Kent · Extract fan cleaning
Extract fan cleaning in Otford, Kent
Extract fan cleaning for businesses, landlords and public buildings in Otford. BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease.
- Weak extraction at the canopy
- A heavily greased fan housing
- A fan that has never been cleaned
Looking after it afterwards
Results last longer with the right care. We suggest:
- Check filters are seated before cooking
- Watch for grease marks around the outlet
- Keep access to the fan clear
- Book the fan into every full TR19 clean
The area around the fan is left clean, with waste grease removed. Wherever the fan is, the area around it is cleaned down.
Fewer grease particles reaching the fan means less build-up. Clean, well-seated filters are the fan’s first protection, and replace any that are damaged.
Extract fan cleaning for kitchens and businesses in Otford
The fan is cleaned as part of every full TR19® Grease clean, but a fan can also need attention on its own, for example when it’s noisy or vibrating. Where only the fan is cleaned, the report says so. We’re often asked to deal with rough running from the extract fan and less air being pulled from the kitchen, on in-line fans, roof-mounted fans and centrifugal fans.
Size doesn’t change the work: a kitchen in a place like Otford gets the whole system cleaned, canopy to discharge. The visit is booked around your opening hours, and the journey is planned ahead.
Insurers, fire officers and environmental health officers all look at records. That is why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

What staff can safely do
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
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 don’t reach the grease that builds up further in. That part needs specialist access and equipment.
Why it’s worth doing now in Otford
Grease on the fan is grease in the system. TR19® Grease covers the whole extract, fan included and many insurers require the full system to be cleaned to TR19. A quieter site near Otford still needs its system looked after.
What you pay depends on the size of the system, what state it’s in and how easy it is to reach. You get a fixed price before any work starts, so you know where you stand.

Landlords, agents and facilities managers
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 each one has its own record.
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
Your questions about extract fan cleaning in Otford
Can you work in Otford outside opening hours?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Otford needn’t be disturbed. When you ring 0345 646 2711 or email us, mention when the site is quiet.
Can you clean school kitchen extracts in Otford during the holidays?
Yes, out-of-term visits are normal for schools. The FSA’s register shows about 11 schools and colleges with food registrations within roughly a mile and a half of Otford. Booking early in the term gives the best choice of holiday dates.
Is TR19 a legal requirement?
No, not in itself. Insurers, fire officers and EHOs look to TR19® as the benchmark, and many insurance policies ask for proof of TR19® cleaning. The law behind it is the Fire Safety Order 2005 in England and Wales.
Are you accredited?
We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.
What does extract fan cleaning cost?
Size, condition, access and working hours all affect the cost. Call for a fixed quote and we’ll typically reply within one working day.
What do you need from me for a quote?
Some pictures and a quick description of the system, with the address and opening hours. If we need more, we’ll ask.
Do you offer emergency callouts?
Yes. Our emergency line runs 24/7 for anything that cannot wait until a planned visit. Call us any time and explain what’s happened.
What if parts of the system cannot be reached?
They’re marked on the report. In ductwork, new access panels are often the answer, which we can install.
What we are called out for in Otford
How fast a fan gets greasy in Otford depends on the cooking: daily hours and the amount of frying and grilling. Under BESA guidance, the whole system, fan included, needs cleaning at least every 3, 6 or 12 months depending on daily hours.
Common reasons sites call us are:
- A fan that has never been cleaned
- A fan that hums, whines or rumbles
- An extract fan that vibrates or rattles
- A fan coated in grease inside its housing
If you run a café or takeaway near Otford station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits.
Questions to ask before you book
- When the next visit should be, and why
- Whether VAT is included
- Whether the price is fixed
- What records you will receive afterwards

Otford kitchens: local notes
Food Standards Agency records list about 8 restaurants, cafés and canteens and about 5 takeaways and sandwich shops within about 1.5 miles of central Otford. Any of those kitchens with a canopy relies on a fan that gathers grease as it runs. Kitchens in Otford get their food hygiene inspections from Sevenoaks council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Keeping each certificate and photo report on file helps show the extract is looked after. Otford is covered by Kent Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
For schools such as Otford Primary School, kitchen extract cleaning is typically booked for the holidays, when the canteen is closed. If you run a church or community hall kitchen, near Church of St Bartholomew or elsewhere in Otford, its extract still collects grease from every lunch and event.
