Plashet: your questions answered
Does London parking affect a job in Plashet?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Much of our London work is done overnight, which helps.
Can a school’s ventilation in Plashet be done out of term time?
Yes. The holidays are the usual time for school work. Around Plashet, the Food Standards Agency lists about 55 schools and colleges with registered kitchens within a mile and a half or so. Send us your term dates when you call us on 0345 646 2711 or send us an email, and we’ll fit the work in.
What do you do to protect the area?
We cover floors and nearby surfaces with sheeting before we start, and waste is contained as we go. Before we leave, we tidy up and clean 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.
Does the AHU have to be shut down for cleaning?
Yes. Cleaning needs the unit off and isolated, so we plan it for a time that suits the building.
How long does it take to clean an air handling unit?
Typically the clean takes from a few hours for a compact unit to a day or more for a large one. We plan the shutdown around that, out of hours if needed.
How much does AHU cleaning cost in Plashet?
We don’t publish prices, because the cost depends on the job: the size of the system, its condition, access and when we can work. You get a fixed price before any work starts.
Which sectors do you work in?
All kinds of commercial and public premises: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. We fit the work around how the site operates.
AHU cleaning for kitchens and businesses in Plashet
An air handling unit is the heart of a building’s ventilation: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Whatever builds up inside it travels with that air, so cleaning the unit matters as much as cleaning the ducts. If you have leaves and litter drawn into the unit and coils clogged with dust and debris, we can put it right.
London buildings tend to keep their plant on the roof or below ground, so work in Plashet is often done in the evening or at weekends. Loading and parking are planned with the building first.
For insurers and inspectors, the record counts. So every job comes with a written report and pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Staff cleaning versus specialist work
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.
Common problems we fix in Plashet
Mechanical servicing keeps a unit running, but it does not always include cleaning the inside. So a unit can be well maintained and still dirty.
The symptoms we are asked about most are:
- Intake sections clogged with outdoor debris
- Dust-coated heating and cooling coils
- Rooms that smell stuffy when the system runs
- Dirty fans and fan housings
Healthcare buildings such as Newham University Hospital, about 1.5 miles south, depend on their ventilation; if you manage a surgery, clinic or care home near Plashet, yours matters too.
Before booking anyone
- When they can work, and whether that’s outside your opening hours
- Whether the quote shows VAT
- When the next visit should be, and why
- Whether the price is fixed
What we do, step by step
We are used to working while the site is closed. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. The visit itself takes half a day to a full day per unit, with large plant planned over several shifts. A name and number for whoever controls access to the building in Plashet saves time on the night.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- 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.
- Drain trays are cleared and cleaned and the outlet checked.
- You get a TR19® certificate and a photo report.
Preparing for the visit
- Clear the space around the work
- Tell us where we can park and unload
- Mention any sign-in, permit or induction we need
How to get a quote
The quickest way to a quote is to send pictures: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.

Fans and fan sections
Build-up on fan blades can upset the balance and add wear. A clean fan runs more smoothly.
Drain trays
Standing water in a tray sits right where the air passes. We clean it and note if the slope or the drain needs attention.
Ventilation in Plashet buildings
The FSA’s food hygiene register lists about 55 schools, colleges and universities, about 59 caring premises (care homes, nurseries and hospitals) and about 15 hotels and B&Bs with registered kitchens or food service within roughly a mile and a half of the centre of Plashet. Busy, occupied buildings like these are where clean supply air matters most. London plant rooms are often on roofs or in basements reached through occupied floors. Plashet’s nearest hospital, Newham University Hospital, is about 1.5 miles south. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.
Workplaces around Woodgrange Park station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts. If you manage a school such as Plashet School, ventilation cleaning is best booked for the holidays.

Looking after it afterwards
Good habits slow the build-up between visits. A few tips:
- Report water on the plant room floor
- Plan the next inspection before the last report gets filed away
- File each AHU report in the maintenance log
- Make sure the unit’s access doors open easily
Keep filter changes on schedule between cleans, because good filters protect everything downstream. Record each change in the maintenance log.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
What a clean will not put right
An honest diagnosis matters more to us than a booking, so here’s what this work can’t put right:
- Controls and BMS settings that run the unit
- The supply and extract ducts, quoted separately
- A system that’s undersized for the building
If in doubt, call us on 0345 646 2711 or use the quote form and we’ll say what we think before you book.
Parts of the system we cover
- Filter sections
- Internal panels
- Heating and cooling coils
