im in brum and we had to call out a chimney sweep last week before we could install a new gas fire for a customer, he only charged �40 which is a bargain !
Alternatively, you could buy your own chimney brush and rods for about the same price (rods �25.99, brush �6.19), then next year when you come to do it it'll be free! Screwfix sell them.
Free....... if you send ur 5y nephew up the chimney. Have been here 30y & used fire every winter & never had chimney cleaned.....spose may suffer soon?
Mine throws down bits which burn-up......self-cleanser?
