TfL is aware of only two entire battery packs being replaced since New Routemasters were introduced to London. Batteries are, however, subject to regular maintenance which may require individual modules to be replaced. This performance is in line with batteries on other types of hybrid diesel-electric buses in the fleet.

The cost of replacing current battery packs beyond the warranty period would be circa £25,000. However, when operators bid for route contracts they factor in the anticipated costs of maintaining vehicles over the duration of the operating contract and would bear these costs if they materialised.
