Multi-site and managed buildings
Multi-site operators often want one contractor and one number. We work across London and the South East, so a run of sites can go into one programme and kept to a regular schedule.
When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party and send the paperwork to whoever needs it.
About our AHU cleaning in Mildmay
A cooling coil drips condensate into a tray that should drain away. If the outlet blocks, standing water and slime build up, in the airstream that feeds the building. Clearing and cleaning the tray is central to every AHU clean. The work covers dampers and louvres, drain trays and supply and extract fans, and common reasons people get in touch are plant that has been serviced but not cleaned and fan sections that haven’t been cleaned in years.
London buildings often depend on air handling units in plant rooms or on the roof to supply fresh air. For a building in Mildmay, dust settles in the units and ducts year after year, which is what TR19® Air cleaning deals with.
A written report with pictures follows each visit, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Filters
What’s on the filters is a good clue to what’s further in. They’re photographed before and after for your records.
Fans and fan sections
Before the fan is touched, the unit is shut down and made safe with your site team.
What a clean will not put right
AHU cleaning cannot fix everything, and we will tell you before we start. It doesn’t solve:
- A system that’s undersized for the building
- Mechanical faults with motors, belts or bearings
- Ductwork downstream of the unit, which is a separate clean
Not sure which it is? You can call us on 0345 646 2711 or drop us a line and we will tell you honestly before you book.

Common questions in Mildmay
How do you handle parking and loading in Mildmay?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Much of our London work is done overnight, which helps.
Can you clean school ventilation in Mildmay during the holidays?
Yes, and it’s the easiest time to do it. Around Mildmay, the Food Standards Agency lists about 39 schools and colleges with registered kitchens within a mile and a half or so. You can call 0345 646 2711 or send us an email with the dates the site is empty.
Do you cover Mildmay?
Yes. Mildmay is part of the area we cover, within the South East and London area we cover.
What do you do to protect the area?
Floors and surfaces near the work are sheeted before work begins, and waste is contained as we go. At the end, the area is cleaned down.
What’s TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping and expects a risk-based approach.
Which sectors do you work in?
Any site with a kitchen or a ventilation system to look after, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
Do you give a certificate after the clean?
Yes, a TR19® certificate and a photo report. It includes a recommended date for the next check.
When should our AHU next be cleaned?
It depends on the unit, the filters and how the building is used. Inspection tells you when cleaning is needed, and we’ll suggest an interval after the first clean.
How it works
We start by comparing what we find with the survey or your pictures. Anything unexpected is raised with you before we go further. After that, the work takes one overnight shift for many single units, with bigger plant phased. Managed blocks in London often need contractors booked in ahead, and we are happy to deal with the agent directly for a site in Mildmay.
- We survey the unit from photos or on site and agree what’s included.
- The unit is shut down with your site team and the area protected.
- 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.
- A TR19® certificate and photo report follow the clean.
Getting ready for the visit
- Move anything stored near the system
- Have your last certificate or report to hand
- Let us know about permits to work or site inductions
Ask for a quote
Every quote begins with a look at the system, either from photos and details you send or from a site visit. After that, you get a fixed price for the work so you know the cost before any work starts.
Advice
What affects the cost of AHU cleaning
The diagnosis comes before the price. The main factors are:
- Parking and loading at the site
- Whether it’s a one-off visit or part of a schedule
- Whether several sites go on one quote
- When the work can happen, such as evenings, overnight or weekends
Putting the work off seldom saves money. Problems in a system tend to grow, and a neglected system can mean more work. If you’re unsure, phone us on 0345 646 2711, or email photos and we will give you an honest view and a fixed quote.
What to send for a quote
When you contact us, these details help:
- The paperwork from the last visit, if you have it
- Photos showing the whole system and its surroundings
- Your opening hours and when the area is out of use
- Where the plant sits or the system leaves the building, such as a roof or outside wall
If you need AHU cleaning in Mildmay, give us a ring on 0345 646 2711, or send details by email. Let us know the site type and the opening hours, plus pictures or the previous report if they’re to hand. We usually send a fixed quote within one working day.
What happens if it’s left?
Leave an AHU uncleaned and the dirt does not stay put. It moves on into the ductwork and out into the rooms, so cleaning the ducts without the unit only goes so far. Leaving it on a busy London site only adds to the work.
Working hours, access and the scale of the site all affect the cost. We take each of them into account, and the price is fixed before work begins.

Do you need AHU cleaning in Mildmay?
Filters that are not changed or cleaned on time clog up, which cuts the airflow and can let air slip round the filter. After that, the coils and fan collect what the filter should have caught.
Signs it’s time to call us include:
- Condensate trays that won’t empty
- Stale or musty smells from the ventilation
- Air handling units due a clean after building work
- Intake sections clogged with outdoor debris
For workplaces around Dalston Kingsland station with mechanical ventilation, cleaning can be done in the evening or at weekends.
