In a large bowl, mix warm water, yeast, and 5 tablespoons honey. Add bread flour, and stir to combine. Let sit for 30 minutes, or until bubbly.
Mix in 50g melted butter, remaining honey and salt. Stir in 1/2 of the wholemeal flour.
Dust a flat surface with flour and knead with wholemeal flour until slightly sticky - just pulling away from the counter, but still sticky to touch. This may take additional wholemeal flour. Place in a greased bowl, turning once to coat the surface of the dough. Cover with a tea towel. Let rise in a warm place until doubled.
Punch down, and divide into 3 loaves. Place in greased 23x12cm (9 x 5 in) loaf tins, and allow to rise until dough has topped the tins by one inch.
Bake at 180 C / Gas mark 4 for 25 to 30 minutes. Lightly brush the tops of loaves with remaining melted butter when done to prevent crust from getting hard. Cool completely on wire racks.
