Grease filter exchange near Hersham

What the work involves, part by part

The plenum

Behind the filters sits the plenum, where air gathers before the duct. Grease that gets past the filters settles there.

Canopy filter housings

Grease collects in the channels and drip trays below the filters. If it needs attention, we’ll tell you.

Grease filter exchange in Hersham, done properly

In Hersham, our filter exchange runs on a schedule set by how much the kitchen cooks. Busy kitchens need changes more often, lighter ones less. The interval is agreed before the first visit. Common call-outs are for filters left unwashed on busy weeks and poor airflow through the filters, across mesh filters, wall canopies and baffle filters.

In a smaller place like Hersham, the kitchens with extract systems are more likely to be a pub, a café, a takeaway or a school or care home kitchen than a big restaurant. Quieter kitchens still collect grease in the duct, just more slowly, so cleaning is planned around how much it cooks and what the readings show.

The sign-off is always in writing: a written report, dated and illustrated with photos, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

Hersham questions

Do you do school kitchen extract cleaning in Hersham in the summer holidays?

Yes, out-of-term visits are normal for schools. With about 7 schools and colleges on the FSA’s register within roughly a mile and a half of Hersham, it pays to plan holiday dates ahead. Booking early in the term gives the best choice of holiday dates.

Who carries out food hygiene inspections in Hersham?

The local authority for Hersham is Elmbridge council, and its environmental health team does the inspecting. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.

How do you keep the site clean during the work?

We cover floors and nearby surfaces with sheeting before any work starts, and anything we remove is contained. Before we leave, we tidy up and clean down.

Which records should we keep?

Each report and certificate we give you, kept together in your maintenance log, along with your own cleaning log. BESA says certificates should show the date, location and technician.

Which accreditations do you hold?

BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We’re fully insured and have been trading since 2009.

How long does the visit take?

The work itself takes a short visit, depending on how many filters the canopies hold. Bigger or more complicated systems take longer, and we’ll tell you what to expect.

What types of premises do you cover?

Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.

Can you look after several sites?

Yes. Our area covers London and the South East, so we can schedule a run of sites on one programme. Each site gets its own report and pictures.

When it’s something else

In fairness, there are a few things this work will not fix:

  • A noisy or failed extract fan
  • Grease behind the filters that a swap cannot remove
  • Odours from the discharge that filters will not stop

If you are not sure, just ring 0345 646 2711 or email us and we will give you a straight answer.

Where we work

  • Restaurants and pubs
  • Wall canopies

What affects the cost of grease filter exchange

Your quote is based on your site. We consider:

  • Working hours and out-of-hours timing
  • Whether it’s a one-off visit or part of a schedule
  • The size of the system
  • Site requirements such as sign-in and permits

Combining work into one visit or one programme often makes better use of the time. Mention every system or site you need covered, and you’ll get one fixed quote.

Helping us quote

Photos and a few facts are often enough to price the work. Send what you can of the following:

  • A few general shots of the system
  • Detail shots of panels, filters and grilles
  • The site address and the type of premises
  • Any previous report or certificate

Quotes are quick. Send a few details and pictures, and we typically reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.

Do you need grease filter exchange in Hersham?

Every fry, grill and sauté sends grease-laden vapour upwards. Much of it is trapped by the filters, and day by day they load up until the air can barely get through.

The symptoms we are asked about most are:

  • Grease dripping from the canopy
  • Filters left unwashed on busy weeks
  • A greasy plenum behind the filters
  • Hand-washed filters that still look greasy

If you run a café or takeaway near Walton-On-Thames station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits.

What to look for in a quote

  • Whether the quote is based on a survey or pictures
  • Whether the work can be done while the site is closed
  • How areas they cannot reach will be recorded
  • What insurance they carry

Choosing a duct cleaning contractor

In-house cleaning or a specialist?

Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.

In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.

What happens if it’s left?

Grease dripping from the canopy is a sign the filters can’t hold any more. Left, it ends up on equipment, food areas and staff, which an EHO may well notice. Even a site near Hersham that is only busy part of the week needs its system checked on a schedule.

When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account, and the price is fixed before we start.

Why book with us

  • Fully insured
  • Ventilation hygiene specialists since 2009
  • We diagnose before we treat
  • Accredited under CHAS and SafeContractor, with ISO 9001

How it works

We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes a short visit, depending on how many filters the canopies hold. Getting to the system matters more than parking in a place like Hersham, so let us know how to reach it.

  1. First, we record the size, type and number of filters in each canopy.
  2. A change schedule is agreed to match the kitchen’s cooking hours.
  3. Each visit starts with the used filters being removed.
  4. Clean, dry filters are fitted in their place, with no gaps left between them.
  5. We flag any damaged filters or anything wrong with the canopy.

How to prepare

  • Make sure someone can let us in and lock up afterwards
  • Plan for cooking equipment or plant to be off before we arrive
  • Clear loose items from the work area

Get a fixed quote

The quickest way to a quote is to send pictures: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.

Advice

Kitchen extracts in Hersham

There are about 42 restaurants, cafés and canteens and about 20 takeaways and sandwich shops in and around Hersham, up to about a mile and a half out, according to the Food Standards Agency’s register. Any of those kitchens with a canopy relies on its filters to catch grease before it reaches the duct. Fire safety in Hersham falls to Surrey Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. It’s Elmbridge council that sends environmental health officers to food businesses in Hersham. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A dated certificate in the maintenance file answers the question before it’s asked.

If you run a church or community hall kitchen, near Church of St Peter or elsewhere in Hersham, its extract still collects grease from every lunch and event. Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Hersham is No. 2 New Zealand General Hospital, about 1.6 miles north-west.
