AHU cleaning for kitchens and businesses in Thamesmead
Heating and cooling coils trap dust that gets past the filters. Dirt on the fins holds back air and makes the unit work harder to do the same job. Coils are cleaned carefully, with methods chosen so the fins aren’t flattened. Typical jobs include debris and leaves in the fresh air intake and units needing a clean before a new tenant or handover, across supply and extract fans, drain trays and heating and cooling coils.
Across London, offices, hotels, schools and healthcare buildings rely on mechanical ventilation, much of it supplied through air handling units on roofs or in basements. For a building in Thamesmead, dust settles in the units and ducts year after year, which is what TR19® Air cleaning deals with.
The sign-off is always in writing: a dated report with photos of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

What affects the quote in Thamesmead
You will get a fixed price before work begins. It takes into account:
- Any permits to work or inductions
- Travel, parking and unloading
- How easy every part is to reach
- The condition we find in the survey
A single site or a whole portfolio, the quote is built the same way: what needs doing, how we get to it and when. The price is fixed before any work starts.
Asking for a quote
You don’t need the technical terms. It helps if you can send:
- Your last certificate, test record or report
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Detail shots of panels, filters and grilles
- Photos showing the whole system and its surroundings
For AHU cleaning in Thamesmead, call 0345 646 2711 or drop us a line. Let us know the site type and the opening hours, plus photos or the previous report if they’re to hand. A fixed quote normally follows within one working day.

Staff cleaning versus specialist work
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We will take a look and send you a fixed quote.
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.
When it’s something else
In fairness, there are a few things this work will not fix:
- Building management system faults
- Ventilation that was badly designed in the first place
- Dirty ducts beyond the unit itself
If in doubt, call us on 0345 646 2711, or email photos and we will say what we think.

Signs you need AHU cleaning in Thamesmead
Planned maintenance often covers belts, motors and filters but not cleaning. That means a unit can tick every service box and still be carrying years of dirt.
It’s time to book a visit if you see:
- Air handling units due a clean after building work
- Fan sections that haven’t been cleaned in years
- Condensate trays that won’t empty
- Leaves and litter drawn into the unit
For schools like Jubilee Primary School, the holidays are the usual time to inspect and clean ventilation.

Common questions in Thamesmead
How do you handle parking and loading in Thamesmead?
A loading bay, a visitor permit or off-street space near the site in Thamesmead makes the visit easier to plan. Night visits tend to make loading easier on London streets.
Do you do school ventilation cleaning in Thamesmead in the summer holidays?
Yes, out-of-term visits are normal for schools. Around Thamesmead, the Food Standards Agency lists about 29 schools and colleges with registered kitchens within a mile and a half or so. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Do you offer maintenance contracts?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, to suit the system and how it’s used.
Where does the waste go?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. We do not leave it behind.
Do you need to switch the unit off?
Yes. Cleaning needs the unit off and isolated, so we plan it for a time that suits the building.
Do you work in Thamesmead?
Yes. Thamesmead is part of the area we cover, within the South East and London area we cover.
Do you look at the system first?
Yes. For many sites, photos and a few details are enough, and larger or hidden systems get a visit.
What’s TR19?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Ventilation in Thamesmead buildings
There are about 29 schools, colleges and universities and about 30 care, childcare and hospital premises on the FSA’s food hygiene register across Thamesmead and its immediate surroundings (about a mile and a half). Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Thamesmead’s nearest hospital, Erith and District Hospital, is about 2.6 miles south-east. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital. London plant rooms are often on roofs or in basements reached through occupied floors.
Hospitals such as Erith and District Hospital (about 2.6 miles south-east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Thamesmead are no different.

How it works
The first job on site is protection: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. It takes one overnight shift for many single units, with bigger plant phased, and we clear up before we go. Security desks and permits-to-work are routine in London, so let us know what your building in Thamesmead needs from us.
- First the unit is surveyed, from pictures or a visit, and the scope agreed.
- The unit is shut down with your site team and the area protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- We clean out the drain tray and make sure it drains.
- You get a TR19® certificate and a photo report.
Preparing for the visit
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Arrange a key holder or contact on site
- Let us know about parking and loading
Ask for a quote
Getting a quote does not take long. Send a few details and photos, and we usually reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.

Managing agents and facilities teams in Thamesmead
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We are happy to deal with either side, and the report can go to both.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
Why it’s worth doing now in Thamesmead
If people in a building in Thamesmead complain about stuffy or smelly air, the AHU is worth looking at. Cleaning it deals with the cause rather than the symptom. London sites work long hours, and the longer a job is left, the bigger it gets.
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll go through it with you.
