The history of the chimney sweep

---

Early Days (16th–17th Century)
Chimneys became common in England during the Tudor period, as open hearths were replaced with enclosed fireplaces.
Chimneys needed cleaning to prevent soot build-up, which could cause dangerous chimney fires.
Early chimney sweeping was done by master sweeps themselves, using primitive tools like rods, scrapers, and brushes made from twigs.

The Rise of the “Climbing Boys” (17th–19th Century)
By the late 1600s, narrow, twisting flues in London townhouses were difficult for adults to clean.
Master sweeps began employing young boys (sometimes as young as 6) to climb inside the chimneys and scrape soot with hand tools.
These children were often orphans, parish apprentices, or sold by poor families into the trade.
The job was dangerous: boys suffered from burns, suffocation, falls, and a disease later called “chimney sweep’s carcinoma” (a cancer caused by soot exposure).
Many boys lived in poor conditions, sleeping under soot sacks and working long hours.

Campaigns for Reform (18th–19th Century)

Social reformers like Jonas Hanway and Lord Shaftesbury fought against the use of child sweeps.
Between 1788 and 1875, a series of laws attempted to regulate or abolish the practice.
The most important was the Chimney Sweepers Act of 1875, which made it illegal to employ anyone under 21 to climb chimneys.
This finally ended the era of the climbing boy.

Industrial Change (19th–20th Century)
New technology replaced child labour:
Joseph Glass, an engineer from Bristol, is credited with inventing the modern chimney brush (long rods with bristles).
This allowed sweeps to clean flues from the fireplace opening, rather than sending a child up.
As houses modernised and coal use expanded, chimney sweeping became an established trade.

Folklore and Traditions

Chimney sweeps became symbols of good luck in the UK.
It was believed to be lucky to shake hands with or see a chimney sweep on your wedding day.
The tradition is still carried on today, with sweeps hired to attend weddings in ceremonial dress.
This superstition likely comes from the sweep’s role in keeping homes safe from fires.

Modern Era (20th–21st Century)
With the decline of coal fires after World War II, demand for sweeping dropped.

However, the rise of wood-burning stoves, open fires, and solid fuel heating has revived the profession.
Today, chimney sweeps in the UK are trained professionals, often accredited by organisations like the Guild of Master Chimney Sweeps.

Modern sweeps use rotary power sweeping systems, CCTV inspections, and industrial vacuums—far removed from the soot-covered climbing boys of the past.
