New laptop keys

[#1]

Does anyone know where to get new keys for a laptop in the UK. They are those separate keys with a hinge mechanism and 3 will not stay on. Fix appears quite simple but I'm struggling with finding a supplier in the UK. 

The laptop is an hp pavilion 15 - eh0507sa

Thanks

Thanks. Found those but the keys I need are always out of stock. All other vendors I can find are either in us or Europe. There's got to be some shops in the UK 😞
