Grease filter exchange near Green Cross

Grease filter exchange for kitchens and businesses in Green Cross

Think of filter exchange as routine care for the extract. It keeps airflow up and grease down between full cleans and takes a messy task off your team. The full TR19 clean then gives the system its clean bill of health. If you have smoke and heat lingering under the hood and grease left in baffles after washing, we can put it right.

Somewhere as small as Green Cross, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Each still has a canopy and duct that collect grease.

For insurers and inspectors, the record counts. That’s why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Between visits

Once we’ve finished, these simple steps help:

  • Tell us if the menu or opening hours change
  • Tell us if a filter is bent or damaged
  • Never cook with the extract switched off
  • Don’t let the full clean slip because filters are changed

We tell you if we spot anything in the canopy that needs attention. It can be a sign that a full TR19® clean is due, and we can arrange it.

Damaged filters leave gaps in the defence. Sorting them now keeps grease where it can be caught.

What your team can do, and what needs us

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

A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.

Common problems we fix in Green Cross

Kitchens in Green Cross, as everywhere, find filter washing slips down the list on busy weeks. It only takes a couple of missed weeks for a filter bank to clog.

These are the problems we see most often:

  • Filter washing that keeps being missed
  • A greasy plenum behind the filters
  • Bent or damaged filters that do not sit properly
  • Blocked baffle filters

Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Haslemere and District Hospital is the nearest hospital to Green Cross, about 3.8 miles south-east.

What we do, step by step

There are three stages on the day: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, while signing off means the written report and pictures. The middle part takes longest, and that takes anything from a few minutes to an hour or so, depending on the number of filters. If you can send photos, we can arrive in Green Cross knowing what to expect.

  1. We record the number, size and type of your filters.
  2. We set the interval with you.
  3. On each visit, we remove the greasy filters.
  4. Clean filters go in and we check they sit snugly.
  5. The dirty filters leave with us and the next visit is booked.

Getting ready for the visit

  • Let us know about permits to work or site inductions
  • Mention any parking or loading restrictions
  • Have your last certificate or report to hand

Green Cross kitchens: local notes

Food Standards Agency records list about 5 cafés, restaurants and staff canteens within about 1.5 miles of central Green Cross. Each canopy among them has filters that load with grease and need swapping or cleaning. Surrey Fire and Rescue Service covers Green Cross. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises. In Green Cross, food businesses are inspected by environmental health officers from Waverley council. Extraction counts as kitchen equipment, so its condition can come up on the day. Keeping each certificate and photo report on file helps show the extract is looked after.

For schools such as St John's CofE Aided Infant School, kitchen extract cleaning is normally booked for the holidays, when the canteen is closed. If you run a church or community hall kitchen, near St John the Evangelist or elsewhere in Green Cross, its extract still collects grease from every lunch and event.

Leave it or put it right?

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. Out of sight is the usual reason a rural system goes too long without attention.

The cost depends on how big the system is, what state it’s in and how easy it is to reach. We give you a fixed price before work begins, so you know where you stand.

Why book with us

  • Every visit written up, with pictures
  • CHAS and SafeContractor accredited, with ISO 9001
  • We’re fully insured
  • A BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease

Fixed quotes for grease filter exchange in Green Cross

Some jobs are bigger than they look, and some smaller. The main factors:

  • What state the system is in
  • Site rules, permits and inductions
  • How many systems or sites are involved
  • How easy every part is to reach

The price reflects the work, not guesswork. That is why we survey first, from pictures or on site, and the price is agreed before we start.

What we need to know

Many jobs can be priced from photos and some basics. Useful things to send:

  • How we’d reach plant on a roof or in a plant room
  • Where the site is and what kind of site it is
  • Any access panels or hatches you can see
  • 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. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.

Common questions in Green Cross

Who is the fire and rescue service for Green Cross?

Fire safety enforcement in Green Cross is handled by Surrey Fire and Rescue Service. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.

Can you come to Green Cross after we close?

Yes, out-of-hours work is a big part of what we do. It means the site in Green Cross keeps running as normal. Just ring 0345 646 2711 or drop us a line with your opening times and we will plan around them.

Which grease filters does the service cover?

The common types of grease filter: baffle and mesh. Tell us what you have when you give us a ring on 0345 646 2711 or email us and we’ll confirm it on site.

Which kinds of sites do you work on?

Any site with a kitchen or a ventilation system to look after, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.

Do you work in Green Cross?

Yes. We work across Greater London, Surrey, Kent, Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, and that includes Green Cross.

Will you tell us when the next visit is due?

Yes. The recommended date is on the report. For kitchen extracts, BESA’s minimum intervals run from every 3 months for heavy use to every 12 months for light use, while fire dampers are tested at least annually.

Do you deal with bent or broken filters?

We check every filter at each visit. We tell you about any that are damaged, because gaps let grease into the plenum.

Can one contract cover all our sites?

Yes. Tell us the addresses and what each needs and you will get one fixed quote.

What a clean won’t put right

Not every problem is solved by grease filter exchange, and we’d rather say so up front. It won’t put right:

  • A heavily greased plenum or canopy, which needs cleaning to TR19
  • Grease deep in the extract system
  • Smell complaints that need odour control equipment

Not sure which it is? You can call us on 0345 646 2711, or send details by email and we will tell you honestly.
