Grease filter exchange for sites in Gadebridge

How we handle grease filter exchange in Gadebridge

Washing filters in the kitchen sink is messy and easily missed on a busy week. An exchange service means clean filters arrive and greasy ones leave, so the canopy is never left without filters. Common call-outs are for gaps where filters have been removed and smoke and heat lingering under the hood, on restaurants and pubs, baffle filters and mesh filters.

In a smaller place like Gadebridge, the kitchens with extract systems are more likely to be a pub, a café, a takeaway or a school or care home kitchen than a big restaurant. Quieter kitchens still collect grease in the duct, just more slowly, so the interval is set by hours of use and grease readings.

It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we are fully insured.

Common questions in Gadebridge

Do you do school kitchen extract cleaning in Gadebridge in the summer holidays?

Yes. Half-terms and the summer break are the natural time for school work. Around Gadebridge, the Food Standards Agency lists about 20 schools and colleges with registered kitchens within a mile and a half or so. Tell us your holiday dates and we will book the visit for when the site is empty.

Do you work overnight in Gadebridge?

Yes, nights and weekends are routine for us. The work in Gadebridge can fit around your hours. Let us know the hours you’re closed and we will book within them.

Do we need to close while you work?

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.

How much notice should we give?

The more notice, the better, particularly for night and weekend visits. We typically quote within one working day, and emergencies are covered by our 24/7 line.

Do you have a 24/7 line?

Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we will talk you through the next steps.

What happens to the dirty filters?

Yes. The dirty filters are taken away for cleaning and the clean set stays in the canopy.

Where does the waste go?

It’s contained and taken away. Grease, debris and waste water are collected as the work goes on, so it does not spread.

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 the visit works

On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool before we start, and floors and nearby surfaces are sheeted. On site, it takes anything from a few minutes to an hour or so, depending on the number of filters. Because the survey comes first, a visit to Gadebridge can usually be finished without a second trip.

  1. We record the number, size and type of your filters.
  2. An exchange schedule is agreed to suit your cooking.
  3. On each visit, we remove the greasy filters.
  4. A clean set is fitted and checked for gaps.
  5. The dirty filters leave with us and the next visit is booked.

Getting ready for the visit

  • Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
  • Make sure equipment near the work can be switched off and left to cool
  • Agree a time when the area can be out of use

Do you need grease filter exchange in Gadebridge?

The type of cooking matters. Fryers, grills and woks load filters faster than ovens and steamers so no single schedule suits every kitchen.

Common reasons sites call us include:

  • A canopy that drips grease
  • Filters so greasy the air can barely pass
  • Missing filters in the filter bank
  • Smoke and heat lingering under the hood

A hospital like Hemel Hempstead Hospital, about 1.2 miles south-east, is the kind of site where a kitchen may cook for patients, staff and visitors all day.

Our hiring checklist

What staff can safely do

If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.

Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.

Grease, kitchens and Gadebridge

Food Standards Agency records include about 27 pubs and bars and about 3 hotels and B&Bs in and around Gadebridge, up to about a mile and a half out. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Hertfordshire Fire and Rescue Service covers Gadebridge. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. Kitchens in Gadebridge get their food hygiene inspections from Dacorum council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Keeping each certificate and photo report on file helps show the extract is looked after.

School kitchens, at schools like Galley Hill Primary School and Nursery for example, are normally cleaned in the holidays so no lunches are lost. Where a hall near St Alban's Church, or anywhere in Gadebridge, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

Aftercare tips

No system stays clean for ever, but care slows the build-up. A few tips:

  • Keep filter exchange and TR19 cleaning on the same plan
  • Mention it if the kitchen gets busier
  • Keep the canopy clear for exchange visits
  • Keep every filter in place during service

The canopy looks cleaner and the air moves better right away. Keep the extract running while you cook so they catch grease as intended.

Saturated filters let more grease through. A regular cycle keeps the rest of the system cleaner between full cleans.

Landlords, agents and facilities managers

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 to a regular schedule.

If you look after several sites, we can schedule visits across all of them on one quote. Each site gets its own report and pictures, so each one has its own record.

How the job changes from site to site

Busy restaurant and pub kitchens

In a busy kitchen, filter washing is easy to skip. An exchange service takes it off the rota.

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 Gadebridge

There’s no set price list, because no two systems are the same. What we look at:

  • Travel, parking and unloading
  • The condition we find in the survey
  • Any permits to work or inductions
  • A single visit or a regular plan

When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account and give you a fixed price before we start.

Helping us quote

When you call or email, it’s useful to have:

  • Wide photos of the system and the area around it
  • Your last certificate, test record or report
  • How we’d reach plant on a roof or in a plant room
  • Where the site is and what kind of site it is

If you need grease filter exchange in Gadebridge, give us a ring on 0345 646 2711 or send us an email. Tell us what kind of premises it is and when it’s open, and send photos or your last report if you can. We usually send a fixed quote within one working day.
