Halifax on-line share dealing service is pretty good, service-wise. Not only "instant" dealing, but also provides all reporting services and analyses needed, incl option to print share dividend certificates for tax purposes.
first of all go and ask to your bank whether they provide facility of online share dealing. If yes open your account with them as you are very much familiar with them. If not then you can open your account under any private bank as there service is very nice an up to the mark. But before that do a proper research of the market to get the best deal.
Hi,
Your bank is always one of the best choice you can make.
Lepers you can also consider opening up a "demo" account on the various sites to get a first hand knowledge of the share market.
