About our ductwork cleaning in Bishop's Waltham
Duct Doctor has cleaned kitchen extract ductwork since 2009, working across London and the South East. As a BESCA Vent Hygiene Elite member, our duct cleaning is done to BESA TR19® Grease, with each certificate issued through the BESCA portal. We’re often asked to deal with thick crusts of old grease along the duct and ductwork that has never been cleaned, across multi-storey ducts, vertical risers and bends and junctions.
For a smaller kitchen near Bishop's Waltham, a TR19® clean is the same job as anywhere: canopy, filters, plenum, duct, fan and discharge. We plan the visit around your hours, with the journey sorted in advance.
The sign-off is always in writing: a written report, dated and illustrated with pictures, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

Common problems we fix in Bishop's Waltham
Grease in a duct running from a kitchen in Bishop's Waltham is as much a fire risk as in any building. Once it lights, fire can spread along the duct and into other areas, which is why the responsible person needs it under control.
Most sites get in touch when they notice one of these:
- A duct clean needed for an insurer
- A duct nobody has opened in years
- Smells of old cooking grease from the ductwork
- Years of grease along the duct floor
School kitchens, at schools like Bishop's Waltham Junior School for example, are normally cleaned in the holidays so no lunches are lost.
Questions to ask before you book

Why act early in Bishop's Waltham
Grease left in a duct in Bishop's Waltham hardens over time. Heat and age turn it into a thick, stubborn crust, so the later the clean, the bigger the job. Around Bishop's Waltham, a kitchen or building out of action is missed straight away.
The price reflects the work, not guesswork. That is why we survey first, from photos or on site, and the price is agreed before work begins.

How we price ductwork cleaning
The survey tells us what the work involves. The main factors are:
- A single visit or a regular plan
- How many systems or sites are involved
- Working hours and out-of-hours timing
- How big the system is
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.
Asking for a quote
To help us quote quickly, please include:
- Close-ups of filters, grilles, hatches or access panels
- The postcode and the type of business
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- When the site is open and when it’s quiet
Here’s what helps us quote: where the site is, what it is and its opening hours, pictures of the system and any previous report or certificate. Then give us a ring on 0345 646 2711 or drop us a line.
Keeping the system healthy
No system stays clean for ever, but care slows the build-up. A few tips:
- Don’t block access panels with shelving or stock
- Ask us about extra access panels where sections can’t be reached
- File each certificate and photo report in the maintenance log
- Never cook with a filter missing
When the duct is cleaned as part of a full TR19® Grease clean, a TR19 certificate is issued through the BESCA Vent Hygiene Elite portal. It records the date, the location and the technician.
Book the next duct clean before the date passes. If the kitchen starts cooking longer hours, the interval may need to shorten, and grease thickness testing will show it.
The process
A visit follows the same order every time: sheeting and protection first, make the system safe, carry out the ductwork cleaning, clear away and hand over the paperwork. On site, the work takes a shift or more, depending on the length of the runs and the number of access points. Visits to a place like Bishop's Waltham are planned ahead, so we arrive with what the survey says the job needs.
- Diagnosis: a survey of the duct’s route, size and access.
- A fixed quote follows, based on what we found.
- We clean section by section, working from panel to panel.
- We take extra care at bends and at the foot of risers.
- Readings, photos and a recommended next clean date complete the job.
Before we arrive
- Let us know about parking and loading
- Plan for cooking equipment or plant to be off before we arrive
- Make sure someone can let us in and lock up afterwards
Getting a quote
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
Advice
Part by part
Attenuators and discharge
The discharge is where the duct ends and air leaves the building. It can gather grease and mark the wall or roof around it, so it’s cleaned as far as safe access allows.
Horizontal duct runs
Long horizontal runs need access panels at regular intervals. Any stretch out of reach is noted and can fit extra panels.
Ductwork cleaning around Bishop's Waltham
According to Food Standards Agency records, there are about 6 pubs and bars within about 1.5 miles of central Bishop's Waltham. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. Fire safety in Bishop's Waltham falls to 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. Kitchens in Bishop's Waltham get their food hygiene inspections from Winchester City council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
If you run catering at a healthcare site, such as a hospital like Moorgreen Hospital about 5.1 miles west, the extract may need cleaning more often than a part-time kitchen. If you run a church or community hall kitchen, near Church of St Peter or elsewhere in Bishop's Waltham, its extract still collects grease from every lunch and event.
