Grease filter exchange in Monken Hadley

Grease filter exchange in Monken Hadley, done properly

A filter that does not sit right lets grease straight past. Gaps in the filter bank are a direct route into the plenum, so we check every one at each visit. We point out any that need replacing. If you have damaged filters letting grease past and poor airflow through the filters, we can put it right, from restaurants and pubs, baffle filters and wall canopies onwards.

London kitchens tend to trade late and open early, so extract cleaning in Monken Hadley is normally done overnight, after the last service. Parking, loading and access to the roof are agreed with the building before the night of the clean.

Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we are fully insured.

Fixed quotes for grease filter exchange in Monken Hadley

Some jobs are bigger than they look, and some smaller. What affects the quote:

  • A single visit or a regular plan
  • Access, including roofs, risers and ceiling voids
  • The condition of the system
  • The number of sites or systems

Combining work into one visit or one programme can make for a more efficient booking. Mention every system or site you need covered, and you will get one fixed quote.

What we need to know

To help us quote quickly, send us:

  • Detail shots of panels, filters and grilles
  • Any symptoms, from odd noises to smells or leaks
  • Wide photos of the system and the area around it
  • Your opening hours and when the area is out of use

Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.

What a clean will not put right

Some problems need a different service or another trade:

  • A noisy or failed extract fan
  • Grease already built up in the ductwork, which needs a full TR19 clean
  • A canopy that doesn’t capture the vapour properly

Not sure which it is? You can ring 0345 646 2711 or drop us a line and we’ll tell you honestly before booking.

Where we work

  • Restaurants and pubs
  • Baffle filters
  • Mesh filters

Grease filter exchange in Monken Hadley: the local picture

The Food Standards Agency lists about 22 pubs, bars and clubs as registered food businesses in Monken Hadley and the streets around it, up to about 1.5 miles out. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. Food hygiene inspections in Monken Hadley are the job of Barnet council’s environmental health team. Extraction counts as kitchen equipment, so its condition can come up on the day. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Monken Hadley is covered by London Fire Brigade. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.

Term dates shape school work: for a school like Monken Hadley CofE Primary School, an extract clean fits neatly into a half-term or summer break. If you run a church or community hall kitchen, near Parish Church of St Mary the Virgin or elsewhere in Monken Hadley, its extract still collects grease from every lunch and event.

What your team can do, and what needs us

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 don’t reach the grease that builds up further in. That part needs specialist access and equipment.

Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.

Common problems we fix in Monken Hadley

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 and airflow falls away.

Any of these means the system needs a check-up:

  • Smoke and heat lingering under the hood
  • Gaps where filters have been removed
  • A canopy that drips grease
  • Grease left in baffles after washing

If you run catering at a healthcare site, such as a hospital like Barnet General Hospital about 1 mile south-west, the extract may need cleaning more often than a part-time kitchen.

Before you book anyone

  • Whether the quote shows VAT

How to choose an extract cleaning contractor

The process

Protection comes first: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. It takes a short visit, depending on how many filters the canopies hold, and we clear up before we go. Security desks and permits-to-work are routine in London, so let us know what your building in Monken Hadley needs from us.

  1. We start by noting how many filters you have and what type they are.
  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 filters go straight back in, seated properly with no gaps.
  5. Anything we notice, such as bent filters or a dirty plenum, is pointed out.

Before we arrive

  • Agree a time when the area can be out of use
  • Name a contact who can let us in at the agreed time
  • Mention any sign-in, permit or induction we need

Get a fixed quote

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.

Questions from Monken Hadley

Is parking a problem for work in Monken Hadley?

We plan it in advance, so let us know about loading bays, permits and access rules at the building. If the building has a loading slot system, we’ll book into it.

Who carries out food hygiene inspections in Monken Hadley?

In Monken Hadley, it’s Barnet council that carries out food hygiene inspections. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.

What is TR19?

BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not legislation, but it’s the standard people check against.

What about areas you can’t get to?

They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, and we can fit those.

How often should grease filters be changed?

The right interval depends on the kitchen. If filters are dripping or clogging before the next change, it’s too long, and we can change it.

How long does the visit take?

We will confirm the time with your quote. In most cases, the work takes well under an hour for most canopies.

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.

Will you tell us when the next visit is due?

Yes. The recommended date is on the report. BESA’s minimum intervals for kitchen extracts range from 3-monthly for heavy use to 12-monthly for light use, and fire dampers need testing at least once a year.

Different parts, different methods

Canopy filter housings

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

Busy restaurant and pub kitchens

Kitchens that fry and grill all day load their filters fast. They often need the shortest exchange interval.

Looking after it afterwards

No system stays clean for ever, but care slows the build-up. Our tips:

  • Keep canopy surfaces wiped down
  • Make sure we can reach the canopy on exchange day
  • Keep filter exchange and TR19 cleaning on the same plan
  • Keep every filter in place during service

Fresh filters improve airflow at the canopy from the moment they’re fitted. Always run the extract during cooking so they catch grease as intended.

Dripping filters are a clear sign they’re full. Changing them now reduces the fuel above the cooking and the plenum may need a clean as well.
