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, next to our reports.

Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.

About our grease filter exchange in Merrow

Grease filters are the first line of defence in a kitchen extract. 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’re dealing with smoke and heat lingering under the hood and grease filters clogged with grease, we can put it right.

Size does not change the work: a kitchen in a place like Merrow gets the whole system cleaned, canopy to discharge. We plan the visit around your hours, with the journey sorted in advance.

It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we are fully insured.

Managing agents and facilities teams in Merrow

We also work for facilities teams across offices, schools and healthcare across Surrey. Larger estates can be phased building by building to keep disruption down.

Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we’re happy to quote for all of it.

Questions from Merrow

Who enforces fire safety at workplaces in Merrow?

Merrow is in the area of Surrey Fire and Rescue Service. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.

Can you come to Merrow after we close?

Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. Your opening times are the first thing we ask for.

How regularly do grease filters need exchanging?

The right interval depends on the kitchen. If filters are dripping or clogging before the next change, it’s too long, and we can change it.

Which sectors do you work in?

We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.

Can we skip TR19 cleans if the filters are changed regularly?

No, the two work together. A TR19® clean deals with the whole system, with a certificate and photo report.

Do you work with multi-site operators?

Yes. Our area covers London and the South East, so we can schedule a run of sites as one programme. Every site has its own report.

Do you offer emergency callouts?

Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.

Can you set up regular visits?

Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. Each report recommends when the next visit should be.

Keeping the system healthy

Aftercare is simple, and it makes the next visit easier:

  • Don’t let the full clean slip because filters are changed
  • Mention it if the kitchen gets busier
  • Report damaged filters so they can be replaced
  • Never leave gaps in the filter bank

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

Damaged filters leave gaps in the defence. Sorting them now keeps grease where it can be caught.

Why it’s worth doing now in Merrow

Changing filters on schedule costs far less disruption than a blocked extract. It’s one of the simplest parts of looking after the system, and one of the easiest to let slip. Light use slows the build-up but does not stop it.

Working hours, access and the scale of the site all affect the cost. We take each of them into account, and the price is fixed before work begins.

Why book with us

  • In business since 2009
  • One contact for all your sites in London and the South East
  • We’re fully insured
  • Work around your opening hours, with 24/7 emergency cover

See our cost guide and how to check a contractor.

What grease filter exchange cannot fix

We won’t sell you work that doesn’t address the problem, so here are the limits:

  • A canopy that needs a proper clean
  • Extraction problems caused by the fan rather than the filters
  • Grease already built up in the ductwork, which needs a full TR19 clean

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

What we work on in Merrow

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

How the visit works

Your trading hours come first. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes a short visit, depending on how many filters the canopies hold. Evenings, weekends or a closed day all work for a site in a place like Merrow.

  1. We start by noting how many filters you have and what type they are.
  2. A change schedule is agreed to match the kitchen’s cooking hours.
  3. At each visit, the greasy filters are lifted out.
  4. We fit clean filters and check they sit snugly in the housing.
  5. If a filter is damaged or the plenum needs attention, we tell you.

How to prepare

  • Make sure someone can let us in and lock up afterwards
  • Tell us where we can park and unload
  • Tell us about site rules, permits or sign-in

Grease, kitchens and Merrow

The FSA’s food hygiene register includes about 8 bars, pubs and nightclubs in Merrow and the streets around it, up to about 1.5 miles out. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Merrow sits within the area of Surrey 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. Food hygiene inspections in Merrow are the job of Guildford council’s environmental health team. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A dated certificate in the maintenance file answers the question before it’s asked.

Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; St. Luke’s Hospital is the nearest hospital to Merrow, about 1.5 miles south-west. A hall kitchen that only cooks for events, whether near Church of St John the Evangelist or elsewhere in Merrow, still needs its extract cleaned, just less often. Bursars and site managers at schools such as Bushy Hill Junior School tend to book extract cleaning for when the kitchen is empty.
