Extract fan cleaning in Cudham
Every TR19® Grease clean includes the extract fan, but some fans need cleaning between full cleans, for example when it’s noisy or vibrating. A fan-only clean is recorded as exactly that. Typical jobs include thick grease on the impeller and casing and vibration from an unbalanced impeller, on axial fans, roof-mounted fans and centrifugal fans.
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 pictures of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

Grease, kitchens and Cudham
There are about 8 restaurants, cafés and works canteens in and around Cudham, up to about a mile and a half out, according to the Food Standards Agency’s register. Where they cook under a canopy, an extract fan is pulling grease-laden air through its blades every service. Environmental health officers from Bromley council inspect food businesses in Cudham. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A dated certificate in the maintenance file answers the question before it’s asked. Cudham is covered by Kent Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract.
If you run catering at a historic house or estate in the area (Down House is about 1.4 miles north-west), event kitchens in older buildings often have awkward duct runs that need planning. Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Orpington Hospital is the nearest hospital to Cudham, about 3.3 miles north. If you run a church or community hall kitchen, near Church of St Peter and St Paul or elsewhere in Cudham, its extract still collects grease from every lunch and event.

Different parts, different methods
Kitchens with long cooking hours
A fan in a long-hours kitchen runs for most of the day, which means grease and wear add up quickly. Cleaning on time helps keep it running.
Roof-mounted fans
On a roof, the air is cooler and grease drops out faster. The impeller and housing are scraped and degreased.
Why act early in Cudham
Without a working extract fan, a kitchen can’t cook safely. Grease is often where fan trouble begins, so cleaning the fan helps keep it working. We also offer a 24/7 emergency callout if the worst happens. Out of sight is the usual reason a rural system goes too long without attention.
No two sites are the same, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all play a part.

Other services in Cudham
For landlords and multi-site operators
Multi-site operators often want one contractor and one number. We work across London and the South East, so a run of sites can go into one programme and kept on a regular cycle.
If you look after several sites, we can plan visits across the whole estate and price them together. Every building has its own written report, so records stay tidy.
Aftercare tips
So the system stays in good health:
- Listen for new noises or vibration from the fan
- Keep access to the fan clear
- File the fan’s report with your other records
- Book the fan into every full TR19 clean
The photo report shows the fan before and after cleaning. It notes what was done and anything that couldn’t be reached, along with the recommended next clean date.
Keep the whole system on its cleaning cycle. Regular full cleans keep the fan from building up heavy deposits, in line with BESA guidance.
What happens on the day
Protection comes first: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. The work on site takes an hour or two for most single fans, and we clear up before we go. If the van will struggle with a lane or gateway near Cudham, let us know and we’ll plan around it.
- Diagnosis first: we look for grease, noise and vibration.
- Once isolated, we open the fan up.
- The impeller is cleaned blade by blade so it runs balanced.
- We clean the casing, the outlet and around the motor.
- We run the fan and note its condition in the photo report.
How to prepare
- Let us know when the site is closed or quiet
- Make sure equipment near the work can be switched off and left to cool
- Let us know about parking and loading
