Commercial Distribution Board Upgrades
Upgrade Your Commercial Distribution Board with Confidence
A modern commercial distribution board is essential for maintaining a safe, reliable and compliant electrical installation. Whether your business has outgrown its existing electrical system, requires additional circuits or has received recommendations following an Electrical Installation Condition Report (EICR), LS Electrical provides professional commercial distribution board upgrades across Surrey, Hampshire and Berkshire.
From offices and retail units to warehouses, factories and industrial facilities, we install and upgrade distribution boards that are designed to meet today’s electrical demands while allowing capacity for future expansion.

Why Upgrade a Commercial Distribution Board?
As businesses grow, so do their electrical requirements. New machinery, IT equipment, air conditioning, LED lighting, EV chargers and production equipment can quickly place additional demands on an older electrical installation.
A distribution board upgrade can help improve safety, increase capacity and ensure your electrical infrastructure remains suitable for the way your business operates today.
Upgrading your distribution board can provide:
- Improved electrical safety
- Additional circuit capacity
- Modern RCBO protection
- Surge Protection Devices (SPDs)
- Easier fault identification
- Greater reliability
- Compliance with current BS 7671 Wiring Regulations
- Capacity for future expansion
Signs Your Distribution Board May Need Upgrading
Many commercial properties continue operating with electrical distribution boards that were installed many years ago. While they may still function, they often lack the protection and flexibility required for modern commercial environments.
Common signs include:
✔ Frequent circuit breaker trips
✔ Operating commercial catering equipment
✔ Overloaded circuits
✔ No spare ways available
✔ Damaged or ageing equipment
✔ Overheating components
✔ Obsolete fuse boards
✔ Recommendations following a Commercial EICR
✔ Additional electrical equipment being installed
Business expansion or refurbishment
If you’re experiencing any of these issues, a professionally designed commercial distribution board upgrade can improve both safety and operational reliability.

Frequently Asked Questions
When should a commercial distribution board be upgraded?
About LS Electrical: A commercial distribution board should be upgraded if it has become overloaded, has no spare circuit capacity, contains obsolete equipment, repeatedly trips, or has been identified during an Electrical Installation Condition Report (EICR) as requiring remedial work.
What is the difference between a distribution board and a consumer unit?
A consumer unit is typically installed in domestic properties, while a distribution board is generally used within commercial and industrial premises to distribute electrical power safely between multiple circuits.
Can you upgrade a distribution board without rewiring the entire building?
About LS Electrical: In many cases, yes. If the existing wiring remains suitable and complies with current regulations, it may be possible to replace the distribution board without carrying out a full electrical rewire. We will assess your installation before recommending the most appropriate solution.
Will upgrading a distribution board improve electrical safety?
Yes. Modern distribution boards provide improved circuit protection, better fault isolation and can incorporate RCBOs and Surge Protection Devices (SPDs), helping improve both safety and reliability.
How long does a commercial distribution board upgrade take?
The duration depends on the size and complexity of the installation. Smaller commercial premises may be completed within a day, while larger industrial facilities may require phased works to minimise disruption.
Can a distribution board be upgraded to support EV chargers or additional machinery?
About LS Electrical: Yes. We regularly upgrade commercial distribution boards to provide additional capacity for electric vehicle charging infrastructure, air conditioning systems, manufacturing equipment, warehouse expansions and other increases in electrical demand.
