GSM Officialdom (banks, pension providers, DWP, Land Registry and the Probate Registry etc) will insist on seeing a Deed Poll.
I didn't have to have a Deed Poll because I reverted to my maiden name and had my Birth Certificate to prove it. I was told I only needed a Deed Poll if I decided on a completely different name.
I didn't need a deed poll either, so maybe it is easier if reverting back to one's maiden name. I changed my name to my maiden name for my passport as starters, and then used my passport as an identifier when changing my name for banks, land registry etc. I did keep my divorce papers handy, but I don't recall ever having to produce them
