Kitchen extracts in Childs Hill
Food Standards Agency records list about 303 restaurants, cafés and canteens and about 100 sandwich bars and takeaways within roughly a mile and a half of the centre of Childs Hill. Where they cook under a canopy, grease doesn’t stop at the filters: it settles along the duct and up the riser. In Childs Hill, food businesses are inspected by environmental health officers from Barnet council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Before-and-after photos from each clean are a simple way to show the extract is in hand. London jobs normally start after the last service, with loading and roof access agreed with the building first.
School kitchens, at schools like All Saints' CofE Primary School NW2 for example, are usually cleaned in the holidays so no lunches are lost. If you run catering at a healthcare site, such as a hospital like New End Hospital about 0.9 miles east, the extract may need cleaning more often than a part-time kitchen.

About our ductwork cleaning in Childs Hill
Grease in a duct is hidden, which is exactly why it’s dangerous. A flare-up drawn up from the range can light it, carrying a fire along the duct and into rooms far from the kitchen. Cleaning the duct takes that fuel away. We are often asked to deal with grease pooling at the foot of the riser and readings above 200 microns from a grease thickness test, on attenuators, vertical risers and bends and junctions.
In London, few kitchens can spare a day to close, so extract cleaning in Childs Hill is typically done overnight, after the last service. Before the clean, we agree loading, parking and roof access with whoever manages the building.
A written report with pictures follows every visit, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Do you need ductwork cleaning in Childs Hill?
Damaged or poorly fitted filters let more grease into the duct. More grease reaches the ductwork than it should, and build-up speeds up.
Keep an eye out for any of the following:
- A duct clean needed for an insurer
- Years of grease along the duct floor
- Stale grease odours from the duct
- A grease test showing the duct is overdue
Church and community hall kitchens, near All Saints or anywhere around Childs Hill, are easy to forget, but their extracts collect grease like any other.
Before booking anyone
- Whether the figure could change on the day
- Proof of accreditation you can verify
- What paperwork you get at the end
- Whether they’re fully insured
Keeping the system healthy
Think of this as the after-treatment advice, short and simple:
- File each certificate and photo report in the maintenance log
- Keep grease filters clean and fitted whenever you cook
- Run the extract fan throughout service
- Book the next clean before the recommended date
The report names every part of the duct that couldn’t be reached, with the reason. We can fit access panels so those sections are cleaned next time.
Grease that never reaches the duct never needs cleaning out of it. Keep the filters clean, well fitted and in place whenever you cook.
The process
On the day, we arrive 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 we start, and the area around the work is covered and protected. On site, it takes from a few hours to more than one visit, depending on duct length and access. A name and number for whoever controls access to the building in Childs Hill saves time on the night.
- We start by working out how the duct runs and where it can be opened.
- Grease readings are taken at set points along the duct.
- Access panels are opened and heavy deposits scraped out by hand.
- Next the ducts and risers are degreased, using whatever suits the deposit.
- Readings and photos are repeated and any section we couldn’t reach is recorded.
Preparing for the visit
- Mention any parking or loading restrictions
- Name a contact who can let us in at the agreed time
- Clear the space around the work
Ask for a quote
Here’s what helps us quote: the address, the type of site and when it’s open, photos of the system and any previous report or certificate. Once you have those, give us a ring on 0345 646 2711 or send us an email.

Your questions about ductwork cleaning in Childs Hill
Which fire and rescue service is responsible for Childs Hill?
That’s London Fire Brigade. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
How do you handle parking and loading in Childs Hill?
A loading bay, a visitor permit or off-street space near the site in Childs Hill makes the visit easier to plan. Night visits tend to make loading easier on London streets.
What types of premises do you cover?
Any site with a kitchen or a ventilation system to look after, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
What shows that the ducts need a clean?
Start with the date of the last clean. If it’s overdue, or there is not one, a clean is due, and grease readings will confirm how urgent it is.
What is TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.
Can you look after several sites?
Yes. Send the list of sites and the work at each and you’ll get one fixed quote.
Do you cover Childs Hill?
Yes. Our area takes in London and the counties of South East England, Childs Hill included.
Do you offer emergency callouts?
Yes, 24/7. Our office is open from 8am to 6pm on weekdays, with the emergency line covering every other hour.

What affects the quote in Childs Hill
The diagnosis comes before the price. The main factors are:
- How easy every part is to reach
- Where the site is and how we reach it
- One-off work versus a regular cycle
- When the work can happen, such as evenings, overnight or weekends
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.
What to send for a quote
What to send for a quote:
- Photos showing the whole system and its surroundings
- Your last certificate, test record or report
- Detail shots of panels, filters and grilles
- How we’d reach plant on a roof or in a plant room
Quotes are quick. Call or email with a few details and you will normally have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
When it’s something else
Before you book, it helps to know what’s not included:
- A worn-out fan that needs replacing
- Ductwork that was poorly designed
- Leaking duct joints that need repair
If in doubt, ring 0345 646 2711 or drop us a line and we will say what we think.
What we work on in Childs Hill
- Attenuators
- Vertical risers
- Multi-storey ducts
- Horizontal duct runs
- Bends and junctions
- Access panels
Landlords, agents and facilities managers
Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and photos, so records stay tidy.
What happens if it’s left?
BESA guidance says grease shouldn’t exceed a mean of 200 microns between cleans. A reading of 500 microns or more at any point means a spot clean straight away. Putting off the clean only pushes readings higher. In Childs Hill, as across London, ductwork often passes through shared risers and other people’s space.
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.
