Why it’s worth doing now in Paddington Green
Dirt left in an air handling unit does not stay in the unit. It moves on into the ductwork and out into the rooms, which is why the unit and the ducts are best cleaned together. Choosing the date yourself beats having a fault choose it for you.
One small site or a whole estate, the quote is built the same way: the work involved, the access and the timing. The price is fixed before we start.

AHU cleaning for kitchens and businesses in Paddington Green
An air handling unit is the heart of a building’s ventilation: air is pulled in, filtered, conditioned and sent out through the ducts. Anything that collects inside the unit can end up in the rooms it serves, so cleaning the unit matters as much as cleaning the ducts. If you’re dealing with stale or musty smells from the ventilation and dust-coated heating and cooling coils, we can help.
London buildings tend to keep their plant on the roof or below ground, so ventilation cleaning in Paddington Green is typically planned out of hours. Loading and parking are planned with the building first.
Think of the report as the system’s health record: dated, with pictures, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

Paddington Green: your questions answered
Can the work in Paddington Green be done at night or at weekends?
Yes. We work evenings, overnight and at weekends. That way a site in Paddington Green doesn’t have to lose a day’s trading. When you give us a ring on 0345 646 2711, or send details by email, mention when the site is quiet.
Does London parking affect a job in Paddington Green?
Tell us where a van can stop near your site in Paddington Green, and about any building rules on loading. Where restrictions apply in the day, an evening or overnight visit usually gets round them.
How long does an AHU clean take?
Typically the clean takes anything from half a day for one small unit to several shifts for a plant room full of them. The shutdown is planned to fit, including evenings or weekends.
What do you clean inside the unit?
We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. Filters are cleaned or changed as agreed in the quote.
Which sectors do you work in?
Commercial premises of every kind: kitchens, offices, schools, healthcare, retail, leisure and food production. Work is timed around how each site runs.
Do you give a certificate after the clean?
Yes. Every clean comes with a TR19® certificate and a photo report. They’re worth keeping with the plant records.
How do you keep the site clean during the work?
Protection goes down first: floor sheeting and covers over nearby surfaces and equipment. The area is left tidy, with our waste taken away.
Is there a survey before the work?
Yes. Every job is surveyed first, from your photos and details, or with a visit where needed. Then you get a fixed quote.
Ventilation in Paddington Green buildings
Food Standards Agency records list about 92 schools, colleges and universities, about 32 caring premises (care homes, nurseries and hospitals) and about 183 hotels and guest houses registered as food businesses within roughly a mile and a half of the centre of Paddington Green. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Getting kit to a London plant room usually means lifts, stairs and an agreed loading slot. About 0.5 miles north-west of Paddington Green is Maida Vale Hospital for Nervous Diseases, the nearest hospital. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.
If you manage shops or offices close to London Paddington station, a TR19® Air inspection shows whether the ductwork needs cleaning. Maida Vale Hospital for Nervous Diseases, about 0.5 miles north-west, is the nearest hospital to Paddington Green, and healthcare sites of every size need their supply air kept clean.
Paddington Green is about 1 mile north-west of City of Westminster, in Greater London. We carry out AHU cleaning for commercial premises of every kind in Paddington Green and the rest of Greater London. Paddington Green is one of 764 places in Greater London where we work for commercial clients.
All of W2, W1H and NW8 is within our area for AHU cleaning, from busy streets to back roads. If you need AHU cleaning at premises on Harrow Road, Craven Road and Lanark Road or anywhere close by, our technicians can take on the work.

What’s near Paddington Green

Other landmarks nearby include Harrods (1.5 miles south) and London Toy & Model Museum (0.6 miles south-west). For a walk, there’s The Long Water and Greville Place nature reserve.
Common problems we fix in Paddington Green
Air handling units are usually tucked away on roofs, in plant rooms or above ceilings, so they’re easy to forget about. Months can pass without anyone looking inside.
What we are most often called out for:
- Blocked condensate drains and slimy trays
- Dust-coated heating and cooling coils
- Fan sections that haven’t been cleaned in years
- Odours coming through the supply air
Wherever a school like Ark Paddington Green Primary Academy has ducted ventilation, a half-term visit keeps the work out of lesson time.

- Whether inaccessible sections are listed on the report
- What hours they’ll be on site
- If the quote is a fixed price or an estimate
Part by part
Fans and fan sections
The fan moves all of the unit’s air, so dirt on it gets spread around. The impeller, its housing and the fan chamber are cleaned.
Filters
What’s on the filters is a good clue to what’s further in. They’re photographed before and after for your records.
Fixed quotes for AHU cleaning in Paddington Green
There’s no set price list, because sites vary so much. What we look at:
- Whether we need access equipment or extra panels
- Travel, parking and unloading
- How many systems or sites are involved
- When the work can happen, such as evenings, overnight or weekends
What you pay depends on how big the system is, what state it’s in and access to every part of it. You get a fixed price before any work starts, so you know where you stand.
Helping us quote
There’s no need for technical detail. It helps if you can send:
- The postcode and the type of business
- Wide photos of the system and the area around it
- The roof, plant room or outside wall the system runs to
- Any access panels or hatches you can see
Quotes are quick. Send a few details and pictures, and we usually reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
In-house cleaning or a specialist?
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Managing agents and facilities teams in Paddington Green
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We are happy to deal with either side and send the paperwork to whoever needs it.
From a single site to a large estate, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with pictures.
What happens on the day
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 the area around the work is covered and protected. On site, it takes a single shift for a typical unit, longer for large or heavily soiled ones. Expect the work in Paddington Green to happen after your last customer leaves, not during trading.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Getting ready for the visit
- Clear loose items from the work area
- Mention any locked doors, roof access or ceiling voids
- Allow time for equipment near the work to be turned off and cool down
Getting a quote
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before we start.
