How we handle extract fan repair in South Heath
Before anything is ordered, we diagnose. We look at the motor, the belts or direct drive, the impeller and the mountings, along with the fan’s controls. Then you are given a fixed quote for the repair or the replacement. If you have a motor that trips out or overheats and poor airflow at the canopy, we can put it right.
Somewhere as small as South Heath, a kitchen extract fan might serve a pub, a school, a care home or a hall kitchen. A failed fan stops the kitchen, and emergency callout is available 24/7, villages included.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

How the job changes from site to site
Belt-driven fans
Squealing at start-up often points to a belt. We check the belt condition, tension and alignment and replaced if they’re worn.
Roof and wall-mounted fans
An external fan’s rattle can be heard outside. It’s often down to loose mounts or worn bearings.
When to call us in South Heath
Fans everywhere, South Heath included, live in a hard environment: hot, greasy, damp air for hours on end. Moisture can rust housings and fixings and eventually any fan simply wears out.
Clients typically contact us after spotting something like this:
- Poor airflow at the canopy
- A fan that will not start at all
- An extract fan that rattles or knocks
- A whining or grinding extract motor
Hall kitchens near St Mary's, or anywhere around South Heath, often use their fans only now and then, and an idle fan can stick.

When a fan fails in South Heath
Look up South Heath on the FSA’s food hygiene register and you will find about 9 cafés, restaurants and staff canteens in and around South Heath, up to about a mile and a half out. Wherever they cook under a canopy, a failed extract fan stops the kitchen. About 29 miles out from central London, South Heath is part of the South East area we work across. A survey and a fixed quote come first, then the visit at a time that suits you. It’s Buckinghamshire council that sends environmental health officers to food businesses in South Heath. Ventilation is part of food hygiene law, which expects it to be suitable and sufficient. Getting the fan running again is the priority.
If you run a school kitchen, at a school such as Great Missenden CofE Combined School or nearby, a fan that is getting noisy is best repaired in the holidays before it fails in term.

When something else is needed
We’d rather tell you now than book work that will not help, so here are the limits:
- Cooking smells reaching neighbours, which may need odour control
- Grease throughout the ductwork, which needs a full TR19 clean
- A system that needs redesigning rather than repairing
If in doubt, phone us on 0345 646 2711 or send us an email and we’ll say what we think before booking.

How we price extract fan repair
A fixed price needs a few facts first. We look at:
- The condition we find in the survey
- How many systems or sites are involved
- When the work can happen, such as evenings, overnight or weekends
- How easy every part is to reach
Working hours, access and the scale of the site can all change the price. We take each of them into account and give you a fixed price before work begins.
What we need to know
Photos let us diagnose from a distance. The most useful are:
- Photos showing the whole system and its surroundings
- The paperwork from the last visit, if you have it
- Any symptoms, from odd noises to smells or leaks
- When the site is open and when it’s quiet
Getting a quote doesn’t take long. Send a few details and pictures, and we normally reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
FAQs for South Heath
Can you come to South Heath after we close?
Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. Let us know the hours you’re closed and we will book within them.
Which environmental health team covers South Heath?
The local authority for South Heath is Buckinghamshire 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.
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 law behind it is the Fire Safety Order 2005, which applies in England and Wales.
Do you work with multi-site operators?
Yes. Tell us the addresses and what each needs and we will quote them together.
Do you work in South Heath?
Yes. We work across Greater London, Surrey, Kent, Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, and that includes South Heath.
How much time does a fan repair need?
That depends on what’s wrong, but most jobs take anything from an hour or two to a full visit, depending on the fault. We will give you a better idea once we have diagnosed it.
Is it worth cleaning the extract while you are fixing the fan?
A repair deals with the fan, not the grease in the rest of the system. If there’s grease on the fan, a full TR19® clean is worth booking, and we can arrange both.
Do you offer emergency callouts?
Yes, day and night, every day of the year. Our office is open from 8am to 6pm on weekdays, and the emergency line covers the rest.
What happens if it’s left?
Where the cooking gas supply is interlocked with the extract, a failed fan can stop the kitchen cooking. Even without an interlock, cooking without extraction is not sensible, so a failing fan is worth dealing with early. In a small place like South Heath, a system that fails can take a site out of use.
The price reflects the work, not guesswork. That’s why every job is surveyed first, and the price is agreed before we start.
