OK service done...Started at 8:30 finished at 14:00. Changed the plugs (the ones that came out were badly burnt out!), belts, front pads, oil filter, engine gear and diff oil, cleared out the washer water lines which were blocked. Also found some oil in the 5th spark plug chamber, cleaned it out but needs fixing at some point, put in some oil leak fix fluid as well.
Cleaned up various other parts, in 5 hours a good job done and car is definitely running much smoother.
