The group, which is owned by Heineken, said some 80 pubs will be “completely transformed” with makeovers costing between £125,000 and £400,000 each.
Every scheme will be “bespoke” and tailored to the pub and the community it serves.
Star Pubs and Bars said as Britons travel less and many still work from home, the investment will focus on creating “premium locals in suburban and high street locations within a 10-minute walk from residential areas”.
The revamps will also aim to make the pubs “more comfortable and stylish” inside and improve beer gardens.
Lawson Mountstevens, managing director, Star Pubs and Bars, said: “Many people have rediscovered the joy of their neighbourhood pub between lockdowns over the last year, and are opting to stay local. This investment responds to that demand giving communities quality pubs on their doorsteps.
“We’ve spent £62m on rent cuts to keep our pubs afloat during the pandemic. The pandemic has shown the resilience of the great British pub and especially the leased and tenanted model. We’re committed to building on that support with refurbishments, so that pubs around the country thrive for the long term.”
