I wrote the lock document and have PMed you.
You solicitor will do the water and elec. contracts at a fee of course, you may need to be in on the day the elec. is turned on because they normally need to fit the main breaker - half hour or so.
If you do it yourself I don't know but.....
Endesa the elec. co. have an English speaking telephone service, but for water you would have to go into the Agua office in the main street of Manilva, I have seen people getting their contract done there. The speak some English.
Suggest you write a note in English saying what you need and translate using Google or Babelfish and print off and take in.
