Yes. Under the UK's Smart Export Guarantee (SEG), licensed suppliers with 150,000+ customers must offer a tariff for surplus electricity you export to the grid. Typical rates are 4-6p/kWh, with some suppliers offering up to 15p/kWh on time-of-use tariffs. You need a smart meter and an MCS-certified installation to be eligible — your supplier will install a smart meter for free if needed. A typical 4kWp system without battery storage exports around 50-70% of its generation, providing a meaningful income stream alongside electricity bill savings.

Based on Norfolk regional data, a 4kWp system generates approximately 3,860 kWh per year at a yield of 965 kWh/kWp, covering 102% of average household use (3,800 kWh/year). The area receives around 1,600 sunshine hours annually. Norfolk ranks #11 of 102 UK counties for solar yield, putting Swaffham in an excellent position for solar energy. Output peaks between May and August and is lower in winter, though annual generation figures already account for this seasonal variation. South-facing roofs at a 30-40° pitch achieve optimal yields, while east or west-facing roofs still produce 80-85% of maximum output.

Get at least 3 quotes from MCS-certified installers to compare pricing, equipment brands, and warranty terms. Check each company is registered with MCS at mcscertified.com — this certification is required for Smart Export Guarantee eligibility. Look for 25-year panel performance warranties and 10-15-year inverter warranties as a minimum. Ensure your installer includes the DNO notification (G98/G99 application) and handles all paperwork. Remember that 0% VAT applies automatically to residential installations, so you should not be charged any VAT on the total cost.

A smart meter is required to sell surplus electricity back to the grid under the Smart Export Guarantee (SEG) and earn 4-6p/kWh for your exports. Your energy supplier will install a smart meter for free if you do not already have one — contact them before or shortly after your solar installation. You do not strictly need a smart meter for the solar panels themselves to work, but without one you cannot receive SEG payments. Your MCS-certified installer submits the G98/G99 application to your Distribution Network Operator after installation to register your system for grid export.
