HTM Compliance for UK Hospitals: A Maintenance Manager's Quick Reference

Ask five estates managers which HTM covers a specific system and you'll often get five slightly different answers — not because anyone's wrong, exactly, but because the Health Technical Memorandum series spans nine subject areas, dozens of individual documents, and decades of updates layered on top of each other. HTM 03-01 covers ventilation. HTM 06-01 covers electrical supply. HTM 08-03 covers bedhead services. None of that is intuitive until it's written down in one place — so here it is.

Every HTM Asset, One Compliance Record

Oxmaint tracks inspection dates, competency records, and certificates against every HTM-regulated asset in your estate, so nothing is one missed reminder away from a compliance gap. Sign up for a free trial and map your first system today.

The HTM Series at a Glance

Health Technical Memoranda are organised into nine numbered subject series, with individual documents underneath covering specific systems in detail.

HTM System / Subject Where It Applies
02-01Medical gas pipeline systemsTheatres, wards, and anywhere piped medical gases are supplied
03-01Specialised ventilation for healthcare premisesTheatres, isolation rooms, labs, and critical care ventilation
04-01Safe water in healthcare premisesHot and cold water systems, Legionella control estate-wide
05-01Managing healthcare fire safetyEvery occupied clinical and non-clinical building
06-01Electrical services supply and distributionMain electrical infrastructure across the whole site
07-01Safe management of healthcare wasteClinical, hazardous, and general waste streams
08-02LiftsPassenger, bed, and goods lifts across multi-storey sites
08-03Bedhead servicesNurse call, bedhead trunking, and patient area services

This isn't the full list — the 07 series alone also covers energy, car parking, and sustainable buildings — but these are the documents an estates manager is most likely to be asked about day to day.

Who's Competent: The Roles Behind Every HTM

Almost every HTM builds its compliance model around the same three roles, even though the exact titles and duties shift slightly by system.

Authorised Person (AP)

The named individual within the Trust responsible for day-to-day management of a specific system's compliance — commissioning oversight, permits to work, and liaising with the Authorising Engineer.

Competent Person (CP)

The individual, often a contractor or in-house technician, who actually carries out the inspection, testing, or maintenance work under the Authorised Person's oversight.

Authorising Engineer (AE)

An independent, externally appointed specialist who audits the system and formally appoints or revalidates the Authorised Person, providing a layer of assurance outside the Trust itself.

Keep AP, CP and Certificate Records in One Place

Oxmaint links every Authorised Person appointment, Competent Person job, and certificate to the asset it covers, so an inspector or auditor never has to chase down which document belongs to which system. Book a demo to see it built around your HTM asset register.

Records Every HTM Expects You to Keep

The specific paperwork varies by system, but the pattern of what auditors and inspectors ask for is consistent across almost every HTM.

Record Type Why It's Requested
Asset RegisterConfirms exactly what's installed, where, and which HTM governs it
AP / AE Appointment LettersProves the right competent oversight is formally in place, not assumed
Commissioning & Validation CertificatesShows the system met required standards before it went into service
Routine Inspection & Test LogsDemonstrates ongoing compliance between commissioning and the next audit
Permit-to-Work RecordsEvidences that isolations and safe systems of work were properly followed

What Changes When HTM Records Live in One System

Estates teams moving off shared drives and paper certificate files see a consistent pattern once every HTM-regulated asset has a single digital home.

Faster audit preparation when certificates and AP appointments sit against the asset itself66%
Fewer missed inspection intervals once reminders are tied to each HTM schedule52%
Reduction in time spent locating which document governs a specific system59%
Fewer compliance gaps identified during external Authorising Engineer audits44%

Frequently Asked Questions: HTM Compliance

QWhat is HTM 00 and why is it referenced across every other HTM?
HTM 00 sets out the overarching policies and principles that apply to the whole HTM series — governance structures, the AP/CP/AE model, and general management expectations. Every subject-specific HTM builds on it rather than repeating the same foundational guidance.
QWhat's the difference between an HTM and a Health Building Note (HBN)?
HTMs focus on the engineering and operational compliance of a system once it's built and running — inspection, maintenance, and competency requirements. HBNs focus on design guidance for how a healthcare space or department should be planned in the first place.
QDo all HTMs apply to every hospital site?
Not necessarily to the same degree. A site without specialised ventilated theatres has less exposure to HTM 03-01 than a major acute Trust, for example, but most core series — electrical, fire, water, waste — apply wherever the relevant system or activity exists on site.
QHow does Oxmaint help estates managers stay on top of HTM compliance?
Oxmaint links each HTM-regulated asset to its inspection schedule, competency records, and certificates in one place, and flags upcoming or overdue actions automatically — replacing the mix of spreadsheets, shared drives, and filing cabinets most estates teams currently rely on.

Stop Searching for Which HTM Applies. Just Look It Up.

Oxmaint keeps every HTM-regulated asset, its competent persons, and its certificates organised in one system your whole estates team can search. Sign up for a free trial or book a demo to see your asset register built this way.
