AHU cleaning for kitchens and businesses in Keymer
If the units serving a building in Keymer have only had filter changes for years, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full AHU clean takes in the whole unit. If you have dust built up on fan impellers and odours coming through the supply air, we can put it right, from internal panels, supply and extract fans and filter sections onwards.
Smaller buildings around Keymer often keep their ventilation units in a roof void or plant cupboard, where they’re easy to forget. Every unit, large or small, has filters, coils and a drain tray to keep clean.
A written report with pictures follows each visit, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

What we do, step by step
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes one overnight shift for many single units, with bigger plant phased. Visits to a place like Keymer are planned ahead, so we arrive with what the survey says the job needs.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
How to prepare
- Make sure equipment near the work can be switched off and left to cool
- Let us know about permits to work or site inductions
- Tell us the best time to work, such as after service or at a weekend

AHU cleaning in Keymer: local notes
Food Standards Agency data includes about 3 hospitals, care homes and childcare premises in Keymer and the streets around it, up to about 1.5 miles out. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Keymer is about 40 miles from central London, well within the area we cover across London and the South East. The visit is fixed around your opening hours, not ours. The Dene Hospital is the nearest hospital, about 3.2 miles north-west of Keymer. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.
For workplaces around Hassocks station with mechanical ventilation, cleaning can be done in the evening or at weekends. If you manage a school such as The Windmills Junior School, ventilation cleaning is best booked for the holidays.
Keymer is about 2 miles south of Burgess Hill, in West Sussex. Whether your site is in the middle of Keymer or further out, AHU cleaning is available to all kinds of commercial premises, from a single unit to a large public building. Our West Sussex coverage runs to 371 places, Keymer among them. We also work in Brighton, around 6 miles away.
All of BN6 is covered for AHU cleaning, from busy streets to back roads. Local streets include Flowers Close, The Quadrant and Kymer Gardens, all of which we cover for AHU cleaning. Close by, we work in Hassocks (1 mile west), Ditchling (1 mile east), Clayton (1 mile south-west), Hurst Wickham (1 mile north-west) and Westmeston (2 miles south-east). We also work in nearby towns such as Crawley (13 miles north), Horsham (13 miles north-west), Worthing (14 miles south-west), Haywards Heath (5 miles north), East Grinstead (15 miles north) and Shoreham-by-Sea (8 miles south-west).
Local landmarks in Keymer
Around Keymer, our work takes us to kitchens and buildings near The Greyhound Public House and Downlands Community School, among other places. For rail, the closest station is Hassocks station, roughly 0.5 miles west of the centre. A little further out are The Dene Hospital (3.2 miles north-west) and Clayton Castle (1.2 miles south-west). Green spaces nearby include Ditchling Beacon and Bedelands Farm Nature Reserve.
In-house cleaning or a specialist?
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that is where we come in.

Why deal with it now?
A slimy drain tray only gets worse. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Clearing it now is a much smaller job. In a smaller place like Keymer, a site that has to close is felt quickly.
When the work has to happen, how we reach it and how big the site is all affect the cost. Each of those is built into the quote, and the price is fixed before any work starts.
Why book with us
- CHAS and SafeContractor accredited, with ISO 9001
- Fully insured
- A fixed price before any work starts
- Trading since 2009

Different parts, different methods
Filters
Clogged filters reduce airflow, and dirt can get round the edges. We clean the frames and rails so the filters sit tight.
Internal casing and panels
We open each section through its doors and close them securely when we’re done, and check every one is shut.
For landlords and multi-site operators
Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept on a regular cycle.
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements, and we will send a fixed quote.
Do you need AHU cleaning in Keymer?
It matters for two reasons: the unit supplies the air people breathe, and a dirty unit has to work harder. For anyone working, learning or staying in a building in Keymer, that’s air they breathe for hours at a time.
If you notice any of these, it’s worth a diagnosis:
- Filters that are clogged or overdue
- Leaves and litter drawn into the unit
- Air handling units never cleaned inside
- Stale or musty smells from the ventilation
Healthcare buildings such as The Dene Hospital, about 3.2 miles north-west, depend on their ventilation; if you manage a surgery, clinic or care home near Keymer, yours matters too.
Comparing quotes

- How they set the interval to the next visit
- If the quote is a fixed price or an estimate
- What happens if part of the system can’t be accessed
When it’s something else
A few issues sit outside what this work can do:
- Dirty ducts beyond the unit itself
- A system that’s undersized for the building
- Breakdowns that need a mechanical engineer
If in doubt, call 0345 646 2711 or use the quote form and we will say what we think.

Do you work at weekends in Keymer?
Yes, we can come after you close and finish before you open. The work in Keymer can fit around your hours. Your opening times are the first thing we ask for.
How often do AHUs need cleaning?
Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. We recommend a next date in each report.
Do you offer emergency callouts?
Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we will talk you through the next steps.
Will the ventilation be off while you clean?
Yes. The unit has to be shut down and isolated before it’s opened. We agree the timing with your site team.
Do you do ventilation duct cleaning too?
Yes. We reach the ducts through access panels, and any sections we can’t reach are noted in the report, and new panels can be fitted.
