Grease Filter Exchange in Knaphill
Grease filter exchange for Knaphill, with a survey first and a report with photos at the end. Call for a fixed quote.
- Gaps where filters have been removed
- Weak extraction at the canopy
- Filters left unwashed on busy weeks
Looking after it afterwards
Once we’ve finished, these simple steps help:
- Do not let the full clean slip because filters are changed
- Mention it if the kitchen gets busier
- Clear anything stored on or near the canopy
- Report a dripping canopy early
Keep an eye out for filters that have been taken out. Gaps let grease into the plenum, so let us know if one goes missing or gets damaged.
If cooking has stepped up, the filter schedule should too. Changing the interval early stops grease building up unseen behind the canopy.
Grease filter exchange in Knaphill
Good filters only work when they fit properly. Bent, damaged or missing filters leave gaps, so we check every one at each visit. We point out any that need replacing. If you’re dealing with filters that leave gaps in the canopy and grease building up behind the canopy filters, we can help.
Kitchens around a place like Knaphill are often in older buildings or single-storey extensions, where the duct may cross a roof void or climb an outside wall. Flat runs collect grease and need proper access to clean.
Accreditations are easy to claim and worth checking. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Your questions about grease filter exchange in Knaphill
Do you work overnight in Knaphill?
Yes, out-of-hours work is a big part of what we do. It means the site in Knaphill keeps running as normal. Let us know the hours you are closed and we will book within them.
Which fire and rescue service is responsible for Knaphill?
Fire safety enforcement in Knaphill is handled by Surrey Fire and Rescue Service. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Do you survey before quoting?
Yes. We always survey first, either from photos and details you send or on a site visit. A fixed quote follows.
Do you work in Knaphill?
Yes. We work in Knaphill and across Surrey, within our South East and London area. For a fixed quote, call 0345 646 2711 or drop us a line.
Who is responsible for fire safety on the premises?
The Fire Safety Order 2005 calls them the responsible person: normally the employer or whoever controls the premises. In shared or managed buildings, a landlord, facilities manager or managing agent can share the duty.
What do you do to protect the area?
With sheeting and covers, before anything else happens. We keep the work contained and clean down when we finish.
Is filter exchange enough instead of a full extract clean?
No, the two work together. TR19® cleaning covers the canopy, plenum, ductwork and fan, with a certificate and photo report.
Where does the waste go?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. None of it is left on site.

Other services in Knaphill
Grease, kitchens and Knaphill
According to Food Standards Agency records, there are about 7 pubs and bars across Knaphill 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. Kitchens in Knaphill get their food hygiene inspections from Woking council. 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. Surrey Fire and Rescue Service covers Knaphill. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
Bursars and site managers at schools such as Knaphill School tend to book extract cleaning for when the kitchen is empty. Church and community hall kitchens, near St Hugh of Lincoln's Church or anywhere around Knaphill, are easy to forget, but their extracts collect grease like any other. A hospital like Brookwood Hospital, about less than half a mile south, is the kind of site where a kitchen may cook for patients, staff and visitors all day.

What happens if it’s left?
Once filters are saturated, more grease gets past them. The ductwork then loads up faster and grease readings can rise between cleans. You choose the date of a planned visit, and a breakdown never asks.
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll explain each part.

What grease filter exchange can’t fix

In-house cleaning or a specialist?
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
What affects the quote in Knaphill
We don’t publish a price list, because sites vary so much. What we look at:
- How big the system is
- Where the site is and how we reach it
- A single visit or a regular plan
- Whether several sites go on one quote
Working hours, access and the scale of the site can all change the price. We take each of them into account, and the price is fixed before work begins.
What we need to know
Photos let us diagnose from a distance. The most useful are:
- The site address and the type of premises
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Wide pictures of the system and the area around it

What happens on the day
There’s very little for your team to do on the day. A contact on site lets us in at the agreed time and points us to the system, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. Evenings, weekends or a closed day all work for a site in a place like Knaphill.
- First, we check the canopies and the filters in them.
- We note any filters that are bent, damaged or missing.
- Greasy filters are swapped for clean ones.
- We check the filters are seated and the canopy is ready to use.
- Anything that needs attention, such as a greasy plenum, is pointed out.
Getting ready for the visit
- Dig out any earlier paperwork for the system
- Name a contact who can let us in at the agreed time
- Mention any parking or loading restrictions
Ask for a quote
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before work begins.
Advice
How the job changes from site to site
Baffle filters
Baffle filters use overlapping metal blades that force the air to change direction. Grease drops out as it does.
Mesh filters
Older or smaller canopies often use mesh filters. We exchange them on the same basis as baffles.
