'Can I buy Bonds if I live outside the UK?
In some countries. First you should check whether local regulations allow you to buy and
hold Premium Bonds, as some countries don’t allow this. You can only apply in the first instance
by post as you’ll need to send us some documents to prove your identity and address. We’ll
also need your Tax Identification Number and date and place of birth if you live in the European
Union.
For full details before you apply, visit our website. nsandi.com Or call us on SPAMMER 1253 832007.
Calls will be charged at the rate of your international phone provider.
Once you’ve done all this successfully, then probably the easiest way for you to buy more Bonds is to register for our online and phone service.

So it doesn't seem to be a UK issue. And the question might then be, do SG ban UK citizens buying them? Not that I'm aware of, and why would they anyway? In many ways it's simply like buying UK government gilts/treasuries.
p.s. The pay-out total is 1.35%, though that is tax-free. I'd suggest they're ok for a bit of fun but not as a serious investment. About 20yrs ago I held the max allowed, £20k, and in the c3yrs I held them I think I got one prize of £10. I.e. in inflation-adjusted terms my money was going backwards, pretty fast. To me it's like a parallel to the National Lottery.
