warmfront. My husband and I both lost our jobs this year, so returned back to uni. We have small children and our heating went down not long after the above. Warm front were amazing, we have a brand new boiler, a replaced radiator and the house is warm at last. I cannot recommend them enough. My elderly neighbour is getting hers done in a few weeks after we recommended she did. It does take a while as they send an assessor round and book you in etc, but its worth it.
In the mean time, make sure you stay as warm as you can, you can contact your energy company who can help with discounts for OAPs and hardship . good luck
