FAQs for Bromley
Can you clean school ventilation in Bromley during the holidays?
Yes, and it’s the easiest time to do it. The FSA’s register shows about 70 schools and colleges with food registrations within roughly a mile and a half of Bromley. Tell us your holiday dates and we’ll book the visit for when the site is empty.
What do you need to know about parking in Bromley?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Much of our London work is done overnight, which helps.
How do you keep the site clean during the work?
With sheeting and covers, before anything else happens. The work is kept contained and leave the area clean.
Which sectors do you work in?
All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. Work is timed around how each site runs.
Will you repair the fan or motor?
Our AHU work is cleaning rather than mechanical repair. Any faults we notice are recorded for your maintenance team to follow up.
Does the AHU have to be shut down for cleaning?
Yes. The fan must be stopped and the unit isolated, so we plan it for a time that suits the building.
Can you quote from pictures?
In many cases, yes. With good photos, the site type and your last report, we can price many jobs. Where we cannot see enough, we arrange a survey.
Are you insured?
Yes. We carry full insurance, and we’ve been trading since 2009.
AHU cleaning for kitchens and businesses in Bromley
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. We look at the unit first, from photos or a site visit, and send you a fixed quote, so you know where you stand. If you have plant that has been serviced but not cleaned and units needing a clean before a new tenant or handover, we can put it right, from filter sections, heating and cooling coils and drain trays onwards.
London offices and flats often have ductwork added through successive refits, leaving sections that are hard to reach and seldom cleaned. In Bromley, as elsewhere, cleaning starts with an inspection of what’s there.
Think of the report as the 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.

In-house cleaning or a specialist?
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We’ll take a look and send you a fixed quote.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
AHU cleaning around Bromley
Going by the FSA’s register, there are about 70 schools, colleges and universities, about 53 care, childcare and hospital premises and about 15 hotels and guest houses serving food in Bromley and the streets around it, up to about 1.5 miles out. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. Bromley’s nearest hospital, St Clement's Hospital, is about 0.5 miles west. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes. Getting kit to a London plant room normally means lifts, stairs and an agreed loading slot.
School buildings such as St Agnes RC Primary School are typically done in the holidays, so classrooms aren’t disturbed. If you run a surgery, dental practice or care home near Bromley, clean ventilation matters as much to you as to a hospital like St Clement's Hospital (about 0.5 miles west).
Bromley is about 2 miles east of Whitechapel, in Greater London. Sites in Bromley get the same service as everywhere we cover: diagnosis first, a fixed price, out-of-hours working where necessary and a written report with photos. Bromley is one of 764 towns, villages and districts in Greater London where we work for commercial clients.

When something else is needed
To be straight with you, there are a few things this work will not fix:
- Breakdowns that need a mechanical engineer
- Problems with the unit’s controls or sensors
- Ductwork downstream of the unit, which is a separate clean
If in doubt, give us a ring on 0345 646 2711 or use the quote form and we’ll say what we think.
Where we work
- Filter sections
- Internal panels
- Supply and extract fans
- Drain trays
- Dampers and louvres
- Heating and cooling coils
Keeping the system healthy
To keep the system working properly between visits:
- Keep filter changes on time and recorded
- Watch for drips or damp patches near the plant
- Book the next check in line with the report
- File each AHU report in the maintenance log
Photos in the report cover the filters, coils, drain tray, fan and casing, along with anything we couldn’t reach. It also notes faults we spotted, such as damaged panels or a blocked drain.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
What happens if it’s left?
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. A booked night’s work in Bromley costs you no trading time; an unplanned closure does.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re unsure, call 0345 646 2711, or send details by email for straight advice and a fixed quote.

What affects the cost of AHU cleaning
A fixed price needs a few facts first. We look at:
- Working hours and out-of-hours timing
- Whether several sites go on one quote
- The size of the system
- Where the site is and how we reach it
The price reflects the work, not guesswork. That is why every job is surveyed first, and why the quote is fixed before we start.
Asking for a quote
We can often survey from pictures. Try to include:
- Your last certificate, test record or report
- Photos showing the whole system and its surroundings
- Where the site is and what kind of site it is
- Problems your staff have spotted

What we do, step by step
At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and the same goes into the written report. All told, the work takes from a few hours for a compact unit to a day or more for a large one. Security desks and permits-to-work are routine in London, so let us know what your building in Bromley needs from us.
- We survey the unit from pictures or on site and agree what’s included.
- The unit is shut down with your site team and the area protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- We clean out the drain tray and make sure it drains.
- We close up the unit and send the certificate and before and after photos.
Getting ready for the visit
