Ground Source Heat Lessons for New Build

10/02/2026

What two Amplius schemes show about the practical realities of low carbon heat.

Amplius and its development context 

Amplius has delivered two new build schemes using ground source heat pumps across nearly two hundred homes. The organisation wanted to understand how the technology performs in routine development conditions, not just in small pilots. Formed in 2024 from the merger of Longhurst Housing Group and Grand Union Housing Group, Amplius now manages around forty thousand homes and builds roughly one thousand new homes each year. 

Their approach to technology is pragmatic. Gas remains on some schemes, air source heat pumps on others, and improved fabric standards feature where possible. Ground source was chosen for two developments, one timber frame scheme in Huntingdon and one brick and block scheme in Boston, to test feasibility in contrasting settings.
