Pressure Systems

Deterioration, leaks, abnormal operation, an examination finding or a proposed alteration can require attention. Establish the system boundary and substance contained before selecting the task. Pressure alone does not provide a complete description of the hazards or the legal arrangements applying to an installation.

Tell us what needs doing

What the work can include

Work covers the agreed assessment, maintenance, preparation and remedial activities for the identified system. The instruction distinguishes equipment care from examinations and decisions reserved to the appropriate competent person. Records connect completed work to the equipment, operating information and outstanding examination or repair actions.

The instruction identifies the service boundaries and the information expected at completion. Any additional finding receives a clear next action, so a completed visit does not hide work still required elsewhere in the system.

Important technical decisions

The Pressure Systems Safety Regulations apply to qualifying systems containing a relevant fluid, subject to their scope and exceptions. HSE identifies steam at any pressure and gases under pressure among relevant fluids. Do not assume that every pressurised water loop has identical written-scheme requirements.

Where required, a suitable written scheme of examination must be in place and examinations completed in accordance with it. Routine servicing does not replace that process. Changes to equipment or operating conditions must be considered against the system information and the examination arrangements before the system is returned to use.

Assessment and preparation

Provide the equipment identification and all pressure-system records held with the property. Establish who is the user or owner responsible for the installation and who controls access. If equipment is shared, confirm the manager authorising preparation, repairs and any interruption.

Photographs from normal accessible positions help explain the equipment and working space. Do not remove covers to obtain them. Tell us about tenant availability, protected finishes and the route through the building before arranging the visit.

How the work proceeds

We establish the system and the required maintenance or remedial instruction, coordinating with the relevant examination requirements. Work proceeds under the agreed isolation and access arrangements. Handover records the completed task, any changed equipment details and the actions still needed before use.

The property instruction identifies the affected rooms, any shared-service permissions and the person approving additional work. At handover, the owner receives the practical operating information and a record to pass to the next occupier or maintenance contractor.

Cost, timing and disruption

System type, condition, access, examination preparation and the extent of remedial work affect cost. Depressurisation, cooling and dismantling can influence the programme. Agree the separate responsibilities for examination, maintenance and authorising use so the schedule includes each necessary step.

Agree occupant notices, access, protection and making good alongside the mechanical task. Where the owner is remote, nominate a local contact and a clear approval route so a finding during the visit can receive a prompt, informed decision.

Property and sector applications

Managing agents need equipment responsibility and repair authority recorded. Residential blocks need individual premises distinguished from shared plant. Retail and hospitality need work coordinated with occupants, stock and customer areas. Our full service and project offering supports all sectors, from targeted equipment work to coordinated alterations within a property.

Local coverage

We cover Northumberland, Tyne and Wear, County Durham and Tees Valley, including Berwick-upon-Tweed, Alnwick, Morpeth, Hexham, Newcastle, Gateshead, Sunderland, Durham, Darlington, Hartlepool, Stockton-on-Tees and Middlesbrough. View all locations.

For more than one property, provide the address and equipment details for each. Shared ownership does not mean every building has the same installation or access arrangements.

Frequently asked questions

Does every pressurised water system require the same examination?

No. Applicability depends on the equipment, fluid and regulatory scope. Assess the actual system rather than apply a rule based only on a pressure gauge.

Is an annual service a written-scheme examination?

No. They have different purposes. Where examination is required, it must follow the suitable written scheme.

Can a component be changed without updating records?

The change must be considered against system suitability, operating information and applicable examination arrangements. Keep records consistent with the installed equipment.

What if the property has no written scheme records?

Establish whether the equipment requires one and involve the appropriate competent person. Do not treat a maintenance receipt as a substitute for missing examination arrangements.
