Unmetered water when bans kick in

I agree a meter would be cheaper and yes I can have one fitted, just prefer having a fixed cost and find it easier to budget with no nasty surprises.

Would have been nice that for the months the bans were in place there would have been a universal reduction in the monthly charge as £80 does buy alot of water / sewage per month looking at metered charges. 

Your username seems completely wrong, given this approach. On a metered supply you will pay a fixed DD each month, which represents one twelfth of your annual usage. No surprises, the same to budget, just much cheaper than RV billing. 
Your expectation of a reduction during a hosepipe ban is ridiculous. You can still use as much water as you want, you just can't deliver it via a hosepipe.
Get a meter and then revert io RV billing in the first 12m if you aren't saving money. It's a no-brainer.
