AHU cleaning in Bagmore
The fan pushes every bit of air in the system, so dirt on the impeller and housing gets spread around. We clean the fan section along with the rest of the unit, once the unit has been shut down and isolated. Common call-outs are for filters that are clogged or overdue and dirty fans and fan housings, on internal panels, heating and cooling coils and filter sections.
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.
Good records are part of the job. You get a written report with pictures after each visit, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

What AHU cleaning looks like in Bagmore
Bagmore’s nearest hospital, Alton Community Hospital, is about 4.9 miles south-east. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients. Bagmore, about 46 miles from central London, is within our usual area. Evening, overnight and weekend visits are all possible.
Hospitals such as Alton Community Hospital (about 4.9 miles south-east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Bagmore are no different. Ventilation work in and around Bagmore is risk-based: inspect, then clean what needs it.

What happens on the day
Your trading hours come first. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes one overnight shift for many single units, with bigger plant phased. If the van will struggle with a lane or gateway near Bagmore, let us know and we will plan around it.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Preparing for the visit
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Let us know about permits to work or site inductions
- Arrange a key holder or contact on site

Related advice
Leave it or put it right?
Tenants, auditors and owners may want proof that the air handling plant is kept clean. A TR19® certificate and photo report give you that, for audits, tenants or your own peace of mind. In a small place like Bagmore, a system that fails can take a site out of use.
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. You will have a fixed price before we start.

How we price AHU cleaning
There’s no set price list, because no two systems are the same. The quote depends on:
- Site requirements such as sign-in and permits
- Working hours and out-of-hours timing
- Travel, parking and unloading
- How big the system is
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’re not sure what’s needed, phone us on 0345 646 2711, or send details by email and we will give you an honest view and a fixed quote.
What we need to know
There’s no need for technical detail. Just send:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The times we could work without disrupting the site
- A few general shots of the system
- Where the plant sits or the system leaves the building, such as a roof or outside wall
For a fixed quote, call 0345 646 2711 or drop us a line and tell us the type of site, your opening hours and roughly what the system looks like. A few photos and your last certificate or report help a lot. You’ll normally have a quote within one working day.
What a clean will not put right
To be straight with you, there are a few things this work won’t fix:
- Controls and BMS settings that run the unit
- Dirty ducts beyond the unit itself
- Faulty motors, drives or bearings
If in doubt, call us on 0345 646 2711 or drop us a line and we’ll say what we think before you book.
Parts of the system we cover

How the job changes from site to site
Filters
Filters are the first line of defence in the unit. We check them, and clean or change them as agreed in the quote, and clean the filter housing.
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. We clean them with care so the fins aren’t damaged.
Common questions in Bagmore
Can you come to Bagmore after we close?
Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. Let us know the hours you’re closed and we will book within them.
Do you offer AHU cleaning in Bagmore?
Yes, Bagmore is within the area we cover across London and the South East. A fixed quote usually follows within one working day of the survey details.
Can you look after several sites?
Yes. We work across South East England and London, so sites at different addresses can be planned together on one programme. Each site gets its own report and photos.
How much does AHU cleaning cost?
It depends on the site, so we quote each one individually. To get one, give us a ring on 0345 646 2711 or use the quote form and tell us about the site and its opening hours.
What happens to the waste?
It’s contained and taken away. Grease, debris and waste water are collected as the work goes on, so it doesn’t spread.
Can you quote from pictures?
Yes, where the photos show enough. Otherwise, we book a survey at a time that suits the site, and the quote follows that.
Which accreditations do you hold?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.
Can you come out in an emergency?
Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.

Aftercare tips
Results last longer with the right care. We suggest:
- Look at the condensate drain whenever the unit is serviced
- Watch for drips or damp patches near the plant
- Clear leaves and litter away from the intake
- Change filters on schedule and log each change
Photos in the report cover the filters, coils, drain tray, fan and casing, along with anything we couldn’t reach. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.
Managing agents and facilities teams in Bagmore
Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept to a regular schedule.
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 can quote for the whole system.
