What extract fan cleaning looks like in Coldharbour
In Coldharbour, food businesses are inspected by environmental health officers from Mole Valley council. Extraction counts as kitchen equipment, so its condition can come up on the day. Before-and-after photos from each clean are a simple way to show the extract is in hand. The fire and rescue service for Coldharbour is Surrey 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.
If you run a church or community hall kitchen, near Christ Church or elsewhere in Coldharbour, its extract still collects grease from every lunch and event.

Extract fan cleaning in Coldharbour
Cleaning removes grease, not wear. If we find worn bearings, a struggling motor or damage to the impeller, we will tell you and fan repair or replacement is something we also do. You will know whether the fan just needed cleaning or something more. The work covers roof-mounted fans, axial fans and fan housings, and common reasons people get in touch are an extract fan that vibrates or rattles and a fan that no longer moves enough air.
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.

What staff can safely do
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, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
Coldharbour: your questions answered
Which fire authority looks after Coldharbour?
Fire safety enforcement in Coldharbour is handled by Surrey Fire and Rescue Service. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
Do you work in villages like Coldharbour?
Yes. Villages and rural sites across the South East are part of our work, Coldharbour included. A survey first, from pictures or a visit, means we arrive with the right kit.
Can you set up regular visits?
Yes. Scheduled maintenance plans are part of what we do, with visits at the interval your system needs. The report from each visit recommends the next date.
Do you need to turn the fan off to clean it?
The fan is isolated before we open it, so it cannot run during the clean. That means the extract is off, so we clean while the kitchen is closed.
Why has my extract fan got louder?
Build-up on the impeller is a frequent reason, since uneven grease makes it run out of balance. It can also be wear in the bearings or motor, which our report will flag.
Is TR19 a legal requirement?
No. TR19® is BESA’s specification, not legislation. The legal duty comes from the Regulatory Reform (Fire Safety) Order 2005: the responsible person must assess and reduce fire risk, and cleaning to TR19® is the recognised way to show grease is under control.
What is TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping and expects a risk-based approach.
Can one contract cover all our sites?
Yes. We work across South East England and London, so sites at different addresses can be planned together as one programme. Every site has its own report.
Aftercare tips
Aftercare is simple, and it helps at the next visit:
- Check the report shows the fan was cleaned
- Listen for new noises or vibration from the fan
- Keep the grease filters clean and in place
- Report grease escaping from the fan
When the fan is cleaned as part of a full TR19® Grease clean, a TR19 certificate is issued through the BESCA Vent Hygiene Elite portal. If only the fan is cleaned, the photo report says so.
Don’t run the kitchen with the extract off. Air that keeps moving carries vapour out rather than letting it settle, so keeping it running helps keep it clean.
What happens if it’s left?
A fan clean in Coldharbour doesn’t take long: it takes an hour or two for one fan, longer when it’s hard to reach. Leaving it means more wear, more noise and a bigger clean later. Rural sites cannot always move to another kitchen or room when something fails.
We do not list prices on the website, because the cost depends on the site in front of us. For a fixed quote, give us a ring on 0345 646 2711 or send us an email, and we will talk you through it.

Take a look at how cleaning jobs are priced and our accreditations and certificates.
What the work involves, part by part
Inline duct fans
Hidden in a ceiling void, an inline fan is easily missed. We find it during the survey and include it in the clean.
Impellers and blades
The blades of the impeller do the work, and grease builds up on them unevenly. An uneven coating throws it off balance, so it’s cleaned carefully blade by blade.
Managing agents and facilities teams in Coldharbour
For anyone managing more than one site, we can schedule visits across all of them on one quote. Each site gets its own report and pictures, so records stay tidy.
Keeping records across a portfolio is half the battle. Each visit produces a dated report with pictures, ready to show insurers, fire officers or EHOs.
What we do, step by step
Protection comes first: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. It takes a few hours where there are several fans or heavy deposits, and we clear up before we go. The timing of a visit to Coldharbour is set by you, and the travel is our side of the planning.
- We find the fan and check how it’s reached and how it’s isolated.
- With the fan isolated, the housing is opened.
- Grease is scraped from the impeller blades and the inside of the housing.
- Blades, housing and the area around the motor are degreased with care.
- It’s closed up, run and checked, and pictures go into your report.
Before we arrive
- Tell us about site rules, permits or sign-in
- Let us know how we reach the system, including roofs, risers and plant rooms
- Clear loose items from the work area
Getting a quote
Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before work begins.

Common problems we fix in Coldharbour
Grease builds up unevenly on the blades. The difference throws the impeller off balance, wearing bearings and mounts. What starts as a grease problem can become a mechanical one.
Common reasons sites call us are:
- Weak extraction at the canopy
- A heavily greased fan housing
- Burning smells from the fan area
- A fan left out of previous cleans
