I have used a rate of 1.2 to convert Euros to British Pounds. Your non-UK pensions total £88,000 Euros which equates to £73,333. Deduct 10% and you are left with £66,000 subject to UK tax. Add the UK state pension of £2,000 and you have income before the deduction of the personal allowance of £68,000. As your income is well above the point at which you cease to be entitled to age allowance, you will have a personal allowance for 2014/15 of £10,000. Deduct that from your total income of £68,000 and you are left with taxable income of £58,000.
The first £31,865 will be taxed at 20% (£6,373) and the balance of £26,135 will be taxed at 40% (£10,454). Your total UK tax liability will be £16,827.
Your wife's income will be £2,083 per annum. As that is way below the personal allowance she will pay no UK tax.
In summary, your total joint income will be £77,417. Deduct the UK income tax of £16,827 and you are left with a net of UK tax joint income of £60,590.
I don't know what assumptions were made as to the division of income between a married couple for the purposes of the DT calculations and it is always dangerous to assume that such figures are how it should be. Clearly, as your wife has a low income, she is not using most of her personal allowance. From 2015/16, however, it will be possible for her to transfer to you £1,000 of her personal allowance. That is, of course, subject to the potential for a change in government in May 2015.
I'm not an expert on Irish tax but according to the UK/Eire tax treaty, you should only be liable to UK tax on your pensions assuming you are resident in the UK.
I hope this helps but let me know if you have nay further questions.
