Consumer Unit Replacement
Fuse-box and consumer-unit upgrades for homes
A consumer unit is the distribution point that protects and controls a home's electrical circuits.
Replacement can improve protection and circuit identification, but it should be recommended from condition, suitability and planned use rather than age alone.
B2E Electrical & Renewables Ltd is a family-run SELECT member based in Rosyth, supporting homeowners, landlords, property buyers, property sellers, letting agents and residential developers across Fife and surrounding areas.

What Consumer Unit Replacement Includes
Homeowners seeking fuse-box or consumer-unit replacement.
The exact scope depends on the existing installation, the property or site conditions and the customer-safe information confirmed before work begins.
- Old fuse-box review
- Existing circuit checks
- RCD or RCBO protection
- Surge protection where appropriate
- Earthing and bonding assessment
- Inspection, testing and labelling
A new consumer unit must not hide existing faults. Faulty circuits need investigation before being placed back into service.
Why the service may be needed
Unsuitable old equipment
Older boards may lack suitable protection or capacity for the property.
New electrical demand
Kitchens, EV chargers, solar equipment or new circuits may require a board review.
Inspection findings
An EICR can identify protection, enclosure or labelling issues that need correction.
When to consider replacement
A consumer-unit assessment is sensible before major electrical changes or where the board is clearly unsuitable.
- Frequent tripping
- Poor circuit labels
- Damaged enclosure
- New circuits planned
- No recent inspection history
- Older fuse carriers
A new consumer unit must not hide existing faults. Faulty circuits need investigation before being placed back into service.
Replacement options
RCBO arrangements
Individual circuit protection can improve fault separation.
Surge protection
Surge protection is considered where appropriate for the property and equipment.
Replacement versus rewire
Damaged or unsuitable circuits may need remedial wiring rather than only a new board.
How We Complete Consumer Unit Replacement
Each consumer unit replacement project has a service-specific scope, with more detail available in our shared electrical project process.
Step 1
Initial discussion
We confirm the domestic requirement, who the work affects and the practical reason for the enquiry.
Step 2
Site assessment
The existing installation, access, likely cable routes and any constraints are reviewed before the scope is finalised.
Step 3
Scope and quotation
The quotation describes the agreed consumer unit replacement scope, known assumptions and exclusions.
Step 4
Planning and access
Dates, isolations, access arrangements and coordination with other trades or site users are agreed before work starts.
Step 5
Installation
The work is completed with attention to circuit condition, protective-device choice, safe isolation, neat installation, labelling and certification.
Step 6
Inspection and testing
New or altered electrical work is inspected and tested where required before handover.
Step 7
Certification and handover
Appropriate certification, labels, records and operating information are provided for the work within scope.
Regulations, Safety and Scope
Designed, installed, inspected and tested to the current edition of BS 7671 and applicable Scottish Building Standards requirements.
Earthing, bonding, circuit protection, cable routes and certification are reviewed where they affect the agreed work.
Benefits of Consumer Unit Replacement
Better fault separation
Correctly selected protection can make future faults easier to identify.
Clearer circuit schedules
Labelling helps owners understand the installation.
Safer future additions
A properly assessed board gives a better base for later electrical work.

Consumer Unit Replacement Questions and Answers
Does every old fuse box need replaced?
No. Age alone does not prove replacement is required; the installation should be assessed first.
Will a new consumer unit fix every fault?
No. It can reveal existing faults that then need diagnosis and repair.
Will I receive certification?
Yes. Appropriate inspection, testing and certification are completed for the work carried out.
