Hi Takara,
I just wanted to let you know that there is a UK board, under 'UK Tax Discussion', which may be helpful. Someone there may have good knowledge of Reading.
There is a UK-based money saving website called 'moneysavingexpert.com'. It's a little bit commercial, but it may be a good place to start your research. If you're setting up home here in the UK, you may want to check out their recommendations for utilities, insurance and telephone/broadband, etc., for the best deals.
If you are making any big purchases for your new home, it may be worth seeing if you can get cashback from a website such as 'topcashback.co.uk' or 'quidco.com'. You can also search for vouchers or coupons online to get discounts from online retailers.
As for major supermarkets in the UK, I would say that Aldi and Lidl are probably the cheapest, followed by Asda, Morrisons, Tesco and Sainsburys.
For investing/saving in the UK, you may want to check out Stocks and Shares or Cash ISAs (ISA - individual savings account); adults can currently invest or save £20,000 per tax year into these accounts, and the returns are tax-free.
If you're interested in UK retirement accounts, you may want to check out SIPPs (Self-Invested Personal Pensions).
With regard to property taxes, we pay something called 'Council Tax'; it is typically based on the value of your house. Houses in 'Band A' have the cheapest council tax, whereas houses in 'Band F' have the most expensive council tax. See
www.gov.uk/council-tax-bands. I think your water and sewerage bill, billed by your water supplier, is also based on these bands.
See here for 'Car tax', known as Vehicle Excise Duty (VED):
www.moneyadviceservice.org.uk/en/articles/car-tax-bands-explained. Typically, the more environmentally friendly your car is, the less 'Car tax' you pay per year. In general, you would also pay less to insure such cars, which are typically small with small engines.
Wishing you all the very best for your move to the UK.
