How we handle extract fan repair in Millwall
A faulty fan does not always mean a new one. Sometimes cleaning the impeller or renewing worn parts is enough and we’ll say so. Where the motor has burnt out or the unit is past saving, we fit a replacement matched to the duct and the kitchen. Typical jobs include an extract fan that has stopped working and a humming noise from the fan motor, on fan motors, roof and wall fans and bearings.
In London, getting a new fan to the roof or plant room can take planning, and in Millwall, parking and lifting are part of that. 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 photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Fixed quotes for extract fan repair in Millwall
You will get a fixed price before any work starts. It’s based on:
- Whether it’s a one-off visit or part of a schedule
- Site rules, permits and inductions
- Where the site is and how we reach it
- The scale of the work
What you pay depends on how big the system is, the condition it’s in and how easy it is to reach. You get a fixed price before we start, so you know where you stand.
Asking for a quote
To help us quote quickly, send us:
- Detail shots of panels, filters and grilles
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Your opening hours and when the area is out of use
- A few general shots of the system
Quotes are quick. Call or email with a few details and you will usually have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
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.
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.
How it works
Protection comes first: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. It takes a few hours on site, depending on the fault and the access to the fan, and the area is cleaned down before we leave. Security desks and permits-to-work are routine in London, so let us know what your building in Millwall needs from us.
- A visit is booked, in the evening or overnight if that suits.
- 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.
- The fan is repaired or replaced, then checked running.
Before we arrive
- Mention any locked doors, roof access or ceiling voids
- Clear loose items from the work area
- Mention any parking or loading restrictions
Getting a quote
Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
Related advice
When to call us in Millwall
Any kitchen that cooks for long hours works its fan hard, in Millwall or anywhere else. On belt-driven fans, belts stretch, crack and start to slip and a slipping belt means slower fan speed and weaker extraction.
What we are most often called out for:
- A fan rattling in its housing
- Vibration spreading from the fan into the ducts
- A fan that will not start at all
- A fan running too slowly to clear the kitchen
If you look after a church or hall kitchen near Church of St Nicholas, or anywhere in Millwall, test the extract fan before a big event rather than on the day.
Questions to ask before you book
- What insurance they carry
- How VAT is shown on the quote
- When the next visit should be, and why
- What paperwork you get at the end
Aftercare tips
Good habits slow the build-up between visits. Our tips:
- Keep the grease filters clean and fitted
- Get a noisy fan checked rather than slowed down
- Make sure staff know who to call if the fan fails
- Write down when the fan misbehaves
If the fan had grease on it, the rest of the system almost certainly does too. A full TR19® clean deals with the canopy, ductwork and fan together and you get a TR19 certificate and photo report afterwards.
Regular TR19 cleaning includes the extract fan. A clean impeller stays in balance and that means less wear.
Common questions in Millwall
Do you work at weekends in Millwall?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Millwall needn’t be disturbed. Just call 0345 646 2711 or email us with your opening times and we will plan around them.
Which council inspects kitchens in Millwall?
The local authority for Millwall is Tower Hamlets council, and its environmental health team does the inspecting. Inspections are risk-based, so a visit can come at any time, including the week a fan stops.
What do you do to protect the area?
We cover floors and nearby surfaces with sheeting before we start, and anything we remove is contained. Before we leave, we tidy up and clean down.
Do you work in Millwall?
Yes. Millwall is part of the area we cover, as part of our area across London and the South East.
Can you repair a fan rather than replace it?
That depends on what we find. We diagnose first and tell you whether a repair is realistic, then send you a fixed quote.
Is it worth cleaning the extract while you’re fixing the fan?
Doing both together is often sensible. A TR19 clean covers the canopy, plenum, ductwork and fan and comes with a TR19 certificate and photo report.
How much does an extract fan repair cost?
Every fan job is priced once we know the fault. A belt and a new fan are very different jobs, so phone us on 0345 646 2711, or email photos and we will arrange a diagnosis.
How much notice should we give?
That depends on the slot you want and the size of the job. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.
Multi-site and managed buildings
We regularly work with managing agents. Tell us the site, the work and the access arrangements, and we’ll send a fixed quote.
Records are where multi-site compliance often slips. Each visit ends with a dated report and photos, so you can show an insurer or inspector what was done at each site.

Why deal with it now?
A fan that’s running slowly isn’t clearing the kitchen properly. Staff work in hotter, steamier air and grease has more chance to settle on surfaces and in the duct. Choosing the date yourself beats having a fault choose it for you.
We do not list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll talk you through it.

When a fan fails in Millwall
Food Standards Agency records list about 617 cafés, restaurants and staff canteens and about 218 takeaways and sandwich shops in and around Millwall, up to about a mile and a half out. A kitchen with a dead extract fan gets hot and smoky fast, and kitchens like these feel it at once. London extract fans are often at the end of long duct runs, on roofs or in basements. In Millwall, food businesses are inspected by environmental health officers from Tower Hamlets council. Food hygiene rules expect food premises to have suitable and sufficient ventilation. A kitchen without a working fan has a problem to fix quickly.
If you run a kitchen close to Deptford station and the extract fan is getting noisy, a planned repair after closing beats a breakdown at the rush. If you run a school kitchen, at a school such as Harbinger Primary School or nearby, a fan that’s getting noisy is best repaired in the holidays before it fails in term.
