I am about to rewire my consumer unit (the current one is very old and
doesn't support RCD). To diy it, I think I need cut off the mains supply
first. However, I can't find any switch around the incoming mains. Should I
contact my power supplier to temporarily cut off the power during the
installation? Any suggestions and comments are very much appreicated.

Best wishes,

Bing

When I replaced the CU in my house I removed the suppliers fuse, this
involved breaking the seal. 4 years on, no problems, plenty of people have
seen the seal has been removed.
