The best Christmas opportunities are in retail and hospitality. Many shops take on extra staff at this time, in fact if you look at your local newspaper or magazine (print or online) you will probably find several vacancies being advertised.The same is true of pubs and restaurants (you may have to be over 18 for some of these).
The post office also employs a lot of temporary staff before Christmas. You can go direct to your local post or sorting office and ask, or check for jobs on the uk post office website.
This is also a busy time for informal networks such as gumtree. If you put 'gumtree norwich' (or whatever the name of your nearest big town is) in a search engine, you will be taken to a page of relevant information for your area, and on that page you will see a link to local jobs.
The next step is to visit your local job centre. Again, you can find the address if you put 'job centre' and your local town's name in a search engine. Good luck.
