pension reduction
I also just received my letter from xafinity. My reduction amounts to £244.29p an 8.15% reduction.
It appears that all Public sector pensions are subject to this rule; however most are restricted to a much lower reduction, a teachers pension, for instance, is restricted to £1.70 per annum for each year of service, to a maximum of £54 per annum, other public service pensions are to a maximum of £67.75 (pension manual).
I shall certainly be speaking to my MP about this.
