No bonding = no mains change.

Check out ESC guidance on CU upgrades, and reg 131.8 off the top of my head.

If the customer won't have the 'Bonding' installed/renewed, then you don't do the board change - simple as.

6. Main earthing and bonding and
meter tails
6.1. The installer must verify, as a minimum, that:
a) the main earthing terminal of the installation is
connected to an adequate means of earthing
via a suitably sized earthing conductor,
b) the main protective bonding is adequate, and
c) the meter tails and the distributor’s equipment
have adequate current-carrying capacity.
Note. Some electricity distributors have requirements regarding
the earthing conductor, main bonding conductors and meter
tails that exceed the requirements of BS 7671.
6.2. If any of conditions 6.1 (a), (b) or (c) is not met, the
customer should be informed that upgrading is required.
If the customer refuses, the installer should not proceed with the replacement of the consumer unit.​
