SEG Registration Scotland — Get Paid for Your Solar
The Smart Export Guarantee pays you for every unit of surplus solar electricity you export to the national grid. It is a government-mandated right for every MCS-certified solar owner. Scottish Energy Efficiency registers every customer as standard — export payments begin from day one.
SEG at a Glance
What Is the Smart Export Guarantee?
The SEG is your legal right to be paid for solar electricity you return to the grid. Understanding how it works ensures you choose the best tariff and maximise your returns.
The Smart Export Guarantee was introduced by the UK Government in January 2020 as a replacement for the Feed-in Tariff. Under SEG, obligated energy suppliers — those with 150,000 or more domestic customers — are required by law to offer export tariffs to eligible small-scale generators.
For solar owners in Scotland, this means receiving a payment for every kilowatt-hour of electricity your panels generate but do not use within your home — the surplus exported back to the national grid via your smart meter.
Unlike the Feed-in Tariff, which was set by government at a fixed rate, SEG rates are determined by each individual supplier. This creates competition between providers and means rates vary — from around 3p to over 15p per kWh depending on the tariff and provider.
The key difference from the old FiT is that SEG only pays for what you actually export. There is no assumed export payment — a smart meter reads your actual export and you are paid only for verified exported units.
SEG vs Feed-in Tariff
The Feed-in Tariff closed to new applicants in March 2019. Every new solar installation must use the Smart Export Guarantee for export income. There is no alternative route for new installations.
MCS Certificate Is Non-Negotiable for SEG
Without a valid MCS certificate from an MCS-certified installer, every SEG licensee in the UK will reject your application. There is no workaround.
- Verify your installer at mcsinstallers.co.uk BEFORE signing any contract
- The MCS certificate is issued on installation day — ask for it specifically
- Keep your certificate safe — you will need it for SEG and if you ever sell your home
- If an installer cannot tell you their MCS number, do not proceed
Best SEG Tariffs in Scotland 2026
SEG rates are set by individual suppliers and change regularly. Here is a comparative guide to the main tariff types available in 2026 and what suits different types of solar owners.
Fixed Rate SEG
3p – 7p / kWh
Best for: Simpler setups without batteryA fixed payment per kWh regardless of time of day or demand. Predictable income, easy to calculate annual earnings. Works well for systems without battery storage where export timing cannot be controlled. Good entry-level option.
Octopus Intelligent Flux
Dynamic — market linked
SEE Standard — RecommendedA fully dynamic import/export tariff designed for solar owners. Pays variable rates for export based on grid demand — higher rates during morning and evening peaks when the grid values solar export most. Also offers reduced import rates during overnight off-peak windows.
Variable Rate SEG
1p – 15p+ / kWh
Best for: Battery storage ownersVariable rate tariffs track wholesale market prices or grid demand signals. When grid demand is high — typically morning and evening peaks — rates can be significantly higher than fixed tariffs. Battery storage enables strategic export during high-rate windows.
Rates are indicative as at March 2026 and subject to change. Always verify current rates directly with providers before making decisions.
Octopus Flux — Why SEE Recommends It
Scottish Energy Efficiency registers every customer with Octopus Intelligent Flux as standard. Here is why we chose it as our recommended tariff for Scottish solar owners.
Dynamic Export Rates
Flux pays variable export rates that peak during morning (7–9am) and evening (4–7pm) demand windows. Exporting during these periods can earn significantly more per kWh than flat-rate tariffs offer.
Off-Peak Import Savings
The other side of Flux is cheap overnight import rates. If you have battery storage, you can charge from the grid cheaply overnight and use that stored energy — reducing what you import during expensive peak periods.
Designed for Solar + Battery
Flux is engineered specifically for homes with solar panels. Even without battery storage, the export rate uplift at peak times can meaningfully increase annual SEG earnings compared to a fixed-rate tariff.
Monthly Payment
Export earnings are paid monthly directly into your account. A transparent online dashboard shows your generation, export, import, and earnings in real time.
Flux Tariff Structure
Exact rates are dynamic and vary. Check octopus.energy for current rates before switching.

SEG + Battery Storage — The Winning Combination
Battery storage dramatically changes how you interact with the SEG. Without a battery you export whatever your system generates in excess of your immediate consumption. With a battery, you can choose when and how much to export.
Solar Only (No Battery)
Export happens automatically whenever your panels generate more than you are consuming at that moment. You have no control over when export occurs, so with a fixed SEG rate this is straightforward but with a variable rate you may miss peak-rate export windows.
Solar + Battery Storage
With battery storage, excess solar generation first charges your battery. When the battery is full, remaining surplus exports. You can also programme export timing to align with peak SEG rate windows — and import cheaply overnight if on a dynamic tariff like Octopus Flux.
Battery Storage Significantly Boosts SEG Returns
A typical 10kWh battery storage system added to a 4kW solar installation can increase total annual financial benefit from approximately £600–£800 to over £1,000–£1,200 per year when combined with an optimised dynamic tariff.
How to Register for SEG in Scotland
The full SEG registration process from installation to first export payment. When you use Scottish Energy Efficiency, we handle steps 1–4 on your behalf.
Get Your MCS Certificate
Your MCS-certified installer issues your MCS certificate on installation day. This is your proof of a compliant installation and is the gateway to SEG. Keep it permanently — you will need it if you ever move home.
Confirm DNO Notification
G98 or G99 DNO notification must be submitted. The MCS process confirms this has been completed. Without it, MCS certification is not complete and your SEG application will fail.
Confirm Smart Meter
A smart meter must be installed at your property. If you do not have one, contact your energy supplier to request installation. Your supplier is legally required to offer one at no cost.
Choose and Apply to SEG Provider
Select a SEG licensee and submit your application with MCS certificate details, system size, installation address, and meter serial number. Most major suppliers offer online applications.
Provider Confirms Registration
Your SEG provider confirms your application, validates your MCS certificate, and registers your meter for export measurement. This typically takes 2–4 weeks.
Receive Export Payments
Once registered, export payments begin based on actual smart meter readings. Most providers pay monthly. You can track your export and earnings via your provider's online portal.
How to Switch SEG Provider
You are never locked into a SEG provider. If rates improve elsewhere or a better tariff structure becomes available, switching is straightforward.
Compare Current Rates
Check current SEG rates across obligated suppliers. Key providers include Octopus Energy, British Gas, EDF, E.ON, and OVO Energy.
Apply to New Provider
Visit the new provider's SEG application portal. You will need your MCS certificate number, system size, installation address, and smart meter serial number.
New Provider Validates
The new provider validates your MCS certificate and registers your meter for export measurement. This typically takes 2–4 weeks.
Old Provider Notified
Your old SEG arrangement ends when the new one begins. You will receive a final payment for any exports made before the switch date.
No Penalties for Switching
There are no fees or penalties for switching SEG provider. The government scheme is designed to ensure competition between suppliers. Review rates annually and switch if a better offer is available.
