Grease trap cleaning in Newnham
A clean trap means flowing drains and no foul smells. The fat, oil, grease and solids are taken out, clean the inside and the baffles and the trap checked before we leave. We’re often asked to deal with gurgling from the sink waste and a bad smell from the sinks or drains, on pot wash sinks, kitchen waste pipes and restaurants and takeaways.
Rural kitchens may drain to a septic tank or a private drain rather than straight into a public sewer, so keeping fat out with a working grease trap matters even more.
Duct Doctor has been trading since 2009, as 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.

Grease trap cleaning around Newnham
There are about 5 restaurants, cafés and works canteens and about 8 takeaways and sandwich shops across Newnham and its immediate surroundings (about a mile and a half), according to the Food Standards Agency’s register. Kitchens like these wash fat, oil and grease down the sink every day, and a grease trap is what stops it reaching the sewer. Environmental health officers from North Hertfordshire council inspect food businesses in Newnham. Walls, floors, ceilings and equipment are all part of what they look at. A record of each deep clean helps show the kitchen is kept in order. Newnham, about 36 miles from central London, is within our usual area. Visits are booked around your hours, evenings and weekends included.
Historic houses such as Hinxworth Place (about 1.4 miles north) are part of the area around Newnham, and if you run event catering at a venue like that, a deep clean between seasons helps. Healthcare kitchens, like those at hospitals such as Fairfield Hospital (about 3 miles south-west), cook for long hours, so deep cleans and grease trap work are planned around patients’ meals.

What’s near Newnham
The closest station to Newnham is Baldock station, about 2 miles south. A little further out are Bygrave House (1.5 miles south-east) and Fairfield Hospital (3 miles south-west). Not far away are Arlesey Old Moat and Glebe Meadows.
Staff cleaning versus specialist work
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.
Leave it or put it right?
A blocked drain can stop a kitchen in its tracks. Water won’t drain away, and dirty water can back up. Keeping the trap clean reduces the risk. Systems in rural buildings are often out of sight and out of mind.

What else we do in Newnham
Part by part
Grease interceptors
Grease interceptors are larger units that serve busier kitchens. With more capacity, they fill more slowly, but they still need regular emptying and cleaning.
Baffles and outlets
The outlet carries the separated water on to the drain. If it’s blocked or greasy, the trap backs up.
Signs you need grease trap cleaning in Newnham
Oil tipped down the drain instead of being collected overloads the trap fast. Small amounts soon build up.
If you notice any of these, it’s worth a diagnosis:
- A regular cleaning plan for the grease trap
- A slow-draining kitchen sink
- An under-sink trap that keeps filling up
- Grease setting in the kitchen pipework
Hall and church kitchens, near Church of St Vincent or anywhere around Newnham, are used by many hands, and periodic deep cleans and grease trap visits keep them in order.
Before booking anyone
- Whether the whole system is included, or only the parts that are easy to reach
- What insurance they carry
- Whether they recommend a next date
- What records you will receive afterwards

Fixed quotes for grease trap cleaning in Newnham
A fixed price needs a few facts first. We look at:
- One-off work versus a regular cycle
- The condition we find in the survey
- Site rules, permits and inductions
- The scale of the work
Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you’re not sure what’s needed, call us on 0345 646 2711, or email photos and we will give you an honest view and a fixed quote.
Helping us quote
Photos let us diagnose from a distance. Try to include:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- The site address and the type of premises
- Detail shots of panels, filters and grilles
- The paperwork from the last visit, if you have it
To get a fixed quote, call us on 0345 646 2711 or use the quote form with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. You’ll normally have a quote within one working day.
Newnham questions
Do you work in villages like Newnham?
Yes, we work in villages as well as towns, and Newnham is covered. Let us know about access, parking and anything unusual about getting there when you book.
Can the work in Newnham be done at night or at weekends?
Yes, we can come after you close and finish before you open. It means the site in Newnham keeps running as normal. Your opening times are the first thing we ask for.
Who is the responsible person?
Under the Regulatory Reform (Fire Safety) Order 2005, it’s the responsible person: normally the employer or whoever controls the premises. Landlords, facilities managers and managing agents can also hold responsibility.
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 kinds of sites do you work on?
Any site with a kitchen or a ventilation system to look after, from a single café to a large school. We work with hotels, schools, care homes, offices, retail and leisure sites.
Will I get paperwork for my records?
Yes, always. It’s a dated, written report with photos, plus a certificate via the BESCA Vent Hygiene Elite portal for TR19® Grease cleans. File it with your fire safety records.
What happens to the waste?
It leaves the site with us when we go. While we work, it’s kept contained to keep the area clean.
Will cleaning the grease trap fix a blocked drain?
A trap clean removes the grease in the trap, and can clear the problem where the trap was the cause. A blockage deeper in the drains needs a drainage specialist.
The process
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. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes a short visit for a small trap and longer for an inline unit or interceptor. Somewhere like Newnham, lanes, gates and parking are worth mentioning in advance.
- We agree a time when the sinks aren’t needed.
- The trap is opened up and checked.
- Built-up grease and food waste are taken out.
- We clean the baffles, inlet and outlet.
- We close it up, check it drains and suggest when it needs cleaning again.
Before we arrive
- Find the previous report, if there is one
- Tell us the best time to work, such as after service or at a weekend
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
