First of All Hello im new to this forum,
Im planning on installing a 9.8kw elec shower, please can you guys help me on the elecs side of things.
We certainly can, but first you should understand the legal position you are in regarding this work.
Here is the most recent version of my ongoing summary of DIY electrical work and the law, it contains links to legislation etc that you should
follow and read:

Then you should get some reference material which will help you to adhere to the wiring regulations. This link has a list:

From your question I'd say you probably need the first one, but if not you should get #s 2 - 4 - they should be on the shelf of anybody who wants to work on their electrics.
Both of these are needed. There's some background material on types of MCB here, if you're interested.

cable size , etc, etc.
also rating of fuses, pull switches etc...
You should read this
//www.diynot.com/forums/viewtopic.php?p=81696#81696 to understand the relationship between load, cable size, MCB rating etc.
Also, this site has some very useful information:

While you wait for your copy of the Electricians Guide to arrive, you can get a head start by reading about the factors that affect cable capacities here:
http://www.tlc-direct.co.uk/Book/4.3.1.htm
And here are a couple of useful on-line calculators for cable sizing:

i have not ever done this before, but am a competent diy'er, but with instructions on the elec side i should be ok.
You should only do it with a firm understanding of everything involved - it's not a task you should undertake on the basis of following instructions but not knowing why you are doing things.
The bathroom is at the top of stairs and meter is at the bottom, can i run the cable straight up into loft along frame and down into bathroom rather chasing into walls or pulling up first floor??
Difficult to say without being there, but exposed cables are a bit naff.
The link above to the Electricians Guide will tell you about grouping and insulation factors, which may affect you, and you should also make yourself familiar with the rules on concealed cables:

Emphasisg on how to connect to electrical suppy and what changes i need would be a great help, any questions in order for you to give better instructions please fire away,
You also need to learn about bathroom zones:

and what is required in terms of equipotential bonding:
