When to call us in Adelphi
Refits and building work send dust into ventilation systems, particularly if it’s left running while work goes on. Plaster, wood and masonry dust can sit in the ducts for years.
What we are most often called out for:
- Blocked general extract ductwork
- Duct runs that can’t be reached for cleaning
- Dusty supply ductwork that hasn’t been cleaned in years
- Systems with no record of inspection or cleaning
For schools like St Clement Danes CofE Primary School, the holidays are the usual time to inspect and clean ventilation.
Before booking anyone
- What insurance they carry
- If the quote is a fixed price or an estimate
- Whether inaccessible sections are listed on the report
- Whether the work can be done while the site is closed
Ventilation duct cleaning in Adelphi
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 we look before we clean. The work covers hospitals and care homes, supply ductwork and toilet extract systems, and the jobs we see most are toilet and washroom extracts full of fluff and odours carried round the building by the ducts.
Across London, offices, hotels, schools and healthcare buildings rely on mechanical ventilation, much of it supplied through air handling units on roofs or in basements. In a building in Adelphi, dust and debris build up in the units and ductwork over time.
The sign-off is always in writing: a dated report with pictures of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

Adelphi buildings and their air
Food Standards Agency data includes about 83 schools, colleges and universities, about 47 hospitals, care homes and childcare premises and about 243 hotels, B&Bs and guest houses within 1.5 miles or so of the middle of Adelphi. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Getting kit to a London plant room typically means lifts, stairs and an agreed loading slot. About within half a mile north-east of Adelphi is Savoy Hospital, the nearest hospital. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
Hospitals such as Savoy Hospital (about less than half a mile north-east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Adelphi are no different. Workplaces around London Charing Cross station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts.
Adelphi is about 1 mile south-east of Marylebone, in Greater London. Across the W1D area, we can take on ventilation duct cleaning. Our area takes in 764 places across Greater London, from busy centres to quieter spots.

Different parts, different methods
Extract ductwork
Toilet and washroom extract can carry moisture as well as dust, which makes dirt stick. We clean them and note any damp or corrosion.
Supply ductwork
We check supply ducts at intervals along each run before deciding what to clean.
Looking after it afterwards
Good habits slow the build-up between visits. Our tips:
- Watch for water stains around grilles
- Book the next inspection on the date the report recommends
- Keep filters changed on time
- File each ventilation report with the building records
What was cleaned is listed, along with any parts that weren’t accessible, backed up by before and after photos. If access panels are needed, we’ll say where.
Do not let construction dust into the ventilation by turning it off or covering the openings.
Why it’s worth doing now in Adelphi
An inspection-led approach avoids cleaning ducts that don’t need it. Skipping it leaves you guessing. A busy site in Adelphi builds up dirt and wear quickly, so putting it off makes the eventual job larger.
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account and give you a fixed price before work begins.

How the visit works
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool first, and the area around the work is covered and protected. On site, it takes a shift or two for a small system, longer for a whole building. Loading bays, visitor permits and roof access are the first things we ask about for a site in Adelphi.
- First we check the layout and any past paperwork.
- We inspect the ducts at chosen points to see where cleaning is needed.
- We cover the area below and turn off the system.
- Ducts, grilles and diffusers are cleaned and the debris taken away.
- We report on the work, listing any inaccessible sections and the next inspection date.
Getting ready for the visit
- Arrange a key holder or contact on site
- Let us know about parking and loading
- Agree a time when the area can be out of use

FAQs for Adelphi
Can you come to Adelphi after we close?
Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. Just give us a ring on 0345 646 2711 or send us an email with your opening times and we’ll plan around them.
Does London parking affect a job in Adelphi?
A loading bay, a visitor permit or off-street space near the site in Adelphi makes the visit easier to plan. If the building has a loading slot system, we’ll book into it.
What does TR19 mean?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t legislation, but it’s the standard people check against.
When should our ventilation next be cleaned?
There’s no single interval; under TR19® Air, inspection decides. We suggest a next inspection date after every visit.
What happens to the waste?
Anything we remove is contained as we work and taken away with us, including grease, debris and dirty water. We do not leave it behind.
Is TR19 cleaning required by law?
No. TR19® itself is not law; it’s a BESA specification. The law is the Regulatory Reform (Fire Safety) Order 2005, which makes the responsible person assess and reduce fire risk, and TR19® is the benchmark for showing that grease in the extract is under control.
Do you work in Adelphi?
Yes. We cover Adelphi and the rest of Greater London, within our South East and London area. To book, ring 0345 646 2711 or use the quote form.
What happens if parts of the ductwork can’t be reached?
Nothing is hidden: any section we couldn’t get into is listed. Access panels can be added where necessary.
Multi-site and managed buildings
Facilities teams in offices, schools and healthcare sites book us too in Adelphi and across Greater London. Larger estates can be phased building by building to keep disruption down.
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements and we’ll come back with a fixed quote.
When it’s something else
Before you book, it helps to know what’s not included:
- Damp or mould problems coming from the building fabric
- Grease in kitchen extract systems, cleaned to TR19® Grease instead
- Ducts that are damaged, corroded or leaking and need replacing
If you’re not sure, just ring 0345 646 2711, or send details by email and we’ll give you a straight answer.
