Grease filter exchange near Southfields

Grease filter exchange in Southfields, done properly

Baffle filters and mesh filters both fill with grease. Once they’re clogged, airflow drops and the extract struggles. A steady cycle of clean filters keeps extraction strong. The work covers island canopies, restaurants and pubs and school and hospital kitchens, and common reasons people get in touch are grease building up behind the canopy filters and missing filters in the filter bank.

London kitchens are often tucked into basements or the back of a building, with extract ducts that can climb several floors to discharge at roof level. In Southfields, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.

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.

Landlords, agents and facilities managers

Facilities teams in offices, schools and healthcare sites book us too in Southfields and across Greater London. Larger estates can be phased building by building around the people who use them.

We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we’re happy to quote for all of it.

What affects the cost of grease filter exchange

The price is fixed before any work begins. It’s based on:

  • The size of the system
  • One-off work versus a regular cycle
  • Site requirements such as sign-in and permits
  • Whether we need access equipment or extra panels

A single site or a whole portfolio, the quote is built the same way: what needs doing, how we get to it and when. You’ll have a fixed price before we start.

What to send for a quote

To help us quote quickly, please include:

  • A few general shots of the system
  • Where the plant sits or the system leaves the building, such as a roof or outside wall
  • The paperwork from the last visit, if you have it
  • Anything you’ve noticed, such as smells, noise, drips or poor airflow

Every quote begins with a look at the system, either from pictures and details you send or from a site visit. Then we send a fixed price, before any work starts.

Aftercare tips

Once we have finished, these simple steps help:

  • Don’t let the full clean slip because filters are changed
  • Keep canopy surfaces wiped down
  • Keep every filter in place during service
  • Make sure we can reach the canopy on exchange day

Nothing changes for your staff, except one less greasy job. Make sure we can reach the canopy on exchange day and let us know of any changes to opening hours.

If filters are already dripping, they’re overdue. A clean set right away cuts the grease in the canopy, and it’s worth checking the plenum too.

Southfields questions

Can you clean school kitchen extracts in Southfields during the holidays?

Yes. Half-terms and the summer break are the natural time for school work. Around Southfields, the Food Standards Agency lists about 21 schools and colleges with registered kitchens within a mile and a half or so. Just give us a ring on 0345 646 2711, or send details by email with your term dates and we’ll plan around them.

How do you handle parking and loading in Southfields?

Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Much of our London work is done overnight, which helps.

Do we need to close the kitchen while filters are changed?

A change takes a few minutes per canopy, longer for a large kitchen with several canopies, so disruption is small. We plan visits outside your busiest times wherever possible.

Do you look at the system first?

Yes. For many sites, photos and a few details are enough, while bigger or harder-to-see systems are surveyed on site.

Do you offer emergency callouts?

Yes, 24/7. Our office is open from 8am to 6pm on weekdays, with the emergency line covering every other hour.

Will I get paperwork for my records?

Yes. It’s your proof that the work was done: a written, dated record with pictures of what we did and anything we couldn’t access.

Do you take the used filters away?

The greasy set leaves with us for cleaning, so your staff don’t have to wash them. A clean set is fitted in their place.

How much notice should we give?

For planned work, earlier is better, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.

What the work involves, part by part

Busy restaurant and pub kitchens

In a busy kitchen, filter washing is easy to skip. An exchange service takes it off the rota.

Mesh filters

Mesh traps grease between its layers, which makes hand-washing hard work.

Do you need grease filter exchange in Southfields?

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 sink wash rarely reaches it.

What we are most often called out for:

  • A canopy running with filters missing
  • Poor airflow through the filters
  • Staff short of time to wash filters
  • A canopy that drips grease

If you run a church or community hall kitchen, near St John the Divine or elsewhere in Southfields, its extract still collects grease from every lunch and event.

What your quote should include

  • How VAT is shown on the quote
  • Whether the price is fixed
  • Whether the whole system is included, or only the parts that are easy to reach
  • Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor

How to choose an extract cleaning contractor

What grease filter exchange looks like in Southfields

The FSA’s food hygiene register shows about 373 restaurants, cafés and works canteens and about 69 takeaways and sandwich shops in and around Southfields, up to about a mile and a half out. Swapping filters on a schedule keeps kitchens like these drawing air properly. London jobs normally start after the last service, with loading and roof access agreed with the building first. It’s Wandsworth council that sends environmental health officers to food businesses in Southfields. 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 Floreat Wandsworth Primary School, an extract clean fits neatly into a half-term or summer break. Healthcare kitchens, like those at hospitals such as Royal Hospital for Neuro-disability (about 1 mile west), often cook for long hours, which puts them in BESA’s heavier-use bands.

How it works

Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. On site, the work takes anything from a few minutes to an hour or so, depending on the number of filters. For a job in Southfields, tell us about loading bays, permits, lifts and roof access when you book.

  1. We record the number, size and type of your filters.
  2. We set the interval with you.
  3. The dirty set is lifted out.
  4. A clean set is fitted and checked for gaps.
  5. The dirty filters leave with us and the next visit is booked.

Preparing for the visit

  • Tell us the best time to work, such as after service or at a weekend
  • Allow time for equipment near the work to be turned off and cool down
  • Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas

Getting a quote

Getting a quote doesn’t take long. Send a few details and pictures, and we normally reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
