How we handle grease filter exchange in Darby Green
A clean set of filters is a simple, regular dose of prevention. Between full cleans, it keeps the airflow healthy, and it saves your staff a greasy job. The full TR19 clean then gives the system its clean bill of health. If you are dealing with grease collecting in the filter channels and filters so greasy the air can barely pass, we can put it right, from restaurants and pubs, mesh filters and island canopies onwards.
Somewhere as small as Darby Green, 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.
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 carry full insurance.

Keeping the system healthy
Think of this as the after-treatment advice, in brief:
- Keep filter exchange and TR19 cleaning on the same plan
- Never leave gaps in the filter bank
- Report a dripping canopy early
- Tell us if a filter is bent or damaged
Once the clean filters are in, the kitchen can cook straight away. The dirty set leaves with us to be cleaned.
Filters that are left too long stop protecting the system. Getting onto a regular exchange now keeps grease out of the plenum and ductwork between full cleans.
What happens on the day
Your trading hours come first. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes anything from a few minutes to an hour or so, depending on the number of filters. Rural roads and tight entrances are worth telling us about before a visit to Darby Green.
- The filters in each canopy are measured and counted.
- An exchange schedule is agreed to suit your cooking.
- The dirty set is lifted out.
- A clean set is fitted and checked for gaps.
- We take the greasy set away and confirm the next date.
How to prepare
- Allow time for equipment near the work to be turned off and cool down
- Tell us the best time to work, such as after service or at a weekend
- Mention any locked doors, roof access or ceiling voids
Ask for a quote
Photos are enough for some jobs, while others need a look on site. 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.

Landlords, agents and facilities managers
We regularly work with managing agents. Send the address, what’s needed and how access works and we’ll come back with a fixed quote.
Running several sites is easier with one contractor. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.
When something else is needed
In fairness, there are a few things this work won’t fix:
- A canopy too small for the cooking beneath it
- Extraction problems caused by the fan rather than the filters
- Grease deep in the extract system
If you are not sure, just phone us on 0345 646 2711 or drop us a line and we will give you a straight answer before you book.
Where we work
- Island canopies
- Wall canopies
- Restaurants and pubs
- School and hospital kitchens
- Baffle filters
- Mesh filters
What happens if it’s left?
Some kitchens in Darby Green wash filters themselves to save the cost of a service, and it works when it’s done well and never skipped. Where it slips, an exchange service takes the job off staff. Rural sites can’t always move to another kitchen or room when something fails.
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 explain each part.

- A fixed price before any work starts

Staff cleaning versus specialist work
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
What affects the cost of grease filter exchange
Before we fix a price, we need to know a few things. We check:
- Access, including roofs, risers and ceiling voids
- A single visit or a regular plan
- Working hours and out-of-hours timing
- What state the system is in
What you pay depends on the size of the system, the condition it’s in and how easy it is to reach. We give you a fixed price before work begins, so you know where you stand.
Helping us quote
Photos let us diagnose from a distance. The most useful are:
- A few general shots of the system
- Any access panels or hatches you can see
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Your opening hours and when the area is out of use
Quotes are quick. Call or email with a few details and you will normally have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
Grease filter exchange in Darby Green: the local picture
Food Standards Agency data counts about 33 restaurants, cafés and works canteens and about 28 sandwich bars and takeaways in and around Darby Green, up to about a mile and a half out. Each canopy among them has filters that load with grease and need swapping or cleaning. Food hygiene inspections in Darby Green are the job of Hart council’s environmental health team. 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. Darby Green sits within the area of Hampshire and Isle of Wight Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
Healthcare kitchens, like those at hospitals such as Frimley Park Hospital (about 2.9 miles east), often cook for long hours, which puts them in BESA’s heavier-use bands. Term dates shape school work: for a school like Potley Hill Primary School, an extract clean fits neatly into a half-term or summer break. Volunteers running a hall kitchen near St Barnabas Church, or anywhere in Darby Green, may not know when the extract was last cleaned, and a grease test settles it.

Darby Green: your questions answered
Do you work at weekends in Darby Green?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Darby Green needn’t be disturbed. Tell us your opening hours when you ask for a quote.
Who would carry out a food hygiene inspection at a kitchen in Darby Green?
That is Hart council, whose environmental health officers carry out food hygiene inspections in Darby Green. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Can you look after several sites?
Yes. One number covers all your sites across London and the South East, with visits on a regular schedule.
Do we need to close while you work?
Not typically. We need the work area to ourselves while we are on site, so we book a time when it would be closed anyway.
Is filter exchange enough instead of a full extract clean?
No, the two work together. A TR19® clean deals with the whole system and comes with a certificate and photo report.
Can we book visits on a schedule?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, to suit the system and how it’s used.
What does TR19 mean?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked, and it takes a risk-based approach.
Do you offer emergency callouts?
Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line, and we’ll advise on what to do next.
