Canopy cleaning in Ashwell, done properly

If the canopy in Ashwell is dripping, sticky or overdue a clean? Send us a photo of the hood and filters when you call us on 0345 646 2711, or email photos, and you will get a fixed price, normally within one working day. If you are dealing with a plenum thick with grease behind the filters and a canopy flagged at an environmental health inspection, we can put it right.

For a smaller kitchen near Ashwell, a TR19® clean is the same job as anywhere: canopy, filters, plenum, duct, fan and discharge. The visit is booked around your opening hours, and the journey is planned ahead.

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

Questions from Ashwell

Is Ashwell within the area you cover?

Yes. Ashwell is within the area we cover across London and the South East. Just mention lanes, gates or anything else about the site when you book.

Which fire and rescue service is responsible for Ashwell?

That is Hertfordshire Fire and Rescue Service. TR19® is not law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.

What do you need from me for a quote?

A short description and a few photos, with the address and opening hours. If we need more, we will ask.

Do you offer emergency callouts?

Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.

Are the filters cleaned too?

We take them out, clean them and put them back. We also offer a filter exchange service for between cleans.

Do you offer maintenance contracts?

Yes. We run scheduled maintenance contracts, set at the interval the system needs. Each report recommends when the next visit should be.

What’s TR19?

TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.

What types of premises do you cover?

All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. Work is timed around how each site runs.

When to call us in Ashwell

Most canopies have troughs or channels that catch running grease. If they’re not emptied, they fill and overflow, and grease ends up dripping from the canopy edge.

The symptoms we are asked about most include:

  • A canopy flagged at an environmental health inspection
  • Grease filters blocking between washes
  • Canopy gutters full of old fat
  • Smoke hanging around the canopy during service

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

What to look for in a quote

  • When the next visit should be, and why
  • What insurance they carry
  • Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
  • Whether a survey comes first

Questions to ask before you book

How it works

We’re used to working while the site is closed. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. On site, the work takes part of a shift for most kitchens, more where there are several canopies or heavy deposits. Your opening hours decide when we come to Ashwell, not ours.

  1. We start by checking the canopy, filters and plenum.
  2. Cooking equipment is left to cool and the area under the canopy protected.
  3. With the filters out, the plenum and housing are cleaned back.
  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.

Before we arrive

  • Tell us where we can park and unload
  • Clear loose items from the work area
  • Make sure someone can let us in and lock up afterwards

Aftercare tips

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

  • Refit filters the right way round and fully seated
  • Give the canopy a wipe after service
  • Keep every filter in place while cooking
  • Run the extract the whole time you’re cooking

Where the canopy is cleaned as part of a full TR19® Grease clean, a TR19 certificate is issued through the BESCA Vent Hygiene Elite portal. If the job covers only the canopy, the paperwork reflects that.

A daily wipe of the hood keeps fresh grease from baking on. It does not reach the plenum, but it stops the outside building up.

Fixed quotes for canopy cleaning in Ashwell

There’s no set price list, because no two systems are the same. What we look at:

  • The condition of the system
  • Parking and loading at the site
  • The size of the system
  • How easy every part is to reach

Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered and we will price it together.

What to send for a quote

To speed up the quote, send us:

  • Your last certificate, test record or report
  • Problems your staff have spotted
  • A few general shots of the system
  • How we’d reach plant on a roof or in a plant room

Want a quote for canopy cleaning? Please call 0345 646 2711 or drop us a line and tell us about the site. We’ll talk you through the work and give you a fixed quote before you commit to anything.

When something else is needed

An honest diagnosis matters more to us than a booking, so here’s what this work can’t put right:

  • Grease in the duct runs and risers behind the canopy
  • A canopy undersized for the equipment
  • Filters that no longer seal in the housing

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

Where we work

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

What staff can safely do

When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.

For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.

For landlords and multi-site operators

Keeping records across a portfolio is half the battle. Every visit ends with a dated report and pictures, ready to show insurers, fire officers or EHOs.

If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and photos, so each one has its own record.

Canopy cleaning around Ashwell

Food Standards Agency records include about 3 pubs, bars and clubs within roughly a mile and a half of the centre of Ashwell. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Hertfordshire Fire and Rescue Service covers Ashwell. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel. In Ashwell, food businesses are inspected by environmental health officers from North Hertfordshire council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A TR19® certificate and photo report after each clean gives you a record to show an inspector.

If you run catering at a healthcare site, such as a hospital like Fairfield Hospital about 4.8 miles south-west, the extract may need cleaning more often than a part-time kitchen. Volunteers running a hall kitchen near St Mary's Church, or anywhere in Ashwell, may not know when the extract was last cleaned, and a grease test settles it.
