Generally no. Clean Export Guarantee (CEG) credit for the electricity you export is applied to your ELECTRICITY account, not your gas. On a dual-fuel plan most suppliers keep electricity and gas as separate accounts on different billing cycles — for example, Electric Ireland does not let an electricity export credit pay down a gas balance. A few suppliers may handle a single combined account differently, so it is worth asking yours directly, but the safe assumption is that your solar credit offsets electricity only. To actually cut a gas bill you reduce gas use or move that load onto electricity you generate: a hot-water diverter sends surplus solar to your immersion instead of heating water with the boiler, and longer term a heat pump shifts heating onto electricity you can partly self-supply.
