Modern consumer units installed to current standards — RCD protection, metal enclosures, spare capacity for the future, and the existing installation tested before anything is energised.
The consumer unit is the control centre of your electrical installation and the thing standing between a fault and a fire or a shock. Older boards — particularly rewireable fuse boxes and early plastic units without RCD protection — simply do not offer the protection modern standards require.
DTF Electrical install modern consumer units across Liverpool, Kirkby and Merseyside for homes and commercial premises.
An RCD detects current leaking to earth — usually through a person — and cuts the supply in milliseconds. It is the difference between a shock and a fatality, and older boards often have none at all.
A board change is not just swapping a box. Before a new unit can be safely energised, the existing installation has to be tested — because a modern board with sensitive protection will immediately reveal faults an old fuse box tolerated for years.

We also install and upgrade three-phase distribution boards and sub-mains in commercial and industrial premises.
See commercial electrical contracting for distribution work at scale.
If you are unsure whether a board change is what you actually need, an EICR will establish the condition of the whole installation.
Common Questions
Most take between four and six hours. Older installations sometimes need remedial work before a new board can be safely energised, which can extend it.
Sometimes, but not always. If there is an underlying fault on a circuit, a new board with more sensitive protection may actually trip more readily. We test to establish the cause before recommending a board change.
A rewire includes a new consumer unit as standard, so no.
A Residual Current Device monitors for current leaking to earth and disconnects the supply in milliseconds. It is the single most effective protection against fatal electric shock.
