DH and I have one each, we get the equivalent in child tax credits towards our childcare costs as to what we would get if we used the tax free child care scheme, so it made sense to stay on tax credits so we could open the help to save accounts.
For those moaning that people on benefits shouldn’t have money spare to save, we don’t go on holiday, don’t drink or smoke and budget so we can afford to save a bit towards unexpected costs.
