So the clocks went forward and I've never bothered to work out the 
settings in my grandstream phones - until now!

If you have a Grandstream device & it's got the wrong time on it this 
morning, then you need to go into the web interface and set

Timezone:
   GMT (London, etc.)

Daylight Savings
   ON,

and change the Optional Rule to:
   3,3,7,1,0;10,4,7,2,0;60

Which I'm interpreting as:

    3: March
    3: 3rd ...
    7: Sunday
    1: 1 AM
    0: 0 minutes

then

    10: October
     4: 4th ..
     7: Sunday
     2: 2 AM
     0: 0 minutes.

and +60 minutes.

someone correct me if I've goofed!

If in the UK and you need a timeserver, use uk.pool.ntp.org.
