Perivale questions

Who inspects food businesses in Perivale?

The local authority for Perivale is Ealing council, and its environmental health team does the inspecting. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.

Does London parking affect a job in Perivale?

Tell us where a van can stop near your site in Perivale, and about any building rules on loading. Much of our London work is done overnight, which helps.

Who is responsible for fire safety on the premises?

It depends on the building. The Fire Safety Order 2005 puts the duty on the responsible person, which may be the employer, owner, landlord, facilities manager or managing agent.

Do you clean the grease filters as part of a canopy clean?

We remove the filters to reach the plenum, and they’re cleaned before going back in. We will tell you if any need replacing.

Can I just have the canopy cleaned instead of the whole system?

TR19® Grease is about the whole extract, from canopy to discharge. Cleaning the canopy alone leaves the ducts, risers and fan untouched, and the report will say what was covered.

What kinds of canopies do you clean?

Wall and island canopies, long cooking-line hoods and small single hoods. The method is the same: filters out, plenum and housing cleaned, canopy degreased inside and out.

Do you clean inside the canopy as well as outside?

We clean the canopy inside and out, including the seams, troughs and gutters. With the filters out, the plenum and housing are cleaned as well.

Can you look after several sites?

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

Canopy cleaning for kitchens and businesses in Perivale

The canopy is where the extract system breathes in. A dirty canopy passes more grease further into the system. Our diagnosis starts there, and the cure is a thorough clean of the hood, the plenum and the filter housing. If you have poor capture at the hood and a canopy flagged at an environmental health inspection, we can put it right, from island canopies, wall canopies and baffle filters onwards.

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. For a kitchen in Perivale, that usually means a longer system to clean and more access panels to plan around.

Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

When it’s something else

It’s worth knowing the limits before booking:

  • Grease filters too damaged to refit (they need replacing)
  • A canopy too small for the cooking under it (that is a design question)
  • Electrical faults in the canopy

If in doubt, ring 0345 646 2711 or email us and we will say what we think.

What we work on in Perivale

  • Plenum chambers
  • Canopy light fittings
  • Baffle filters
  • Island canopies
  • Grease gutters
  • Wall canopies

In-house cleaning or a specialist?

Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.

Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That is our job.

Part by part

Wall canopies

At the back of the canopy, behind the filters, grease builds up unseen. We remove the filters to reach it and degrease it properly.

Pub and hotel kitchens

Pub and hotel kitchens can cook from breakfast to late evening. That’s a lot of grease on the canopy, so it may need cleaning between full TR19 cleans.

How we price canopy cleaning

A fixed price needs a few facts first. We check:

  • Whether it’s a one-off visit or part of a schedule
  • Access, including roofs, risers and ceiling voids
  • When the work can happen, such as evenings, overnight or weekends
  • How big the system is

Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, which can make the next visit longer. If you’re not sure what’s needed, call 0345 646 2711 or use the quote form for straight advice and a fixed quote.

Helping us quote

Photos let us diagnose from a distance. Try to include:

  • The paperwork from the last visit, if you have it
  • Any symptoms, from odd noises to smells or leaks
  • A few general shots of the system
  • How we’d reach plant on a roof or in a plant room

For a fixed quote, call us on 0345 646 2711 or use the quote form and tell us the type of site, your opening hours and roughly what the system looks like. A few pictures and your last certificate or report help a lot. We usually come back within one working day.

What canopy cleaning looks like in Perivale

There are about 174 restaurants, cafés and works canteens and about 120 sandwich bars and takeaways across Perivale and its immediate surroundings (about a mile and a half), according to the Food Standards Agency’s register. Wherever there’s a canopy over the cooking, its hood and plenum collect grease with every service. Perivale sits within the area of London Fire Brigade. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises. Kitchens in Perivale get their food hygiene inspections from Ealing council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A dated certificate in the maintenance file answers the question before it’s asked.

If you run a café or takeaway near South Greenford station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits. Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Perivale is Clementine Churchill Hospital, about 1.9 miles north.

Perivale is about 1 mile east of Greenford, in Greater London. Perivale gets the same approach as every site we work on: diagnosis first, a fixed price, out-of-hours working where needed and a written report with photos. Perivale is one of 764 places in Greater London we cover for canopy cleaning. We also work in London, around 10 miles away.

Postcode districts we cover here for canopy cleaning: UB6, HA0 and W5. If you need canopy cleaning at premises on Lee Road, Wicket Road and Bilton Road or a nearby road, we can help.

Signs you need canopy cleaning in Perivale

Steam and condensation make canopy grease harder to deal with. As the canopy cools, condensation forms, carrying grease with it. Drips onto the cooking line are a common result.

If you notice any of these, it’s worth a diagnosis:

  • Grease filters blocking between washes
  • A canopy that no longer draws the smoke away
  • Fat running down the front of the hood
  • Condensation and grease dripping together

Bursars and site managers at schools such as St John Fisher Catholic Primary School tend to book extract cleaning for when the kitchen is empty.

Before you book anyone

  • How areas they can’t reach will be recorded
  • What records you’ll receive afterwards
  • Whether the whole system is included, or only the parts that are easy to reach
  • Which accreditations they hold, and whether you can check them

How to choose an extract cleaning contractor

Keeping the system healthy

After the visit, a few habits help the work last:

  • Refit filters the right way round and fully seated
  • Clean the baffle filters often
  • Tell us when the canopy starts to drip
  • Clean the hood’s outer surfaces daily

After the clean you get a photo report showing the canopy, plenum and housing before and after. The report lists what was cleaned and any part we couldn’t get to, so the record is honest and complete.

Do not let canopy gutters fill to the brim. Overflowing troughs are the usual cause of drips onto the range, so make emptying them part of the closing routine.

What we do, step by step

Your staff don’t need to do much on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Afterwards, the area is left tidy and the written report follows. Security desks and permits-to-work are routine in London, so let us know what your building in Perivale needs from us.

  1. We look at the canopy first, from photos or on a visit.
  2. Cooking equipment is left to cool and the area under the canopy protected.
  3. We remove the grease filters and clean the plenum and filter housing.
  4. We degrease the canopy shell, its seams and the grease troughs.
  5. Clean filters are refitted and before and after photos go into your report.

How to prepare

  • Make sure equipment near the work can be switched off and left to cool
  • Mention any locked doors, roof access or ceiling voids
  • Make sure someone can let us in and lock up afterwards
