Grease filter exchange for kitchens and businesses in Woodhall Farm

Grease filters are the first line of defence in a kitchen extract. Their job is to stop grease getting further into the system, but only while they’re reasonably clean. Our grease filter exchange service swaps dirty filters for clean ones on a schedule. If you have filters left unwashed on busy weeks and bent or damaged filters that don’t sit properly, we can put it right, from baffle filters, restaurants and pubs and wall canopies onwards.

For a smaller kitchen near Woodhall Farm, a TR19® clean is the same job as anywhere: canopy, filters, plenum, duct, fan and discharge. We plan the visit around your hours, with the journey sorted in advance.

A written report with photos follows each visit, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

What a clean will not put right

We’d rather tell you now than book work that won’t help, so these are the things it won’t cover:

  • Cooking smells reaching neighbours, which need odour control
  • An extract that was undersized from the start
  • Extraction problems caused by the fan rather than the filters

If in doubt, phone us on 0345 646 2711 or email us and we’ll say what we think.

Kitchen extracts in Woodhall Farm

According to Food Standards Agency records, there are about 42 pubs and bars and about 4 hotels and B&Bs in Woodhall Farm and the streets around it, up to about 1.5 miles out. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Fire safety in Woodhall Farm falls to Hertfordshire Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. Environmental health officers from Dacorum council inspect food businesses in Woodhall Farm. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Before-and-after pictures from each clean are a simple way to show the extract is in hand.

Term dates shape school work: for a school like South Hill Primary School, an extract clean fits neatly into a half-term or summer break. Where a hall near Alexandra Road Congregational Church, or anywhere in Woodhall Farm, hosts lunch clubs or events, its extract gathers grease just as a café’s does. Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (High Elms Manor is about 4.8 miles south-east), access may need planning.

What affects the quote in Woodhall Farm

The survey tells us what the work involves. The main factors are:

  • How many systems or sites are involved
  • How easy every part is to reach
  • Working hours and out-of-hours timing
  • What state the system is in

Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll explain each part.

Asking for a quote

To help us quote quickly, please include:

  • Where the site is and what kind of site it is
  • Anything you’ve noticed, such as smells, noise, drips or poor airflow
  • The times we could work without disrupting the site
  • Wide photos of the system and the area around it

To get a fixed quote, give us a ring on 0345 646 2711 or send us an email with the site type, your trading hours and a short description of the system. A few pictures and your last certificate or report help a lot. We typically come back within one working day.

What staff can safely do

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.

Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.

Landlords, agents and facilities managers

We also work for facilities teams across offices, schools and healthcare across Hertfordshire. Work can be phased by floor, building or site to keep disruption down.

From a single site to a large estate, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with pictures.

Looking after it afterwards

Results last longer with the right care. Here’s what we suggest:

  • Make sure we can reach the canopy on exchange day
  • Do not let the full clean slip because filters are changed
  • Report damaged filters so they can be replaced
  • Report a dripping canopy early

Your next visit is scheduled before we leave. If cooking increases, we can change filters more often to keep up.

Filter exchange and TR19 cleaning work best together. A maintenance plan that covers both means neither slips.

Woodhall Farm: your questions answered

Who enforces fire safety at workplaces in Woodhall Farm?

Woodhall Farm is in the area of Hertfordshire Fire and Rescue Service. TR19® is not law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.

Who would carry out a food hygiene inspection at a kitchen in Woodhall Farm?

That’s Dacorum council, whose environmental health officers carry out food hygiene inspections in Woodhall Farm. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.

What does grease filter exchange cost?

Every kitchen is different, so we quote once we know your filters and schedule. You get a fixed price before the service starts.

What if some of our filters are damaged?

A bent filter leaves a gap for grease. We point them out on the visit and explain what’s needed.

Can you look after several sites?

Yes. Tell us the addresses and what each needs and you’ll get one fixed quote.

How long does the visit take?

On site, it takes less than an hour in most kitchens. Larger systems naturally take longer, and the quote will say how long.

How regularly do grease filters need exchanging?

There’s no single answer. We look at your cooking and set an interval to match, and adjust it if needed.

What types of filter do you exchange?

Baffle filters and mesh filters. Tell us what you have when you ring 0345 646 2711 or email us and we will confirm it on site.

Why deal with it now?

In Woodhall Farm, as everywhere, a filter service is not a substitute for TR19 cleaning. But clean filters do help the system between cleans, and that shows when the next clean comes round. Systems on quieter sites still build up dirt and wear, just more slowly.

No two sites are the same, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.

The process

Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. All told, the work takes well under an hour for most canopies. For a site near Woodhall Farm, the work is booked around your opening hours, evenings and weekends included.

  1. We look at the canopies and the condition of the filters.
  2. We note any filters that are bent, damaged or missing.
  3. We exchange the dirty filters for a clean set.
  4. The filters are checked for fit before we go.
  5. Anything that needs attention, such as a greasy plenum, is pointed out.

Before we arrive

  • Find the previous report, if there is one
  • Agree a time when the area can be out of use
  • Let us know how we reach the system, including roofs, risers and plant rooms

Ask for a quote

Every quote begins with a look at the system, from your photos and details or, where that is not enough, a survey on site. Then we send a fixed price, before any work starts.
