Professional canopy cleaning in and around Mitcham, booked around your opening hours and finished with a written report and photos.

Multi-site and managed buildings
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
Keeping records across a portfolio is half the battle. Each visit ends with a dated report and photos, so you can show an insurer or inspector what was done at each site.
Canopy cleaning in Mitcham
If the canopy in Mitcham is dripping, sticky or overdue a clean? A photo of the canopy and filters is a good start when you call us on 0345 646 2711, or email photos, and we’ll send you a fixed quote for canopy cleaning, normally within one working day. Typical jobs include greasy streaks across the canopy and smoke hanging around the canopy during service, across baffle filters, grease gutters and plenum chambers.
London kitchens are often tucked into basements or the back of a building, and the duct may run up through several floors before it discharges at the roof. In Mitcham, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

Why act early in Mitcham
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. Choosing the date yourself beats having a fault choose it for you.
Working hours, access and the scale of the site all affect the cost. We take each of them into account, and the price is fixed before any work starts.

Staff cleaning versus specialist work
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
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.
Common problems we fix in Mitcham
A canopy with gaps around its filters lets grease straight through. More grease reaches the plenum and housing than they’re designed to take, which shows up as heavy deposits when the filters come out.
Clients usually contact us when they notice something like this:
- Condensation and grease dripping together
- Overflowing grease troughs and gutters
- A greasy hood noticed by an inspector
- Smoke hanging around the canopy during service
Bursars and site managers at schools such as St Thomas of Canterbury Catholic Primary School tend to book extract cleaning for when the kitchen is empty.

What happens on the day
Protection comes first: floors, worktops and anything near the work are covered. Then we make the system safe and start. It takes an hour or two for one small canopy, longer where there are several, and the area is cleaned down before we leave. In a London area like Mitcham, parking, loading and building access are planned before the day of the work.
- The canopy is checked from photos or on a visit.
- Once the kitchen has closed, the cooking line is cooled and sheeted.
- We lift out the filters and scrape the plenum and housing.
- Inside and out, the hood and its troughs are cleaned.
- We put the filters back, tidy up and photograph the finished canopy.
Before we arrive
- Mention any sign-in, permit or induction we need
- Tell us the best time to work, such as after service or at a weekend
- Clear loose items from the work area

Every kitchen among them that cooks under a canopy has a hood, plenum and filters collecting grease. Fire safety in Mitcham falls to London Fire Brigade.
