How suppliers appear on this page
- Suppliers must qualify for the public Supplier Marketplace to be listed here.
- Relevance to electrical & power systems is based primarily on the capabilities a supplier has recorded.
- Where a capability match is ambiguous, it may be AI-assisted and is then administratively reviewed.
- Verification and membership badges are shown individually on each card.
- This is not an editorial ranking of the "best" companies.

Overview
Switchgear, MCCs, power distribution and electrical panels
Electrical & Power Systems covers the UK manufacturers, panel builders and installers of LV and MV switchgear, motor control centres (MCCs), power distribution, transformers, UPS systems and bespoke electrical panels - plus the contractors who install and commission them on industrial sites.
When to use
- You're specifying switchgear, MCCs or distribution boards for a new build or upgrade
- You need bespoke electrical panels designed and built to IEC or UL
- You need transformers, UPS or power conditioning for a sensitive load
- You need site-based electrical installation, commissioning or maintenance
What to look for
- Standards compliance - IEC 61439, BS 7671, IEC 60439, UL for export
- Form of separation and short-circuit ratings appropriate to your spec
- Preferred component brands (ABB, Siemens, Schneider, Eaton, etc.)
- Site capability - HV/LV qualifications, ECS, NICEIC, JIB
Buying guide
How to buy electrical & power systems
Power, control panels, switchgear and HV / LV distribution sit at the intersection of regulation, safety and very long lead times. Plan early, specify tightly.
- 01Define electrical load and growth
Capture present load, future load, harmonics, power factor and any motor starting needs before specifying the system.
- 02Choose the right standards
BS 7671, BS EN 61439 for assemblies, IEC 61850 for substation automation, ATEX where relevant. Standards drive design, not the other way round.
- 03Specify protection and selectivity
Protection grading, selectivity studies, arc-flash assessment and earthing strategy should be in the spec, not a future add-on.
- 04Plan FAT, SAT and commissioning
Factory acceptance, on-site testing, energisation procedure and witnessed commissioning are all gated, paid milestones.
- 05Lock as-built and spares
Schedules, single-line diagrams, settings sheets and a critical spares list should ship with the system, not be requested later.

Certifications required
Standards and accreditations to look for
These are the third-party certifications buyers commonly ask suppliers in this category to hold. Industrial Connected Verification is a separate check of company identity and credentials, and approved certifications uploaded by a supplier also contribute towards their Trust Score.
ISO 9001
Baseline quality system for panel builders and contractors.
IEC 61439-1/2
Standard for low-voltage switchgear and controlgear assemblies.
UL 508A
North American panel build standard for export.
BS 7671
UK wiring regulations.
NICEIC / ECS / JIB
Site personnel competence and electrical contracting approvals.
ATEX / IECEx
Hazardous area design and installation.
Typical lead times
Lead times in Electrical & Power Systems
A realistic starting point for planning. Actual lead times depend on volume, material availability, finishing, inspection requirements and current supplier load. Confirm in writing on every quote.
Panels typically 6 to 14 weeks from order, longer for switchgear with long-lead breakers. Site installation scheduled around plant shutdowns.
Supplier checklist
How to vet a electrical & power systems supplier
Run through this checklist with any candidate supplier before awarding work. If they cannot evidence an item, treat it as a risk to manage, not an assumption to ignore.
- Panel assembly certified to BS EN 61439 with type-tested designs.
- Authorised partner status for the switchgear and protection relays you specify.
- In-house test capability for HV, primary and secondary injection.
- ICP (Independent Connection Provider) or DNO approval for any grid-side work.
- Aftercare contract with response SLA for energised equipment.
- Quality system certified and audited (ISO 9001 minimum, sector standards where required).
- Two reference customers in your sector willing to take a call.
- Insurance, IP and NDA position confirmed in writing before sharing drawings or data.
- Commercial terms agreed: payment terms, currency, retention, delivery Incoterms.
Common mistakes
Common mistakes buyers make in Electrical & Power Systems
The avoidable issues we see most often, with the one-line fix that prevents them.
Treating BS EN 61439 as paperwork.
Fix: Insist on type-tested designs and verification reports, not a self-declared certificate.
Skipping arc-flash and earthing studies.
Fix: Make these mandatory deliverables in the project brief.
Ignoring DNO lead times.
Fix: Engage the DNO at week one. Connection approvals can take six to twelve months.
Underestimating commissioning windows.
Fix: Plan commissioning around plant shutdowns and book engineers well in advance.
No spares strategy.
Fix: Critical relays, contactors and breakers should be held on site, not ordered after failure.

Buyer FAQs
Buyer FAQs for Electrical & Power Systems
What standard should my panels be built to?
IEC 61439-1/2 is the default for industrial LV assemblies in the UK and EU. UL 508A applies for export to North America. State both if you ship globally.
Switchgear or MCC - what's the difference?
Switchgear distributes power between circuits and protects against faults. MCCs centralise motor starters, drives and control - useful where you have many motors in one place.
Do panel builders also install on site?
Many UK panel builders offer site installation and commissioning, especially for full MCCs. For larger projects, a separate electrical contractor often handles installation.
