I'm the same as the rest of the UK ones, just boil the kettle, put the tea bag in the mug, pour boiling water on it, let it brew for a minute then take it out, add milk. I like my tea quite weak, so I have quite a bit of milk.
I also have fresh tea for one of those one cup teapots but don't use that very often.
I think posh tea making in britain is a thing of the past though you can get posh tea bags with a much better quality of tea such as twinnings.
I'm sure though there are some folks in britain (like the queen) who have it done in a very posh manner, with fresh tea that costs loads.
