Why Are Gas Safety Certificate Costs Higher in Central London?
Central London properties are very different from properties in outer London areas. Many buildings are older, access is limited, and parking restrictions are common.
Typical Central London challenges include:
- Older boilers and pipework
- Flats with restricted access
- Listed or converted buildings
- Congestion charge and parking issues
- Higher appliance usage in rentals and businesses
Because of this, inspections often take more time and experience, which directly affects pricing.
What Is a Gas Safety Certificate and Who Needs One?
A Gas Safety Certificate in Central London is issued after a Gas Safe registered engineer checks gas appliances, pipework, flues, and ventilation.
Domestic Gas Safety Certificate (CP12)
Landlords must have a valid CP12 certificate every 12 months for:
- Flats
- Houses
- HMOs
- Rental properties
This certificate confirms that gas appliances are safe for tenants.
Commercial Gas Safety Certificates
Businesses using gas require commercial certification, such as:
- CP42 for restaurants and takeaways
- Commercial boiler certificates
- Plant room inspections
Commercial inspections follow stricter rules and must be carried out by engineers with commercial Gas Safe categories.

Hidden Costs Many Landlords and Businesses Don’t Expect

Commercial Ventilation Issues
A malfunctioning extraction/interlock system within commercial kitchens may result in an immediate shutdown of the gas supply.
Missed Appointments
Restricted access in Central London can result in re-visit charges should the engineers have problems with access.

- Appliances are smaller

This is why commercial gas safety certificates cost more and require specialist engineers.
