Northumberland Heath grease filter exchange
Specialist grease filter exchange for Northumberland Heath: diagnosis first, then a fixed quote, the work and a report with photos. Ask us for a fixed quote.
- A greasy plenum behind the filters
- Filters so greasy the air can barely pass
- Poor airflow through the filters
What happens on the day
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes well under an hour for most canopies. Loading bays, visitor permits and roof access are the first things we ask about for a site in Northumberland Heath.
- We count and measure the filters in every canopy.
- Together we set how often the filters should be changed.
- Each visit starts with the used filters being removed.
- Clean, dry filters are fitted in their place, with no gaps left between them.
- If a filter is damaged or the plenum needs attention, we tell you.
Before we arrive
- Clear the space around the work
- Mention any sign-in, permit or induction we need
- Find the previous report, if there is one
Ask for a quote
The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.

How we handle grease filter exchange in Northumberland Heath
Across Northumberland Heath, our filter exchange suits restaurants, pubs, cafés, schools, care homes and other kitchens, whether there’s one canopy or many. We can come before or after service, so cooking is not interrupted. If you are dealing with a canopy running with filters missing and filters that come out of the sink still dirty, we can put it right, from wall canopies, island canopies and mesh filters onwards.
London kitchens tend to trade late and open early, so work in Northumberland Heath 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.
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.

Kitchen extracts in Northumberland Heath
The FSA’s food hygiene register includes about 34 bars, pubs and nightclubs within roughly a mile and a half of the centre of Northumberland Heath. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Night work suits London kitchens, and roads and loading bays tend to be quieter too. Kitchens in Northumberland Heath get their food hygiene inspections from Bexley council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Before-and-after pictures from each clean are a simple way to show the extract is in hand.
School kitchens, at schools like King Henry School for example, are normally cleaned in the holidays so no lunches are lost. If you cook for passing trade around Barnehurst station, the extract can be cleaned between your last and first customer.

What staff can safely do
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
When to call us in Northumberland Heath
Kitchens in Northumberland Heath, as everywhere, find filter washing slips down the list on busy weeks. A missed wash or two is all it takes for filters to fill with grease.
Look out for these warning signs:
- Grease building up behind the canopy filters
- Poor airflow through the filters
- Staff short of time to wash filters
- Bent or damaged filters that don’t sit properly
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Erith and District Hospital is the nearest hospital to Northumberland Heath, about within half a mile north.
Questions to ask before you book
- Exactly which parts of the system are covered
- Whether the quote shows VAT
- Whether they recommend a next date
- If they look at the system before pricing
How we price grease filter exchange
The diagnosis comes before the price. We look at:
- The condition we find in the survey
- Whether we need access equipment or extra panels
- The scale of the work
- A single visit or a regular plan
Combining work into one visit or one programme often makes better use of the time. Tell us about everything you’d like looked at and we will price it together.
Helping us quote
There’s no need for technical detail. Just send:
- The times we could work without disrupting the site
- The site address and the type of premises
- A few general shots of the system
- Detail shots of panels, filters and grilles
Here’s what helps us quote: the address, the type of site and when it’s open, pictures of the system and any previous report or certificate. Then call 0345 646 2711 or drop us a line.

Northumberland Heath questions
Who is the fire and rescue service for Northumberland Heath?
That is London Fire Brigade. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Who inspects food businesses in Northumberland Heath?
Kitchens in Northumberland Heath are inspected by Bexley council’s environmental health officers. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Where do the greasy filters go?
They leave with us. That’s how an exchange works: clean filters in, dirty ones out and nothing greasy left on site.
What do you do to protect the area?
We start with protection: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.
Do you work with multi-site operators?
Yes. You deal with one contact for every site in our area, with visits on a regular schedule.
How much notice do you need?
It depends on the time you need and how big the job is. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.
Is filter exchange enough instead of a full extract clean?
It is not. The rest of the system still collects grease at an interval set by risk assessment.
What accreditations do you have?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We are fully insured and have been trading since 2009.
Why act early in Northumberland Heath
For any kitchen in Northumberland Heath, filters cannot stand in for a full TR19 clean. But clean filters do help the system between cleans, and that shows when the next clean comes round. A building in Northumberland Heath may have flats or offices above and alongside, and a fault in the system can affect them too.
One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. You will have a fixed price before we start.

How the job changes from site to site
School, care home and staff kitchens
Lighter kitchens can often go longer between changes. We agree the schedule to match.
Baffle filters
Baffle filters are robust and widely used in commercial canopies. They still need regular cleaning, because the grease they collect builds up.
