About our grease trap cleaning in Farnham
A clean trap means flowing drains and no foul smells. The fat, oil, grease and solids are taken out and the chambers and baffles cleaned and the trap checked before we leave. Typical jobs include drains that gurgle and bubble and a bad smell from the sinks or drains, across inline grease traps, pot wash sinks and school and care home kitchens.
Rural kitchens may drain to a septic tank or a private drain rather than straight into a public sewer, and fat getting past a grease trap can cause real trouble there.
The report is your system’s health record: dated, with pictures, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

How the visit works
We are used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. The visit itself takes less than an hour for many under-sink units. Somewhere like Farnham, lanes, gates and parking are worth mentioning in advance.
- First, we find the trap and look at its connections.
- We make sure nothing drains into the trap.
- We empty out the fat, oil, grease and solids.
- We clean every part of the inside.
- We refit it, run water through and remove the waste.
Preparing for the visit
- Mention any sign-in, permit or induction we need
- Let us know about parking and loading
- Make sure someone can let us in and lock up afterwards
How to get 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.
Advice
Grease trap cleaning in Farnham: local notes
The FSA’s data shows about 3 bars, pubs and nightclubs registered within 1.5 miles or so of the middle of Farnham. Any of them serving food has a kitchen that collects grease out of sight and drains that need protecting. It’s Uttlesford council that sends environmental health officers to food businesses in Farnham. Grease behind equipment or on a ceiling is the kind of thing an inspection can note. Photos and dates from each deep clean make a useful record.
Hall and church kitchens, near Church of St Mary the Virgin or anywhere around Farnham, are used by many hands, and periodic deep cleans and grease trap visits keep them in order. For schools such as Farnham Church of England Primary School, deep cleans and grease trap work are normally booked for the holidays.

Multi-site and managed buildings
Multi-site operators often want one contractor and one number. We work across London and the South East, so a run of sites can go into one programme and kept to a regular schedule.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
Staff cleaning versus specialist work
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
When to call us in Farnham
In Farnham, as everywhere, grease traps are easy to forget. Hidden under a sink or in a floor, it’s often ignored until something goes wrong.
If you notice any of these, it’s worth a diagnosis:
- A larger grease trap that needs emptying
- A routine grease trap service
- Drains that gurgle and bubble
- A bad smell from the sinks or drains
Healthcare kitchens, like those at hospitals such as Herts and Essex Hospital (about 2.8 miles south-east), cook for long hours, so deep cleans and grease trap work are planned around patients’ meals.

How we price grease trap cleaning
Every site gets its own quote. This is what makes a difference:
- The times the site is available
- Access, including roofs, risers and ceiling voids
- Whether several sites go on one quote
- The scale of the work
When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account and give you a fixed price before any work starts.
What we need to know
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- Detail shots of panels, filters and grilles
- Any symptoms, from odd noises to smells or leaks
- Wide photos of the system and the area around it
- Your opening hours and when the area is out of use
For grease trap cleaning in Farnham, give us a ring on 0345 646 2711, or email photos. Let us know the site type and the opening hours, and send photos or your last report if you can. We typically send a fixed quote within one working day.
What the work involves, part by part
School, care home and staff kitchens
In schools, grease traps can be cleaned when the kitchen is closed or between meal services.
Inline grease traps
Several sinks may drain into one inline trap. More waste means faster filling.
Why deal with it now?
A dirty grease trap smells. Rotting food and grease give off foul odours and the smell carries. Cleaning it removes the cause. In a place like Farnham, ductwork and fans are easy to forget until something goes wrong.
A single site or a whole portfolio, we price it on the same basis: the work involved, the access and the timing. The price is fixed before work begins.
