Grease filter exchange in Dorchester
A filter that doesn’t sit right lets grease straight past. Bent, damaged or missing filters leave gaps, so we check every one at each visit. Damaged filters are flagged so they can be replaced. We are often asked to deal with filters that come out of the sink still dirty and weak extraction at the canopy, on school and hospital kitchens, restaurants and pubs and mesh filters.
Somewhere as small as Dorchester, 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 are fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

What happens if it’s left?
Filters full of grease are fuel sitting right above the cooking. A flare-up on the range can reach them, and from there into the duct. Clean filters mean less fuel in the canopy. A fault that closes a site in a village like Dorchester affects everyone who depends on it.
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we will go through it with you.

Common questions in Dorchester
Which fire service covers Dorchester?
Oxfordshire Fire and Rescue Service is the fire and rescue service for Dorchester. TR19® isn’t law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
Is Dorchester within the area you cover?
Yes. Villages and rural sites across the South East are part of our work, Dorchester included. Just mention lanes, gates or anything else about the site when you book.
Are you insured?
Yes, fully. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.
Where does the waste go?
It leaves the site with us at the end of the visit. During the work, it’s contained to keep the area clean.
Will I get paperwork for my records?
Yes. Every visit ends with a written report and photos, covering the work, any areas we couldn’t access and the recommended next date. Where the work is a TR19® Grease clean, there’s also a certificate issued through the BESCA Vent Hygiene Elite portal.
Which sectors do you work in?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, as well as food production and leisure sites.
How long will you be on site?
That depends on how much there is to do, but for a typical site it takes anything from a few minutes to an hour or so, depending on the number of filters. We’ll give you a better idea when we quote.
What if parts of the system cannot be reached?
They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
What grease filter exchange looks like in Dorchester
In Dorchester, food businesses are inspected by environmental health officers from South Oxfordshire council. Extraction counts as kitchen equipment, so its condition can come up on the day. Keeping each certificate and photo report on file helps show the extract is looked after. Dorchester is about 47 miles from central London, well within the area we cover across London and the South East. The visit is fixed around your opening hours, not ours.
Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Clifton Hampden Manor is about 2 miles west), access may need planning. A hospital like Littlemore Hospital, about 5.6 miles north-west, is the kind of site where a kitchen may cook for patients, staff and visitors all day. Where a hall near Dorchester Abbey, or anywhere in Dorchester, hosts lunch clubs or events, its extract gathers grease just as a café’s does.
Dorchester is about 4 miles north-east of Didcot, in Oxfordshire. Every kind of commercial site in Dorchester, grease filter exchange is something we can help with. Visits can be booked for evenings, overnight or weekends so the site keeps running. Dorchester is one of 443 places in Oxfordshire where we work for commercial clients. For sites nearby, see our Oxford page, about 8 miles away.
Every address in OX10 is covered for grease filter exchange, from busy streets to back roads. If you need grease filter exchange at premises on High Street, Queen Street and Queens Close or a nearby road, we can help. If your site is just outside Dorchester, we cover Burcot (1 mile north-west), Little Wittenham (1 mile south-west), Berinsfield (1 mile north), Warborough (1 mile east) and Shillingford (1 mile south-east). We also work in nearby towns such as Oxford (8 miles north), Didcot (4 miles south-west), Abingdon-on-Thames (5 miles north-west), Thame (11 miles north-east), Wantage (12 miles west) and Henley-on-Thames (14 miles south-east).
Landmarks near Dorchester
Around Dorchester, our work takes us to kitchens and buildings near The White Hart Hotel Bar. The nearest railway station is Culham station, about 3.1 miles west. Other landmarks nearby include Brightwell Castle (2.3 miles south) and Littlemore Hospital (5.6 miles north-west). Not far away are Ewelme Watercress Beds and Wittenham Clumps.
In-house cleaning or a specialist?
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
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. That part needs specialist access and equipment.
For landlords and multi-site operators
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We can quote either party and send the paperwork to whoever needs it.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we’re happy to quote for all of it.

Aftercare tips
Once we’ve finished, these simple steps help:
- Mention it if the kitchen gets busier
- Look out for drips from the canopy
- Don’t refit a filter that’s bent
- Keep filter exchange and TR19 cleaning on the same plan
Your team carries on as normal, without the filter washing. Just keep the canopy clear for the next visit and tell us if service times change.
Saturated filters let more grease through. Getting onto a regular exchange now keeps grease out of the plenum and ductwork between full cleans.
How it works
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 anything from a few minutes to an hour or so, depending on the number of filters. Rural roads and tight entrances are worth telling us about before a visit to Dorchester.
- We count and measure the filters in every canopy.
- Together we set how often the filters should be changed.
- On each visit, the dirty filters come out of the canopy.
- We fit clean filters and check they sit snugly in the housing.
- If a filter is damaged or the plenum needs attention, we tell you.
How to prepare
- Let us know about permits to work or site inductions
- Allow time for equipment near the work to be turned off and cool down
- Mention any locked doors, roof access or ceiling voids
Get a fixed quote
Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.

When it’s something else
To be straight with you, there are a few things this work won’t fix:
- A canopy too small for the cooking beneath it
- Grease already built up in the ductwork, which needs a full TR19 clean
- Smell complaints that need odour control equipment
Not sure which it is? You can ring 0345 646 2711, or email photos and we will tell you honestly.

What affects the cost of grease filter exchange
We quote each job individually. These are the things that affect it:
- Whether we need access equipment or extra panels
- The scale of the work
- The number of sites or systems
- Working hours and out-of-hours timing
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 you’ll get one fixed quote.
What to send for a quote
When you call or email, it’s useful to have:
- When the site is open and when it’s quiet
- Any symptoms, from odd noises to smells or leaks
- Where the site is and what kind of site it is
- Photos showing the whole system and its surroundings
Every quote begins with a look at the system, from your pictures and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work, before we start.
