Multi-site and managed buildings

Running several sites is easier with one contractor. We cover South East England and London, so a run of sites can go into one programme and kept to a regular schedule.

For anyone managing more than one site, we can plan visits across the whole estate and price them together. Every building has its own written report, so each one has its own record.

How we handle grease filter exchange in Chelmsford

The filters in the canopy are the first thing cooking vapour meets. They catch grease before it reaches the plenum and ductwork, but only while they’re reasonably clean. Our grease filter exchange service swaps dirty filters for clean ones on a schedule. If you have a greasy plenum behind the filters and filter washing that keeps being missed, we can help.

Kitchens in a place the size of Chelmsford are cleaned around trading, not the other way round: after the last cover, before breakfast or on a day the kitchen is shut. Bigger sites can be done kitchen by kitchen, so cooking carries on elsewhere.

We are 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, and we have been trading since 2009.

What affects the cost of grease filter exchange

Your quote is based on your site. We take into account:

  • The scale of the work
  • Access, including roofs, risers and ceiling voids
  • Site rules, permits and inductions
  • Where the site is and how we reach it

Several systems or sites on one quote often makes better use of the time. Mention every system or site you need covered and we’ll price it together.

What we need to know

When you call or email, it’s useful to have:

  • The site address and the type of premises
  • The times we could work without disrupting the site
  • How we’d reach plant on a roof or in a plant room
  • Wide pictures of the system and the area around it

Getting a quote does not take long. Send a few details and photos, and we usually reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.

Do you need grease filter exchange in Chelmsford?

Repeated removal and washing takes its toll on filters. A bent filter doesn’t seat properly and grease passes round them.

It’s time to book a visit if you see:

  • A canopy that drips grease
  • Missing filters in the filter bank
  • Blocked baffle filters
  • Staff short of time to wash filters

Term dates shape school work: for a school like Trinity Road Primary School, an extract clean fits neatly into a half-term or summer break.

Before you book anyone

  • When the next visit should be, and why
  • Proof of insurance
  • Which accreditations they hold, and whether you can check them
  • Whether the quote is based on a survey or photos

Choosing a duct cleaning contractor

What grease filter exchange looks like in Chelmsford

The FSA’s food hygiene register includes about 52 pubs, bars and clubs and about 4 hotels, B&Bs and guest houses across Chelmsford and its immediate surroundings (about a mile and a half). Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. The fire and rescue service for Chelmsford is Essex County 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 Chelmsford get their food hygiene inspections from Chelmsford council. Extraction counts as kitchen equipment, so its condition can come up on the day. Before-and-after photos from each clean are a simple way to show the extract is in hand.

Church and community hall kitchens, near Church of the Holy Trinity or anywhere around Chelmsford, are easy to forget, but their extracts collect grease like any other. If you cook for passing trade around Chelmsford station, the extract can be cleaned between your last and first customer.

How it works

Protection comes first: 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 anything from a few minutes to an hour or so, depending on the number of filters, and we clear up before we go. Phased working suits larger sites in a place the size of Chelmsford, with each part handed back before the next starts.

  1. We look at the canopies and the condition of the filters.
  2. Any damaged or missing filters are noted.
  3. Greasy filters are swapped for clean ones.
  4. We check the filters are seated and the canopy is ready to use.
  5. We tell you if the plenum or canopy needs a clean.

Getting ready for the visit

  • Tell us the best time to work, such as after service or at a weekend
  • Mention any sign-in, permit or induction we need
  • Move anything stored near the system

Advice

What staff can safely do

Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.

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.

How the job changes from site to site

The plenum

Heavy grease in the plenum often follows clogged or missing filters, or that a full clean is due.

Canopy filter housings

Grease collects in the channels and drip trays below the filters. We point it out if it needs cleaning.

Looking after it afterwards

So the system stays in good health:

  • Report a dripping canopy early
  • Never cook with the extract switched off
  • Clean the canopy surfaces regularly
  • Keep the canopy clear for exchange visits

The next exchange is already in the diary. If the kitchen gets busier, the interval can be shortened to keep up.

Saturated filters let more grease through. Getting onto a regular exchange now keeps grease out of the plenum and ductwork between full cleans.

Chelmsford questions

Who is the fire and rescue service for Chelmsford?

Fire safety enforcement in Chelmsford is handled by Essex County Fire and Rescue Service. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.

Do you do school kitchen extract cleaning in Chelmsford in the summer holidays?

Yes, and it’s the easiest time to do it. The FSA’s register shows about 33 schools and colleges with food registrations within roughly a mile and a half of Chelmsford. Booking early in the term gives the best choice of holiday dates.

Where does the waste go?

It leaves the site with us when we go. While we work, it’s kept contained so the area stays clean.

How do you protect the area?

By covering it before any work starts. We keep the work contained and leave the area clean.

How much notice do you need?

The more notice, the better, particularly for night and weekend visits. We normally quote within one working day, and emergencies are covered by our 24/7 line.

What if parts of the system can’t be reached?

They’re listed in the report, never skipped quietly. The report says which parts couldn’t be reached and why, and we can quote to improve the access.

What does grease filter exchange cost?

It depends on the number and type of filters and how often they’re changed. We will give you a fixed quote, normally within one working day.

What if some of our filters are damaged?

Each filter is looked at when we exchange. Any that are bent or damaged are flagged since a poor fit lets grease past.
