192.com allows to search the electoral roll by address or by postcode. However, it's a subscription service and it doesn't come cheap. (You have to buy credit packages, starting at �34.95 + VAT = �41.07, to use the system).
Even so, 192.com can only search the 'edited' electoral roll (which can be sold by local authorities to junk mailing services and firms like 192.com). Most people now mark the box, on their electoral registration form, which excludes their details from the edited roll, so you'll only find some of the people living on that street, not all of them.
Your local reference library might have the UK-InfoDisk available for you to consult for free. That CD-Rom contains the same information as 192.com does online, but there are different versions of the disk and you might find that your library has purchased one of the cheaper versions, which don't offer the full range of search facilities. However, since it's cheaper than forking out 40 quid, it might be worth a try. (However, you'll still only get the information from the edited electoral roll).
It's a serious criminal offence for anyone to make the 'full' electoral roll details available electronically (either online or on CD) to unauthorised persons. (The intelligence services, the police and credit reference agencies are among the few bodies allowed to access the data). However, the law requires all district councils (or unitary/metropolitan councils, where appropriate) to make the paper version of the local electoral roll available for anyone to consult at council offices. Voters are listed by street and house number (rather than alphabetically by name) so, if you live near to the area you're interested in, it would be ideal for your purposes.
