An older fuse box or consumer unit does not automatically mean immediate replacement, but it can be a poor
base for extra electrical work, repeated fault resets or future upgrades. Photos and context usually show
whether the next step is a scope review, fault finding, an EICR or a replacement quote.
Why older boards get reviewed
- Protection may be limited compared with a modern board.
- Labels, circuit layout or previous additions may be unclear.
-
The board may already have been flagged before renovation, sale, tenancy or wider electrical work.
What can change the next step
- Repeated trips may need diagnosis before replacement is considered.
- Visible damage, heat marks or poor previous work can widen the scope.
-
If a formal condition picture is needed first, an EICR may be more useful than guessing from age
alone.
