Ductwork cleaning in Farnborough: the local picture
There are about 39 cafés, restaurants and staff canteens and about 20 takeaways within 1.5 miles or so of the middle of Farnborough, according to the Food Standards Agency’s register. Each kitchen that cooks under a canopy sends grease-laden air into a duct, where it cools and settles. London Fire Brigade covers Farnborough. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. Food hygiene inspections in Farnborough are the job of Bromley council’s environmental health team. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Keeping each certificate and photo report on file helps show the extract is looked after.
For schools such as Farnborough Primary School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed. A hall kitchen that only cooks for events, whether near Church of St Giles the Abbot or elsewhere in Farnborough, still needs its extract cleaned, just less often.
Farnborough is about 2 miles south-west of Orpington, in Greater London.

Ductwork cleaning for kitchens and businesses in Farnborough
Duct cleaning is the hardest part of an extract clean, and the part most often skipped. Sections with no way in can go uncleaned for years. We open up every reachable section and record any we cannot reach, so you know exactly where you stand. The work covers vertical risers, horizontal duct runs and access panels, and the jobs we see most are years of grease along the duct floor and grease pooling at the foot of the riser.
London kitchens tend to trade late and open early, so work in Farnborough is normally booked for the night or the early hours. Parking, loading and access to the roof are agreed with the building before the night of the clean.
A written report with pictures follows every visit, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

What your team can do, and what needs us
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.
In-house cleaning and specialist cleaning do different jobs. 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.
When to call us in Farnborough
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.
Common reasons sites call us are:
- Smells of old cooking grease from the ductwork
- Fat dripping from the ductwork
- High readings at a recent grease test
- Proof of duct cleaning for the insurer
Healthcare kitchens, like those at hospitals such as Orpington Hospital (about 0.9 miles east), often cook for long hours, which puts them in BESA’s heavier-use bands.
What your quote should include
- If they look at the system before pricing
- Whether they’re fully insured
- Whether a written report and pictures are included
- Whether the quote shows VAT
Multi-site and managed buildings
For anyone managing more than one site, we can schedule visits across all of them on one quote. Every building has its own written report, so records stay tidy.
Running several sites is easier with one contractor. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.
Part by part
Attenuators and discharge
At the end of the duct is the discharge. It can gather grease and mark the wall or roof around it, so it’s cleaned as far as safe access allows.
Bends and transitions
Wherever the duct turns or changes size, grease builds up. Slowing air leaves grease behind, so these points get extra attention.
Fixed quotes for ductwork cleaning in Farnborough
We do not publish a price list, because no two systems are the same. The quote depends on:
- Site rules, permits and inductions
- The condition of the system
- Travel, parking and unloading
- One-off work versus a regular cycle
When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote and give you a fixed price before work begins.
Asking for a quote
Photos let us diagnose from a distance. Try to include:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Photos showing the whole system and its surroundings
- The site address and the type of premises
- The roof, plant room or outside wall the system runs to
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
Your questions about ductwork cleaning in Farnborough
Do you do school kitchen extract cleaning in Farnborough in the summer holidays?
Yes. The holidays are the usual time for school work. Food Standards Agency records list about 7 schools, colleges and universities with registered kitchens within about a mile and a half of Farnborough. Tell us your holiday dates and we’ll book the visit for when the site is empty.
How do you handle parking and loading in Farnborough?
A loading bay, a visitor permit or off-street space near the site in Farnborough makes the visit easier to plan. Where restrictions apply in the day, an evening or overnight visit normally gets round them.
What does ductwork cleaning cost?
There’s no set price, as it depends on the job: the size of the system, its condition, access and when we can work. We fix the price before any work starts.
How much notice should we give?
Book as early as you can for planned work, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.
When is the ductwork cleaned?
The duct is cleaned out of hours, evenings, overnight or at weekends. The extract and cooking equipment need to be off.
Are you fully insured?
Yes, we are fully insured. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.
How long will the duct clean 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 a few hours for a short run, longer for long runs and tall risers.
Do you cover Farnborough?
Yes. We work across Greater London, Surrey, Kent, Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, and that includes Farnborough.
What happens on the day
The first job on site is protection: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. The work on site takes a few hours for a short run, longer for long runs and tall risers, and we clear up before we go. Getting kit into a London building takes planning, so let us know where we can load and park in Farnborough.
- We trace the duct and find every way in.
- Grease thickness is measured at set points.
- Out of hours, the area is protected and the access panels opened.
- Thick grease is scraped out, then the runs and risers are degreased.
- We close up, re-test, photograph and record anything out of reach.
Before we arrive
- Dig out any earlier paperwork for the system
- Clear loose items from the work area
- Tell us where we can park and unload
Getting a quote
To get a fixed quote, give us a ring on 0345 646 2711, or email photos and tell us the type of site, your opening hours and roughly what the system looks like. A few photos and your last certificate or report help a lot. We usually come back within one working day.

Leave it or put it right?
There’s no law that names TR19. The Fire Safety Order 2005 makes the responsible person assess and reduce fire risk, including the grease inside the extract ductwork. Leaving it on a busy London site only adds to the work.
The price reflects the work, not guesswork. That is why every job is surveyed first, and why the quote is fixed before work begins.
