The questions we get
How much does grease trap cleaning cost?
Typically £100–£300 per visit in 2026 quotes, depending on trap size and access: small under-sink traps at the bottom of the range, tankered external below-ground tanks at the top. Scheduled contract visits price below one-off callouts, and emergencies above.
How often should a grease trap be serviced?
Busy commercial kitchens commonly go every 1–3 months, heavy-frying sites more often, quieter kitchens less. No statute sets an interval: throughput decides, and the working rule is to empty the trap before grease and solids reach about a quarter of its depth.
Do commercial kitchens legally need a grease trap?
Section 111 of the Water Industry Act 1991 makes it an offence to discharge matter that interferes with the free flow of sewers, and Building Regulations Part H expects hot food premises to have adequate grease separation, with BS EN 1825 the standard for sizing and maintaining separators. A working trap is the practical way to comply with both.
What happens to the waste after a grease trap clean?
It leaves as controlled waste with a registered waste carrier, and you should be given a waste transfer note for every collection. Keep the notes with your service records: they are your duty-of-care evidence if the water company or environmental health ever asks.
Do enzyme dosing or bacteria treatments replace cleaning?
No. Dosing products can help manage odour and slow build-up in some setups, but they do not remove the accumulating fat and solids, and water companies do not accept dosing as a substitute for emptying. Treat them as a possible supplement to a service schedule, never a replacement.
Is this quote service really free?
Yes, free to you, with no obligation to accept any quote. We pass your details only to relevant local grease trap cleaning companies, who quote you directly; we may receive a fee from those providers, which is how the service is funded.
