You’ve signed the lease, you’re working through the CQC application, and the decontamination room is the bit you suspect you’re under-budgeting for. This is the practical checklist we’d put in front of any dentist opening a squat practice or refitting a takeover, kit, room layout, records, and the statutory items you need in place before the first patient through the door.
Written so you can use it as a buying list, not as a textbook.
Two things to be straight on, because the rest of this article makes sense once they’re clear.
CQC registration. A new dental provider can’t legally treat patients without it. CQC say they take up to 10 weeks to process most applications, sometimes more, for budgeting purposes, plan for 10 to 16 weeks of real-world processing in 2026. Your equipment fit-out can happen in parallel; you just can’t start treating patients until you’re registered.
HTM 01-05 sets the operational rules. The 2013 edition is still the current operative version. It runs a two-tier framework: Essential Quality Requirements (EQRs) are the compliance floor every practice must meet; Best Practice is the level to progress towards over time. A new practice has the chance to design for Best Practice from day one, which is usually cheaper than retrofitting later.
HTM 01-05 sets premises requirements in its Chapter 5. The Best Practice expectation is a separate dedicated decontamination room with physical separation between clean and dirty zones; the EQR floor allows decontamination within the treatment room provided clean-to-dirty workflow is maintained. For a new build, design for Best Practice, it’s the standard CQC inspectors expect and it adds little to the build cost compared with retrofitting later.
The room essentials:
For any modern UK dental practice, a Class B vacuum autoclave validated to EN 13060 is the only practical choice. Class N machines can’t handle pouched or hollow loads, which means handpieces, 3-in-1 tips, and wrapped storage all go untreated. Modern dental workflow needs Class B.
Chamber sizing:
Our three Class B ranges sit on the practice equipment page, the Castellini C Series at the value end, the Stern Weber SW Series as a no-frills entry, and the Mocom B Classic where design matters because the unit is visible in a treatment-room-adjacent layout. The longer write-up on choosing between them is in our no-nonsense autoclave buyer’s guide.
Indicative budget: entry Class B £2,500: £5,500 ex VAT; premium with cloud traceability and water recycling £5,500, £9,000+. Add installation, commissioning, first-year validation and PVI to the spend.
HTM 01-05 positions the washer-disinfector as the preferred best-practice cleaning method because the process is automated, validated and repeatable. The integrated Tethys H10 Plus runs ultrasonic, wash, thermal disinfection at 90°C and dry in a single 41-minute cycle, validated to EN ISO 15883-1 and -2. For a new practice with the build budget to include a WD, it’s the cleanest answer, one machine, one cycle, one piece of compliance paperwork rather than running a separate ultrasonic alongside.
Indicative budget: £6,000: £10,000+ for an integrated WD.
For practices where the WD isn’t in this year’s budget, a standalone medical-grade ultrasonic cleaner is the alternative. Must meet HTM 01-05’s procurement specification: lockable interlocking lid, thermostatic temperature control with over-temperature cut-off, cycle data logger or printer for traceability, low-fluid auto cut-off. Do not buy a domestic or jewellery ultrasonic, it won’t pass a CQC inspection and isn’t designed for the load. Ring us about current options.
Indicative budget: £1,000: £2,200 for a compliant medical-grade ultrasonic.
HTM 01-05 §4.20 is explicit: “fill the reservoir with distilled water or RO water”. Mains water: even soft UK mains water, destroys autoclaves from the inside via limescale on the heating element. The element runs hotter to compensate, the cycle starts failing, validation goes south, and what should be a ten-year unit dies at five.
For a new fit-out, plumbed-in RO is the right answer. An under-sink unit suits a single-autoclave practice; a centralised RO system feeding multiple autoclaves and the WD makes sense for multi-surgery setups.
Indicative budget: £800: £2,500 for an RO system depending on size and configuration.
Yellow-bodied sharps containers manufactured to BS EN ISO 23907-1:2019 (the current standard, replacing the older BS 7320). UN 3291 transport classification. Sized to your throughput.
Collection by a licensed clinical-waste contractor. Keep waste transfer notes for at least two years, hazardous-waste consignment notes for three. The contractor provides them after each collection.
Single-use nitrile gloves (powder-free, latex avoided for allergy reasons), single-use aprons, fluid-resistant masks, eye protection. Wall-mounted glove dispensers in at least Medium and Large in the treatment room. Budget the consumables monthly, not as a one-off setup item.
Sealed cupboards or drawers in the clean zone, off the floor, for sterilised pouched items and single-use stock. Pouch shelf life depends on your practice’s own policy and storage conditions, typically several months for properly stored pouched items, with the date of sterilisation marked on every pouch.
The paperwork side is what catches new practices out at their first CQC inspection more often than the kit itself. Set up the systems before you treat the first patient:
Autoclave logbook, paper or digital, both fine. Daily entries for the Automatic Control Test and the Bowie-Dick or Helix steam-penetration test. Weekly entries for the air-leakage test. Operator signatures on every entry. Records retained at least two years per HTM 01-05.
Decontamination policy: a written SOP describing how your practice decontaminates instruments, who is competent to do it, what happens when a cycle fails.
Training records: for each operator who runs the autoclave or carries out decontamination tasks. Named, dated, signed.
Risk assessments and COSHH: for the working practices and any chemicals used.
Service certificates, validation reports, PVI certificates: once the kit is commissioned, these are the rolling annual paperwork.
The fuller picture is in our autoclave logbook requirements guide and our CQC inspection guide for practice managers.
These can’t be retrofitted after you start treating patients. Get them all sorted before commissioning:
Pressure Vessel Inspection (PVI) before first use. PSSR 2000 Regulation 8(1) is explicit: “The user of an installed system and owner of a mobile system shall not operate the system or allow it to be operated unless he has a written scheme for the periodic examination, by a competent person…” That’s not best practice; that’s the law. The autoclave needs its Written Scheme of Examination and the first PVI before clinical use.
Initial commissioning and validation of every piece of decontamination equipment (autoclave, WD, ultrasonic) per HTM 01-05.
PAT testing for all electrical equipment in clinical use. Sits under the Electricity at Work Regulations 1989; frequency is risk-based, not legally fixed at annual.
Decontamination policy in writing, signed, dated.
CQC Regulation 15 compliance: “All premises and equipment used by the service provider must be, (a) clean, (b) secure, (c) suitable for the purpose for which they are being used, (d) properly used (e) properly maintained, and (f) appropriately located for the purpose for which they are being used.” That’s the standard the inspector will measure you against on day one.
Patterns we see when new practices have struggled with the first CQC visit or with year-two equipment failures:
Ring us on 01274 265566 for a single conversation that covers the autoclave, the washer-disinfector or standalone ultrasonic, the RO supply, the room layout, the validation and PVI on installation, and the ongoing service arrangement. We do this kind of new-practice fit-out routinely and can quote kit, installation, commissioning and the first-year compliance bundle in one package.
For the first-year service bundle specifically: our published price for a B-type autoclave is £450 + VAT (£395 for N-type) covering service, PVI and validation in one visit. On the service and maintenance page.
