AHU cleaning for kitchens and businesses in Lenham
All the building’s air passes through the fan, so dirt on the impeller and housing gets spread around. Fan, housing and the surrounding panels are cleaned as part of the job, once the unit has been shut down and isolated. We are often asked to deal with dirty coils holding back the airflow and drain trays holding standing water, across dampers and louvres, drain trays and internal panels.
Visits to a place like Lenham are fitted around opening hours. The method doesn’t change: inspect first, clean, then record what was done.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

What affects the quote in Lenham
The survey tells us what the work involves. The main factors are:
- How easy every part is to reach
- The number of sites or systems
- How big the system is
- Parking and loading at the site
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.
Helping us quote
You don’t need the technical terms. Just send:
- Any symptoms, from odd noises to smells or leaks
- How we’d reach plant on a roof or in a plant room
- The postcode and the type of business
- Close-ups of filters, grilles, hatches or access panels
There’s no standard price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, and then send you a fixed quote. To start, phone us on 0345 646 2711, or send details by email.
Staff cleaning versus specialist work
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 will take a look and give you a fixed quote.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Your questions about AHU cleaning in Lenham
Can you work in Lenham outside opening hours?
Yes, we can come after you close and finish before you open. That way a site in Lenham does not have to lose a day’s trading. Just call 0345 646 2711 or send us an email with your opening times and we will plan around them.
Can ventilation in schools around Lenham be cleaned out of term?
Yes, and it’s the easiest time to do it. Food Standards Agency records list about 4 schools, colleges and universities with registered kitchens within about a mile and a half of Lenham. Booking early in the term gives the best choice of holiday dates.
Are you accredited?
We hold CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
Do you work in Lenham?
Yes. Our technicians work in Lenham, within the South East and London area we cover.
Do you offer maintenance contracts?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, depending on what the system needs.
What’s included in an AHU clean?
We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. Filters are cleaned or changed as agreed in the quote.
What information do you need?
Some photos and a quick description of the system, with the address and opening hours. We will ask for anything else we need.
What do you do with what you remove?
We contain it and take it with us. Grease, debris and waste water are collected as the work goes on rather than letting it spread.
What happens if it’s left?
A slimy drain tray only gets worse. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Clearing it now is a much smaller job. Light use slows the build-up but doesn’t stop it.
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re not sure what’s needed, give us a ring on 0345 646 2711, or email photos and we’ll give you an honest view and a fixed quote.
What you get with us
- CHAS, SafeContractor and ISO 9001
- We diagnose before we treat
- Out-of-hours work and a 24/7 emergency line
- We are fully insured

Lenham buildings and their air
Food Standards Agency records list about 4 schools, colleges and universities registered as food businesses across Lenham and its immediate surroundings (about a mile and a half). Buildings like these often rely on mechanical ventilation, which TR19® Air covers. We cover Lenham, about 39 miles from central London, as part of our work across London and the South East. We work evenings, overnight and at weekends, so the visit fits around the site.
If you manage shops or offices close to Lenham station, a TR19® Air inspection shows whether the ductwork needs cleaning. If you manage a school such as Lenham Primary School, ventilation cleaning is best booked for the holidays.
Lenham is about 7 miles south of Sittingbourne, in Kent. Whatever kind of site you run in Lenham, we can take on AHU cleaning. Visits can be booked for evenings, overnight or weekends so the site keeps running. Lenham is one of 922 places in Kent where we work for AHU cleaning. Our Maidstone page covers sites nearby, about 8 miles away.
Work in ME17 follows the same survey, fixed quote and written report as everywhere else we cover. That includes premises on High Street, Mitchell Close and Hatch Road and the roads around them. Nearby, we also carry out AHU cleaning in Leadingcross Green (1 mile south), Woodside Green (1 mile north-east), West Street (1 mile north-east), Lenham Forstal (2 miles south-east) and Lenham Heath (2 miles south-east). Further out, we also cover Maidstone (8 miles west), Ashford (9 miles south-east), Sittingbourne (7 miles north), Faversham (9 miles north-east), Minster (13 miles north) and Kings Hill (13 miles west).
What’s near Lenham
Typical jobs here are in premises near Kiln Wood, The Red Lion pub and The Lenham School, among other places. There’s a railway station in Lenham itself: Lenham station. A little further out are Coldbridge Castle (2.7 miles south) and The Dog Collar Museum (3.6 miles west).
For landlords and multi-site operators
We also work for facilities teams across offices, schools and healthcare in Lenham and across Kent. Larger estates can be phased building by building around the people who use them.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we are happy to quote for all of it.

How the visit works
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Before we leave, the area is tidied and the paperwork follows. Everything the job in Lenham needs is worked out beforehand, from the survey.
- We survey the unit from photos or on site and agree what’s included.
- We arrange the shutdown with your staff and sheet the area.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- We clean out the drain tray and make sure it drains.
- We close up the unit and send the certificate and before and after photos.
Preparing for the visit
- Tell us where we can park and unload
- Let us know when the site is closed or quiet
- Clear loose items from the work area

Related advice
Between visits
Aftercare is simple, and it makes the next visit easier:
- Make sure the unit’s access doors open easily
- Change filters on schedule and log each change
- Report water on the plant room floor
- Keep the certificate and photo report with the plant records
Restart the unit with your site team or maintenance contractor once we have finished. Check the drain tray is emptying over the first few days to make sure it stays clear.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.
When something else is needed
Some problems need a different service or another trade:
- Building management system faults
- The supply and extract ducts, quoted separately
- Airflow problems caused by the system’s design
