Kitchen extract cleaning in Farnham

Commercial kitchen extraction cleaning in Farnham

The canopy over the range is only the start of a kitchen extract system. Behind it sit the plenum and grease filters, then the ductwork, risers, extract fan and discharge, and each part collects grease. Our clean follows the air from canopy to discharge, cleaning to BESA TR19® Grease. Common call-outs are for grease smells coming from the extract and grease dripping from the canopy or filters, across horizontal duct runs, plenums and filters and vertical risers. Some call it canopy cleaning, others extract cleaning or duct cleaning, but in Farnham, as everywhere, the insurer wants the full system cleaned, not just the hood.

Before we clean, we look at where the grease is: grease readings at set points tell us where the heaviest deposits are, and the same readings after the clean show the result.

Somewhere as small as Farnham, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Each still has a canopy and duct that collect grease, whatever the size of the place.

Good records are part of the job. You get a written report with pictures after every visit, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

How we price kitchen extract cleaning

Every site gets its own quote. These are the things that affect it:

  • Whether several sites go on one quote
  • Working hours and out-of-hours timing
  • Access, including roofs, risers and ceiling voids
  • Any permits to work or inductions

No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all make a difference.

Helping us quote

A few details help us quote accurately. When you get in touch, it helps to send:

  • Where the plant sits or the system leaves the building, such as a roof or outside wall
  • Photos showing the whole system and its surroundings
  • Close-ups of filters, grilles, hatches or access panels
  • Anything you’ve noticed, such as smells, noise, drips or poor airflow

Want a quote for kitchen extract cleaning? Please phone us on 0345 646 2711 or send us an email and tell us about the site. We will explain what we’d do and send a fixed quote before you commit to anything.

What your team can do, and what needs us

Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That is our job.

Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.

What we do, step by step

Everything the job needs comes with us, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. The visit takes anything from a few hours to a full night, depending on the size of the system. Photos of the system and how to reach it help us plan a visit to Farnham.

  1. You send photos or we visit, and the system is surveyed from canopy to discharge.
  2. We take grease readings at set points and give you a fixed quote.
  3. On the night, the equipment is off and cool and the kitchen is sheeted.
  4. We work through the system from the canopy to the fan and discharge.
  5. We re-test, photograph and send your certificate and photo report.

Getting ready for the visit

  • Make sure equipment near the work can be switched off and left to cool
  • Clear the space around the work
  • Let us know when the site is closed or quiet

How to get a quote

Quoting starts with a diagnosis, either from photos and details you send or from a site visit. After that, you get a fixed price for the work so you know the cost before any work starts.

Advice

Part by part

Canopy and plenum

Behind the grease filters sits the plenum, which daily cleaning never reaches. We take the filters out and clean the plenum and housing thoroughly.

Ductwork and risers

Vertical risers carry the air up through the building, and grease runs down their walls and pools at the base. Access panels along the riser let us clean it in sections.

Farnham kitchens: local notes

The FSA’s food hygiene register shows about 3 restaurants, cafés and canteens in and around Farnham, up to about a mile and a half out. Wherever food is cooked under a canopy, the extract above it gathers grease and needs cleaning on a schedule. Kitchens in Farnham get their food hygiene inspections from Uttlesford council. 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. Hertfordshire Fire and Rescue Service covers Farnham. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.

If your kitchen is in a listed or historic building, like the houses around Farnham (Much Hadham Palace is about 4.2 miles south-west), fitting access panels needs care. Church and community hall kitchens, near Church of St Mary the Virgin or anywhere around Farnham, are easy to forget, but their extracts collect grease like any other.

Farnham is about 2 miles north of Bishop's Stortford, in Hertfordshire. From the centre of Farnham to the outskirts, we cover kitchen extract cleaning for every kind of premises, from small sites to large estates. We cover 381 places across Hertfordshire, from busy centres to quieter spots. We also work in Chelmsford, around 19 miles away.

Common problems we fix in Farnham

Grease in the extract matters because it burns. Flames from a pan or grill can be pulled into the canopy by the fan, and once grease in the duct catches, fire can spread through the building’s ductwork. That is why controlling extract grease belongs in the fire risk assessment.

These are the problems we see most often:

  • A system with no record of a TR19 clean
  • Proof of cleaning requested by an insurer
  • Stale cooking odours from the system
  • Poor airflow at the canopy

If you run catering at a healthcare site, such as a hospital like Herts and Essex Hospital about 2.8 miles south-east, the extract may need cleaning more often than a part-time kitchen.

Choosing a duct cleaning contractor

Managing agents and facilities teams in Farnham

Managing agents often deal with us directly. Send the address, what’s needed and how access works, and we will send a fixed quote.

When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side, and the report can go to both.

Aftercare tips

Looking after the system between visits is straightforward, and it helps at the next visit:

  • File each certificate with the fire risk assessment
  • Keep grease collection points emptied
  • Refit filters properly after cleaning
  • Wash or exchange the filters often

When the clean is finished, grease readings are taken again at the same points, giving you before and after readings alongside the photos. Your TR19 certificate is then issued through the BESCA Vent Hygiene Elite portal.

Wipe the canopy down regularly and empty grease troughs or collection points. It won’t replace a TR19 clean, but it slows what reaches the duct.

FAQs for Farnham

Who carries out food hygiene inspections in Farnham?

The local authority for Farnham is Uttlesford council, and its environmental health team does the inspecting. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.

Do you work overnight in Farnham?

Yes, evening, overnight and weekend work is normal for us. Your customers, staff or residents in Farnham needn’t be disturbed. When you give us a ring on 0345 646 2711 or drop us a line, mention when the site is quiet.

What do you need from me for a quote?

A short description and a few photos plus the address and your hours. We’ll ask for anything else we need.

What’s the right cleaning interval for a kitchen extract?

It depends on how many hours a day the kitchen cooks. Heavy use of 12 to 16 hours a day calls for a clean at least every 3 months under BESA guidance, and lighter use less often. Your report gives a recommended next clean date.

How much notice should we give?

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 insurers need proof of extract cleaning?

Because a dirty extract can spread a fire through a building. Many insurers require TR19 cleaning, and may refuse or reduce a claim without proof, so keep every certificate.

Which sectors do you work in?

Any commercial site with kitchens or ventilation, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.

Do you offer maintenance contracts?

Yes. Plans on a 3, 6 or 12-monthly cycle are available, to suit the system and how it’s used.
