About our AHU cleaning in Rowhook
Coils are where a lot of the dirt ends up. A coated coil restricts airflow and makes the unit work harder. We clean coils with methods suited to their condition, taking care not to damage the fins. We’re often asked to deal with intake sections clogged with outdoor debris and dirty filters cutting the airflow, on internal panels, filter sections and supply and extract fans.
For a building in or near Rowhook, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Good records are part of the job. Each visit is written up with pictures, 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.

What affects the cost of AHU cleaning
A fixed price needs a few facts first. We check:
- Working hours and out-of-hours timing
- How many systems or sites are involved
- Where the site is and how we reach it
- Any permits to work or inductions
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we’ll explain each part.
What to send for a quote
The more you tell us, the more accurate the quote. With your enquiry, please include:
- The postcode and the type of business
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Your opening hours and when the area is out of use
- Photos showing the whole system and its surroundings

Ventilation in Rowhook buildings

At about 31 miles from central London, Rowhook sits well inside the area we cover. The visit is fixed around your opening hours, not ours.
Hospitals such as Horsham Hospital (about 3.7 miles south-east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Rowhook are no different. School buildings such as Farlington School are normally done in the holidays, so classrooms aren’t disturbed.

Keeping the system healthy
How long the results last depends on use and care. Here’s what we suggest:
- Make sure condensate is draining away
- Diary the inspection date recommended in the report
- Clear leaves and litter away from the intake
- Keep the certificate and photo report with the plant records
Once the clean is done, we send a TR19® certificate and a report with before and after pictures. They belong in the plant or maintenance log.
Make sure access doors and panels on the unit open easily. Sections that are awkward to open are the ones that get skipped.
Multi-site and managed buildings
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
Why it’s worth doing now in Rowhook
Leave an AHU uncleaned and the dirt doesn’t stay put. It moves on into the ductwork and out into the rooms, which is why the unit and the ducts are best cleaned together. Rural sites can’t always move to another kitchen or room when something fails.
We do not list prices on the website, because each job is priced on what it involves. Call for a fixed quote, and we will talk you through it.

Common questions in Rowhook
Can ventilation in schools around Rowhook be cleaned out of term?
Yes, out-of-term visits are normal for schools. Around Rowhook, the Food Standards Agency lists about 2 schools and colleges with registered kitchens within a mile and a half or so. Send us your term dates when you ring 0345 646 2711 or drop us a line, and we’ll fit the work in.
Is Rowhook within the area you cover?
Yes. Villages and rural sites across the South East are part of our work, Rowhook included. A survey first, from pictures or a visit, means we arrive with the right kit.
Do you have a 24/7 line?
Yes. Our emergency line runs 24/7 for anything that cannot wait until a planned visit. Call us any time and explain what’s happened.
Can you set up regular visits?
Yes. Scheduled maintenance plans are part of what we do, with visits at the interval your system needs. Each report recommends when the next visit should be.
Can you clean without disrupting the building?
Yes. We work evenings, overnight and weekends, so offices, schools and shops can carry on.
Can you look after several sites?
Yes. Our area covers London and the South East, so sites at different addresses can be planned together as one programme. Every site has its own report.
How long will the unit be out of action?
Expect it to take half a day to a full day per unit, with large plant planned over several shifts. Size, layout and how dirty it is decide the rest, and the quote will give you a clear idea.
What accreditations do you have?
We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.
The process
There are three stages on the day: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with pictures. 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. A quick note on how to find the site and where to park makes a visit to Rowhook run smoothly.
- First the unit is surveyed, from pictures or a visit, and the scope agreed.
- We arrange the shutdown with your staff and sheet the area.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Standing water and slime come out of the tray and the drain is checked.
- We close up the unit and send the certificate and before and after photos.
Before we arrive
- Mention any parking or loading restrictions
- Tell us the best time to work, such as after service or at a weekend
- Make sure equipment near the work can be switched off and left to cool

Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. The coil and its drain tray are cleaned as one job.
Drain trays
Drain trays can rust and leak over time. Their condition goes into the report with pictures so you can decide on any repairs.
