What was Penge Boots is now run by a small chain that has pharmacies across London. Peckham Boots is still open.
Lloyds Pharmacy have also been moving out of the retail business. They plan to close their East Dulwich store in the near future. They've closed a store they had in Bellingham and the Peckham store is now independent.
To be honest, I last used Boots Forest Hill for either click or collect or prescriptions before Covid. Since then, my electronic prescriptions are sent to Sadlers opposite Dulwich Library.
