Questions from Cotman's Ash
Can you work in Cotman's Ash outside opening hours?
Yes, nights and weekends are routine for us. The work in Cotman's Ash can fit around your hours. Just call 0345 646 2711 or drop us a line with your opening times and we will plan around them.
What if my kitchen extract fan stops in Cotman's Ash at night?
Extract fan emergencies in Cotman's Ash are covered around the clock. Phone 0345 646 2711 and we will talk through the fault and access. Tell us where the fan is and how to reach it.
Will you fit a new fan if ours can’t be repaired?
Yes, when repair doesn’t make sense. We check the duct size and the extract the kitchen needs so we confirm that first.
How much time does a fan repair need?
Most fan jobs take a few hours on site, depending on the fault and the access to the fan including running the fan afterwards. We will fit it around the kitchen’s hours where possible.
What accreditations do you have?
We hold CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
What happens if you cannot reach some of it?
Anything we cannot reach goes on the report, with a note of where it is, and we explain what access is needed, for example new access panels.
Do you look at the system first?
Yes. For many sites, pictures and a few details are enough, while bigger or harder-to-see systems are surveyed on site.
What types of premises do you cover?
All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. Work is timed around how each site runs.
About our extract fan repair in Cotman's Ash
Wherever your kitchen is in Cotman's Ash, fan work means the extract has to be isolated, so we plan it around your service. Evenings, overnight and weekends are all possible and there’s a 24/7 emergency line if the fan fails while you are cooking. If you’re dealing with a belt-driven fan that squeals and an extract fan that has stopped working, we can put it right, from belts and pulleys, kitchen extract fans and roof and wall fans onwards.
For a fan repair in or near Cotman's Ash, the more you tell us about the fan, the better the first visit: pictures of the fan, its rating plate and how to reach it all help.
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.

For landlords and multi-site operators
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we’re happy to quote for all of it.
If you look after several sites, we can schedule visits across all of them on one quote. Each site gets its own report and pictures, so records stay tidy.

When it’s something else
We will not sell you work that doesn’t address the problem, so these are the things it will not cover:
- Faults on the gas side of an interlock system, which need a Gas Safe registered engineer
- Smells from the discharge that need odour control equipment
- Faults in the building’s electrical supply, which need an electrician
If in doubt, call 0345 646 2711, or email photos and we will say what we think.

When a fan fails in Cotman's Ash
It’s Sevenoaks council that sends environmental health officers to food businesses in Cotman's Ash. Under food hygiene rules, a kitchen needs suitable and sufficient ventilation. A kitchen without a working fan has a problem to fix quickly. We cover Cotman's Ash, about 19 miles from central London, as part of our work across London and the South East. A survey and a fixed quote come first, then the visit at a time that suits you.
School kitchens cannot easily serve lunch without extraction, so if you look after one at a school like Kemsing Primary School, fix a failing fan before term starts.

Common problems we fix in Cotman's Ash
Some grease always slips past the filters and reaches the fan. It builds up on the impeller blades unevenly, so the fan runs out of balance and the noise follows.
Most sites get in touch after spotting one of these:
- A whining or grinding extract motor
- An extract that vibrates through the ductwork
- A fan rattling in its housing
- A fan that keeps cutting out
If you run a church or community hall kitchen, near Church of Saint Mary the Virgin or elsewhere in Cotman's Ash, an extract fan that rarely runs can seize or fail when it’s needed.

Different parts, different methods
Motors and bearings
The motor and its bearings work hardest. Heat, grease and long running hours all wear them.
Fan controls
Speed controllers and isolators sit between the supply and the fan. When they fail, the fan may not start or may run at the wrong speed.
Keeping the system healthy
Think of this as the after-treatment advice, short and simple:
- Don’t turn the fan down to hide a noise
- Keep all filters fitted while cooking
- Save our number for the 24/7 emergency line
- Write down when the fan misbehaves
If the fan had grease on it, the rest of the system almost certainly does too. We can book a TR19® clean of the whole extract, with a certificate and photo report.
A fan that is starting to make noise is giving you a warning. Getting it checked now means a planned repair rather than an emergency during service.
How it works
We start by comparing what we find with the survey or your photos. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes an hour or two to diagnose, then longer if parts or a new fan are needed. We agree a date with you, plan the drive to Cotman's Ash and turn up when the site is quiet.
- 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.
- We check the motor, bearings, drive, impeller and mountings.
- You hear what’s wrong and what it will cost, with a fixed quote, before we go ahead.
- The repair or replacement is carried out and the fan is run and checked.
Preparing for the visit
- Tell us about site rules, permits or sign-in
- Make sure someone can let us in and lock up afterwards
- Clear loose items from the work area

Staff cleaning versus specialist work
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
