Common questions in Northumberland Park
Do you work overnight in Northumberland Park?
Yes, we can come after you close and finish before you open. That way a site in Northumberland Park does not have to lose a day’s trading. When you give us a ring on 0345 646 2711 or drop us a line, mention when the site is quiet.
Can parking be tricky for a job in Northumberland Park?
London parking can be tight, so details of loading bays and permits help. Where restrictions apply in the day, an evening or overnight visit usually gets round them.
Do you offer emergency callouts?
Yes, 24/7. Our office is open from 8am to 6pm on weekdays, with the emergency line covering every other hour.
Is there a survey before the work?
Yes. We always survey first, from your photos and details, or with a visit where necessary. Then you get a fixed quote.
Can you look after several sites?
Yes. Send the list of sites and the work at each and we will quote them together.
How far ahead should we book?
The more notice, the better, especially for out-of-hours work. We normally quote within one working day, and there’s a 24/7 line for emergencies.
What types of premises do you cover?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, as well as food production and leisure sites.
What happens if you can’t reach some of it?
We never leave them off the paperwork. The report says which parts couldn’t be reached and why, and we can quote to improve the access.
AHU cleaning in Northumberland Park, done properly
All the building’s air passes through the fan, so dirt on the impeller and housing gets spread around. Fan, housing and the surrounding panels are cleaned as part of the job, once the unit has been shut down and isolated. The work covers supply and extract fans, drain trays and internal panels, and common reasons people get in touch are drain trays holding standing water and dust-coated heating and cooling coils.
London buildings often depend on air handling units in plant rooms or on the roof to supply fresh air. For a building in Northumberland Park, dust settles in the units and ducts year after year.
Accreditations are easy to claim and worth checking. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

When to call us in Northumberland Park
Most units live out of sight on roofs, in plant rooms or in ceiling voids, so they’re easy to forget about. Months can pass without anyone looking inside.
Look out for any of the following:
- Coils clogged with dust and debris
- Air handling units due a clean after building work
- Intake sections clogged with outdoor debris
- Plant that has been serviced but not cleaned
Workplaces around Northumberland Park (London) station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts.
Before you book anyone
- Proof of accreditation you can verify
- Whether the work can be done while the site is closed
- Whether a written report and pictures are included
- If they look at the system before pricing
What happens if it’s left?
Stuffy rooms and stale smells in a building in Northumberland Park can sometimes be traced back to the AHU. A clean tackles the source instead of masking it. London sites work long hours, and the longer a job is left, the bigger it gets.
Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered, and you will get one fixed quote.

What staff can safely do
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.
Honest limits
To be straight with you, some problems need a different fix:
- Ductwork downstream of the unit, which is a separate clean
- Coils that are corroded or leaking and need replacing
- Airflow problems caused by the system’s design
If you are not sure, just give us a ring on 0345 646 2711, or send details by email and we will give you a straight answer before booking.
Parts of the system we cover
- Heating and cooling coils
- Drain trays
- Filter sections
- Dampers and louvres
- Supply and extract fans
- Internal panels
Northumberland Park buildings and their air
The FSA’s food hygiene register lists about 41 schools, colleges and universities, about 32 hospitals, care homes and childcare premises and about 3 hotels and guest houses with registered kitchens or food service within about 1.5 miles of central Northumberland Park. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Northumberland Park’s nearest hospital, North Middlesex University Hospital, is about 0.9 miles north-west. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale. Many London buildings have had their ductwork altered through several fit-outs, so an inspection comes first.
Healthcare ventilation, from large hospitals like North Middlesex University Hospital (about 0.9 miles north-west) to small clinics, depends on clean filters, coils and ducts. If you manage a school such as Lea Valley Primary School, ventilation cleaning is best booked for the holidays.

How it works
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool first, and floors and nearby surfaces are sheeted. The work itself takes a single shift for a typical unit, longer for large or heavily soiled ones. We fit London jobs around the building rather than the other way round, so a visit in Northumberland Park is typically out of hours.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Preparing for the visit
- Tell us about site rules, permits or sign-in
- Mention any locked doors, roof access or ceiling voids
- Let us know about parking and loading

What else we do in Northumberland Park
How we price AHU cleaning
The diagnosis comes before the price. The main factors are:
- Access, including roofs, risers and ceiling voids
- The number of sites or systems
- Whether it’s a one-off visit or part of a schedule
- When the work can happen, such as evenings, overnight or weekends
A single site or a whole portfolio, we price it on the same basis: the work involved, the access and the timing. The price is fixed before work begins.
Asking for a quote
Photos and a few facts are often enough to price the work. Send what you can of the following:
- The paperwork from the last visit, if you have it
- How we’d reach plant on a roof or in a plant room
- Problems your staff have spotted
- Your opening hours and when the area is out of use
We do not publish a price list, because every site is different. We look at your system first, from pictures or on a visit, and then send you a fixed quote. To start, give us a ring on 0345 646 2711, or send details by email.
Looking after it afterwards
Here’s the after-treatment advice, short and simple:
- Report water on the plant room floor
- Flag stale or damp smells in the supply air
- Don’t store bins or materials near 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. A drain that’s cleared early never gets to the slime stage.
