FAQs for Knave's Ash
Which council inspects kitchens in Knave's Ash?
Kitchens in Knave's Ash are inspected by Canterbury City council’s environmental health officers. A note of when the fan failed and when it was fixed shows the problem was dealt with.
Can you come to Knave's Ash after we close?
Yes, evening, overnight and weekend work is normal for us. It means the site in Knave's Ash keeps running as normal. When you call 0345 646 2711 or drop us a line, mention when the site is quiet.
Can we book visits on a schedule?
Yes. We run scheduled maintenance contracts, set at the interval the system needs. The report from each visit recommends the next date.
Can you come out in an emergency?
Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line and we’ll talk you through the next steps.
Do I get a report after the visit?
Yes. It’s the record insurers and inspectors ask to see: a dated report with pictures, listing the work and any areas we couldn’t reach.
Can one contract cover all our sites?
Yes. Our area covers London and the South East, so sites at different addresses can be planned together as one programme. Every site has its own report.
Can you tell me the price of a fan repair?
Every fan job is priced once we know the fault. Repair, parts or a full replacement all cost differently so the first step is a diagnosis.
What paperwork should we keep on file?
Every certificate and report from each visit, filed in the maintenance log, along with your own cleaning log. BESA advises that certificates record the date, location and technician.
About our extract fan repair in Knave's Ash
Diagnosis comes before parts. The motor, drive, impeller, bearings and mounts are all checked and the speed control too. Then you are given a fixed quote for the repair or the replacement. The work covers bearings, fan housings and kitchen extract fans, and people most often call us about a dead fan motor and a knocking noise from the extract fan.
In a small place like Knave's Ash, fans are often on an outside wall or roof, open to wind and rain. That, with the grease, is hard on motors and bearings.
A written report with photos follows every visit, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Looking after it afterwards
To keep the system working properly between visits:
- Report new noises from the fan early
- Keep the emergency number where staff can see it
- Make sure the isolator and controls are easy to reach
- Never run the extract with filters missing
Grease on the fan usually means grease in the duct as well. 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.
Why act early in Knave's Ash
A struggling motor runs hotter and works harder. Every hour of strain takes its toll and a burnt-out motor is a bigger job than a worn belt. Catching it early keeps the repair small. It’s simpler to plan the work at Knave's Ash now than to arrange it in a hurry later.
Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you’re unsure, give us a ring on 0345 646 2711, or email photos for straight advice and a fixed quote.

How we price extract fan repair
Your quote is based on your site. We consider:
- One-off work versus a regular cycle
- Travel, parking and unloading
- The size of the system
- The condition we find in the survey
What you pay depends on how big the system is, what state it’s in and access to every part of it. We give you a fixed price before any work starts, so you know where you stand.
What we need to know
You do not need the technical terms. It helps if you can send:
- The roof, plant room or outside wall the system runs to
- A few general shots of the system
- Any previous report or certificate
- Problems your staff have spotted
We do not publish a price list, because every site is different. We look at your system first, from pictures or on a visit, and then send you a fixed quote. To get going, give us a ring on 0345 646 2711 or send us an email.
Signs you need extract fan repair in Knave's Ash
In Knave's Ash, as anywhere, long cooking days mean long hours for the fan. Belts on a belt-driven fan stretch and wear, so the fan squeals or turns more slowly.
Common reasons sites call us are:
- An old fan that needs replacing
- An extract fan that rattles or knocks
- Weak extraction and a smoky kitchen
- A motor that trips out or overheats
Holidays are the time to replace a tired kitchen fan at schools such as Hoath Primary School, rather than mid-term.
What to look for in a quote
- Whether the figure could change on the day
- Whether the work can be done while the site is closed
- What happens if part of the system cannot be accessed
- Exactly which parts of the system are covered
Different parts, different methods
Motors and bearings
Rumbling and grinding normally come from the bearings. We diagnose whether it’s the bearings or the motor itself before recommending a fix.
Roof and wall-mounted fans
An external fan’s rattle can be heard outside. Loose fixings and worn mounts are often the cause.
What staff can safely do
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That’s our job.
How it works
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool before work begins, and floors and nearby surfaces are sheeted. On site, it takes anything from an hour or two to a full visit, depending on the fault. For a village or hamlet like Knave's Ash, tell us about narrow lanes, gates and parking when you book.
- You describe the fault and we arrange a visit.
- On site, the fan is safely isolated.
- The fan and its controls are checked to pin down the fault.
- A fixed quote for the repair or replacement follows.
- We fix the fault and run the fan to check it.
Getting ready for the visit
- Have your last certificate or report to hand
- Tell us where we can park and unload
- Let us know when the site is closed or quiet
