Different checks have different purposes.
This is a planning overview for commercial premises in England, checked on 20 October 2026. It is not a site-specific compliance certificate or a substitute for competent design, risk assessment or building-control advice. We’ll help identify the work within Oxyplumb’s scope and any specialist input needed.
| Topic | What to establish | Primary guidance |
|---|---|---|
| Gas equipment | Use a Gas Safe registered business with the qualifications for the work; agree maintenance responsibilities. | HSE: gas safety for employers (opens in a new tab) |
| Hot and cold water | Understand the system, assess Legionella and scalding risks, and maintain the control arrangements. | HSE: hot and cold water systems (opens in a new tab) |
| Hot-water installation | Review safety, expansion and discharge provisions for the proposed work. | Approved Document G: hot-water safety (opens in a new tab) |
| Accessible washrooms | Assess the complete room, access and fittings—not just a labelled equipment pack. | Approved Document M: access to buildings (opens in a new tab) |
| Energy performance | Confirm the applicable building-regulations edition and scope with the project designer or building control. | Approved Document L: energy performance (opens in a new tab) |
Published changes are not all in force yet.
The 2026 England regulations associated with the Future Homes and Buildings Standards generally come into force on 24 March 2027, with a later 24 September 2027 date for specified higher-risk building work and transitional provisions. The applicable route depends on the work and its circumstances.
Do not assume the publication of a new document means every existing commercial replacement must immediately follow it, or that it creates a blanket ban on replacing gas boilers. Ask the project’s competent adviser to confirm the requirements. The Building Circular 01/2026: commencement and transition (opens in a new tab) sets out commencement and transition.
Servicing, F-gas checks and energy inspections are different.
Government guidance requires energy inspections for air-conditioning systems with an effective rated output above 12kW, at intervals no greater than five years. How equipment is grouped and controlled matters. Routine servicing is not a substitute for that inspection by an accredited energy assessor. See Government guidance: air-conditioning inspections (opens in a new tab).
F-gas leak-check duties depend on refrigerant, charge and the equipment arrangements; not every unit has the same check frequency. See Government guidance: F-gas leak checks (opens in a new tab). We can discuss air-conditioning installation and servicing and clarify which separate inspections or specialist services you need to arrange.
Keep a useful handover file.
- An equipment list and the manuals for the installed models.
- Commissioning and test records relevant to the agreed work.
- Operating guidance and maintenance requirements.
- Clear responsibilities for ongoing checks, risk assessments and specialist inspections.
For a replacement project, use our plant-room planning guide. For a washroom refurbishment, see commercial washroom services. We’ll discuss the practical scope with you and flag matters requiring separate specialist advice.
