Hi Rox
As stated in your previous question you need to report any saving over £6k as this will affect you UC entitlement.
Between £6k and £16k for every £250 bundle or part of, you will loose £1.00 in tariff income. Once you go over £16k you will loose all entitlements to any means tested benefits.
