🔍 5. Inspection, Certification & Registration
The Act establishes a statutory chain involving the Chief Inspector, Deputy Chief Inspectors, Inspectors, competent authorities, inspecting authorities and competent persons.
The Chief Inspector, Deputy Chief Inspectors and Inspectors may also advise owners regarding proper maintenance and safe working of boilers.
🏭 6. Conditions Before Manufacture
A boiler or boiler component cannot be manufactured unless the statutory conditions are met.
Manufacturing premises must have specified design and construction facilities. Design and drawings require certification by the inspecting authority. Materials, mountings and fittings must conform to prescribed specifications, and persons undertaking welding must hold the required welders certificate.
🏗️ 7. Inspection During Erection
An owner intending to register a boiler must engage an inspecting authority for inspection at the erection stage. The inspecting authority follows the prescribed inspection and certification procedure.
Where erection conforms to the applicable standards, a certificate of inspection is granted. Where it does not conform, the inspecting authority may refuse certification after directing the required modifications or rectifications and recording the reasons where the deficiencies remain uncorrected.
🛠️ 8. Conditions for Repair
The Act sets conditions before repair of boilers and boiler components. Repair premises must have prescribed facilities, design and drawings must meet applicable standards, and repair materials, mountings and fittings must meet specified requirements.

On registration, a certificate authorising use may be granted for a period not exceeding twelve months and at a maximum pressure specified by the Chief Inspector. A specified economiser or unfired boiler integral to a processing plant may be authorised for up to twenty-four months under the condition stated in the Act.

🕒 Legislative Timeline
The development of India's boiler-safety legislation can be understood through four important milestones: the original Boilers Act, the major 2007 amendment, its subsequent regulatory implementation and the Boilers Act, 2025.
The original statutory framework for the regulation of boilers in India. The Act was enacted on 23 February 1923 and provided provisions relating to the registration, inspection, certification and safe use of boilers.
Act No. 49 of 2007, dated 12 December 2007, introduced important changes relating to competent persons, inspecting authorities, competent authorities, welder certification, manufacture, erection, inspection and repair of boilers and boiler components.
A Gazette notification dated 7 October 2010 brought the specified remaining provisions associated with the 2007 amendment into operation. The framework included provisions connected with recognised Inspecting Authorities and Competent Persons for boiler inspection and certification.
Act No. 12 of 2025, enacted on 4 April 2025, provides the current statutory framework for the regulation of boilers, safety of life and property from boiler explosions, and uniformity in registration and inspection during manufacture, erection and use.
The Act came into force from 1 May 2025 and repealed the Boilers Act, 1923, subject to the savings and transitional provisions provided in the Act.
⚙️ 16. Premium Boiler Compliance Process
The Act links boiler compliance to a controlled sequence of design, manufacture, inspection, erection, registration, certification, use, renewal and alteration controls.
