You can access all of Telegraph Newspapers puzzles (including the Sunday ones) for £2.99 a month. You can also access a single puzzle each day free of charge (although I've experienced problems with the site when trying to do that on occasions). So that might be one possibility for you:

I only buy the Saturday edition of The Times so, regrettably, I can't help you. However (wearing my moderator's hat here) I'll ask that if you do post an email address on this site, you use one specially created for the purpose (rather than your regular email address). If you need a site to create a new email account, I recommend this one:
https://www.gmx.co.uk . (When posting your new email address, it would probably be best to mention that it's a 'throwaway' one, so that an over-zealous moderator doesn't remove your post!)
