AHU cleaning in Cuddington, done properly
Where a building in Cuddington 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. If you are dealing with coils clogged with dust and debris and rooms that smell stuffy when the system runs, we can put it right, from filter sections, internal panels and drain trays onwards.
Somewhere as small as Cuddington, ducted ventilation is usually limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

What staff can safely do
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.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.

Your questions about AHU cleaning in Cuddington
Is Cuddington within the area you cover?
Yes, we work in villages as well as towns, and Cuddington is covered. Just mention lanes, gates or anything else about the site when you book.
Can the work in Cuddington be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. It means the site in Cuddington keeps running as normal. When you give us a ring on 0345 646 2711, or email photos, mention when the site is quiet.
How long does it take to clean an air handling unit?
Typically the clean takes anything from half a day for one small unit to several shifts for a plant room full of them. We plan the shutdown around that, including evenings or weekends.
What if parts of the system cannot be reached?
They’re listed in the report, never skipped quietly. The report says which parts couldn’t be reached and why, along with a quote to put access in.
Will you repair the fan or motor?
The clean includes noting faults, but repairs sit with your maintenance contractor, with pictures where it helps.
What information do you need?
The site address, the type of premises and your opening hours, plus photos of the system and your last certificate or report if you have one.
Are you accredited?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.
Which sectors do you work in?
All kinds of commercial and public premises: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. Work is timed around how each site runs.
Part by part
Filters
Filter condition tells you a lot about the rest of the unit. We photograph them for the report.
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. We clean the coil and the tray beneath it together.
Leave it or put it right?
Leave an AHU uncleaned and the dirt doesn’t stay put. It’s carried through the ductwork and out of the grilles, which is why the unit and the ducts are best cleaned together. With notice, the visit to Cuddington can be fitted around your bookings and events.
Combining work into one visit or one programme often makes better use of the time. Mention every system or site you need covered and we will price it together.

What we do, step by step
We start by comparing what we find with the survey or your photos. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. For a village or hamlet like Cuddington, tell us about narrow lanes, gates and parking when you book.
- First the unit is surveyed, from pictures or a visit, and the scope agreed.
- We arrange the shutdown with your staff and sheet the area.
- Filters, coils, fan section and casing are cleaned in turn.
- Drain trays are cleared and cleaned and the outlet checked.
- We close up the unit and send the certificate and before and after photos.
Before we arrive
- Arrange a key holder or contact on site
- Find the previous report, if there is one
- Let us know about parking and loading
Get a fixed quote
To get a fixed quote, call 0345 646 2711, or email photos and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. You will normally have a quote within one working day.
Advice
How we price AHU cleaning
We do not publish a price list, because no two systems are the same. What we look at:
- The size of the system
- Site rules, permits and inductions
- Where the site is and how we reach it
- Whether it’s a one-off visit or part of a schedule
When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account, and the price is fixed before work begins.
What we need to know
There’s no need for technical detail. Just send:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Any access panels or hatches you can see
- A few general shots of the system
We don’t publish a price list, because every site is different. We look at your system first, from photos or on a visit, and then send you a fixed quote. To get going, call us on 0345 646 2711 or use the quote form.
Ventilation in Cuddington buildings
Food Standards Agency records list about 18 schools, colleges and universities and about 30 caring premises (care homes, nurseries and hospitals) registered as food businesses in and around Cuddington, up to about a mile and a half out. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. At about 11 miles from central London, Cuddington sits well inside the area we cover. A survey and a fixed quote come first, then the visit at a time that suits you. For Cuddington, the closest hospital is St. Anthony's Hospital, roughly 1.6 miles north. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.
Workplaces around Cheam station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts. If you run a surgery, dental practice or care home near Cuddington, clean ventilation matters as much to you as to a hospital like St. Anthony's Hospital (about 1.6 miles north).

Common problems we fix in Cuddington
Most units live out of sight on roofs, in plant rooms or in ceiling voids and are rarely seen by anyone but maintenance staff. It’s easy for a long time to go by without anyone opening the panels.
Common reasons sites call us are:
- Drain trays holding standing water
- Intake sections clogged with outdoor debris
- Dirty fans and fan housings
- Dirty coils holding back the airflow
For schools like Nonsuch High School for Girls, the holidays are the usual time to inspect and clean ventilation.
Comparing quotes
- How VAT is shown on the quote
- Whether the work can be done while the site is closed
- Whether inaccessible sections are listed on the report
- Which accreditations they hold, and whether you can check them
For landlords and multi-site operators
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 the report can go to both.
Running several sites is easier with one contractor. We cover South East England and London, so a run of sites can go into one programme and kept on a regular cycle.
