Check the companies house website or call them re the UK address. Imagine you would need one if you want to register with them. They are the best people to ask tho.
We used a company formation agent, didn't cost very much. Business link were not much help, and stopped our meetings halfway thru setting up our business as there was no more funding available. In fact the marketing advice they gave us by a so called marketing consultant was crap.
Don't have the invoice to hand as its all with the accountant at the mo, but from memory was about £70 ish?
We used a co called Freestart plc, but didn't like any of their template web designs so created our own with them. They were ok. Might be best to get one near to where you live then you could meet up with them as we found this easier than trying to describe what we needed by phone/ email.
Can you be a bit more specific about the business as I'm not sure what an "internet business" would be. Possibilities would include selling goods online, selling some sort of service online, or hosting a website where your income is generated by advertising say.
If you can be a bit more specific about the business model then you may get more assistance in the sort of thing that you need to consider in terms of structure. Company formation agents will set up a limited company but you need to decide whether a UK limited company is the best struture for your business in the first place.
depends on your business
Dh business is 'regulated' so he has to notify each appropriate regulator in each worldwide territory to conduct business there.
Can you register asa sole trader - if so, as long as you are registerde for tax etc, usually, thats all you have to do.
What country are you in?
why do you need to be a UK registered business?
Well I'd probably start with your local business link (though tricky if you're not currently in the UK). I don't think that all common or garden accoutnants will be able to handle this as you need to ensure that your busienss structure works from a tax, legal and VAT perspective in each country that you are operating in. An agency is fairly straightforward (effectively you take a commision on each let), but if you are actually buying/longterm renting properties yourself and then subletting them as holiday lets you have to consider quite carefuly what structure you have. I think that £70 might be a bit optimistic for this!
