As a commercial electrician, we regularly undertake projects in a variety of office spaces. Whether we’re converting an office into an HMO or creating state-of-the-art wiring designs that include data cabling, lighting, power and alarm systems, the designs we produce are fundamental to the success of the whole project. Therefore, in this post, we thought that we’d share with you our general design process, so you can see how much effort and dedication goes into each one.


The Basics Of Electrical Design

Before the electrical design process can begin, we need to ensure that what has been requested will work within the architect’s, builder’s or owner’s building plans. These plans detail the information the local inspection authority needs to know to approve the plans, as well as specific electrical designs and documentation that ensures that these designs will adhere to required building regulations. We will determine whether the electrical designs are feasible, suggest how they can be improved and then send the plans back to the owner to send to the local authority.




The Design Process:

Step 1: Project Scope.

The scope of the design depends on what the office requires. For example, if it requires a brand-new electrical system, then we will determine how best to incorporate all new electrical wiring into this system. At this stage, we also ensure new systems can cope with additional loads that will be expected of them.




Step 2: The Electrical Plan.

A design plan will include various parts:

  1. General electrical requirements, such as receptacle outlets found throughout the office, used for computers.
  2. Specialised electrical requirements, for equipment that may need separate electrical circuitry, such as microwaves and vending machines.
  3. Lighting systems, including fixtures and their controls.
  4. Electrical distribution systems, such as the switchboard.




Step 3: Ensuring Industry Standards Are Met.

When each part of the design plan has been determined, we then design each part to industry standards to ensure safety and function. These standards include the BS 7671:2018, which refers to electrical installations, including protection for electric shocks, voltage disturbances and thermal effects.




Step 4: Bringing The Electrical Plan To Life.

With steps 1-3 complete, we then create the plan using blueprints or a CAD (computer-aided design) tool, which allows us to visualise the office’s electrical circuits. Each device is referenced by various symbols to ensure everyone involved understands the plan. We then present our plan to the architect or builder, who as mentioned above, will pass it on to the local authority.
