As far as I can see, you were born around 1951 and looking at the pensions website your entitlement for both state pension and pension credit kicks in in 2016. Are you sure that you are not talking at cross purposes with the DWP and they are telling you when you will start to be credited with pension contributions? You do confuse things a bit by talking about your wife's potential retirement date, which might be 2014, but her right to a pension will not affect yours in any way, unless you have no entitlement and she has enough contributions to claim the full married persons allowance.The picture you paint is incomplete as you do not say what NI contributions you may have paid during your years of self employment and therefore what your entitlement due to those contributions might be, also whether you have contributed to any private pensions. The right to a state pension can be horrendously complicated in unusual cases and is affected by all sorts of issues that you must be careful to declare to the DWP. I found that any assumptions they make are very "broad brush" and that they don't necessarily ask all the questions you may expect, so if you do not volunteer the full picture, you get an incorrect assessment. peterpensioner gave the best advice, gather all the relevant facts about income and problems together and make an appointment with the CAB, they have a good track record with things like this.

Plonk, I typed this out before I saw your latest post, and unfortunately did not come up with the same result as you. That doesn't mean I am right, as I said, I do not possess all the information. However, having re-read my post, I still think that the basic message stands that you will need and expert and have to be very careful with the information you provide and the terminology in use. From your figures, the earliest retirement date for a man born in 1952 is 65 (2017), but there may be individual circumstances that bring other factors in to play, so tae peterpensioners advice, please!
