No. Kits that include a USB power adapter ship with a standard EU plug, and we do not put UK, AU or other regional adapters in the box.
It is a fair thing to check before ordering, but it rarely leaves you stuck. Our devices that take mains power charge or run over micro USB or USB-C, so any USB power adapter you already own will do the job, including a phone charger.
Some of our kits run on AA or AAA cells instead, so for those the plug type does not come into it at all.
The same goes for the soldering iron, if your kit includes one — it takes its power over USB, so your local plug type makes no difference there either.
