AHU cleaning for kitchens and businesses in Wisborough Green
No two plant rooms are the same, whether it’s a compact unit in a ceiling void or a big unit on the roof. We look at the unit first, from photos or a site visit, and give you a fixed quote, so you know where you stand. If you are dealing with units that have only ever had filter changes and rooms that smell stuffy when the system runs, we can help.
For a building in or near Wisborough Green, access is agreed in advance and the visit is planned around the journey.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

Between visits
Simple habits between visits make a real difference. We recommend:
- Keep filter changes on time and recorded
- Make sure the unit’s access doors open easily
- Check the drain tray is emptying during routine visits
- Don’t store bins or materials near the intake
We recommend when the unit should next be inspected or cleaned, taking into account how dirty it was. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.
Staff cleaning versus specialist work
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.

Managing agents and facilities teams in Wisborough Green
Multi-site operators often want one contractor and one number. We cover South East England and London, so a run of sites can go into one programme and kept on a regular cycle.
Records are where multi-site compliance often slips. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.
Questions from Wisborough Green
Will you come out to Wisborough Green?
Yes, Wisborough Green is part of our area, however small the site. The journey is planned ahead, so a few details about the route help.
Do you do school ventilation cleaning in Wisborough Green in the summer holidays?
Yes. The holidays are the usual time for school work. Food Standards Agency records list about 2 schools, colleges and universities with registered kitchens within about a mile and a half of Wisborough Green. Tell us your holiday dates and we’ll book the visit for when the site is empty.
What is TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.
Do you clean the ductwork as well?
Yes. Ductwork is cleaned through access panels, and any sections we can’t reach are noted in the report, with new panels fitted where needed.
Can you clean without disrupting the building?
Yes, wherever it helps the building. We plan the shutdown window with you.
Do you offer emergency callouts?
Yes, 24/7. Our office is open from 8am to 6pm on weekdays, with the emergency line covering every other hour.
What do you do to protect the area?
With sheeting and covers, before anything else happens. We keep the work contained and clean down when we finish.
When should our AHU next be cleaned?
TR19® Air takes a risk-based approach, so it depends on inspection rather than a fixed interval. We recommend a next date in each report.

What happens on the day
There are three stages on the day: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, while signing off means the written report and photos. Most of the time goes on the work itself, and that takes from a few hours for a compact unit to a day or more for a large one. In a small place like Wisborough Green, the journey is planned ahead and the visit arranged around the site’s hours.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Getting ready for the visit
- Clear the space around the work
- Mention any locked doors, roof access or ceiling voids
- Let us know when the site is closed or quiet
Getting a quote
To get a fixed quote, give us a ring on 0345 646 2711 or drop us a line with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. You’ll typically have a quote within one working day.

Rooftop and plant room units
Units on roofs and in plant rooms can be awkward to reach. We plan safe access as part of the survey so the quote reflects it.
Heating and cooling coils
Dirt on a coil slows the air and makes it harder for the coil to heat or cool. A clean gets air moving through the coil properly again.
