In a remarkable fusion of sustainability and historic preservation, Warksburn Old Church in Northumberland has become what is believed to be the world’s first church to be transformed into an EnerPHit-certified home.
The former Presbyterian church, originally built in 1875, underwent a £1million renovation between 2023 and 2024, transforming it into a holiday retreat while preserving its architectural heritage.
Join us as we explore this extraordinary conversion and the visionary efforts of owners Anne and Alan James, whose dedication has not only honoured the church’s past but also set a new benchmark for Passivhaus living.
Church conversion outperforms EnerPHit standard
The church has undergone an EnerPHit retrofit — EnerPHit being a specialised approach designed for upgrading existing buildings to meet high-energy performance standards.
EnerPHit is the Passivhaus standard for existing buildings, focusing on achieving exceptional energy efficiency and comfort while preserving a building's character.
This project not only achieves a EnerPHit certification but also a net-zero performance through on-site renewable energy generation and an extensive retrofit strategy.
This rejuvenation of the church, which dates back 149 years, is a nod to its innovative origins. Its construction was funded Sir George Barclay Bruce, the pioneering engineer, who was said to first imagined renewable electricity.

The project recently reached a significant milestone with an airtightness test result of 0.19 ACH (air changes per hour), far surpassing the EnerPHit standard requirement of 1 ACH and even exceeding the stringent Passivhaus classic target of 0.6 ACH.
This remarkable level of airtightness, combined with a mechanical ventilation with heat recovery (MVHR) system, high-performance insulation in the floor, walls, and roof, and highly efficient windows and doors, makes Warksburn Old Church one of the UK’s most energy-efficient historic domestic buildings.
