Greater London · Air handling unit cleaning
Air handling unit cleaning in Park Royal, Greater London
We cover Park Royal for AHU cleaning. Out-of-hours visits, a fixed quote and a written report with pictures on every job.
- Units that have only ever had filter changes
- Dirty coils holding back the airflow
- Dirty fans and fan housings
Keeping the system healthy
After the visit, a few habits help the work last:
- File each AHU report in the maintenance log
- Note any water around the unit or leaks below it
- Change filters on schedule and log each change
- Book the next check in line with the report
If the ductwork hasn’t been cleaned, consider it next. Cleaning the unit and ducts together gives the best result, and we can survey both.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
AHU cleaning in Park Royal
An air handling unit is the heart of a building’s ventilation: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Whatever builds up inside it travels with that air, so cleaning the unit matters as much as cleaning the ducts. If you have leaves and litter drawn into the unit and condensate trays that won’t empty, we can help, from supply and extract fans, drain trays and filter sections onwards.
In London, plant rooms are often in basements or on roofs reached through occupied floors, so work in Park Royal is often done in the evening or at weekends. Parking and loading are agreed with the building in advance.
For insurers and inspectors, the record counts. That is why every job is written up in a report with photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Multi-site and managed buildings
Records are where multi-site compliance often slips. Each visit produces a dated report with photos, ready to show insurers, fire officers or EHOs.
Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept on a regular cycle.
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 pictures. The middle part takes longest, and that takes one overnight shift for many single units, with bigger plant phased. We fit London jobs around the building rather than the other way round, so a visit in Park Royal is typically out of hours.
- First the unit is surveyed, from pictures or a visit, and the scope agreed.
- 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.
- We clean out the drain tray and make sure it drains.
- You get a TR19® certificate and a photo report.
Before we arrive
- Mention any parking or loading restrictions
- Have your last certificate or report to hand
- Arrange a key holder or contact on site
Get a fixed quote
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before work begins.

How we price AHU cleaning
The survey tells us what the work involves. We look at:
- The condition of the system
- Site requirements such as sign-in and permits
- The number of sites or systems
- One-off work versus a regular cycle
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you are not sure what’s needed, give us a ring on 0345 646 2711 or use the quote form for straight advice and a fixed quote.
What to send for a quote
A few details help us quote accurately. When you get in touch, it helps to send:
- Problems your staff have spotted
- When the site is open and when it’s quiet
- Detail shots of panels, filters and grilles
- Your last certificate, test record or report
Quoting starts with a diagnosis, from your pictures and details or, where that is not enough, a survey on site. Then we send a fixed price, before we start.
Park Royal: your questions answered
Can ventilation in schools around Park Royal be cleaned out of term?
Yes. Half-terms and the summer break are the natural time for school work. With about 38 schools and colleges on the FSA’s register within roughly a mile and a half of Park Royal, it pays to plan holiday dates ahead. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Can you work in Park Royal outside opening hours?
Yes, nights and weekends are routine for us. Your customers, staff or residents in Park Royal needn’t be disturbed. When you ring 0345 646 2711 or send us an email, mention when the site is quiet.
What should I send you?
The site address, the type of premises and your opening hours, plus pictures of the system and your last certificate or report if you have one.
How do you protect the area?
By covering it before any work starts. The work is kept contained and leave the area clean.
Can you set up regular visits?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, depending on what the system needs.
How much notice do you need?
The more notice, the better, particularly for night and weekend visits. Quotes normally come back within one working day, and there’s a 24/7 line for emergencies.
Is Park Royal in your area?
Yes. Park Royal is part of the area we cover, within the South East and London area we cover.
How often do AHUs need cleaning?
That’s set by inspection, in line with TR19® Air. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.

Do you need AHU cleaning in Park Royal?
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.
Clients usually contact us when they notice one of these:
- Odours coming through the supply air
- Condensate trays that will not empty
- Intake sections clogged with outdoor debris
- Air handling units due a clean after building work
Wherever a school like West Twyford Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.
What to look for in a quote
- Whether VAT is included
- Whether the work can be done while the site is closed
- What’s included in the scope, part by part
- Whether a written report and photos are included

About under half a mile north-east of Park Royal is Central Middlesex Hospital, the nearest hospital.

What your team can do, and what needs us
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
What the work involves, part by part
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. We clean the coil and the tray beneath it together.
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. We clean each section from intake to discharge.
