How we price grease filter exchange
Every site gets its own quote. These are the things that affect it:
- A single visit or a regular plan
- Access, including roofs, risers and ceiling voids
- Where the site is and how we reach it
- The condition we find in the survey
The price reflects the work, not guesswork. That’s why we survey first, from pictures or on site, and why the quote is fixed before work begins.
Asking for a quote
Photos and a few facts are often enough to price the work. Useful things to send:
- When the site is open and when it’s quiet
- Photos showing the whole system and its surroundings
- The roof, plant room or outside wall the system runs to
- Any previous report or certificate
For grease filter exchange in Grahame Park, call 0345 646 2711, or send details by email. Tell us what kind of premises it is and when it’s open, plus pictures or the previous report if they’re to hand. We normally send a fixed quote within one working day.
How we handle grease filter exchange in Grahame Park
Good filters only work when they fit properly. Gaps in the filter bank are a direct route into the plenum and every filter is checked when we swap them. Damaged filters are flagged so they can be replaced. Common call-outs are for blocked baffle filters and grease dripping from the canopy, on mesh filters, island canopies and wall canopies.
London kitchens tend to trade late and open early, so extract cleaning in Grahame Park is normally done overnight, after the last service. Parking, loading and access to the roof are agreed with the building before the night of the clean.
Duct Doctor has been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.

Grahame Park questions
Who inspects food businesses in Grahame Park?
Kitchens in Grahame Park are inspected by Barnet council’s environmental health officers. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Can school kitchens in Grahame Park be cleaned in the holidays?
Yes, and it’s the easiest time to do it. Food Standards Agency records list about 44 schools, colleges and universities with registered kitchens within about a mile and a half of Grahame Park. You can give us a ring on 0345 646 2711 or send us an email with the dates the site is empty.
Can you give a price for filter changes?
Every kitchen is different, so we need to know the filters and interval first. You get a fixed price before the first visit.
Which accreditations do you hold?
Our accreditations are CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
What types of filter do you exchange?
The common types of grease filter: baffle and mesh. Tell us what you have when you ring 0345 646 2711 or send us an email and we’ll confirm it on site.
Do you look at the system first?
Yes. We always survey first, either from pictures and details you send or on a site visit. Then you get a fixed quote.
Can damaged filters stay in the canopy?
Damaged filters do not seat properly and let grease through. We point them out on the visit so they can be replaced.
Are you fully insured?
Yes. We carry full insurance and have been trading since 2009.
Staff cleaning versus specialist work
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
How the job changes from site to site
The plenum
A greasy plenum is a sign filters have been left too long, or that a full clean is due.
Canopy filter housings
We check that filters sit snugly in the housing at each visit since a gap is a route for grease.
Grahame Park kitchens: local notes
The Food Standards Agency lists about 26 bars, pubs and nightclubs as registered food businesses in and around Grahame Park, up to about a mile and a half out. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Overnight is the normal time to clean a London kitchen extract, so trading isn’t affected. The fire and rescue service for Grahame Park is London Fire Brigade. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
For schools such as St James' Catholic High School, kitchen extract cleaning is normally booked for the holidays, when the canteen is closed. Commuter trade near Mill Hill Broadway station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands. Church and community hall kitchens, near St Augustine Grahame Park or anywhere around Grahame Park, are easy to forget, but their extracts collect grease like any other.

When it’s something else

- Grease behind the filters that a swap cannot remove
- A noisy or failed extract fan

How the visit works
Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. All told, the work takes anything from a few minutes to an hour or so, depending on the number of filters. For a job in Grahame Park, tell us about loading bays, permits, lifts and roof access when you book.
- We record the number, size and type of your filters.
- An exchange schedule is agreed to suit your cooking.
- On each visit, we remove the greasy filters.
- A clean set is fitted and checked for gaps.
- The dirty filters leave with us and the next visit is booked.
Before we arrive
- Mention any sign-in, permit or induction we need
- Make sure someone can let us in and lock up afterwards
- Clear the space around the work
Ask for a quote
Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
Related advice
What happens if it’s left?
A filter exchange is a few minutes; a choked extract affects a whole service. Few maintenance jobs are as easy and few are as easy to forget. For a site in Grahame Park, fitting the work in overnight now is far easier than closing at short notice later.
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, which can make the next visit longer. If you’re not sure what’s needed, give us a ring on 0345 646 2711 or drop us a line for straight advice and a fixed quote.

Aftercare tips
To keep the system working properly between visits:
- Mention it if the kitchen gets busier
- Keep the extract on whenever the range is in use
- Look out for drips from the canopy
- Never leave gaps in the filter bank
We tell you if we spot anything in the canopy that needs attention. It can be a sign that a full TR19® clean is due and we can book that in.
Filters that are left too long stop protecting the system. A regular cycle keeps the rest of the system cleaner between full cleans.
