Why act early in Sprig's Alley
Grease-loaded filters are a fire risk in their own right. A flare-up on the range can reach them and grease in the duct can carry a fire further. Keeping filters clean takes some of that fuel away. Somewhere as small as Sprig's Alley, losing a kitchen or building to a fault is felt by everyone who uses it.
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll go through it with you.

Grease filter exchange in Sprig's Alley
Each visit is quick and tidy. We lift out the dirty filters and fit a clean set, and we check they’re seated with no gaps. Anything that needs attention is pointed out. Typical jobs include blocked baffle filters and grease building up behind the canopy filters, on island canopies, wall canopies and school and hospital kitchens.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, and those horizontal sections are where grease settles. We agree access and timings in advance.
Each visit ends with a written report and photos, 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.

How we price grease filter exchange
The survey tells us what the work involves. We look at:
- Access, including roofs, risers and ceiling voids
- Travel, parking and unloading
- What state the system is in
- How big the system is
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you are not sure what’s needed, call 0345 646 2711 or email us and we’ll give you an honest view and a fixed quote.
What to send for a quote
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- Any symptoms, from odd noises to smells or leaks
- The times we could work without disrupting the site
- The roof, plant room or outside wall the system runs to
- Any previous report or certificate
The quickest way to a quote is to send pictures: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and many jobs can be priced from that alone.
What grease filter exchange looks like in Sprig's Alley
Sprig's Alley is covered by Oxfordshire 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. Environmental health officers from Buckinghamshire council inspect food businesses in Sprig's Alley. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A dated certificate in the maintenance file answers the question before it’s asked.

Records are where multi-site compliance often slips. Every visit ends with a dated report and photos, so you can show an insurer or inspector what was done at each site.
What your team can do, and what needs us
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That’s our job.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
What happens on the day
When we arrive, we check the system against the survey or the photos you sent. Anything unexpected is raised with you before we go further. After that, the work takes well under an hour for most canopies. If you can send pictures, we can arrive in Sprig's Alley knowing what to expect.
- The filters in each canopy are measured and counted.
- An exchange schedule is agreed to suit your cooking.
- The dirty set is lifted out.
- Clean filters go in and we check they sit snugly.
- We take the greasy set away and confirm the next date.
Preparing for the visit
- Make sure someone can let us in and lock up afterwards
- Mention any locked doors, roof access or ceiling voids
- Let us know when the site is closed or quiet
Getting a quote
Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.

The plenum
With good filters, less grease ends up in the plenum, but it still needs cleaning as part of TR19.
Do you need grease filter exchange in Sprig's Alley?
Missing filters are more common than you’d think. Every gap in the filter bank lets grease straight into the plenum where it settles out of sight.
Any of these means the system needs a check-up:
- Grease filters clogged with grease
- Missing filters in the filter bank
- A greasy plenum behind the filters
- Bent or damaged filters that do not sit properly
Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Sprig's Alley is Thame Community Hospital, about 5.6 miles north-west.

Common questions in Sprig's Alley
Can you work in Sprig's Alley outside opening hours?
Yes, evening, overnight and weekend work is normal for us. That way a site in Sprig's Alley does not have to lose a day’s trading. Your opening times are the first thing we ask for.
Which fire and rescue service is responsible for Sprig's Alley?
Sprig's Alley is in the area of Oxfordshire Fire and Rescue Service. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Does the law say we must follow TR19?
No, not in itself. Insurers, fire officers and EHOs look to TR19® as the benchmark, and many insurance policies ask for proof of TR19® cleaning. The legal duty sits in the Regulatory Reform (Fire Safety) Order 2005, which applies in England and Wales.
Do you work with multi-site operators?
Yes. Send the list of sites and the work at each and we will quote them together.
What should go in our maintenance log?
Visit reports, certificates and your in-house cleaning logs. They’re what an insurer, fire officer or EHO may ask for, so keep them together and easy to find.
Where does the waste go?
We contain it and take it with us. We collect grease, debris and waste water as we go rather than letting it spread.
Can damaged filters stay in the canopy?
A badly damaged filter should be replaced. We will tell you which ones and why on the visit.
How regularly do grease filters need exchanging?
The right interval depends on the kitchen. If filters clog early, the interval needs shortening and we’ll adjust it.
