I definitely recommend Energizer over Duracell batteries. I have had several battery leak incidents over the years using Duracell batteries, but only one ever with Energizers, and that one really was my fault (I put away a machine in a storage cabinet without realizing batteries were installed).

In US, Energizer N cells are cheap and fast from Amazon, not sure if things are the same in UK.

Also, when looking online, "N" cells are often listed as type E90 cells and adding that to a search will often yield better results.
