Kew: your questions answered
What do you need to know about parking in Kew?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Much of our London work is done overnight, which helps.
Do you work overnight in Kew?
Yes, we can come after you close and finish before you open. The work in Kew can fit around your hours. Let us know the hours you’re closed and we will book within them.
When should our AHU next be cleaned?
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.
How do you protect the area?
Protection goes down first: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.
Will the ventilation be off while you clean?
Yes. The unit has to be shut down and isolated before it’s opened. We agree the timing with your site team.
Is there a report after cleaning?
Yes. You get a TR19® certificate plus before and after photos. They’re worth keeping with the plant records.
Which kinds of sites do you work on?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.
What happens to the waste?
We contain it and take it with us. We collect grease, debris and waste water as we go rather than letting it spread.
AHU cleaning in Kew, done properly
Our AHU cleaning covers sites in Kew and the rest of Greater London, in offices, schools, hospitals, care homes and retail. Units are cleaned when the site can spare them, often evenings, overnight or weekends. Typical jobs include stale or musty smells from the ventilation and dirty fans and fan housings, across internal panels, filter sections and dampers and louvres.
Across London, offices, hotels, schools and healthcare buildings rely on mechanical ventilation, much of it supplied through air handling units on roofs or in basements. In a building in Kew, dust and debris build up in the units and ductwork over time, which is what TR19® Air cleaning deals with.
Good records are part of the job. You get a written report with photos after every visit, 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.

What else we do in Kew
Ventilation in Kew buildings
The FSA’s food hygiene register lists about 33 schools, colleges and universities, about 48 care, childcare and hospital premises and about 10 hotels and B&Bs with registered kitchens or food service across Kew and its immediate surroundings (about a mile and a half). Buildings like these often rely on mechanical ventilation, which TR19® Air covers. Getting kit to a London plant room usually means lifts, stairs and an agreed loading slot. For Kew, the closest hospital is Barnes Hospital, roughly 1.5 miles south-east. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.
If you manage offices or shops near Chiswick station, their ventilation can be inspected and cleaned out of hours. Healthcare ventilation, from large hospitals like Barnes Hospital (about 1.5 miles south-east) to small clinics, depends on clean filters, coils and ducts.
Kew is about 2 miles south of Acton, in Greater London. Kew gets the same approach as every site we work on: diagnosis first, a fixed price, out-of-hours working where needed and a written report with photos. 764 places in Greater London are on our list, large and small. Our London page covers sites nearby, about 8 miles away.
Every address in W4, TW9 and TW8 is covered for AHU cleaning, from busy streets to back roads. Streets in the area include Kew Road, Maze Road and Kent Road, and we cover them all for AHU cleaning. Kew is on the A3000, which makes it straightforward for our technicians to reach for AHU cleaning. Other places close to Kew include Strand-on-the-Green (1 mile north), Grove Park (1 mile east), North Sheen (1 mile south), Gunnersbury (1 mile north) and Turnham Green (1 mile east). Further out, we also cover London (8 miles east), City of Westminster (6 miles east), Marylebone (6 miles north-east), Kensington (3 miles east), St Pancras (7 miles north-east) and Shoreditch (9 miles east).

The countryside around Kew includes Kew Gardens Lake and Duke's Hollow.
Multi-site and managed buildings
We also work for facilities teams across offices, schools and healthcare across Greater London. Larger estates can be phased building by building around the people who use them.
We regularly work with managing agents. Tell us the site, the work and the access arrangements and we’ll come back with a fixed quote.
Fixed quotes for AHU cleaning in Kew
Sites vary more than people expect. The main factors:
- One-off work versus a regular cycle
- Any permits to work or inductions
- Whether we need access equipment or extra panels
- How many systems or sites are involved
One small site or a whole estate, the quote is built the same way: what needs doing, how we get to it and when. You’ll have a fixed price before any work starts.
Asking for a quote
There’s no need for technical detail. Just send:
- A few general shots of the system
- Detail shots of panels, filters and grilles
- Problems your staff have spotted
- Where the plant sits or the system leaves the building, such as a roof or outside wall
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.
Leave it or put it right?
Tenants, auditors and owners may want proof that the air handling plant is kept clean. A TR19® certificate and photo report give you that, for audits, tenants or your own peace of mind. Planning ahead in Kew lets you pick a quiet night rather than lose a busy one.
The cost depends on how big the system is, the condition it’s in and access to every part of it. We give you a fixed price before we start, so there are no surprises.
Why book with us
- We are fully insured
- One number for every site across the South East and London

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. That’s our job.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
What the work involves, part by part
Filters
Clogged filters reduce airflow, and dirt can get round the edges. The filter section is cleaned so new or cleaned filters sit properly.
Rooftop and plant room units
Units on roofs and in plant rooms can be awkward to reach. We plan safe access as part of the survey, before we quote.
What we do, step by step
Protection comes first: floors, worktops and anything near the work are covered. Then we make the system safe and start. It takes from a few hours for a compact unit to a day or more for a large one, and we clear up before we go. A name and number for whoever controls access to the building in Kew saves time on the night.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Getting ready for the visit
- Tell us about site rules, permits or sign-in
- Tell us the best time to work, such as after service or at a weekend
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
How to get a quote
Getting a quote doesn’t take long. Send a few details and photos, and we typically reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.

Signs you need AHU cleaning in Kew
Mechanical servicing keeps a unit running, but it doesn’t always include cleaning the inside. That means a unit can tick every service box and still be carrying years of dirt.
Signs it’s time to call us include:
- Leaves and litter drawn into the unit
- Plant that needs cleaning after a refit
- Dirty fans and fan housings
- Odours coming through the supply air
Wherever a school like Grove Park Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.
What your quote should include
- Whether a written report and photos are included
- Whether a survey comes first
- Proof of accreditation you can verify
- When they can work, and whether that’s outside your opening hours
