Would they reassess my PIP before I retire?

I've just been reassessed for PIP and been awarded "for an ongoing period". In the explanation they mentioned that "When we made our previous decision we gave you PIP for a set time because we expected your needs to change. The information provided shows your needs have not changed and are continuing based on the medical evidence received. I decided to award you PIP for a longer time. Your rate of PIP has not changed.

I have been on DLA and PIP for mobility and daily living needs (enhanced rate for past 11 years).

I will be 66 next year and not sure if it means they would re assess me before I get retired or I will continue to get the award at the same level after retirement.

Thanks
