Drain trays
Drain trays can rust and leak over time. Their condition goes into the report with photos so repairs can be planned.
AHU cleaning for kitchens and businesses in Chalksole Green
Every supply and extract system relies on the air handling unit at its centre: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Whatever builds up inside it travels with that air, so cleaning the unit matters as much as cleaning the ducts. If you have air handling units with blocked filters and blocked condensate drains and slimy trays, we can put it right, from supply and extract fans, dampers and louvres and heating and cooling coils onwards.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

Questions from Chalksole Green
Do you work in villages like Chalksole Green?
Yes. Chalksole Green is within the area we cover across London and the South East. A survey first, from pictures or a visit, means we arrive with the right kit.
Do you offer AHU cleaning in Chalksole Green?
Yes, Chalksole Green is covered. You can call us on 0345 646 2711 or email us and let us know what needs doing.
How much does AHU cleaning cost?
Size, condition, access and working hours all affect the cost. Ask us for a fixed quote, normally ready within one working day.
How do you protect the area?
With sheeting and covers, before anything else happens. The work is kept contained and leave the area clean.
Do you do ventilation duct cleaning too?
Yes, supply and extract ducts, grilles and diffusers. We will tell you after the survey whether the ducts need it.
What information do you need?
Just the basics: the address, the site type, your opening hours and how we reach the system. Photos and any previous paperwork make it quicker. Then ring 0345 646 2711 or email us.
How often do AHUs need cleaning?
There’s no single answer; it comes down to the building and the unit. Regular inspection shows when it’s due, and the report recommends a next date.
Do you have insurance?
Yes, we’re fully insured. CHAS and SafeContractor accreditation sit alongside it, for sites that check contractor safety.
What affects the cost of AHU cleaning
Before we fix a price, we need to know a few things. We look at:
- What state the system is in
- The scale of the work
- One-off work versus a regular cycle
- The number of sites or systems
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll go through it with you.
What to send for a quote
Photos let us diagnose from a distance. Try to include:
- Your opening hours and when the area is out of use
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- The postcode and the type of business
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
To get a fixed quote, phone us on 0345 646 2711, or send details by email and tell us the type of site, your opening hours and roughly what the system looks like. A few pictures and your last certificate or report help a lot. You’ll usually have a quote within one working day.
What staff can safely do
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.
Multi-site and managed buildings
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements, and we’ll send a fixed quote.
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we’re happy to quote for all of it.
What happens if it’s left?
If people in a building in Chalksole Green complain about stuffy or smelly air, the AHU is worth looking at. A clean tackles the source instead of masking it. In a small place like Chalksole Green, a system that fails can take a site out of use.
When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote and give you a fixed price before we start.

The process
The visit has three parts: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with photos. Most of the time goes on the work itself, and that takes from a few hours for a compact unit to a day or more for a large one. Somewhere as small as Chalksole Green, the date and timings are agreed with you well before the day.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Getting ready for the visit
- Let us know how we reach the system, including roofs, risers and plant rooms
- Make sure someone can let us in and lock up afterwards
- Tell us the best time to work, such as after service or at a weekend
How to get a quote
To help us quote: the address, the type of site and when it’s open, pictures of the system and the last certificate or report, if there is one. Once you have those, phone us on 0345 646 2711, or send details by email.

Aftercare tips
Good habits slow the build-up between visits. Our tips:
- Plan the next inspection before the last report gets filed away
- Make sure the unit’s access doors open easily
- File each AHU report in the maintenance log
- Check the drain tray is emptying during routine visits
We recommend when the unit should next be inspected or cleaned, taking into account how dirty it was. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.
