AHU cleaning for kitchens and businesses in Lewes
We clean the parts of the unit where dirt and moisture gather: filters, coils, drain trays, fans and the internal panels. Every clean comes with a TR19® certificate and before and after pictures in a report. If you’re dealing with plant that needs cleaning after a refit and condensate trays that won’t empty, we can put it right, from internal panels, filter sections and drain trays onwards.
In a town like Lewes, ventilation cleaning normally means offices, schools, surgeries, care homes and leisure buildings. Each has supply and extract ductwork that collects dust and debris, and TR19® Air sets out how to inspect and clean them.
The sign-off is always in writing: a dated report with photos of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

Why act early in Lewes
Leave an AHU uncleaned and the dirt does not stay put. It moves on into the ductwork and out into the rooms, which is why the unit and the ducts are best cleaned together. With a fire risk assessment or inspection due, getting the work done first puts you on the front foot.
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we will explain each part.

Lewes questions
Can you come to Lewes after we close?
Yes. We work evenings, overnight and at weekends. That way a site in Lewes doesn’t have to lose a day’s trading. Just ring 0345 646 2711 or send us an email with your opening times and we’ll plan around them.
Do you offer AHU cleaning in Lewes?
Yes. We work across London and the South East, and Lewes is part of that. Get in touch with the details and we’ll arrange a survey.
How much notice do you need?
Earlier is better, especially for out-of-hours work. We typically quote within one working day, and there’s a 24/7 line for emergencies.
Do you have insurance?
Yes. We carry full insurance, and we have been trading since 2009.
Can you look after several sites?
Yes. Our area covers London and the South East, so we can schedule a run of sites on one programme. Every site has its own report.
Do you look at the system first?
Yes, always. We diagnose before we treat: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
Is a quote from pictures possible?
Yes, for many jobs. Send wide shots, close-ups of any access panels and anything that worries you, and a fixed quote usually follows within one working day. Some sites still need a visit, and we’ll say so.
Do you give a certificate after the clean?
Yes. A TR19® certificate and photo report are sent after the clean, with any faults we noticed.
When it’s something else
A few issues sit outside what this work can do:
- The supply and extract ducts, quoted separately
- Airflow problems caused by the system’s design
- Problems with the unit’s controls or sensors
If in doubt, call 0345 646 2711 or drop us a line and we will say what we think.
What we work on in Lewes
- Dampers and louvres
- Internal panels
- Supply and extract fans
- Heating and cooling coils
- Filter sections
- Drain trays
Staff cleaning versus specialist work
Staff cleaning and specialist work aren’t the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
Between visits
Results last longer with the right care. Here’s what we suggest:
- File each AHU report in the maintenance log
- Report stiff or damaged access doors
- Check the drain tray is emptying during routine visits
- Note any water around the unit or leaks below it
You receive a TR19® certificate and a photo report after the clean. They belong in the plant or maintenance log.
Change or clean filters on time. Overloaded filters let more dirt through to the coils and fan.
Do you need AHU cleaning in Lewes?
Dirt in an AHU matters in two ways: the unit supplies the air people breathe, and a dirty unit has to work harder. For the people using the building every day, that’s the air they breathe for hours on end.
Signs it’s time to call us include:
- Dirty coils holding back the airflow
- Plant that needs cleaning after a refit
- Debris and leaves in the fresh air intake
- Condensate trays that will not empty
School buildings such as Lewes Old Grammar School are normally done in the holidays, so classrooms are not disturbed.

Managing agents and facilities teams in Lewes
Managing agents often deal with us directly. Send the address, what’s needed and how access works and we’ll come back with a fixed quote.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
The process
A visit follows the same order every time: sheeting and protection first, isolate whatever needs isolating, carry out the AHU cleaning, clear away and leave you the report. The visit itself takes from a few hours for a compact unit to a day or more for a large one. We arrive in Lewes once you’ve closed and leave the site ready for the morning.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- We take after photos and issue the certificate and report.
How to prepare
- Clear the space around the work
- Make sure someone can let us in and lock up afterwards
- Mention any sign-in, permit or induction we need
How to get a quote
Getting a quote does not take long. Call or email with a few details and you’ll usually have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
Advice
Ventilation in Lewes buildings
Food Standards Agency records list about 7 schools, colleges and universities and about 4 caring premises (care homes, nurseries and hospitals) registered as food businesses within about 1.5 miles of central Lewes. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Lewes, about 43 miles from central London, is within our usual area. The visit is fixed around your opening hours, not ours. The nearest hospital to Lewes is Lewes Victoria Hospital, about 0.5 miles west. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.
If you run an office near Lewes station, its supply ductwork can gather dust for years before anyone looks inside. Healthcare ventilation, from large hospitals like Lewes Victoria Hospital (about 0.5 miles west) to small clinics, depends on clean filters, coils and ducts.
