About our extract fan cleaning in Riverhead
Grease on a fan is not spread evenly. Heavier deposits on some blades throw the impeller off balance, leading to vibration, noise and strain on the motor and bearings. Cleaning the impeller and housing puts that right. If you are dealing with a motor area thick with grease and fat spreading onto the roof or wall by the fan, we can put it right.
In a smaller place like Riverhead, the kitchens with extract systems are more likely to be a pub, a café, a takeaway or a school or care home kitchen than a big restaurant. Quieter kitchens still collect grease in the duct, just more slowly, so cleaning is planned around how much it cooks and what the readings show.
Every visit ends with a written report and pictures, 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.

Why act early in Riverhead
A greasy fan has to work harder to move the same air. Airflow at the canopy drops and the kitchen gets hotter and smokier, while the motor runs under more strain. You choose the date of a planned visit, and a breakdown never asks.
No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.

Do you need extract fan cleaning in Riverhead?
A fan collects more grease when the filters let more through. Missing, damaged or badly fitted filters let grease travel the whole system, so the fan takes far more than it should.
Signs it’s time to call us include:
- A fan shaking on its mounts
- Less air being pulled from the kitchen
- Thick grease on the impeller and casing
- Hot, greasy smells near the fan
If you run catering at a healthcare site, such as a hospital like Sevenoaks Hospital about 1.1 miles east, the extract may need cleaning more often than a part-time kitchen.

Riverhead questions
Is Riverhead within the area you cover?
Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.
Can school kitchens in Riverhead be cleaned in the holidays?
Yes, holiday work suits schools best. With about 14 schools and colleges on the FSA’s register within roughly a mile and a half of Riverhead, it pays to plan holiday dates ahead. Send us your term dates when you call us on 0345 646 2711 or email us, and we will fit the work in.
Is there a survey before the work?
Yes, every time. We diagnose before we treat: the survey shows what needs doing and what access we need, and the quote is based on that.
Which kinds of sites do you work on?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, plus food production and leisure sites.
Will we have to shut during the visit?
Typically not. Booking the work out of hours means the site can carry on as normal. Bigger sites can be done in stages to keep things running.
Do you offer extract fan cleaning separately?
Yes, we do. We record it as a fan-only clean, so your TR19 records stay accurate. The whole system still needs cleaning at the intervals in BESA guidance.
What happens to the waste?
It’s contained and taken away. Grease, debris and waste water are collected as the work goes on, so it doesn’t spread.
Can you come out in an emergency?
Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.
Riverhead kitchens: local notes
Look up Riverhead on the FSA’s food hygiene register and you will find about 54 restaurants, cafés and canteens and about 20 takeaways within roughly a mile and a half of the centre of Riverhead. Any of those kitchens with a canopy relies on a fan that gathers grease as it runs. Environmental health officers from Sevenoaks council inspect food businesses in Riverhead. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Fire safety in Riverhead falls to 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.
If you look after a school kitchen, at a school such as Amherst School or anywhere near Riverhead, the holidays are the usual time for a TR19® clean. A kitchen near Sevenoaks station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval.

What affects the quote in Riverhead
Your quote is based on your site. We consider:
- Site rules, permits and inductions
- How big the system is
- Parking and loading at the site
- Access, including roofs, risers and ceiling voids
You will not find a price list here, because the cost depends on the site in front of us. Call for a fixed quote, and we will talk you through it.
Asking for a quote
When you call or email, it’s useful to have:
- The roof, plant room or outside wall the system runs to
- Any access panels or hatches you can see
- Where the site is and what kind of site it is
- When the site is open and when it’s quiet
There’s no standard price list, because no two systems are the same. We look at your system first, from photos or on a visit, and then give you a fixed quote. To get going, call 0345 646 2711, or email photos.
Staff cleaning versus specialist work
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.

For landlords and multi-site operators
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we’re happy to quote for all of it.
Facilities teams in offices, schools and healthcare sites book us too across Kent. Larger estates can be phased building by building around the people who use them.
How it works
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 an hour or two for most single fans. Everything the job in Riverhead needs is worked out beforehand, from the survey.
- We locate the fan and plan how to reach and isolate it.
- It’s isolated so it can’t run while we work.
- Grease is scraped off the impeller blades and casing.
- Blades, housing and surrounds are degreased with care around the electrics.
- We reassemble, run and photograph the fan.
Before we arrive
- Plan for cooking equipment or plant to be off before we arrive
- Clear loose items from the work area
- Mention any locked doors, roof access or ceiling voids

Advice
Between visits
Aftercare is simple, and it makes the next visit easier:
- File the fan’s report with your other records
- Report grease escaping from the fan
- Notice when the fan starts to sound different
- Leave a clear route to the fan
Keep the report with the maintenance log and fire risk assessment. It gives a dated record of the fan’s condition, which helps if anything changes later.
Make sure the fan is reachable. A fan that can be reached safely is a fan that gets cleaned, whether it’s on a roof, in a ceiling or on a wall.
