Extract fan cleaning in Forest Hill
If the ducts are the arteries, the fan is the heart. A heart under strain works harder for less. Our job is to clear it, check it runs smoothly and record what we found, before signing it off. Typical jobs include a fan left out of previous cleans and hot, greasy smells near the fan, on centrifugal fans, fan housings and discharge points.
In a village or hamlet like Forest Hill, the kitchens that need extract cleaning are usually a pub, a school, a care home or a hall kitchen, wherever there is one. Each still has a canopy and duct that collect grease, whatever the size of the place.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

In-house cleaning or a specialist?
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.

How the job changes from site to site
Roof-mounted fans
Roof fans also discharge grease onto the roof around them, so the outlet area is checked too. We note any grease around the fan.
Fan housings and motors
We clean around the motor without soaking its electrics, and the fan is isolated throughout. Grease on and around the motor can trap heat, so we clean what we safely can.
Your questions about extract fan cleaning in Forest Hill
Which environmental health team covers Forest Hill?
Food hygiene inspections in Forest Hill are carried out by South Oxfordshire council. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Can you get to a site in Forest Hill?
Yes, Forest Hill is part of our area, however small the site. Photos of the system and directions to the site help us plan the visit.
Who is the responsible person?
That depends on who controls the premises. Under the Fire Safety Order 2005, it’s the responsible person, which may be the employer, owner, landlord, facilities manager or managing agent.
Do we need to close while you work?
Not usually. We need the work area to ourselves while we are on site, so the visit goes in a quiet slot.
Do you survey before quoting?
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.
What happens if you cannot reach some of it?
They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
Can you set up regular visits?
Yes. Scheduled maintenance plans are part of what we do, with visits at the interval your system needs. Each report recommends when the next visit should be.
What if the fan needs more than a clean?
A fan that needs repair is noted on the report, with what we found. We offer extract fan repair and replacement, and there’s a 24/7 emergency callout for breakdowns.
Why deal with it now?
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. A planned visit to Forest Hill is easier to arrange than an emergency callout.
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 the price is fixed before we start.

When it’s something else
In fairness, there are a few things this work won’t fix:
- An impeller that is bent or split
- Grease in the duct and canopy before the fan (those need a full TR19 clean)
- A faulty speed controller or isolator
If in doubt, give us a ring on 0345 646 2711 or drop us a line and we’ll say what we think before you book.

Kitchen extracts in Forest Hill
Look up Forest Hill on the FSA’s food hygiene register and you’ll find about 3 restaurants, cafés and canteens and about 3 takeaways and sandwich shops across Forest Hill and its immediate surroundings (about a mile and a half). Grease builds up on fan blades and housings in kitchens like these, unbalancing the impeller. Forest Hill is covered by Oxfordshire 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. In Forest Hill, food businesses are inspected by environmental health officers from South Oxfordshire council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
If you run catering at a healthcare site, such as a hospital like Nuffield Orthopaedic Centre about 2.5 miles west, the extract may need cleaning more often than a part-time kitchen. Volunteers running a hall kitchen near Church of St Nicholas, or anywhere in Forest Hill, may not know when the extract was last cleaned, and a grease test settles it. If you look after a school kitchen, at a school such as Sandhills Community Primary School or anywhere near Forest Hill, the holidays are the usual time for a TR19® clean.

Aftercare tips
Good habits slow the build-up between visits. A few tips:
- Keep each photo report with the maintenance log
- Keep the grease filters clean and in place
- Book the fan into every full TR19 clean
- Flag smoke lingering at the canopy
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.
Keep the route to the fan clear. 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.
What affects the cost of extract fan cleaning
Sites vary more than people expect. The main factors:
- One-off work versus a regular cycle
- The condition we find in the survey
- How many systems or sites are involved
- The scale of the work
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. You’ll have a fixed price before we start.

What we do, step by step
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. On site, the work takes a couple of hours per fan, depending on its size and the build-up. Photos of the system and how to reach it help us plan a visit to Forest Hill.
- We find the fan and check how it’s reached and how it’s isolated.
- Power to the fan is isolated before anyone touches it.
- We remove the grease from the blades, impeller and casing.
- The fan and its surrounds are degreased, keeping clear of the motor’s electrics.
- The fan is put back into service, checked and photographed.
Before we arrive
- Dig out any earlier paperwork for the system
- Allow time for equipment near the work to be turned off and cool down
- Let us know about permits to work or site inductions
