Thank you for agreeing to take part in my very exciting research project. I estimate that the survey should take 10 minutes to complete if you are able to do a quick bit of preparation work in advance of starting to answer the questions.
To help streamline the survey process, if you are able, it would be a good idea, if you have paper bills, to gather up your last years worth of electricity and water bills. If you receive your bills electronically then perhaps locate them in your inbox or download these to your desktop.
If you can't be bothered doing either of these two options, then do not despair, there is an option at the end of the survey for you to provide your permission for me to access this information directly from your energy and water retailer.
