Episodes of "Holby City" cost around £370,000 to produce. This is more than the BBC soap opera "EastEnders" which costs £130,000 per episode. "Casualty" costs £450,000 per episode. As "Holby City" is a high-volume, year-round production, it has relatively low production costs. Set-up costs can be spread over many years. Sets can be re-used. This is not the case for shorter series or one-off dramas.
