FAQs – Electrical Design & Consultancy

Q: How is consultancy different from standard electrical work?


Consultants plan the system before work starts – creating the drawings and calculations that guide the install. This means fewer errors on-site, faster delivery, and full compliance from day one.

Yes. All designs follow BS 7671 (18th Edition Wiring Regs), plus Part L (energy use), and BS 5266 for emergency lighting if needed.

You’ll receive a full technical pack with:

  • CAD/PDF layout drawings for power, lighting, comms, etc.
  • Cable containment routes
  • Load calculations and distribution board schedules
  • Emergency lighting and data layouts
  • As-built drawings (if we support during install)

Yes. We always carry out a site survey to check conditions, measure up, and make sure the design matches the real space.

Absolutely. We provide clear documents that help contractors quote accurately – reducing surprises and keeping projects on budget.

We handle both. Whether you’re redesigning a full building or just adding to an existing system, we tailor the design to your scope.

Yes – we hold both professional indemnity and public liability insurance.
