In-house cleaning or a specialist?
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That’s our job.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
AHU cleaning for kitchens and businesses in Newnham
Think of an AHU clean as a full check-up for the ventilation. We look inside each section, clean what we find and record it with pictures, so the report shows exactly what was done. The work covers internal panels, filter sections and dampers and louvres, and common reasons people get in touch are air handling units never cleaned inside and leaves and litter drawn into the unit.
Somewhere as small as Newnham, 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.
The sign-off is always in writing: a written report, dated and illustrated with photos, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

What happens on the day
At the end of the visit, someone from your team can look over the work with us. 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 a single shift for a typical unit, longer for large or heavily soiled ones. Somewhere like Newnham, lanes, gates and parking are worth mentioning in advance.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- 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.
How to prepare
- Find the previous report, if there is one
- Let us know about parking and loading
- Let us know how we reach the system, including roofs, risers and plant rooms

What types of premises do you cover?
Any commercial site with kitchens or ventilation, from a small pub to a hospital. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
What information do you need?
Some pictures and a quick description of the system, with the address and opening hours. We’ll ask for anything else we need.
Are you insured?
Yes, fully. CHAS and SafeContractor accreditation sit alongside it, for sites that check contractor safety.
How much does AHU cleaning cost in Newnham?
It depends on the site, so we quote each one individually. To get one, give us a ring on 0345 646 2711 or email us and tell us about the site and its opening hours.
Do you have a 24/7 line?
Yes. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line, and we will advise on what to do next.
Do you work with multi-site operators?
Yes. Our area covers London and the South East, so we can schedule a run of sites as one programme. Every site has its own report.
How we price AHU cleaning
Every site gets its own quote. This is what makes a difference:
- Whether several sites go on one quote
- The times the site is available
- Any permits to work or inductions
- Access, including roofs, risers and ceiling voids
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you are unsure, phone us on 0345 646 2711, or email photos and we’ll give you an honest view and a fixed quote.
What we need to know
What to send for a quote:
- The paperwork from the last visit, if you have it
- A few general shots of the system
- The site address and the type of premises
- Any symptoms, from odd noises to smells or leaks
There’s no standard price list, because no two systems are the same. We look at your system first, from photos or on a visit, then send a fixed quote. To get going, give us a ring on 0345 646 2711 or send us an email.
For landlords and multi-site operators
We also work for facilities teams across offices, schools and healthcare across Hertfordshire. Work can be phased by floor, building or site to keep disruption down.
We regularly work with managing agents. Send the address, what’s needed and how access works and we’ll come back with a fixed quote.
Keeping the system healthy
Simple habits between visits make a real difference. Our advice:
- Make sure the unit’s access doors open easily
- Clear leaves and litter away from the intake
- Keep the certificate and photo report with the plant records
- Do not ignore odours coming through the grilles
The ducts served by the unit may need attention too. Cleaning the unit and ducts together gives the best result, and we can quote for both.
Do not let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.
When something else is needed
In fairness, there are a few things this work will not fix:
- Ventilation that was badly designed in the first place
- Ductwork downstream of the unit, which is a separate clean
- Damaged coils beyond cleaning
Not sure which it is? You can ring 0345 646 2711, or send details by email and we will tell you honestly before booking.
Parts of the system we cover
- Drain trays
- Supply and extract fans
- Internal panels
- Dampers and louvres
- Filter sections
- Heating and cooling coils

What happens if it’s left?
A clean unit feeds cleaner air into the ductwork, so the whole system stays cleaner for longer. That makes the next inspection of a building in Newnham simpler. Out of sight is the usual reason a rural system goes too long without attention.
A single site or a whole portfolio, the quote is built the same way: what needs doing, how we get to it and when. The price is fixed before any work starts.
