Understanding commercial gas safety certificate cost in London helps you budget for compliance without surprise extras. Price follows appliance count, location, gas type and whether defects need repair on the day.
What is included from £150
Our advertised from £150 covers a standard commercial or catering inspection visit within normal service areas, safety tests and issuance when the installation passes. Travel to outer boroughs or large multi-kitchen sites may be quoted individually.
Extra costs to plan for
- Replacement hoses, regulators or thermocouples
- Interlock repairs or fan motor issues
- Additional appliances added since last year
- Out-of-hours or same-day surcharges
- Second visit after remedial work
Comparing quotes fairly
Ask whether the quote includes all appliances, parking, and certificate issue. Confirm the engineer’s Gas Safe categories. Lowest price is not lowest cost if you pay twice after a failed inspection.
