Grid connection consultants for housing and mixed-use developments
Residential and mixed-use developments need new distribution networks, often built by an ICP and adopted by the DNO or an IDNO. Heat pumps and EV charging are increasing the electrical load per home.
- Typical size
- 0.5 MW to 20 MW
- Typical voltage
- Low voltage to 11 kV; 33 kV for large schemes
- Route
- DNO or IDNO network, often built by an ICP
- Timeline
- Linked to phasing and local substation capacity
Connecting housing and mixed-use in the UK
Consultancies in this category handle load estimates, applications, ICP and IDNO options and coordination with phased build programmes.
Current regulatory issues
- All-electric homes increase the after-diversity maximum demand used to size networks.
- IDNO adoption can affect asset value payments and long-term ownership.

Housing and mixed-use: common questions
Q01Should a housing development use an IDNO?
It can. IDNOs adopt new networks and may pay an asset value for them. The DNO still provides the upstream connection. Compare offers on cost, terms and programme.
Q02Who builds the electricity network on a new development?
Either the DNO or an accredited ICP. Using an ICP gives you more control over the programme for the contestable works.
Q03How do heat pumps affect a housing connection?
They raise the electrical load per home, which can increase the capacity needed and the cost of the connection.
