West Sussex · Extract fan repair and replacement
Extract fan repair and replacement in Merston, West Sussex
We cover Merston for extract fan repair. Out-of-hours visits, a fixed quote and a written report with photos on every job.
- An extract fan that rattles or knocks
- A worn or slipping fan belt
- A dead fan motor
What happens if it’s left?
Some kitchens run a noisy fan on a lower speed to cut the noise. That reduces extraction without fixing anything while the underlying wear continues. A proper diagnosis in Merston gets to the real cause. In a place like Merston, ductwork and fans are easy to forget until something goes wrong.
The cost 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.

Extract fan repair for kitchens and businesses in Merston
Before anything is ordered, we diagnose. The motor, drive, impeller, bearings and mounts are all checked and the speed control too. Then you’re given a fixed quote for the repair or the replacement. Typical jobs include a fan running too slowly to clear the kitchen and a fan that won’t start at all, on roof and wall fans, kitchen extract fans and belts and pulleys.
In a village or hamlet like Merston, the kitchens with extract fans are few, wherever there are any. When one fails, the cooking stops, and our 24/7 emergency line covers rural addresses too.
Good records are part of the job. Each visit is written up with photos, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

When something else is needed
A few issues sit outside what this work can do:
- Wiring and supply faults beyond the fan itself
- Grease throughout the ductwork, which needs a full TR19 clean
- Gas interlock faults that a Gas Safe registered engineer must deal with
If in doubt, phone us on 0345 646 2711, or send details by email and we’ll say what we think before you book.

Extract fan repair in Merston: local notes
The FSA’s food hygiene register shows about 7 restaurants, cafés and works canteens in Merston and the streets around it, up to about 1.5 miles out. Wherever they cook under a canopy, a failed extract fan stops the kitchen. Environmental health officers from Chichester council inspect food businesses in Merston. Under food hygiene rules, a kitchen needs suitable and sufficient ventilation. A kitchen without a working fan has a problem to fix quickly. Merston is about 54 miles from central London, well within the area we cover across London and the South East. A survey and a fixed quote come first, then the visit at a time that suits you.
Holidays are the time to replace a tired kitchen fan at schools such as North Mundham Primary School, rather than mid-term. Hall kitchens near Church of St Giles, or anywhere around Merston, often use their fans only now and then, and an idle fan can stick.
Merston is about 3 miles south-east of Chichester, in West Sussex. Whether your site is in the middle of Merston or further out, we cover extract fan repair for every kind of premises, from a single unit to a large public building. Across West Sussex, we cover 371 places, Merston among them. Portsmouth is in our area too, around 15 miles away.

If your site is just outside Merston, we cover Runcton (1 mile south-west), Colworth (1 mile east), Oving (1 mile north), North Mundham (1 mile west) and Lagness (1 mile south). We also work in nearby towns such as Worthing (15 miles east), Bognor Regis (3 miles south-east), Chichester (3 miles north-west), Selsey (6 miles south), Littlehampton (9 miles east) and Emsworth (9 miles west).
Landmarks near Merston
We work in commercial kitchens and buildings around Chichester High School For Girls and the streets around them.

Nearby you’ll also find The Chichester City Museum (2.3 miles north-west) and St Richard's Hospital (2.3 miles north-west).
What the work involves, part by part
Direct-drive fans
Direct-drive fans have the impeller mounted straight on the motor. There are no belts, so faults tend to be in the motor, bearings or impeller.
Fan controls
Every fan has controls, from a speed controller to an isolator. A control fault can leave the fan dead or stuck at one speed.

Multi-site and managed buildings
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.
If you look after several sites, we can schedule visits across all of them on one quote. Every building has its own written report, so records stay tidy.
Merston: your questions answered
Who do I call if an extract fan fails in Merston?
Merston is covered, and our emergency callout runs 24/7. Ring 0345 646 2711 at any hour and describe the fault. If you can, stop cooking until the fan is checked.
Do you work at weekends in Merston?
Yes, nights and weekends are routine for us. It means the site in Merston keeps running as normal. Tell us your opening hours when you ask for a quote.
What is TR19?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
What if parts of the system can’t be reached?
They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, which we can install.
What makes a kitchen extract fan rattle or whine?
Grease on the blades throws the fan out of balance and that is one of the most common reasons. Bearings, belts and mountings can also be to blame.
Are you accredited?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We are fully insured and have been trading since 2009.
Does the law say we must follow TR19?
No. TR19® itself isn’t law; it’s a BESA specification. 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 do you protect the area?
By covering it before any work starts. We keep the work contained and clean down when we finish.
What we do, step by step
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool before work begins, and the area around the work is covered and protected. On site, it takes a few hours on site, depending on the fault and the access to the fan. Visits to a village like Merston are booked in advance, at a time that suits whoever runs the site.
- A visit is booked, in the evening or overnight if that suits.
- We isolate the extract and open the fan housing.
- We inspect every moving part and the fixings.
- We explain the options and quote a fixed price.
- We complete the work and check the fan runs smoothly.
Preparing for the visit
- Allow time for equipment near the work to be turned off and cool down
- Let us know when the site is closed or quiet
- Tell us about site rules, permits or sign-in
Ask for a quote
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.
Advice
Looking after it afterwards
Good habits slow the build-up between visits. Our tips:
- Book regular TR19 cleaning, which includes the fan
- Make sure the isolator and controls are easy to reach
- Do not wait for a noisy fan to stop
- Don’t cook with gaps in the filter bank
Clean filters help a repaired fan stay that way. The less grease that reaches the fan, the longer its parts last and fewer faults.
A scheduled maintenance plan keeps the whole system on a regular cycle, which means the fan is seen regularly and problems are spotted sooner.
What affects the quote in Merston
You’ll get a fixed price before any work starts. It takes into account:
- Site rules, permits and inductions
- Whether it’s a one-off visit or part of a schedule
- How easy every part is to reach
- The condition of the system
Combining work into one visit or one programme often makes better use of the time. Tell us about everything you’d like looked at and we will price it together.
