How we handle grease filter exchange in Stotfold Common
A filter service works alongside TR19® cleaning, not instead of it. Fresh filters help limit what gets into the ductwork though vapour still carries some grease past them. So the canopy, plenum and ducts still need their full TR19 clean. We are often asked to deal with filters left unwashed on busy weeks and poor airflow through the filters, on restaurants and pubs, school and hospital kitchens and baffle filters.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, where grease settles in the flat sections. Access, parking and timings are agreed before the day.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

What your team can do, and what needs us
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
When to call us in Stotfold Common
Repeated removal and washing takes its toll on filters. A bent filter doesn’t seat properly and grease passes round them.
Keep an eye out for any of the following:
- Filters so greasy the air can barely pass
- Missing filters in the filter bank
- Damaged filters letting grease past
- A greasy plenum behind the filters
Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Hinxworth Place is about 1.8 miles north-east), access may need planning.

Honest limits
Before booking, it helps to know what’s not included:
- Greasy ducts and risers that a filter change won’t reach
- A canopy that does not capture the vapour properly
- Extraction problems caused by the fan rather than the filters

Grease, kitchens and Stotfold Common
The FSA’s food hygiene register includes about 4 pubs, bars and clubs within about 1.5 miles of central Stotfold Common. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Food hygiene inspections in Stotfold Common are the job of Central Bedfordshire council’s environmental health team. 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. Fire safety in Stotfold Common falls to Hertfordshire Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
Where a hall near Church of Saint Guthlac, or anywhere in Stotfold Common, hosts lunch clubs or events, its extract gathers grease just as a café’s does. Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Fairfield Hospital is the nearest hospital to Stotfold Common, about 1.9 miles south.

For landlords and multi-site operators
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.
How it works
Your staff don’t need to do much 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. For a village or hamlet like Stotfold Common, tell us about narrow lanes, gates and parking when you book.
- The filters in each canopy are measured and counted.
- We set the interval with you.
- 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
- Let us know how we reach the system, including roofs, risers and plant rooms
- Mention any parking or loading restrictions
- Allow time for equipment near the work to be turned off and cool down
Ask for a quote
Some systems can be priced from photos; 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.

What types of premises do you cover?
Commercial premises of every kind: kitchens, offices, schools, healthcare, retail, leisure and food production. We fit the work around how the site operates.
Looking after it afterwards
Good habits slow the build-up between visits. Our tips:
- Make sure no filter is left out
- Report a dripping canopy early
- Don’t let the full clean slip because filters are changed
- Clear anything stored on or near the canopy
Your team carries on as normal, without the filter washing. Make sure we can reach the canopy on exchange day and let us know of any changes to opening hours.
Filters that are left too long stop protecting the system. A regular cycle keeps the rest of the system cleaner between full cleans.
