The UK Shareholders Association (UKSA) is a private organisation that promotes the importance of individual shareholders, conducts periodic campaigns to correct specific injustices, has growing influence and deserves support. It is independent of all conflicts of interest and funded entirely by membership fees and individual donations.
Sharesoc is a sister organisation of UKSA, with a greater focus on the skilled private investor and active campaigning on specific corporate misdemeanours.
Government bodies have a number of different advice services of varying quality, due to be consolidated into a single service in 2020 under the name 'Money and Pensions Advice'. Currently the most relevant sites are Money Advice Service and Pensions Advisory Service.

HM Revenue and Customs (HMRC) is the horse's mouth for any tax regulations.
Martin Lewis at MoneySavingExpert has the pre-eminent independent site covering basic money management skills, with much practical advice and information.
