Why parts lead times vary between boiler repairs
Some boiler parts are commonly stocked and available almost immediately, while others — particularly for older or less common models — need ordering directly from the manufacturer and can take longer to arrive. This affects how quickly a diagnosed fault can actually be resolved.

Where parts lead times usually comes from
Frequently replaced components such as common sensors, pumps or PCBs for popular current models are often available quickly through normal supply channels. Parts for discontinued models, less common brands, or components affected by wider supply issues can take longer, and this is communicated clearly once a diagnosis identifies what's actually needed.

- Discontinued or less common model parts can take longer to source
