Trusted relationships built through real work.
For more than two decades, our team has worked with property businesses, commercial organisations, institutions and recognised building-services brands across London.
Selected examples from our commercial experience across property, building services, institutions and commercial environments in London.
You do not need to diagnose the electrical problem before contacting us.
Electrical faults are not always obvious. Repeated tripping, intermittent failures, damaged equipment or loss of power may involve several parts of the installation before the correct response becomes clear.
Tell us what the building is doing.
Bigness helps understand the symptoms, identify the electrical systems involved and determine the appropriate technical response.
Start with the problem, not the electrical component.Loss of power or partial power failure
Repeated tripping or protective devices operating
Faulty circuits or intermittent electrical problems
Lighting failures or recurring lighting faults
Damaged switches, sockets or electrical accessories
Ageing distribution equipment or electrical components
Inspection findings requiring remedial work
Repeated repairs without a clear long-term solution
Resolve the fault. Correct the defect. Plan what comes next.
Electrical requirements range from immediate faults and loss of service to inspection findings, known remedial actions and planned system upgrades. The right response depends on the condition, risk and operational importance of the installation.
Investigate and stabilise the immediate fault.
Reactive electrical work starts with the reported problem — identifying the affected circuit or equipment, making the situation safe where required and establishing what repair or further investigation is needed.
Correct the identified electrical defect.
Remedial work follows a diagnosed fault, inspection finding or testing result and focuses on completing the corrective work required to address the identified issue.
Upgrade before ageing systems become repeated problems.
Where distribution equipment, circuits, lighting or other electrical components are ageing or increasingly unreliable, planned work can improve condition and future reliability.
The question is not only how to restore the affected electrical system today, but whether repeated repair remains the right long-term response for the building.
Reliable electrical systems depend on more than fixing individual faults.
Electrical installations can remain operational while becoming increasingly difficult to maintain, repeatedly faulting or no longer suited to the demands placed on the building.
Where appropriate, Bigness looks beyond the immediate issue to understand the wider electrical system and what may need attention next.
Distribution
Review distribution arrangements and equipment where faults, ageing components or system changes are affecting reliability.
Circuit Condition
Investigate recurring circuit faults, damage or deterioration where repeated repair is becoming a regular requirement.
Protective Devices
Consider protective devices and associated equipment where repeated tripping or electrical faults indicate a wider issue.
Loading & Suitability
Review whether the existing installation remains appropriate for current building use, equipment and operational demand.
Lighting Performance
Identify recurring failures, poor coverage or ageing lighting systems where repair or planned improvement may be required.
Controls & Interfaces
Consider how electrical systems interact with heating, HVAC, controls, plant and wider building services.
Maintenance Access
Identify arrangements that make future inspection, isolation, servicing or repair unnecessarily difficult.
Ageing Components
Review equipment that is increasingly unreliable, obsolete or difficult to maintain because of parts availability.
Future Adaptability
Consider whether today’s repair or upgrade supports future maintenance, refurbishment and building-system changes.
Understand the system before deciding whether to repair, remediate or upgrade.
An isolated fault may require a simple repair. Repeated faults, ageing equipment or unsuitable distribution may indicate that a wider electrical improvement is the better long-term response.
Inspection only creates value when the resulting actions are controlled.
Electrical inspection and testing can identify defects, deterioration and actions requiring further attention. The next challenge is making sure those findings are understood, scoped, completed and properly recorded.
Inspect
Arrange the appropriate electrical inspection or testing through a competent electrical specialist.
Identify
Review the reported observations, defects and recommendations arising from the inspection.
Scope
Translate identified issues into a clear remedial scope and determine the appropriate technical response.
Remediate
Coordinate and complete the agreed corrective electrical works through the appropriate competent resource.
Retest
Arrange follow-up testing or verification where required by the work or inspecting specialist.
Record
Keep relevant reports, completion evidence and remaining electrical actions organised.
From periodic inspection to corrective electrical work.
The report is an input. Closing the actions is the operational work.
Bigness can help coordinate inspection requirements, organise access, track resulting actions, define remedial scopes and coordinate approved corrective works.
Formal electrical inspection, testing, certification and technical sign-off remain with the appropriately competent electrical person responsible for that work.
Explore Building Compliance →An electrical report should not disappear into a folder. Identified actions should have a scope, an owner, a completion route and the evidence needed to close them.
Upgrade electrical systems when repair is no longer the best long-term decision.
