Do you need extract fan cleaning in Belsize?
A fan in Belsize builds up grease at a rate set by the kitchen, not the location: 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.
Most sites get in touch when they notice something like this:
- Weak extraction at the canopy
- A fan shaking on its mounts
- A fan coated in grease inside its housing
- Grease stains around the discharge
Term dates shape school work: for a school like Sarratt Church of England Primary School, an extract clean fits neatly into a half-term or summer break.
What your quote should include
- Whether the whole system is included, or only the parts that are easy to reach
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- Whether the price is fixed
- How areas they cannot reach will be recorded
Extract fan cleaning in Belsize
If the extract fan in Belsize has become noisy, weak or greasy? A few details or a photo help when you ring 0345 646 2711, or email photos, and you will get a fixed price, normally within one working day. If you have grease around the motor and its mounts and a fan that no longer moves enough air, we can put it right, from roof-mounted fans, fan housings and axial fans onwards.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, where grease settles in the flat sections. Access, parking and timings are agreed before the day.
The report is your system’s health record: a dated account with photos of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

Belsize questions
Can the work in Belsize be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. That way a site in Belsize does not have to lose a day’s trading. When you give us a ring on 0345 646 2711 or email us, mention when the site is quiet.
Do you cover smaller places like Belsize?
Yes. Belsize is within the area we cover across London and the South East. Photos of the system and directions to the site help us plan the visit.
Are you accredited?
We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.
What happens if you cannot reach some of it?
We never leave them off the paperwork. The report says which parts couldn’t be reached and why, and we can quote to improve the access.
How do you protect the area?
Floors and surfaces near the work are sheeted before work begins, and waste is contained as we go. Before we leave, we tidy up and clean down.
How much does extract fan cleaning cost?
The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote, normally ready within one working day.
Which kinds of sites do you work on?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.
How far ahead should we book?
For planned work, earlier is better, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
What the work involves, part by part
Kitchens with long cooking hours
Kitchens that cook 12 to 16 hours a day put the most grease through their fans. BESA guidance sets at least 3-monthly cleaning for that level of use, fan included.
Roof-mounted fans
On a roof, the air is cooler and grease drops out faster. The impeller and housing are scraped and degreased.
Keeping the system healthy
Aftercare is simple, and it helps at the next visit:
- Make sure the fan is included each time
- Listen for new noises or vibration from the fan
- Check filters are seated before cooking
- File the fan’s report with your other records
Keep the report with the maintenance log and fire risk assessment. It shows the fan’s condition at the time of the clean, which helps if anything changes later.
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.
What we do, step by step
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes a few hours where there are several fans or heavy deposits. Somewhere as small as Belsize, the date and timings are agreed with you well before the day.
- First we check the fan’s condition and how it sounds.
- Once isolated, we open the fan up.
- 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.
Getting ready for the visit
- Tell us the best time to work, such as after service or at a weekend
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Plan for cooking equipment or plant to be off before we arrive

Advice
What affects the cost of extract fan cleaning
Every site gets its own quote. This is what makes a difference:
- Where the site is and how we reach it
- How easy every part is to reach
- When the work can happen, such as evenings, overnight or weekends
- The size of the system
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account and give you a fixed price before work begins.
What to send for a quote
What to send for a quote:
- When the site is open and when it’s quiet
- Close-ups of filters, grilles, hatches or access panels
- Any previous report or certificate
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
There’s no standard price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, and then send you a fixed quote. To get going, phone us on 0345 646 2711 or email us.
Belsize kitchens: local notes
The Food Standards Agency lists about 7 bars, pubs and nightclubs as registered food businesses within about 1.5 miles of central Belsize. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. Food hygiene inspections in Belsize are the job of Three Rivers council’s environmental health team. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Before-and-after pictures from each clean are a simple way to show the extract is in hand. Belsize is covered by Hertfordshire Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.
Historic houses near Belsize, such as Chenies Manor House about 2 miles south-west, are a reminder that older buildings with event kitchens can have long, awkward duct routes. A hall kitchen that only cooks for events, whether near Church of St Paul or elsewhere in Belsize, still needs its extract cleaned, just less often.
