In-house cleaning or a specialist?
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
How we handle extract fan repair in Crystal Palace
The extract fan is what pulls smoke, heat and steam out of the kitchen. When it starts to rattle, hum or slow down, the cooking area soon fills with heat and fumes. We find out why and put it right, by repairing the fan or replacing it. Typical jobs include a worn or slipping fan belt and a knocking noise from the extract fan, on belts and pulleys, fan motors and bearings.
Rooftop fans in London take the weather as well as the grease from below, and in time, bearings, belts and motors fail. A fan that’s noisy or vibrating is giving a warning.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Questions from Crystal Palace
Who do I call if an extract fan fails in Crystal Palace?
Day or night, a failed fan in Crystal Palace can be reported on our emergency line. Use 0345 646 2711, our emergency number, at any time. Tell us where the fan is and how to reach it.
Who would carry out a food hygiene inspection at a kitchen in Crystal Palace?
Kitchens in Crystal Palace are inspected by Croydon council’s environmental health officers. If the extract fan has failed, it’s worth having the repair booked, and the details to hand, before an officer visits.
Do you look at the system first?
Yes. Every job is surveyed first, from your pictures and details, or with a visit where necessary. Then you get a fixed quote.
Can one contract cover all our sites?
Yes. We work across South East England and London, so we can schedule a run of sites as one programme. Every site has its own report.
Can you repair a fan rather than replace it?
Often, yes. Many faults are fixed by cleaning the impeller or renewing worn parts and we only recommend replacement when repair does not make sense.
Does the report say when we need you again?
Yes. Every report includes a recommended date for the next visit, based on what we found and how the system is used.
Does the law say we must follow TR19?
No, not in itself. TR19® is the benchmark insurers, fire officers and EHOs check against, and many insurance policies ask for proof of TR19® cleaning. The legal duty sits in the Regulatory Reform (Fire Safety) Order 2005 in England and Wales.
Do you replace extract fans as well as repair them?
We do. Where a fan is beyond repair, we replace it with one suited to the duct and the kitchen, and you get a fixed quote first.
Landlords, agents and facilities managers
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 can quote for the whole system.
Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.
Part by part
Impellers and housings
A damaged or corroded impeller can’t simply be cleaned. It may be replaced on its own, or with the whole fan.
Roof and wall-mounted fans
Fans outside are exposed to rain and condensation. Rust on fixings and housings is a frequent find.
What we do, step by step
Our technicians bring everything the work needs, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. The visit takes a few hours on site, depending on the fault and the access to the fan. If your building in Crystal Palace has sign-in rules, permits or key holders, mention them when you book.
- First, you tell us the symptoms: noise, shaking, weak extraction or no power.
- With the fan safely isolated, we open it up for a proper look.
- Each part is checked in turn: motor, bearings, drive, impeller and fixings.
- You hear what’s wrong and what it will cost, with a fixed quote, before we go ahead.
- Once the work is done, we run the fan and check it’s steady and quiet.
Before we arrive
- Make sure someone can let us in and lock up afterwards
- Clear the space around the work
- Tell us about site rules, permits or sign-in
How to get a quote
The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.

What else we do in Crystal Palace
What a clean won’t put right
We’d rather tell you now than book work that won’t help, so here are the limits:
- Smells from the discharge that need odour control equipment
- Ductwork designed too small for the kitchen’s cooking
- Problems with the gas supply or its interlock valve
Not sure which it is? You can call us on 0345 646 2711, or email photos and we’ll tell you honestly.

Why it’s worth doing now in Crystal Palace
Weak extraction leaves heat, smoke and fumes in the kitchen. The kitchen becomes an uncomfortable place to work, and more grease settles where it shouldn’t. Leaving it on a busy London site only adds to the work.
What you pay reflects the actual work. That’s why every job is surveyed first, and the price is agreed before work begins.

Between visits
Aftercare is simple, and it makes the next visit easier:
- Book regular TR19 cleaning, which includes the fan
- Clean or change filters on schedule
- Make sure the isolator and controls are easy to reach
- Keep all filters fitted while cooking
Before we leave, the fan is run and checked. We explain the fault and the fix, and anything else we noticed is pointed out.
When filters block, the fan works harder. Keeping filters clean eases the strain and helps prevent overheating.
Extract fans in Crystal Palace
Look up Crystal Palace on the FSA’s food hygiene register and you will find about 237 restaurants, cafés and canteens and about 138 sandwich bars and takeaways within 1.5 miles or so of the middle of Crystal Palace. Every one of them that cooks under a canopy depends on its extract fan to keep cooking. We ask about access first for a London fan job, because roofs and basements need planning. In Crystal Palace, food businesses are inspected by environmental health officers from Croydon council. Food premises are expected to have suitable and sufficient ventilation under food hygiene rules. A kitchen without a working fan has a problem to fix quickly.
Holidays are the time to replace a tired kitchen fan at schools such as Crystal Palace School, rather than mid-term. If you run a church or community hall kitchen, near St Paul's or elsewhere in Crystal Palace, an extract fan that rarely runs can seize or fail when it’s needed. If you run a café or takeaway near Crystal Palace station, a failed fan in the middle of service is exactly what our 24/7 emergency line is for.
