Chimney sweep market trends

(last updated July 2019)

What has been happening in the chimney services sector

Until the 1960s coal was the main fuel for domestic heating and this generated strong demand for the chimney sweep's services. However, the 1960s and 1970s saw gas beginning to replace coal and this led to many traditional sweeps leaving the trade or retiring. Those that remained had to become familiar with cleaning gas chimneys where previously they had only cleaned coal, wood and oil chimneys.

The switch away from coal has continued and now many homes are heated by gas, oil or electricity. Many don't have an open fire at all. If there is an open fire it may only be lit every now and then, meaning that some customers don't get their chimney swept every year but every four or five years. Some chimney sweeping businesses now have thousands of customers where previously they had hundreds - the difference being that many of these customers have their chimney swept every three or four years instead of annually.

Modern chimney sweeps now offer a wide range of chimney services. They may be qualified to work on gas, oil and solid fuel appliances as well as being able to clean flues serving all fuels (coal, wood, peat, oil and gas). The National Association of Chimney Sweeps (NACS) has been active in highlighting the danger of carbon monoxide poisoning from blocked flues and the need to have gas chimneys cleaned regularly. Also, regulations have been brought in which require landlords to make sure that appliances and flues and chimneys are checked for safety once a year - they can't pass this responsibility on to their tenants. This has helped to maintain demand for chimney sweeps' services - or 'chimney technicians' as some now call themselves.

Recent years have seen wood burning and solid fuel stoves become popular, partly as they are fashionable and partly because of rising energy prices. This has also boosted demand for the chimney sweep's services, especially as chimneys for these burners need sweeping as often as every quarter when they're in use.
