I can see you ask about satisfaction with life overall and about friends and social networks - are these the only wellbeing questions you are asking?
I have recently found about 'The Short Warwick-Edinburgh Mental Well-being Scale' (SWEMWBS) and I wondered if you are using these items in your survey or plan to in the future?
You have a section for neighbourhood with with no question - is that a gap at the moment?
Do you have any background information regarding the environment questions (leaving tap running and TV on standby) - did you do some research that suggested these were good indicators of environmental attitudes?
Also, do you produce statistical releases in the form of spreadsheets and do you have a large enough sample size for us to have information at county-level?
