How we handle grease filter exchange in South Harefield
Grease filters are the first line of defence in a kitchen extract. Their job is to stop grease getting further into the system and they do it best when they’re clean. Our grease filter exchange service swaps dirty filters for clean ones on a schedule. Typical jobs include grease building up behind the canopy filters and filters so greasy the air can barely pass, across wall canopies, school and hospital kitchens and restaurants and pubs.
Work in a small place like South Harefield starts with a call to agree access and timings, and the clean covers the whole system, as it would anywhere: canopy to discharge, then a TR19® certificate and a photo report.
A written report with pictures follows each visit, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Leave it or put it right?
When filters block, extraction suffers. The kitchen gets hotter and smokier while the fan strains. Keeping filters clean keeps the extract working properly. With notice, the visit to South Harefield can be fitted around your bookings and events.
No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.

What we’re called out for in South Harefield
Washing filters by hand doesn’t always get them clean. Grease lodges deep in baffles and mesh and a sink wash rarely reaches it.
It’s time to book a visit if you see:
- Grease filters clogged with grease
- Hand-washed filters that still look greasy
- A canopy running with filters missing
- Bent or damaged filters that don’t sit properly
School kitchens, at schools like Harefield Infant School for example, are usually cleaned in the holidays so no lunches are lost.
Questions to ask before you book
- Whether the quote shows VAT
- What records you will receive afterwards
- Whether a survey comes first
- Whether the price is fixed
South Harefield kitchens: local notes
According to Food Standards Agency records, there are about 11 pubs, bars and clubs within roughly a mile and a half of the centre of South Harefield. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. South Harefield sits within the area of Buckinghamshire Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel. It’s Hillingdon council that sends environmental health officers to food businesses in South Harefield. 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.
Where a hall near Church of St Mary the Virgin, or anywhere in South Harefield, hosts lunch clubs or events, its extract gathers grease just as a café’s does. If you run catering at a historic house or estate in the area (Ickenham Hall is about 2.7 miles south-east), event kitchens in older buildings often have awkward duct runs that need planning.

How the visit works
The first job on site is protection: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins.

- We look at the canopies and the condition of the filters.
- We note any filters that are bent, damaged or missing.
- We exchange the dirty filters for a clean set.
- We check the filters are seated and the canopy is ready to use.

Related advice
What staff can safely do
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.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
Looking after it afterwards
Simple habits between visits make a real difference. We recommend:
- Watch for grease drips between visits
- Never cook with the extract switched off
- Do not let the full clean slip because filters are changed
- Keep canopy surfaces wiped down
Nothing changes for your staff, except one less greasy job. Make sure we can reach the canopy on exchange day and tell us if service times change.
Saturated filters let more grease through. A regular cycle keeps the rest of the system cleaner between full cleans.
Landlords, agents and facilities managers
Whether it’s one building or many, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with pictures.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
When something else is needed
To be straight with you, some problems need a different fix:
- A canopy too small for the cooking beneath it
- A noisy or failed extract fan
- Grease behind the filters that a swap cannot remove
If in doubt, call 0345 646 2711 or send us an email and we’ll say what we think.

South Harefield questions
Can a school canteen extract in South Harefield be done out of term time?
Yes. The holidays are the usual time for school work. There are about 4 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of South Harefield. Tell us your holiday dates and we will book the visit for when the site is empty.
Do you work overnight in South Harefield?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in South Harefield needn’t be disturbed. Tell us your opening hours when you ask for a quote.
Are you insured?
Yes, fully. CHAS and SafeContractor accreditation sit alongside it, for sites that check contractor safety.
What’s the right interval for changing filters?
That depends on the cooking. Kitchens that fry and grill all day need changes more often than lighter ones. We set a schedule that suits your kitchen.
What happens to the dirty filters?
We take them away to be cleaned, so your staff don’t have to wash them. A clean set is fitted in their place.
Is TR19 a legal requirement?
No. The law sets the duty, and TR19® is the recognised benchmark for meeting it. Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person has to manage fire risk, and without records, many insurers may refuse or reduce a claim.
Do you work with multi-site operators?
Yes. Our area covers London and the South East, so we can schedule a run of sites on one programme. Every site has its own report.
Which kinds of sites do you work on?
Commercial premises of every kind: kitchens, offices, schools, healthcare, retail, leisure and food production. Work is timed around how each site runs.
