AHU cleaning for kitchens and businesses in Sleapshyde
No two plant rooms are the same, from a small ceiling-mounted unit to a large rooftop plant. We look at the unit first, from pictures or a site visit, and send you a fixed quote before any cleaning starts. If you have odours coming through the supply air and drain trays holding standing water, we can help.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
The paperwork matters as much as the work. Each visit is written up with photos, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

How it works
Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. The visit takes anything from half a day for one small unit to several shifts for a plant room full of them. Somewhere like Sleapshyde, lanes, gates and parking are worth mentioning in advance.
- 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, coils, fan section and casing are cleaned in turn.
- Drain trays are cleared and cleaned and the outlet checked.
- A TR19® certificate and photo report follow the clean.
Preparing for the visit
- Agree a time when the area can be out of use
- Dig out any earlier paperwork for the system
- Let us know about parking and loading

Your questions about AHU cleaning in Sleapshyde
Can ventilation in schools around Sleapshyde be cleaned out of term?
Yes. The holidays are the usual time for school work. With about 2 schools and colleges on the FSA’s register within roughly a mile and a half of Sleapshyde, it pays to plan holiday dates ahead. You can call us on 0345 646 2711, or email photos with the dates the site is empty.
Is Sleapshyde within the area you cover?
Yes, smaller places are covered as well as towns. Just mention lanes, gates or anything else about the site when you book.
What do you need from me for a quote?
A short description and a few pictures plus the address and your hours. We’ll ask for anything else we need.
Can you set up regular visits?
Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. Each report recommends when the next visit should be.
Will we get paperwork for the AHU clean?
Yes. You receive a certificate and a report showing each section before and after, with any faults we noticed.
What does TR19 mean?
BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not law, but it’s the benchmark.
What do you clean inside the unit?
Every section that collects dirt: filters, coils, tray, fan and panels. The survey confirms what’s in your unit before we quote.
What accreditations do you have?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We’re fully insured and have been trading since 2009.
How we price AHU cleaning
Every site gets its own quote. These are the things that affect it:
- The size of the system
- Whether several sites go on one quote
- Site requirements such as sign-in and permits
- One-off work versus a regular cycle
A single site or a whole portfolio, the quote is built the same way: the work involved, the access and the timing. You’ll have a fixed price before work begins.
Helping us quote
To help us quote quickly, send us:
- Any symptoms, from odd noises to smells or leaks
- The roof, plant room or outside wall the system runs to
- Close-ups of filters, grilles, hatches or access panels
- Your opening hours and when the area is out of use
Need a price for AHU cleaning? Please phone us on 0345 646 2711, or send details by email with a few details about the site. We’ll explain what we’d do and send a fixed quote before you commit to anything.
When to call us in Sleapshyde
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.
It’s time to book a visit if you see:
- Dirty coils holding back the airflow
- Plant that has been serviced but not cleaned
- Fan sections that haven’t been cleaned in years
- Leaves and litter drawn into the unit
If you run a surgery, dental practice or care home near Sleapshyde, clean ventilation matters as much to you as to a hospital like Hill End Hospital (about 1.7 miles west).
Comparing quotes
- Whether the quote is based on a survey or pictures
- What’s included in the scope, part by part
- Whether the work can be done while the site is closed
- How areas they cannot reach will be recorded
What your team can do, and what needs us
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We’ll take a look and send you a fixed quote.
Looking after it afterwards
Think of this as the after-treatment advice, in brief:
- Diary the inspection date recommended in the report
- Keep filter changes on time and recorded
- Note any water around the unit or leaks below it
- Make sure condensate is draining away
You receive a TR19® certificate and a photo report after the clean. Keep both with the building’s maintenance records.
Change or clean filters on time. Overloaded filters let more dirt through to the coils and fan.
Landlords, agents and facilities managers
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements and we’ll come back with a fixed quote.
Keeping records across a portfolio is half the battle. Every visit ends with a dated report and photos, ready to show insurers, fire officers or EHOs.
Different parts, different methods
Internal casing and panels
Damaged internal linings or loose panels can shed material into the air. Anything like that is recorded with pictures.
Filters
Filters are the first line of defence in the unit. We check them, and clean or change them as agreed in the quote, and the housing around them is cleaned too.
Sleapshyde buildings and their air
Food Standards Agency records list about 9 care, childcare and hospital premises registered as food businesses across Sleapshyde and its immediate surroundings (about a mile and a half). Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. About 18 miles out from central London, Sleapshyde is part of the South East area we work across. A survey and a fixed quote come first, then the visit at a time that suits you. For Sleapshyde, the closest hospital is Hill End Hospital, roughly 1.7 miles west. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.
Classrooms and halls at schools such as Colney Heath Junior Mixed Infant and Nursery School are easiest to work in when pupils are away.
