How we handle grease filter exchange in Outwood
Grease filters are the first line of defence in a kitchen extract. Their job is to stop grease getting further into the system, but only while they’re reasonably clean. Our grease filter exchange service swaps dirty filters for clean ones on a schedule. If you have bent or damaged filters that don’t sit properly and blocked baffle filters, we can put it right.
Somewhere as small as Outwood, 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, whatever the size of the place.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Signs you need grease filter exchange in Outwood
Filters get bent and damaged with handling. Damaged filters don’t sit flush, leaving gaps for grease to slip through.
The symptoms we’re asked about most are:
- A canopy running with filters missing
- Filter washing that keeps being missed
- Grease left in baffles after washing
- Damaged filters letting grease past
If you run catering at a healthcare site, such as a hospital like East Surrey Hospital about 2.9 miles north-west, the extract may need cleaning more often than a part-time kitchen.
Questions to ask before booking
- Which accreditations they hold, and whether you can check them
- What insurance they carry
- What hours they’ll be on site
- How areas they cannot reach will be recorded
Between visits
Good habits slow the build-up between visits. Our tips:
- Clean the canopy surfaces regularly
- Never leave gaps in the filter bank
- Keep the extract on whenever the range is in use
- Mention it if the kitchen gets busier
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.
Filter exchange and TR19 cleaning work best together. Setting both up on a schedule keeps everything on track.
What affects the cost of grease filter exchange
The diagnosis comes before the price. We look at:
- One-off work versus a regular cycle
- The number of sites or systems
- Access, including roofs, risers and ceiling voids
- The condition we find in the survey
No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.
What we need to know
Many jobs can be priced from photos and some basics. Send what you can of the following:
- Problems your staff have spotted
- The roof, plant room or outside wall the system runs to
- When the site is open and when it’s quiet
- A few general shots of the system
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
The process
Your trading hours come first. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes anything from a few minutes to an hour or so, depending on the number of filters. Seeing the system in pictures first means the trip to Outwood can be planned properly.
- First, we record the size, type and number of filters in each canopy.
- Together we set how often the filters should be changed.
- On each visit, the dirty filters come out of the canopy.
- Clean filters go straight back in, seated properly with no gaps.
- Anything we notice, such as bent filters or a dirty plenum, is pointed out.
Before we arrive
- Move anything stored near the system
- Mention any locked doors, roof access or ceiling voids
- Tell us where we can park and unload

Grease filter exchange in Outwood: the local picture
Outwood is covered by 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. In Outwood, food businesses are inspected by environmental health officers from Tandridge council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Before-and-after photos from each clean are a simple way to show the extract is in hand.
Term dates shape school work: for a school like Oakwood School, an extract clean fits neatly into a half-term or summer break. Volunteers running a hall kitchen near Church of St John the Baptist, or anywhere in Outwood, may not know when the extract was last cleaned, and a grease test settles it.
Outwood is about 3 miles east of Horley, in Surrey. We provide grease filter exchange for businesses, landlords and public buildings in Outwood and the rest of Surrey. Outwood is one of 395 places in Surrey where we work for commercial clients. You can also see our page for Guildford, roughly 20 miles from Outwood.
All of RH1 is covered for grease filter exchange, from the main roads to the quietest streets. Whether your site is on Miller's Lane, Bellwether Lane and Scott's Hill or a nearby road, we can help. We also cover the places around Outwood: Smallfield (1 mile south), Horley (3 miles west), Burstow (3 miles south), Fernhill (3 miles south-west) and Keeper's Corner (3 miles south).

Around Outwood
Typical jobs here are in premises near The Castle pub and the streets around them. The nearest railway station is Salfords station, about 2.2 miles west. Well-known places in the area include Effingham Park Motor Museum (3.7 miles south) and East Surrey Hospital (2.9 miles north-west). Open spaces near Outwood include Bay Pond and Hedgecourt Lake.
Why deal with it now?
Once filters are saturated, more grease gets past them. That makes the next full clean a bigger job and grease readings can rise between cleans. In a small place like Outwood, a system that fails can take a site out of use.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you are unsure, ring 0345 646 2711 or use the quote form and we will give you an honest view and a fixed quote.

Part by part
The plenum
Clean filters reduce the grease reaching the plenum, but it’s still cleaned during a full TR19 clean.
Mesh filters
Mesh traps grease between its layers, which makes hand-washing hard work.
Your questions about grease filter exchange in Outwood
Can you work in Outwood outside opening hours?
Yes, evening, overnight and weekend work is normal for us. That way a site in Outwood does not have to lose a day’s trading. Tell us your opening hours when you ask for a quote.
Can you get to a site in Outwood?
Yes, smaller places are covered as well as towns. Let us know about access, parking and anything unusual about getting there when you book.
Do you deal with bent or broken filters?
Damaged filters do not seat properly and let grease through. We flag any we find so they can be replaced.
Do you survey before quoting?
Yes, every time. Diagnosis comes before treatment: the survey shows what needs doing and what access we need and the fixed quote is built on it.
What do you do with what you remove?
It’s contained and taken away. Grease, debris and waste water are collected as the work goes on, so it does not spread.
How regularly do grease filters need exchanging?
It varies with the type and amount of cooking. If filters clog early, the interval needs shortening, and we can change it.
Is TR19 a legal requirement?
No, not in itself. TR19® is the benchmark insurers, fire officers and EHOs check against, and many insurance policies ask for proof of TR19® cleaning. The law behind it is the Fire Safety Order 2005 in England and Wales.
What happens if you can’t reach some of it?
They’re marked on the report. In ductwork, new access panels are often the answer, and we can fit those.
Staff cleaning versus specialist work
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
