, access control and signage, all of which belong in the project budget rather than the equipment quotation. On a fit out of any size, the gap between the two is routinely 20 to 30 per cent.

A realistic opening sequence

Work backwards from the safety commission, not forwards from the lease. A workable sequence is: define the format and catchment, secure a building subject to a condition precedent on the operating authorisation, file the works authorisation, run the fit out design and the equipment layout in parallel, order equipment once the layout is fixed, lay flooring before equipment delivery, install and commission, obtain the safety commission approval, then open. Stock equipment ships in 5 to 10 working days, so equipment is rarely the critical path. The authorisation is.

What differs outside France

Three things. The registration regime for sports facilities varies from a simple business registration to a specific sports establishment declaration. Instructor qualification requirements range from strict national frameworks to sector self regulation. And public building safety approval is universal in principle but differs in category thresholds and in whether a pre opening inspection is mandatory. What does not vary is the equipment standard: EN ISO 20957 is a European standard and applies across the single market, as do EN 16630, EN 1177 and EN 14904.

Frequently asked questions

Can we open before the safety commission visit?

No, where the category requires it. Opening to the public without approval exposes the operator personally and voids insurance cover in the event of an incident. Build the visit into the programme rather than treating it as a formality at the end.

Do we need qualified instructors if the gym is unstaffed?

An unstaffed access model changes the staffing question but not the safety obligations, and any paid instruction, including personal training delivered on site by third parties, still requires the relevant qualification. Access control, emergency call provision and supervision arrangements have to be documented for an unstaffed facility.

What insurance is actually required?

Professional liability cover for the operator, employees and users. Provide your insurer with the equipment conformity documentation and the installation records; compliant, documented equipment is what keeps a claim straightforward.

How long does the whole process take?

Six to twelve months from decision to opening for a conversion project is realistic, with the works authorisation and safety commission accounting for the largest fixed block. Equipment lead times are a small part of that for stock items and a larger one for custom finishes.

Should we buy or lease the equipment?

Leasing preserves cash and matches payments to revenue, which suits a new operator with no trading history. It does not reduce the total cost of ownership: maintenance, wear parts and eventual renewal are unchanged. Compare offers on total cost across the full term, not on monthly payment.
