Canopy cleaning in Rosehill
We clean canopies in Rosehill when the kitchen isn’t cooking: evenings, overnight, early mornings or weekends. Cooking equipment is turned off and cooled, then covered, and the kitchen is left ready for the next service. If you’re dealing with poor capture at the hood and a plenum thick with grease behind the filters, we can put it right.
Across London, many commercial kitchens are squeezed into basements and narrow back-of-house spaces, with extract ducts that can climb several floors to discharge at roof level. In Rosehill, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.

Leave it or put it right?
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. In a London building, a problem in a duct, damper or fan rarely stays in one unit.
What you pay reflects the actual work. That’s why we survey first, from pictures or on site, and the price is agreed before we start.

Rosehill questions
Can you work in Rosehill outside opening hours?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Your opening times are the first thing we ask for.
Which fire authority looks after Rosehill?
Rosehill is in the area of London Fire Brigade. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
Who has the legal duty for fire safety?
The law calls them the responsible person. That’s generally the employer or the person in control of the premises, and in shared buildings more than one person can have duties. If you’re not sure, check your lease and fire risk assessment.
Do you offer maintenance contracts?
Yes. Tell us what you have and how it’s used, and we’ll suggest a schedule and quote for it.
Do you provide photos of the cleaned canopy?
A photo report, with before and after pictures of the canopy and plenum. It also gives a recommended date for the next clean.
Do you work in Rosehill?
Yes. We work across Greater London, Surrey, Kent, Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, and that includes Rosehill.
Are the filters cleaned too?
Filters are removed so we can clean the plenum and housing, then cleaned and refitted. We also offer a filter exchange service for between cleans.
How long does canopy cleaning take?
Allow part of a shift for most kitchens, more where there are several canopies or heavy deposits. We will confirm how long when we quote.
Different parts, different methods
Wall canopies
A long wall canopy may hold several sections of filters. We work along the canopy section by section, with photos for each.
Pub and hotel kitchens
In pubs and hotels, the kitchen may be busy for much of the day. Long hours mean the canopy collects grease fast, so it may need cleaning between full TR19 cleans.
Landlords, agents and facilities managers
Keeping records across a portfolio is half the battle. Every visit ends with a dated report and pictures, ready to show insurers, fire officers or EHOs.
Facilities teams in offices, schools and healthcare sites book us too across Greater London. Larger estates can be phased building by building around the people who use them.
What happens on the day
We start by comparing what we find with the survey or your pictures. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes a few hours, depending on the size of the canopy and how much grease has built up. Expect the work in Rosehill to happen after your last customer leaves, not during trading.
- We start by checking the canopy and what’s behind its filters.
- We protect everything below once it has cooled.
- Thick grease is scraped away before the canopy is 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.
Preparing for the visit
- Move anything stored near the system
- Arrange a key holder or contact on site
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
Get a fixed quote
To get a fixed quote, call 0345 646 2711 or drop us a line and tell us the type of site, your opening hours and roughly what the system looks like. A few pictures and your last certificate or report help a lot. You will normally have a quote within one working day.

Aftercare tips
How long the results last depends on use and care. Here’s what we suggest:
- Use non-abrasive cloths on the hood
- Never run the range with a filter out
- Keep the fan on through service
- Give the canopy a wipe after service
Keep the photo report with your maintenance log where an inspector can see it. Photos of a clean canopy and plenum make the record easy to follow.
Empty the grease troughs and cups before they fill. Most canopy drips start with a full trough, so make emptying them part of the closing routine.

Kitchen extracts in Rosehill
There are about 164 restaurants, cafés and canteens and about 93 sandwich bars and takeaways across Rosehill and its immediate surroundings (about a mile and a half), according to the Food Standards Agency’s register. Each canopy in those kitchens catches grease on the inside of the hood and behind the filters. Rosehill sits within the area of London Fire Brigade. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract. Night work suits London kitchens, and roads and loading bays tend to be quieter too.
Healthcare kitchens, like those at hospitals such as St Helier Hospital (about within half a mile south), often cook for long hours, which puts them in BESA’s heavier-use bands. If you run a church or community hall kitchen, near St Peter's Church or elsewhere in Rosehill, its extract still collects grease from every lunch and event. If you look after a school kitchen, at a school such as Tweeddale Primary School or anywhere near Rosehill, the holidays are the usual time for a TR19® clean.

In-house cleaning or a specialist?
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.
When it’s something else
A few issues sit outside what this work can do:
- Grease filters too damaged to refit (they need replacing)
- A dirty extract fan further along the system
- A canopy undersized for the equipment
Not sure which it is? You can call us on 0345 646 2711 or email us and we’ll tell you honestly before booking.
