How we handle extract fan cleaning in Wennington
Duct Doctor has been cleaning kitchen extract fans since 2009. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’re fully insured, with CHAS, SafeContractor and ISO 9001. We are often asked to deal with thick grease on the impeller and casing and a fan shaking on its mounts, on in-line fans, centrifugal fans and roof-mounted fans.
In London, few kitchens can spare a day to close, so extract cleaning in Wennington is usually done overnight, after the last service. Before the clean, we agree loading, parking and roof access with whoever manages the building.
Good records are part of the job. You get a written report with pictures after each visit, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

FAQs for Wennington
Which council inspects kitchens in Wennington?
Food hygiene inspections in Wennington are carried out by Havering council. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Which fire service covers Wennington?
That is London Fire Brigade. TR19® isn’t law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
Can you look after several sites?
Yes. We work across South East England and London, so sites at different addresses can be planned together on one programme. Each site gets its own report and photos.
What’s the cleaning interval for an extract fan?
Daily cooking hours set the minimum, under BESA guidance. At the extremes, that is 3-monthly for heavy use and 12-monthly for light use, fan included.
Do you offer maintenance contracts?
Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. The report from each visit recommends the next date.
What makes a kitchen extract fan vibrate?
An unbalanced impeller, normally from uneven grease, is a common cause. We clean the fan and tell you if anything else, like worn bearings, is to blame.
Are you insured?
Yes. We carry full insurance and have been trading since 2009.
Who is responsible for fire safety on the premises?
Under the Regulatory Reform (Fire Safety) Order 2005, it’s the responsible person: normally the employer or whoever controls the premises. Landlords, facilities managers and managing agents can also hold responsibility.
What affects the quote in Wennington
The diagnosis comes before the price. The main factors are:
- Any permits to work or inductions
- Where the site is and how we reach it
- The number of sites or systems
- One-off work versus a regular cycle
What you pay depends on how big the system is, what state it’s in and access to every part of it. You get a fixed price before work begins, so you know where you stand.
What we need to know
When you contact us, these details help:
- The paperwork from the last visit, if you have it
- Problems your staff have spotted
- The roof, plant room or outside wall the system runs to
- When the site is open and when it’s quiet
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. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
Extract fan cleaning in Wennington: the local picture
The FSA’s food hygiene register shows about 23 restaurants, cafés and works canteens and about 16 takeaways within about 1.5 miles of central Wennington. Where they cook under a canopy, an extract fan is pulling grease-laden air through its blades every service. Wennington is covered by London Fire Brigade. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel. Overnight is the normal time to clean a London kitchen extract, so trading isn’t affected.
Bursars and site managers at schools such as Brady Primary School tend to book extract cleaning for when the kitchen is empty. Rainham Hall, about 1.5 miles north-west, is one of the historic houses near Wennington; if you run event catering at a venue like that, cleans can be booked between functions. Volunteers running a hall kitchen near St Mary and St Peter's Church, or anywhere in Wennington, may not know when the extract was last cleaned, and a grease test settles it.

What else we do in Wennington
Staff cleaning versus specialist work
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
What extract fan cleaning can’t fix
We’d rather tell you now than book work that won’t help, so these are the things it won’t cover:
- Damaged fan blades
- A faulty speed controller or isolator
- Grease in the duct and canopy before the fan (those need a full TR19 clean)
Not sure which it is? You can phone us on 0345 646 2711 or drop us a line and we’ll tell you honestly.
What the work covers
- Axial fans
- Fan housings

How the job changes from site to site
Kitchens with long cooking hours
When a busy kitchen’s fan fails, cooking stops. A clean fan is less likely to strain, and our 24/7 emergency callout is there if it happens anyway.
Fan housings and motors
We clean around the motor without soaking its electrics, and the fan is isolated throughout. Grease on and around the motor can trap heat, so the surrounding area is cleaned carefully.
What we do, step by step
On the day, we arrive 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 an hour or two for one fan, longer when it’s hard to reach. Many London buildings have a managing agent, a security desk or a permit-to-work system, so tell us who to contact in Wennington.
- Diagnosis first: we look for grease, noise and vibration.
- With the fan isolated, the housing is opened.
- The impeller is cleaned blade by blade so it runs balanced.
- We clean the casing, the outlet and around the motor.
- The fan goes back into service with a report on its condition.
Before we arrive
- Let us know about parking and loading
- Allow time for equipment near the work to be turned off and cool down
- Move anything stored near the system

For landlords and multi-site operators
We also work for facilities teams across offices, schools and healthcare across Greater London. Larger estates can be phased building by building to keep disruption down.
If you look after several sites, we can schedule visits across all of them on one quote. Each site gets its own report and pictures, so each one has its own record.
Aftercare tips
How long the results last depends on use and care. Here’s what we suggest:
- Keep records of every fan clean
- Run the extract throughout cooking
- Notice when the fan starts to sound different
- Don’t store items in front of the fan’s access point
File the photo report with your other extract records. It shows the fan’s condition at the time of the clean, which helps if anything changes later.
A change in how the fan sounds is worth noting. Rattles, hums or shaking can be early signs of build-up or wear and early action can save a repair.
