About our AHU cleaning in Sundridge
All the building’s air passes through the fan, so dirt on the impeller and housing gets spread around. We clean the fan section along with the rest of the unit, with the unit switched off and made safe first. The work covers supply and extract fans, drain trays and heating and cooling coils, and the jobs we see most are drain trays holding standing water and air handling units never cleaned inside.
Somewhere as small as Sundridge, ducted ventilation is normally limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

What affects the cost of AHU cleaning
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Working hours and out-of-hours timing
- Travel, parking and unloading
- The size of the system
- One-off work versus a regular cycle
One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. You will have a fixed price before any work starts.
Asking for a quote
The more you tell us, the more accurate the quote. With your enquiry, please include:
- The times we could work without disrupting the site
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- How we’d reach plant on a roof or in a plant room
- Any previous report or certificate
We don’t publish a price list, because no two systems are the same. Instead, we look at your site first, from pictures or a survey, and then give you a fixed quote. To start, ring 0345 646 2711 or drop us a line.
Staff cleaning versus specialist work
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
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 do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.

What happens on the day
Our technicians bring everything the work needs, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. The visit takes one overnight shift for many single units, with bigger plant phased. The timing of a visit to Sundridge is set by you, and the travel is our side of the planning.
- We start with a survey of the unit and a fixed quote for the work.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters, coils, fan section and casing are cleaned in turn.
- Standing water and slime come out of the tray and the drain is checked.
- You get a TR19® certificate and a photo report.
How to prepare
- Have your last certificate or report to hand
- Mention any locked doors, roof access or ceiling voids
- Arrange a key holder or contact on site
Getting a quote
Here’s what helps us quote: the address, the type of site and when it’s open, photos of the system and any previous report or certificate. Once you have those, call us on 0345 646 2711, or send details by email.

What happens if it’s left?
Standing water in a drain tray doesn’t clear itself. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Clearing it now is a much smaller job. A planned visit to Sundridge is easier to arrange than an emergency callout.
What you pay reflects the actual work. That’s why every job is surveyed first, and why the quote is fixed before we start.
Why book with us
- Every visit written up, with photos
- Fixed quotes from a survey or photos

How the job changes from site to site
Internal casing and panels
Dust settles on every internal surface of the unit. Each section is cleaned from the intake through to the outlet.
Rooftop and plant room units
Units outside are exposed to weather and windblown debris. The intake section gets particular attention.
Sundridge: your questions answered
Do you cover Sundridge for AHU cleaning?
Yes. We work across London and the South East, and Sundridge is part of that. You can ring 0345 646 2711 or drop us a line and let us know what needs doing.
Do you cover smaller places like Sundridge?
Yes. Sundridge is within the area we cover across London and the South East. A survey first, from photos or a visit, means we arrive with the right kit.
How long does it take to clean an air handling unit?
Expect it to take a single shift for a typical unit, longer for large or heavily soiled ones. Size, layout and how dirty it is decide the rest, and we will confirm the time when we quote.
Do you look at the system first?
Yes. We always survey first, from your pictures and details, or with a visit where necessary. A fixed quote follows.
What about areas you can’t get to?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, and we can fit those.

Yes. Every clean comes with a TR19® certificate and a photo report. Keep them in the maintenance log.

Not every problem is solved by AHU cleaning, and we will tell you before work begins. It won’t put right:
- Airflow problems caused by the system’s design
- Coils that are corroded or leaking and need replacing
- Building management system faults
If in doubt, phone us on 0345 646 2711, or email photos and we will say what we think.
