Commercial Drain Cleaning in Isleworth: Advice & Costs
For a business, drain cleaning is continuity planning: one backed-up kitchen or flooded floor costs more in lost trade than a year of planned jetting.
What commercial cleaning involves
- High-pressure water jetting of foul and surface water runs
- Descaling and fat removal from kitchen drainage
- Gully, interceptor and grease trap emptying/cleaning
- A condition note flagging anything that needs repair
Food premises and grease
Fat, oil and grease are the number one cause of commercial blockages, and discharging them to sewer beyond consented levels can breach the water company's trade rules. Planned jetting plus a maintained grease trap is the standard compliant setup.
Building the schedule from risk
Frequency follows fat and footfall: a busy kitchen turning covers all day sits at quarterly; lighter catering, twice-yearly; offices with staff kitchens, annually with gully checks. Start one notch cautious, let the first year’s camera stills justify reducing it — evidence-based maintenance is cheaper than either extreme.
Grease traps: the essentials
Size to the kitchen’s flow, not the cupboard space. Service on a schedule the waste carrier documents. And treat the trap as protecting your consent, not just your pipes — because that is how the water company views it.
Waste, carriers and the paperwork your auditor expects
What leaves your drains is legally waste, and the paperwork follows it: tankered grease and silt travel with waste transfer documentation from a registered carrier, and your duty of care is discharged by keeping those notes on file. FM audits, environmental inspections and insurance claims all reach for the same folder, so make its assembly a contract condition: every visit produces its note, every note reaches the file. Contractors who handle compliant disposal daily provide this without being asked twice.

Common questions
How often should a restaurant jet its drains?
Quarterly is the common baseline for busy kitchens; lighter use stretches to twice-yearly. Contractors will quote a schedule against your fat load.
Can cleaning happen out of hours?
Yes — say so in the job post. Out-of-hours work carries a premium but avoids closing during service.
Landlord or tenant responsibility?
Whatever the lease says — commonly the tenant maintains, the landlord owns structure. Check before commissioning recurring work.
What do environmental health actually check?
Evidence of management: the trap service log, the jetting schedule, no fat sheen at the gully. Poor records invite closer inspection.
Tenant or FM company — who holds the contract?
Whoever the lease makes responsible for maintenance — commonly the tenant for their demise. What matters is one named holder; problems arise when responsibility is split between two.
