Delivering Across Domestic, Social Housing, Commercial and New Build Sectors.
Henman Dunn delivers plumbing, heating, renewable energy and mechanical services across the domestic, social housing, commercial and new build sectors throughout the East Midlands.
From planned maintenance and responsive repairs through to large-scale heating replacement programmes, renewable energy installations and new build developments, we provide clients with a single delivery partner capable of supporting projects throughout their entire lifecycle.
Our experienced team supports homeowners, housing providers, local authorities, developers, principal contractors and commercial organisations, combining technical expertise with practical delivery experience to ensure projects are completed safely, efficiently and to the highest standards.
We understand that successful projects are about more than installation alone. Whether working within occupied homes, live construction sites, commercial premises or community buildings, we focus on communication, coordination and customer experience as much as the technical aspects of the work itself.
By bringing together expertise in plumbing, heating, renewables, servicing, compliance and refurbishment, we help clients simplify delivery, reduce risk and achieve consistent outcomes across every project.

Our headquarters site was originally home to the Old Glasshouse Inn — one of Codnor’s oldest public houses.
Ashley Henman and Kieren Dunn launched the business with a focus on quality plumbing and heating across East Midlands.
ASHPs, Solar PV and Battery Storage became a major offering as the industry shifted to low-carbon heating.
From Glasshouse Hill we support domestic, social, commercial and new-build clients across all our services.
The original inn was rebuilt under Mansfield Brewery ownership, keeping the site as a local landmark.
We began supporting housing providers with servicing, heating replacements and responsive repairs at scale.
With 35 employees delivering over 7,000 service visits annually across the East Midlands.
Our office is based in Ripley, giving us fast access across Derbyshire and the wider East Midlands area for everything from emergency callouts to planned installation work.
