In reply to Mountain Spirit:
One thing you should look into is around securing personal safety working in other people's homes (both yours and your clients)
For example you are assisting your client with body position by physically moving them for example by holding their hips.
This of course is entirely innocent, but could open you up to accusations of sexual assualt/touching, and without evidence could be difficult to prove what was actually happening.
In fact doing anything 1 on 1 makes it your word against theirs.
Therefore consider things like videoing sessions (with consent of course) ostensibly for the purpose of allowing you to show your clients where their positions are wrong/improving etc, but with a secondary purpose that you have evidence of what actually took place.
Equally you could put yourself in a position where you feel threatened and/or vulnerable (imagine a jealous boyfriend/husband having a go because they thought they saw you touching up their missus etc) - using things like check-in/check-out services so there is always a trail of where you are/should be (This could be as simple as always remembering to text a mate: "Going to no.17 GU1 1DB expect to leave at 16:00" "Left no. 17 Gu1 1DB at 15:50 on route to next job 34 GU4 5FR" etc.)
Don't get me wrong, these sort of issues are few and far between, however they can be serious when they do happen and its always good to have a plan just in case or at least be aware of the danger so can quickly take mitigating action.
