How we handle canopy cleaning in Whempstead
Dripping edges and a sticky hood are the first things a visitor notices. What is not seen, behind the filters, tends to be worse. We clean both, so the canopy is clean where it shows and where it doesn’t. The work covers plenum chambers, island canopies and canopy light fittings, and the jobs we see most are wet, greasy drips from the hood and poor capture at the hood.
Work in a small place like Whempstead starts with a call to agree access and timings, and the clean covers the whole system, as it would anywhere: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
Think of the report as the system’s health record: a dated account with photos of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

How it works
The visit has three parts: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and pictures. Most of the time goes on the work itself, and that takes a few hours for most canopies. Visits to a village like Whempstead are booked in advance, at a time that suits whoever runs the site.
- We start by checking the canopy and what’s behind its filters.
- Equipment is turned off and cooled, and the area under the canopy is protected.
- Thick grease is scraped away before the canopy is degreased.
- Plenum, housing, troughs and canopy are all cleaned and checked.
- You get pictures of the result and a recommended date for the next clean.
Before we arrive
- Have your last certificate or report to hand
- Clear the space around the work
- Let us know how we reach the system, including roofs, risers and plant rooms

What happens if it’s left?
Leaving the canopy until the next full clean can mean months of build-up. In a busy kitchen, the canopy and plenum can need attention between TR19 cleans, and readings or a look behind the filters will show it. If the system at a site near Whempstead fails, there may be nowhere nearby to move to.
Working hours, access and the scale of the site all affect the cost. Each of those is built into the quote and give you a fixed price before work begins.

Whempstead kitchens: local notes
The Food Standards Agency lists about 4 pubs, bars and clubs as registered food businesses across Whempstead and its immediate surroundings (about a mile and a half). A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Whempstead sits within the area of Hertfordshire Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel. It’s East Hertfordshire council that sends environmental health officers to food businesses in Whempstead. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A dated certificate in the maintenance file answers the question before it’s asked.
School kitchens, at schools like Munden Church of England Voluntary Controlled Primary School for example, are typically cleaned in the holidays so no lunches are lost. Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Whempstead is Hertford County Hospital, about 5.4 miles south.

Your questions about canopy cleaning in Whempstead
Who enforces fire safety at workplaces in Whempstead?
That is Hertfordshire Fire and Rescue Service. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Do you work at weekends in Whempstead?
Yes. We work evenings, overnight and at weekends. The work in Whempstead can fit around your hours. When you give us a ring on 0345 646 2711, or send details by email, mention when the site is quiet.
How long will it take to clean the canopy?
It takes an hour or two for one small canopy, longer where there are several. Your quote will give a time.
Do you have insurance?
Yes, fully. We also hold CHAS and SafeContractor, for sites that check contractor safety.
What about areas you can’t get to?
Anything we cannot reach goes on the report, with a note of where it is, and we explain what access is needed, for example new access panels.
Can you set up regular visits?
Yes, of course. Send details of the systems and how they’re used and we will propose a schedule with a fixed quote.
Are you accredited?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We have been trading since 2009 and we’re fully insured.
What should I send you?
Where the site is, what it is and when it’s open, along with a few photos and any previous report.
Landlords, agents and facilities managers
We also work for facilities teams across offices, schools and healthcare across Hertfordshire. Larger estates can be phased building by building to keep disruption down.
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements, and we will send a fixed quote.
What affects the quote in Whempstead
You’ll get a fixed price before work begins. It’s based on:
- When the work can happen, such as evenings, overnight or weekends
- The scale of the work
- Whether it’s a one-off visit or part of a schedule
- Travel, parking and unloading
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. The price is fixed before any work starts.
What we need to know
When you contact us, it’s useful to have:
- Any symptoms, from odd noises to smells or leaks
- The site address and the type of premises
- Photos showing the whole system and its surroundings
- How we’d reach plant on a roof or in a plant room
The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.
When it’s something else
An honest diagnosis matters more to us than a booking, so here’s what canopy cleaning won’t do:
- Grease in the duct runs and risers behind the canopy
- Faulty canopy lights or wiring (a job for an electrician)
- Grease filters too damaged to refit (they need replacing)
If in doubt, ring 0345 646 2711, or send details by email and we will say what we think before you book.
Where we work
- Wall canopies
- Canopy light fittings
- Plenum chambers
- Baffle filters
- Grease gutters
- Island canopies
Signs you need canopy cleaning in Whempstead
A canopy in Whempstead picks up grease at much the same rate as one anywhere else with the same cooking: it comes down to how long the kitchen cooks and what’s on the menu. High-heat cooking coats it fastest.
Look out for any of the following:
- Greasy streaks across the canopy
- Fat running down the front of the hood
- Condensation and grease dripping together
- Grease filters blocking between washes
Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Aston Bury is about 2.6 miles west), access may need planning.
Before booking anyone
- What insurance they carry
- Which accreditations they hold, and whether you can check them
- Whether the quote is based on a survey or pictures
- What hours they’ll be on site
What staff can safely do
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
