Presto is one of the largest Swedish-headquartered fire-safety companies, running fixed-system installation alongside its extinguisher, service and training business from Katrineholm. It holds SBSC certificate 9-551 as anläggarfirma gassläcksystem to SBF 1002:4 and certificate 24-159 as anläggarfirma kökssläcksystem to SBF 2025:1, together with certificate 10-22 as anläggarfirma brandlarm to SBF 1008:3. It appears separately in SVEBRA’s public competence register as employing certified brandtätningstekniker under SVEBRA 2025:4, röklucketekniker under 2023:2 and nödbelysningstekniker under 2024:2 — so its certified scope spans suppression, firestopping, smoke vents and emergency lighting. Its own website sits behind a bot checkpoint, so everything stated here comes from the two registers rather than from the firm’s own copy.
