Extractor fan repair in Merton Park
Our technicians work in Merton Park on repair and replacement of kitchen extract fans, fan motors and worn fan parts. Fixed quotes, work around your opening hours and photo reports as standard.
- An extract fan that has stopped working
- A fan that keeps cutting out
- Poor airflow at the canopy
What happens on the day
The first job on site is protection: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. It takes part of a day for most faults, with a return visit if parts have to be ordered, and the area is cleaned down before we leave. Many London buildings have a managing agent, a security desk or a permit-to-work system, so tell us who to contact in Merton Park.
- We agree a time to attend, out of hours if needed.
- The extract is switched off and the fan opened up.
- Bearings, drive, impeller, motor and mounts are inspected.
- You hear whether repair or replacement makes sense, with a fixed quote.
- We complete the work and check the fan runs smoothly.
Before we arrive
- Clear loose items from the work area
- Mention any locked doors, roof access or ceiling voids
- Plan for cooking equipment or plant to be off before we arrive
Get a fixed quote
We do not publish a price list, because no two systems are the same. We look at your system first, from photos or on a visit, then send a fixed quote. To start, phone us on 0345 646 2711 or drop us a line.

Extract fan repair in Merton Park
Before anything is ordered, we diagnose. The motor, drive, impeller, bearings and mounts are all checked and the speed control too. Then you are given a fixed quote for the repair or the replacement. The work covers fan housings, roof and wall fans and fan motors, and common reasons people get in touch are an extract fan that has stopped working and an old fan that needs replacing.
Replacing a fan in a London building often means working at height or in a tight plant space, with parking and lifting to arrange in Merton Park. Work can be done after service, so the kitchen loses as little time as possible.
For insurers and inspectors, the record counts. So every job comes with a written report and pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Why deal with it now?
A noisy fan rarely fixes itself. Bearings that are left to wear can fail suddenly, and that often happens mid-service. A repair booked now is simpler than an emergency later. A busy site in Merton Park builds up dirt and wear quickly, so putting it off makes the eventual job larger.
Combining work into one visit or one programme can make for a more efficient booking. Mention every system or site you need covered, and you’ll get one fixed quote.
Why book with us

Take a look at what affects the cost and our accreditations.
When a fan fails in Merton Park
The FSA’s food hygiene register shows about 306 restaurants, cafés and works canteens and about 56 takeaways within 1.5 miles or so of the middle of Merton Park. Wherever they cook under a canopy, a failed extract fan stops the kitchen. Lifting a replacement fan onto a London roof can need a loading slot and the building’s agreement. Environmental health officers from Merton council inspect food businesses in Merton Park. Food hygiene rules expect food premises to have suitable and sufficient ventilation. So a failed fan is worth fixing before the next service, not the next month.
If you run a church or community hall kitchen, near St Mary's Church or elsewhere in Merton Park, an extract fan that rarely runs can seize or fail when it’s needed. For a takeaway near South Merton station, a fan that fails on a busy evening means turning customers away, and our emergency line runs 24/7.
Merton Park is about 1 mile south-east of Wimbledon, in Greater London. Sites in Merton Park get the same service as everywhere we cover: a survey first, a fixed quote, work timed around your hours and a report with pictures.

Signs you need extract fan repair in Merton Park
When filters clog and ducts fill with grease, the fan has to strain. A motor that strains runs hot and may cut out or fail.
Signs it’s time to call us include:
- An extract fan that rattles or knocks
- A belt-driven fan that squeals
- A fan that keeps cutting out
- A fan that won’t start at all
Holidays are the time to replace a tired kitchen fan at schools such as Merton Park Primary School, rather than mid-term.
What your quote should include
- Whether the quote is based on a survey or photos
- When the next visit should be, and why
- Whether the figure could change on the day
- Whether the work can be done while the site is closed
For landlords and multi-site operators
If you look after several sites, we can plan visits across the whole estate and price them together. Every building has its own written report, so records stay tidy.
Whether it’s one building or many, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with photos.
Between visits
Think of this as the after-treatment advice, in brief:
- Never run the extract with filters missing
- Report new noises from the fan early
- Make sure the fan is cleaned with the rest of the system
- Make sure staff know who to call if the fan fails
We run the fan and check it’s steady before we go. You will hear what we found and what we did along with anything else that needs watching.
Clogged filters make the fan strain. Keeping filters clean eases the strain and protects the motor.
Merton Park questions
Who inspects food businesses in Merton Park?
That’s Merton council, whose environmental health officers carry out food hygiene inspections in Merton Park. An officer may ask how the kitchen is ventilated, so keep repair records with your maintenance file.
Can you come out to a failed extract fan in Merton Park out of hours?
Day or night, a failed fan in Merton Park can be reported on our emergency line. Use 0345 646 2711, our emergency number, at any time. Details of the make and model help us plan the repair.
What accreditations do you have?
Our accreditations are CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
How far ahead should we book?
It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and for anything urgent, ring our 24/7 emergency line.
Do you have insurance?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
Is TR19 a legal requirement?
No. TR19® is BESA’s specification, not legislation. The legal duty comes from the Regulatory Reform (Fire Safety) Order 2005: the responsible person must assess and reduce fire risk, and TR19® is the benchmark for showing that grease in the extract is under control.
How long does an extract fan repair take?
Typically, a fan repair takes a few hours on site, depending on the fault and the access to the fan. Where parts need ordering, we will explain the timescale.
What types of premises do you cover?
Any commercial site with kitchens or ventilation, from a single café to a large school. We work with hotels, schools, care homes, offices, retail and leisure sites.
Staff cleaning versus specialist work
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.
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.
What affects the cost of extract fan repair
The survey tells us what the work involves. The main factors are:
- The size of the system
- Working hours and out-of-hours timing
- Site rules, permits and inductions
- How many systems or sites are involved
What you pay depends on the size of the system, the condition it’s in and access to every part of it. We give you a fixed price before we start, so you know where you stand.
What we need to know
Before you ask for a quote, gather:
- Any symptoms, from odd noises to smells or leaks
- Detail shots of panels, filters and grilles
- Any previous report or certificate
- Wide pictures of the system and the area around it
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.
