Romford AHU cleaning
Cleaning of air handling units, including filters, coils, drain trays, fans and internal surfaces for commercial sites in Romford and across Greater London. BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease.
- Dust-coated heating and cooling coils
- Plant that needs cleaning after a refit
- Leaves and litter drawn into the unit
Leave it or put it right?
A clogged coil or dirty fan makes the unit work harder for the same airflow. The result is extra wear and a building that doesn’t feel as comfortable, and a planned clean is far less disruptive than a breakdown. Leaving it on a busy London site only adds to the work.
Kitchens, offices, schools and hospitals are all priced 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 will go through it with you.

AHU cleaning for kitchens and businesses in Romford
Our AHU cleans for sites in Romford cover the parts that collect dirt: 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 fan sections that haven’t been cleaned in years and plant that needs cleaning after a refit, we can help, from dampers and louvres, internal panels and supply and extract fans onwards.
London offices and flats often have ductwork added through successive refits, with old runs left behind that are hard to reach. In Romford, as elsewhere, cleaning starts with an inspection of what’s there.
A written report with photos follows every 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.

What we’re called out for in Romford
Most units live out of sight on roofs, in plant rooms or in ceiling voids and are rarely seen by anyone but maintenance staff. It’s easy for a long time to go by without anyone opening the panels.
The symptoms we are asked about most are:
- Odours coming through the supply air
- Debris and leaves in the fresh air intake
- Air handling units never cleaned inside
- Blocked condensate drains and slimy trays
School buildings such as Concordia Academy are normally done in the holidays, so classrooms aren’t disturbed.
Questions to ask before you book
- What’s included in the scope, part by part
- When they can work, and whether that’s outside your opening hours
- How they set the interval to the next visit
- How VAT is shown on the quote
Aftercare tips
How long the results last depends on use and care. We suggest:
- Change filters on schedule and log each change
- Keep the area around the fresh air intake clear
- Make sure the unit’s access doors open easily
- Report musty smells from the vents right away
You receive a TR19® certificate and a photo report after the clean. Keep both with the building’s maintenance records.
Make sure access doors and panels on the unit open easily. Sections that are awkward to open are the ones that get skipped.

FAQs for Romford
Can the work in Romford be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Romford needn’t be disturbed. Tell us your opening hours when you ask for a quote.
Do you do school ventilation cleaning in Romford in the summer holidays?
Yes. Half-terms and the summer break are the natural time for school work. Around Romford, 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 will book the visit for when the site is empty.
Do you cover Romford?
Yes. Romford is part of the area we cover, as part of our area across London and the South East.
What do you need from me for a quote?
A short description and a few pictures plus the address and your hours. If we need more, we will ask.
Where does the waste go?
Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. We do not leave it behind.
What is TR19?
TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Which kinds of sites do you work on?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.
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.
Part by part
Drain trays
Drain trays can rust and leak over time. Their condition goes into the report with photos so repairs can be planned.
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. We clean them with care so the fins are not damaged.
When something else is needed
A few issues sit outside what this work can do:
- Ventilation that was badly designed in the first place
- Faulty motors, drives or bearings
- Coils that are corroded or leaking and need replacing
Not sure which it is? You can give us a ring on 0345 646 2711 or send us an email and we will tell you honestly.

Romford buildings and their air
Food Standards Agency records list about 29 schools, colleges and universities, about 69 care, childcare and hospital premises and about 7 hotels and guest houses registered as food businesses within about 1.5 miles of central Romford. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. About less than half a mile south of Romford is Oldchurch Hospital, the nearest hospital. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients. Getting kit to a London plant room normally means lifts, stairs and an agreed loading slot.
Healthcare buildings such as Oldchurch Hospital, about under half a mile south, depend on their ventilation; if you manage a surgery, clinic or care home near Romford, yours matters too. Workplaces around Romford station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts.

In-house cleaning or a specialist?
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We’ll take a look and send you a fixed quote.
How it 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 the rest is down to us. Before we leave, the area is tidied and the paperwork follows. In Romford, as across London, we typically work overnight or at weekends and hand the site back ready to open.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before pictures of each section of the unit.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- After photos are taken and the certificate issued.
Before we arrive
- Let us know how we reach the system, including roofs, risers and plant rooms
- Dig out any earlier paperwork for the system
- Clear the space around the work
How to get a quote
We do not publish a price list, because no two systems are the same. We look at your system first, from photos or on a visit, then send a fixed quote. To start, call 0345 646 2711 or email us.
