Biomass Heritage Project with Harrow Council

The 14th century Headstone Manor in Harrow is one of the oldest buildings in Greater London. It has been brought back to life following a major four-year restoration project made possible by £5.7 million in funding from Harrow Council and the Heritage Lottery Fund.

The funding was used to create a museum and visitor centre, which provide the focal point of the site, showcasing a wealth of fascinating artefacts charting local history and personal stories throughout the ages. Housed in a Grade I listed building, the museum also features video and audio displays which combine to give an insight into Harrow’s rich heritage.

The project also included the restoration of the Great Tithe Barn, which dates back to 1506 and is being given a renaissance as a wedding venue.


Acting on behalf of Harrow Council, Padd Energy designed a 200kW eco cabin with wood pellet burning biomass boiler to provide heat throughout Headstone Manor and Museum.

The biomass boiler also powers underfloor heating in the Great Tithe Barn. This is highly efficient because it only heats the first few metres of the room and not the roof space.

Our Expertise

Solar panels or ground source heat pumps are unsuitable for old buildings such as those at Headstone Manor and Museum, so biomass is the ideal renewable energy option.

Our experience in designing and installing biomass boilers at a range of sites across the UK means we were able to find the ideal solution to the heating requirements for the site, using a highly efficient renewable energy source.

Chris Paddey, Managing Director of Padd, said: “We were delighted to work with Harrow Council on this project to plan and project manage the installation of an efficient renewable energy solution for a heritage building.”
