Extract fan repair for kitchens and businesses in Thornton Heath
Kitchens in Thornton Heath call us about extract fans and motors that are noisy, slow or dead, we find the cause and quote a fixed price to repair or replace it. When the fan gives up mid-service, our 24/7 emergency line is there. The work covers kitchen extract fans, bearings and belts and pulleys, and the jobs we see most are a humming noise from the fan motor and an extract fan that rattles or knocks.
London extract fans often sit on rooftops, exposed to the weather as well as the grease, and bearings, belts and motors wear out in the end. A fan that is noisy or vibrating is giving a warning.
Good records are part of the job. You get a written report with photos after every visit, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

What affects the cost of extract fan repair
Before we fix a price, we need to know a few things. We check:
- How big the system is
- How many systems or sites are involved
- Travel, parking and unloading
- Whether we need access equipment or extra panels
When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote and give you a fixed price before we start.
What we need to know
What to send for a quote:
- Problems your staff have spotted
- Photos showing the whole system and its surroundings
- The roof, plant room or outside wall the system runs to
- The times we could work without disrupting the site
Every quote begins with a look at the system, from your pictures and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work, before work begins.
Staff cleaning versus specialist work
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
Staff cleaning and specialist work aren’t 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.
Looking after it afterwards
Looking after the system between visits is straightforward, and it helps at the next visit:
- Save our number for the 24/7 emergency line
- Keep the area around the fan controls clear
- Tell us about a new rattle or whine right away
- Get a noisy fan checked rather than slowed down
Before we leave, the fan is run and checked. You will hear what we found and what we did, and anything else we noticed is pointed out.
A 3, 6 or 12-monthly cleaning plan brings us back at set intervals, so the fan is looked at as part of each visit and problems are spotted sooner.
Leave it or put it right?
Wherever the kitchen is, Thornton Heath included, the fan often sits on an outside wall or roof, where a rattle or a whine can be heard beyond the kitchen. Fixing the cause quietens it down before neighbours notice. Planning ahead in Thornton Heath lets you pick a quiet night rather than lose a busy one.
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, which can make the next visit longer. If you are unsure, ring 0345 646 2711 or email us for straight advice and a fixed quote.

Landlords, agents and facilities managers
Records are where multi-site compliance often slips. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side, and the report can go to both.
How it works
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. The visit itself takes a few hours for most repairs, longer for a full fan replacement. In Thornton Heath, as across London, we normally work overnight or at weekends and hand the site back ready to open.
- A visit is booked, in the evening or overnight if that suits.
- We isolate the extract and open the fan housing.
- Bearings, drive, impeller, motor and mounts are inspected.
- We explain the options and quote a fixed price.
- We complete the work and check the fan runs smoothly.
Before we arrive
- Allow time for equipment near the work to be turned off and cool down
- Find the previous report, if there is one
- Let us know when the site is closed or quiet
Get a fixed quote
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.

Your questions about extract fan repair in Thornton Heath
Can you come out to a failed extract fan in Thornton Heath out of hours?
Day or night, a failed fan in Thornton Heath can be reported on our emergency line. The number to ring is 0345 646 2711. If you can, stop cooking until the fan is checked.
Can the work in Thornton Heath be done at night or at weekends?
Yes. We work evenings, overnight and at weekends. It means the site in Thornton Heath keeps running as normal. Just call 0345 646 2711 or drop us a line with your opening times and we’ll plan around them.
Does a faulty extract fan always need replacing?
Repair is always our starting point. Where the motor has burnt out or the fan is worn out, replacing it can be the better answer, and we will explain why.
How much notice do you need?
For planned work, earlier is better, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.
Is TR19 cleaning required by law?
Not in itself. Insurers, fire officers and EHOs look to TR19® as the benchmark, and many insurance policies ask for proof of TR19® cleaning. The legal duty sits in the Regulatory Reform (Fire Safety) Order 2005, which applies in England and Wales.
How long will the fan be out of action?
Most fan jobs take a few hours for most repairs, longer for a full fan replacement, including testing. We plan the work around your service where possible.
Which kinds of sites do you work on?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.
Does the report say when we need you again?
Yes. The interval depends on how much the system is used and what we find, and we explain the reasoning on the report.

Every one of them that cooks under a canopy depends on its extract fan to keep cooking. London extract fans are often at the end of long duct runs, on roofs or in basements. Kitchens in Thornton Heath get their food hygiene inspections from Croydon council. Food premises are expected to have suitable and sufficient ventilation under food hygiene rules. Getting the fan running again is the priority.

When to call us in Thornton Heath
Some faults are in the controls rather than the fan. A failed speed controller or a wiring fault can stop a fan, and a fan that will not start is not always a dead motor.
Clients usually contact us after spotting one of these:
- A fan worn beyond sensible repair
- An extract fan that rattles or knocks
- A worn or slipping fan belt
- Weak extraction and a smoky kitchen
Occasional-use kitchens, such as a hall kitchen near Church of St Stephen or elsewhere in Thornton Heath, are where a stiff or seized fan can turn up.
