Navigating District Heating Compliance: From CP1 to CDM

Compliance isn’t just a tick-box exercise — it’s fundamental to the success of every district heating scheme. At Design Tech Solutions, we guide clients through the ever-evolving regulatory landscape, ensuring their heat networks meet both national standards and local planning requirements. Whether you're a local authority, housing developer or design lead, we help you stay on track with key guidance such as CP1 2020, HNTAS, CDM regulations and energy zoning frameworks.

Why Compliance Matters in District Heating

book-cover-of-code-of-pracitce-for-heat-networks

District heating systems must meet high standards for safety, efficiency, and environmental performance. From pipework specification to health and safety documentation, getting it wrong can lead to costly redesigns, planning objections, or even project failure.

Regulations around heat networks are evolving fast in the UK — with increased emphasis on consumer protection, energy efficiency, and carbon reduction. Navigating this complexity requires technical understanding and experience across multiple regulatory domains.

How We Help Clients Meet District Heating Regulations

At DTS, we provide compliance-led design and advisory services that support clients at every stage of project development.

  • CP1: Code of Practice for Heat Networks
    We align designs with CP1 2020 principles — covering everything from pipe sizing and insulation to metering and temperature control.

  • HNTAS Readiness
    We help clients prepare for the Heat Network Technical Assurance Scheme, building compliant documentation and evidence for performance assurance.

  • CDM 2015 Compliance
    We ensure your heat network project meets Construction (Design and Management) Regulations — from risk registers to Principal Designer duties.

  • Planning Support & Local Authority Standards
    We support planning submissions with compliant design statements, environmental assessments, and consultation-ready outputs.

  • Regulatory Checkpoints Throughout Design
    We build compliance into each stage of the design process — helping avoid rework or delays during approval or tendering.

FAQ

What is CP1 and why does it matter? +
CP1 is the UK’s Code of Practice for Heat Networks. It outlines best practice for design, construction, and operation of heat networks to ensure safety, efficiency and performance.
What is HNTAS and is it mandatory? +
HNTAS is a new assurance framework designed to ensure quality and performance in UK heat networks. It’s not yet mandatory, but is likely to become a requirement for public funding and consumer protection.
What’s the role of CDM in heat network projects? +
CDM 2015 regulations apply to all construction projects in the UK. In district heating, this means clear allocation of design responsibilities, risk assessments, and health & safety controls during delivery.
Can DTS help with planning applications? +
Yes. We assist with compliant design documentation, statements for planning, and technical responses for local authority engagement.

Common UK Standards We Work With

RIBA-booklrt-for-Plan-of-Work-district-heating-design

We help clients meet technical and regulatory standards that shape the design and delivery of heat networks in the UK, including:

  • CIBSE CP1 – Code of Practice for Heat Networks

  • Heat Network Technical Assurance Scheme (HNTAS) – Design and performance verification

  • RIBA Plan of Work – Aligned deliverables across every stage

  • Local Authority Design Guides – Ensuring integration with planning and environmental requirements

Our designs are created to meet — and exceed — these frameworks.

Stay Compliant. Stay Ahead.

If you're designing or delivering a district heating scheme, staying ahead of regulation is key to getting it right — on paper, on site, and in operation. We’re here to guide you every step of the way.
