What the work can include
New consumer unit with RCD/RCBO protection
The quote should state the preparation, protection, disposal and making-good included, not just the visible repair itself.
Earthing and bonding checks
The inspection identifies access constraints, hidden defects and the information a tradesperson needs to price the work without avoidable provisional allowances.
Testing, labelling and certification
Testing is documented at handover so you know what was checked, what standards apply and which certificates or maintenance notes you should retain.
How to compare quotations
Existing board condition
Ask what the inspection covers, which hidden conditions could change the price and how any additional work must be approved.
Number and condition of circuits
Ask what the inspection covers, which hidden conditions could change the price and how any additional work must be approved.
Earthing arrangement
Ask the tradesperson to define this allowance, its exclusions and the evidence they will provide at handover so every quote can be compared fairly.
Surge protection and future circuits
Ask the tradesperson to define this allowance, its exclusions and the evidence they will provide at handover so every quote can be compared fairly.
Questions homeowners ask
Do I need a new consumer unit?
Age alone is not decisive, but missing protection, damage or alterations can justify an upgrade after inspection.
Will the power be off?
Yes. Arrange a suitable window and protect sensitive equipment before the supply is isolated.
Is RCBO protection worth considering?
Individual RCBOs can reduce nuisance tripping and make fault finding clearer; ask for the options in the quote.
