If its a Performance power rake from B&Q check with them if they can order one. If it's not that old and they can't ask why the sell Performance Power tools with inadequate accessorie availability which seems to be the norm with many products made in the third world so end up false economy.
I know I fell in to that 'cheap' trap not anymore save for known British or German tools.
