This guide explains the main points to consider before speaking to an electrician. It is general information rather than a diagnosis of a particular installation.
The unit is only part of the job
Cost includes appropriate protective devices, installation, circuit identification, inspection, testing and documentation. The number and condition of existing circuits influence the specification.
Why pre-testing matters
A new consumer unit can reveal faults that older protection did not detect. Pre-testing helps identify likely remedial work and reduces surprises during replacement.
Questions to ask
Confirm the proposed protection, whether surge protection is included, how existing defects are handled and what certification will be supplied.
When to speak to an electrician
If the issue involves heat, smoke, burning smells, visible damage, exposed live parts or protection that trips repeatedly, stop using the affected equipment and seek professional advice promptly. Do not remove covers or bypass protective devices.
Getting a clear next step
Share the property type, postcode, symptoms or planned result and any useful photographs. A focused description helps establish whether advice, an inspection, fault finding or a quotation visit is the right next step.
Consumer unit replacement
Modern fuse board upgrades with careful testing and clear certification.
