finally had enough of the shower dripping. After following the maintenance instructions I am left with the thought that the flow valve might just have worn out and need to be replaced as it still leaks.
So first question, I believe that the shower is

Are spares likely to be available? I can't see anything on the website, but the possible bit is trade only.
If spares aren't available, it appears that fitting a new mixer is fairly simple, as long as the centres are about the same size, which appears to be generally c150mm, would that be about right?
centres are normally standard at 150mm. Usually pretty simple to change - screw the chrome covers away from the wail and you should see the unions. Look for isolator valves so you don't have to turn everything off
I'm pretty much a DIY idiot and I managed this last month, I swapped an old bar mixer for a new Mira unit from screwfix.
The only thing I'd look for is to check the current pipe fittings stick out around 25mm (apparently they're meant to?) and check the fittings O/D 15mm/22mm etc you have will fit connect to the new ones.
My pipes were flush to the tile, and I had to fit some odd sized connector meaning numerous trips to B&Q, but it was sorted withing the weekend.
Most mixers suit 150 but are adjustable anyway
I found a replacement thermostatic valve on eBay for £18 for a fancy and expensive bar shower and it's fine. Some thermostatic showers need hot water on the left, some on the right. You have to get this right or you'll get scalded.

No they dont. The standard in this country is: Hot on left an cold on right. If your hot and cold are not like this, the plumbing has not been fitted to the common UK standard . These standards greatly help conformity and also provide consistency for visually impaired users.
Although the Water Supply (Water Fittings) Regulations do not specify which side the hot and cold should be on, all of their illustrations show hot on the left. Also for the purposes of manufacturers, it makes sense to adhere to the historically adopted British standard of hot on left.
Not that this has any bearing on what you're doing but just wanted to clear up this point.
just for any google searches.
Got hold of the spare, and it said it was the right thing, but it wasn't, it threaded into the locking thread but not the control valve thread, looks like at some point the shower model has been tweaked. But anyway on closer inspection it appeared that the thread holding the flow control valve had cracked, so it would leak regardless?
Quick trip to B&Q at 8pm, and the purchase of a Mira unit that they had in stock.
Couple of points, the centres were fine but the new cover plates were far deeper and would have meant removing the fixtures from the wall and replacing. At 8pm I am not going down that route. So reuse the cover plates the existing fittings and everything appears to be working fine. 15mins work.
