Common questions in Bentley Heath
Can you work in Bentley Heath outside opening hours?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. Just call us on 0345 646 2711 or email us with your opening times and we’ll plan around them.
What do you need to know about parking in Bentley Heath?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Where restrictions apply in the day, an evening or overnight visit normally gets round them.
Do you have a 24/7 line?
Yes. There’s a 24/7 emergency line, for problems that can’t wait. Ring any time and tell us what’s happened.
Who is the responsible person?
The Fire Safety Order 2005 calls them the responsible person: normally the employer or whoever controls the premises. Landlords, facilities managers and managing agents can also hold responsibility.
Do you survey before quoting?
Yes. Every job is surveyed first, from your pictures and details, or with a visit where necessary. Then you get a fixed quote.
Do you offer extract fan cleaning separately?
Yes, we can clean just the fan. It’s useful when a fan is noisy or greasy between full cleans, but it doesn’t replace a full TR19 clean.
Can we book visits on a schedule?
Yes. We run scheduled maintenance contracts, set at the interval the system needs. Each report recommends when the next visit should be.
What is TR19?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
How we handle extract fan cleaning in Bentley Heath
Think of the fan as the system’s heart and the grease as a clot. 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. Common call-outs are for a fan that hums, whines or rumbles and a fan shaking on its mounts, on axial fans, discharge points and centrifugal fans.
In a London area like Bentley Heath, a kitchen extract often passes through shared space on its way out: a riser, a service void, the floors above. A duct fire there can reach parts of the building far from the range, which is why keeping it clean to TR19® matters.
A written report with pictures follows every visit, 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.

When something else is needed
In fairness, there are a few things this work won’t fix:
- An undersized fan that cannot cope
- A failed motor or worn bearings (that needs a fan repair or replacement)
- Electrical faults in the fan’s supply or controls (an electrician’s job)
If you’re not sure, just phone us on 0345 646 2711 or drop us a line and we’ll give you a straight answer.

Part by part
Fan housings and motors
Some fans use a belt drive. Belts and pulleys are checked and cleaned where safe for your records.
Inline duct fans
Hidden in a ceiling void, an inline fan is easily missed. The survey makes sure it’s part of the clean.
Looking after it afterwards
Aftercare is simple, and it helps at the next visit:
- Don’t store items in front of the fan’s access point
- Do not turn the fan off mid-service
- Look for grease stains near the discharge
- Listen for new noises or vibration from the fan
File the photo report with your other extract records. It shows the fan’s condition at the time of the clean, which helps if anything changes later.
A change in how the fan sounds is worth noting. Rattles, hums or shaking can be early signs of build-up or wear and early action can save a repair.
Common problems we fix in Bentley Heath
The cooler the air, the more grease drops out, and on a roof or outside wall the fan can be in some of the coolest air in the system. That makes it a natural place for grease to settle.
Any of these means the system needs a check-up:
- Grease around the motor and its mounts
- Hot, greasy smells near the fan
- A fan left out of previous cleans
- An extract fan that vibrates or rattles
If you run catering at a historic house or estate in the area (Wyllyotts Manor is about 0.9 miles north), event kitchens in older buildings often have awkward duct runs that need planning.

Grease, kitchens and Bentley Heath
Look up Bentley Heath on the FSA’s food hygiene register and you’ll find about 44 restaurants, cafés and canteens and about 26 takeaways and sandwich shops in and around Bentley Heath, up to about a mile and a half out. Each kitchen extract among them ends at a fan, and grease on the impeller strains the motor. Overnight is the normal time to clean a London kitchen extract, so trading is not affected. Bentley Heath is covered by London Fire Brigade. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
Healthcare kitchens, like those at hospitals such as Barnet General Hospital (about 2.4 miles south), often cook for long hours, which puts them in BESA’s heavier-use bands. For schools such as Pope Paul Catholic Primary School, kitchen extract cleaning is typically booked for the holidays, when the canteen is closed.
Bentley Heath is about 1 mile south-west of Potters Bar, in Greater London. Anywhere in EN5, we cover extract fan cleaning for commercial sites. Our Greater London coverage runs to 764 places, Bentley Heath among them. There’s also a page for London, about 13 miles away.

What we do, step by step
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. On site, the work takes an hour or two for one fan, longer when it’s hard to reach. We fit London jobs around the building rather than the other way round, so a visit in Bentley Heath is usually out of hours.
- First we check the fan’s condition and how it sounds.
- Once isolated, we open the fan up.
- The impeller is cleaned blade by blade so it runs balanced.
- Housing, outlet and the area around the motor are cleaned.
- The fan goes back into service with a report on its condition.
Preparing for the visit
- Have your last certificate or report to hand
- Move anything stored near the system
- Make sure equipment near the work can be switched off and left to cool
How to get a quote
Quotes are quick. Send a few details and photos, and we normally reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
Related advice
Staff cleaning versus specialist work
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We will take a look and send you a fixed quote.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.

What affects the quote in Bentley Heath
The survey tells us what the work involves. The main factors are:
- Site rules, permits and inductions
- Whether it’s a one-off visit or part of a schedule
- Working hours and out-of-hours timing
- Whether several sites go on one quote
What you pay reflects the actual work. That’s why we survey first, from pictures or on site, and the price is agreed before any work starts.
Asking for a quote
There’s no need for technical detail. It helps if you can send:
- A few general shots of the system
- Your last certificate, test record or report
- Where the site is and what kind of site it is
- The roof, plant room or outside wall the system runs to
For a fixed quote, ring 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. You’ll normally have a quote within one working day.
