G98 (Engineering Recommendation)
By Priya Nair · Last reviewed The UK's connection standard for small grid-tied generators up to 16 A per phase, administered through Distribution Network Operators (DNOs). The UK's planned plug-in solar route is being built through amendments to G98 and BS 7671, with a sub-800 W product specification under consultation.
Why it matters
G98 is where UK plug-in legality will actually be decided — the government announcement set the direction, but the amended engineering recommendation and its commencement date are what will make socket connection permitted. Until then, UK buyers should treat the route as proposed, not in force.
