Heat the oven to 200C and oil or line a baking tray.
Place the chicken breasts on the tray and wrap two slices of bacon around each. Cook in the oven for 25 minutes. (You may want to flip the chicken over as it cooks so the bacon underneath can crisp.)
While the chicken is cooking, mix the ingredients for the sauce and cook in a pan on the hob over a medium heat for about 5-10 minutes until thickened.
After 25 minutes pour the barbecue sauce over the chicken, add the grated cheese and return to the oven for a further 5 minutes.
