AHU cleaning in Baffins
A cooling coil drips condensate into a tray that should drain away. When the drain blocks, water sits there and the tray turns slimy, in the airstream that feeds the building. Clearing and cleaning the tray is central to every AHU clean. If you’re dealing with debris and leaves in the fresh air intake and units that have only ever had filter changes, we can put it right.
Smaller buildings around Baffins often keep their ventilation units in a roof void or plant cupboard, out of sight and easy to overlook. Filters, coils and drain trays need attention whatever the size of the unit.
Think of the report as the system’s health record: a dated account with pictures of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

Managing agents and facilities teams in Baffins
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we are happy to quote for all of it.
Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.

Staff cleaning versus specialist work
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
Baffins buildings and their air
Food Standards Agency records list about 31 schools, colleges and universities, about 33 care, childcare and hospital premises and about 3 hotels, B&Bs and guest houses registered as food businesses in Baffins and the streets around it, up to about 1.5 miles out. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. Baffins’s nearest hospital, St Mary's Hospital, is about 0.6 miles south-west. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.
If you manage a school such as Langstone Junior Academy, ventilation cleaning is best booked for the holidays. Hospitals such as St Mary's Hospital (about 0.6 miles south-west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Baffins are no different.

Your questions about AHU cleaning in Baffins
Is Baffins within the area you cover?
Yes. Baffins is within the area we cover across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can the work in Baffins be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. Your opening times are the first thing we ask for.
Do you offer maintenance contracts?
Yes. We run scheduled maintenance contracts, set at the interval the system needs. The report from each visit recommends the next date.
What happens to the waste?
We contain it and take it with us. We collect grease, debris and waste water as we go, so it does not spread.
What should I send you?
A short description and a few photos, with the address and opening hours. We will ask for anything else we need.
Which kinds of sites do you work on?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.
How much does AHU cleaning cost in Baffins?
We don’t publish prices, because the cost depends on the job: the size of the system, its condition, access and when we can work. We fix the price before we start.
How long does an AHU clean take?
Expect it to take from a few hours for a compact unit to a day or more for a large one. Size, layout and how dirty it is decide the rest, and the quote will give you a clear idea.
Between visits
After the visit, a few habits help the work last:
- Diary the inspection date recommended in the report
- Report water on the plant room floor
- Do not store bins or materials near the intake
- Store the TR19 paperwork where auditors can find it
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.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air instead of leaving it to guesswork.
Why act early in Baffins
A slimy drain tray only gets worse. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Clearing it now is a much smaller job. Around Baffins, a kitchen or building out of action is missed straight away.
The price reflects the work, not guesswork. That is why every job is surveyed first, and why the quote is fixed before work begins.

The process
Our technicians bring everything the work needs, including protection sheets, the right tools and access kit. You only need to give us clear access and switch off what needs to be off. On site, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. Tell us when your site near Baffins is quiet and the visit will be booked for then.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Preparing for the visit
- Make sure someone can let us in and lock up afterwards
- Tell us about site rules, permits or sign-in
- Mention any locked doors, roof access or ceiling voids
Get a fixed quote
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.

What affects the cost of AHU cleaning
Your quote is based on your site. We take into account:
- One-off work versus a regular cycle
- How easy every part is to reach
- Whether several sites go on one quote
- Travel, parking and unloading
Combining work into one visit or one programme can make for a more efficient booking. Tell us about everything you’d like looked at and we will price it together.
Asking for a quote
A few details help us quote accurately. When you get in touch, it helps to send:
- The roof, plant room or outside wall the system runs to
- Close-ups of filters, grilles, hatches or access panels
- Where the site is and what kind of site it is
- Any previous report or certificate
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
