Where does the 'Britain is full' stuff come from. We are not the most densely populated place in the world (Singapore, Hong Kong have 20 times more people per sq.km) nor the most populated place in Europe (Holland and Belgium have more people per sq.kl. Parts of the UK - around the major conurbations are more densely populated - but much of Scotland and Wales are very low density. Economic policies to spread people around more would help.
