How we handle ventilation duct cleaning in Pratt's Bottom
Beyond the kitchen, TR19® Air covers the ordinary supply and extract systems that serve offices, schools and other buildings. It works by inspecting first and cleaning where the risk calls for it, so every job starts with a look inside the ducts. We are often asked to deal with duct runs that can’t be reached for cleaning and ductwork that hasn’t been inspected, across grilles and diffusers, toilet extract systems and general extract ductwork.
Many London buildings have had their ventilation extended and altered through several fit-outs, leaving sections that are hard to reach and seldom cleaned. In Pratt's Bottom, as elsewhere, cleaning starts with an inspection of what’s there.
Accreditations are easy to claim and worth checking. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

For landlords and multi-site operators
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
Records are where multi-site compliance often slips. Each visit ends with a dated report and pictures, ready to show insurers, fire officers or EHOs.
Aftercare tips
So the system stays in good health:
- Don’t block grilles with furniture or storage
- Tell your facilities team about dirty diffusers
- Keep the TR19 certificate and photo report in the maintenance log
- Watch for water stains around grilles
We recommend when the system should next be inspected, in line with the risk-based approach of TR19® Air. Put it in the diary now so it doesn’t slip.
Good filter maintenance protects the ductwork. Overdue or badly fitted filters let dust into the supply ducts.
Part by part
Hospitals and care homes
In care settings, keeping dust contained is a priority. We protect the work area and take everything away.
Offices and retail
Offices and shops tend to need the work done outside opening hours to keep the space open.
What your team can do, and what needs us
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We’ll take a look and send you a fixed quote.

How we price ventilation duct cleaning
There’s no set price list, because sites vary so much. What we look at:
- Site rules, permits and inductions
- Whether several sites go on one quote
- The condition we find in the survey
- How easy every part is to reach
No two sites are the same, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.
Helping us quote
Before you ask for a quote, gather:
- Any access panels or hatches you can see
- The roof, plant room or outside wall the system runs to
- Any symptoms, from odd noises to smells or leaks
- The site address and the type of premises
The quickest way to a quote is to send pictures: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and we can price many jobs without a visit.
What happens on the day
Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and the same goes into the written report. The visit takes a shift or two for a small system, longer for a whole building. For a job in Pratt's Bottom, tell us about loading bays, permits, lifts and roof access when you book.
- First we plan when the work can happen, often out of hours.
- Access panels are opened along each run.
- We photograph the ducts, then clean each section in turn.
- We clean the grilles and diffusers and put them back.
- We take after pictures and send the certificate and report.
How to prepare
- Dig out any earlier paperwork for the system
- Agree a time when the area can be out of use
- Clear loose items from the work area
How to get a quote
Quotes are quick. Call or email with a few details and you will normally have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
Advice
Pratt's Bottom: your questions answered
Do you clean school ventilation in Pratt's Bottom in the holidays?
Yes. Half-terms and the summer break are the natural time for school work. With about 3 schools and colleges on the FSA’s register within roughly a mile and a half of Pratt's Bottom, it pays to plan holiday dates ahead. Booking early in the term gives the best choice of holiday dates.
How do you handle parking and loading in Pratt's Bottom?
A loading bay, a visitor permit or off-street space near the site in Pratt's Bottom makes the visit easier to plan. Night visits tend to make loading easier on London streets.
Do you cover Pratt's Bottom?
Yes. We cover Pratt's Bottom and across Greater London, within our South East and London area. To book, call 0345 646 2711 or email us.
Which kinds of sites do you work on?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, as well as food production and leisure sites.
Will we have to shut during the visit?
Not typically. Out-of-hours visits keep the disruption down. Bigger sites can be done in stages to keep things running.
What is TR19® Air?
TR19® Air is the part of BESA’s TR19® that covers general supply and extract ventilation, rather than kitchen extract. It’s risk-based and led by inspection, while TR19® Grease covers kitchen extract systems.
Does the law say we must follow TR19?
No. TR19® is BESA’s specification, not legislation. The law is the Regulatory Reform (Fire Safety) Order 2005, which makes the responsible person assess and reduce fire risk, and cleaning to TR19® is the recognised way to show grease is under control.
What do you do to protect the area?
We cover floors and nearby surfaces with sheeting before any work starts, and waste is contained as we go. At the end, the area is cleaned down.
What a clean will not put right
We’d rather tell you now than book work that will not help, so here are the limits:
- Damp or mould problems coming from the building fabric
- Building management settings that run the plant
- Leaking or broken duct sections
Not sure which it is? You can phone us on 0345 646 2711 or send us an email and we’ll tell you honestly.
