In-house cleaning or a specialist?
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That’s our job.
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We’ll take a look and give you a fixed quote.
Canopy cleaning in Northaw Valley, done properly
A greasy canopy tells an inspector a lot before they’ve opened anything. What is not seen, behind the filters, tends to be worse. Canopy cleaning deals with both, so the hood looks right and works properly. If you have overflowing grease troughs and gutters and drips from the canopy onto the range, we can help.
In a small place like Northaw Valley, kitchens are often in older or extended buildings, with long single-storey duct runs, where grease settles in the flat sections. Access, parking and timings are agreed before the day.
Insurers, fire officers and environmental health officers all look at records. That’s why every job is written up in a report with photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

What we do, step by step
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool before work begins, and floors and nearby surfaces are sheeted. On site, it takes a few hours for most canopies. Pictures of the system and its access let us plan the work in Northaw Valley before we set off.
- 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.
- Heavy deposits come off by hand, then the surfaces are degreased.
- We finish the plenum, troughs and canopy and check them over.
- You get pictures of the result and a recommended date for the next clean.
How to prepare
- Mention any parking or loading restrictions
- Find the previous report, if there is one
- Mention any locked doors, roof access or ceiling voids

What we are called out for in Northaw Valley
Air straight off the range hits the canopy first. Fat in that air settles on the inside of the hood, in its seams and on the filters, and the plenum behind them collects the rest.
If you notice any of these, it’s worth a diagnosis:
- A filter housing caked in grease
- A canopy that no longer draws the smoke away
- Filters that never seem to stay clean
- Greasy streaks across the canopy
If you look after a school kitchen, at a school such as St. John's Senior School or anywhere near Northaw Valley, the holidays are the usual time for a TR19® clean.
Questions to ask before booking
- What insurance they carry
- What happens if part of the system can’t be accessed
- Which accreditations they hold, and whether you can check them
- If the quote is a fixed price or an estimate
Multi-site and managed buildings
Managing agents often deal with us directly. Send the address, what’s needed and how access works and we will come back with a fixed quote.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
Between visits
Aftercare is simple, and it makes the next visit easier:
- Clean the baffle filters often
- Clean the hood’s outer surfaces daily
- Tell us when the canopy starts to drip
- Empty the grease troughs before they fill
A before and after photo report follows the clean. The report lists what was cleaned and any part we couldn’t get to, so the record is honest and complete.
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. The plenum behind them stays cleaner.
What affects the cost of canopy cleaning
We quote each job individually. These are the things that affect it:
- What state the system is in
- Access, including roofs, risers and ceiling voids
- Site requirements such as sign-in and permits
- Working hours and out-of-hours timing
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we will go through it with you.
Helping us quote
There’s no need for technical detail. Just send:
- Photos showing the whole system and its surroundings
- Any previous report or certificate
- Your opening hours and when the area is out of use
- Close-ups of filters, grilles, hatches or access panels
Photos are the quickest way to a quote: 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.
