Until recent proposals, no intervention has been available or mandatory for such short sentences, POGS. There have been voluntary, preventative initiatives by probation services, but they were stopped by successive government because they weren't legal requirements. Sex offenders and certain very high risk offenders who need multi-agency management in the community are the exception.
The government is privatising and breaking up sections of offender management that has been covered by probation, and bringing in supervision of short sentences. It's not gone though its final stages yet. It's all a bit of a dog's dinner, and it will cost the tax payer a fortune to bring in private supervision of those revolving door petty and lower risk offenders who keep going in and out of prison. When it's finalised, supervision of short prison sentence offenders doing work in their community may happen - a bureaucratic nightmare, as breaching such conditions means taking someone who didn't do his fortnight or month's work filling in potholes or picking litter back to a clogged up court. Doesn't sound too hopeful, does it?
