What affects the quote in Yiewsley
Before we fix a price, we need to know a few things. We check:
- The size of the system
- Whether it’s a one-off visit or part of a schedule
- Access, including roofs, risers and ceiling voids
- Site rules, permits and inductions
Several systems or sites on one quote often makes better use of the time. Mention every system or site you need covered, and you’ll get one fixed quote.
Helping us quote
There’s no need for technical detail. It helps if you can send:
- How we’d reach plant on a roof or in a plant room
- Close-ups of filters, grilles, hatches or access panels
- Wide pictures of the system and the area around it
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
For AHU cleaning in Yiewsley, phone us on 0345 646 2711, or email photos. Let us know the site type and the opening hours, plus photos or the previous report if they’re to hand. We usually send a fixed quote within one working day.
AHU cleaning in Yiewsley, done properly
We clean the parts of the unit where dirt and moisture gather: filters, coils, drain trays, fans and the internal panels. You get a TR19® certificate and a photo report showing the unit before and after. If you have dirty filters cutting the airflow and air handling units never cleaned inside, we can help, from dampers and louvres, internal panels and drain trays onwards.
London buildings often depend on air handling units in plant rooms or on the roof to supply fresh air. For a building in Yiewsley, dust settles in the units and ducts year after year.
Each visit ends with a written report and pictures, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

In-house cleaning or a specialist?
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
What a clean won’t put right
An honest diagnosis matters more to us than a booking, so here’s what this work cannot put right:
- Mechanical faults with motors, belts or bearings
- Building management system faults
- Leaking heating or cooling coils
Not sure which it is? You can call us on 0345 646 2711, or send details by email and we’ll tell you honestly.
What the work covers
- Dampers and louvres

What else we do in Yiewsley
What happens on the day
Our technicians bring everything the work needs, including protection sheets, the right tools and access kit. You only need to give us clear access and switch off what needs to be off. On site, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. We fit London jobs around the building rather than the other way round, so a visit in Yiewsley is typically out of hours.
- We survey the unit from pictures or on site and agree what’s included.
- The unit is shut down with your site team and the area protected.
- Filters, coils, fan section and casing are cleaned in turn.
- We clean out the drain tray and make sure it drains.
- A TR19® certificate and photo report follow the clean.
How to prepare
- Make sure equipment near the work can be switched off and left to cool
- Mention any parking or loading restrictions
- Let us know how we reach the system, including roofs, risers and plant rooms

FAQs for Yiewsley
How do you handle parking and loading in Yiewsley?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Night visits tend to make loading easier on London streets.
Can a school’s ventilation in Yiewsley be done out of term time?
Yes. The holidays are the usual time for school work. Food Standards Agency records list about 29 schools, colleges and universities with registered kitchens within about a mile and a half of Yiewsley. You can ring 0345 646 2711 or send us an email with the dates the site is empty.
Do you work evenings or weekends?
Yes. Evening, overnight and weekend work is all possible, so the building keeps running in the day.
What happens to the waste?
It’s contained and taken away. We collect grease, debris and waste water as we go rather than letting it spread.
Do you have a 24/7 line?
Yes. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line, and we will advise on what to do next.
Can you look after several sites?
Yes. We work across South East England and London, so we can schedule a run of sites as one programme. Each site gets its own report and photos.
Can you quote from photos?
Normally, yes. Send wide shots, close-ups of any access panels and anything that worries you, and we typically come back within one working day. Some sites still need a visit, and we’ll say so.
Are you insured?
Yes, fully. CHAS and SafeContractor accreditation sit alongside it, for sites that check contractor safety.
Do you need AHU cleaning in Yiewsley?
Dirt in an AHU matters in two ways: the unit supplies the air people breathe, and a dirty unit has to work harder. For the people using the building every day, that is the air they breathe for hours on end.
It’s time to book a visit if you see:
- Rooms that smell stuffy when the system runs
- Coils clogged with dust and debris
- Dust built up on fan impellers
- Units that have only ever had filter changes
School buildings such as Rabbsfarm Primary School are normally done in the holidays, so classrooms aren’t disturbed.
Questions to ask before you book
- What’s included in the scope, part by part
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- What happens if part of the system cannot be accessed
- Whether they’re fully insured
What happens if it’s left?
Dirty coils and fans make the unit strain to move the same air. The result is extra wear and a building that does not feel as comfortable, and a planned clean is far less disruptive than a breakdown. It’s better booked as a planned job in Yiewsley than handled as an emergency.
Working hours, access and the scale of the site all affect the cost. Each of those is built into the quote, and the price is fixed before we start.

Different parts, different methods
Filters
Dirty filters cut airflow and let dirt slip past their frames. The filter section is cleaned so new or cleaned filters sit properly.
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. We clean them with care so the fins are not damaged.
Ventilation in Yiewsley buildings
Food Standards Agency records list about 29 schools, colleges and universities, about 29 care, childcare and hospital premises and about 9 hotels and guest houses registered as food businesses within 1.5 miles or so of the middle of Yiewsley. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. Hillingdon Hospital is the nearest hospital, about 0.7 miles north of Yiewsley.
