How we handle canopy cleaning in Highfield
We clean canopies in Highfield when the kitchen is not cooking: after service, overnight or at the weekend. Cooking equipment is turned off and cooled, then covered so the kitchen is ready when we go. Typical jobs include a canopy that no longer draws the smoke away and drips from the canopy onto the range, on island canopies, baffle filters and canopy light fittings.
Kitchens around a place like Highfield are often in older buildings or single-storey extensions, where the duct may cross a roof void or climb an outside wall. Long horizontal runs like that hold grease and need access panels to reach.
Every visit ends with a written report and pictures, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

What happens if it’s left?
Getting the canopy cleaned in Highfield now saves a bigger job later. The work takes a few hours for most canopies, done while the kitchen is closed. Left alone, grease keeps moving into the plenum and duct. A planned visit to Highfield fits your hours; an emergency does not.
Working hours, access and the scale of the site all affect the cost. We take each of them into account and give you a fixed price before work begins.

Your questions about canopy cleaning in Highfield
Do you work overnight in Highfield?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in Highfield needn’t be disturbed. Tell us your opening hours when you ask for a quote.
Can you get to a site in Highfield?
Yes. Villages and rural sites across the South East are part of our work, Highfield included. Let us know about access, parking and anything unusual about getting there when you book.
What happens to the filters during the clean?
The filters are removed, cleaned and put back. Each filter is checked for fit as it goes back, because gaps let grease through.
What kinds of canopies do you clean?
Single hoods, long wall canopies and island canopies alike. The survey tells us how best to clean yours, from pictures or a visit.
Will I get a report after the canopy clean?
Before and after photos go into a report, listing what was cleaned. Where the whole system is cleaned, you also get a TR19 certificate through the BESCA Vent Hygiene Elite portal.
Does the law say we must follow TR19?
No, not in itself. TR19® is the benchmark insurers, fire officers and EHOs check against, and many insurance policies ask for proof of TR19® cleaning. The law behind it is the Fire Safety Order 2005 in England and Wales.
Are you insured?
Yes. Duct Doctor is fully insured, and the details are available on request.
What does TR19 mean?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.

What we do, step by step
Everything the job needs comes with us, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. The visit takes an hour or two for one small canopy, longer where there are several. For a site near Highfield, the work is booked around your opening hours, evenings and weekends included.
- We look at the canopy, filters and troughs first.
- 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.
Getting ready for the visit
- Mention any sign-in, permit or induction we need
- Agree a time when the area can be out of use
- Make sure equipment near the work can be switched off and left to cool

Fixed quotes for canopy cleaning in Highfield
Some jobs are bigger than they look, and some smaller. The main factors:
- Access, including roofs, risers and ceiling voids
- How many systems or sites are involved
- The condition of the system
- One-off work versus a regular cycle
No two sites are the same, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.
Asking for a quote
When you call or email, these details help:
- Your last certificate, test record or report
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The times we could work without disrupting the site
- How we’d reach plant on a roof or in a plant room
Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.
Between visits
To keep the system working properly between visits:
- Wipe the canopy down at close every day
- Tell us when the canopy starts to drip
- Keep the fan on through service
- Do not scrape the canopy with metal tools
After the clean you get a photo report showing the canopy, plenum and housing before and after. The report lists what was cleaned and any part we couldn’t get to, so the record is honest and complete.
Keep the fan running throughout service and for a short while after. Turning the fan off early lets vapour settle on the hood.
Common problems we fix in Highfield
Moisture in the air mixes with the grease on the canopy. As the canopy cools, condensation forms and runs with the grease. Drips onto the cooking line are a common result.
Common reasons sites call us include:
- Grease filters blocking between washes
- Wet, greasy drips from the hood
- Fat running down the front of the hood
- Overflowing grease troughs and gutters
If you run a church or community hall kitchen, near St Paul's or elsewhere in Highfield, its extract still collects grease from every lunch and event.
What your quote should include
- Whether the figure could change on the day
- If they look at the system before pricing
- Which accreditations they hold, and whether you can check them
- Whether VAT is included
Different parts, different methods
Pub and hotel kitchens
In a pub or hotel, the canopy is often in view of staff all day, so drips and smells soon become a daily nuisance. A thorough clean puts that right.
Wall canopies
Wall canopies sit against a wall over a cooking line. Grease often collects where the canopy meets the wall, so we clean along it as well as the inner skin.
