Background

The restoration work has preserved the Grade II listed chapel’s unique features, some of which date back to when St Thomas’ Hospital opened on its current site opposite the Houses of Parliament in 1870.

Reverend Mia Hilborn, Head of Spiritual Healthcare at Guy’s and St Thomas’ NHS Foundation Trust, says: “Patients, staff and visitors have used this chapel as a place for quiet reflection and prayer for nearly 150 years. It’s a privilege for us to be able to share these moments with them in such a beautiful and historic space.”

The restoration work was funded by a grant from Guy’s and St Thomas’ Charity and donations from The Perseverance Trust, the Friends of St Thomas’ Hospital and more than 500 individual donors who were thanked at the service.

Ventilation

Carry out the works to the ventilation wind catcher on the roof, clean it and provide future access to the internal grille for maintenance. Access to the roof will be required and will be supplied by the main contractor

Heating
