Extract fan cleaning near Sepham Heath

Extract fan cleaning in Sepham Heath, done properly

A fan never collects grease in a neat, even layer. Heavier deposits on some blades throw the impeller off balance, leading to vibration, noise and strain on the motor and bearings. A thorough clean removes the cause. Typical jobs include a fan coated in grease inside its housing and rough running from the extract fan, across centrifugal fans, fan housings and discharge points.

Work in a small place like Sepham Heath starts with a call to agree access and timings, and the clean covers the whole system, as it would anywhere: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.

We have been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

How it works

The visit has three parts: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with pictures. The middle part takes longest, and that takes a few hours where there are several fans or heavy deposits. In a small place like Sepham Heath, the journey is planned ahead and the visit arranged around the site’s hours.

  1. Diagnosis first: we look for grease, noise and vibration.
  2. With the fan isolated, the housing is opened.
  3. Each blade is cleaned so the impeller runs evenly.
  4. We clean the casing, the outlet and around the motor.
  5. The fan goes back into service with a report on its condition.

Preparing for the visit

  • Make sure equipment near the work can be switched off and left to cool
  • Arrange a key holder or contact on site
  • Tell us about site rules, permits or sign-in

Why it’s worth doing now in Sepham Heath

Cleaning the fan in Sepham Heath now is a short job: the work takes an hour or two for one fan, longer when it’s hard to reach. Waiting adds vibration, wear and a harder clean. Systems in rural buildings are often out of sight and out of mind.

Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you’re unsure, call 0345 646 2711, or email photos for straight advice and a fixed quote.

How the job changes from site to site

Wall fans

With little duct before them, wall fans collect grease fast. They may need cleaning as often as the canopy, which grease readings will show.

Inline duct fans

Some fans are built into the duct itself. They’re reached through access panels or by opening the casing, once they’re isolated.

What your team can do, and what needs us

Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.

A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.

Sepham Heath questions

Can you get to a site in Sepham Heath?

Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.

Can the work in Sepham Heath be done at night or at weekends?

Yes, we can come after you close and finish before you open. That way a site in Sepham Heath doesn’t have to lose a day’s trading. Your opening times are the first thing we ask for.

What types of premises do you cover?

Commercial premises of every kind: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. Work is timed around how each site runs.

Do we lose a day’s trading?

Not normally. We work when the area is out of use, such as evenings, overnight, early mornings or weekends, so the site can carry on as normal.

Does the law say we must follow TR19?

No, not in itself. Insurers, fire officers and EHOs look to TR19® as the benchmark, and many insurers ask for proof of cleaning to it. The legal duty sits in the Regulatory Reform (Fire Safety) Order 2005, which applies in England and Wales.

What’s TR19?

BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t legislation, but it’s the standard people check against.

How much does extract fan cleaning cost in Sepham Heath?

There’s no set price, as it depends on the job: how big it is, what state it’s in, how we reach it and the working hours. We fix the price before any work starts.

What if parts of the system can’t be reached?

We never leave them off the paperwork. You will know exactly which parts weren’t reached and why, along with a quote to put access in.

Honest limits

Before you book, it helps to know what’s not included:

  • A dirty duct upstream of the fan

If in doubt, call 0345 646 2711 or drop us a line and we will say what we think.

Parts of the system we cover

  • In-line fans
  • Axial fans
  • Centrifugal fans
  • Discharge points

Common problems we fix in Sepham Heath

Grease on a fan is a fire risk, in Sepham Heath as anywhere. If grease in the duct catches, the fan and its housing can feed the fire and an overworked motor runs hotter.

Keep an eye out for these warning signs:

  • An extract fan with no cleaning record
  • An extract fan that vibrates or rattles
  • A fan that no longer moves enough air
  • Hot, greasy smells near the fan

Volunteers running a hall kitchen near Otford Lane Mission Church, or anywhere in Sepham Heath, may not know when the extract was last cleaned, and a grease test settles it.

Questions to ask before you book

  • What hours they’ll be on site
  • What paperwork you get at the end
  • Proof of accreditation you can verify
  • How they set the interval to the next visit

Multi-site and managed buildings

We also work for facilities teams across offices, schools and healthcare across Kent. Larger estates can be phased building by building to keep disruption down.

Keeping records across a portfolio is half the battle. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.

Extract fan cleaning in Sepham Heath: the local picture

There are about 3 restaurants, cafés and works canteens within 1.5 miles or so of the middle of Sepham Heath, according to the Food Standards Agency’s register. Grease builds up on fan blades and housings in kitchens like these, unbalancing the impeller. Sepham Heath sits within the area of Kent Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract. Environmental health officers from Sevenoaks council inspect food businesses in Sepham Heath. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A dated certificate in the maintenance file answers the question before it’s asked.

Healthcare kitchens, like those at hospitals such as Sevenoaks Hospital (about 3.1 miles south-east), often cook for long hours, which puts them in BESA’s heavier-use bands. Term dates shape school work: for a school like Halstead Community Primary School, an extract clean fits neatly into a half-term or summer break.
