Multi-site and managed buildings
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
Whether it’s one building or many, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
AHU cleaning in Totteridge, done properly
Units vary a lot in size, age and layout, whether it’s a compact unit in a ceiling void or a big unit on the roof. Every job starts with a survey, from pictures or on site, followed by a fixed quote, so you know where you stand. Common call-outs are for air handling units never cleaned inside and intake sections clogged with outdoor debris, across supply and extract fans, heating and cooling coils and dampers and louvres.
London buildings often depend on air handling units in plant rooms or on the roof to supply fresh air. In a building in Totteridge, dust and debris build up in the units and ductwork over time, which is what TR19® Air cleaning deals with.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

Questions from Totteridge
How do you handle parking and loading in Totteridge?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Where restrictions apply in the day, an evening or overnight visit usually gets round them.
Do you work overnight in Totteridge?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in Totteridge needn’t be disturbed. Tell us your opening hours when you ask for a quote.
How long will the unit be out of action?
The work takes half a day to a full day per unit, with large plant planned over several shifts. Bigger units can be phased, so call 0345 646 2711, or email photos to talk it through.
Will the ventilation be off while you clean?
Yes. The fan must be stopped and the unit isolated, and we time the work to suit the site.
What do you need from me for a quote?
Some pictures and a quick description of the system plus the address and your hours. If we need more, we will ask.
Do you clean the ductwork as well?
Yes. We clean supply and extract ductwork to TR19® Air as well. Cleaning the unit and ducts together often makes sense, and we can quote for both.
What do you do with what you remove?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. We don’t leave it behind.
Is a quote from photos possible?
Often, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Larger or hidden systems need a survey on site first.
What your team can do, and what needs us
Staff cleaning and specialist work are not 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.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We can diagnose it and quote.
Common problems we fix in Totteridge
Whatever surrounds a building in Totteridge, the air drawn into its AHU carries dust, pollen and debris. Most of it lands at the intake and the first stage of filters, and some travels further into the unit.
Clients usually contact us after spotting something like this:
- Rooms that smell stuffy when the system runs
- Plant that needs cleaning after a refit
- Air handling units with blocked filters
- Dirty fans and fan housings
Healthcare ventilation, from large hospitals like Barnet General Hospital (about 1.3 miles north-west) to small clinics, depends on clean filters, coils and ducts.
What your quote should include
- Whether the quote is based on a survey or photos
- How areas they can’t reach will be recorded
- Exactly which parts of the system are covered
- Whether they recommend a next date
How the job changes from site to site
Filters
Filter condition tells you a lot about the rest of the unit. We photograph them for the report.
Fans and fan sections
The fan moves all of the unit’s air, so dirt on it gets spread around. We clean the impeller, housing and surrounding section.
What happens if it’s left?
Facilities teams are often asked for evidence that the ventilation is looked after. Our certificate and photo report give you clear evidence, for audits, tenants or your own peace of mind. London sites work long hours, and the longer a job is left, the bigger it gets.
The cost depends on how big the system is, what state it’s in and access to every part of it. You get a fixed price before any work starts, so there are no surprises.

- We are fully insured
- Accredited under CHAS and SafeContractor, with ISO 9001

What AHU cleaning looks like in Totteridge
The FSA’s food hygiene register lists about 23 schools, colleges and universities and about 32 care, childcare and hospital premises with registered kitchens or food service across Totteridge and its immediate surroundings (about a mile and a half). Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Ventilation cleaning in London buildings is usually planned for evenings or weekends. Barnet General Hospital is the nearest hospital, about 1.3 miles north-west of Totteridge. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital.
Classrooms and halls at schools such as The Totteridge Academy are easiest to work in when pupils are away.
