Book grease filter exchange in Coldharbour

Landlords, agents and facilities managers

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 photos.

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 can quote for the whole system.

About our grease filter exchange in Coldharbour

Think of filter exchange as routine care for the extract. Between full cleans, it keeps the airflow healthy and takes a messy task off your team. The full TR19 clean then gives the system its clean bill of health. The work covers school and hospital kitchens, baffle filters and island canopies, and common reasons people get in touch are staff short of time to wash filters and hand-washed filters that still look greasy.

London kitchens tend to trade late and open early, so work in Coldharbour is normally booked for the night or the early hours. Parking, loading and access to the roof are agreed with the building before the night of the clean.

We’re 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’ve been trading since 2009.

Do you need grease filter exchange in Coldharbour?

Washing filters by hand does not always get them clean. Grease hides in the folds of a baffle or the layers of a mesh, and a quick rinse leaves it there.

Signs it’s time to call us include:

  • Grease dripping from the canopy
  • Poor airflow through the filters
  • A greasy plenum behind the filters
  • Filters so greasy the air can barely pass

A hospital like Poplar Hospital, about 0.6 miles north, is the kind of site where a kitchen may cook for patients, staff and visitors all day.

Questions to ask before you book

  • How VAT is shown on the quote
  • How areas they can’t reach will be recorded
  • Whether the whole system is included, or only the parts that are easy to reach
  • When they can work, and whether that’s outside your opening hours

Questions to ask before you book

Different parts, different methods

Mesh filters

Mesh filters are still found in many canopies. They can be on the same exchange schedule as baffle filters.

Baffle filters

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

How it works

There are three stages on the day: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with photos. Most of the time goes on the work itself, which takes less than an hour in most kitchens. We fit London jobs around the building rather than the other way round, so a visit in Coldharbour is usually out of hours.

  1. We record the number, size and type of your filters.
  2. We set the interval with you.
  3. The dirty set is lifted out.
  4. A clean set is fitted and checked for gaps.
  5. We take the greasy set away and confirm the next date.

How to prepare

  • Clear loose items from the work area
  • Mention any locked doors, roof access or ceiling voids
  • Have your last certificate or report to hand

How to get a quote

Getting a quote does not take long. Call or email with a few details and you will typically have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.

Keeping the system healthy

Simple habits between visits make a real difference. Our advice:

  • Let us know if your cooking hours increase
  • Make sure we can reach the canopy on exchange day
  • Never cook with the extract switched off
  • Make sure no filter is left out

Your team carries on as normal, without the filter washing. Make sure we can reach the canopy on exchange day and let us know of any changes to opening hours.

Filters that are left too long stop protecting the system. A regular cycle keeps the rest of the system cleaner until the next TR19 clean.

Grease filter exchange around Coldharbour

There are about 440 restaurants, cafés and works canteens and about 120 takeaways in and around Coldharbour, up to about a mile and a half out, according to the Food Standards Agency’s register. Any of those kitchens with a canopy relies on its filters to catch grease before it reaches the duct. London jobs usually start after the last service, with loading and roof access agreed with the building first. Coldharbour sits within the area of London Fire Brigade. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.

School kitchens, at schools like Woolmore Primary School for example, are usually cleaned in the holidays so no lunches are lost. If you run a café or takeaway near Canary Wharf station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits.

Leave it or put it right?

Some kitchens in Coldharbour wash filters themselves to save the cost of a service, and that can work if it’s done thoroughly and on time. When it doesn’t happen reliably, an exchange makes it automatic. In a London building, a problem in a duct, damper or fan rarely stays in one unit.

No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.

Your questions about grease filter exchange in Coldharbour

Do you work at weekends in Coldharbour?

Yes, evening, overnight and weekend work is normal for us. The work in Coldharbour can fit around your hours. When you call 0345 646 2711, or send details by email, mention when the site is quiet.

Can school kitchens in Coldharbour be cleaned in the holidays?

Yes, and it’s the easiest time to do it. Around Coldharbour, the Food Standards Agency lists about 46 schools and colleges with registered kitchens within a mile and a half or so. Tell us your holiday dates and we’ll book the visit for when the site is empty.

How much notice should we give?

For planned work, earlier is better, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.

How long does grease filter exchange take?

The work itself takes well under an hour for most canopies. Larger systems naturally take longer, and we will tell you what to expect.

Where do the greasy filters go?

We take them away. That is the point of an exchange: you always have a clean set fitted and nothing greasy left on site.

What accreditations do you have?

Our accreditations are CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.

Is there a survey before the work?

Yes, always. We diagnose before we treat: the survey shows what needs doing and what access we need, and the quote is based on that.

Do you offer maintenance contracts?

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

What your team can do, and what needs us

Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.

Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
