Before you order the shelf

Start with what the shelf must hold

A shelf for a few photographs and a shelf for a row of heavy books create different questions. Describe the intended use, the approximate size of the items and whether that use may change. The goal is to agree a practical arrangement before choosing a product simply because it fits the width.

Think about the space around the shelf as well. A door should still open, a person should be able to pass comfortably, and everyday items should remain easy to reach. A sketch can help explain the arrangement without turning your idea into a technical installation plan.

Measure the available space

Record the width, height and depth you can safely measure from floor level. Include skirting, nearby switches, sockets, doors and windows in the description. State when a measurement is approximate, especially where a wall or alcove does not appear square.

Keep the room photograph and measurements together. A small difference can affect the position of brackets or the clearance above a desk. Ask which dimensions need to be checked on site before ordering a cut-to-size item or accepting a final layout.

Let the wall condition guide the conversation

The visible wall finish does not establish the structure behind it. Share what you know about the building and any relevant previous work, but leave the assessment of suitable fixing methods to the person accepting the installation. Do not drill exploratory holes or remove finishes to prepare an inquiry.

Tell the provider about known restrictions, concealed-service information supplied by the building owner, or areas that must not be altered. If the wall condition cannot be assessed confidently, an inspection or a different installation approach may be needed.

Check the product before purchasing

Send the product dimensions, assembly information and intended load information if available. Confirm who supplies the shelf, brackets and other materials, and whether the proposed product suits the agreed location. A photograph of a similar shelf is inspiration rather than a specification.

Discuss returns and replacements before ordering special items. If a product arrives damaged, incomplete or different from its description, the appointment may need to change. Keep packaging and instructions until the installation and any agreed checks have been completed.

Agree the finish and handover

Confirm the visible position, any finishing work and how the area should be left. Ask whether decoration or making good is included in the scope. These details are easier to agree before work starts than after a bracket has been positioned.

At handover, retain the product instructions and any care or use notes provided for the agreed installation. Clarify outstanding questions before loading the shelf. Changes to the intended use or weight should be discussed rather than assumed to be covered by the original arrangement.
