There seems to be a lot of rubbish getting posted here (at least in the earlier responses).
As EU citizens, Sherrardk, your family have the legal right to enter any EU country as long as you can prove that citizenship. A British passport provides such proof up until the very last second of the validity stated on it. You can ALWAYS use a valid British passport (irrespective of the time left on it) to enter any EU country.
Only a few non-EU destinations (among the countries popular with British tourists) specify a minimum period of passport validity. (Even the USA, which has some of the strictest immigration rules in the world, waives their normal '6 month validity' rule for holders of British passports).
Some travel agents can't be bothered to train their staff properly. They simply 'cover themselves' by getting their staff to say that travellers will always need 6 months left on their passports, despite the fact that it's hardly ever true.
You can check on the entry requirements, for British passport holders, for any country in the world on the website of the Foreign & Commonwealth Office:

However, as I've already stated (and, thankfully, some of the better-informed contributors to this thread have already done so as well) it's pointless checking on the rules for any EU country because an 'in date' passport is ALWAYS valid for entry into the country.
