Have not heard of Screwfix before. Took the bus out to B&Q and got two bulbs at 4 quid each, so we now have a spare. There are very few incandescent bulbs left in the house now, but there are those nasty recessed lights in the kitchen and bathrooms that have what seem to be little halogen bulbs in them. I'll need to replace those - every time I turn on the overhead lights in the kitchen my smart meter acts as if I've fired up the oven!
