Kitchen duct cleaning in Northwood
The ducts are where most of the grease hides. We reach horizontal runs and vertical risers through access panels, scraping heavy deposits by hand before degreasing. Anything out of reach is noted in the report, and new panels can be fitted. If you have an extract that no longer clears the smoke and heavy grease build-up inside the duct runs, we can help, from horizontal duct runs, canopies and hoods and discharge points onwards. Extraction cleaning, hood cleaning and TR19 duct cleaning all end up in the same place: a system that is clean inside, not just on the surface, and a certificate that proves it.
Grease that collects out of sight, behind the filters and along the duct, is what insurers and fire officers worry about, so that is where most of the work in Northwood goes.
London kitchens tend to trade late and open early, so extract cleaning in Northwood is normally done overnight, after the last service. Before the clean, we agree loading, parking and roof access with whoever manages the building.
Nothing is signed off by word of mouth: a written report, dated and illustrated with pictures, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

How we price kitchen extract cleaning
The survey tells us what the work involves. The main factors are:
- Travel, parking and unloading
- Site rules, permits and inductions
- The condition we find in the survey
- Access, including roofs, risers and ceiling voids
Combining work into one visit or one programme can make for a more efficient booking. Mention every system or site you need covered, and you’ll get one fixed quote.
What we need to know
What to send for a quote:
- A few general shots of the system
- Detail shots of panels, filters and grilles
- The postcode and the type of business
- Your last certificate, test record or report
Quoting starts with a diagnosis, from your pictures and details or, where that isn’t enough, a survey on site. Then we send a fixed price so you know the cost before we start.
Northwood questions
Can parking be tricky for a job in Northwood?
Tell us where a van can stop near your site in Northwood, and about any building rules on loading. If the building has a loading slot system, we will book into it.
Which fire authority looks after Northwood?
That’s 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.
When do you clean the extract?
The clean is done when the kitchen is not cooking, so evenings, overnight, early mornings and weekends are all options. We need the equipment switched off and cooled first.
How far ahead should we book?
Earlier is better, particularly for night and weekend visits. Quotes usually come back within one working day, and there’s a 24/7 line for emergencies.
What about areas you can’t get to?
We record them on the report, with pictures where possible, and we explain what access is needed, for example new access panels.
Can you look after several sites?
Yes. One number covers all your sites across London and the South East, and visits can be set on a regular cycle.
How often should a kitchen extract be cleaned?
That comes down mainly to daily cooking hours. Heavy use of 12 to 16 hours a day calls for a clean at least every 3 months under BESA guidance, and lighter use less often. We’ll recommend a date after measuring the grease.
Is a quote from pictures possible?
Yes, for many jobs. Send a few wide photos plus close-ups of panels, filters or grilles, and a fixed quote normally follows within one working day. If pictures are not enough, we will survey first.
What we do, step by step
Each visit runs to the same pattern: sheeting and protection first, make the system safe, carry out the kitchen extract cleaning, clear away and hand over the paperwork. The visit itself takes as long as the system needs, from a few hours to several planned visits. Most London sites can’t stop for the day, so work in Northwood is normally done overnight, early in the morning or at weekends.
- Diagnosis comes first, with a survey of the system and how it’s reached.
- Grease readings set the baseline, and a fixed quote follows.
- After the kitchen closes, we sheet the area and set up to contain grease and water.
- Heavy deposits are scraped by hand and the system degreased to TR19® Grease.
- Then the clean bill of health: readings, a TR19 certificate and a photo report with the next date.
How to prepare
- Mention any parking or loading restrictions
- Have your last certificate or report to hand
- Let us know when the site is closed or quiet

Grease, kitchens and Northwood
Look up Northwood on the FSA’s food hygiene register and you will find about 51 restaurants, cafés and works canteens and about 26 takeaways in Northwood and the streets around it, up to about 1.5 miles out. Those that fry, grill or roast under a canopy need their extracts cleaned at intervals set by how long they cook. London jobs normally start after the last service, with loading and roof access agreed with the building first. The fire and rescue service for Northwood is London Fire Brigade. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
Term dates shape school work: for a school like Frithwood Primary School, an extract clean fits neatly into a half-term or summer break. Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Northwood and Pinner Cottage Hospital is the nearest hospital to Northwood, about 1 mile south.

Aftercare tips
Results last longer with the right care. We suggest:
- Keep the cleaning records where you can find them
- Flag any change in how the extract sounds or works
- Refit filters properly after cleaning
- Do not let the canopy gutters overflow
You get a photo report after every clean. It shows the system before and after, part by part, alongside a list of what was cleaned, anything out of reach and the recommended next clean date.
Run the extract whenever the kitchen is cooking. Cooking with the extract off lets grease and heat settle in the canopy, and the next clean has more to do.

Signs you need kitchen extract cleaning in Northwood
The type of cooking changes the amount of grease. Fryers, grills and open flames throw much more fat into the extract than gentler cooking, which is why grease readings matter more than the calendar.
Signs it’s time to call us include:
- Cleaning needed before an insurance renewal or survey
- Stale cooking odours from the system
- A new tenancy or takeover with no cleaning history
- An overdue clean flagged by an EHO or fire officer
If your kitchen is in a listed or historic building, like the houses around Northwood (Headstone Manor is about 3.3 miles south-east), fitting access panels needs care.

- Whether the figure could change on the day
When something else is needed
We will not sell you work that doesn’t address the problem, so here are the limits:
- A grease trap that needs emptying
- Extraction that cannot cope with the cooking because of its design
- Faulty fire dampers in the duct

Parts of the system we cover
- Plenums and filters

- Horizontal duct runs
- Discharge points
- Canopies and hoods
Different parts, different methods
Grease filters
Gaps around filters let fat through to the duct. Each filter is checked as it goes back in, and flag any that don’t.
Schools, hospitals and care homes
School, hospital and care home kitchens often have fixed hours and long holidays, so cleans can be booked when the kitchen is closed. The certificate and report suit estates and compliance files.
