Contractor Walter Lilly has just completed a £40m refurbishment and refit of Lambeth Palace in central London, complete with double glazing and heat pumps.

Home to Archbishops of Canterbury for 800 years, the Grade I listed buildings of Lambeth Palace date back to the 12th century.

Installation of a new energy centre will enable a move away from reliance on fossil fuels, with the palace ultimately being served entirely by on-site renewables, with rooftop solar panels. Three air source heat pumps have been installed, 160 windows double glazed and 140 radiators replaced.

The refurbishment work included the restoration of the 17th century Great Hall, where the timber roof structure, damaged during the Second World War, has been repaired. In consultation with Historic England, the project involved timber specialists, stonemasons and conservationists, who replaced 1450 sqm of floorboards, repaired and cleaned 800 sqm of stonework and completed 13,500 sqm of plastering and painting.

Over the course of the project, 39 tonnes of timber was recycled.

Walter Lilly managing director Chris Butler said: “The successful completion of the reservicing works at Lambeth Palace represents a major milestone in the conservation and modernisation of one of the UK’s most treasured historic buildings. Despite the complexities of working within a live, occupied environment and navigating archaeological discoveries during underground installations, we are immensely proud to have played a role in delivering a sustainable solution that supports the Church of England’s net-zero ambitions. This project demonstrates how heritage sites can be sensitively and sustainably adapted to meet the needs of the future.”

The £40m project was funded entirely by the Church Commissioners.
