Preheat the oven to 200C/180 fan/gas mark 6. Put the potatoes in a saucepan and pour over enough water to cover them. Bring to the boil and then simmer until tender. When cooked, drain thoroughly and mash with a splash of milk and some butter. Season with ground black pepper.
Meanwhile, put the butter& flour in another pan and heat gently until the butter has melted, stirring regularly. Gradually whisk in the milk and bring to the boil, stirring to avoid any lumps. Add the chopped parsley & stir, cook for 3-4 minutes until thickened.
Take off the heat and stir in the fish, sweet corn and peas. Spoon into an ovenproof dish.
Put the mashed potato into a piping bag with a large rosette nozzle and pipe large swirls on top of the fish mixture and sprinkle with cheddar cheese. Put in the oven for 20-25 minutes or until golden and bubbling at the edges.
