What your team can do, and what needs us
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
AHU cleaning for kitchens and businesses in Chatham Green
All the building’s air passes through the fan, so dust on its blades and housing ends up in the airstream. Fan, housing and the surrounding panels are cleaned as part of the job, with the unit switched off and made safe first. If you’re dealing with stale or musty smells from the ventilation and drain trays holding standing water, we can help, from drain trays, heating and cooling coils and filter sections onwards.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

Chatham Green questions
Can you get to a site in Chatham Green?
Yes, smaller places are covered as well as towns. Let us know about access, parking and anything unusual about getting there when you book.
Do you work overnight in Chatham Green?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Chatham Green needn’t be disturbed. When you call 0345 646 2711, or send details by email, mention when the site is quiet.
What happens if you can’t reach some of it?
The report shows them clearly. In ductwork, new access panels are often the answer, and we can fit those.
Which accreditations do you hold?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We’ve been trading since 2009 and we are fully insured.
Which parts of an air handling unit do you clean?
Everything inside the unit that air passes over, from the intake and filters through the coils and fan to the outlet. The photo report shows each section before and after.
Which kinds of sites do you work on?
Any site with a kitchen or a ventilation system to look after, from a small pub to a hospital. We work with hotels, schools, care homes, offices, retail and leisure sites.
Is there a report after cleaning?
Yes, both a certificate and a report with photos. The report also suggests when the unit should next be inspected.
How much notice should we give?
It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and if it’s an emergency, call us any time.
How we price AHU cleaning
Sites vary more than people expect. The main factors:
- Whether several sites go on one quote
- How easy every part is to reach
- Where the site is and how we reach it
- Any permits to work or inductions
A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. You’ll have a fixed price before we start.
Asking for a quote
When you call or email, it’s useful to have:
- Detail shots of panels, filters and grilles
- Your last certificate, test record or report
- Photos showing the whole system and its surroundings
- The site address and the type of premises
Getting a quote doesn’t take long. Send a few details and pictures, and we typically reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.

Honest limits
AHU cleaning can’t fix everything, and we’d rather say so up front. It does not solve:
- A system that’s undersized for the building
- Controls and BMS settings that run the unit
- Faulty motors, drives or bearings
If in doubt, phone us on 0345 646 2711 or use the quote form and we’ll say what we think before you book.
What the work covers
- Dampers and louvres
- Internal panels
- Heating and cooling coils
- Filter sections
- Drain trays
- Supply and extract fans
For landlords and multi-site operators
Records are where multi-site compliance often slips. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We can quote either party and send the paperwork to whoever needs it.
Between visits
Looking after the system between visits is straightforward, and it helps at the next visit:
- Plan the next inspection before the last report gets filed away
- Stick to the filter change plan
- Make sure condensate is draining away
- Report stiff or damaged access doors
The ducts served by the unit may need attention too. Cleaning the unit and ducts together gives the best result, and we can survey both.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.
When to call us in Chatham Green
It matters for two reasons: the unit supplies the air people breathe, and a dirty unit has to work harder. For the people using the building every day, that is the air they breathe for hours on end.
It’s time to book a visit if you see:
- Debris and leaves in the fresh air intake
- Blocked condensate drains and slimy trays
- Air handling units due a clean after building work
- Air handling units with blocked filters
Healthcare buildings such as Broomfield Hospital, about 2.9 miles south, depend on their ventilation; if you manage a surgery, clinic or care home near Chatham Green, yours matters too.
