London: your questions answered
Do you clean school canteen extracts around London out of term?
Yes. The holidays are the usual time for school work. Around London, the Food Standards Agency lists about 93 schools and colleges with registered kitchens within a mile and a half or so. You can ring 0345 646 2711 or use the quote form with the dates the site is empty.
Who enforces fire safety at workplaces in London?
It’s London Fire Brigade, which covers London. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
What paperwork do I get after a fan clean?
Every clean has a photo report, with anything we noticed. For a full TR19 clean, you also get a certificate through the BESCA Vent Hygiene Elite portal.
What do you do with what you remove?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. We don’t leave it behind.
Why is my extract fan noisy?
Uneven grease on the impeller often causes it. We clean the fan and tell you if anything else, like worn bearings, is to blame.
Do you offer extract fan cleaning separately?
Yes, we can clean just the fan. It’s useful when a fan is noisy or greasy between full cleans, but it doesn’t replace a full TR19 clean.
Can you come out in an emergency?
Yes. Our emergency line runs 24/7 for anything that cannot wait until a planned visit. Ring any time and tell us what’s happened.
What types of premises do you cover?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, plus food production and leisure sites.
Extract fan cleaning in London
Think of the fan as the system’s heart and the grease as a clot. A greasy fan works harder and moves less air. Our job is to clear it, check it runs smoothly and record what we found so you get a clean bill of health. We’re often asked to deal with fat spreading onto the roof or wall by the fan and grease around the motor and its mounts, across discharge points, roof-mounted fans and fan housings.
In London, extract cleaning fits around service: after the last cover, before breakfast or on a day the kitchen is shut. Sites with more than one kitchen can be cleaned in phases.
Think of the report as the system’s health record: a dated account with pictures of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

Kitchen extracts in London
Food Standards Agency records include about 431 bars, pubs and nightclubs and about 102 hotels and guest houses within roughly a mile and a half of the centre of London. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Fire safety in London falls to 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. Kitchens in London get their food hygiene inspections from Southwark council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Keeping each certificate and photo report on file helps show the extract is looked after.
A hall kitchen that only cooks for events, whether near St George the Martyr or elsewhere in London, still needs its extract cleaned, just less often. A hospital like Surrey Dispensary, about within half a mile south-east, is the kind of site where a kitchen may cook for patients, staff and visitors all day.

Leave it or put it right?
Grease on the impeller makes the fan less efficient. Less air is pulled from the kitchen, so heat and smoke linger and the motor works harder. For a site in London with several systems, a planned schedule stops everything falling due at once.
One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. The price is fixed before any work starts.

Aftercare tips
A little care between visits keeps the system in better shape. Our advice:
- Watch for grease marks around the outlet
- Keep each photo report with the maintenance log
- Do not store items in front of the fan’s access point
- Tell us if the extract feels weaker
The area around the fan is left clean, with waste grease removed. On a roof or outside wall, we leave the surrounding area tidy.
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.
When to call us in London
The fan sits at the end of the grease’s journey. The grease that is left lands on the blades and the casing, and the spinning blades fling it onto the walls of the housing.
Look out for these warning signs:
- Burning smells from the fan area
- Less air being pulled from the kitchen
- Vibration from an unbalanced impeller
- Grease escaping from the fan outlet
A kitchen near Elephant & Castle station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval.
What to look for in a quote
- Whether the quote is based on a survey or pictures
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- Whether the work can be done while the site is closed
- Whether inaccessible sections are listed on the report
What happens on the day
We are used to working while the site is closed. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. The visit itself takes a few hours where there are several fans or heavy deposits. Whoever holds the keys and signs off contractors at your site in London is the person we need to speak to before the day.
- First we locate the fan and agree how it’s safely isolated.
- With the fan isolated, the housing is opened.
- We remove the grease from the blades, impeller and casing.
- The fan and its surrounds are degreased, keeping clear of the motor’s electrics.
- We reassemble, run the fan and photograph the result.
Getting ready for the visit
- Mention any locked doors, roof access or ceiling voids
- Allow time for equipment near the work to be turned off and cool down
- Make sure someone can let us in and lock up afterwards
Get a fixed quote
Every quote begins with a look at the system, either from pictures and details you send or from a site visit. After that, you get a fixed price for the work so you know the cost before work begins.
Advice
Managing agents and facilities teams in London
Running several sites is easier with one contractor. We cover South East England and London, so a run of sites can go into one programme and kept on a regular cycle.
Whether it’s one building or many, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Different parts, different methods
Wall fans
Grease can mark the outside wall around the fan. The outlet is checked as well as the fan.
Fan housings and motors
Some fans use a belt drive. We clean around them and note any wear for your records.

What affects the quote in London
Before we fix a price, we need to know a few things. We check:
- Any permits to work or inductions
- The size of the system
- How many systems or sites are involved
- Whether it’s a one-off visit or part of a schedule
The price reflects the work, not guesswork. That’s why every job is surveyed first, and the price is agreed before we start.
What to send for a quote
To speed up the quote, please include:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Wide photos of the system and the area around it
- The paperwork from the last visit, if you have it
- Any access panels or hatches you can see
To help us quote: the address, the type of site and when it’s open, a few pictures and any previous report or certificate. Then give us a ring on 0345 646 2711, or send details by email.
