Grease filter exchange in Brentwood

What grease filter exchange looks like in Brentwood

There are about 80 cafés, restaurants and staff canteens and about 32 takeaways and sandwich shops in Brentwood and the streets around it, up to about 1.5 miles out, according to the Food Standards Agency’s register. Where they cook under a canopy, the grease filters are the first line of defence and clog quickly. Brentwood sits within the area of 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. Environmental health officers from Brentwood council inspect food businesses in Brentwood. 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.

School kitchens, at schools like Becket Keys Church of England School for example, are usually cleaned in the holidays so no lunches are lost. Where a hall near Church of St Thomas of Canterbury, or anywhere in Brentwood, hosts lunch clubs or events, its extract gathers grease just as a café’s does. If you run catering at a healthcare site, such as a hospital like Brentwood Community Hospital about 0.5 miles east, the extract may need cleaning more often than a part-time kitchen.

How we handle grease filter exchange in Brentwood

A filter service works alongside TR19® cleaning, not instead of it. Fresh filters help limit what gets into the ductwork though vapour still carries some grease past them. So the canopy, plenum and ducts still need their full TR19 clean. The work covers mesh filters, restaurants and pubs and island canopies, and the jobs we see most are damaged filters letting grease past and filters left unwashed on busy weeks.

Many kitchens in a town like Brentwood were fitted into buildings built for something else, so duct runs can be awkward, with bends, long horizontal sections and too few access panels. Where the duct cannot be reached, new panels can be fitted, and anything left uncleaned is recorded on the report.

The paperwork matters as much as the work. You get a written report with pictures after each visit, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

What happens if it’s left?

Changing filters on schedule costs far less disruption than a blocked extract. Few maintenance jobs are as easy, and one of the easiest to let slip. If an inspection, an insurer’s survey or a fire risk assessment is coming up in Brentwood, having the work done and recorded first helps.

What you pay depends on how big the system is, the condition it’s in and how easy it is to reach. You get a fixed price before work begins, so you know where you stand.

Brentwood questions

Can you clean school kitchen extracts in Brentwood during the holidays?

Yes, out-of-term visits are normal for schools. The FSA’s register shows about 12 schools and colleges with food registrations within roughly a mile and a half of Brentwood. Just call 0345 646 2711, or email photos with your term dates and we’ll plan around them.

Who enforces fire safety at workplaces in Brentwood?

Essex County Fire and Rescue Service is the fire and rescue service for Brentwood. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.

Can you look after several sites?

Yes. Tell us the addresses and what each needs and we will quote them together.

What is TR19?

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

What accreditations do you have?

We hold CHAS, SafeContractor and ISO 9001, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.

Do you cover Brentwood?

Yes. We work across Greater London, Surrey, Kent, Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, Brentwood included.

Do you deal with bent or broken filters?

A bent filter leaves a gap for grease. We point them out on the visit so they can be replaced.

How do you protect the area?

Protection goes down first: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.

Part by part

Canopy filter housings

Grease collects in the channels and drip trays below the filters. We point it out if it needs cleaning.

Mesh filters

Mesh traps grease between its layers, so a quick rinse rarely gets it clean.

What a clean will not put right

A few issues sit outside what this work can do:

  • A canopy that doesn’t capture the vapour properly
  • A heavily greased plenum or canopy, which needs cleaning to TR19
  • A noisy or failed extract fan

Not sure which it is? You can give us a ring on 0345 646 2711 or use the quote form and we will tell you honestly.

What we work on in Brentwood

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

Between visits

Aftercare is simple, and it helps at the next visit:

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

Fresh filters improve airflow at the canopy from the moment they’re fitted. Always run the extract during cooking so they catch grease as intended.

Dripping filters are a clear sign they’re full. Changing them now reduces the fuel above the cooking, and it’s worth checking the plenum too.

The process

We start by comparing what we find with the survey or your photos. If anything is different, we talk it through with the person on site before carrying on. From there, it takes less than an hour in most kitchens. Sites in a town like Brentwood rarely need to lose trading hours, as the work fits around them.

  1. We record the number, size and type of your filters.
  2. An exchange schedule is agreed to suit your cooking.
  3. The dirty set is lifted out.
  4. Clean filters go in and we check they sit snugly.
  5. The dirty filters leave with us and the next visit is booked.

Preparing for the visit

  • Agree a time when the area can be out of use
  • Let us know how we reach the system, including roofs, risers and plant rooms
  • Find the previous report, if there is one

Advice

Multi-site and managed buildings

For anyone managing more than one site, we can plan visits across the whole estate and price them together. Every building has its own written report, so each one has its own record.

Managing agents often deal with us directly. Tell us the site, the work and the access arrangements and we will come back with a fixed quote.

In-house cleaning or a specialist?

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.

Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
