Cleanroom Installation UK | Survey to Validated Handover | PackSealer
Cleanroom installation UK
Cleanroom installation runs from a site survey to a validated handover: confirm the ISO class, design and build the envelope in the UK, fit the HEPA filtration, set the air changes, and prove the room to ISO 14644-1. PackSealer installs Monmouth Scientific modular cleanrooms across the UK. Most Cleanroom Kits go up in a day or two with our phone support, from £17,560 ex VAT. Facility-scale builds we install and validate end to end.
What cleanroom installation actually involves
A cleanroom installation is the full path from an empty floor to a room that holds its particle count under load and passes an ISO 14644-1 test. Walls are the easy part. Six things happen in order: survey and scope, design, manufacture, delivery, build and commissioning, then validation and handover.
The part most buyers underestimate is commissioning. A cleanroom only works once the air is balanced. Clean Air Modules are set with an anemometer until the room hits its target air changes per hour, the pressure cascade is dialled in so clean spaces stay positive to dirty ones, and the HEPA filters are integrity-tested. Skip that step and the envelope looks finished while the room quietly fails its first validation.
Monmouth Scientific cleanrooms are engineered to make that path predictable. The aluminium framework, HEPA-filtered ceiling, gasketed doors, and control panel are manufactured as one system at Monmouth's Somerset works, so the parts fit first time and the commissioning is repeatable from one build to the next.
Two ways to install: self-assemble the kit, or we build it
A Monmouth Cleanroom Kit is built to be assembled by your own team. Most installers would rather not tell you that. Two people, basic tools, a day or two on site, and free phone support from the manufacturer while you build it. For a single ISO 7 or ISO 8 room on a prepared floor, you may not need to pay for installation at all.
A paid install earns its place in four cases. Facility-scale builds with multiple zones and integrated HVAC. Sites that need a validated handover with IQ/OQ paperwork signed off at completion. Tight production deadlines where a trained crew on site beats your team learning the system. And the straightforward preference to hand the whole job to one supplier and get a working, tested room back.
On a scoping call we will tell you which of those you are. If the kit route fits, we say so, quote the kit, and point you at the assembly guide. If the build genuinely needs a crew, we scope the install and the validation together. One supplier, survey to sign-off.
The five stages of a cleanroom installation
Every PackSealer cleanroom install runs through the same five stages, kit or facility build. Each one, with rough timings per route:
| Stage | What happens | Cleanroom Kit | Facility build |
|---|---|---|---|
| 1. Survey & scope | Site visit or floor-plan review. We confirm the ISO class your process needs, the footprint, services, and which route fits. | Quote within a working week | Quote within a working week |
| 2. Design & manufacture | Room designed to your floor plan and built at Monmouth's UK works. Same factory for both routes. | 4 to 6 weeks | Part of an 8 to 14 week programme |
| 3. Delivery | Flat-packed kit or facility components delivered to site on a booked date. | Scheduled to your build date | Scheduled in the programme |
| 4. Build & commission | Frame, panels, doors, and HEPA modules assembled. Air changes set with an anemometer, pressure cascade balanced, filters integrity-tested. | 1 to 2 days self-assembly, or 3 to 5 days installed | Included in the programme |
| 5. Validation & handover | Particle count to ISO 14644-1, HEPA integrity test, IQ/OQ documentation issued. | Optional, £400 to £795 per visit | Included, full IQ/OQ pack |
The single biggest schedule risk is site readiness: a level non-shedding floor, the right power, and clear access for delivery. We confirm all three at survey so the build date holds.
Your UK cleanroom supplier and installer
Choosing a cleanroom supplier in the UK usually means picking between a design-build contractor who quotes everything as a project and a kit vendor who ships you a box and leaves you to it. PackSealer sits between the two. We supply Monmouth Scientific cleanrooms, UK-designed and manufactured, with kit prices published on the page, and we install and validate when the job calls for it.
We publish what a cleanroom costs because guesswork helps nobody. Cleanroom Kits run from £17,560 to £24,800 ex VAT. Facility-scale builds are quoted to scope, usually £40,000 to £500,000. Validation visits are £400 to £795. You can budget the project before you ever pick up the phone.
After handover, the relationship continues. Replacement HEPA modules, gasket kits, and door seals for every Monmouth build sit in UK stock, so a filter swap ships in days. Revalidation visits keep your evidence current for the next audit. Buy once, supported for the life of the room.

Common questions about cleanroom installation
A Monmouth Cleanroom Kit ships in 4 to 6 weeks from order. It then self-assembles in 1 to 2 days with two people, or installs in 3 to 5 days if our crew builds it. Facility-scale builds run 8 to 14 weeks from order to validated handover depending on scope. The variable is site readiness: a level floor, the right power, and clear access keep the build date on track.
A Monmouth Cleanroom Kit is designed for self-assembly. Two people, basic tools, a day or two on site, and free phone support from the manufacturer while you build it. A paid install makes sense for facility-scale builds, where you need a validated handover with IQ/OQ paperwork, on a tight deadline, or when you would rather hand the whole job to one supplier. We will tell you honestly which route fits on a scoping call.
A Monmouth Cleanroom Kit runs from £17,560 ex VAT for 12m² to £24,800 ex VAT for 25m², which you can assemble yourself. A managed install is quoted with the build. Facility-scale builds are quoted to scope, typically £40,000 to £500,000. Validation visits run £400 to £795 per visit. We publish these figures so you can budget before you enquire.
A managed installation covers the survey and scope, design and UK manufacture, delivery, the on-site build, and commissioning. Commissioning is the technical core: Clean Air Modules set with an anemometer to the target air changes per hour, the pressure cascade balanced, and HEPA filters integrity-tested. Where a validated handover is specified, it finishes with a particle count to ISO 14644-1, HEPA integrity testing, and IQ/OQ documentation.
Yes. PackSealer supplies and installs Monmouth Scientific cleanrooms UK-wide. The rooms are designed and manufactured at Monmouth's works in Somerset, and we coordinate the project from survey through to validated handover. Kits ship anywhere in mainland UK for self-assembly; managed installs and facility builds are scheduled with a site survey first.
Validation at handover is a particle count to ISO 14644-1, a HEPA filter integrity test, and IQ/OQ documentation for your quality file. Monmouth carries this out where it is specified. From there the room is yours to monitor: routine particle monitoring and recurring revalidation keep your evidence current for the next audit, and we schedule those visits with you. Validation visits run £400 to £795 each.
Yes. A modular cleanroom is a free-standing envelope built inside your existing space, so most installs go into a current unit or factory. It needs a level non-shedding floor such as vinyl, an adequate power supply, and enough height (allow 350mm above the room for the Clean Air Modules). We confirm all of this at the site survey before anything is manufactured.
No. PackSealer supplies Monmouth cleanrooms for purchase only. For short-term project work or interim capacity, ask about clean tents and flexible clean canopies as a lower-cost option. For permanent capacity, a Cleanroom Kit or a scoped build is the right route and typically pays back faster than rental over a 12-month horizon.
