What AHU cleaning cannot fix
We won’t sell you work that does not address the problem, so these are the things it won’t cover:
- The supply and extract ducts, quoted separately
- Controls and BMS settings that run the unit
- Mechanical faults with motors, belts or bearings
If in doubt, phone us on 0345 646 2711, or send details by email and we’ll say what we think before booking.

AHU cleaning for kitchens and businesses in Hampstead Norreys
Where a building in Hampstead Norreys has had little more than filter changes, there may be dirt on the coils, fan and casing that nobody has looked at. A full AHU clean takes in the whole unit. Common call-outs are for condensate trays that won’t empty and air handling units with blocked filters, on supply and extract fans, dampers and louvres and drain trays.
For a building in or near Hampstead Norreys, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
The report is your system’s health record: dated, with photos, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

What affects the quote in Hampstead Norreys
We do not publish a price list, because no two systems are the same. What we look at:
- A single visit or a regular plan
- Site rules, permits and inductions
- Whether we need access equipment or extra panels
- The scale of the work
Several systems or sites on one quote often makes better use of the time. Mention every system or site you need covered, and you will get one fixed quote.
Asking for a quote
To speed up the quote, please include:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Photos showing the whole system and its surroundings
- The times we could work without disrupting the site
- Any access panels or hatches you can see

What happens on the day
There are three stages on the day: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with photos. The middle part takes longest, and that takes a single shift for a typical unit, longer for large or heavily soiled ones. Somewhere like Hampstead Norreys, lanes, gates and parking are worth mentioning in advance.
- We survey the unit from photos or on site and agree what’s included.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Standing water and slime come out of the tray and the drain is checked.
- We close up the unit and send the certificate and before and after pictures.
Preparing for the visit
- Tell us the best time to work, such as after service or at a weekend
- Dig out any earlier paperwork for the system
- Clear the space around the work

Advice
AHU cleaning in Hampstead Norreys: local notes
Hampstead Norreys is about 49 miles from central London, well within the area we cover across London and the South East. We work evenings, overnight and at weekends, so the visit fits around the site. About 5.8 miles south-west of Hampstead Norreys is West Berkshire Community Hospital, the nearest hospital. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.
Healthcare ventilation, from large hospitals like West Berkshire Community Hospital (about 5.8 miles south-west) to small clinics, depends on clean filters, coils and ducts.
Hampstead Norreys is about 6 miles north of Thatcham, in West Berkshire. Wherever you are in the RG18 postcode area, we can carry out AHU cleaning at your premises. Hampstead Norreys is one of 155 towns, villages and districts in West Berkshire we cover for commercial clients. Our Reading page covers sites nearby (12 miles or so).
Our technicians cover all of RG18 for AHU cleaning and the roads nearby. Whether your site is on Church Street, Scottalls Lane and Forge Hill or a nearby road, we can help.

Different parts, different methods
Rooftop and plant room units
Smaller units in ceiling voids are part of the work as well. We protect the area below before opening them.
Fans and fan sections
Every bit of air passes the fan, so a dirty fan sends dirt downstream. The impeller, its housing and the fan chamber are cleaned.
What your team can do, and what needs us
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Hampstead Norreys questions
Can you come to Hampstead Norreys after we close?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in Hampstead Norreys needn’t be disturbed. Let us know the hours you are closed and we’ll book within them.
Can you do AHU cleaning in Hampstead Norreys?
Yes. We work across London and the South East, and Hampstead Norreys is part of that. Get in touch with the details and we’ll arrange a survey.
Is there a report after cleaning?
Yes, a TR19® certificate and a photo report. The report also suggests when the unit should next be inspected.
Which parts of an air handling unit do you clean?
Filters, coils, drain trays, the fan and the internal surfaces are all covered. What happens to the filters is agreed when we quote.
What happens to the waste?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. None of it is left on site.
Can you clean the ducts connected to the AHU?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. Cleaning the unit and ducts together often makes sense, and we can quote for both.
What accreditations do you have?
We hold CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
How do you protect the area?
We start with protection: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.
Between visits
Good habits slow the build-up between visits. Our tips:
- Look at the condensate drain whenever the unit is serviced
- Store the TR19 paperwork where auditors can find it
- Report water on the plant room floor
- Don’t ignore odours coming through the grilles
Restart the unit with your site team or maintenance contractor once we’ve finished. Keep an eye on the condensate drain over the next few days to make sure it stays clear.
Make sure access doors and panels on the unit open easily. Sections that are awkward to open are the ones that get skipped.
Signs you need AHU cleaning in Hampstead Norreys
Wherever there’s a cooling coil, there’s condensate. If the drain tray outlet blocks or the tray doesn’t fall properly, water stands in it, and that’s where slime and odours start.
Most sites get in touch after spotting something like this:
- Rooms that smell stuffy when the system runs
- Dirty coils holding back the airflow
- Units needing a clean before a new tenant or handover
- Plant that has been serviced but not cleaned
School buildings such as Hampstead Norreys C.E. Primary School are normally done in the holidays, so classrooms are not disturbed.
Questions to ask before booking
- Whether a written report and pictures are included
- What hours they’ll be on site
