Grease filter exchange in Thorrington, Essex

Grease filter exchange for commercial sites in Thorrington and across Essex. BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease.

  • Drips falling from the filters onto equipment
  • Grease building up behind the canopy filters
  • Hand-washed filters that still look greasy

Grease filter exchange across Thorrington

Different parts, different methods

School, care home and staff kitchens

Visits can be planned around holidays and quieter periods so the filters are clean when cooking picks up.

Baffle filters

Baffle filters are a common choice for commercial canopies. They do not clean themselves, because the grease they collect builds up.

Grease filter exchange for kitchens and businesses in Thorrington

Good filters only work when they fit properly. Gaps in the filter bank are a direct route into the plenum, so we check every one at each visit. We point out any that need replacing. The work covers school and hospital kitchens, baffle filters and wall canopies, and the jobs we see most are grease filters clogged with grease and a canopy running with filters missing.

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

A written report with photos follows each visit, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

What happens if it’s left?

A filter exchange is a few minutes; a choked extract affects a whole service. It’s one of the simplest parts of looking after the system, and one of the easiest to let slip. It’s simpler to plan the work at Thorrington now than to arrange it in a hurry later.

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 there are no surprises.

Your questions about grease filter exchange in Thorrington

Which fire authority looks after Thorrington?

It’s Essex County Fire and Rescue Service, which covers Thorrington. TR19® isn’t law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.

Can school kitchens in Thorrington be cleaned in the holidays?

Yes, holiday work suits schools best. Around Thorrington, the Food Standards Agency lists about 3 schools and colleges with registered kitchens within a mile and a half or so. Just phone us on 0345 646 2711 or send us an email with your term dates and we will plan around them.

Is filter exchange enough instead of a full extract clean?

No. Some grease passes the filters as vapour and settles in the ducts and the whole system still needs its TR19 clean.

What paperwork should we keep on file?

Each report and certificate we give you, filed in the maintenance log, along with your own cleaning log. BESA advises that certificates record the date, location and technician.

How regularly do grease filters need exchanging?

It varies with the type and amount of cooking. If filters are dripping or clogging before the next change, it’s too long and we’ll adjust it.

Do you survey before quoting?

Yes, every time. We diagnose before we treat: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.

Do you clean filters as well as exchanging them?

Yes, filters can be cleaned on a schedule as well as exchanged. We will talk you through which suits your kitchen when you get in touch.

How do you protect the area?

With sheeting and covers, before anything else happens. We keep the work contained and leave the area clean.

Kitchen extracts in Thorrington

Thorrington lies within about 3 miles of the sea. Salt air speeds up corrosion of roof-level fans, discharge cowls and their fixings. The FSA’s food hygiene register shows about 5 cafés, restaurants and staff canteens and about 4 sandwich bars and takeaways within roughly a mile and a half of the centre of Thorrington. Each canopy among them has filters that load with grease and need swapping or cleaning. The fire and rescue service for Thorrington is Essex County Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.

Term dates shape school work: for a school like Colne Community School and College, an extract clean fits neatly into a half-term or summer break. Church and community hall kitchens, near Church of St Mary Magdelene or anywhere around Thorrington, are easy to forget, but their extracts collect grease like any other.

Between visits

Aftercare is simple, and it makes the next visit easier:

  • Keep filter exchange and TR19 cleaning on the same plan
  • Wipe the outside of the canopy as part of daily cleaning
  • Keep the extract on whenever the range is in use
  • Keep the canopy clear for exchange visits

Between visits, check that every filter is still in place. Gaps let grease into the plenum, so let us know if one goes missing or gets damaged.

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

When it’s something else

Not every problem is solved by grease filter exchange, and we’ll tell you before we start. It does not solve:

  • Smell complaints that need odour control equipment
  • Grease behind the filters that a swap can’t remove
  • Extraction problems caused by the fan rather than the filters

If you’re not sure, just phone us on 0345 646 2711, or send details by email and we will give you a straight answer before booking.

What the work covers

  • Island canopies
  • Restaurants and pubs
  • Baffle filters
  • School and hospital kitchens
  • Wall canopies
  • Mesh filters

How it works

Protection comes first: floors, worktops and anything near the work are covered. Then we make the system safe and start. It takes a short visit, depending on how many filters the canopies hold, and the area is cleaned down before we leave. If you can send pictures, we can arrive in Thorrington knowing what to expect.

  1. We look at the canopies and the condition of the filters.
  2. We note any filters that are bent, damaged or missing.
  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 where we can park and unload
  • Allow time for equipment near the work to be turned off and cool down
  • Make sure someone can let us in and lock up afterwards

Ask for a quote

Quotes are quick. Call or email with a few details and you’ll usually have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.

In-house cleaning or a specialist?

Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.

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. That’s our job.

How we price grease filter exchange

We do not publish a price list, because no two systems are the same. What we look at:

  • One-off work versus a regular cycle
  • Site rules, permits and inductions
  • How easy every part is to reach
  • Travel, parking and unloading

The price reflects the work, not guesswork. That’s why every job is surveyed first, and the price is agreed before we start.

Asking for a quote

Photos let us diagnose from a distance. Try to include:

  • Detail shots of panels, filters and grilles
  • The roof, plant room or outside wall the system runs to
  • Any previous report or certificate
  • The times we could work without disrupting the site

Every quote begins with a look at the system, either from photos and details you send or from a site visit. Then we send a fixed price so you know the cost before any work starts.
