It's a ballache "just using it". I've never considered the deed poll route though.
I use the shortened version of my first name and so a load of records (birth certificate, NHS) use the full first name, most of everything else (passport, driving license, bank, work, etc) uses the shortened version.
I have to jump through hoops for various things:
I have to admit to an alias on DBS checks (for work and for volunteering with kids sports clubs)
Covid time was sometimes tricky as NHS vaccination records wouldn't match my passport name (some countries had automated systems so I was booted into the slower manual process)
