The details you've given don't entirely fit, so I doubt I'm right, but due to the sisters & late night channel 4 airing, could it be This Filthy Earth?
I am looking for a film which was shown on Channel 4 around 28th / 29th March quite late at night.
I only caught some of it but it seemed really good:
A father and two daughters were living in a pretty dillapidated house in the country, the mother had left them. The older daughter kept wearing her mothers clothes. Near the end the father builds a bonfire and burns all the mothers clothes. Pretty bleak film!
Any ideas much appreciated!

Think this may be Clio Barnard's short film Flood (2004).
