Gas Connection Design and Consulting
Some connections are decided long before anyone breaks ground. We provide connection design for complex loads and constrained sites, prepare adoption submissions, and coordinate the gas route alongside the other utilities so trenching and phasing work as one plan rather than four.
What the work involves
- Load assessment and diversity calculations for the proposed scheme
- Point-of-connection enquiries and capacity confirmation with the network
- Route design, easement considerations and meter position planning
- Adoption submissions and the associated technical documentation
- Multi-utility coordination so gas, water, electricity and telecoms share the trench plan
- Buildability and phasing advice aligned to your construction programme

Frequently asked questions
When should connection design start on a development?
As early as possible. Point-of-connection and capacity answers can take time, and the outcome often affects plot layout, meter positions and trench routes — all of which are cheaper to change on paper.
Can you coordinate gas with the other utilities?
Yes. We design the gas route to sit alongside the other services so the trenching plan and phasing work together rather than clashing on site.
What do you need from me to price a design?
A site plan or layout, the intended use and unit numbers, and any load information you already have. If some of that is still unresolved, tell us and we will price the design around what is known.
