AHU cleaning for kitchens and businesses in Orchard Leigh
A cooling coil drips condensate into a tray that should drain away. When the drain blocks, water sits there and the tray turns slimy, right in the path of the air going into the building. Cleaning and clearing it is a key part of the job. If you have rooms that smell stuffy when the system runs and dirty fans and fan housings, we can help, from dampers and louvres, drain trays and heating and cooling coils onwards.
Work in a small place like Orchard Leigh starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

What staff can safely do
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.

Landlords, agents and facilities managers
Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.
Keeping records across a portfolio is half the battle. Each visit ends with a dated report and pictures, ready to show insurers, fire officers or EHOs.
What happens on the day
We’re used to working while the site is closed. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. On site, the work takes from a few hours for a compact unit to a day or more for a large one. A quick note on how to find the site and where to park makes a visit to Orchard Leigh run smoothly.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Before we arrive
- Make sure someone can let us in and lock up afterwards
- Agree a time when the area can be out of use
- Move anything stored near the system
How to get a quote
Getting a quote does not take long. Send a few details and pictures, and we typically reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.

What we are called out for in Orchard Leigh
Dirt in an AHU matters in two ways: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For the people using the building every day, that is the air they breathe for hours on end.
Any of these means the system needs a check-up:
- Filters that are clogged or overdue
- Units needing a clean before a new tenant or handover
- Dirty coils holding back the airflow
- Dust built up on fan impellers
If you manage a school such as Ley Hill School, ventilation cleaning is best booked for the holidays.
Before you book anyone
- Whether the work can be done while the site is closed
- Whether the whole system is included, or only the parts that are easy to reach
- If they look at the system before pricing
- If the quote is a fixed price or an estimate
What affects the cost of AHU cleaning
We quote each job individually. This is what makes a difference:
- Site rules, permits and inductions
- Access, including roofs, risers and ceiling voids
- Whether several sites go on one quote
- Parking and loading at the site
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.
Helping us quote
We can often survey from photos. Try to include:
- The site address and the type of premises
- Your last certificate, test record or report
- Wide photos of the system and the area around it
- Your opening hours and when the area is out of use

Can ventilation in schools around Orchard Leigh be cleaned out of term?
Yes, and it’s the easiest time to do it. Around Orchard Leigh, the Food Standards Agency lists about 6 schools and colleges with registered kitchens within a mile and a half or so. Just phone us on 0345 646 2711, or email photos with your term dates and we’ll plan around them.
Do you offer maintenance contracts?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. The report from each visit recommends the next date.
Do you have insurance?
Yes. We carry full insurance and have been trading since 2009.
What accreditations do you have?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We are fully insured and have been trading since 2009.
What happens if you can’t reach some of it?
Anything we cannot reach goes on the report, with pictures where possible, and we explain what access is needed, such as extra access panels in ductwork.
Do you give a certificate after the clean?
Yes, a TR19® certificate and a photo report. It includes a recommended date for the next check.
Is there a survey before the work?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
Why it’s worth doing now in Orchard Leigh
Cleaning a unit while it only has light dust is quick. Years of build-up make the job longer and harder, especially where there’s been moisture. Systems in rural buildings are often out of sight and out of mind.
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you’re unsure, phone us on 0345 646 2711, or email photos and we’ll give you an honest view and a fixed quote.

Filters
Every AHU relies on its filters to catch dust before it reaches the coils. We check them, and clean or change them as agreed in the quote, and the housing around them is cleaned too.
Rooftop and plant room units
Many AHUs sit on roofs or in plant rooms with limited access. Access is planned during the survey so the quote reflects it.
