There is some help available from external charities/government funds. The DAF grant (discretionary assistance fund) is available from the Welsh Government for people who claim certain benefits. You can apply for this yourself, or a support worker or New Homes Coordinator can apply on your behalf. There are charities available that offer good quality second hand items at very reasonable prices.
