Jeld Wen Inc. bought Boulton & Paul (along with another joinery company John Carr) from the Rugby Group plc in 1999 to form its British subsidiary.

In the 1880s Boulton & Paul were leading manufacturers of kits for corrugated iron buildings, which arrived in packing crates ready to be erected.

Its 1920 catalogue contained a choice of twenty-two designs with several varieties of bungalow illustrated, ranging from the 'Modern Residential', through the 'Week-End' and the 'Seaside' to the plain and ordinary (with verandah).

[5] Many of its buildings are still in use, and include Castle Bungalow at Peppercombe, Devon (a former boathouse which is now a holiday cottage owned by the Landmark Trust)[6] and Monkton Combe School's thatched sports pavilion on Longmead, often referred to as one of the most beautiful cricket pitches in England, which is visible from the A36 in Somerset.

A new production site was built and an assembly and proving ground developed on Mousehold Heath in Norwich rather than transport the aircraft to the Army at Thetford.

After World War I, Boulton & Paul made its mark with the introduction of powered and enclosed defensive machine-gun turrets for bombers.

The subsequent Overstrand bomber featured the world's first enclosed, power-operated turret, mounting a single Lewis gun and propelled by compressed air.

This moved to Wolverhampton in 1936 as the area had a surplus of skilled labour and the council was able to provide an incentive in the form of a greenfield site and flying rights.
