AHU cleaning in Upperton
Our AHU cleans for sites in Upperton cover the parts that collect dirt: filters, coils, drain trays, fans and the internal panels. You get a TR19® certificate and a photo report showing the unit before and after. Common call-outs are for drain trays holding standing water and air handling units due a clean after building work, on filter sections, supply and extract fans and drain trays.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
A written report with photos follows every visit, 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.

What affects the quote in Upperton
The price is fixed before any work begins. It takes into account:
- Whether several sites go on one quote
- The times the site is available
- Any permits to work or inductions
- A single visit or a regular plan
Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.
What to send for a quote
We can often survey from pictures. The most useful are:
- The postcode and the type of business
- Any access panels or hatches you can see
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- When the site is open and when it’s quiet
Quotes are quick. Send a few details and photos, and we normally reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
Your questions about AHU cleaning in Upperton
Is AHU cleaning available in Upperton?
Yes, Upperton is within the area we cover across London and the South East. Just phone us on 0345 646 2711, or send details by email with a few details of the site.
Do you work overnight in Upperton?
Yes, we can come after you close and finish before you open. The work in Upperton can fit around your hours. Let us know the hours you’re closed and we’ll book within them.
What types of premises do you cover?
All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. We fit the work around how the site operates.
Are you fully insured?
Yes. We’re fully insured, and the details are available on request.
Do you clean the ductwork as well?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. Cleaning the unit and ducts together often makes sense, and we can survey both on the same visit.
How long does an AHU clean take?
Typically the clean takes from a few hours for a compact unit to a day or more for a large one. We plan the shutdown around that, out of hours if needed.
How much notice should we give?
For planned work, earlier is better, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
What should I send you?
Just the basics: where it is, what kind of site, when it’s open and the access. Photos and the last report help too. After that, simply give us a ring on 0345 646 2711 or drop us a line.
Between visits
Here’s the after-treatment advice, in brief:
- Make sure the unit’s access doors open easily
- Flag stale or damp smells in the supply air
- Make sure condensate is draining away
- Store the TR19 paperwork where auditors can find it
Restart the unit with your site team or maintenance contractor once we’ve finished. Check the drain tray is emptying over the first few days to confirm water is draining away.
Check drain trays and condensate drains during routine maintenance. A drain that’s cleared early never gets to the slime stage.
For landlords and multi-site operators
Whether it’s one building or many, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with photos.
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we’re happy to quote for all of it.

The process
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. On site, the work takes one overnight shift for many single units, with bigger plant phased. Photos of the system and how to reach it help us plan a visit to Upperton.
- First the unit is surveyed, from pictures or a visit, and the scope agreed.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- We clean out the drain tray and make sure it drains.
- We close up the unit and send the certificate and before and after photos.
Before we arrive
- Mention any locked doors, roof access or ceiling voids
- Tell us about site rules, permits or sign-in
- Mention any parking or loading restrictions
Getting a quote
Here’s what helps us quote: where the site is, what it is and its opening hours, pictures of the system and the last certificate or report, if there is one. Then give us a ring on 0345 646 2711 or drop us a line.
Related advice
Do you need AHU cleaning in Upperton?
Cooling coils create condensation, and that water has to go somewhere. A blocked outlet or a badly sloped tray leaves standing water, and slime and smells soon follow.
Clients typically contact us when they notice something like this:
- Air handling units due a clean after building work
- Debris and leaves in the fresh air intake
- Dirty filters cutting the airflow
- Dust built up on fan impellers
In Upperton, we look inside the system before deciding what needs cleaning.

What staff can safely do
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That’s our job.
