Common questions in Woodside Park
Can ventilation in schools around Woodside Park be cleaned out of term?
Yes, and it’s the easiest time to do it. There are about 30 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Woodside Park. You can phone us on 0345 646 2711 or drop us a line with the dates the site is empty.
Can you come to Woodside Park after we close?
Yes, nights and weekends are routine for us. Your customers, staff or residents in Woodside Park needn’t be disturbed. Let us know the hours you’re closed and we’ll book within them.
Is there a report after cleaning?
Yes. You get a TR19® certificate plus before and after pictures. Keep them in the maintenance log.
How far ahead should we book?
Earlier is better, especially for out-of-hours work. Quotes normally come back within one working day, and there’s a 24/7 line for emergencies.
What about areas you can’t get to?
We record them on the report, with photos where possible, and we explain what access is needed, such as extra access panels in ductwork.
Which sectors do you work in?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, as well as food production and leisure sites.
What does TR19 mean?
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.
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.
How we handle AHU cleaning in Woodside Park
Units vary a lot in size, age and layout, whether it’s a compact unit in a ceiling void or a big unit on the roof. Every job starts with a survey, from photos or on site, followed by a fixed quote before any cleaning starts. If you have dirty fans and fan housings and air handling units with blocked filters, we can put it right.
In London, plant rooms are often in basements or on roofs reached through occupied floors, so work in Woodside Park is often done in the evening or at weekends. Parking and loading are agreed with the building in advance.
Good records are part of the job. Each visit is written up with photos, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

AHU cleaning around Woodside Park
The FSA’s food hygiene register lists about 30 schools, colleges and universities and about 50 care, childcare and hospital premises with registered kitchens or food service in Woodside Park and the streets around it, up to about 1.5 miles out. Busy, occupied buildings like these are where clean supply air matters most. Getting kit to a London plant room usually means lifts, stairs and an agreed loading slot. For Woodside Park, the closest hospital is Finchley Memorial Hospital, roughly 0.9 miles south-east. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.
For schools like Northside Primary School, the holidays are the usual time to inspect and clean ventilation.

How we price AHU cleaning
Before we fix a price, we need to know a few things. We look at:
- The size of the system
- What state the system is in
- A single visit or a regular plan
- Any permits to work or inductions
Several systems or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at and we will price it together.
What to send for a quote
You don’t need the technical terms. Just send:
- Any symptoms, from odd noises to smells or leaks
- The postcode and the type of business
- When the site is open and when it’s quiet
- Where the plant sits or the system leaves the building, such as a roof or outside wall
For a fixed quote, call us on 0345 646 2711 or send us an email with the site type, your trading hours and a short description of the system. A few pictures and your last certificate or report help a lot. We usually come back within one working day.
Why it’s worth doing now in Woodside Park
A light clean now is simpler than a heavy one later. Years of build-up make the job longer and harder, especially where there’s been moisture. It’s better booked as a planned job in Woodside Park than handled as an emergency.
Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you’re unsure, call us on 0345 646 2711, or send details by email and we’ll give you an honest view and a fixed quote.

When to call us in Woodside Park
Dirt in an AHU matters in two ways: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For the people using the building every day, that is the air they breathe for hours on end.
Most sites get in touch when they notice one of these:
- Units needing a clean before a new tenant or handover
- Drain trays holding standing water
- Air handling units with blocked filters
- Units that have only ever had filter changes
Hospitals such as Finchley Memorial Hospital (about 0.9 miles south-east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Woodside Park are no different.
Questions to ask before you book
- Proof of insurance
- How VAT is shown on the quote
- What records you’ll receive afterwards
- How areas they can’t reach will be recorded
What your team can do, and what needs us
If your staff spot something 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 send you a fixed quote.
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
The process
The visit has three parts: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with photos. The middle part takes longest, and that takes a single shift for a typical unit, longer for large or heavily soiled ones. Loading bays, visitor permits and roof access are the first things we ask about for a site in Woodside Park.
- We survey the unit from pictures or on site and agree what’s included.
- We arrange the shutdown with your staff and sheet the area.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Standing water and slime come out of the tray and the drain is checked.
- You get a TR19® certificate and a photo report.
Getting ready for the visit
- Dig out any earlier paperwork for the system
- Make sure equipment near the work can be switched off and left to cool
- Clear loose items from the work area
How to get a quote
There’s no standard price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, and then send you a fixed quote. To start, call 0345 646 2711, or send details by email.
Advice
Multi-site and managed buildings
Keeping records across a portfolio is half the battle. Each visit produces a dated report with pictures, ready to show insurers, fire officers or EHOs.
Multi-site operators often want one contractor and one number. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.
What the work involves, part by part
Drain trays
The drain tray collects water from the cooling coil. We clear standing water, clean out slime and check the outlet is draining.
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. Anything like that is recorded with pictures.
