When to call us in Forty Green

Missing filters are more common than you’d think. Every gap in the filter bank lets grease straight into the plenum and on into the ductwork.

The symptoms we’re asked about most include:

  • Missing filters in the filter bank
  • Bent or damaged filters that don’t sit properly
  • Grease left in baffles after washing
  • Staff short of time to wash filters

Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Forty Green is Hospital of St John the Baptist, about 3.5 miles west.

Our hiring checklist

Grease filter exchange in Forty Green, done properly

A filter that doesn’t sit right lets grease straight past. Bent, damaged or missing filters leave gaps and every filter is checked when we swap them. We point out any that need replacing. If you are dealing with a greasy plenum behind the filters and gaps where filters have been removed, we can put it right.

Work in a small place like Forty Green starts with a call to agree access and timings, and the clean itself is the same full TR19® job as in any town: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.

Nothing is signed off by word of mouth: a dated report with pictures of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

What happens on the day

Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes a short visit, depending on how many filters the canopies hold. Somewhere like Forty Green, lanes, gates and parking are worth mentioning in advance.

  1. First, we check the canopies and the filters in them.
  2. We note any filters that are bent, damaged or missing.
  3. Greasy filters are swapped for clean ones.
  4. The filters are checked for fit before we go.
  5. Anything that needs attention, such as a greasy plenum, is pointed out.

How to prepare

  • Allow time for equipment near the work to be turned off and cool down
  • Tell us where we can park and unload
  • Clear the space around the work

FAQs for Forty Green

Can the work in Forty Green be done at night or at weekends?

Yes, nights and weekends are routine for us. Your customers, staff or residents in Forty Green needn’t be disturbed. Tell us your opening hours when you ask for a quote.

Who carries out food hygiene inspections in Forty Green?

That’s Buckinghamshire council, whose environmental health officers carry out food hygiene inspections in Forty Green. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.

What does TR19 mean?

BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t legislation, but it’s the standard people check against.

Do you deal with bent or broken filters?

Each filter is looked at when we exchange. Any that are bent or damaged are flagged, because gaps let grease into the plenum.

Is there a cleaning option for the filters we have?

Yes, filter cleaning is available. The first step is looking at the filters you have because bent or damaged ones may need replacing.

Do we lose a day’s trading?

Not usually. We need the work area to ourselves while we’re on site, so the visit goes in a quiet slot.

Will I get paperwork for my records?

Yes. It’s the record insurers and inspectors ask to see: a dated report with photos, listing the work and any areas we couldn’t reach.

How much notice do you need?

It depends on the time you need and how big the job is. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.

Grease filter exchange in Forty Green: the local picture

The FSA’s food hygiene register includes about 11 pubs and bars across Forty Green and its immediate surroundings (about a mile and a half). A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Forty Green is covered by Buckinghamshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. In Forty Green, food businesses are inspected by environmental health officers from Buckinghamshire council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A dated certificate in the maintenance file answers the question before it’s asked.

A hall kitchen that only cooks for events, whether near Church of St Michael and All Angels or elsewhere in Forty Green, still needs its extract cleaned, just less often. School kitchens, at schools like Holtspur School & Pre-School for example, are usually cleaned in the holidays so no lunches are lost.

How the job changes from site to site

School, care home and staff kitchens

For kitchens closed in the holidays, visits can be timed around term or rota so the filters are clean when cooking picks up.

The plenum

Heavy grease in the plenum often follows clogged or missing filters or that the next TR19 clean is due.

Aftercare tips

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

  • Do not refit a filter that’s bent
  • Never cook with the extract switched off
  • Never leave gaps in the filter bank
  • Let us know if your cooking hours increase

The canopy looks cleaner and the air moves better straight away. Keep the extract running while you cook so the filters do their job.

Filters that are left too long stop protecting the system. A regular cycle keeps the rest of the system cleaner until the next TR19 clean.

What staff can safely do

Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.

Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.

Landlords, agents and facilities managers

Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We’re happy to deal with either side and send the paperwork to whoever needs it.

We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we’re happy to quote for all of it.
