Grease trap cleaning in Harrow
Kitchens in Harrow use us for grease trap cleaning, from small under-sink units to inline traps and interceptors. Visits are booked around your service so washing up is not interrupted. The work covers kitchen waste pipes, inline grease traps and restaurants and takeaways, and common reasons people get in touch are an interceptor full of grease and solids and washing-up water that won’t drain away.
Every food business in London is inspected by its local council’s environmental health officers, and the cleanliness of the whole kitchen is part of what they look at. A deep clean ahead of an inspection, or after one, is a common reason kitchens in Harrow get in touch.
A written report with photos follows every visit, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

What a clean won’t put right
It’s worth knowing the limits before booking:
- Broken pipework below ground
- A trap undersized for the amount of cooking
- Blockages in the public sewer beyond the property
If you’re not sure, just give us a ring on 0345 646 2711 or use the quote form and we will give you a straight answer.
Parts of the system we cover
- Inline grease traps
- Pot wash sinks
- Under-sink grease traps
- School and care home kitchens
- Restaurants and takeaways
- Kitchen waste pipes
Common problems we fix in Harrow
Waste cooking oil poured down the sink overloads the trap fast. Small amounts soon build up.
It’s time to book a visit if you see:
- Drains that gurgle and bubble
- Scheduled grease trap emptying
- Sinks that drain slowly
- A bad smell from the sinks or drains
If you run a care home or healthcare kitchen near Harrow (the nearest hospital is Clementine Churchill Hospital, about 1 mile south-east), a grease trap on a set schedule avoids a blocked drain mid-service.

Grease trap cleaning around Harrow
Look up Harrow on the FSA’s food hygiene register and you’ll find about 280 cafés, restaurants and staff canteens and about 127 takeaways and sandwich shops in Harrow and the streets around it, up to about 1.5 miles out. Kitchens like these wash fat, oil and grease down the sink every day, and a grease trap is what stops it reaching the sewer. Fat from London kitchens contributes to sewer blockages, which is why grease traps need emptying on a schedule. Environmental health officers from Harrow council inspect food businesses in Harrow. An inspection covers the structure of the kitchen as well as the food. Keeping a record of deep cleans and grease trap visits helps at inspection time.
If you run a church or community hall kitchen, near Church of St Peter or elsewhere in Harrow, a deep clean and an emptied grease trap before a busy season of events are worth booking. If you serve passing trade near Harrow-on-the-Hill station, a grease trap on a regular schedule keeps the drains running through busy weeks.

How we price grease trap cleaning
The price is fixed before any work begins. It’s based on:
- Travel, parking and unloading
- What state the system is in
- Access, including roofs, risers and ceiling voids
- Whether several sites go on one quote
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.
Helping us quote
We can often survey from pictures. Try to include:
- The site address and the type of premises
- How we’d reach plant on a roof or in a plant room
- Any access panels or hatches you can see
- A few general shots of the system
Every quote begins with a look at the system, from your pictures and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work so you know the cost before work begins.
What staff can safely do
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, alongside our reports.
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That’s our job.
How the visit works
Protection comes first: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. It takes anything from under an hour to a few hours, depending on the trap, and we clear up before we go. If your building in Harrow has sign-in rules, permits or key holders, mention them when you book.
- We locate the trap and check how it’s fitted.
- We make sure nothing drains into the trap.
- We empty out the fat, oil, grease and solids.
- We clean every part of the inside.
- The trap is refitted, tested with water and the waste taken away.
Before we arrive
- Plan for cooking equipment or plant to be off before we arrive
- Let us know about parking and loading
- Move anything stored near the system

Landlords, agents and facilities managers
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.
Whether it’s one building or many, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with photos.
Harrow questions
How do you handle parking and loading in Harrow?
London parking can be tight, so details of loading bays and permits help. Much of our London work is done overnight, which helps.
Who would carry out a food hygiene inspection at a kitchen in Harrow?
Food hygiene inspections in Harrow are carried out by Harrow council. Photos from a deep clean are a simple record of what was done and when.
Will you tell us when the next visit is due?
Yes. The interval depends on how much the system is used and what we find, and we explain the reasoning on the report.
Do you work in Harrow?
Yes. Our area takes in London and the counties of South East England, and that includes Harrow.
Where does the grease from the trap go?
We remove all the waste we take out. None of it goes back into the drains, of course.
Can we book visits on a schedule?
Yes, of course. Tell us what you have and how it’s used and we’ll propose a schedule with a fixed quote.
What’s the right interval for grease trap cleaning?
It depends on the size of the trap and how busy the kitchen is. Small under-sink units fill faster than larger traps and the busier the kitchen, the faster it fills. We’ll suggest an interval after the first clean.
What’s TR19?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not law, but it’s the benchmark.
Leave it or put it right?
Pouring hot water or chemicals down a slow drain is a common quick fix. It just shifts the grease further along to set somewhere harder to reach. The lasting fix starts with the trap. In Harrow, as across London, ductwork often passes through shared risers and other people’s space.
Several systems or sites on one quote often makes better use of the time. Mention every system or site you need covered, and you’ll get one fixed quote.
