UK Fuse Energy SEG Export Tariff Guide: Rules and Setup

Key Takeaways

• Fuse Energy Supply Limited is officially classified by Ofgem as a mandatory Smart Export Guarantee licensee for the seventh SEG year from 1 April 2026 to 31 March 2027.
• Mandatory licensee status places Fuse Energy alongside major UK energy suppliers obligated to offer export remuneration to domestic generators.
• The statutory scheme covers renewable installations across Great Britain up to a maximum capacity of 5MW, or up to 50kW for micro-CHP.
• Statutory regulations dictate that SEG tariff rates must always be above zero, with payments settled directly via half-hourly export meter readings.

What Are Fuse Energy's Obligations Under the Smart Export Guarantee?

The Smart Export Guarantee is the statutory framework governing export remuneration for small-scale low-carbon electricity generators across England, Scotland, and Wales. The SEG launched on 1 January 2020 and is a government-backed initiative designed to replace the legacy Feed-in Tariff export mechanism. Under energy market regulations administered by Ofgem, licensed electricity suppliers crossing domestic customer volume thresholds are designated as mandatory licensees.

For the seventh SEG year from 1 April 2026 to 31 March 2027, Ofgem published its official licensee register confirming that Fuse Energy Supply Limited has joined the ranks of mandatory electricity suppliers. In the statutory register, Fuse Energy is categorized under Current mandatory SEG Licensees, obligating the company to provide an open, transparent export tariff to eligible microgenerators.

This classification elevates Fuse Energy into the established cohort of major suppliers providing statutory export routes. Homeowners can benchmark market-wide licensee offerings in our comprehensive UK SEG export tariff tracker report.

The Seventh SEG Year Cohort: Mandatory and Voluntary Licensees

Ofgem categorizes participating electricity suppliers into two distinct statutory tiers based on customer numbers and voluntary participation declarations. Mandatory licensees are legally compelled to maintain an open export tariff, whereas voluntary licensees opt into the scheme to support low-carbon generators.

In the official list of licensees who advised Ofgem that they are Smart Export Guarantee licensees for the seventh SEG year from 1 April 2026 to 31 March 2027, Fuse Energy shares mandatory standing with the largest suppliers in Great Britain:

Scheme Eligibility: 5MW Capacity Limit and Geographic Boundaries

To successfully register for an export tariff with Fuse Energy or any mandatory licensee, a microgeneration installation must satisfy strict statutory parameters established by Ofgem:

1. Eligible Technologies: The scheme is open to anyone with an installation of one of the following technology types up to a capacity of 5MW, or up to 50kW for micro-CHP. While solar photovoltaic (solar PV) systems represent the vast majority of applicants, onshore wind, hydro, and anaerobic digestion are also eligible.
2. Geographic Scope: Installations must be located in Great Britain and meet the applicable eligibility criteria. Systems located in Northern Ireland operate under separate regional electricity market arrangements.
3. Certification Standards: Domestic arrays under 50kW must demonstrate microgeneration certification, confirming that hardware and installer workmanship adhere to rigorous engineering standards.
4. Grid Permission: Generators must hold a formal grid connection notification letter from their local Distribution Network Operator (DNO).

Commercial Pricing Discretion and the Statutory Price Floor

Under the governance rules of the Smart Export Guarantee, Ofgem does not set a universal, fixed pence-per-kilowatt-hour rate across all suppliers. Instead, SEG Licensees determine the rate, contract length and other terms which SEG Generators will receive.

This regulatory flexibility allows suppliers to design fixed or variable tariffs tailored to customer segments. However, consumer protection is maintained through a fundamental statutory safeguard: SEG tariff rates must always be above zero. This rule ensures that a supplier can never charge a microgenerator for spilling excess clean solar electricity back onto the distribution network.

Because commercial terms remain at licensee discretion, generators thinking of applying for a SEG tariff should shop around to see which tariff is best for their individual circumstances. Microgenerators can contract their export with an alternative supplier without moving their import electricity account, providing freedom to select the highest export rate.

Export Metering and Settlement via Export MPAN

Underpinning all Smart Export Guarantee payments is automated half-hourly export data collection. Under Ofgem regulations, SEG payments are calculated by using export meter readings.

To achieve automated billing settlement, applicants must establish an operational export infrastructure:

• Smart Meter Communication: Properties must feature an operational smart meter capable of logging electricity exports in half-hourly increments and communicating data via the national Data Communications Company (DCC) network.
• Export MPAN Creation: The local Distribution Network Operator must generate a unique Meter Point Administration Number specifically for electricity export. This export MPAN links the physical meter to central national settlement databases.
• Reading Verification: Licensees retrieve automated half-hourly meter logs from the data collector to calculate monthly or quarterly credit disbursements.

By qualifying as a mandatory licensee for the seventh SEG year running from 1 April 2026 to 31 March 2027, Fuse Energy delivers a modern, app-integrated platform for Great Britain homeowners seeking statutory returns on their rooftop solar photovoltaic arrays.
