Commercial Electrical Services
Commercial electrical services for landlords, property managers, farms and businesses across Warwickshire, Oxfordshire, Gloucestershire and the North Cotswolds. We install, test and maintain electrical systems, leaving you with safe premises and clear compliance paperwork.
Commercial electrical work built around safety, standards and clear records
Changes to a commercial property can expose faults in older wiring, overloaded circuits or inadequate earthing. We assess the existing installation before designing alterations, taking account of tenant areas, farm buildings, plant rooms and the way each space is used.
When a landlord or property manager needs evidence for a file, our NICEIC and ECA electrical work is inspected and tested against BS 7671, including the current 18th Edition requirements. We record defects clearly, separate urgent risks from planned improvements and provide the certification needed for the next step.
Work in an occupied building needs careful coordination. Our directly employed electricians agree the scope in writing before starting, explain any isolation or access requirements and leave the work area tidy. That approach comes from a family-run electrical business serving commercial properties since 1983.
From first enquiry to completed electrical work
From the first conversation, we establish what the property needs, identify risks and agree the scope before work begins. You then receive a planned installation or maintenance visit, followed by test results, certification and practical advice on any remaining action.
Describe the property and the work
Tell us what needs changing, testing or repairing, along with any tenant, access or operational requirements. We use that information to plan the right assessment.
Assess the existing installation
Older wiring, overloaded circuits and poor earthing can affect a new installation. We inspect the relevant parts of the system and identify risks before recommending work.
Receive a clear written quotation
The quotation sets out the agreed electrical work, required materials and any access or isolation arrangements. You can approve the scope before anything starts.
Prepare the working area
Occupied premises, plant rooms and farm buildings need proper coordination. We agree where electricians will work, which areas may need isolation and how the job will affect the property.
Complete and test the work
Our directly employed electricians carry out the installation or maintenance, then test the affected circuits against BS 7671. We deal with faults found during testing before handing the system back.
Receive certification and next steps
You receive the relevant test results and electrical certification for the property file. If further improvements are advisable, we separate them from urgent defects so the next decision is clear.
Qualified work, clear records
Many of our electricians and engineers have been with Alderminster Group for more than ten years. That continuity gives commercial clients familiar technical staff, consistent records and practical knowledge of recurring faults across managed properties.
Questions about commercial electrical work
How much disruption will commercial electrical work cause?
Most commercial work can be planned around occupied areas. We agree access arrangements beforehand, isolate affected circuits safely, and explain any unavoidable disruption before engineers begin the work on site.
What happens if commercial electrical testing finds a dangerous fault?
If testing identifies a dangerous fault, we explain the risk, isolate the affected circuit where necessary, and set out the repair needed. You receive findings and certification for your records.
Can you work on older commercial electrical installations?
Older installations can still be maintained, but we first check cable condition, earthing, consumer units and any previous alterations. We then recommend only the upgrades needed for safe, compliant operation.
What paperwork will I receive after commercial electrical work?
After the visit, we provide the relevant certificates, inspection schedules and invoices, with remedial recommendations separated clearly. This gives landlords and managers an organised record for compliance files and reference.
How much does commercial electrical work cost?
Commercial cost depends on installation size, circuit complexity and remedial work identified. We inspect the premises and provide a written quotation before work starts, with scope and cost shown separately.
Commercial electrical work, properly planned and completed
When a commercial property needs electrical work, we explain the risk, recommend only the necessary action and keep the contact informed as plans change. Our NICEIC-registered electricians test their work carefully, provide the records required and finish safely and tidily.
Regional coverage that works for managed properties
We cover commercial sites across Warwickshire, Oxfordshire, Gloucestershire and the North Cotswolds, keeping arrangements with one regional electrical team.
Findings explained in plain English
An EICR or inspection report can leave several issues to weigh up. We separate urgent risks from recommended improvements, so the next step is clear.
Electrical work carried out to the right standard
Our NICEIC-registered electricians follow the required testing and installation standards. ECA membership gives commercial clients another marker of professional electrical practice.
A written quotation before work starts
You receive the proposed work and cost in writing before anything begins. If the scope changes, we explain why rather than adding surprise charges.
A properly finished site
Once the work is complete, we test the installation, remove materials and leave the premises tidy. The completed records are provided for your property files.
