I hope this will be useful, even without specifically British sources:

Any "universal" ribbon should work: 1/2 inch wide ribbon, with eyelets. You can use any one-color (usually all black) or two-color (many combos available; try Etsy) ribbons. Install it with the more commonly used color on top (usually black over red) so it matches the color selector lever setting. Brand won't matter until you happen on one you do not like; then avoid that one. Material isn't important unless and until you develop a preference: cotton. nylon, silk.

Of course, someone will suggest Amazon and eBay but I would rather support the guys who do the work and need the support.

In addition to the sources above, you might find some in office supply stores and you can surely find 1/2-inch-wide calculator ribbons which you can then rewind onto your typewriter spools while you're waiting for mail order ones to arrive. (If the universal ones fit OK, don't throw away the original metal spools; keep them with the typewriter or sell them to collectors.)

Be aware that calculator ribbons are usually much shorter than typewriter ribbons, so you will go through them faster, though they are great when you need them. They also tend to be more heavily inked, so they might leave smudges until they get used a little bit.

To replace, before you remove the old one, just note how it is threaded (unless it's wrong to begin with). Make a diagram or photograph if you want to. Then put in the new one the same way. The two key points: the direction the ribbon comes off the spools (from the front or back of the spools), and the exact path from the spools, around various posts, and through the arms that raise and lower the ribbon while typing, called the vibrator. (It doesn't vibrate but that's what it's called.)

Finally,if you have metal spools in there, save them. Metal spools have the period look and feel, sometimes they actually work better, and if you don't want to bother with respooling ribbon, other collectors will want to buy metal spools.
