Grease filter exchange for sites in Rush Green

The process

We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes a few minutes per canopy, longer for a large kitchen with several canopies. The timing of a visit to Rush Green is set by you, and the travel is our side of the planning.

  1. We look at the canopies and the condition of the filters.
  2. Any damaged or missing filters are noted.
  3. Greasy filters are swapped for clean ones.
  4. We check the filters are seated and the canopy is ready to use.
  5. Anything that needs attention, such as a greasy plenum, is pointed out.

Getting ready for the visit

  • Tell us about site rules, permits or sign-in
  • Let us know about parking and loading
  • Tell us the best time to work, such as after service or at a weekend

Grease filter exchange for kitchens and businesses in Rush Green

Cleaning filters by hand takes staff time and is easy to put off. With a filter exchange, we bring a clean set and take the dirty one away and the canopy is refilled straight away. If you are dealing with bent or damaged filters that don’t sit properly and grease filters clogged with grease, we can help, from restaurants and pubs, mesh filters and island canopies onwards.

In a small place like Rush Green, kitchens are often in older or extended buildings, with long single-storey duct runs, where grease settles in the flat sections. Access, parking and timings are agreed before the day.

The sign-off is always in writing: a written report, dated and illustrated with pictures, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

Rush Green: your questions answered

Will you come out to Rush Green?

Yes, we work in villages as well as towns, and Rush Green is covered. Just mention lanes, gates or anything else about the site when you book.

Who would carry out a food hygiene inspection at a kitchen in Rush Green?

The local authority for Rush Green is North Hertfordshire council, and its environmental health team does the inspecting. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.

Do you have insurance?

Yes. We carry full insurance and have been trading since 2009.

How regularly do grease filters need exchanging?

It varies from kitchen to kitchen. The schedule is based on how heavily you cook and can change if your kitchen gets busier.

What does grease filter exchange cost?

Pricing depends on the kitchen, so we quote once we know your filters and schedule. We give you a fixed quote before the service starts.

Can we book visits on a schedule?

Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. The report from each visit recommends the next date.

Do you work with multi-site operators?

Yes. Our area covers London and the South East, so we can schedule a run of sites as one programme. Every site has its own report.

Will I get paperwork for my records?

Yes, always. The report is dated and includes pictures, and TR19® Grease cleans come with a certificate through the BESCA VHE portal. File it with your fire safety records.

What your team can do, and what needs us

If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We will take a look and send you a fixed quote.

Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.

Looking after it afterwards

Here’s the after-treatment advice, in brief:

  • Do not refit a filter that’s bent
  • Book full TR19 cleans alongside filter changes
  • Keep the extract on whenever the range is in use
  • Keep canopy surfaces wiped down

Your team carries on as normal, without the filter washing. Make sure we can reach the canopy on exchange day and tell us if service times change.

If filters are already dripping, they’re overdue. A clean set right away cuts the grease in the canopy, and it’s worth checking the plenum too.

Landlords, agents and facilities managers

Multi-site operators often want one contractor and one number. We cover South East England and London, so a run of sites can go into one programme and kept on a regular cycle.

Facilities teams in offices, schools and healthcare sites book us too in Rush Green and across Hertfordshire. Work can be phased by floor, building or site to keep disruption down.

Different parts, different methods

The plenum

Clean filters reduce the grease reaching the plenum, but it still needs cleaning as part of TR19.

School, care home and staff kitchens

For kitchens closed in the holidays, visits can be timed around term or rota, keeping the filters ready for the busy weeks.

What affects the quote in Rush Green

Sites vary more than people expect. What affects the quote:

  • The condition we find in the survey
  • The times the site is available
  • Site rules, permits and inductions
  • How big the system is

The cost depends on the size of the system, the condition it’s in and how easy it is to reach. You get a fixed price before work begins, so you know where you stand.

Helping us quote

Photos and a few facts are often enough to price the work. Useful things to send:

  • The postcode and the type of business
  • The paperwork from the last visit, if you have it
  • Any access panels or hatches you can see
  • Problems your staff have spotted

There’s no standard price list, because no two systems are the same. Instead, we look at your site first, from pictures or a survey, and then send you a fixed quote. To start, call us on 0345 646 2711 or drop us a line.

Why it’s worth doing now in Rush Green

In Rush Green, as everywhere, a filter service is not a substitute for TR19 cleaning. They do help keep the system in better shape between cleans, and that shows when the next clean comes round. In a place like Rush Green, ductwork and fans are easy to forget until something goes wrong.

The price reflects the work, not guesswork. That is why we survey first, from photos or on site, and why the quote is fixed before work begins.
