I bought this for my parents, from another seller - who neglected to mention that it was the German version.
The physical set-up was simple - plug the base unit into the charger, landline and router, plug the phone stand into its charger, drop the phone into it. Done. The handset had enough juice in it that we were able to test the thing immediately, although we were probably supposed to charge it first.
Actually configuring the thing was a bit of a pain, because (surprise surprise) the UK isn't in the list of countries. If I remember rightly, there was also a problem with inputting a "region code". It does have English in the language options, thankfully.
Outgoing landline and Skype-to-Skype calls, and incoming Skype calls, worked fine straight away. We had some difficulties with SkypeOut, and with incoming landline calls, that you need to know about.
SkypeOut calls failed until we replaced the leading "0" in the phone number with "44" (or maybe +44). You may need to update your SkypeOut contacts accordingly.
Incoming landline calls worked, but the answering machine is a problem. My parents usually use Call Minder (1571), which worked until Dad inadvertently turned the answering machine on. Not a huge problem, except that it answered the phone in German... and we're pretty sure that just cycling the power turns the answering machine on. Some configuration may fix this; maybe just recording a message in English will make it less of a problem. For now, they're being exceedingly careful about keeping it turned off. (I fear that the sleek black unit may eventually suffer the same fate as Dad's "I keep hitting Caps Lock" keyboard and have the button ripped out of it.)
It says "No PC required" on the box... This is true if you're the "don't read the manual" type, because said manual is a CD-ROM. *facepalm* That particular work of genius is probably true of the UK version too. On this version's CD-ROM, though, you can look forward to a bewildering array of languages, none of which is English. Philips' website does have the English version in PDF form, though.
In short: This phone will indeed do the job, and do it well, but you need to be aware of the quirks that the German version will cause you. If you can handle those, I'd say go for it, it's a good piece of kit (although I still prefer my Netgear SPH200D, which sadly isn't made any more).
My parents have chosen to keep it, and seem to be doing OK with it. However, you should be aware that the official advice from Philips' online support person was to send the phone back and get a UK one. Your, um, call.
