UK electrical distribution substation at dusk for feasibility studies and DNO budget estimates
DNO Feasibility & Budget Estimates

Know your grid options
before you apply

Rapid desktop capacity checks, connection routes, and indicative costs for LV/HV demand and generation. We also manage DNO Budget Estimate requests end‑to‑end.

3–7 day feasibility · All UK DNOs · LV/11kV/33kV
What this service covers

Feasibility vs Budget Estimate

We provide two complementary routes to de‑risk your project. A fast desktop feasibility to understand likely constraints and options. Then, where helpful, a formal DNO Budget Estimate to secure a non‑binding cost and outline programme for connection works.

Desktop Feasibility Study

  • •Nearby substation/feeders and probable Point of Connection (LV/11kV/33kV)
  • •Indicative headroom and reinforcement risk
  • •Options matrix with pros/cons, cost ranges and timelines
  • •Recommended route: G98/G99/G100, SoW, ICP/IDNO where applicable

DNO Budget Estimate Management

  • •Preparation and submission to the relevant DNO
  • •Clarifications, tracking, and escalation
  • •Plain‑English summary of outcomes and next steps
  • •Typical DNO turnaround: 4–6 weeks (varies by region)
Deliverables

What you get

Clear, actionable outputs to make go/no‑go decisions with confidence.

Network context

Substation proximity, feeder routes, historical constraints and probable PoC voltage.

Capacity & risk

Indicative headroom, reinforcement likelihood, and key technical risks (fault level, P28, G5, ANM).

Costs & timelines

Option costs (range), programme estimates, and dependencies by connection route.

Connection options

LV, 11kV, 33kV options with pros/cons, metering and ICP/IDNO opportunities.

Next steps checklist

Application strategy (G98/G99/SoW), documentation pack, and site readiness items.

Report & summary

PDF report plus a one‑page executive summary for clients and stakeholders.

Simple process

How it works

From scope to actionable answers in days, with DNO engagement when you need it.

Step 1

Scope & data

Share site details, capacity needs, technology mix, and programme.

Step 2

Desktop study

Network context, headroom and option modelling with risk assessment.

Step 3

Report & review

PDF report and a review call to agree next steps and application route.

Step 4 (optional)

Budget Estimate

We submit and manage the DNO Budget Estimate, summarising outcomes.
