How we price grease filter exchange
Some jobs are bigger than they look, and some smaller. The main factors:
- Access, including roofs, risers and ceiling voids
- Travel, parking and unloading
- The condition we find in the survey
- A single visit or a regular plan
Working hours, access and the scale of the site all affect the cost. We take each of them into account, and the price is fixed before work begins.
What we need to know
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- Your last certificate, test record or report
- Your opening hours and when the area is out of use
- The roof, plant room or outside wall the system runs to
- Close-ups of filters, grilles, hatches or access panels

About our grease filter exchange in Bush Hill
In Bush Hill, our filter exchange runs on a schedule set by how much the kitchen cooks. Busy kitchens need changes more often while a lighter kitchen can go longer. We agree the interval with you at the start. We are often asked to deal with grease collecting in the filter channels and smoke and heat lingering under the hood, across school and hospital kitchens, mesh filters and island canopies.
In London, few kitchens can spare a day to close, so work in Bush Hill is normally booked for the night or the early hours. Before the clean, we agree loading, parking and roof access with whoever manages the building.
Good records are part of the job. You get a written report with pictures after every visit, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

Questions from Bush Hill
Can parking be tricky for a job in Bush Hill?
A loading bay, a visitor permit or off-street space near the site in Bush Hill makes the visit easier to plan. If the building has a loading slot system, we will book into it.
Which council inspects kitchens in Bush Hill?
Food hygiene inspections in Bush Hill are carried out by Enfield council. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
What accreditations do you have?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.
Can you come out in an emergency?
Yes. There’s a 24/7 emergency line for anything that can’t wait until a planned visit. Ring any time and tell us what’s happened.
Do you clean filters as well as exchanging them?
Yes, filters can be cleaned on a schedule as well as exchanged. We’ll talk you through which suits your kitchen when we quote.
What happens to the waste?
It’s contained and taken away. Grease, debris and waste water are collected as the work goes on rather than letting it spread.
Can we book visits on a schedule?
Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. Each report recommends when the next visit should be.
Is there a survey before the work?
Yes. Photos often do the job, and larger or hidden systems get a visit.
When to call us in Bush Hill
Filters get bent and damaged with handling. Damaged filters do not sit flush, leaving gaps for grease to slip through.
Common reasons sites call us include:
- A canopy running with filters missing
- Staff short of time to wash filters
- Poor airflow through the filters
- Grease collecting in the filter channels
Commuter trade near Grange Park station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands.
What to look for in a quote
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- What hours they’ll be on site
- Whether the whole system is included, or only the parts that are easy to reach
- Whether they recommend a next date
The process
Protection comes first: floors, worktops and anything near the work are covered. Then we make the system safe and start. The work on site takes anything from a few minutes to an hour or so, depending on the number of filters, and we clear up before we go. In Bush Hill, as across London, we normally work overnight or at weekends and hand the site back ready to open.
- We start by noting how many filters you have and what type they are.
- Together we set how often the filters should be changed.
- Each visit starts with the used filters being removed.
- We fit clean filters and check they sit snugly in the housing.
- Anything we notice, such as bent filters or a dirty plenum, is pointed out.
Preparing for the visit
- Arrange a key holder or contact on site
- Have your last certificate or report to hand
- Tell us the best time to work, such as after service or at a weekend
Getting a quote
Quotes are quick. Send a few details and photos, and we typically reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.

Why act early in Bush Hill
Grease dripping from the canopy is a sign the filters can’t hold any more. Left, it ends up on equipment, food areas and staff and that is the kind of thing inspectors look for. In Bush Hill, a planned overnight visit is much easier than closing unexpectedly.
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.
Why us?
- Trading since 2009
- Work around your opening hours, with 24/7 emergency cover
- Every job surveyed first
- Fixed quotes from a survey or pictures

Looking after it afterwards
After the visit, a few habits help the work last:
- Keep every filter in place during service
- Report a dripping canopy early
- Keep the canopy clear for exchange visits
- Let us know if your cooking hours increase
Your team carries on as normal, without the filter washing. Make sure we can reach the canopy on exchange day and let us know of any changes to opening hours.
If filters are already dripping, they’re overdue. Changing them now reduces the fuel above the cooking and the plenum may need a clean as well.
When it’s something else
An honest diagnosis matters more to us than a booking, so here’s what grease filter exchange will not do:
- A fan that’s failing or too weak for the system
- A canopy that needs a proper clean
- An extract that was undersized from the start
Not sure which it is? You can call 0345 646 2711, or email photos and we will tell you honestly.
What the work covers
- Mesh filters
- Baffle filters
- Restaurants and pubs
- School and hospital kitchens
- Wall canopies
- Island canopies
How the job changes from site to site
Mesh filters
Older or smaller canopies often use mesh filters. They can be on the same exchange schedule as baffle filters.
The plenum
Clean filters reduce the grease reaching the plenum, but it still needs cleaning as part of TR19.
Kitchen extracts in Bush Hill
Food Standards Agency data counts about 168 restaurants, cafés and works canteens and about 79 takeaways and sandwich shops in Bush Hill and the streets around it, up to about 1.5 miles out. Each canopy among them has filters that load with grease and need swapping or cleaning. Most London extract cleaning happens at night, after the last service. Food hygiene inspections in Bush Hill are the job of Enfield council’s environmental health team. Extraction counts as kitchen equipment, so its condition can come up on the day. Our report lists what was cleaned and when, which is useful to have ready.
For schools such as Grange Park Preparatory School, kitchen extract cleaning is normally booked for the holidays, when the canteen is closed. A hospital like St Michaels Hospital, about 1.4 miles north, is the kind of site where a kitchen may cook for patients, staff and visitors all day.
