Yes and no.
The Feed in Tariff (FiT) scheme that was introduced in April 2010 ended in March 2019.
However, as the cost of technologies has fallen dramatically and the cost of grid supplied electricity has increased, (particularly the non-commodity element) since the FiT was introduced the business case for onsite renewable energy generation will often make complete sense. The trick is to size the system correctly.
The FiT certainly did its job with over 800,000 domestic installations deployed. Subsidies should not be permanent, they were probably set too high in the first place so an investment in renewables, particularly solar was based on maximising the subsidy revenue without enough emphasis on whether the technology delivered generation to meet the demand profile on the site.
