Extract fan repair in Croydon, done properly
Grease is hard on extract fans. Deposits on the impeller throw it out of balance and the vibration wears out bearings and fixings. That’s why we check the grease whenever we work on a fan and can arrange a TR19® clean of the whole system at the same time. We’re often asked to deal with a knocking noise from the extract fan and a fan worn beyond sensible repair, across kitchen extract fans, roof and wall fans and fan motors.
In London, a kitchen without working extraction can’t keep cooking safely, and a closed kitchen loses a night’s trade. In Croydon, as across London, fans often sit on a roof or deep in a plant space, so access is the first thing we ask about.
Each visit ends with a written report and pictures, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Leave it or put it right?
A struggling motor runs hotter and works harder. Every hour of strain takes its toll, and when it finally fails, it may take other parts with it. Early attention keeps the cost and disruption down. Choosing the date yourself beats having a fault choose it for you.
You will not find a price list here, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll talk you through it.

Extract fan repair around Croydon
Look up Croydon on the FSA’s food hygiene register and you’ll find about 246 cafés, restaurants and staff canteens and about 160 sandwich bars and takeaways across Croydon and its immediate surroundings (about a mile and a half). Every one of them that cooks under a canopy depends on its extract fan to keep cooking. Kitchens in Croydon get their food hygiene inspections from Croydon council. A kitchen with no working extract can fall short of the suitable and sufficient ventilation food hygiene rules expect. A kitchen without a working fan has a problem to fix quickly. London extract fans are often at the end of long duct runs, on roofs or in basements.
School kitchens can’t easily serve lunch without extraction, so if you look after one at a school like Heathfield Academy, fix a failing fan before term starts. If you cook near South Croydon station, long trading hours wear fan belts and bearings, so noise and vibration are worth reporting early.

Managing agents and facilities teams in Croydon
Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and photos, so each one has its own record.
What affects the quote in Croydon
Before we fix a price, we need to know a few things. We look at:
- Parking and loading at the site
- One-off work versus a regular cycle
- The scale of the work
- The condition of the system
Every site is different, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.
Asking for a quote
When you contact us, these details help:
- The postcode and the type of business
- How we’d reach plant on a roof or in a plant room
- Wide photos of the system and the area around it
- The times we could work without disrupting the site
The quickest way to a quote is to send pictures: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.

What else we do in Croydon
Common problems we fix in Croydon
Kitchen extract fans in Croydon face the same conditions as anywhere else: hot, greasy, damp air for hours on end. Moisture can rust housings and fixings and eventually any fan simply wears out.
Any of these means the system needs a check-up:
- An extract that vibrates through the ductwork
- A fan running too slowly to clear the kitchen
- A fan that will not start at all
- A fan worn beyond sensible repair
Hall kitchens near St Andrew's, or anywhere around Croydon, often use their fans only now and then, and an idle fan can stick.
Questions to ask before booking
- If they look at the system before pricing
- Whether they’re fully insured
- Whether VAT is included

Your questions about extract fan repair in Croydon
Can the work in Croydon be done at night or at weekends?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in Croydon needn’t be disturbed. Tell us your opening hours when you ask for a quote.
What if my kitchen extract fan stops in Croydon at night?
Croydon is covered, and our emergency callout runs 24/7. Ring 0345 646 2711 at any hour and describe the fault. Details of the make and model help us plan the repair.
Do I get a report after the visit?
Yes, on every job. It’s a dated, written report with photos, and TR19® Grease cleans come with a certificate through the BESCA VHE portal. Keep it in your maintenance log.
Who is responsible for fire safety on the premises?
The law calls them the responsible person. It’s normally the employer, or whoever controls the building, and where several people have control, each can have duties. Your lease and fire risk assessment should make it clear.
Do you offer maintenance contracts?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, depending on what the system needs.
How do you protect the area?
We start with protection: floor sheeting and covers over nearby surfaces and equipment. The area is left tidy, with our waste taken away.
Can you supply and fit a replacement fan?
Yes, when repair does not make sense. The replacement has to suit the ductwork and the cooking so we confirm that first.
Do you survey before quoting?
Yes, every time. Diagnosis comes before treatment: the survey shows what needs doing and what access we need, and the quote is based on that.
How the visit 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 hand over the paperwork. On site, the work takes part of a day for most faults, with a return visit if parts have to be ordered. Security desks and permits-to-work are routine in London, so let us know what your building in Croydon needs from us.
- We take details of the symptoms and book a time that suits the kitchen.
- We isolate the fan before touching it.
- 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.
Preparing for the visit
- Tell us the best time to work, such as after service or at a weekend
- Mention any parking or loading restrictions
- Clear loose items from the work area
Get a fixed quote
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before any work starts.
Advice
What your team can do, and what needs us
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
