Hi Wolf
You are not asking the wrong question. It would depend on which threshold you are talking about; £10k or £16k.
From a DWP perspective, they would want to see bank statements from when her savings went over £10k, once savings go over £10k for pensioners, they will be subject to tariff income.
Tariff income for every bundle or part bundle over £500 the claimant would loose £1.00 in benefit. Once her savings go over £16k then she would loose PC entitlement.
