TL;DR:

  • Peer-to-peer (P2P) energy trading lets solar households sell surplus electricity to other consumers directly, typically at better rates than Smart Export Guarantee tariffs which average 4—7p/kWh in 2026
  • Licenced P2P platforms in the UK include Piclo Exchange (wholesale grid market) and community schemes run through local energy co-ops — true consumer-to-consumer trading remains regulated and technically constrained
  • For most households, battery storage + a smart time-of-use tariff (Octopus Agile, Tesla Electricity) still offers better returns than P2P trading today; but P2P is maturing and worth watching if you have significant surplus generation

The Smart Export Guarantee requires licensed energy suppliers to offer payments for surplus solar electricity exported to the grid. Rates in 2026 range from around 4p to 8p per kilowatt-hour depending on your supplier — better than zero, but a fraction of the import price you pay for the same unit of electricity. Peer-to-peer energy trading promises something more interesting: selling your surplus directly to someone nearby who needs it, cutting out the grid middleman and capturing more of the value your panels generate.

The appeal is obvious. The reality is more complicated.

How P2P Energy Trading Actually Works

Genuine consumer-to-consumer electricity trading faces a structural problem: the UK’s electricity system uses shared grid infrastructure, so electricity you export does not literally travel down the wire to your neighbour. Electrons from your roof panels merge with the grid and the equivalent amount is drawn somewhere else.

What P2P platforms do instead is a financial settlement layer. When you export electricity, the platform records it. When a matched consumer draws electricity from the grid, they pay the agreed P2P rate rather than a standard tariff. The physical electricity comes from the same grid mix — the P2P element is an accounting and billing arrangement, not a different physical path.

This matters for setting expectations: P2P does not reduce transmission losses or bypass grid infrastructure. What it does do is allow a different price signal to reach generators and consumers, potentially benefiting both compared to standard export and import rates.

Platforms Operating in the UK

Piclo Exchange is the most established P2P-adjacent platform in the UK, though it operates primarily in the wholesale flexibility market rather than the consumer market. Piclo connects distributed energy resources — battery storage, solar, demand response assets — with Distribution Network Operators (DNOs) who need local flexibility to balance the grid. If you have a sufficiently large battery or generation asset, Piclo is a route to revenues from grid services alongside or instead of the SEG.

Community energy schemes operated by local co-ops (such as Bristol Energy Co-op, Community Energy Wales, and various others under the Community Energy England network) run local P2P arrangements where members sell and buy electricity within the community. These are typically structured as licensed supply through the co-op, with members receiving preferential rates rather than direct bilateral trading.

OVO Energy’s Power Move pilot and similar trials by network operators have tested local P2P arrangements in specific geographic areas, demonstrating that local matching can work technically. Wider rollout depends on regulatory approval and smart meter data availability.

The regulatory position in the UK is that electricity supply to third parties requires a supply licence, which rules out informal household-to-household trading. All functioning P2P arrangements operate through a licensed intermediary — the “P2P” label covers the matching and financial settlement layer, not the physical supply.

Rates Compared to the Smart Export Guarantee

The SEG in 2026 pays:

  • Octopus Energy Export: 4.1p/kWh (Outgoing Octopus fixed rate)
  • Ovo Energy: 5.6p/kWh
  • EDF Energy: 5.5p/kWh
  • E.on Next: 4.5p/kWh
  • Octopus Agile Export: variable, averaging 3—12p/kWh depending on time of day

Community P2P schemes typically offer 8—14p/kWh to generators, with consumers paying 20—25p/kWh (compared to 24—30p/kWh on a standard variable tariff). The spread funds the platform’s operating costs and any co-op overheads. For a solar household exporting 1,000 kWh per year, the difference between 5p/kWh (SEG) and 12p/kWh (community P2P) is £70 annually — meaningful but not transformative.

Who Benefits Most from P2P

High surplus exporters — households with south-facing roofs, large panel arrays, and low daytime consumption — export the most electricity and have the most to gain from higher export rates. If you are already exporting 3,000+ kWh annually, the per-unit rate matters.

Members of active community energy groups — if a local co-op is running a scheme in your area, joining can deliver better rates than the SEG while supporting local energy resilience.

Those with battery storage — combined P2P export with battery storage gives you the option to shift export to higher-rate periods. If your community scheme pays more during evening peak hours, a battery lets you store daytime generation and export when the rate is better.

The Battery Plus Smart Tariff Alternative

Before committing to a P2P platform, model the alternative. Octopus Agile charges 3—5p/kWh for import during overnight off-peak hours and pays 10—15p/kWh for export during the afternoon peak (roughly 4pm—7pm). A battery charged overnight at cheap rates and discharged during peak periods — with solar surplus exported during the afternoon peak — can generate total savings of £300—£700 per year for a well-sized system, often outperforming what a community P2P scheme can offer.

The Tesla Electricity and Octopus Intelligent Flux tariffs extend this further with vehicle-to-grid and home battery integration. If your priority is maximising financial return from solar and storage, the smart tariff route currently has more scale and optionality than P2P.

P2P is a better story for community benefit — keeping money within a local community, supporting smaller generators, and building energy resilience at the neighbourhood level — than for pure financial return.

What is Coming

Ofgem’s Local Energy Markets programme and the Review of Electricity Market Arrangements (REMA) both flag local trading as a long-term objective for the UK energy system. The expectation is that as smart meter data availability improves, half-hourly settlement becomes universal (targeted for completion by 2027), and Distribution System Operators gain more active management capabilities, genuine local energy markets will become viable at scale.

This means P2P in 2026 is a pilot-stage technology in the UK consumer market, not a mature product. The community energy route is the most accessible path today. Keeping an eye on what your local DNO and community energy groups are running is the practical advice for 2026 — national rollout of competitive consumer P2P platforms is still a few years away.

How to Get Started

  1. Find your community energy group — Community Energy England’s map lists active schemes by region. Wales and Scotland have their own networks. Check whether any scheme in your area accepts prosumer members.

  2. Check your smart meter — P2P and local flexibility platforms require a SMETS2 smart meter with half-hourly data sharing enabled. Your supplier can confirm whether your meter is configured correctly.

  3. Calculate your export volume — your supplier’s annual statement shows total export in kWh. This tells you how much the per-unit rate difference actually matters to your household.

  4. Compare against Octopus Agile Export — if you have a battery, run the numbers on Agile Export rates before committing to a community P2P rate. The variable rate can be better than a fixed P2P rate in summer months when your export is highest.

P2P energy trading is a promising model with real uptake in community energy contexts. It is not yet the frictionless solar export marketplace it could eventually become — but for households who want to keep their solar income within the local community rather than feeding it to a national supplier, the community energy route is live and available today.
