Have power to my Triton T80si fed through Mineral Insulated
Copper-Sheathed cable, some 8 metres from fuse box. This was installed
prior to buying the flat last year. After some redecoration work and
removing old hot air (no longer used )central heating ducting I now
find myself with surplus cabling that needs re-routing and shortening
by approx. 1 metre.
Problems would like help on are :
1. If I cut the cable to shorten it, how do I fit a new new seal and
where do I buy from?

From a wholesaler who stocks them - and not all do.

2. Is it a DIY job or is a professional electrician needed?

Difficult question to answer. To be safe I'll say get a pro in. I use the
stuff and have the terminating tools, and like everything else it's simple
when you know how. And the larger sizes - like you'll have - are probably
easier to terminate.
However, the other gotcha is that there will be plenty of electricians
around that don't know how to do it either.

3. Might it be OK just to loop part of the excess cable in a ducting
void and keep the original seal in tact? I would need to bore larger
holes (12mm min) in the thermalite walls for the re-routing.

That would be the easiest answer.

4. If decide to get rid of shower all together and install one to run
off the combi-boiler, can I easily remove the entire cabling from the
fuse box?

Yes - there's nothing complicated about removing it. Once disconnected,
you can cut through it with a hacksaw. You might find it interesting to
take a termination apart to see how it's done.

Thank you in advance for any help with the above.
