Scottish & Southern Electricity Networks DNO Applications
UK DNO application experts for solar, battery storage, EV chargers, and heat pumps connecting to SSEN. We submit, chase, and get approvals, you focus on installing. Every application is tracked in your portal so you always know where it stands.
Timings drawn from applications submitted through the DNO Renewables platform. Not industry-wide figures.
Working with SSEN: what we've seen
SSEN operates two very different licensed areas: the affluent, densely-installed corridor of central southern England, and the vast, sparsely-networked Scottish Highlands and Islands. The portal is shared but the engineering realities are not. A G99 in Hampshire is rarely constrained; the same size system in the Western Isles almost always is.
Where SSEN covers
Scottish & Southern Electricity Networks is the licensed distribution network operator for Central Southern England, North of Scotland.
Postcode areas served: SO, PO, RG, OX, SN, IV, AB, PH, PA, KW, HS, ZE, IM (partial)
Portal & process
SSEN submissions go through the SSEN Portal. We hold direct access and submit under our engineering credentials, so you never need to create a DNO portal account.
Our tip: In constrained rural areas, consider export limiting up front to shorten G99 approval.
What we've learned about SSEN
Two distinct regions: SSEN South (central southern) and SSEN North (Scotland)
Generally responsive with fast G98 turnaround
Detailed protection settings expected on G99
Export limits more common in constrained rural Scottish areas
Why SSEN applications get bounced
Real reasons we see SSEN kick applications back to installers. Fixing these before submission cuts turnaround dramatically.
- 1
Missing G100 documentation on export-limited G99s (SSEN is strict on this)
- 2
Protection relay settings not provided at G99 submission
- 3
Rural applications where the postcode is on-grid but the site is off-grid or private-wire
- 4
Ambiguous MPAN, some rural sites share supplies across multiple buildings
Projects we handle in Central Southern England
The mix of work we submit to SSEN, drawn from the applications flowing through our platform.
High-value domestic solar-plus-battery across Hampshire, Berkshire and Oxfordshire
Commercial solar on Solent logistics and distribution parks
Rural Highland installs where export limiting is common by default
Community energy and small wind projects in island postcodes
How we handle SSEN applications
Every submission is prepared and reviewed by a real DNO engineer before it goes anywhere near the SSEN portal.
Correct routing
We identify G98 vs G99 from per-phase output before submission, no wrong-form rejections.
SLD prepared by experts
Every SLD is drawn by our team and reconciled against the equipment list before submission.
LOA & MPAN verified
The Letter of Authority is checked against the registered account holder for the MPAN.
Proactive chasing
We chase SSEN every 5 working days and respond to information requests the same working day.
SSEN DNO application FAQs
How long does a G98 notification take with Scottish & Southern Electricity Networks?
Based on the applications we submit, G98 notifications with SSEN typically take 1–3 working days. Timings vary with system size, portal backlog, and completeness of the submission.
How long does a G99 application take with Scottish & Southern Electricity Networks?
G99 applications with SSEN typically take 4–8 weeks. Larger commercial systems, export-limited installs, or projects in constrained areas can take longer, especially if network reinforcement is required.
Which portal does Scottish & Southern Electricity Networks use?
Scottish & Southern Electricity Networks uses the SSEN Portal. We submit and manage applications directly through this portal on your behalf under our engineering credentials.
Can I choose to use a different DNO?
No. Your DNO is determined by the geographic location of the installation. Scottish & Southern Electricity Networks covers Central Southern England, North of Scotland, and installers in those areas must submit through them.
Do I need to pay Scottish & Southern Electricity Networks to submit an application?
G98 notifications and standard G99 applications are free from the DNO itself. Costs from SSEN only arise if the network requires reinforcement or you receive a chargeable connection offer. Our service fee is separate, G98 from £50+VAT, G99 from £125+VAT.
Is SSEN North slower than SSEN South?
For G98s no, both regions process quickly. For G99s in the Highlands or Islands, network studies can extend timescales because of long, constrained rural circuits. We factor this into project plans up front.
Do I need export limitation with SSEN in a rural area?
Not automatically, but in constrained Scottish areas offering a G100-compliant export limit up front often shortens G99 assessment significantly. We'll advise per site.
