How we handle extract fan cleaning in South Hampstead
Kitchen extract fans come in different forms: roof-mounted units, inline fans within the duct, and wall fans. Each is isolated and opened in its own way, and we plan that during the survey. The work covers centrifugal fans, roof-mounted fans and fan housings, and the jobs we see most are a fan that has never been cleaned and an extract fan that vibrates or rattles.
Across London, many commercial kitchens are squeezed into basements and narrow back-of-house spaces, with extract ducts that can climb several floors to discharge at roof level. In South Hampstead, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we’re fully insured.

South Hampstead kitchens: local notes
There are about 625 restaurants, cafés and canteens and about 265 takeaways and sandwich shops in and around South Hampstead, up to about a mile and a half out, according to the Food Standards Agency’s register. Grease builds up on fan blades and housings in kitchens like these, unbalancing the impeller. Environmental health officers from Camden council inspect food businesses in South Hampstead. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Our report lists what was cleaned and when, which is useful to have ready. Most London extract cleaning happens at night, after the last service.
Church and community hall kitchens, near Church of All Souls or anywhere around South Hampstead, are easy to forget, but their extracts collect grease like any other. A hospital like Hospital of St John and St Elizabeth, about 0.7 miles south, is the kind of site where a kitchen may cook for patients, staff and visitors all day.

Why deal with it now?
A fan clean in South Hampstead does not take long: it takes a few hours where there are several fans or heavy deposits. Waiting adds vibration, wear and a harder clean. It’s better booked as a planned job in South Hampstead than handled as an emergency.
Combining work into one visit or one programme can make for a more efficient booking. Mention every system or site you need covered and we’ll price it together.

Keeping the system healthy
A little care between visits keeps the system in better shape. Our advice:
- Look for grease stains near the discharge
- Run the extract throughout cooking
- File the fan’s report with your other records
- Keep the grease filters clean and in place
If the fan needs more than a clean, we will say so plainly. Fan repair and replacement are services we offer too, so you have one point of contact.
Run the fan throughout cooking. Air that keeps moving carries vapour out rather than letting it settle, so keeping it running helps keep it clean.
Managing agents and facilities teams in South Hampstead
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and photos, so records stay tidy.
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side and send the paperwork to whoever needs it.
When something else is needed
An honest diagnosis matters more to us than a booking, so here’s what extract fan cleaning will not do:
- Damaged fan blades
- A motor that has burnt out
- A dirty duct upstream of the fan
Not sure which it is? You can phone us on 0345 646 2711, or email photos and we’ll tell you honestly before you book.

FAQs for South Hampstead
Who would carry out a food hygiene inspection at a kitchen in South Hampstead?
That’s Camden council, whose environmental health officers carry out food hygiene inspections in South Hampstead. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
Do you clean school canteen extracts around South Hampstead out of term?
Yes, out-of-term visits are normal for schools. Around South Hampstead, the Food Standards Agency lists about 70 schools and colleges with registered kitchens within a mile and a half or so. Booking early in the term gives the best choice of holiday dates.
How often does the fan need cleaning?
At least as often as the rest of the extract, which BESA guidance sets by daily cooking hours: from 3-monthly for heavy use to 12-monthly for light use. A noisy or heavily coated fan may need it sooner.
How much does extract fan cleaning cost?
There’s no set price, as it depends on the job: how big it is, what state it’s in, how we reach it and the working hours. We fix the price before work begins.
Will we have to shut during the visit?
Not usually. We need the work area to ourselves while we are on site, so the visit goes in a quiet slot.
Do you cover South Hampstead?
Yes. We cover South Hampstead and across Greater London, within our South East and London area. To book, ring 0345 646 2711, or send details by email.
Who is responsible for fire safety on the premises?
The law calls them the responsible person. That is generally the employer or the person in control of the premises, and in shared buildings more than one person can have duties. Your lease and fire risk assessment should make it clear.
Are you accredited?
Our accreditations are CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
Staff cleaning versus specialist work
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
The process
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes an hour or two for most single fans. Before any visit in South Hampstead, we agree where the van can stop and how equipment reaches the system.
- First we locate the fan and agree how it’s safely isolated.
- The fan is isolated so it can’t start while we work.
- The impeller and the housing around it are scraped clean.
- We degrease the fan and housing, taking care around the motor.
- It’s closed up, run and checked, and photos go into your report.
How to prepare
- Move anything stored near the system
- Mention any parking or loading restrictions
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
Ask for a quote
Every quote begins with a look at the system, either from photos 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.

- A noisy fan that has got louder over time
- Thick grease on the impeller and casing
