Part by part

School, care home and staff kitchens

Even kitchens with fixed meal times build up grease, though often more slowly.

Mesh filters

Mesh filters use layers of metal mesh to trap grease. They clog quickly in a busy kitchen and need frequent attention.

Grease filter exchange for kitchens and businesses in Todd's Green

The filters in the canopy are the first thing cooking vapour meets. Their job is to stop grease getting further into the system and they do it best when they’re clean. With grease filter exchange, clean filters replace greasy ones at regular intervals. The work covers mesh filters, island canopies and baffle filters, and people most often call us about filters left unwashed on busy weeks and filters so greasy the air can barely pass.

Work in a small place like Todd's Green 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.

Every visit ends with a written report and pictures, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Signs you need grease filter exchange in Todd's 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.

These are the problems we see most often:

  • Filters that leave gaps in the canopy
  • A greasy plenum behind the filters
  • Filters left unwashed on busy weeks
  • Grease left in baffles after washing

Healthcare kitchens, like those at hospitals such as Lister Hospital (about 0.6 miles east), often cook for long hours, which puts them in BESA’s heavier-use bands.

Our hiring checklist

What affects the cost of grease filter exchange

The diagnosis comes before the price. We look at:

  • The scale of the work
  • What state the system is in
  • When the work can happen, such as evenings, overnight or weekends
  • A single visit or a regular plan

Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we will go through it with you.

What to send for a quote

To help us quote quickly, send us:

  • Your last certificate, test record or report
  • The roof, plant room or outside wall the system runs to
  • When the site is open and when it’s quiet
  • Any symptoms, from odd noises to smells or leaks

What staff can safely do

For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.

Staff cleaning doesn’t 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.

Kitchen extracts in Todd's Green

Food Standards Agency data counts about 33 restaurants, cafés and works canteens and about 21 takeaways in and around Todd's Green, up to about a mile and a half out. Swapping filters on a schedule keeps kitchens like these drawing air properly. Kitchens in Todd's Green get their food hygiene inspections from Stevenage council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Keeping each certificate and photo report on file helps show the extract is looked after. The fire and rescue service for Todd's Green is Hertfordshire Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.

A hall kitchen that only cooks for events, whether near Church of St Mary the Virgin or elsewhere in Todd's Green, still needs its extract cleaned, just less often. Term dates shape school work: for a school like The John Henry Newman School, an extract clean fits neatly into a half-term or summer break.

Todd's Green: your questions answered

Which environmental health team covers Todd's Green?

Kitchens in Todd's Green are inspected by Stevenage council’s environmental health officers. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.

Do you work in villages like Todd's Green?

Yes, we work in villages as well as towns, and Todd's Green is covered. Let us know about access, parking and anything unusual about getting there when you book.

What types of premises do you cover?

All kinds of commercial and public premises: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. We fit the work around how the site operates.

Are you insured?

Yes, fully. We also hold CHAS and SafeContractor for clients who vet their contractors.

Does a filter exchange disrupt service?

Visits are short, and we can come before or after service. There’s no wait between removing and refitting.

What accreditations do you have?

CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We are fully insured and have been trading since 2009.

Will I get paperwork for my records?

Yes. It’s your proof that the work was done: a dated report with pictures, listing the work and any areas we couldn’t reach.

Can we skip TR19 cleans if the filters are changed regularly?

No, the two work together. A TR19® clean deals with the whole system, with a certificate and photo report.

What happens if it’s left?

Some kitchens in Todd's Green wash filters themselves to save the cost of a service, and it works when it’s done well and never skipped. When it does not happen reliably, an exchange makes it automatic. It’s simpler to plan the work at Todd's Green now than to arrange it in a hurry later.

Combining work into one visit or one programme can make for a more efficient booking. Tell us about everything you’d like looked at and we will price it together.

What happens on the day

The visit has three parts: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, while signing off means the written report and photos. Most of the time goes on the work itself, which takes anything from a few minutes to an hour or so, depending on the number of filters. A few photos of the system help us make the most of a visit to a place like Todd's Green.

  1. We start by noting how many filters you have and what type they are.
  2. Together we set how often the filters should be changed.
  3. On each visit, the dirty filters come out of the canopy.
  4. We fit clean filters and check they sit snugly in the housing.
  5. We flag any damaged filters or anything wrong with the canopy.

Getting ready for the visit

  • Tell us the best time to work, such as after service or at a weekend
  • Clear loose items from the work area
  • Let us know about parking and loading

How to get a quote

Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.

Managing agents and facilities teams in Todd's Green

We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.

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