For me personally there is no way I would use a small one person tent on a week long trip; when raining its like being stuck in a coffin... and it does rain in the UK lol.

Look for a two person tent, often little difference in pack size and weight and you will love the extra space. If you can stretch your budget take a look at https://www.tarptent.com/double-moment.html and their range of tents, a friend now has a tent off them and loves the design and build quality.
