Ductwork cleaning in Netherne on-the-Hill

Not every duct has enough access panels. TR19 calls for any section we couldn’t reach to be recorded, and new panels can be fitted to reach it in future. An honest report beats a guess. Typical jobs include fat dripping from the ductwork and stale grease odours from the duct, on bends and junctions, horizontal duct runs and vertical risers.

Across London, many commercial kitchens are squeezed into basements and narrow back-of-house spaces, with extract ducts that can climb several floors to discharge at roof level. In Netherne on-the-Hill, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.

Think of the report as the system’s health record: dated, with pictures, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

What your team can do, and what needs us

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.

Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.

Netherne on-the-Hill questions

Do you work at weekends in Netherne on-the-Hill?

Yes, we can come after you close and finish before you open. The site is handed back ready to open. Tell us your opening hours when you ask for a quote.

Which fire service covers Netherne on-the-Hill?

That is London Fire Brigade. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.

Who is responsible for fire safety on the premises?

In the words of the Fire Safety Order 2005, it’s the responsible person. That’s generally the employer or the person in control of the premises, and in shared buildings more than one person can have duties. Your lease and fire risk assessment should make it clear.

How long does ductwork cleaning take?

It depends on the length of the duct, the number of access panels and how much grease there is. As a guide, it takes from a few hours to more than one visit, depending on duct length and access.

Do I get a certificate for ductwork cleaning?

Readings, photos and, for a full clean, a TR19 certificate. The report says when the next clean is due.

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 cleaning to TR19® is the recognised way to show grease is under control.

What information do you need?

A short description and a few pictures, with the address and opening hours. If we need more, we will ask.

How much does ductwork cleaning cost?

We do not publish prices, because the cost depends on the job: how big it is, what state it’s in, how we reach it and the working hours. You get a fixed price before we start.

Kitchen extracts in Netherne on-the-Hill

Food Standards Agency records include about 5 pubs and bars within about 1.5 miles of central Netherne on-the-Hill. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Kitchens in Netherne on-the-Hill get their food hygiene inspections from Reigate and Banstead council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A TR19® certificate and photo report after each clean gives you a record to show an inspector. London Fire Brigade covers Netherne on-the-Hill. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.

Signs you need ductwork cleaning in Netherne on-the-Hill

Damaged or poorly fitted filters let more grease into the duct. The duct then takes grease that the filters should have stopped, and build-up speeds up.

Most sites get in touch after spotting one of these:

  • Sections of duct with no access panels
  • An insurer asking for TR19 evidence
  • A rancid smell from the extract duct
  • Thick deposits at the bottom of a vertical duct

Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Netherne on-the-Hill is St Lawrence's Hospital, about 1.9 miles east.

Our hiring checklist

Why deal with it now?

Booking the duct clean in Netherne on-the-Hill now keeps it a planned job. The work takes a few hours for a short run, longer for long runs and tall risers, and we work evenings, overnight and weekends. A busy site in Netherne on-the-Hill builds up dirt and wear quickly, so putting it off makes the eventual job larger.

One small site or a whole estate, the quote is built the same way: the work involved, the access and the timing. You’ll have a fixed price before work begins.

What you get with us

  • Out-of-hours work and a 24/7 emergency line
  • Every visit written up, with pictures
  • BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease
  • Fixed quotes, normally within one working day

What the work involves, part by part

Vertical risers

In taller buildings, a riser may pass through several floors and fire compartments, so fire dampers may be fitted where it crosses them. Damper testing is a separate service.

Bends and transitions

The join where the canopy meets the duct is a common hotspot. We reach it from the plenum side where possible.

For landlords and multi-site operators

Facilities teams in offices, schools and healthcare sites book us too in Netherne on-the-Hill and across Greater London. Larger estates can be phased building by building to keep disruption down.

Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.

Aftercare tips

Aftercare is simple, and it helps at the next visit:

  • Report any grease dripping from duct joints
  • Diarise the next duct clean
  • Ask us about extra access panels where sections cannot be reached
  • Do not block access panels with shelving or stock

The report gives a recommended next clean date, based on the readings and your daily cooking hours, in line with BESA guidance.

Run the extract the whole time the kitchen is cooking. Moving air carries vapour through rather than letting it settle, so switching off early adds to the build-up.

How it works

Everything the job needs comes with us, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. On site, the work takes a few hours for a short run, longer for long runs and tall risers. Getting kit into a London building takes planning, so let us know where we can load and park in Netherne on-the-Hill.

  1. Diagnosis: a survey of the duct’s route, size and access.
  2. A fixed quote follows, based on what we found.
  3. We clean section by section, working from panel to panel.
  4. Bends, risers and the base of each riser get extra attention.
  5. Readings, photos and a recommended next clean date complete the job.

Before we arrive

  • Tell us where we can park and unload
  • Tell us the best time to work, such as after service or at a weekend
  • Mention any sign-in, permit or induction we need

Getting a quote

Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before any work starts.
