First fix plumbing refers to the initial stage of plumbing installation that happens before walls, floors, and ceilings are finished — usually during the construction or renovation phase of a building.

🔧 What’s Included in First Fix Plumbing:

• Running pipework for hot and cold water supply.

• Installing waste pipes and soil stacks.

• Fitting pipework for heating systems (radiators, underfloor heating, boiler connections).

• Setting up pipe runs to kitchens, bathrooms, and utility areas.

• Positioning and securing plumbing points (for sinks, toilets, baths, etc.), ready for later connection.

🚫 What’s Not Included:

• No final fixtures or fittings — so no taps, sinks, toilets, showers, or radiators yet.

• No final testing or commissioning.

🏗️ When It Happens:

• After the building’s structure is up (walls, floors, roof).

• Before plastering, tiling, and decorating.

Second fix plumbing is the final stage of a plumbing installation — it comes after plastering, tiling, and decorating are complete. This is when the plumbing system is finished off, connected, and made ready for use.

🔧 What’s Included in Second Fix Plumbing:

• Installing and connecting sanitaryware: sinks, toilets, baths, showers, taps, etc.

• Fitting radiators and connecting them to the heating system.

• Connecting boilers, cylinders, and controls.

• Installing kitchen appliances like dishwashers or washing machines.

• Final leak testing, flushing, and commissioning the system to make sure everything works properly.

🏗️ When It Happens:

• After all the first fix pipework is in place and walls are finished.

• Just before the property is ready to hand over or move into.

🧱 Difference Between First and Second Fix:

• First fix = hidden pipework and preparation (before walls are finished).

• Second fix = visible fittings and connections (after decoration).

It depends on the size and complexity of the job. A simple bathroom or kitchen installation can take just a few days, while a full house fit-out (including heating) may take a few weeks. We’ll always provide a clear schedule before any work begins.
