How we handle grease filter exchange in Porter's End
Good filters only work when they fit properly. Bent, damaged or missing filters leave gaps, so we check every one at each visit. Damaged filters are flagged so they can be replaced. The work covers wall canopies, mesh filters and restaurants and pubs, and people most often call us about weak extraction at the canopy and filters that come out of the sink still dirty.
In a village or hamlet like Porter's End, the kitchens that need extract cleaning are typically a pub, a school, a care home or a hall kitchen, wherever there is one. Every one of them still needs its extract kept clear of grease.
Nothing is signed off by word of mouth: a dated report with pictures of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

Your questions about grease filter exchange in Porter's End
Which fire service covers Porter's End?
That is Hertfordshire Fire and Rescue Service. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Who would carry out a food hygiene inspection at a kitchen in Porter's End?
That is North Hertfordshire council, whose environmental health officers carry out food hygiene inspections in Porter's End. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.

Yes. Our area covers London and the South East, so sites at different addresses can be planned together as one programme. Each site gets its own report and photos.

Yes, always. We diagnose before we treat: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
Is there a cleaning option for the filters we have?
We offer filter cleaning as well as exchange. We will talk you through which suits your kitchen when we quote.
Are you fully insured?
Yes, we’re fully insured. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.

Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line, and we’ll advise on what to do next.

For landlords and multi-site operators
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements and we’ll come back with a fixed quote.
Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.
How it 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. The work on site takes a short visit, depending on how many filters the canopies hold, and we clear up before we go. We agree a date with you, plan the drive to Porter's End and turn up when the site is quiet.
- We count and measure the filters in every canopy.
- Together we set how often the filters should be changed.
- At every visit, the greasy filters are lifted out.
- Clean filters go straight back in, seated properly with no gaps.
- Anything we notice, such as bent filters or a dirty plenum, is pointed out.
How to prepare
- Tell us where we can park and unload
- Let us know about permits to work or site inductions
- Make sure someone can let us in and lock up afterwards
Ask for a quote
There’s no standard price list, because every site is different. Instead, we look at your site first, from pictures or a survey, and then send you a fixed quote. To get going, call 0345 646 2711 or use the quote form.
Advice
In-house cleaning or a specialist?
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Leave it or put it right?
Washing filters in-house is an option for kitchens in Porter's End, and that can work if it’s done thoroughly and on time. When it doesn’t happen reliably, an exchange makes it automatic. A fault that closes a site in a village like Porter's End affects everyone who depends on it.
What you pay reflects the actual work. That is why every job is surveyed first, and the price is agreed before any work starts.

Aftercare tips
No system stays clean for ever, but care slows the build-up. Our tips:
- Do not refit a filter that’s bent
- Let us know if your cooking hours increase
- Wipe the outside of the canopy as part of daily cleaning
- Keep the extract on whenever the range is in use
Between visits, check that every filter is still in place. Gaps let grease into the plenum, so let us know if one goes missing or gets damaged.
Dripping filters are a clear sign they’re full. Changing them now reduces the fuel above the cooking, and it’s worth checking the plenum too.
What grease filter exchange can’t fix
Before you book, it helps to know what’s not included:
- A canopy that needs a proper clean
- Smell complaints that need odour control equipment
- A canopy too small for the cooking beneath it
If in doubt, call us on 0345 646 2711 or use the quote form and we will say what we think before you book.
