Siemens
Sister brand to Bosch, built on the same platforms, so faults, parts and error codes are closely related. Typical repair cost for a Siemens cooker: £80–£190.
Most Siemens cooker repairs cost £80–£190 including parts and labour. Prices depend on the fault and parts availability.
Switches, rings, burners, igniters and thermocouples are cheap repairs. Gas work must only be done by a Gas Safe registered engineer. Induction generator faults on older hobs can approach replacement cost.
The model and serial number are on a rating plate — typically inside the door frame, on the back panel, or inside the fridge on the side wall. Quote it when booking a repair so the engineer brings the right parts.
