Why PSSR Inspections Matter for Businesses in Derby

Derby is a prominent city in the East Midlands of England, known for its rich industrial heritage and strong engineering roots. Situated on the River Derwent, Derby became one of the birthplaces of the Industrial Revolution, thanks to pioneering developments in textile manufacturing, particularly at the historic Lombe’s Mill. The city gained prominence in the 19th and 20th centuries as a major centre for rail and engineering, laying the foundation for its continued industrial relevance today. Its central location and excellent transport connections make it a strategic hub for both national and international businesses.

One of Derby’s most defining industries is aerospace engineering. The city is home to Rolls-Royce, one of the world’s leading aerospace and defence companies, which employs thousands of people locally. Rolls-Royce’s operations in Derby focus on the design, manufacture, and maintenance of jet engines, and the company plays a crucial role in the city’s economy and global reputation. In addition, Bombardier (now part of Alstom) has long maintained a major train manufacturing facility in Derby, making it the UK’s leading site for railway rolling stock production. This has earned the city a strong reputation in both the aerospace and rail sectors.

Beyond advanced manufacturing and transport engineering, Derby has a growing presence in the creative, digital, and professional service industries. The city supports innovation through institutions such as the University of Derby, which partners with local businesses to provide research and workforce development. Retail, hospitality, and logistics also contribute significantly to the economy, particularly through hubs like the Derbion shopping centre and nearby industrial estates. Overall, Derby combines deep industrial expertise with forward-looking innovation, making it one of the UK’s key centres for high-skill, high-tech industries.

Derby is surrounded by a range of towns and villages that have played an important role in the city’s industrial development. Places such as Ilkeston, Heanor, and Ripley to the north and west grew rapidly during the 19th century due to coal mining, ironworking, and engineering. These settlements were closely connected to Derby through canals, railways, and later roads, allowing raw materials and finished goods to move easily across the region.

To the south and east, towns and villages including Swadlincote, Melbourne, and Borrowash combined industry with agriculture. Swadlincote became well known for its coal mining and brickmaking industries, supplying building materials across the Midlands. Other villages supported lace making, textile work, and small-scale manufacturing, often alongside farming, reflecting a more mixed local economy.

In more recent times, traditional heavy industry has declined across the area, but new industries have taken its place. Business parks, logistics centres, and advanced manufacturing now provide employment, supported by Derby’s strong links to engineering and transport. The surrounding towns and villages continue to reflect Derbyshire’s industrial heritage while adapting to a more modern and diverse economy.

For these businesses, staying compliant with the Pressure Systems Safety Regulations 2000 (PSSR) is not just a legal requirement—it’s also about safeguarding your employees, protecting your business reputation, and ensuring your equipment remains safe and reliable.

Legal Requirements Under PSSR 2000

PSSR regulations place strict duties on business owners and equipment operators. Any business in Derby that owns or operates pressure systems and pressure equipment must ensure that:

• Pressure systems and pressure equipment is safe to use.

• A written scheme of examination (WSE) is produced prior to their pressure system being put into service.
• A WSE is required when the pressure volume of the vessel exceeds 250 bar/litre (Pressure x Volume), and a relevant fluid is present, or if there is steam stored in the vessel at any pressure.

• Examinations are carried out in line with their written scheme of examination (WSE) and at regular, legally required intervals.

• Inspections are conducted by a competent and impartial person.

Failure to comply can lead to heavy fines, prosecution, and serious safety risks.

Protecting Your Workforce and Your Business

At SEIS, we know that every business in Derby – whether in heavy industry, healthcare, education, catering or automotive—depends on reliable, safe equipment. Regular PSSR inspections & PSSR testing reduces the risk of accidents, protects your workforce, and ensures smooth day-to-day operations. Compliance not only keeps you legal, but also demonstrates a strong commitment to employee safety.

What is a Thorough Examination and In Service Examination under PSSR?

A thorough examination & in service examination under PSSR is a detailed and legally required inspection of your pressure system, and the vessels & system protective devices within it. Unlike simple checks or maintenance tasks, a PSSR examination must be performed by an impartial, competent person and results in an official Report of Thorough Examination.

Frequency of Examinations

How often your pressure system in Derby needs to be inspected & tested depends on its drafted written scheme of examination by the competent person, it’s relevant fluid and the system conditions:

• Every 12 to 14 months – Steam and hot water boilers operating under variable service conditions, and pressure vessels where rapid deterioration can be expected, as outlined in SAFed PSG 01.

• Every 24 to 26 months – Steam and hot water boilers operating under steady conditions, and pressure vessels potentially subject to rapid deterioration, as outlined in SAFed PSG 01 (e.g., Air receivers not regularly drained, shot blast vessels, Autoclaves & Steam jacketed pans).

• Every 26 to 48 months – Watertube steam boilers operating under the highest level of supervision, Pressure vessels not expected to deteriorate to danger within the examination frequency, as outlined in SAFed PSG 01 (e.g., Welded or solid drawn air receivers which are well maintained and regularly drained, Steam receivers associated with boilers on the same examination interval).
• Every 48 to 72 months – Pressure vessels not susceptible to significant deterioration, as outlined in SAFed PSG 01 (e.g., Air/oil receivers, Carbon dioxide storage vessels, Ammonia vessels abscent from stress corrosion cracking).
• Every 120 to 144 months – Examination intervals of 120-144 months would be appropriate for pressure vessels where there is extensive,
  documented experience of satisfactory operation for extended periods without deterioration, as outlined in SAFed PSG 01 (e.g., Stainless steel brewing vessels, class C compressed liquefileable gas and process vessel).

• After significant changes or repairs – Equipment must be inspected immediately if it has been modified, damaged, repaired or relocated.

• It should be noted that consideration should be given to an interim in-service examination under normal operating conditions at the mid-point of any examination period that exceeds 12-14 months.
