How do I add my Spanish National Insurance Contributions to my UK pension?

I currently have 4 years of contributions on my UK National Insurance record, but I worked and contributed in Spain for over 20 years, 1988-2010. Can I use those contributions to top up my UK pension? (due 7 June 2032)

Hi Simon,
Please call The Pension Service Future Pension Centre on 0800 731 0175 and they will be able to discuss your current and future entitlement to a UK State Pension and whether any contributions paid in a EU country could be included.
You may wish to receive a State Pension Forecast which you can obtain via: Check your State Pension forecast.
Thank you.
