Mark, wait until September to sow grass seed...the ideal time
if you dont mind bare soil you can prepare for it now though
trench in your grass .....scoop off top 1 or 2" and place upside down in shallow trench. remove large stones and roots as you see them. If you can add a couple of inches of good top soil it would help. Then the (relatively) hard bit.....raking and levelling. Take your time over this. Level by walking on your heels not with a roller. Then rake. Then tread again. Very satisfying at this stage as you develop a fine tilth and firm level surface. The more times you rake and tread the better.
come September lightly scatter fertiliser and rake it in. Then sow your seed. half one way and lighly rake it iin then half of the seed in the opposite direction and rake it in. Keep moist until it germinates...usually a couple of weeks.....and until it is a couple of inches high, when you can mow
