The short answer is no, you cannot receive payments for exporting solar electricity to the grid without a smart meter in the UK. Under the Smart Export Guarantee (SEG), all licensed electricity suppliers must require a smart meter to calculate and pay for exported electricity (GOV.UK, 2026). Without one, you have no way to measure export volumes, so you receive no payment.
The key variable is whether you have a smart meter installed and operational. If you generate solar power but lack a smart meter, any surplus electricity you send to the grid is effectively free for the network, you get zero compensation. This applies to all new solar installations after 1 January 2020, when the Feed-in Tariff (FiT) ended. Homes with an existing FiT contract and a working generation meter may still receive payments, but that scheme is closed to new applicants.
Smart Export Guarantee requires a smart meter
Ofgem states that SEG payments are calculated based on half-hourly export data collected by your smart meter (Ofgem, 2026). Without this data, suppliers cannot verify how much electricity you export. The SEG rate varies by supplier, but typical payments range from 3p to 15p per kWh exported. To qualify, you must have a smart meter that meets the Smart Metering Equipment Technical Specifications (SMETS1 or SMETS2).
Older solar systems without smart meters
If you installed solar panels before 2020 and are on the Feed-in Tariff, you can still receive generation and export payments using a dedicated generation meter, no smart meter needed. However, the FiT closed to new applications on 31 March 2019 (Energy Saving Trust, 2026). For any new solar system installed after that date, a smart meter is mandatory to access export payments under the SEG scheme.
Getting a smart meter for solar export
Most suppliers offer free smart meter installations. If you have solar panels but no smart meter, contact your energy supplier to arrange one. The installation is typically straightforward, though some older solar inverter setups may require a generation meter alongside the smart meter. Once installed, your supplier will enable export readings and begin SEG payments (TrustMark, 2026). Expect a wait of up to six weeks for payments to start after installation.
A worked example
A typical 1930s semi-detached house in Manchester with a 4kW solar panel system can export around 2,500 kWh per year to the grid. Without a smart meter, you receive zero payment for this exported electricity. With a smart meter and a typical SEG rate of 8p per kWh from a supplier like Octopus Energy or EDF, you would earn £200 annually. The upfront cost of a smart meter installation is zero under the government’s rollout programme, and most suppliers will fit one within four to six weeks of requesting it. Over 25 years, assuming a modest annual inflation of 2% on electricity prices, total export earnings could reach £6,400. The Energy Saving Trust confirms that households with smart meters and solar panels typically recoup the cost of their solar installation in 10 to 15 years through combined bill savings and SEG payments.
| Item | Figure |
|---|---|
| Upfront cost after grants | £0 (smart meter installation is free) |
| Yearly savings | £200 (SEG payments at 8p/kWh) |
| Payback period | Immediate (no cost to install smart meter) |
| 25-year lifetime savings | £6,400 (assuming 2% annual inflation on export rates) |
What homeowners often get wrong
The most common mistake is assuming you can still receive export payments with a traditional generation meter or a first-generation smart meter that has gone dumb. Here are three frequent errors that cost homeowners money.
- Thinking a generation meter from the FiT era works for SEG Generation meters only measure total electricity produced, not what is exported to the grid. Suppliers require half-hourly export data from a smart meter to calculate SEG payments, so relying on an old FiT meter means you receive nothing for exported power.
- Believing a dumb smart meter still qualifies for SEG If your first-generation smart meter lost its connection after switching suppliers, it no longer sends automatic readings. Without live data, your supplier cannot calculate export volumes, and you will not receive SEG payments until the meter is upgraded or recommissioned.
- Assuming you can switch suppliers and keep SEG payments without a smart meter All SEG-licensed suppliers require a functioning smart meter to pay for exports. Moving to a new supplier without confirming your smart meter is operational and compatible with their system can void your export contract and leave you with zero income from surplus solar power.
Quick reference
- You must have a smart meter to receive any payment for exported solar electricity under the Smart Export Guarantee.
- The average 4kW solar system in the UK exports about 2,500 kWh per year, worth £75 to £375 depending on your SEG rate.
- Smart meter installation is free under the government’s rollout programme and does not affect your solar panel warranty.
- SEG payments are calculated from half-hourly export data collected by your smart meter and verified by Ofgem.
- Homes with a working FiT generation meter and a pre-2020 contract can still receive FiT payments without a smart meter, but this scheme is closed to new applicants.
Frequently Asked Questions
No, you cannot. Ofgem requires a smart meter to measure export volumes under the Smart Export Guarantee.
Your surplus electricity is sent to the grid for free with zero compensation. The Energy Saving Trust confirms no payment is possible without metered data.
No, generation meters only measure production, not export. The Smart Export Guarantee specifically requires half-hourly export data from a smart meter.
No, if you have a pre-2020 Feed-in Tariff contract, you can still receive payments using your existing generation meter. However, this scheme is closed to new applicants.
