Why PSSR Inspections Matter for Businesses in Durham

The city of Durham is a historic cathedral city in North East England, built on a peninsula formed by the River Wear. Its origins date back over a thousand years, and it became an important centre of religious and political power following the Norman Conquest. Durham Cathedral and Durham Castle dominate the city skyline and reflect its medieval significance. The city’s unique layout and historic buildings continue to shape its character and influence its economy.

Religion and administration were central to Durham’s early development. For centuries, the city was ruled by the Prince-Bishops of Durham, who had both religious and political authority. This status brought wealth, trade, and employment to the city, supporting craftsmen, traders, and markets. Durham developed as a service centre for the surrounding rural areas, with its economy based on governance, education, and religious activity rather than heavy industry.

Education is now one of the most important industries within Durham. Durham University, founded in 1832, is a major employer and attracts students and academics from around the world. The university supports a wide range of related industries, including research, accommodation, retail, and leisure services. Its international reputation has helped place Durham on the global academic map and contributes significantly to the local economy.

Tourism also plays a major role in Durham’s economy. The city’s historic buildings, museums, riverside walks, and cultural events attract large numbers of visitors each year. Durham Cathedral and Castle are part of a UNESCO World Heritage Site, increasing the city’s appeal to both domestic and international tourists. Tourism supports jobs in hospitality, including hotels, cafés, restaurants, and visitor services.

Unlike many nearby towns, Durham has never been heavily industrialised. Although coal mining was important in the wider county, the city itself has always relied mainly on service industries. Today, public services, healthcare, education, retail, and professional services form the backbone of Durham’s economy. Together, these industries create a stable and diverse economic base that balances the city’s historic heritage with its modern role as a centre for learning and culture.

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 Durham 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 Durham – 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 Durham 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.
