Mine's not listed here:

The open data policy does not apply.

The open data policy does not apply to your plan. You can use your monthly data to roam in our EU inclusive countries just like you do at home. For more information on where you can roam, take a look at our inclusive EU roaming webpage.

It states the above for all plan costs, so you’re good!

Be warned though:- 

if you roam more than you use your phone at home (we mean in the UK) over a 4-month period, we might think you’re permanently roaming. If so, we'll take the following action:

First of all, we'll send you a text reminding you of the fair usage policy. If you don't change your usage behaviour to comply with it, we'll also ask you to provide some sort of proof that you have strong ties to the UK, like a UK bill or bank statement.

If you don’t provide any proof of having strong ties to the UK, and you continue to roam in the EU more than you use your plan in the UK, we'll apply a surcharge to your EU roaming usage. When we do this we'll send you another text message - to make you're aware of the situation, and give you a second chance to stop roaming and avoid charges.

The surcharges that will be applied to your account if you exceed our fair usage limits are:

• 3.2p per minute
• 1p per text
• 0.59p per MB

Basically... As long as you don’t take the p*ss, you will be ok. 👍
