How we handle extract fan cleaning in Old Coulsdon
Grease on a fan isn’t spread evenly. Uneven build-up unbalances the impeller, leading to vibration, noise and strain on the motor and bearings. Cleaning the impeller and housing puts that right. The work covers fan housings, discharge points and roof-mounted fans, and people most often call us about less air being pulled from the kitchen and a fan that hums, whines or rumbles.
Across London, many commercial kitchens are squeezed into basements and narrow back-of-house spaces, and the duct may run up through several floors before it discharges at the roof. For a kitchen in Old Coulsdon, that normally means a longer system to clean and more access panels to plan around.
For insurers and inspectors, the record counts. That’s why every job is written up in a report with photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

How the visit works
Everything the job needs comes with us, from protective sheeting to tools and access equipment. All we need from you is clear access and the right equipment switched off. On site, the work takes an hour or two for most single fans. We fit London jobs around the building rather than the other way round, so a visit in Old Coulsdon is usually out of hours.
- Diagnosis first: we look for grease, noise and vibration.
- With the fan isolated, the housing is opened.
- Each blade is cleaned so the impeller runs evenly.
- Housing, outlet and the area around the motor are cleaned.
- We run the fan and note its condition in the photo report.
How to prepare

Aftercare tips
Good habits slow the build-up between visits. A few tips:
- Never cook with a filter missing
- Keep records of every fan clean
- Report rattles or humming early
- Look for grease stains near the discharge
You get before and after photos of the impeller and housing. It lists what was cleaned and anything we couldn’t reach, along with the recommended next clean date.
Listen to the fan. Rattles, hums or shaking can be early signs of build-up or wear, and catching it early keeps it a cleaning job.
Fixed quotes for extract fan cleaning in Old Coulsdon
Sites vary more than people expect. The main factors:
- How big the system is
- Access, including roofs, risers and ceiling voids
- Site rules, permits and inductions
- One-off work versus a regular cycle
Several systems or sites on one quote often makes better use of the time. Mention every system or site you need covered, and you’ll get one fixed quote.
Asking for a quote
Photos let us diagnose from a distance. Try to include:
- The times we could work without disrupting the site
- Any previous report or certificate
- Detail shots of panels, filters and grilles
- The postcode and the type of business
Quotes are quick. Call or email with a few details and you will usually have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
Why deal with it now?
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. Shared walls, risers and roofs mean a problem at one London site seldom stays put.
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 the price is fixed before work begins.

Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. Just call 0345 646 2711, or send details by email with your opening times and we will plan around them.
How do you handle parking and loading in Old Coulsdon?
Tell us where a van can stop near your site in Old Coulsdon, and about any building rules on loading. If the building has a loading slot system, we’ll book into it.
What types of premises do you cover?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.
Does a TR19 kitchen extract clean cover the fan?
Yes, a full TR19 clean includes the fan. If a fan can’t be reached, the report says so, so you always know what was cleaned.
Can you clean the fan on its own?
Yes, where it makes sense. A coated fan often means the duct before it is coated too, but the choice is yours.
What happens if you cannot reach some of it?
Anything we cannot reach goes on the report, with a note of where it is, and we tell you what would make it reachable, for example new access panels.

Yes. Our technicians work in Old Coulsdon, within the South East and London area we cover.
Who is responsible for fire safety on the premises?

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.
Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.

When to call us in Old Coulsdon
A fan in Old Coulsdon builds up grease at a rate set by the kitchen, not the location: daily hours and the amount of frying and grilling. BESA guidance sets minimum intervals of 3, 6 or 12 months for the whole system by daily use.
Keep an eye out for any of the following:
- Grease escaping from the fan outlet
- Rough running from the extract fan
- An extract fan with no cleaning record
- A motor area thick with grease
