For clever guys you lot don't think outside the box very well.
IF what you say is true, and I doubt for one minute the Intergas or Atmos Inter would have a problem being slightly oversized.
You could if it bugs you that much fit a pump over-run type switch, whereas the boiler cuts off for say 15mins on a timer after the room temperature is reach. On a well insulated property you could make it 30mins and probably still not notice the difference.
