Signs you need AHU cleaning in Boyton Cross
Most units live out of sight on roofs, in plant rooms or in ceiling voids, so they’re easy to forget about. Months can pass without anyone looking inside.
Keep an eye out for any of the following:
- Plant that needs cleaning after a refit
- Air handling units never cleaned inside
- Dirty fans and fan housings
- Blocked condensate drains and slimy trays
School buildings such as Newlands Spring Primary School are usually done in the holidays, so classrooms are not disturbed.

AHU cleaning for kitchens and businesses in Boyton Cross
Coils are where a lot of the dirt ends up. A coated coil restricts airflow and makes the unit work harder. Coils are cleaned carefully, with methods chosen so the fins are not flattened. The work covers heating and cooling coils, supply and extract fans and filter sections, and common reasons people get in touch are filters that are clogged or overdue and blocked condensate drains and slimy trays.
Somewhere as small as Boyton Cross, ducted ventilation is normally limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
Insurers, fire officers and environmental health officers all look at records. That’s why every job is written up in a report with photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

How we price AHU cleaning
You will get a fixed price before work begins. It’s based on:
- The size of the system
- How many systems or sites are involved
- How easy every part is to reach
- Any permits to work or inductions
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we’ll go through it with you.
What we need to know
To help us quote quickly, send us:
- Where the site is and what kind of site it is
- The paperwork from the last visit, if you have it
- Problems your staff have spotted
- The times we could work without disrupting the site
The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and we can price many jobs without a visit.
The process
The visit has three parts: 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. The middle part takes longest, which takes one overnight shift for many single units, with bigger plant phased. The timing of a visit to Boyton Cross is set by you, and the travel is our side of the planning.
- We start with a survey of the unit and a fixed quote for the work.
- We arrange the shutdown with your staff and sheet the area.
- Filters, coils, fan section and casing are cleaned in turn.
- Drain trays are cleared and cleaned and the outlet checked.
- You get a TR19® certificate and a photo report.
How to prepare
- Find the previous report, if there is one
- Clear loose items from the work area
- Plan for cooking equipment or plant to be off before we arrive
Getting a quote
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before work begins.
Advice
Why act early in Boyton Cross
Leave an AHU uncleaned and the dirt does not stay put. It moves on into the ductwork and out into the rooms, so cleaning the ducts without the unit only goes so far. 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, which can make the next visit longer. If you’re not sure what’s needed, give us a ring on 0345 646 2711, or email photos for straight advice and a fixed quote.

Looking after it afterwards
Here’s the after-treatment advice, short and simple:
- Do not store bins or materials near the intake
- Don’t ignore odours coming through the grilles
- Keep the certificate and photo report with the plant records
- Keep inspection doors on the unit in good order
The report shows each section of the unit before and after, along with anything we couldn’t reach. It also notes faults we spotted, such as damaged panels or a blocked drain.
Keep the unit’s doors and panels in working order. Sections that are awkward to open are the ones that get skipped.
For landlords and multi-site operators
Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and pictures, so records stay tidy.
Your questions about AHU cleaning in Boyton Cross
Is AHU cleaning available in Boyton Cross?
Yes, Boyton Cross is within the area we cover across London and the South East. You can call us on 0345 646 2711 or email us and tell us what needs doing.
Do you cover smaller places like Boyton Cross?
Yes, Boyton Cross is part of our area, however small the site. Photos of the system and directions to the site help us plan the visit.
What types of premises do you cover?
All kinds of commercial and public premises: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. We fit the work around how the site operates.
Will the ventilation be off while you clean?
Yes, for the time we are working on it. Out-of-hours work is available so the building is not left without ventilation when it’s busy.
Do you clean the ductwork as well?
Yes, the ductwork, grilles and diffusers the unit serves. The survey shows whether the ducts need cleaning now.
Do you survey before quoting?
Yes. For many sites, pictures and a few details are enough, and larger or hidden systems get a visit.
Can you fix a faulty AHU?
The clean includes noting faults, but repairs sit with your maintenance contractor, with pictures where it helps.
How often do AHUs need cleaning?
That’s set by inspection, in line with TR19® Air. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.

What else we do in Boyton Cross
What staff can safely do
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
