Need canopy cleaning in Oval?

Leave it or put it right?

A greasy canopy is fuel directly above the flame. Flames from the range can ignite it and be pulled further into the system, where a fire is much harder to stop. Cleaning it removes that fuel. Shared walls, risers and roofs mean a problem at one London site seldom stays put.

A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. You’ll have a fixed price before any work starts.

About our canopy cleaning in Oval

For canopies and hoods in Oval, the work follows the same careful routine: we remove the filters, clean the plenum and housing, then degrease the canopy shell. You get pictures of the canopy before and after. The work covers wall canopies, plenum chambers and grease gutters, and the jobs we see most are a greasy hood noticed by an inspector and grease dripping from the canopy edge.

Kitchens in Oval, like many across London, can share a building with flats or offices, with the duct running up through shared risers. A duct fire there can reach parts of the building far from the range, which is why keeping it clean to TR19® matters.

We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

Different parts, different methods

Pub and hotel kitchens

A hotel or pub kitchen can rarely close for long. We clean the canopy overnight or between services so the kitchen keeps trading.

Grease troughs and gutters

A blocked or full trough is the usual cause of grease dripping from the canopy. Cleaning it clears the drip.

How we price canopy cleaning

Before we fix a price, we need to know a few things. We check:

  • Whether several sites go on one quote
  • One-off work versus a regular cycle
  • Any permits to work or inductions
  • Where the site is and how we reach it

Combining work into one visit or one programme can make for a more efficient booking. Mention every system or site you need covered and we will price it together.

What we need to know

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

  • How we’d reach plant on a roof or in a plant room
  • Problems your staff have spotted
  • Close-ups of filters, grilles, hatches or access panels
  • When the site is open and when it’s quiet

For a fixed quote, call us on 0345 646 2711, or send details by email and tell us the type of site, your opening hours and roughly what the system looks like. A few photos and your last certificate or report help a lot. You will normally have a quote within one working day.

Common problems we fix in Oval

However carefully a kitchen in Oval is run, the canopy still collects grease. It’s fuel, sitting directly over the burners, which is why a flare-up near a dirty canopy is so dangerous.

Look out for these warning signs:

  • Filters that never seem to stay clean
  • A filter housing caked in grease
  • Poor capture at the hood
  • Drips from the canopy onto the range

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

What your quote should include

  • What insurance they carry
  • How VAT is shown on the quote
  • Whether they recommend a next date
  • If they look at the system before pricing

Questions to ask before you book

What canopy cleaning can’t fix

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

  • Grease filters too damaged to refit (they need replacing)
  • A dirty extract fan further along the system
  • Faulty canopy lights or wiring (a job for an electrician)

If you’re not sure, just ring 0345 646 2711, or email photos and we will give you a straight answer before you book.

Grease, kitchens and Oval

The Food Standards Agency lists about 156 pubs and bars and about 64 hotels, B&Bs and guest houses as registered food businesses in Oval and the streets around it, up to about 1.5 miles out. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Night work suits London kitchens, and roads and loading bays tend to be quieter too. Fire safety in Oval falls to London Fire Brigade. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.

School kitchens, at schools like St Stephen's Church of England Primary School for example, are typically cleaned in the holidays so no lunches are lost. Where a hall near Calvary Church of God in Christ, or anywhere in Oval, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

Oval is about 1 mile north of Stockwell, in Greater London. We provide canopy cleaning for commercial premises of every kind in Oval and the rest of Greater London. Our Greater London coverage runs to 764 places, Oval among them.

Whether your site is on Lett Road, Rita Road and Wyvil Road or a nearby road, we can help. Being close to the A203 and A3204, Oval is easy for our technicians to reach at any hour. Nearby, we also carry out canopy cleaning in Kennington (1 mile north), South Lambeth (1 mile south-west), Little Portugal (1 mile south), North Brixton (1 mile south-east) and Vauxhall (1 mile north).

Looking after it afterwards

Simple habits between visits make a real difference. Our advice:

  • Never run the range with a filter out
  • Clean the hood’s outer surfaces daily
  • Refit filters the right way round and fully seated
  • Tell us when the canopy starts to drip

The report gives a recommended next clean date. It reflects how long the kitchen cooks and how much grease we removed, in line with BESA guidance.

The best thing a kitchen can do for its canopy is keep the filters clean. Keep them on a regular cleaning or exchange cycle, and never cook with one missing. Less grease gets into the plenum as a result.

What happens on the day

We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool before any work starts, and floors and nearby surfaces are sheeted. The work itself takes part of a shift for most kitchens, more where there are several canopies or heavy deposits. Managed blocks in London often need contractors booked in ahead, and we’re happy to deal with the agent directly for a site in Oval.

  1. The canopy is checked from pictures or on a visit.
  2. Out of hours, the range is switched off, cooled and covered.
  3. With the filters removed, the plenum and filter channels are cleaned.
  4. The canopy shell, seams, troughs and gutters are degreased inside and out.
  5. Filters are refitted, the area cleaned down and the photo report put together.

Before we arrive

  • Agree a time when the area can be out of use
  • Mention any locked doors, roof access or ceiling voids
  • Make sure equipment near the work can be switched off and left to cool

Getting a quote

Advice

Common questions in Oval

Who carries out food hygiene inspections in Oval?

The local authority for Oval is Lambeth 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.

Do you work overnight in Oval?

Yes, nights and weekends are routine for us. The site is handed back ready to open. Tell us your opening hours when you ask for a quote.

Is there a survey before the work?

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

Who is the responsible person?

In the words of the Fire Safety Order 2005, it’s the responsible person. That’s generally the employer or the person in control of the premises, and in shared buildings more than one person can have duties. Your lease and fire risk assessment should make it clear.

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. We work with hotels, schools, care homes, offices, retail and leisure sites.

How much of the canopy do you clean?

We clean the canopy inside and out, along with its seams and grease channels. The plenum and filter housing behind the filters are cleaned too.

Which canopies and hoods do you clean?

Wall and island canopies, long cooking-line hoods and small single hoods. Each one is cleaned inside and out, with the plenum behind the filters.

Will we have to shut during the visit?

Not usually. Out-of-hours visits keep the disruption down. Larger jobs can be phased over several visits to keep things running.
