Electrical design turns a set of architectural drawings into an installation that works: the right supply, distribution that suits the building, circuits sized for their loads, and accessories and lighting where people will actually use them.

What electrical design covers

  • Supply and capacity. Assessing maximum demand, including heat pumps, EV charging, cooking, showers and solar, and confirming the supply can carry it.
  • Distribution. Where the main board and any sub-boards sit, and how circuits are divided so a single fault has limited effect.
  • Circuit design. Protective devices, cable sizes and routes, voltage drop and disconnection times to BS 7671.
  • Layouts. Socket, switch, lighting and data positions drawn against furniture and joinery, not left to the day.
  • Interfaces. Supplies and containment for heating, ventilation, security, AV, lighting control and data.

Working with the design team

Electrical decisions affect structure (notching joists, routes through steelwork), joinery (lighting in cabinetry), finishes (accessory plates, recessed fittings) and other services. We work alongside architects, structural engineers, M&E consultants, lighting designers and AV integrators, including the Inspire group’s own Inspire Audio Visual, so these interfaces are resolved on paper.

From design to installation

A design gives you an accurate quotation, a clear scope for the build programme, and a record of what was intended. If we design it, we can install it; if another contractor installs it, the design still gives them a clear brief.

FAQs

Electrical design: questions

Do we need an electrical design for a house?

For a straightforward extension, a marked-up plan agreed with the electrician is often enough. For a new build, a large renovation or anything with lighting control, heat pumps, EV charging or solar, a proper design avoids under-sized supplies and costly changes on site.

Can you work from an architect's or M&E consultant's design?

Yes. We install to third-party designs and will raise any practical or regulatory concerns before work starts.

Will the design consider future loads like heat pumps and EV chargers?

Yes. Supply capacity and spare ways for likely future loads are part of the design conversation, because increasing a supply later is slow and expensive.
