Your questions about grease filter exchange in Kemprow
Who carries out food hygiene inspections in Kemprow?
That is Hertsmere council, whose environmental health officers carry out food hygiene inspections in Kemprow. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Will you come out to Kemprow?
Yes. Kemprow is within the area we cover across London and the South East. A survey first, from pictures or a visit, means we arrive with the right kit.
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 if some of our filters are damaged?
Damaged filters don’t seat properly and let grease through. We point them out on the visit so they can be replaced.
How long does grease filter exchange take?
We’ll confirm the time with your quote. For a typical site, it takes a short visit, depending on how many filters the canopies hold.
How much does a filter exchange service cost?
We price it on the number of filters and the visit frequency. Tell us what you have and we will come back with a fixed quote, usually within one working day.
What paperwork should we keep on file?
Everything that shows the system is looked after: our reports and photos, any certificates and your in-house logs. One maintenance log per site keeps it simple.

Grease filter exchange in Kemprow, done properly
Cleaning filters by hand takes staff time and is easy to put off. An exchange service means clean filters arrive and greasy ones leave and the canopy is refilled straight away. We are often asked to deal with filters that come out of the sink still dirty and drips falling from the filters onto equipment, across wall canopies, restaurants and pubs and island canopies.
Somewhere as small as Kemprow, 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.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Why act early in Kemprow
Grease-loaded filters are a fire risk in their own right. Flames from the range can be drawn up into the canopy and grease in the duct can carry a fire further. Clean filters mean less fuel in the canopy. Rural sites cannot always move to another kitchen or room when something fails.
When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote and give you a fixed price before work begins.

What grease filter exchange looks like in Kemprow
The FSA’s food hygiene register shows about 26 restaurants, cafés and works canteens and about 8 takeaways and sandwich shops in and around Kemprow, up to about a mile and a half out. Swapping filters on a schedule keeps kitchens like these drawing air properly. Kemprow sits within the area of Hertfordshire Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises. Kitchens in Kemprow get their food hygiene inspections from Hertsmere council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
For schools such as Fair Field Junior School, kitchen extract cleaning is typically booked for the holidays, when the canteen is closed. Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Shenley Hospital is the nearest hospital to Kemprow, about 2.3 miles north-east. Historic houses near Kemprow, such as High Elms Manor about 2.7 miles north-west, are a reminder that older buildings with event kitchens can have long, awkward duct routes.

Local landmarks in Kemprow
Around Kemprow, our work takes us to kitchens and buildings near Garston Park, Three Horseshoes Public House and Queens' School and the streets around them. For rail, the closest station is Radlett station, roughly 1.1 miles east of the centre. A little further out are Radlett and District Museum (1.1 miles east) and Harlequin Centre (2.9 miles south-west). For a walk, there’s Broad Colney Lakes and Verulamium Lake.
Looking after it afterwards
Here’s the after-treatment advice, short and simple:
- Keep the extract on whenever the range is in use
- Let us know if your cooking hours increase
- Keep canopy surfaces wiped down
- Watch for grease drips between visits
Between visits, check that every filter is still in place. A missing filter leaves a gap for grease, so let us know if one goes missing or gets damaged.
Filter exchange and TR19 cleaning work best together. Setting both up on a schedule means neither slips.
Staff cleaning versus specialist work
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.

Landlords, agents and facilities managers
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we’re happy to quote for all of it.
Facilities teams in offices, schools and healthcare sites book us too in Kemprow and across Hertfordshire. Work can be phased by floor, building or site to keep disruption down.
What affects the quote in Kemprow
Sites vary more than people expect. What affects the quote:
- One-off work versus a regular cycle
- How big the system is
- When the work can happen, such as evenings, overnight or weekends
- Where the site is and how we reach it
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you’re not sure what’s needed, give us a ring on 0345 646 2711 or use the quote form for straight advice and a fixed quote.
What to send for a quote
Before you ask for a quote, gather:
- The times we could work without disrupting the site
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- How we’d reach plant on a roof or in a plant room
- Any access panels or hatches you can see
Quoting starts with a diagnosis, from your pictures and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work so you know the cost before work begins.
The process
Every visit runs to the same pattern: sheeting and protection first, isolate whatever needs isolating, carry out the grease filter exchange, clear away and leave you the report. The visit itself takes well under an hour for most canopies. The timing of a visit to Kemprow is set by you, and the travel is our side of the planning.
- We start by noting how many filters you have and what type they are.
- A change schedule is agreed to match the kitchen’s cooking hours.
- Each visit starts with the used filters being removed.
- Clean, dry filters are fitted in their place, with no gaps left between them.
- Anything we notice, such as bent filters or a dirty plenum, is pointed out.
How to prepare
- Make sure someone can let us in and lock up afterwards
- Agree a time when the area can be out of use
- Tell us where we can park and unload
