Before you apply: pre-application support
Align load, generation, and export assumptions with what the network can support—reducing rework on your DNO grid connection request.

DNO grid connection request — support from application to energisation
Submitting a DNO grid connection request is how you connect solar, BESS, EV charging, new load, or export to the UK distribution network. ArcGrid EMS helps you prepare the application, interpret the DNO connection offer, integrate assets—and run energy management software that stays within approved import and export limits after go-live.
How we support your DNO grid connection
Practical help across the same stages DNOs and Ofgem describe—from pre-application through to operations.
Application-ready technical packs
Site plans, asset schedules, and export forecasts structured the way connection teams expect—whether the project is solar, BESS, CHP, or mixed.
Connection offer → EMS rules
Translate DNO connection offers into metering points, export caps, and commissioning steps—then into live EMS logic.
One partner after energisation
Asset integration plus UK energy management software—so DNO compliance and commercial operation are not split across vendors.
How to submit a DNO grid connection request (UK)
The exact portal depends on your distribution network operator, but most UK projects follow the same sequence searchers ask about on Google.
- 1
Find your DNO and check pre-application guidance
Identify your distribution network operator (DNO) by postcode—e.g. via the Energy Networks Association Find My Network Operator tool or by calling 105. Many DNOs offer pre-application support for solar, BESS, EV charging, or larger loads before you submit a formal grid connection request.
- 2
Gather information for the connection application
Prepare site plans, proposed meter location, load or generation details (kVA/kW), technology type (solar, BESS, CHP, wind), and MPAN if you already have a supply. Clear data reduces back-and-forth and speeds your DNO grid connection request.
- 3
Submit the DNO grid connection request
Apply through your DNO’s online portal or application forms—new connections, alterations, and low-carbon technologies each have defined routes. You may use contestable works via an Independent Connections Provider (ICP) for part of the build, depending on scope.
- 4
Review the connection offer and quotation
The DNO assesses network capacity and issues a connection offer—often within roughly 5–15 working days for standard cases, longer for reinforcement. The offer sets import/export limits, point of connection, and costs for any required grid works.
- 5
Accept, energise, and operate within limits
After acceptance and payment, the DNO schedules physical connection. From energisation onward, operations must respect approved export/import limits and G99/G100 where applicable—this is where energy management software keeps you compliant.

DNO grid connection request — FAQ
- What is a DNO grid connection request?
- A DNO grid connection request is your formal application to the UK distribution network operator to connect new load or generation—or to change an existing connection. The DNO reviews capacity, may quote for reinforcement, and issues a connection offer with import/export limits.
- How do I submit a DNO grid connection request in the UK?
- First confirm who your DNO is (postcode lookup or call 105). Then use that DNO’s online application service or forms—submit site plans, load/generation details, and meter information. For contestable works you may involve an Independent Connections Provider (ICP) alongside the DNO process.
- Who is my DNO?
- Your DNO depends on where the site is in Great Britain—for example Electricity North West, Northern Powergrid, SP Energy Networks, or National Grid Electricity Distribution in different regions. Use the ENA Find My Network Operator tool or call 105 to confirm before applying.
- How long does a DNO connection offer take?
- Timelines vary by DNO and project complexity. Straightforward applications are often assessed in roughly 5–15 working days; reinforcement or larger export can take longer. Pre-application discussions help avoid surprises.
- Do I have to use my DNO for all connection work?
- Under UK rules you do not have to use your DNO for all services—contestable connection works may be delivered by an accredited Independent Connections Provider (ICP). The DNO still issues the connection offer and owns the network—you need alignment across parties.
- What happens after my DNO connection is approved?
- After acceptance and energisation, you must operate within approved import/export limits. ArcGrid EMS configures energy management software to enforce those limits while running BESS, solar, and other assets—and supports trading where permitted.
