Questions from Middle Park
Is there an emergency callout for extract fans in Middle Park?
We run a 24/7 emergency line for failed extract fans, and Middle Park is part of our area. Use 0345 646 2711, our emergency number, at any time. A photo of the fan’s rating plate helps.
Can parking be tricky for a job in Middle Park?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. If the building has a loading slot system, we’ll book into it.
How much time does a fan repair need?
Most fan jobs take part of a day for most faults, with a return visit if parts have to be ordered including running the fan afterwards. We plan the work around your service wherever we can.
What happens to the waste?
It leaves the site with us when we go. While we work, it’s kept contained so the area stays clean.
Why is our extract fan so noisy?
Common causes are grease on the impeller, worn bearings, slipping belts and loose mountings. Rattles, whines and grinding point to different faults and we find the exact cause on site.
How much does an extract fan repair cost?
The price depends on the diagnosis. After we’ve checked the fan, we give you a fixed price for the repair or the replacement.
Do you work with multi-site operators?
Yes. One number covers all your sites across London and the South East, and visits can be set on a regular cycle.
Do you provide a certificate or report?
Yes. You get a written report with photos after every visit, covering the work, any areas we couldn’t access and the recommended next date. Kitchen extract cleans to TR19® Grease also get a certificate through the BESCA Vent Hygiene Elite portal.
Extract fan repair for kitchens and businesses in Middle Park
Across Middle Park, we deal with fan faults of every kind, from a squeal at start-up to a fan that won’t run at all. The fault is diagnosed, quoted at a fixed price and put right, or the fan is replaced if repair does not make sense. Common call-outs are for a whining or grinding extract motor and an extract fan that has stopped working, across roof and wall fans, belts and pulleys and bearings.
Rooftop fans in London take the weather as well as the grease from below, and bearings, belts and motors wear out in the end. Noise and vibration are worth reporting before the fan stops.
The sign-off is always in writing: a dated report with pictures of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

Different parts, different methods
Motors and bearings
Rumbling and grinding typically come from the bearings. We diagnose whether it’s the bearings or the motor itself and then recommend the fix.
Direct-drive fans
Grease on the impeller unbalances a direct-drive fan quickly. Cleaning it can cure the noise, if the bearings haven’t been damaged.
What extract fan repair looks like in Middle Park
There are about 125 cafés, restaurants and staff canteens and about 64 takeaways and sandwich shops in Middle Park and the streets around it, up to about 1.5 miles out, according to the Food Standards Agency’s register. Those that cook under a canopy rely on a fan that runs every hour they’re open. Food hygiene inspections in Middle Park are the job of Bromley council’s environmental health team. Ventilation is part of food hygiene law, which expects it to be suitable and sufficient. So a failed fan is worth fixing before the next service, not the next month. In London, a fan on a roof or in a basement can take planning to reach, with parking and loading to arrange.
If you cook near Mottingham station, long trading hours wear fan belts and bearings, so noise and vibration are worth reporting early. If you run a school kitchen, at a school such as Middle Park Primary School or nearby, a fan that’s getting noisy is best repaired in the holidays before it fails in term.

Why act early in Middle Park
In kitchens with an interlocked gas supply, no extract can mean no cooking. Without extraction, the heat and fumes build up fast, so a failing fan is worth dealing with early. London buildings are shared, so a fire or failure in one system can reach the neighbours above and beside you.
Working hours, access and the scale of the site all affect the cost. Each of those is built into the quote, and the price is fixed before work begins.

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 are happy to quote for all of it.
For anyone managing more than one site, we can schedule visits across all of them on one quote. Every building has its own written report, so records stay tidy.

What else we do in Middle Park
How the visit works
There are three stages on the day: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and photos. Most of the time goes on the work itself, and that takes an hour or two to diagnose, then longer if parts or a new fan are needed. Getting kit into a London building takes planning, so let us know where we can load and park in Middle Park.
- First, you tell us the symptoms: noise, shaking, weak extraction or no power.
- The fan is isolated and opened up so we can see inside.
- Each part is checked in turn: motor, bearings, drive, impeller and fixings.
- You get our diagnosis and a fixed quote to repair or replace.
- The repair or replacement is carried out and the fan is run and checked.
Preparing for the visit
- Dig out any earlier paperwork for the system
- Make sure someone can let us in and lock up afterwards
- Mention any locked doors, roof access or ceiling voids
How to get a quote
To get a fixed quote, ring 0345 646 2711, or send details by email with the site type, your trading hours and a short description of the system. A few photos and your last certificate or report help a lot. You’ll typically have a quote within one working day.

What staff can safely do
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We will take a look and give you a fixed quote.
When to call us in Middle Park
In Middle Park, as anywhere, long cooking days mean long hours for the fan. Belts on a belt-driven fan stretch and wear and a slipping belt means slower fan speed and weaker extraction.
What we’re most often called out for:
- A fan rattling in its housing
- An extract that vibrates through the ductwork
- A fan that keeps cutting out
- An old fan that needs replacing
If you run a church or community hall kitchen, near Church of St Saviour or elsewhere in Middle Park, an extract fan that rarely runs can seize or fail when it’s needed.
Before booking anyone
- Whether VAT is included
- What insurance they carry
- What paperwork you get at the end
- Whether the figure could change on the day
Looking after it afterwards
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Do not turn the fan down to hide a noise
- Do not wait for a noisy fan to stop
- Make sure staff know who to call if the fan fails
- Do not cook with gaps in the filter bank
We run the fan and check it’s steady before we go. You’ll hear what we found and what we did, and anything else we noticed is pointed out.
Noise is normally the first sign of a fan problem. Getting it checked now means a planned repair instead of a breakdown at the worst moment.
