Grease filter exchange for sites in Nash

Grease filter exchange for kitchens and businesses in Nash

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. Regular exchange keeps the air moving. The work covers baffle filters, island canopies and restaurants and pubs, and common reasons people get in touch are filter washing that keeps being missed and smoke and heat lingering under the hood.

London kitchens tend to trade late and open early, so extract cleaning in Nash is usually done overnight, after the last service. Before the clean, we agree loading, parking and roof access with whoever manages the building.

We’ve been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.

Managing agents and facilities teams in Nash

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

If you look after several sites, we can schedule visits across all of them on one quote. Every building has its own written report, so each one has its own record.

How it works

At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and the same goes into the written report. All told, the work takes a few minutes per canopy, longer for a large kitchen with several canopies. Night and weekend working is normal for us in London, and a site in Nash is no exception.

  1. We look at the canopies and the condition of the filters.
  2. Any damaged or missing filters are noted.
  3. Greasy filters are swapped for clean ones.
  4. The filters are checked for fit before we go.
  5. We tell you if the plenum or canopy needs a clean.

Preparing for the visit

  • Clear the space around the work
  • Find the previous report, if there is one
  • Arrange a key holder or contact on site

Nash: your questions answered

Can you come to Nash after we close?

Yes, we can come after you close and finish before you open. The work in Nash can fit around your hours. When you call 0345 646 2711, or email photos, mention when the site is quiet.

Can parking be tricky for a job in Nash?

We plan it in advance, so let us know about loading bays, permits and access rules at the building. Working overnight, as we often do in London, typically makes it simpler.

Will I get paperwork for my records?

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

How much notice should we give?

It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and if it’s an emergency, call us any time.

How often should grease filters be changed?

It depends on how much and what the kitchen cooks. Kitchens that fry and grill all day need changes more often than kitchens that cook less. We agree the interval with you.

Is Nash in your area?

Yes. We cover Nash and the rest of Greater London, within our South East and London area. To book, call us on 0345 646 2711 or send us an email.

Is there a survey before the work?

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.

Which accreditations do you hold?

We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

Grease filter exchange in Nash: the local picture

The Food Standards Agency lists about 9 bars, pubs and nightclubs as registered food businesses within about 1.5 miles of central Nash. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. In London, kitchens are normally cleaned overnight, when the kitchen is closed and loading is easier. Fire safety in Nash falls to London Fire Brigade. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract.

School kitchens, at schools like Wickham Common Primary School for example, are normally cleaned in the holidays so no lunches are lost. If your kitchen is in a listed or historic building, like the houses around Nash (Down House is about 2.4 miles south-east), fitting access panels needs care.

Nash is about 3 miles south of Bromley, in Greater London. For grease filter exchange in and around Nash, please ring 0345 646 2711 or email us for a fixed quote.

When something else is needed

A few issues sit outside what this work can do:

  • A canopy that needs a proper clean
  • Grease already built up in the ductwork, which needs a full TR19 clean
  • Cooking smells reaching neighbours, which need odour control

If you’re not sure, just phone us on 0345 646 2711, or email photos and we’ll give you a straight answer.

Parts of the system we cover

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

How the job changes from site to site

The plenum

With good filters, less grease ends up in the plenum, but it’s still cleaned during a full TR19 clean.

Baffle filters

When baffles fill with grease, less air gets through. A clean exchange set brings the airflow back.

Fixed quotes for grease filter exchange in Nash

The quote reflects the site in front of us. We take into account:

  • One-off work versus a regular cycle
  • Access, including roofs, risers and ceiling voids
  • Whether several sites go on one quote
  • Site requirements such as sign-in and permits

Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll go through it with you.

What we need to know

Before you ask for a quote, gather:

  • A few general shots of the system
  • The roof, plant room or outside wall the system runs to
  • Any symptoms, from odd noises to smells or leaks
  • The paperwork from the last visit, if you have it

The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.

What we are called out for in Nash

Hand-washed filters often come back still greasy. Grease lodges deep in baffles and mesh, and a quick rinse leaves it there.

Keep an eye out for any of the following:

  • Filters that come out of the sink still dirty
  • Smoke and heat lingering under the hood
  • A greasy plenum behind the filters
  • Missing filters in the filter bank

Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Princess Royal University Hospital is the nearest hospital to Nash, about 1.8 miles east.

Comparing quotes

  • Whether inaccessible sections are listed on the report
  • What paperwork you get at the end
  • Whether the quote shows VAT
  • Proof of insurance

Questions to ask before booking

Looking after it afterwards

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

  • Clean the canopy surfaces regularly
  • Report a dripping canopy early
  • Never leave gaps in the filter bank
  • Report damaged filters so they can be replaced

Fresh filters improve airflow at the canopy from the moment they’re fitted. Keep the extract running while you cook so the filters do their job.

A kitchen that’s getting busier needs its filters changed more often. Changing the interval early stops grease building up unseen behind the canopy.
