About our grease trap cleaning in Leavesden
Fats, oils and grease are the main cause of blocked kitchen drains. Further on, grease can build into fatbergs in the sewer. A grease trap that’s emptied and cleaned regularly holds them back. Common call-outs are for a grease trap that hasn’t been emptied in a long time and a blocked kitchen drain caused by grease, on pot wash sinks, kitchen waste pipes and under-sink grease traps.
Kitchens around a smaller place like Leavesden are often in older buildings, with drains and grease traps that have been there for years. Smells and slow drains are the usual warning signs.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we are fully insured.

How we price grease trap cleaning
The diagnosis comes before the price. We look at:
- What state the system is in
- The times the site is available
- Any permits to work or inductions
- The number of sites or systems
The price reflects the work, not guesswork. That is why every job is surveyed first, and why the quote is fixed before any work starts.
Asking for a quote
There’s no need for technical detail. Just send:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Any symptoms, from odd noises to smells or leaks
- Any previous report or certificate
- Photos showing the whole system and its surroundings
The quickest way to a quote is to send pictures: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and we can price many jobs without a visit.
Commercial kitchens in Leavesden
Look up Leavesden on the FSA’s food hygiene register and you’ll find about 40 restaurants, cafés and works canteens and about 24 takeaways across Leavesden and its immediate surroundings (about a mile and a half). Fat from washing up sets hard in pipes, and kitchens like these produce plenty of it. In Leavesden, food businesses are inspected by environmental health officers from Three Rivers council. 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.
Healthcare kitchens cook through the year, so a deep clean has to be fitted around meals; Leavesden Hospital, about 0.6 miles north-west, is the nearest hospital to Leavesden. A summer deep clean suits schools such as Alban Wood Primary School and Nursery, as the kitchen can be stripped back with no lunches to serve.

Your questions about grease trap cleaning in Leavesden
Can a school kitchen in Leavesden be done out of term time?
Yes, and it’s the easiest time to do it. The FSA’s register shows about 23 schools and colleges with food registrations within roughly a mile and a half of Leavesden. Just give us a ring on 0345 646 2711, or send details by email with your term dates and we will plan around them.
Will you come out to Leavesden?
Yes, Leavesden is part of our area, however small the site. A survey first, from pictures or a visit, means we arrive with the right kit.
Do you clean under-sink and inline grease traps?
Under-sink units, inline traps and interceptors are all covered. Let us know what’s fitted and we’ll plan around it.
Do you provide a certificate or report?
Yes. You get a written report with photos after every visit, 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.
What does TR19 mean?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping and expects a risk-based approach.
Do you offer emergency callouts?
Yes. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we’ll talk you through the next steps.
What types of premises do you cover?
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 you tell us when the next visit is due?
Yes. The report recommends when the next visit should be, based on what we found and how the system is used.
Between visits
A little care between visits keeps the system in better shape. We recommend:
- Keep strainers in every sink
- Report slow or smelly sinks early
- Get food waste into the bin, not the sink
- Make sure the trap can be reached easily
Once the trap is cleaned and refitted, the sinks can be used right away. Water is run through to check everything flows before we go.
Grease that gets past the trap sets in the drains. Clearing it then is a bigger job so prevention is the easier route.
Why act early in Leavesden
A full grease trap lets grease through to the drains. It hardens on the pipe walls, until the drain blocks. Cleaning the trap regularly is far easier than clearing a blocked drain. A site near Leavesden that has to close at short notice is hard to cover for.
Every site is different, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all make a difference.

In-house cleaning or a specialist?
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
How the visit works
Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. All told, the work takes a short visit for a small trap and longer for an inline unit or interceptor. Visits to a place like Leavesden are planned ahead, so we arrive with what the survey says the job needs.
- A visit is booked around your service.
- The trap is opened up and checked.
- We remove the grease layer and settled solids.
- The inside, baffles and outlet are cleaned.
- We close it up, check it drains and suggest when it needs cleaning again.
Preparing for the visit
- Let us know about parking and loading
- Dig out any earlier paperwork for the system
- Allow time for equipment near the work to be turned off and cool down
How to get a quote
Quotes are quick. Send a few details and pictures, and we typically reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.

Do you need grease trap cleaning in Leavesden?
A full trap cannot hold any more grease. It goes on into the drain and the sewer beyond, where it can cause blockages.
The symptoms we’re asked about most include:
- A bad smell from the sinks or drains
- Sinks that drain slowly
- A small trap that fills too quickly
- Drains clogged with fat
Hall and church kitchens, near Church of All Saints or anywhere around Leavesden, are used by many hands, and periodic deep cleans and grease trap visits keep them in order.
