For landlords and multi-site operators
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
We also work for facilities teams across offices, schools and healthcare across Hampshire. Work can be phased by floor, building or site to keep disruption down.
AHU cleaning for kitchens and businesses in Houghton
Drain trays under cooling coils are meant to empty. If the outlet blocks, standing water and slime build up, right in the path of the air going into the building. Cleaning and clearing it is a key part of the job. Common call-outs are for dirty coils holding back the airflow and air handling units due a clean after building work, across drain trays, supply and extract fans and filter sections.
Work in a small place like Houghton starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Insurers, fire officers and environmental health officers all look at records. 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.

What AHU cleaning can’t fix
We will always give you a straight diagnosis, so here’s what AHU cleaning won’t do:
- Ventilation that was badly designed in the first place
- Building management system faults
- Leaking heating or cooling coils
If in doubt, give us a ring on 0345 646 2711 or drop us a line and we will say what we think before you book.

Part by part
Rooftop and plant room units
Many AHUs sit on roofs or in plant rooms with limited access. We plan safe access as part of the survey so the quote reflects it.
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. We clean them with care so the fins are not damaged.
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 the same goes into the written report. All told, the work takes one overnight shift for many single units, with bigger plant phased. Pictures of the system and its access let us plan the work in Houghton before we set off.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- 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
- 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
- Make sure someone can let us in and lock up afterwards
Ask for a quote
To get a fixed quote, give us a ring on 0345 646 2711, or send details by email and tell us the type of site, your opening hours and roughly what the system looks like. A few pictures and your last certificate or report help a lot. We typically come back within one working day.

Staff cleaning versus specialist work
Staff cleaning does not 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.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Questions from Houghton
Do you offer AHU cleaning in Houghton?
Yes. We work across London and the South East, and Houghton is part of that. You can phone us on 0345 646 2711 or use the quote form and tell us what needs doing.
Do you work at weekends in Houghton?
Yes, nights and weekends are routine for us. That way a site in Houghton doesn’t have to lose a day’s trading. Just call 0345 646 2711 or drop us a line with your opening times and we’ll plan around them.
What do you clean inside the unit?
Filters, coils, drain trays, the fan and the internal surfaces are all covered. Filters are cleaned or changed as agreed in the quote.
What do you need from me for a quote?
Some photos and a quick description of the system plus the address and your hours. We will ask for anything else we need.
How much notice do you need?
It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and for anything urgent, ring our 24/7 emergency line.
Are you fully insured?
Yes, fully. CHAS and SafeContractor accreditation sit alongside it, for sites that check contractor safety.
How much does AHU cleaning cost in Houghton?
It depends on the site, so we quote each one individually. For a quote, call us on 0345 646 2711, or send details by email with the site type, opening hours and a few pictures.
Do you have a 24/7 line?
Yes. There’s a 24/7 emergency line, for problems that cannot wait. Call us any time and explain what’s happened.
What happens if it’s left?
Dirty coils and fans make the unit strain to move the same air. That means more wear on the motor and rooms that feel less fresh, and a planned clean is far less disruptive than a breakdown. In a small place like Houghton, a system that fails can take a site out of use.
Combining work into one visit or one programme can make for a more efficient booking. Mention every system or site you need covered, and you’ll get one fixed quote.
