Keeping the system healthy

After the visit, a few habits help the work last:

  • Never cook with the extract switched off
  • Look out for drips from the canopy
  • Don’t refit a filter that is bent
  • Keep filter exchange and TR19 cleaning on the same plan

Your next visit is scheduled before we leave. If cooking increases, we can change filters more often to match.

Saturated filters let more grease through. A regular cycle keeps the rest of the system cleaner until the next TR19 clean.

Grease filter exchange for kitchens and businesses in Waltham

Whether your canopy has baffle or mesh filters, they load up with grease. Once they’re clogged, airflow drops and the fan has to work harder. A steady cycle of clean filters keeps extraction strong. If you are dealing with hand-washed filters that still look greasy and drips falling from the filters onto equipment, we can put it right, from wall canopies, mesh filters and school and hospital kitchens onwards.

Rural kitchens often have long, low duct runs through a roof space or along an outside wall, where grease settles in the flat sections. We agree access and timings in advance.

Accreditations are easy to claim and worth checking. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

What staff can safely do

When your team notices a problem 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.

For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.

Do you need grease filter exchange in Waltham?

The type of cooking matters. Fryers, grills and woks load filters faster than ovens and steamers, so the right exchange interval varies.

These are the problems we see most often:

  • Staff short of time to wash filters
  • Bent or damaged filters that do not sit properly
  • Filters that come out of the sink still dirty
  • Filters so greasy the air can barely pass

If you run catering at a healthcare site, such as a hospital like Kent and Canterbury Hospital about 5.5 miles north-east, the extract may need cleaning more often than a part-time kitchen.

Questions to ask before booking

Kitchen extracts in Waltham

Waltham sits within the area of Kent Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel. Food hygiene inspections in Waltham are the job of Canterbury City council’s environmental health team. 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.

If you run a church or community hall kitchen, near Church of St Bartholomew or elsewhere in Waltham, its extract still collects grease from every lunch and event.

What affects the cost of grease filter exchange

The price is fixed before any work begins. It’s based on:

  • The condition of the system
  • Site requirements such as sign-in and permits
  • The scale of the work
  • How many systems or sites are involved

Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you’re not sure what’s needed, give us a ring on 0345 646 2711 or use the quote form and we will give you an honest view and a fixed quote.

What to send for a quote

Many jobs can be priced from photos and some basics. Send what you can of the following:

  • Any symptoms, from odd noises to smells or leaks
  • The times we could work without disrupting the site
  • A few general shots of the system
  • Any access panels or hatches you can see

Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before any work starts.

Why act early in Waltham

For any kitchen in Waltham, filters cannot stand in for a full TR19 clean. They do help keep the system in better shape between cleans, and that shows when the next clean comes round. A planned visit to Waltham is easier to arrange than an emergency callout.

Several systems or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at and we will price it together.

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. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes less than an hour in most kitchens. We agree a date with you, plan the drive to Waltham and turn up when the site is quiet.

  1. We record the number, size and type of your filters.
  2. We set the interval with you.
  3. On each visit, we remove the greasy filters.
  4. A clean set is fitted and checked for gaps.
  5. We take the greasy set away and confirm the next date.

How to prepare

  • Mention any parking or loading restrictions
  • Let us know about permits to work or site inductions
  • Agree a time when the area can be out of use

Advice

For landlords and multi-site operators

The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.

Running several sites is easier with one contractor. We cover South East England and London, so a run of sites can go into one programme and kept on a regular cycle.

Your questions about grease filter exchange in Waltham

Do you cover smaller places like Waltham?

Yes. Villages and rural sites across the South East are part of our work, Waltham included. Photos of the system and directions to the site help us plan the visit.

Who enforces fire safety at workplaces in Waltham?

Waltham is in the area of Kent Fire and Rescue Service. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.

How do you protect the area?

We cover floors and nearby surfaces with sheeting before any work starts, and waste is contained as we go. Before we leave, we tidy up and clean down.

What types of premises do you cover?

Any site with a kitchen or a ventilation system to look after, from a small pub to a hospital. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.

What paperwork should we keep on file?

Anything that proves the system is maintained: reports, certificates, photos and your own cleaning or check logs. One maintenance log per site keeps it simple.

Do you handle baffle and mesh filters?

Baffle and mesh filters are both covered. The first step is recording what you have and set up the service around them.

Does a filter exchange replace TR19 cleaning?

No. Clean filters help keep grease down, but the ducts and plenum still need cleaning at the right interval.

What’s TR19?

TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
