Plumbing and electrical installations

Plumbing renewal can cover water supply pipes, drainage connections and points of use in kitchens, bathrooms and other areas of a property. The enquiry should distinguish replacement of a pipe section, changes to connection points and more extensive renewal of the internal services.

Identify the connected fixtures, known routes and parts you would like to retain. If you have observed leaks, stains or problems in use, describe where and when they occur. The works need to be defined from an assessment of the existing installation; a visible change to a fixture does not establish the condition of all the concealed pipework. Connections to shared building services need to be identified when defining the intervention.

Replacing a toilet, washbasin, tap, bath or shower tray can be defined as a specific piece of work. To prepare your enquiry, send photographs of the existing fixture and the dimensions and model of the replacement, if already selected. Connection positions, fixing arrangements, access and junctions with finishes need to be clarified.

The proposal should state who supplies the fixture and which removal, adaptation, connection and making-good works are included. Where the change also involves the layout, finishes or other parts of the room, the overall scope should be considered as a bathroom renovation. Replacing an item should not leave the additional work it depends on undefined.

For electrical work, start with the intended use: equipment to be powered, lighting, sockets and controls you want to retain, add or move. The proposal can identify work to wiring, cable routes, fittings and the distribution board, according to the assessment and scope defined for the property.

A list of the points you would like helps prepare the enquiry, but needs to be considered alongside the existing installation and planned equipment. Send available model details and any existing drawings. The extent of renewal and the parts to be retained should be clear, including opening up, closing and making good along the routes involved.

Plumbing and electrical work interact with furniture layouts, equipment, partitions and finishes. Before walls are closed or finishes applied, the intended positions and sequence of the included works need to be clear. In a kitchen or bathroom, these decisions should follow the drawings and dimensions of the items to be fitted.

Tell us whether the property will remain occupied. Planned water or electricity interruptions, access and protection of adjoining areas need to be considered when organising the works. The scope should also define making good: work to a pipe or cable route does not automatically establish that the whole affected wall or floor will be renewed.

Design of building water supply and drainage systems, and design of electrical installations, sit within Engineering. If designs already exist, send the available versions to help define the installation work. If this support still needs to be arranged, it can be included in the same proposal, with the deliverables of each service identified.

When preparing the work, the materials and equipment to be supplied, planned checks and included handover documentation should be clear. At completion, the review of the work should refer to that scope, including any outstanding points. Concealed elements that become accessible only during the works may require further clarification and changes to be agreed before proceeding.

Send the property's location, photographs of the rooms and a description of the points to be altered. Where available, include:

• A plan or sketch showing the existing and intended layouts.
• Sanitary fixtures and electrical equipment to be retained or replaced.
• Models already selected or purchased and their documentation.
• Details of previous work and problems observed.
• Designs, diagrams or other records of the existing installations.
• Access arrangements, occupation and other planned works.

Explain whether you need plumbing, electrical work or both. Even if you do not know the concealed routes, a clear description of the intended result helps identify missing information and prepare the assessment of your enquiry.

• Kitchen renovation

  Coordinate services with kitchen cabinetry, appliances and finishes.

• Bathroom renovation

  Define the wider renovation where the enquiry extends beyond individual services or fixtures.

• Building water supply, wastewater and rainwater drainage design

  Define design support for building pipework and drainage as a distinct scope.

• Building services design and coordination

  Define electrical design and its coordination with other disciplines.

We welcome enquiries in Lisboa, Oeiras, Cascais, Sintra, Amadora, Odivelas and Loures. Availability and the feasibility of the work are assessed for each enquiry.
