Grease filter exchange for sites in Cobham

How it works

Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. On site, the work takes well under an hour for most canopies. Tell us when your site near Cobham is quiet and the visit will be booked for then.

  1. First, we check the canopies and the filters in them.
  2. Any damaged or missing filters are noted.
  3. We exchange the dirty filters for a clean set.
  4. We check the filters are seated and the canopy is ready to use.
  5. We tell you if the plenum or canopy needs a clean.

Preparing for the visit

  • Agree a time when the area can be out of use
  • Let us know about parking and loading
  • Plan for cooking equipment or plant to be off before we arrive

Get a fixed quote

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

Advice

Grease filter exchange in Cobham, done properly

In Cobham, our filter exchange runs on a schedule set by how much the kitchen cooks. The heavier the cooking, the more often filters need changing while a lighter kitchen can go longer. The interval is agreed before the first visit. The work covers restaurants and pubs, baffle filters and wall canopies, and common reasons people get in touch are a canopy running with filters missing and filters that come out of the sink still dirty.

In a smaller place like Cobham, many kitchens sit in older buildings or later extensions, with the duct running through a roof space or up an outside wall. Long horizontal runs like that hold grease and need access panels to reach.

We have 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 carry full insurance.

Cobham: your questions answered

Do you work in villages like Cobham?

Yes, Cobham is part of our area, however small the site. Let us know about access, parking and anything unusual about getting there when you book.

Who inspects food businesses in Cobham?

Kitchens in Cobham are inspected by Elmbridge council’s environmental health officers. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.

Will I get paperwork for my records?

Yes. Each visit ends with a written report and pictures, showing what was done, anything we couldn’t reach and when the next visit is due. Where the work is a TR19® Grease clean, there’s also a certificate issued through the BESCA Vent Hygiene Elite portal.

How do you protect the area?

With sheeting and covers, before anything else happens. The work is kept contained and clean down when we finish.

What’s TR19?

It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping and expects a risk-based approach.

Can you give a price for filter changes?

The cost depends on your filters and the schedule. Just give us a ring on 0345 646 2711 or drop us a line for a fixed quote, normally within one working day.

Where does the waste go?

It’s contained and taken away. Grease, debris and waste water are collected as the work goes on, so it does not spread.

How much notice do you need?

Earlier is better, particularly for night and weekend visits. Quotes usually come back within one working day, and emergencies are covered by our 24/7 line.

Kitchen extracts in Cobham

The FSA’s food hygiene register shows about 21 restaurants, cafés and canteens and about 6 sandwich bars and takeaways in Cobham and the streets around it, up to about 1.5 miles out. Swapping filters on a schedule keeps kitchens like these drawing air properly. Fire safety in Cobham falls to Surrey 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. Kitchens in Cobham get their food hygiene inspections from Elmbridge council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A TR19® certificate and photo report after each clean gives you a record to show an inspector.

Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; No. 2 New Zealand General Hospital is the nearest hospital to Cobham, about 3.9 miles north. Church and community hall kitchens, near Church of St Andrew or anywhere around Cobham, are easy to forget, but their extracts collect grease like any other. Term dates shape school work: for a school like St Andrew's CofE Primary School, an extract clean fits neatly into a half-term or summer break.

Aftercare tips

Once we have finished, these simple steps help:

  • Mention it if the kitchen gets busier
  • Report a dripping canopy early
  • Keep the canopy clear for exchange visits
  • Wipe the outside of the canopy as part of daily cleaning

Between visits, check that every filter is still in place. Gaps let grease into the plenum so tell us if you need a replacement.

Bent or missing filters let grease straight past. Sorting them now keeps grease where it can be caught.

Why deal with it now?

Once filters are saturated, more grease gets past them. The ductwork then loads up faster, and grease may build up faster than the cleaning interval allows. It’s easy to lose track of when the work was last done on a quieter site.

Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll go through it with you.

  • A single point of contact for sites across the South East and London

How the job changes from site to site

Baffle filters

Baffle filters use overlapping metal blades that force the air to change direction. Grease is thrown out of the airstream and collects on the baffles.

The plenum

The plenum is the space behind the filters. Grease that gets past the filters settles there.

Staff cleaning versus specialist work

When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We will take a look and give you a fixed quote.

Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.

How we price grease filter exchange

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

  • Whether several sites go on one quote
  • Working hours and out-of-hours timing
  • Where the site is and how we reach it
  • How big the system is

No two sites are the same, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all make a difference.

What to send for a quote

A few details help us quote accurately. When you get in touch, it helps to send:

  • Problems your staff have spotted
  • The times we could work without disrupting the site
  • Any previous report or certificate
  • Where the site is and what kind of site it is

We don’t publish a price list, because every site is different. We look at your system first, from pictures or on a visit, then send a fixed quote. To start, call 0345 646 2711, or email photos.

Multi-site and managed buildings

We regularly work with managing agents. Send the address, what’s needed and how access works and we will come back with a fixed quote.

Facilities teams in offices, schools and healthcare sites book us too across Surrey. Work can be phased by floor, building or site around the people who use them.
