Your questions about grease filter exchange in Hazel Street
Will you come out to Hazel Street?
Yes. Villages and rural sites across the South East are part of our work, Hazel Street included. Just mention lanes, gates or anything else about the site when you book.
Who inspects food businesses in Hazel Street?
Kitchens in Hazel Street are inspected by Tunbridge Wells council’s environmental health officers. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Do you provide a certificate or report?
Yes. It’s the record insurers and inspectors ask to see: a written, dated record with pictures of what we did and anything we couldn’t access.
Is there a survey before the work?
Yes. For many sites, pictures and a few details are enough, and larger or hidden systems get a visit.
Can damaged filters stay in the canopy?
A badly damaged filter should be replaced. We’ll show you which ones on the visit.
Are you insured?
Yes. Duct Doctor is fully insured, and the details are available on request.
Can you come out in an emergency?
Yes. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line, and we will advise on what to do next.
Can you give a price for filter changes?
Filters, canopies and how often you need visits all affect the price. Send us details or photos and we will quote, normally within one working day.
Grease filter exchange in Hazel Street, done properly
An exchange visit in Hazel Street doesn’t take long. The greasy filters come out, clean ones go in, and we check they’re seated with no gaps. If something looks wrong, we tell you. If you have drips falling from the filters onto equipment and missing filters in the filter bank, we can help, from school and hospital kitchens, baffle filters and wall canopies onwards.
Somewhere as small as Hazel Street, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Every one of them still needs its extract kept clear of grease, whatever the size of the place.
Accreditations are easy to claim and worth checking. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

When to call us in Hazel Street
Every fry, grill and sauté sends grease-laden vapour upwards. Much of it is trapped by the filters so they gradually clog until the air can barely get through.
If you notice any of these, it’s worth a diagnosis:
- Blocked baffle filters
- Filter washing that keeps being missed
- Grease dripping from the canopy
- Missing filters in the filter bank
If you run catering at a historic house or estate in the area (Scotney Castle is about 2.7 miles south), event kitchens in older buildings often have awkward duct runs that need planning.
Questions to ask before you book
- Whether they recommend a next date
- If the quote is a fixed price or an estimate
- How areas they cannot reach will be recorded
- Whether a survey comes first
Why deal with it now?
Grease-loaded filters are a fire risk in their own right. A flare-up on the range can reach them, and from there into the duct. Keeping filters clean takes some of that fuel away. In a place like Hazel Street, ductwork and fans are easy to forget until something goes wrong.
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account and give you a fixed price before we start.

What grease filter exchange looks like in Hazel Street
Look up Hazel Street on the FSA’s food hygiene register and you’ll find about 3 cafés, restaurants and staff canteens in Hazel Street 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. Environmental health officers from Tunbridge Wells council inspect food businesses in Hazel Street. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Keeping each certificate and photo report on file helps show the extract is looked after. Fire safety in Hazel Street falls to Kent Fire and Rescue Service. 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 Horsmonden Primary School, an extract clean fits neatly into a half-term or summer break. A hospital like Tunbridge Wells Hospital, about 5.1 miles west, is the kind of site where a kitchen may cook for patients, staff and visitors all day.
Hazel Street is about 7 miles east of Royal Tunbridge Wells, in Kent. We provide grease filter exchange for commercial premises of every kind in Hazel Street and the rest of Kent. Our Kent coverage runs to 922 places, Hazel Street among them. You can also see our page for Maidstone, about 10 miles away.
Our technicians cover all of the TN12 postcode area for grease filter exchange and the streets around it.

Near you in Hazel Street
Locally, jobs take us to businesses close to The Gun And Spitroast Public House And Rear Courtyard, among other places. The nearest railway station is Paddock Wood station, roughly 3.9 miles north. Other landmarks nearby include Old Scotney Castle (2.7 miles south) and Tunbridge Wells Hospital (5.1 miles west). Not far away are Bewl Water.
Staff cleaning versus specialist work
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.
What affects the cost of grease filter exchange
A fixed price needs a few facts first. We look at:
- Whether we need access equipment or extra panels
- The times the site is available
- How many systems or sites are involved
- How big the system is
What you pay reflects the actual work. That is why we survey first, from pictures or on site, and the price is agreed before any work starts.
Helping us quote
We can often survey from photos. Try to include:
- Close-ups of filters, grilles, hatches or access panels
- When the site is open and when it’s quiet
- The paperwork from the last visit, if you have it
- A few general shots of the system
We do not publish a price list, because every site is different. Instead, we look at your site first, from pictures or a survey, and then give you a fixed quote. To get going, call 0345 646 2711, or email photos.
Honest limits
A few issues sit outside what this work can do:
- A canopy too small for the cooking beneath it
- Grease already built up in the ductwork, which needs a full TR19 clean
- Odours from the discharge that filters will not stop
If you are not sure, just ring 0345 646 2711 or email us and we will give you a straight answer.
Parts of the system we cover
- School and hospital kitchens
- Wall canopies
- Restaurants and pubs
- Island canopies
- Mesh filters
- Baffle filters
How the visit works
Your staff don’t need to do much on the day. A contact on site lets us in at the agreed time and points us to the system, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. Photos of the system and how to reach it help us plan a visit to Hazel Street.
- We record the number, size and type of your filters.
- An exchange schedule is agreed to suit your cooking.
- The dirty set is lifted out.
- Clean filters go in and we check they sit snugly.
- The dirty filters leave with us and the next visit is booked.
Before we arrive
- Make sure someone can let us in and lock up afterwards
- Tell us the best time to work, such as after service or at a weekend
- Mention any parking or loading restrictions
How to get a quote
Quotes are quick. Call or email with a few details and you will usually have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.

Keeping the system healthy
Results last longer with the right care. We suggest:
- Clear anything stored on or near the canopy
- Do not refit a filter that’s bent
- Make sure no filter is left out
- Tell us if the menu or opening hours change
There’s no waiting: the canopy is ready as soon as the clean set is fitted. We take the greasy filters with us to be cleaned.
Damaged filters leave gaps in the defence. Sorting them now keeps grease where it can be caught.
