Brewer Street questions

Can school kitchens in Brewer Street be cleaned in the holidays?

Yes, and it’s the easiest time to do it. The FSA’s register shows about 4 schools and colleges with food registrations within roughly a mile and a half of Brewer Street. You can call 0345 646 2711 or use the quote form with the dates the site is empty.

Who inspects food businesses in Brewer Street?

That’s Tandridge council, whose environmental health officers carry out food hygiene inspections in Brewer Street. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.

Which kinds of sites do you work on?

All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. We fit the work around how the site operates.

Where do the greasy filters go?

We take them away to be cleaned, so your staff don’t have to wash them. Clean filters go straight in.

Do you recommend a next date?

Yes. The recommended date is on the report. BESA’s minimum intervals for kitchen extracts range from 3-monthly for heavy use to 12-monthly for light use, and fire dampers need testing at least once a year.

What types of filter do you exchange?

Both baffle filters and mesh filters are covered. We record the sizes and number of filters at the start so the clean set always fits.

Do you cover Brewer Street?

Yes. We cover Brewer Street and across Surrey, within our South East and London area. To book, call 0345 646 2711 or send us an email.

Will I get paperwork for my records?

Yes, on every job. It’s a dated, written report with photos, plus a certificate via the BESCA Vent Hygiene Elite portal for TR19® Grease cleans. Keep it in your maintenance log.

Grease filter exchange for kitchens and businesses in Brewer Street

A filter that does not sit right lets grease straight past. Gaps in the filter bank are a direct route into the plenum and every filter is checked when we swap them. We point out any that need replacing. We’re often asked to deal with blocked baffle filters and hand-washed filters that still look greasy, across baffle filters, wall canopies and restaurants and pubs.

In a small place like Brewer Street, kitchens are often in older or extended buildings, with long single-storey duct runs, and those horizontal sections are where grease settles. We agree access and timings in advance.

Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

The process

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 the area around the work is covered and protected. On site, it takes a short visit, depending on how many filters the canopies hold. The timing of a visit to Brewer Street is set by you, and the travel is our side of the planning.

  1. We start by noting how many filters you have and what type they are.
  2. Together we set how often the filters should be changed.
  3. On each visit, the dirty filters come out of the canopy.
  4. Clean filters go straight back in, seated properly with no gaps.
  5. We flag any damaged filters or anything wrong with the canopy.

Before we arrive

  • Let us know when the site is closed or quiet
  • Arrange a key holder or contact on site
  • Tell us where we can park and unload

Aftercare tips

A little care between visits keeps the system in better shape. We recommend:

  • Never leave gaps in the filter bank
  • Report damaged filters so they can be replaced
  • Never cook with the extract switched off
  • Tell us if the menu or opening hours change

Keep an eye out for filters that have been taken out. Gaps let grease into the plenum, so let us know if one goes missing or gets damaged.

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

Different parts, different methods

The plenum

Behind the filters sits the plenum, where air gathers before the duct. It collects whatever grease the filters miss.

School, care home and staff kitchens

A longer exchange interval may suit lighter cooking. The interval is set to fit.

Grease filter exchange around Brewer Street

The FSA’s food hygiene register includes about 3 pubs and bars within about 1.5 miles of central Brewer Street. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Fire safety in Brewer Street falls to Surrey Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. It’s Tandridge council that sends environmental health officers to food businesses in Brewer Street. Extraction counts as kitchen equipment, so its condition can come up on the day. Our report lists what was cleaned and when, which is useful to have ready.

Term dates shape school work: for a school like Bletchingley Village Primary School, an extract clean fits neatly into a half-term or summer break. Where a hall near Church of St Mary the Virgin, or anywhere in Brewer Street, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

Leave it or put it right?

Washing filters in-house is an option for kitchens in Brewer Street, and that can work if it’s done thoroughly and on time. Where it slips, an exchange service takes the job off staff. A planned visit to Brewer Street is easier to arrange than an emergency callout.

What you pay depends on the size of the system, what state it’s in and how easy it is to reach. We give you a fixed price before any work starts, so there are no surprises.

Why us?

  • We diagnose before we treat
  • Fully insured
  • Fixed quotes from a survey or pictures
  • Ventilation hygiene specialists since 2009

When to call us in Brewer Street

Washing filters by hand does not always get them clean. Grease hides in the folds of a baffle or the layers of a mesh, and a quick rinse leaves it there.

It’s time to book a visit if you see:

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

Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Caterham Dene Hospital is the nearest hospital to Brewer Street, about 2.2 miles north.

Our hiring checklist

What staff can safely do

Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.

When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We will take a look and give you a fixed quote.

What affects the cost of grease filter exchange

You will get a fixed price before we start. It takes into account:

  • Working hours and out-of-hours timing
  • Travel, parking and unloading
  • How many systems or sites are involved
  • A single visit or a regular plan

You won’t find a price list here, because the cost depends on the site in front of us. For a fixed quote, call us on 0345 646 2711 or email us, and we’ll explain what it covers.

Helping us quote

Before you ask for a quote, gather:

  • Close-ups of filters, grilles, hatches or access panels
  • Any previous report or certificate
  • Where the plant sits or the system leaves the building, such as a roof or outside wall
  • The postcode and the type of business

Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before work begins.
