What gets confirmed before accessory work is booked

Before booking sockets, switches, spurs or similar points, we check the point count, product choices, useful records and whether any inspection or testing should come first.

An Electrical Installation Certificate is called an EIC. An Electrical Installation Condition Report is called an EICR. If you have a recent EICR, Electrical Installation Certificate or certificate from earlier work, send every relevant page, including the circuit details and test results. An EIC records the work named on it. An EICR reports on the condition of the existing installation within the areas and limits stated. A straightforward like-for-like accessory replacement does not automatically need a whole-home EICR. For larger changes, several affected points or an installation with an unclear history, targeted inspection and testing may be sensible before a firm plan and price are agreed. Sometimes an EICR is the better starting point. Finding concerns early reduces the chance of an unexpected change after work has started. Where a separate inspection or testing visit is recommended, we explain the charge before you decide whether to book it.

What we check before a firm plan

  • The number and type of points, the rooms, the planned products and whether the work is like-for-like replacement or a larger change.
  • Whether the chosen accessories suit the existing points, boxes and intended use.
  • Whether the relevant circuit, protective device, earthing or bonding needs checking for the proposed work before installation starts.
  • Missing or incomplete records do not by themselves mean the installation is unsafe or that a full EICR is needed.

What to send if you have it

  • Every page of a relevant certificate or report, including its description, circuit schedule, test results, extent and limitations.
  • The point count, room list and any product links or exact model numbers already chosen.
  • A safe exterior photo is optional. Keep the plate in place; if you have no records, simply say so.
