Grease filter exchange near Wouldham

Grease filter exchange for kitchens and businesses in Wouldham

Baffle filters and mesh filters both fill 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 have weak extraction at the canopy and filters that leave gaps in the canopy, we can put it right, from wall canopies, school and hospital kitchens and mesh filters onwards.

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

Think of the report as the system’s health record: a dated account with photos of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

Your questions about grease filter exchange in Wouldham

Can you get to a site in Wouldham?

Yes, smaller places are covered as well as towns. A survey first, from photos or a visit, means we arrive with the right kit.

Can you come to Wouldham after we close?

Yes, evening, overnight and weekend work is normal for us. The work in Wouldham can fit around your hours. Your opening times are the first thing we ask for.

What does TR19 mean?

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

Do you take the used filters away?

They leave with us. That’s how an exchange works: clean filters in, dirty ones out and nothing greasy left on site.

How do you protect the area?

Protection goes down first: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.

Does a filter exchange replace TR19 cleaning?

It isn’t. Clean filters help keep grease down, but the ducts and plenum still need cleaning at an interval set by risk assessment.

Do you survey before quoting?

Yes. Every job is surveyed first, either from pictures and details you send or on a site visit. Then you get a fixed quote.

Do you have a 24/7 line?

Yes. There’s a 24/7 emergency line for anything that cannot wait until a planned visit. Ring any time and tell us what’s happened.

How the job changes from site to site

Busy restaurant and pub kitchens

Kitchens that fry and grill all day load their filters fast. They often need the shortest exchange interval.

The plenum

A greasy plenum is a sign filters have been left too long, or that a full clean is due.

How we price grease filter exchange

We don’t publish a price list, because no two systems are the same. What we look at:

  • The condition of the system
  • Whether several sites go on one quote
  • The size of the system
  • One-off work versus a regular cycle

What you pay reflects the actual work. That’s why we survey first, from photos or on site, and why the quote is fixed before any work starts.

What we need to know

To speed up the quote, send us:

  • Problems your staff have spotted
  • Your last certificate, test record or report
  • The site address and the type of premises
  • The roof, plant room or outside wall the system runs to

Want a quote for grease filter exchange? Please phone us on 0345 646 2711 or email us with a few details about the site. We’ll explain what we’d do and send a fixed quote before you commit to anything.

Between visits

To keep the system working properly between visits:

  • Wipe the outside of the canopy as part of daily cleaning
  • Watch for grease drips between visits
  • Keep the extract on whenever the range is in use
  • Keep every filter in place during service

Your team carries on as normal, without the filter washing. Just keep the canopy clear for the next visit and let us know of any changes to opening hours.

Damaged filters leave gaps in the defence. Replacing them early protects the plenum and ductwork.

What staff can safely do

Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That’s our job.

Staff cleaning and specialist work aren’t the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.

What happens on the day

We’re used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. On site, the work takes well under an hour for most canopies. Pictures of the system and its access let us plan the work in Wouldham before we set off.

  1. We count and measure the filters in every canopy.
  2. We agree a schedule that suits how much the kitchen cooks.
  3. At each visit, the greasy filters are lifted out.
  4. We fit clean filters and check they sit snugly in the housing.
  5. If a filter is damaged or the plenum needs attention, we tell you.

Before we arrive

  • Move anything stored near the system
  • Arrange a key holder or contact on site
  • Tell us the best time to work, such as after service or at a weekend

Getting a quote

Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.

Advice

For landlords and multi-site operators

Records are where multi-site compliance often slips. Each visit ends with a dated report and pictures, so you can show an insurer or inspector what was done at each site.

Facilities teams in offices, schools and healthcare sites book us too in Wouldham and across Medway. Larger estates can be phased building by building to keep disruption down.
