Makeup Water Storage Tank Manufacturer for the UK: UKCA Marking and Post-Brexit Compliance

Since Brexit the UK runs its own conformity regime alongside CE, so a makeup water storage tank manufacturer for the UK must navigate UKCA marking and the UK's adoption of BS EN standards, plus UK water regulations that are strict about backflow and potable contact. A UK-site tank is therefore a compliance exercise as much as an engineering one. This article covers the post-Brexit requirements for a UK makeup tank.

UK conformity now centers on UKCA marking, with structural steel execution to BS EN 1090 and CE still accepted in the transition; the shell, anchor, and foundation are calculated to Eurocode for UK site loads. Confirm which mark your project specifies and the execution class, because UK buyers expect the documentation.

• UKCA (CE in transition).
• BS EN 1090 execution.
• Eurocode UK loads.
• Confirm mark + class.

UK water fittings law is strict about backflow and potable contact, so a make-up tank that connects to the mains needs WRAS-approved materials and backflow prevention (typically a reduced-pressure zone or air gap). Where the water is potable-grade, the lining and fittings should carry WRAS or equivalent approval.

• WRAS-approved materials.
• Backflow prevention.
• RPZ or air gap.
• Potable approval.

The UK is wet and temperate with coastal marine influence, so specify GFS or FBE with a holiday test and a chemical-resistance list, with extra attention on exposed coastal or island sites. The lining, not the steel, decides the tank's decades of service in damp air.

• Wet, temperate climate.
• GFS or FBE holiday-tested.
• Coastal extra attention.
• Lining beats steel.

Beyond WRAS, potable or semi-potable make-up needs a clean inert lining and a monitored level to the site system, so the tank is controlled rather than a silent risk. Compliance and monitoring together keep a UK-site tank both legal and reliable.

• Clean inert lining.
• Level monitored.
• Legal + reliable.
• Controlled asset.

We have no UK or data-center project in this library. Our Italian and French deliveries cited (Sardinia 30,549 m3 2025, Guadeloupe potable GFS 2024) are analogous European proof of our EN 1090-aware, coated-tank capability, not UK or data-center deliveries.

• No UK / DC project.
• Citations analogous, not claims.
• EU EN 1090 capability real.
• UKCA needs your project.

UKCA marking, with CE still accepted in the transition; confirm which your project specifies, plus BS EN 1090 execution with a stated class.

The Water Supply (Water Fittings) Regulations: WRAS-approved materials and backflow prevention (reduced-pressure zone or air gap) for any tank connected to the mains.

Glass-fused-to-steel or fusion-bonded-epoxy, holiday-tested, with extra attention on coastal or island sites in the wet, temperate climate.

Yes, WRAS or equivalent approval on lining and fittings, plus EN 1717-class backflow protection where connected to potable mains.

Not in our project library. We cite real Italian and French deliveries as analogous European proof of our EN 1090-aware coated-tank capability.

Not in our project library. Our cited tanks are analogous critical-infrastructure storage, not data-center deliveries.

A makeup water storage tank manufacturer for the UK must meet the post-Brexit baseline, UKCA marking (with CE in transition) and BS EN 1090 execution with Eurocode loads, and then satisfy strict UK water law: WRAS-approved materials and backflow prevention for any mains-connected make-up tank. The wet, marine climate calls for a holiday-tested GFS or FBE lining, and potable-grade make-up adds approval and monitoring. Confirm the mark, the execution class, and WRAS compliance, because in the UK the documentation is checked as carefully as the steel.
