Quality District Heating Company & Water Infrastructure Experts
WE HAVE A DEDICATED WORKFORCE
CONTROL = QUALITY
Proven Project Construction (PPC) is a leading district heating company and water infrastructure specialist, delivering projects across London, the UK, and Ireland. Founded in 2017, we brought together a leadership team with over 80 years of combined district heating, pipeline, and water infrastructure expertise under one roof. As one of the most established district heating companies in the UK, we specialise in designing, supplying, and installing district heating services, encompassing civil and mechanical works, to provide comprehensive solutions for large-scale buildings and facilities. Our methodology as a company is efficient and transparent, so clients have a direct line to senior project managers. And because we are passionate about sustainable practices and greener futures, we’re going all out to lead the industry towards a carbon net-zero future.
We are writing the future of London district heating and infrastructure across the UK and Ireland. In 2019, we expanded into Ireland, becoming one of the few Kingspan LOGSTOR-accredited district heating companies in the country. As a main contractor or trusted subcontractor to energy companies, councils, developers, and mechanical contractors, we’ve become one of the leading district heating providers in the UK, behind high-profile projects including Queen Elizabeth Olympic Park, Clapham Park Regeneration Scheme, and Dublin Airport Terminal 1. Today, we’re expanding into water infrastructure, backed by a directly employed workforce, ISO-certified management systems, and digital project delivery through Procore.

INDUSTRY EXPERTS – OUR TEAM
As one of the best district heating providers in the UK and Ireland, Proven Project Construction is headed up by three directors, industry experts with over 80 years of combined expertise at the highest level of district heating and large pipeline infrastructure projects: Denis O’Connell, Michael Heffernan, and Mish Hoque. We believe that where our competitors stand still in evolving and adapting, we have the knowledge and foresight to see things differently and never stop moving.
To enable us to continue to work towards best-in-class solutions, we invest time and money into our workforce to make them the best team in the industry. Not only do we employ a direct labour force for better control and quality, but our professionals are multi-skilled to meet any challenge hands-on, head-on. So whether we are excavating trenches, installing temporary works, welding, testing, or jointing, our transferable expertise is working harder than any other contractors to keep a tighter rein on the budget and deliver on time.
And in our small and highly specialised industry, as one of the most established district heating companies in the UK, we continue to foster a reputation for the human touch, for collaboration, and for successfully building and maintaining district heating systems anywhere in the UK.
