Grease filter exchange in Dagnall

How the visit works

There’s very little for your team to do 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. Before we leave, the area is tidied and the paperwork follows. For a village or hamlet like Dagnall, tell us about narrow lanes, gates and parking when you book.

  1. We record the number, size and type of your filters.
  2. We set the interval with you.
  3. On each visit, we remove the greasy filters.
  4. A clean set is fitted and checked for gaps.
  5. The dirty filters leave with us and the next visit is booked.

Before we arrive

  • Let us know how we reach the system, including roofs, risers and plant rooms
  • Tell us where we can park and unload
  • Mention any sign-in, permit or induction we need

How we handle grease filter exchange in Dagnall

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. Typical jobs include weak extraction at the canopy and filters that leave gaps in the canopy, across baffle filters, mesh filters and island canopies.

In a village or hamlet like Dagnall, the kitchens that need extract cleaning are normally 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, whatever the size of the place.

We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

When it’s something else

Grease filter exchange cannot fix everything, and we will tell you before we start. It won’t put right:

  • Grease deep in the extract system
  • Odours from the discharge that filters won’t stop
  • An extract that was undersized from the start

If you’re not sure, just ring 0345 646 2711 or drop us a line and we will give you a straight answer.

What the work covers

  • Mesh filters
  • Wall canopies
  • Island canopies
  • Restaurants and pubs
  • Baffle filters
  • School and hospital kitchens

Landlords, agents and facilities managers

Managing agents often deal with us directly. Tell us the site, the work and the access arrangements and we will come back with a fixed quote.

Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.

How we price grease filter exchange

Before we fix a price, we need to know a few things. We check:

  • The condition we find in the survey
  • Parking and loading at the site
  • Working hours and out-of-hours timing
  • The size of the system

The price reflects the work, not guesswork. That is why every job is surveyed first, and why the quote is fixed before we start.

Asking for a quote

You don’t need the technical terms. It helps if you can send:

  • Any access panels or hatches you can see
  • Wide photos of the system and the area around it
  • Your opening hours and when the area is out of use
  • Any previous report or certificate

We don’t publish a price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To start, call us on 0345 646 2711, or send details by email.

How the job changes from site to site

Mesh filters

Mesh filters use layers of metal mesh to trap grease. In a busy kitchen, mesh soon blocks and need frequent attention.

Baffle filters

In a baffle filter, the air zigzags through metal baffles. Grease drops out as it does.

Kitchen extracts in Dagnall

The FSA’s food hygiene register includes about 3 pubs, bars and clubs within 1.5 miles or so of the middle of Dagnall. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. It’s Buckinghamshire council that sends environmental health officers to food businesses in Dagnall. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A dated certificate in the maintenance file answers the question before it’s asked. The fire and rescue service for Dagnall is Hertfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.

Church and community hall kitchens, near Church of All Saints or anywhere around Dagnall, are easy to forget, but their extracts collect grease like any other. Healthcare kitchens, like those at hospitals such as Luton and Dunstable Hospital (about 5.3 miles north-east), often cook for long hours, which puts them in BESA’s heavier-use bands. School kitchens, at schools like Dagnall VA Church of England School for example, are typically cleaned in the holidays so no lunches are lost.

Keeping the system healthy

No system stays clean for ever, but care slows the build-up. A few tips:

  • Tell us if a filter is bent or damaged
  • Let us know if your cooking hours increase
  • Always run the extract while cooking
  • Never leave gaps in the filter bank

If the plenum behind the filters looks greasy, we say so. That might mean bringing a TR19® clean forward, and we can arrange it.

Bent or missing filters let grease straight past. Replacing them early protects the plenum and ductwork.

In-house cleaning or a specialist?

Staff cleaning and specialist work aren’t the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.

When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We’ll take a look and give you a fixed quote.

How do you protect the area?

With sheeting and covers, before anything else happens. We keep the work contained and leave the area clean.

How far ahead should we book?

Earlier is better, especially for out-of-hours work. Quotes normally come back within one working day, and there’s a 24/7 line for emergencies.

What about areas you can’t get to?

They’re listed in the report, never skipped quietly. The report says which parts couldn’t be reached and why, along with a quote to put access in.

Can you set up regular visits?

Yes. Regular plans can run on 3, 6 or 12-monthly cycles, to suit the system and how it’s used.

Do you take the used filters away?

The greasy set leaves with us for cleaning and your staff don’t have to deal with them. Clean filters go straight in.

What happens to the waste?

We contain it and take it with us. We collect grease, debris and waste water as we go rather than letting it spread.
