Extract fan repair in Merton, done properly
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. Common call-outs are for poor airflow at the canopy and a motor that trips out or overheats, across fan housings, belts and pulleys and fan motors.
Rural kitchens often have fans mounted on outside walls or roofs, exposed to the weather. That, with the grease, is hard on motors and bearings.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

What extract fan repair can’t fix
It’s worth knowing the limits before booking:
- A greasy canopy and duct that a fan repair won’t touch
- Problems with the electrical supply to the fan (an electrician’s job)
- Smells from the discharge that need odour control equipment
Not sure which it is? You can call 0345 646 2711, or send details by email and we’ll tell you honestly before you book.

How it works
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. The visit takes anything from an hour or two to a full visit, depending on the fault. For a village or hamlet like Merton, tell us about narrow lanes, gates and parking when you book.
- 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.
- We check the motor, bearings, drive, impeller and mountings.
- We explain the fault and give you a fixed price for the fix.
- The repair or replacement is carried out and the fan is run and checked.
Preparing for the visit
- Tell us where we can park and unload
- Tell us about site rules, permits or sign-in
- Mention any locked doors, roof access or ceiling voids

What else we do in Merton
When a fan fails in Merton
Merton is about 52 miles from central London, well within the area we cover across London and the South East. Evening, overnight and weekend visits are all possible. Food hygiene inspections in Merton are the job of Cherwell council’s environmental health team. Food premises are expected to have suitable and sufficient ventilation under food hygiene rules. That is one more reason not to keep cooking with a broken fan.
If you run a church or community hall kitchen, near Church of St Swithin or elsewhere in Merton, an extract fan that rarely runs can seize or fail when it’s needed.

Signs you need extract fan repair in Merton

- A worn or slipping fan belt
- A failed fan that needs a replacement
- An extract fan that rattles or knocks
Around Merton, a failed fan can be reported day or night on our 24/7 line.

Questions from Merton
What if my kitchen extract fan stops in Merton at night?
Merton 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 you cover smaller places like Merton?
Yes. Villages and rural sites across the South East are part of our work, Merton included. A survey first, from pictures or a visit, means we arrive with the right kit.
Does the report say when we need you again?
Yes. How often depends on use and condition and the report sets out why.
What’s TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked, and it takes a risk-based approach.
What paperwork should we keep on file?
Everything that shows the system is looked after: reports, certificates, pictures and your own cleaning or check logs. A single log for each site works best.
What about areas you cannot get to?
They’re listed in the report, never skipped quietly. The report says which parts couldn’t be reached and why, along with a quote to put access in.
Who is responsible for fire safety on the premises?
That depends on who controls the premises. Under the Fire Safety Order 2005, it’s the responsible person, which may be the employer, owner, landlord, facilities manager or managing agent.
What types of premises do you cover?
All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. We fit the work around how the site operates.
What staff can safely do
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We can diagnose it and quote.
Why deal with it now?
Wherever the kitchen is, Merton included, the fan often sits on an outside wall or roof, so its noise does not stay in the kitchen. Fixing the cause quietens it down before it becomes a nuisance. With notice, the visit to Merton can be fitted around your bookings and events.
What you pay depends on the size of the system, what state it’s in and access to every part of it. We give you a fixed price before work begins, so there are no surprises.

Different parts, different methods
Roof and wall-mounted fans
An external fan’s rattle can be heard outside. It’s often down to loose mounts or worn bearings.
Belt-driven fans
With belts and pulleys, there’s more to wear. That means more to check, but often a simpler repair.
