Nicola, Did you lay the lawn or is it new build. If new build they would lay general purpose rolls on thin soil over often clay or rubble and all the above tips would help. If you laid it did you use too fine a mix and also did you scarify the lawn in Autumn.
If a new build then you need to build up the soil and check drainage, Using a rake go over the lawn lifting any moss or detritus from the top, you will be surprised at what comes off and it can go in the compost bin. Now you need to aerate the lawn with a garden fork pushing the fork into the lawn every few inches, mark the lawn with canes laid out so you know where you have been. You can use a hand Aerator which will remove divets or hire a machine from the DIY shop for a day, that will also remove divets. Now you need a bag of washed sand and one of compost which you may need to riddle then mix the two and scatter on the lawn, using a stiff brush to sweep the mix across the lawn filling the holes, that will allow aeration and drainage as well as feeding the grass roots. I would also use a winter weed and feed though some people prefer not to do that, it is personal choice. leave until spring then cut with the blades up, most people take far too much off the lawn, it needs some grass length to help feed the roots. A spring feed and weed will also help. Hope this helps