Electrical systems can remain operational while becoming increasingly difficult to maintain, less suited to current building use or more exposed to recurring faults and ageing components.
Bigness can help define and coordinate planned electrical improvements where replacement or wider system upgrade is more appropriate than continued isolated repair.
Repeated electrical problems can be a signal that the system needs more than another repair.
A local repair may still be the correct response where the installation remains serviceable and the defect is isolated.
Where equipment is ageing, recurring defects remain open or the installation no longer supports the building effectively, a planned upgrade may provide better reliability and lifecycle value.
The objective is the appropriate intervention at the appropriate time.Distribution Board Upgrades
Replacement or improvement of ageing distribution equipment where condition, suitability or future requirements justify it.
Circuit Upgrades
Alteration or improvement of circuits where the existing arrangement no longer supports current building needs.
Lighting Upgrades
Planned replacement and improvement of internal, external and common-area lighting systems.
Controls & System Interfaces
Electrical upgrades associated with controls, HVAC, heating plant and other building-service interfaces.
Rewiring Where Required
Planned rewiring or circuit replacement where condition, alteration or wider refurbishment creates a justified need.
Electrical Work Within Refurbishment
Electrical alterations coordinated alongside refurbishment, layout changes and wider building improvement works.
Electrical improvement can involve more than replacing one failed component.
Electrical upgrades can form part of a wider refurbishment, building-system replacement programme or planned capital improvement.
One technical capability supporting four building outcomes.
Electrical is one part of the wider Bigness delivery model. The same technical capability can support compliance actions, day-to-day maintenance, building improvements and managed building operations.
Building Compliance
Electrical inspection, testing and remedial actions arising from compliance requirements, specialist reports or identified defects.
Building Maintenance
Fault investigation, electrical repairs, lighting maintenance and planned attention to building electrical systems.
Building Improvements
Distribution upgrades, lighting improvements, system alterations, rewiring and electrical work within wider refurbishment programmes.
Managed Building Operations
Electrical inspections, open defects, remedial actions, specialist contractors and future upgrades coordinated within the wider building programme.
Electrical is part of the delivery engine — not the whole proposition.
Bigness uses the technical capability required by the building while the wider objective remains the same: keeping the building safe, reliable and efficient.
The right electrical competence for the right task.
Electrical work can range from straightforward maintenance to formal inspection, testing, regulated work, specialist design and technical certification.
The competence required should match the nature, complexity and responsibility of the work being undertaken.
Coordinate and deliver within the agreed scope and competence.
Bigness can help understand the requirement, define the scope, organise the appropriate technical resource and coordinate electrical work within our agreed appointment.
Where the work requires formal inspection, testing, specialist design, certification or technical sign-off, that responsibility remains with the appropriately competent electrical professional.
Coordination does not replace specialist competence or professional responsibility.Appropriate Competence
The electrician or specialist carrying out the work should have the competence appropriate to the installation, task and level of responsibility involved.
Inspection & Testing
Formal electrical inspection and testing should be undertaken by an appropriately competent electrical person responsible for the technical assessment.
Specialist Electrical Work
Complex systems, controls, plant interfaces or specialist installations may require additional technical expertise beyond general electrical maintenance.
Certification & Sign-Off
Electrical certification, professional opinions and formal technical sign-off remain with the competent person responsible for that work.
One electrical requirement may involve several technical disciplines.
Bigness can coordinate electrical specialists alongside heating, HVAC, controls, fire systems and other building services where the work forms part of a wider building requirement.
Bigness coordinates the process. Specialist inspection, certification and technical sign-off remain with the appropriately competent party.
A clearer route through electrical work.
Electrical work should move through a clear process — from understanding the reported problem and investigating the installation to defining the scope, coordinating competent delivery and recording the completed outcome.
Understand the Issue
Start with the reported fault, affected areas, installation history and available building information.
Investigate
Review the relevant circuits, equipment or electrical system to establish the likely cause and any immediate requirements.
Define the Scope
Establish whether the next step is repair, remedial work, testing, alteration or planned upgrade.
Coordinate the Right Specialist
Bring in the appropriate competent electrician or specialist required for the identified work.
Deliver the Work
Complete the agreed repair, remedial action, electrical alteration or planned system improvement.
Verify & Record
Confirm the agreed outcome, collect relevant evidence and record any remaining actions or future priorities.
Understand what is happening. Coordinate the right response. Record the outcome.
This keeps electrical work connected to the wider building rather than treating every fault, report or remedial action as an isolated job.
Electrical work in practice.
