Solar Panels
Solar panels produce energy and reduce your carbon footprint. We’ll help you install solar panels on your site.
Export PPA
Sell exported electricity through either market-linked pricing or a fixed export rate.
Export Meters
If your business is generating excess energy, installing an export meter is the key to unlocking additional revenue.
ENERGY METERS > SMART EXPORT GUARANTEE
Smart Export Guarantee Explained
The Smart Export Guarantee (smart export guarantee) is the UK scheme that allows businesses and homeowners to earn money for surplus electricity exported back to the grid from solar panels or other renewable generation.
If your business has solar installed, or is considering a new system, choosing the right export arrangement is essential to maximising returns. The difference between available tariffs can significantly impact your annual income.
At Flame Energy, we help businesses secure the best SEG tariff and ensure export systems are correctly set up for accurate payments and long-term optimisation.
What is the Smart Export Guarantee (SEG)?
The Smart Export Guarantee (SEG) is a government-backed obligation that requires licensed electricity suppliers to pay for electricity exported to the grid from eligible renewable systems.
It replaced the Feed-in Tariff export payments for new installations and is now the standard route for earning export revenue in the UK.
To qualify, most systems require:
- MCS-certified installation
- Smart (SMETS2) meter capable of half-hourly export data
- Registered export MPAN
- Active SEG agreement with an approved supplier
Best SEG Rates in the UK
The best SEG rates vary between suppliers and depend on your system type, export profile, and whether you have batteries or flexible export capability.
In general, SEG rates in the UK typically range from low single digits per kWh up to higher fixed or time-of-use tariffs for optimised systems.
Smart Export Guarantee Rates Explained
Smart export guarantee rates are not fixed by government. Instead, suppliers set their own export prices, meaning rates can vary significantly between contracts.
Common tariff structures include:
- Fixed export rates (p/kWh regardless of time)
- Variable export rates linked to wholesale pricing
- Time-of-use tariffs with higher peak export pricing
- Battery-optimised export tariffs
Because of this variation, selecting the right tariff structure is just as important as the solar installation itself.
Choosing the Best SEG Tariff for Your Business
The best SEG tariff for your organisation depends on how and when your system exports electricity.
Key factors include:
- Size of solar PV system
- Daytime vs evening consumption patterns
- Whether battery storage is installed
- Export volume consistency
- Supplier eligibility criteria
Businesses with batteries or flexible energy management systems can often access higher-value export opportunities by shifting export to peak demand periods.
Export Setup and Metering Requirements
To receive SEG payments, your system must be correctly configured.
This includes:
Export Meter
An export meter measures how much electricity is sent back to the grid. Most commercial systems use half-hourly smart metering to ensure accurate settlement.
Export MPAN
Your export MPAN is the unique reference number used to register your export connection and enable payment from suppliers.
Without a valid export MPAN, export payments cannot be processed.
How to Maximise SEG Income
Simply exporting electricity is not always enough to maximise value. Businesses can increase returns by:
- Installing battery storage to shift export timing
- Optimising self-consumption to reduce imports
- Reviewing tariffs regularly as rates change
- Aligning export strategy with wholesale price periods
- Ensuring correct metering and settlement setup
A structured approach to export management can significantly increase lifetime solar returns.
