Lowering springs on 100k NC, should I do shocks too??

Have an NC that’s now covered 100k miles but in fabulous condition. 

Have a set of OEM Eibach lowering springs and have 2 questions;

Should I replace shocks too?

Where is best to get work done?

Live in Telford, Shropshire but work in Tamworth so need a local specialist to do the work and do full alignment after.

All opinions most welcome. 

Maybe but the cost of springs and shocks is wandering into Coilover Country.

I think 100k on a set of shocks is pretty good!
