The only home maintenance is to clean the filters. Regassing may be needed, but is not really a diy job in the uk. In America small top up cans of r22 are sold, but not here AFAIK.
I am afraid you need to call an aircon service place, best bet is to collar someone in an aircon van and offer cash for them to check the pressures and regas as needed.
