Greater London · Canopy and hood cleaning
Canopy Cleaning in Richmond
Deep cleaning of kitchen canopies, hoods, plenums and grease filters, inside and out for commercial sites in Richmond and across Greater London. CHAS, SafeContractor and ISO 9001, and fully insured.
- Filters that clog soon after cleaning
- Condensation running down the canopy
- Overflowing grease troughs and gutters
The process
Every visit runs to the same pattern: sheeting and protection first, isolate whatever needs isolating, carry out the canopy cleaning, tidy up and leave you the report. On site, the work takes a few hours, depending on the size of the canopy and how much grease has built up. Expect the work in Richmond to happen after your last customer leaves, not during trading.
- Diagnosis first: we look behind the filters as well as at the hood.
- 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
- Mention any locked doors, roof access or ceiling voids
- Arrange a key holder or contact on site
- Allow time for equipment near the work to be turned off and cool down

What else we do in Richmond
Canopy cleaning in Richmond: the local picture
Food Standards Agency records include about 49 pubs, bars and clubs and about 6 hotels and B&Bs within roughly a mile and a half of the centre of Richmond. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Richmond 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 Richmond get their food hygiene inspections from Richmond-Upon-Thames council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Before-and-after photos from each clean are a simple way to show the extract is in hand.
A kitchen near Richmond station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval. If you run catering at a healthcare site, such as a hospital like South Middlesex Hospital about 1.6 miles west, the extract may need cleaning more often than a part-time kitchen.
Richmond is about 5 miles south-west of Kensington, in Greater London. We provide canopy cleaning for businesses, landlords and public buildings in Richmond and the rest of Greater London. Richmond is one of 764 towns, villages and districts in Greater London where we work for commercial clients. Our London page covers sites nearby (9 miles or so).

What staff can safely do
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Honest limits
An honest diagnosis matters more to us than a booking, so here’s what this work can’t put right:
- A fan that cannot pull enough air because it’s worn out
- Bent or broken filters
- Ductwork and fans beyond the canopy (those need a full TR19 clean)
If you’re not sure, just ring 0345 646 2711 or drop us a line and we’ll give you a straight answer before you book.
Where we work
- Island canopies
- Canopy light fittings
- Plenum chambers
- Baffle filters
- Wall canopies
- Grease gutters
Leave it or put it right?
A blocked plenum and clogged filters cut the airflow at the canopy. Smoke and heat hang around the cooking line, and the fan works harder for less. Cleaning restores the path the air should take. A building in Richmond may have flats or offices above and alongside, and a fault in the system can affect them too.

FAQs for Richmond
Which fire and rescue service is responsible for Richmond?
It’s London Fire Brigade, which covers Richmond. TR19® isn’t law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
Can you work in Richmond outside opening hours?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Richmond needn’t be disturbed. Just ring 0345 646 2711 or use the quote form with your opening times and we will plan around them.
Do you offer maintenance contracts?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, to suit the system and how it’s used.
How long will it take to clean the canopy?
That depends on the size of the canopy and how much grease is on it. As a guide, it takes part of a shift for most kitchens, more where there are several canopies or heavy deposits.
What does canopy cleaning cost?
There’s no set price, as it depends on the job: the size of the system, its condition, access and when we can work. We fix the price before work begins.
Is there a survey before the work?
Yes. For many sites, photos and a few details are enough, while bigger or harder-to-see systems are surveyed on site.
Who is responsible for fire safety on the premises?
The Fire Safety Order 2005 calls them the responsible person: normally the employer or whoever controls the premises. In shared or managed buildings, a landlord, facilities manager or managing agent can share the duty.
Can you look after several sites?
Yes. One number covers all your sites in our area, with visits on a regular schedule.
Signs you need canopy cleaning in Richmond
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 before what gets through reaches the plenum.
If you notice any of these, it’s worth a diagnosis:
- Condensation and grease dripping together
- Heavy deposits behind the grease filters
- A sticky, discoloured canopy
- A canopy that no longer draws the smoke away
If you look after a school kitchen, at a school such as The Vineyard School or anywhere near Richmond, the holidays are the usual time for a TR19® clean.
Questions to ask before you book
- What records you will receive afterwards
- When the next visit should be, and why
- Whether the quote is based on a survey or pictures
- What hours they’ll be on site
Looking after it afterwards
How long the results last depends on use and care. Here’s what we suggest:
- Check and empty canopy gutters regularly
- Refit filters the right way round and fully seated
- Run the extract the whole time you’re cooking
- Clean the baffle filters often
File the report alongside your fire risk assessment where an inspector can see it. Photos of a clean canopy and plenum make the record easy to follow.
Keep the fan running throughout service and for a short while after. Turning the fan off early lets vapour settle on the hood.
How we price canopy cleaning
Before we fix a price, we need to know a few things. We look at:
- How many systems or sites are involved
- The size of the system
- Whether it’s a one-off visit or part of a schedule
- Working hours and out-of-hours timing
We don’t list prices on the website, because each job is priced on what it involves. Call for a fixed quote, and we will talk you through it.
Helping us quote
Photos and a few facts are often enough to price the work. Send what you can of the following:
- Any symptoms, from odd noises to smells or leaks
- The paperwork from the last visit, if you have it
- When the site is open and when it’s quiet
- Where the site is and what kind of site it is
Getting a quote does not take long. Call or email with a few details and you will usually have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
