FAQs for Bisley
Who do I call if an extract fan fails in Bisley?
Our emergency line runs 24/7, and Bisley is within the area we cover. Use 0345 646 2711, our emergency number, at any time. Tell us where the fan is and how to reach it.
Which council inspects kitchens in Bisley?
In Bisley, it’s Surrey Heath council that carries out food hygiene inspections. A note of when the fan failed and when it was fixed shows the problem was dealt with.
Do you recommend a next date?
Yes. The recommended date is on the report. For kitchen extracts, BESA’s minimum intervals run from every 3 months for heavy use to every 12 months for light use, and fire dampers need testing at least once a year.
What paperwork should we keep on file?
Each report and certificate we give you, kept together in your maintenance log with your in-house cleaning records. BESA advises that certificates record the date, location and technician.
Do you provide a certificate or report?
Yes, always. It’s a dated, written report with photos, plus a certificate via the BESCA Vent Hygiene Elite portal for TR19® Grease cleans. File it with your fire safety records.
Are you insured?
Yes. We are fully insured, and we can share the details when you need them.
Is there a survey before the work?
Yes, every time. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
Which kinds of sites do you work on?
Any site with a kitchen or a ventilation system to look after, from a single café to a large school. We work with hotels, schools, care homes, offices, retail and leisure sites.
About our extract fan repair in Bisley
Extract fan repair starts with a diagnosis. Noise can come from grease on the impeller, worn bearings or a slipping belt, while a fan that won’t start may have a motor or control fault. You hear what we have found before any work goes ahead. We are often asked to deal with an overheating extract motor and weak extraction and a smoky kitchen, on roof and wall fans, bearings and belts and pulleys.
For a fan repair near Bisley, we plan the journey and bring what the job is likely to need, so pictures of the fan and its rating plate help.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

How it works
A visit follows the same order every time: sheeting and protection first, make the system safe, carry out the extract fan repair, tidy up and leave you the report. On site, the work takes an hour or two to diagnose, then longer if parts or a new fan are needed. Around Bisley, access is normally simpler than in a town centre, though gates and roof access are worth mentioning.
- 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.
- We explain the fault and give you a fixed price for the fix.
- Once the work is done, we run the fan and check it’s steady and quiet.
Before we arrive
- Agree a time when the area can be out of use
- Move anything stored near the system
- Let us know about parking and loading

Landlords, agents and facilities managers
Multi-site operators often want one contractor and one number. We cover South East England and London, so a run of sites can go into one programme and kept on a regular cycle.
Managing agents often deal with us directly. Send the address, what’s needed and how access works and we will come back with a fixed quote.
In-house cleaning or a specialist?
In-house cleaning and specialist cleaning do different jobs. 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.
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 the job changes from site to site
Belt-driven fans
Belt drives have more moving parts than direct-drive fans. More parts to inspect, but many faults are straightforward to fix.
Fan controls
We check the controls as part of every diagnosis since the motor is not always to blame.
Honest limits
Before you book, it helps to know what’s not included:
- A system that needs redesigning rather than repairing
- Problems with the electrical supply to the fan (an electrician’s job)
- Grease build-up in the rest of the extract system
If you are not sure, just give us a ring on 0345 646 2711, or email photos and we’ll give you a straight answer before you book.

What extract fan repair looks like in Bisley
Food Standards Agency data counts about 15 cafés, restaurants and staff canteens and about 8 takeaways and sandwich shops across Bisley and its immediate surroundings (about a mile and a half). A kitchen with a dead extract fan gets hot and smoky fast, and kitchens like these feel it at once. In Bisley, food businesses are inspected by environmental health officers from Surrey Heath council. 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. Bisley is about 26 miles from central London, well within the area we cover across London and the South East. We work evenings, overnight and at weekends, so the visit fits around the site.
If you look after a church or hall kitchen near Church of St John the Baptist, or anywhere in Bisley, test the extract fan before a big event rather than on the day.

Why act early in Bisley
Left alone, vibration spreads its damage. Fixings work loose and joints in the ductwork can be strained, so a small repair can grow into a bigger one. It’s easy to lose track of when the work was last done on a quieter site.

What we’re called out for in Bisley
In Bisley, as anywhere, long cooking days mean long hours for the fan. On belt-driven fans, belts stretch, crack and start to slip and a slipping belt means slower fan speed and weaker extraction.
Any of these means the system needs a check-up:
- A failed fan that needs a replacement
- An extract that vibrates through the ductwork
- A dead fan motor
- A whining or grinding extract motor
School kitchens cannot easily serve lunch without extraction, so if you look after one at a school like Bisley CofE Primary School, fix a failing fan before term starts.
