AHU cleaning in Plaistow
Units vary a lot in size, age and layout, from a small ceiling-mounted unit to a large rooftop plant. We look at the unit first, from photos or a site visit, and send you a fixed quote, so you know where you stand. If you have filters that are clogged or overdue and dirty fans and fan housings, we can help.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
For insurers and inspectors, the record counts. That’s why every job is written up in a report with photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

What happens if it’s left?
Stuffy rooms and stale smells in a building in Plaistow can sometimes be traced back to the AHU. A clean tackles the source instead of masking it. If the system at a site near Plaistow fails, there may be nowhere nearby to move to.
What you pay reflects the actual work. That is why every job is surveyed first, and why the quote is fixed before work begins.

How we price AHU cleaning
There’s no set price list, because sites vary so much. The quote depends on:
- Parking and loading at the site
- The number of sites or systems
- How easy every part is to reach
- Site rules, permits and inductions
One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. The price is fixed before work begins.
What to send for a quote
The more you tell us, the more accurate the quote. With your enquiry, please include:
- The postcode and the type of business
- Wide photos of the system and the area around it
- How we’d reach plant on a roof or in a plant room
- When the site is open and when it’s quiet
There’s no standard price list, because every site is different. We look at your system first, from pictures or on a visit, then send a fixed quote. To start, phone us on 0345 646 2711, or send details by email.
Plaistow questions
Can you get to a site in Plaistow?
Yes, Plaistow is part of our area, however small the site. Photos of the system and directions to the site help us plan the visit.
Do you work overnight in Plaistow?
Yes. We work evenings, overnight and at weekends. That way a site in Plaistow does not have to lose a day’s trading. Let us know the hours you’re closed and we will book within them.
What do you clean inside the unit?
All the internal parts the air touches, from the intake and filters through the coils and fan to the outlet. You get a photo report showing each part before and after.
How much does AHU cleaning cost?
Every site is different, so each gets its own fixed quote. To get one, call 0345 646 2711, or send details by email with the site type, opening hours and a few pictures.
Do you survey before quoting?
Yes, always. We diagnose before we treat: the survey shows what needs doing and what access we need and the fixed quote is built on it.
How often do AHUs need cleaning?
That’s set by inspection, in line with TR19® Air. Units in heavy use or in sensitive buildings may need attention more often.
What about areas you cannot get to?
The report shows them clearly. In ductwork, new access panels are often the answer, which we can install.
What information do you need?
Just the basics: where it is, what kind of site, when it’s open and the access. Photos and the last report help too. Then give us a ring on 0345 646 2711 or send us an email.
Multi-site and managed buildings
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Each site gets its own report and photos, so each one has its own record.
Whether it’s one building or many, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.

Signs you need AHU cleaning in Plaistow
No filter stops everything. The fine dust that passes the filters lands on the coils, the fan and the internal panels, building up layer by layer.
If you notice any of these, it’s worth a diagnosis:
- Odours coming through the supply air
- Air handling units never cleaned inside
- Filters that are clogged or overdue
- Dirty fans and fan housings
Classrooms and halls at schools such as Plaistow and Kirdford Primary School are easiest to work in when pupils are away.
What to look for in a quote
- What’s included in the scope, part by part
- When they can work, and whether that’s outside your opening hours
- What happens if part of the system cannot be accessed
- Proof of accreditation you can verify
How the job changes from site to site
Fans and fan sections
Every bit of air passes the fan, so a dirty fan sends dirt downstream. We clean the impeller, housing and surrounding section.
Drain trays
Drain trays can rust and leak over time. We record their condition with photos so you can decide on any repairs.
What happens on the day
A visit follows the same order every time: sheeting and protection first, make the system safe, do the work, tidy up and hand over the paperwork. The visit itself takes anything from half a day for one small unit to several shifts for a plant room full of them. A few pictures of the system help us make the most of a visit to a place like Plaistow.
- 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.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
How to prepare
- Allow time for equipment near the work to be turned off and cool down
- Have your last certificate or report to hand
- Name a contact who can let us in at the agreed time
Getting a quote
To get a fixed quote, ring 0345 646 2711 or use the quote form with the site type, your trading hours and a short description of the system. A few photos and your last certificate or report help a lot. We normally come back within one working day.

What staff can safely do
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
