Why were privately operated English and Welsh lighthouses transferred to Trinity House in 1836?

In England and Wales, privately operated lighthouses were transferred to the Corporation of Trinity House in 1836 due to growing dissatisfaction with the service provided by private owners and the high level of charges they imposed.1

Historically, many lighthouses were operated by private individuals who held concessions granted by the crown, which authorized them to collect light dues from mariners. Because these private operations often resulted in poor service and excessive costs, Parliament passed an act in 1836 to purchase these lights and consolidate their administration under Trinity House, an autonomous agency responsible for the provision of seamarks.1
