Electrical question

[Business Man]

Is it OK to put 1.00mm twin earth pvc cable in 20mm pvc round conduit above a plasterboard ceiling? This would be a distance of 2 meters from the centre load bearing wall to the light fitting above living room ceiling.

There is no insulation in the ceiling and the lighting circuit is on 6a.

Am I being over cautious in thinking the cable may over heat in pvc conduit with reduced air circulation

It's just to make it easy for any future work really, at the moment the ceiling is down but I'm sure electricians love conduit already in place to make it easier for them.
