Grease filter exchange in Bishop's Waltham, done properly
Cleaning filters by hand takes staff time and is easy to put off. With a filter exchange, we bring a clean set and take the dirty one away and the canopy is refilled right away. The work covers wall canopies, school and hospital kitchens and restaurants and pubs, and the jobs we see most are grease filters clogged with grease and poor airflow through the filters.
In a smaller place like Bishop's Waltham, the kitchens with extract systems are more likely to be a pub, a café, a takeaway or a school or care home kitchen than a big restaurant. Quieter kitchens still collect grease in the duct, just more slowly, so the interval is set by hours of use and grease readings.
The sign-off is always in writing: a written report, dated and illustrated with photos, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

Leave it or put it right?
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. Booking now means the visit to Bishop's Waltham is planned around you, not forced by a breakdown.
Working hours, access and the scale of the site can all change the price. Each of those is built into the quote and give you a fixed price before any work starts.

FAQs for Bishop's Waltham
Do you work overnight in Bishop's Waltham?
Yes, we can come after you close and finish before you open. That way a site in Bishop's Waltham does not have to lose a day’s trading. Your opening times are the first thing we ask for.
Who would carry out a food hygiene inspection at a kitchen in Bishop's Waltham?
That is Winchester City council, whose environmental health officers carry out food hygiene inspections in Bishop's Waltham. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
Do you have insurance?
Yes. Duct Doctor is fully insured, and the details are available on request.
Is TR19 a legal requirement?
No. TR19® is BESA’s specification, not legislation. The law is the Regulatory Reform (Fire Safety) Order 2005, which makes the responsible person assess and reduce fire risk, and cleaning to TR19® is the recognised way to show grease is under control.
Which grease filters does the service cover?
We work with both baffle and mesh filters. The first step is recording what you have and set up the service around them.
Can you give a price for filter changes?
It depends on the number and type of filters and how often they’re changed. We will give you a fixed quote, typically within one working day.
Can one contract cover all our sites?
Yes. Our area covers London and the South East, so we can schedule a run of sites as one programme. Every site has its own report.
What accreditations do you have?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.
The process
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool before work begins, and floors and nearby surfaces are sheeted. On site, it takes a short visit, depending on how many filters the canopies hold. We plan the journey to Bishop's Waltham and bring what the job is likely to need.
- We record the number, size and type of your filters.
- We set the interval with you.
- The dirty set is lifted out.
- Clean filters go in and we check they sit snugly.
- The dirty filters leave with us and the next visit is booked.
Before we arrive
- Make sure equipment near the work can be switched off and left to cool
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Move anything stored near the system

Part by part
Baffle filters
Baffle filters are robust and widely used in commercial canopies. They don’t clean themselves as the collected grease builds up between the blades.
School, care home and staff kitchens
A longer exchange interval may suit lighter cooking. We agree the schedule to match.
What your team can do, and what needs us
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Staff cleaning and specialist work are not the same thing. 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.
What affects the quote in Bishop's Waltham
Some jobs are bigger than they look, and some smaller. What affects the quote:
- How big the system is
- Parking and loading at the site
- Access, including roofs, risers and ceiling voids
- A single visit or a regular plan
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we’ll explain each part.
Helping us quote
Many jobs can be priced from pictures and some basics. Useful things to send:
- Close-ups of filters, grilles, hatches or access panels
- Any symptoms, from odd noises to smells or leaks
- Your last certificate, test record or report
- The roof, plant room or outside wall the system runs to
Quoting starts with a diagnosis, either from photos and details you send or from a site visit. After that, you get a fixed price for the work so you know the cost before work begins.
Grease, kitchens and Bishop's Waltham
Food Standards Agency records include about 6 bars, pubs and nightclubs in Bishop's Waltham and the streets around it, up to about 1.5 miles out. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Kitchens in Bishop's Waltham get their food hygiene inspections from Winchester City council. 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. Bishop's Waltham sits within the area of Hampshire and Isle of Wight 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.
Where a hall near Church of St Peter, or anywhere in Bishop's Waltham, hosts lunch clubs or events, its extract gathers grease just as a café’s does. Healthcare kitchens, like those at hospitals such as Moorgreen Hospital (about 5.1 miles west), often cook for long hours, which puts them in BESA’s heavier-use bands. Term dates shape school work: for a school like Bishop's Waltham Junior School, an extract clean fits neatly into a half-term or summer break.

Keeping the system healthy
Here’s the after-treatment advice, short and simple:
- Watch for grease drips between visits
- Don’t refit a filter that’s bent
- Mention it if the kitchen gets busier
- Book full TR19 cleans alongside filter changes
We tell you if we spot anything in the canopy that needs attention. That might mean bringing a TR19® clean forward and we can book that in.
Damaged filters leave gaps in the defence. Replacing them early protects the plenum and ductwork.
