Electrical Installation, Testing and Repair Services
Electrical Installations and New Circuits
We install electrical systems and new circuits to support your business requirements, whether you are adapting an existing workspace or planning a refurbishment. Sharing your layouts, equipment specifications and anticipated power requirements helps us assess the proposed installation. The scope can then be discussed alongside site access and coordination with other trades.
Lighting Upgrades
We upgrade lighting to suit the way your premises are used, taking account of existing fittings, working areas and the improvements you want to achieve. The proposed work can address changing layouts or lighting that no longer meets your operational needs. Installation arrangements are discussed around access and business hours to limit avoidable disruption.
Electrical Infrastructure Upgrades
We undertake work to modernise electrical infrastructure where existing installations need to accommodate changes to the premises. Our assessment considers the current system, proposed equipment and requirements of the project. This helps establish an appropriate scope and identify any further investigation needed before work proceeds.
Electrical Fault Finding and Diagnostics
We investigate electrical faults to identify their source and understand how they affect your premises. Details of when the problem occurs, which equipment is affected and any previous repairs can help guide the investigation. Our findings inform the recommended repair or any further testing required.
Electrical Repairs
We carry out repairs to address identified electrical defects and restore the operation of affected installations. The work is determined by the fault, equipment condition and findings of any inspection or testing. We discuss access requirements and any necessary interruption to the supply so your team can plan accordingly.
Electrical Inspection and Testing
Our electrical inspection and testing services help establish the condition of installations and identify issues requiring attention. The scope is agreed around your premises, the purpose of the inspection and any available previous reports. Reporting and certification requirements should be confirmed when booking so the documentation matches the work undertaken.
Planned Preventative Electrical Maintenance
Our maintenance programmes include scheduled electrical testing and system checks to help identify developing faults and organise follow-up work. Visits are planned around the installed equipment, building operations and access requirements. Agreed reporting provides facilities teams with a record of completed tasks and recommendations, supporting maintenance planning and budgeting.

Planned Maintenance and 24/7 Reactive Support
Reactive electrical work addresses an existing fault, while planned maintenance follows a schedule of checks and servicing. A reactive visit may be needed when equipment stops working or an electrical issue disrupts the premises. Planned maintenance helps facilities teams organise access, identify developing problems and manage future expenditure.
PHD Mechanical offers round-the-clock support alongside its planned maintenance services. When reporting an urgent problem, provide the property address, a description of the fault and details of its impact on the building. Our team can confirm availability and discuss the next steps; attendance and repair times depend on the circumstances. Maintenance agreements can include reporting and relevant certification for the systems covered. Agreeing these requirements at the outset gives your team a clearer record of completed work and outstanding actions.
Electrical Support for Commercial and Managed Properties
Our wider building services experience includes commercial offices, healthcare facilities, residential developments and industrial premises. For electrical enquiries, we assess the proposed work and site requirements individually, including the need to coordinate access within occupied buildings. We welcome enquiries from contractors and facilities teams managing:
- Offices and retail: electrical installations, lighting and maintenance around business hours.
- Healthcare premises: carefully coordinated access and identification of essential services.
- Hospitality and restaurants: work planned around guests, customers and operating schedules.
- Industrial buildings and warehouses: electrical requirements across working areas and associated facilities.
- Residential blocks and mixed-use developments: coordination across shared areas and occupied properties.
- Construction and refurbishment projects: electrical work aligned with other trades and programme dates.
Frequently Asked Questions
Can contractors arrange electrical work for refurbishment projects?
Contact PHD Mechanical with your drawings, specification, programme dates and access requirements. Include details of any occupied areas and equipment that must remain operational. This allows the proposed work, coordination with other trades and any necessary interruptions to be discussed before the scope and delivery arrangements are agreed.
What electrical credentials and documentation can contractors request?
PHD Mechanical’s electrical services page identifies the company as a NAPIT-approved contractor. Before appointment, contractors can request current registration details and confirmation that the proposed work falls within the relevant scope. Any required inspection records, completion certificates and handover information should also be agreed at quotation stage.
Can facilities managers include electrical checks in a maintenance agreement?
Yes. Our planned preventative maintenance services include electrical testing and system checks. Provide your equipment information, previous reports and operating hours so the required tasks and visit arrangements can be discussed. The agreement should identify the systems covered, reporting requirements and responsibilities for following up on any defects.
Can electrical maintenance be arranged around building operations?
Access requirements and operating hours should be discussed when planning the work. Facilities managers should identify essential equipment, occupied areas and any restrictions on power interruptions. This helps establish suitable visit arrangements and whether work needs to be phased. Any necessary shutdowns should be confirmed in advance so affected building users can be informed.
What areas do you cover, and how can I confirm costs and availability?
PHD Mechanical serves London and the South East, with offices in Harrow and Central London. Contact the team with your postcode, a description of the work and its urgency. We can discuss availability and whether an initial assessment is needed before quoting. Ask for applicable charges and exclusions to be clarified before authorising the work.
