Hi Steffi2212,
Congratulations when you take the first step to move in together, you will probably save money on the travelling, you have been doing. I would shop around on the Gas, Electricity, to get the best deal, the water will basically be with one Company so there are no choices of best deals here, they will be able to tell you how to keep your water bill down, for your phone bill try Tiscali, I pay, if they still do this offer 19.99, for the phoneline, phone calls anytime free on 01 and 02 numbers, and I also get Broadband, and just 1 bill, which is online for all these services. And for 0845 numbers and 0870 numbers try and look on the internet for WWW.SAYNOTO0870.COM, not all the numbers are free but I now have some choices. For the TV I have Sky or get a freeserve box about 40.00 there are cheaper and you can update the package. Eventually you maybe able to save for a deposit, some Companies will pay the deposit of 5%, you could asks Barratts homes or Wimpey, they used to do this, or try for a Housing Association house where you have a share of the property, and can eventually buy the other half of the house. These are things you could look into maybe in the future.
