About our AHU cleaning in Enfield Lock
Our AHU cleaning covers sites in Enfield Lock and the rest of Greater London, in buildings such as offices, schools, healthcare sites and shops. The work is timed around when the system can be switched off, including evenings, nights and weekends. Typical jobs include fan sections that haven’t been cleaned in years and stale or musty smells from the ventilation, across heating and cooling coils, supply and extract fans and filter sections.
In London, plant rooms are often in basements or on roofs reached through occupied floors, so work in Enfield Lock is often done in the evening or at weekends. Parking and loading are agreed with the building in advance.
Think of the report as the system’s health record: dated, with pictures, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

Staff cleaning versus specialist work
When your team notices a problem 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.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Different parts, different methods
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. Anything like that is recorded with photos.
Filters
Filters are the first line of defence in the unit. We check them, and clean or change them as agreed in the quote, and clean the filter housing.
How the visit works
The visit has three parts: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with pictures. Most of the time goes on the work itself, and that takes half a day to a full day per unit, with large plant planned over several shifts. Expect the work in Enfield Lock to happen after your last customer leaves, not during trading.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before pictures of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- We take after photos and issue the certificate and report.
Getting ready for the visit
- Make sure equipment near the work can be switched off and left to cool
- Agree a time when the area can be out of use
- Dig out any earlier paperwork for the system
Getting a quote
Quoting starts with a diagnosis, from your photos and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work so you know the cost before we start.

Aftercare tips
No system stays clean for ever, but care slows the build-up. Our tips:
- Look at the condensate drain whenever the unit is serviced
- Report stiff or damaged access doors
- Clear leaves and litter away from the intake
- Plan the next inspection before the last report gets filed away
Keep filter changes on schedule between cleans, as that does more than anything to keep the unit clean. Record each change in the maintenance log.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.
Enfield Lock: your questions answered
Can you clean school ventilation in Enfield Lock during the holidays?
Yes. Half-terms and the summer break are the natural time for school work. With about 28 schools and colleges on the FSA’s register within roughly a mile and a half of Enfield Lock, it pays to plan holiday dates ahead. Booking early in the term gives the best choice of holiday dates.
Can you work in Enfield Lock outside opening hours?
Yes, evening, overnight and weekend work is normal for us. It means the site in Enfield Lock keeps running as normal. Tell us your opening hours when you ask for a quote.
How much does AHU cleaning cost?
Size, condition, access and working hours all affect the cost. Call for a fixed quote, normally ready within one working day.
Do you offer maintenance contracts?
Yes, of course. Tell us what you have and how it’s used, and we will suggest a schedule and quote for it.
How much notice do you need?
Book as early as you can for planned work, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.
What about areas you can’t get to?
They’re listed in the report, never skipped quietly. You will know exactly which parts weren’t reached and why, along with a quote to put access in.
Will the ventilation be off while you clean?
Yes. The unit has to be shut down and isolated before it’s opened. The shutdown is planned with whoever runs the building.
What do you do with what you remove?
It leaves the site with us at the end of the visit. While we work, it’s kept contained to keep the area clean.
What a clean will not put right
We will not sell you work that doesn’t address the problem, so these are the things it won’t cover:
- Faulty motors, drives or bearings
- Ventilation that was badly designed in the first place
- Building management system faults
If in doubt, call us on 0345 646 2711 or email us and we’ll say what we think.

What else we do in Enfield Lock
Signs you need AHU cleaning in Enfield Lock
Filters that aren’t changed or cleaned on time clog up, cutting airflow and sometimes letting dirty air bypass them altogether. After that, the coils and fan collect what the filter should have caught.
What we are most often called out for:
- Fan sections that haven’t been cleaned in years
- Plant that needs cleaning after a refit
- Leaves and litter drawn into the unit
- Dirty coils holding back the airflow
If you manage a school such as Prince of Wales Primary School, ventilation cleaning is best booked for the holidays.

Why it’s worth doing now in Enfield Lock
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.
What you pay depends on how big the system is, what state it’s in and how easy it is to reach. We give you a fixed price before work begins, so you know where you stand.
Why us?
- A written report with pictures after each visit
- Trading since 2009
