AHU cleaning for kitchens and businesses in Nuthurst
We clean the parts of the unit where dirt and moisture gather: the filter section, heating and cooling coils, drain trays, fan and casing. Every clean comes with a TR19® certificate and before and after pictures in a report. The work covers drain trays, internal panels and filter sections, and common reasons people get in touch are plant that has been serviced but not cleaned and dust built up on fan impellers.
Work in a small place like Nuthurst starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Think of the report as the system’s health record: dated, with photos, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

Nuthurst: your questions answered
Can the work in Nuthurst be done at night or at weekends?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in Nuthurst needn’t be disturbed. Just call 0345 646 2711, or email photos with your opening times and we will plan around them.
Is AHU cleaning available in Nuthurst?
Yes. We work across London and the South East, and Nuthurst is part of that. Just call 0345 646 2711, or send details by email with a few details of the site.
How much notice do you need?
For planned work, earlier is better, particularly if your next visit is nearly due. For emergencies, we take calls 24/7.
Do you have a 24/7 line?
Yes. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line, and we will advise on what to do next.
Can one contract cover all our sites?
Yes. One number covers all your sites in our area, with visits on a regular schedule.
Do you do ventilation duct cleaning too?
Yes, the ductwork, grilles and diffusers the unit serves. The survey shows whether the ducts need cleaning now.
What is TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
What if parts of the system cannot be reached?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, which we can install.
What affects the cost of AHU cleaning
You will get a fixed price before any work starts. It’s based on:
- Site rules, permits and inductions
- Whether it’s a one-off visit or part of a schedule
- When the work can happen, such as evenings, overnight or weekends
- Travel, parking and unloading
Combining work into one visit or one programme can make for a more efficient booking. Tell us about everything you’d like looked at, and you will get one fixed quote.
What we need to know
Many jobs can be priced from pictures and some basics. Useful things to send:
- Any symptoms, from odd noises to smells or leaks
- How we’d reach plant on a roof or in a plant room
- Wide pictures of the system and the area around it
- The postcode and the type of business

Signs you need AHU cleaning in Nuthurst
Wherever there’s a cooling coil, there’s condensate. A blocked outlet or a badly sloped tray leaves standing water, and that is where slime and odours start.
The symptoms we are asked about most are:
- Odours coming through the supply air
- Fan sections that haven’t been cleaned in years
- Drain trays holding standing water
- Units that have only ever had filter changes
Wherever a school like St Andrew's CofE Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.
What your quote should include
- If the quote is a fixed price or an estimate
- Exactly which parts of the system are covered
- How areas they cannot reach will be recorded
- If they look at the system before pricing
Managing agents and facilities teams in Nuthurst
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
We also work for facilities teams across offices, schools and healthcare in Nuthurst and across West Sussex. Larger estates can be phased building by building around the people who use them.
What your team can do, and what needs us
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
Between visits
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Change filters on schedule and log each change
- Keep inspection doors on the unit in good order
- Do not ignore odours coming through the grilles
- Note any water around the unit or leaks below it
The report suggests a date for the next inspection or clean, based on what we found. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Keep the area around the intake clear. What’s near the intake ends up in the unit.

- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- We take after photos and issue the certificate and report.
