Leave it or put it right?

Grease dripping from the hood can fall onto food, pans and worktops. It’s a food hygiene concern as much as a fire concern, and EHOs look at the cleanliness of the premises and equipment. A fault that closes a site in a village like Bower Heath affects everyone who depends on it.

Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll explain each part.

  • In business since 2009
  • CHAS and SafeContractor accredited, with ISO 9001

How we handle canopy cleaning in Bower Heath

We have been cleaning kitchen canopies since we started trading in 2009. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’re fully insured, with CHAS, SafeContractor and ISO 9001. Typical jobs include fat running down the front of the hood and condensation running down the canopy, across wall canopies, plenum chambers and island canopies.

Rural kitchens often have long, low duct runs through a roof space or along an outside wall, and those horizontal sections are where grease settles. We agree access and timings in advance.

Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

What we do, step by step

Your staff don’t need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Before we leave, the area is tidied and the paperwork follows. Photos of the system and how to reach it help us plan a visit to Bower Heath.

  1. First the canopy is surveyed, by pictures or in person.
  2. Equipment below is switched off and left to cool, then sheeted.
  3. We remove the grease filters and clean the plenum and filter housing.
  4. The canopy is cleaned inside and out, including troughs and seams.
  5. Clean filters are refitted and before and after photos go into your report.

Before we arrive

  • Mention any sign-in, permit or induction we need
  • Let us know when the site is closed or quiet
  • Make sure someone can let us in and lock up afterwards

Bower Heath kitchens: local notes

The FSA’s food hygiene register shows about 34 cafés, restaurants and staff canteens and about 8 takeaways within about 1.5 miles of central Bower Heath. Each canopy in those kitchens catches grease on the inside of the hood and behind the filters. In Bower Heath, food businesses are inspected by environmental health officers from St Albans City council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Before-and-after pictures from each clean are a simple way to show the extract is in hand. Bower Heath sits within the area of Hertfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.

School kitchens, at schools like Sauncey Wood Primary School for example, are normally cleaned in the holidays so no lunches are lost. Healthcare kitchens, like those at hospitals such as St Albans City Hospital (about 5.2 miles south), often cook for long hours, which puts them in BESA’s heavier-use bands.

Bower Heath is about 1 mile north of Harpenden, in Hertfordshire. From the centre of Bower Heath to the outskirts, canopy cleaning is available to all kinds of commercial premises, from a single unit to a large public building. Our area takes in 381 places across Hertfordshire, large and small. There’s also a page for Milton Keynes, about 23 miles away.

FAQs for Bower Heath

Do you work overnight in Bower Heath?

Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Tell us your opening hours when you ask for a quote.

Which fire authority looks after Bower Heath?

Bower Heath is in the area of 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.

How much of the canopy do you clean?

Everything from the outer face to the plenum behind the filters. Troughs, gutters and filter housings are cleaned too.

Who has the legal duty for fire safety?

The law calls them the responsible person. It’s normally the employer, or whoever controls the building, and where several people have control, each can have duties. Your lease and fire risk assessment should make it clear.

Can one contract cover all our sites?

Yes. One number covers all your sites across London and the South East, and visits can be set on a regular cycle.

What’s TR19?

It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked, and it takes a risk-based approach.

What types of premises do you cover?

Any commercial site with kitchens or ventilation, from a single café to a large school. We work with hotels, schools, care homes, offices, retail and leisure sites.

Do you survey before quoting?

Yes. We always survey first, either from photos and details you send or on a site visit. A fixed quote follows.

Aftercare tips

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

  • Wipe the canopy down at close every day
  • Run the extract the whole time you’re cooking
  • Use non-abrasive cloths on the hood
  • Flag any change in how the canopy behaves

The kitchen is handed back clean, with the sheeting gone and the waste removed. Filters are back in place and seated properly ready for the next service.

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 make sure they’re all in place before cooking. Less grease gets into the plenum as a result.

Multi-site and managed buildings

Keeping records across a portfolio is half the battle. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.

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

Different parts, different methods

Wall canopies

Long wall canopies often have several filter banks. We work along the canopy section by section, with photos for each.

Island canopies

Island canopies hang over cooking in the middle of the kitchen, which means grease settles on all four sides. We clean all of them, inside and out.

What a clean will not put right

We’ll always give you a straight diagnosis, so here’s what canopy cleaning won’t do:

  • Electrical faults in the canopy
  • A dirty extract fan further along the system
  • Weak extraction caused by a failing fan motor

If in doubt, give us a ring on 0345 646 2711 or use the quote form and we will say what we think before booking.

What we work on in Bower Heath

Do you need canopy cleaning in Bower Heath?

Any canopy in Bower Heath that is used for cooking will gather grease in the end. It’s fuel, sitting directly over the burners, which is why a flare-up near a dirty canopy is so dangerous.

It’s time to book a visit if you see:

  • Filters that never seem to stay clean
  • Fat running down the front of the hood
  • Condensation running down the canopy
  • Greasy streaks across the canopy

Shaw's Corner, about 3.2 miles east, is one of the historic houses near Bower Heath; if you run event catering at a venue like that, cleans can be booked between functions.

What your quote should include

  • When the next visit should be, and why
  • What happens if part of the system cannot be accessed
  • Whether VAT is included
  • Whether the whole system is included, or only the parts that are easy to reach
