If this is going to be a regular thing or you are hoping for more, and bigger jobs I suggest you get them done professionally.
The legislation is changing all of the time and using a template may not cover you.
I had mine professionally produced and have them reveiwed regularly... saves me the hassle and make sure I comply with all current legislation at all times.
If your documents are not up to date, you may find problems with your insurance if you ever have to claim.
These guys do mine and they are great
