About our grease trap cleaning in Preston
Think of the grease trap as a filter for the kitchen’s drains. When it’s looked after, you hardly know it’s there, but neglected, it causes blockages and smells. A regular clean keeps it healthy. If you are dealing with foul odours from the grease trap and sinks that drain slowly, we can put it right.
Fat, oil and grease poured down drains helps form fatbergs, and London’s sewers have made the news for them more than once. A grease trap that’s emptied and cleaned regularly keeps fat out of the drains.
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 are fully insured.

What affects the cost of grease trap cleaning
A fixed price needs a few facts first. We check:
- A single visit or a regular plan
- How easy every part is to reach
- Parking and loading at the site
- The scale of the work
The cost depends on the size of the system, what state it’s in and how easy it is to reach. You get a fixed price before work begins, so you know where you stand.
Helping us quote
Before you ask for a quote, gather:
- The postcode and the type of business
- Photos showing the whole system and its surroundings
- Your opening hours and when the area is out of use
- The paperwork from the last visit, if you have it
Quotes are quick. Send a few details and photos, and we usually reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.

What happens on the day
At the end of the visit, someone from your team can look over the work with us. We point out anything that couldn’t be reached or needs a follow-up, and the same goes into the written report. The visit takes an hour or two in most kitchens, depending on the size and condition of the trap. For a job in Preston, tell us about loading bays, permits, lifts and roof access when you book.
- We find the trap and check how it’s connected.
- We ask for the sinks that drain into the trap not to be used.
- We take out the layer of fat, oil and grease and any solids.
- We clean the chambers, baffles and connections.
- We put it back together, run water through and remove the waste.
Getting ready for the visit
- Move anything stored near the system
- Arrange a key holder or contact on site
- Tell us the best time to work, such as after service or at a weekend
Ask for a quote
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.

When something else is needed
We will not sell you work that doesn’t address the problem, so these are the things it won’t cover:
- Drains that need jetting rather than trap cleaning
- Blockages further down the drainage network
- Drains that are cracked or have collapsed
Not sure which it is? You can call 0345 646 2711 or send us an email and we’ll tell you honestly.
Where we work
- School and care home kitchens
- Pot wash sinks
- Restaurants and takeaways
- Inline grease traps
- Under-sink grease traps
- Kitchen waste pipes
Common problems we fix in Preston
Hot water and detergent carry grease further than you’d expect. When it cools, the grease hardens, often in the trap or the pipe beyond.
The symptoms we are asked about most include:
- An overdue grease trap
- An under-sink unit that needs regular emptying
- An inline trap or interceptor due for cleaning
- Gurgling from the sink waste
If you run a kitchen near South Kenton station with long trading hours, grease builds up faster behind equipment and in the trap.

FAQs for Preston
Do you work overnight in Preston?
Yes, evening, overnight and weekend work is normal for us. The work in Preston can fit around your hours. Tell us your opening hours when you ask for a quote.
Who carries out food hygiene inspections in Preston?
Kitchens in Preston are inspected by Brent council’s environmental health officers. An officer may look behind equipment and at drains, so it pays to have the deep clean booked before those areas build up.
Can you clear our blocked drains as well?
Our service covers the grease trap itself. If the drain beyond the trap is blocked or damaged, we will tell you so you can call a drainage contractor.
How much notice should we give?
The more notice, the better, especially for out-of-hours work. We usually quote within one working day, and there’s a 24/7 line for emergencies.
What happens if a grease trap isn’t cleaned?
Grease escapes into the drains when the trap is full. It sets there and narrows the pipes and causes blockages. Keeping the trap clean stops that happening.
Do you provide a certificate or report?
Yes. Each visit ends with a written report and photos, showing what was done, anything we couldn’t reach and when the next visit is due. Kitchen extract cleans to TR19® Grease also get a certificate through the BESCA Vent Hygiene Elite portal.
Does the law say we must follow TR19?
No. TR19® is BESA’s specification, not legislation. The legal duty comes from the Regulatory Reform (Fire Safety) Order 2005: the responsible person must assess and reduce fire risk, and TR19® is the benchmark for showing that grease in the extract is under control.
What is TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.
Commercial kitchens in Preston
Food Standards Agency records list about 6 food manufacturers and packers in Preston and the streets around it, up to about 1.5 miles out. Where food is made in quantity, grease traps fill faster and need a tighter schedule. Food hygiene inspections in Preston are the job of Brent council’s environmental health team. The state of floors, drains and hard-to-reach corners all feeds into the inspection. Keeping a record of deep cleans and grease trap visits helps at inspection time. Fat from London kitchens contributes to sewer blockages, which is why grease traps need emptying on a schedule.
For schools such as Preston Park Primary School, deep cleans and grease trap work are normally booked for the holidays. St. Mark's Hospital, about 1.1 miles west, is the nearest hospital to Preston; healthcare kitchens can’t stop cooking, so deep cleans are worked around meal times.

Why act early in Preston
A blocked drain can stop a kitchen in its tracks. Sinks will not empty, and dirty water can back up. Cleaning the grease trap on time helps prevent it. A busy site in Preston builds up dirt and wear quickly, so putting it off makes the eventual job larger.
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we will explain each part.

Multi-site and managed buildings
Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept on a regular cycle.
From a single site to a large estate, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Staff cleaning versus specialist work
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
