AHU cleaning in Churchgate, done properly
No two plant rooms are the same, whether it’s a compact unit in a ceiling void or a big unit on the roof. Every job starts with a survey, from pictures or on site, followed by a fixed quote before any cleaning starts. Typical jobs include intake sections clogged with outdoor debris and fan sections that haven’t been cleaned in years, across supply and extract fans, heating and cooling coils and filter sections.
In a place like Churchgate, air handling units are often tucked into roof spaces or small plant rooms, out of sight and easy to overlook. Filters, coils and drain trays need attention whatever the size of the unit.
For insurers and inspectors, the record counts. So every job comes with a written report and pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Signs you need AHU cleaning in Churchgate
Cooling coils create condensation, and that water has to go somewhere. If the drain tray outlet blocks or the tray does not fall properly, water stands in it, and slime and smells soon follow.
Clients typically contact us after spotting something like this:
- Air handling units never cleaned inside
- Condensate trays that won’t empty
- Units needing a clean before a new tenant or handover
- Leaves and litter drawn into the unit
Classrooms and halls at schools such as Dewhurst St Mary CofE Primary School are easiest to work in when pupils are away.
Questions to ask before booking
- Proof of insurance
- Which accreditations they hold, and whether you can check them
- Whether the price is fixed
- Whether a written report and pictures are included
What we do, step by step
We are used to working while the site is closed. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. The visit itself takes anything from half a day for one small unit to several shifts for a plant room full of them. Around Churchgate, access is usually simpler than in a town centre, though gates and roof access are worth mentioning.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- The unit is shut down with your site team and the area protected.
- Filters, coils, fan section and casing are cleaned in turn.
- We clean out the drain tray and make sure it drains.
- A TR19® certificate and photo report follow the clean.
Getting ready for the visit
- Mention any sign-in, permit or induction we need
- Make sure equipment near the work can be switched off and left to cool
- Mention any parking or loading restrictions
Ask for a quote
Quotes are quick. Send a few details and pictures, and we usually reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
Related advice
For landlords and multi-site operators
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We’re happy to deal with either side and send the paperwork to whoever needs it.
Multi-site operators often want one contractor and one number. We cover South East England and London, so a run of sites can go into one programme and kept on a regular cycle.
Why deal with it now?
Cleaning a unit while it only has light dust is quick. Years of build-up make the job longer and harder, particularly where damp has made it stick. A visit arranged in advance is far less disruptive than a callout on a busy day.
You will not find a price list here, because each job is priced on what it involves. Call for a fixed quote, and we’ll explain what it covers.

What your team can do, and what needs us
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We can diagnose it and quote.
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Questions from Churchgate
Do you work in villages like Churchgate?
Yes. Villages and rural sites across the South East are part of our work, Churchgate included. The journey is planned ahead, so a few details about the route help.
Can the work in Churchgate be done at night or at weekends?
Yes, nights and weekends are routine for us. It means the site in Churchgate keeps running as normal. Your opening times are the first thing we ask for.
Do you have insurance?
Yes, we’re fully insured. We also hold CHAS and SafeContractor for clients who vet their contractors.
Do you have a 24/7 line?
Yes. Our emergency line runs 24/7, for problems that can’t wait. Call us any time and explain what’s happened.
Do you look at the system first?
Yes, every time. Diagnosis comes before treatment: the survey shows what needs doing and what access we need and the fixed quote is built on it.
What does AHU cleaning cost?
Size, condition, access and working hours all affect the cost. Ask us for a fixed quote, usually ready within one working day.
What do you do to protect the area?
Floors and surfaces near the work are sheeted before we start, and anything we remove is contained. At the end, the area is cleaned down.
How long does it take to clean an air handling unit?
It takes from a few hours for a compact unit to a day or more for a large one. Size, layout and how dirty it is decide the rest, and we will confirm the time when we quote.
Between visits
Once we’ve finished, these simple steps help:
- Diary the inspection date recommended in the report
- Stick to the filter change plan
- Check the drain tray is emptying during routine visits
- Don’t store bins or materials near the intake
When we have closed the unit up, it can be restarted with your site team. Check the drain tray is emptying over the first few days to confirm water is draining away.
Regular filter changes are the best protection an AHU has. Once filters clog, dirt starts getting past them.
