AS above. If the wiring is in a serviceable condition then it will only need to be the consumer unit that is changed plus upgrading to the earthing. So not that much upheaval.
If the wiring needs replacing then you can expect floors to be taken up, walls chased out, tiles taken off, redecorating and making good on a large scale.
The only way to find out is to have a qualified electrician do a full test and report on the installation (EICR). Then you'll know what you are in for.

As previous post have mentioned an EICR (electrical installation condition report). This will flag up most issues and recommendation on any remedial work or updates required. Only then will know what upheaval will be required as not all installation are suitable for a straight swap over and a EICR would help identify any inherent issues and hopefully prevent any attributed power loss in the future.
The EICR will require access to the existing fuse board, the metering, the earthing conductor, main earth bonding clamps, any supplementary bonding, switches, sockets, light fittings, outlet plates, isolators, fused connections, accessible joint/junctions etc.... So would be very helpful to the electrician if you are familiar with the positioning of these and they are accessible.
Also as your existing wiring to the existing fuse board could well short in length and require extending, sometimes this can be done within the new board, sometimes external of the new board or sometimes if more practicable a new length fitted and don't rule out the need for new tails, earthing conductor and main earth bonding to be updated.

In that case the wiring itself should be in good condition, and won't need replacing.
However, there could be things that need upgrading, checking etc. There may be a few bodged alterations that have been done in the past, so it would be sensible to get the place inspected.
But the short answer is; you shouldn't need a re-wire.
