Grease filter exchange near Great Offley

Aftercare tips

Here’s the after-treatment advice, short and simple:

  • Mention it if the kitchen gets busier
  • Never cook with the extract switched off
  • Report a dripping canopy early
  • Clear anything stored on or near the canopy

Your next visit is scheduled before we leave. If the kitchen gets busier, the interval can be shortened to match.

Clean filters plus regular full cleans keep the system in good health. Setting both up on a schedule keeps everything on track.

How we handle grease filter exchange in Great Offley

A clean set of filters is a simple, regular dose of prevention. It keeps airflow up and grease down between full cleans, and it saves your staff a greasy job. The full TR19 clean then gives the system its clean bill of health. If you have a canopy that drips grease and staff short of time to wash filters, we can put it right.

Somewhere as small as Great Offley, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Each still has a canopy and duct that collect grease.

It’s worth checking any contractor’s accreditations. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

What affects the quote in Great Offley

The price is fixed before any work begins. It’s based on:

  • Whether it’s a one-off visit or part of a schedule
  • How many systems or sites are involved
  • Access, including roofs, risers and ceiling voids
  • The scale of the work

One small site or a whole estate, the quote is built the same way: what needs doing, how we get to it and when. The price is fixed before work begins.

Helping us quote

You do not need the technical terms. Just send:

  • Wide pictures of the system and the area around it
  • Your opening hours and when the area is out of use
  • The postcode and the type of business
  • Any access panels or hatches you can see

The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.

What a clean will not put right

In fairness, some problems need a different fix:

  • Odours from the discharge that filters will not stop
  • A canopy too small for the cooking beneath it
  • Extraction problems caused by the fan rather than the filters

Not sure which it is? You can call 0345 646 2711, or email photos and we will tell you honestly before booking.

What the work covers

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

What we’re called out for in Great Offley

Sometimes a filter is taken out and never put back. A missing filter leaves an open route into the system where it settles out of sight.

These are the problems we see most often:

  • Drips falling from the filters onto equipment
  • Grease building up behind the canopy filters
  • Staff short of time to wash filters
  • A canopy running with filters missing

Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Keech Hospice Care is the nearest hospital to Great Offley, about 4.2 miles west.

Questions to ask before you book

  • Whether the work can be done while the site is closed
  • If they look at the system before pricing
  • Whether the whole system is included, or only the parts that are easy to reach
  • Proof of insurance

Choosing a duct cleaning contractor

Grease filter exchange in Great Offley: the local picture

Food Standards Agency records include about 4 bars, pubs and nightclubs across Great Offley and its immediate surroundings (about a mile and a half). Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. Great Offley sits within the area of Hertfordshire Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract. Kitchens in Great Offley get their food hygiene inspections from North Hertfordshire council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Keeping each certificate and photo report on file helps show the extract is looked after.

Church and community hall kitchens, near Church of St Mary Magdalene or anywhere around Great Offley, are easy to forget, but their extracts collect grease like any other. Bursars and site managers at schools such as Offley Endowed Primary School tend to book extract cleaning for when the kitchen is empty.

Questions from Great Offley

Can the work in Great Offley be done at night or at weekends?

Yes, we can come after you close and finish before you open. That way a site in Great Offley doesn’t have to lose a day’s trading. Just call us on 0345 646 2711, or send details by email with your opening times and we’ll plan around them.

Who would carry out a food hygiene inspection at a kitchen in Great Offley?

Kitchens in Great Offley are inspected by North Hertfordshire council’s environmental health officers. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.

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.

Are you insured?

Yes. Full insurance covers our work and have been trading since 2009.

What’s the right interval for changing filters?

It varies from kitchen to kitchen. We look at your cooking and set an interval to match, and adjust it if needed.

Where does the waste go?

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

Is TR19 cleaning required by law?

No. TR19® is BESA’s specification, not legislation. The law is the Regulatory Reform (Fire Safety) Order 2005, which makes the responsible person assess and reduce fire risk, and cleaning to TR19® is the recognised way to show grease is under control.

Can you look after several sites?

Yes. One number covers all your sites in our area, and visits can be set on a regular cycle.

What happens on the day

We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool first, and floors and nearby surfaces are sheeted. On site, it takes a few minutes per canopy, longer for a large kitchen with several canopies. Somewhere as small as Great Offley, the date and timings are agreed with you well before the day.

  1. First, we check the canopies and the filters in them.
  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

  • Mention any parking or loading restrictions
  • Tell us the best time to work, such as after service or at a weekend
  • Dig out any earlier paperwork for the system

Getting a quote

Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before we start.

What staff can safely do

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, and that is where we come in.

Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That is our job.

For landlords and multi-site operators

The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.

Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, ready to show insurers, fire officers or EHOs.
