About our AHU cleaning in Clatterford End
We clean the parts of the unit where dirt and moisture gather: filters, coils, drain trays, fans and the internal panels. Every clean comes with a TR19® certificate and before and after pictures in a report. If you are dealing with dust built up on fan impellers and condensate trays that won’t empty, we can put it right, from supply and extract fans, heating and cooling coils and internal panels onwards.
For a building in or near Clatterford End, access is agreed in advance and the visit is planned around the journey.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

What the work involves, part by part
Filters
Filters are the first line of defence in the unit. As part of the clean, filters are checked and cleaned or replaced as agreed, and the housing around them is cleaned too.
Rooftop and plant room units
Units on roofs and in plant rooms can be awkward to reach. We plan safe access as part of the survey, before we quote.
Aftercare tips
After the visit, a few habits help the work last:
- Keep filter changes on time and recorded
- Plan the next inspection before the last report gets filed away
- Don’t ignore odours coming through the grilles
- Keep the area around the fresh air intake clear
Keep filter changes on schedule between cleans, as that does more than anything to keep the unit clean. Log every change so it’s easy to see when the next is due.
Make sure access doors and panels on the unit open easily. Sections that are awkward to open are the ones that get skipped.
What we do, step by step
Protection comes first: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. The work on site takes one overnight shift for many single units, with bigger plant phased, and we clear up before we go. For a village or hamlet like Clatterford End, tell us about narrow lanes, gates and parking when you book.
- 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.
- Standing water and slime come out of the tray and the drain is checked.
- You get a TR19® certificate and a photo report.
Before we arrive
- Mention any locked doors, roof access or ceiling voids
- Arrange a key holder or contact on site
- Mention any sign-in, permit or induction we need
Ask for a quote
The quickest way to a quote is to send pictures: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.

What we’re called out for in Clatterford End
Air handling units are normally tucked away on roofs, in plant rooms or above ceilings and are rarely seen by anyone but maintenance staff. Months can pass without anyone looking inside.
Any of these means the system needs a check-up:
- Drain trays holding standing water
- Dust-coated heating and cooling coils
- Dirty filters cutting the airflow
- Fan sections that haven’t been cleaned in years
Ventilation work in and around Clatterford End is risk-based: inspect, then clean what needs it.
Before you book anyone
- If the quote is a fixed price or an estimate
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- How areas they cannot reach will be recorded
- Whether the whole system is included, or only the parts that are easy to reach
For landlords and multi-site operators
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.
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.

Clatterford End: your questions answered
Do you work at weekends in Clatterford End?
Yes, out-of-hours work is a big part of what we do. The work in Clatterford End can fit around your hours. When you call 0345 646 2711 or use the quote form, mention when the site is quiet.
Is Clatterford End within the area you cover?
Yes. Clatterford End is within the area we cover across London and the South East. Photos of the system and directions to the site help us plan the visit.
How long does it take to clean an air handling unit?
Cleaning takes from a few hours for a compact unit to a day or more for a large one. Large plant can be split over several shifts, so ring 0345 646 2711, or send details by email to talk it through.
Do you need to switch the unit off?
Yes. Cleaning needs the unit off and isolated, so we plan it for a time that suits the building.
Do you offer emergency callouts?
Yes. There’s a 24/7 emergency line, for problems that cannot wait. Call us any time and explain what’s happened.
Is there a report after cleaning?
Yes. A TR19® certificate and photo report are sent after the clean, including anything we think needs attention.
What types of premises do you cover?
All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. Work is timed around how each site runs.
Which parts of an air handling unit do you clean?
All the internal parts the air touches, from the intake and filters through the coils and fan to the outlet. You get a photo report showing each part before and after.
Leave it or put it right?
A clogged coil or dirty fan makes the unit work harder for the same airflow. That means more wear on the motor and rooms that feel less fresh, and a clean on your terms beats a breakdown on nobody’s. A fault that closes a site in a village like Clatterford End affects everyone who depends on it.
Kitchens, offices, schools and hospitals are all priced 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 will go through it with you.
