01
Earthing and bonding inspection concerns
An inspection observation, new equipment or a consumer-unit change can bring existing protective arrangements into focus. Keep the original wording of any report available. It is more useful than assuming that every metal pipe needs a new connection or that a visible wire proves the installation is adequate.
02
How earthing and bonding differ
Earthing and bonding have related but distinct protective roles. Earthing provides part of the intended path for fault current; protective bonding helps limit dangerous differences in potential between relevant conductive parts. They form part of an assessed system rather than isolated items that can be specified by appearance.

03
Assess protective connections before changes
The electrician needs to consider the supply arrangement, existing connections and relevant parts of the property. Some issues may involve the electricity network operator as well as work within the installation. Do not remove, move or add connections based on a general description online.
04
Coordinate earthing and bonding repairs
Where work is needed, discuss access, routes and how the resulting arrangement will be tested and recorded. Coordinate with plumbing, bathroom alterations or other building works where necessary. An agreed scope should make clear which concern is being addressed and what associated work is included.
05
Request earthing and bonding assessment
Provide the report observation, details of the planned project and any available installation records. Ask how the findings will be explained and how responsibility is divided if an issue concerns the incoming supply. This supports a quote for appropriate work rather than a guessed list of materials.
Electrical service questions
Questions about earthing and bonding
Are earthing and bonding the same thing?
No. They are related parts of electrical protection with different functions. Their suitability must be assessed as part of the installation rather than judged independently by appearance.
Does visible pipework always need new bonding?
Not necessarily. The electrician must assess what requires bonding in the actual installation. Do not assume every visible pipe needs the same treatment.
Can this work be assessed before a consumer unit replacement?
Yes. Existing protective arrangements should be considered when planning the replacement. Any associated work should be identified and explained in the proposed scope.
