What your team can do, and what needs us
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We’ll take a look and give you a fixed quote.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That is our job.
About our extract fan cleaning in Harvel
Kitchen extract fans come in different forms: roof-mounted units, inline fans within the duct, and wall fans. The way in depends on the type, and we plan that during the survey. Common call-outs are for a fan motor running hot under a coat of grease and grease escaping from the fan outlet, on fan housings, centrifugal fans and axial fans.
In a small place like Harvel, kitchens are often in older or extended buildings, with long single-storey duct runs, and those horizontal sections are where grease settles. We agree access and timings in advance.
Every visit ends with a written report and photos, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Harvel kitchens: local notes
Food Standards Agency records list about 6 restaurants, cafés and works canteens across Harvel and its immediate surroundings (about a mile and a half). Any of those kitchens with a canopy relies on a fan that gathers grease as it runs. In Harvel, food businesses are inspected by environmental health officers from Gravesham council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A dated certificate in the maintenance file answers the question before it’s asked. The fire and rescue service for Harvel is Kent Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
School kitchens, at schools like Culverstone Green Primary School for example, are typically cleaned in the holidays so no lunches are lost. A hall kitchen that only cooks for events, whether near Church of Our Lady of the Meadow or elsewhere in Harvel, still needs its extract cleaned, just less often.

What’s near Harvel
Locally, jobs take us to businesses close to Meopham School and Trosley Country Park. For rail, the closest station is Sole Street station, about 2.7 miles north of the centre.

What happens on the day
Our technicians bring everything the work needs, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. On site, the work takes an hour or two for one fan, longer when it’s hard to reach. Somewhere as small as Harvel, the date and timings are agreed with you well before the day.
- 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.
- 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
- Agree a time when the area can be out of use
- Clear loose items from the work area
- Make sure someone can let us in and lock up afterwards

When to call us in Harvel
Grease condenses as the air cools, and on a roof or outside wall the fan can be in some of the coolest air in the system. So grease often settles heavily there.
Look out for these warning signs:
- An extract fan that vibrates or rattles
- A fan that has never been cleaned
- Grease escaping from the fan outlet
- Thick grease on the impeller and casing
If you run catering at a historic house or estate in the area (Cobham College is about 3.4 miles north-east), event kitchens in older buildings often have awkward duct runs that need planning.

What affects the cost of extract fan cleaning
There’s no set price list, because sites vary so much. The quote depends on:
- The scale of the work
- Where the site is and how we reach it
- Access, including roofs, risers and ceiling voids
- The condition we find in the survey
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you’re unsure, phone us on 0345 646 2711, or email photos and we’ll give you an honest view and a fixed quote.
Helping us quote
You don’t need the technical terms. It helps if you can send:
- The times we could work without disrupting the site
- Any access panels or hatches you can see
- The roof, plant room or outside wall the system runs to
- Any symptoms, from odd noises to smells or leaks
For a fixed quote, call us on 0345 646 2711, or send details by email and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. We usually come back within one working day.
Why act early in Harvel
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. If the system at a site near Harvel fails, there may be nowhere nearby to move to.
Combining work into one visit or one programme often makes better use of the time. Mention every system or site you need covered, and you’ll get one fixed quote.

Questions from Harvel
Can the work in Harvel be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. It means the site in Harvel keeps running as normal. Your opening times are the first thing we ask for.
Can school kitchens in Harvel be cleaned in the holidays?
Yes, and it’s the easiest time to do it. With about 3 schools and colleges on the FSA’s register within roughly a mile and a half of Harvel, it pays to plan holiday dates ahead. Send us your term dates when you phone us on 0345 646 2711 or send us an email, and we will fit the work in.
Is Harvel in your area?
Yes. We work across Greater London, Surrey, Kent, Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, Harvel included.
What makes a kitchen extract fan vibrate?
A common cause is grease. Uneven build-up on the blades throws the fan off balance, causing vibration and noise. If cleaning does not, the bearings or motor may need attention.
How often does the fan need cleaning?
It’s cleaned with the whole extract, from every 3 months for 12 to 16 hours of cooking a day to every 12 months for 2 to 6 hours. Readings may show it needs cleaning more often.
Do we need to close while you work?
Not normally. We need the work area to ourselves while we’re on site, so we book a time when it would be closed anyway.
Can you set up regular visits?
Yes. Tell us what you have and how it’s used and we will propose a schedule with a fixed quote.
Who has the legal duty for fire safety?
The law calls them the responsible person. It’s normally the employer, or whoever controls the building, and in shared buildings more than one person can have duties. Your lease and fire risk assessment should make it clear.
