Q: Are your electricians certified?

BS 7671:2018 (18th Edition) – The latest edition of the Wiring Regulations, ensuring our electricians follow the most current safety standards and practices for electrical installations.

City & Guilds 2394 (Initial Verification and Certification of Electrical Installations) – This qualification allows our electricians to thoroughly inspect and verify new electrical installations, ensuring they are compliant and safe from the start.

City & Guilds 2395 (Periodic Inspection, Testing, and Certification) – This certification covers the inspection and testing of existing installations to ensure they remain safe and compliant, crucial for Electrical Installation Condition Reports (EICRs).

Q: How quickly can you respond to an emergency call-out?

Q: Do you offer free quotes for your services?

Free Quotations

A: Yes, we offer free, no-obligation quotes for all our electrical services. Simply get in touch, and we’ll arrange a consultation.

Q: What is an EICR, and do I need one?

Electrical Safety Reports (EICR)

A: An EICR (Electrical Installation Condition Report) is a formal report that assesses the condition and safety of an electrical installation. While it does not require the system to meet the very latest wiring regulations (BS 7671:2018), it identifies any non-compliance with the current standards and categorizes them accordingly. For example, if the system was installed under an earlier edition of the regulations, non-compliance may be classified as a C3 (indicating improvement is recommended but not required for safety).

EICRs are required by law for landlords in rental properties and must be carried out at least every 5 years to ensure tenant safety. For homeowners, an EICR is recommended every 5-10 years, or before buying or selling a property, to maintain safety and compliance.

Periodic inspections conducted during the EICR include:
      • Checking the condition of wiring, sockets, switches, and light fittings.
      • Testing earthing and bonding to confirm safe fault current diversion.
      • Inspecting fuse boards, consumer units, and protective devices to ensure they are functioning correctly.
      • Verifying the performance of Residual Current Devices (RCDs) and other safety measures.
      • Identifying potential fire or shock hazards, circuit overloading, and other risks.
      • Any issues found during the inspection are categorized based on their severity, from C1 (immediate danger) to C3 (improvement recommended but not immediately necessary). This ensures transparency about the safety of your installation, even if it was installed under a previous version of the regulations.
Q: Can you help with smart home installations?

Smart Home Solutions

A: Absolutely! We specialize in both simple and advanced smart home systems, including lighting controls, heating systems, security systems, and more.

Q: Do you offer maintenance contracts for commercial properties?

Commercial Services

A: Yes, we provide tailored maintenance contracts for businesses, ensuring your electrical systems are always safe and fully operational.

Q: How do I know if I need an upgrade to my consumer unit (fuse box)?

Consumer Unit Upgrades

A: If your fuse box is outdated, frequently trips, or if you're adding more electrical appliances to your property, it may be time for an upgrade. Frequent tripping is often a sign of a faulty circuit, though it could also be due to a failing MCB (Miniature Circuit Breaker). In any case, it’s important to have a professional assess the issue to determine whether an upgrade is needed for safety and reliability.

Modern consumer units (fuse boxes) offer several advantages over older systems, including:

  • RCD Protection (Residual Current Device) – Protects against electrical shocks by quickly disconnecting the circuit if it detects an imbalance, ensuring your home or business is safe from potential harm.

  • Surge Protection – Shields your electrical appliances from voltage spikes, protecting sensitive devices like computers, televisions, and other valuable electronics from damage caused by power surges.

  • Fire-Rated Consumer Units – Modern units are built with fire-resistant materials to contain any electrical fire within the box, offering an additional layer of safety for your property.

Upgrading to a modern consumer unit enhances both safety and compliance with current regulations, ensuring that your electrical system is more reliable and better equipped to handle today’s energy demands.

Q: Can you install electric vehicle (EV) charging points?

EV Charging Points

A: Yes, we offer installation of EV charging points for both residential and commercial properties. We can help you choose the right charger and provide a seamless installation service.

Q: What types of security systems do you install?

Security Systems

A: We install a range of security systems, including CCTV, alarm systems, and secure entry systems like maglocks and pin-entry systems for both homes and businesses.

Q: How long does it take to complete a full house rewire?

Rewiring Projects

A: The time frame depends on the size of your property and the complexity of the work. Typically, a full house rewire can take from 10 days. We’ll provide a more accurate estimate after assessing your property.

Q: Can you install outdoor lighting and power points?

Outdoor Electrical Work

A: Yes, we provide installation of outdoor lighting and external power points, perfect for garden lighting, outdoor kitchens, and more.

Q: How can I reduce my energy bills with your services?

Energy Efficiency

A: We offer energy-efficient solutions like LED lighting upgrades, smart heating controls, and modern electrical systems that can help you save on your energy bills.

Q: Do you handle electrical inspections for landlords?

Landlord Services

A: Yes, we offer comprehensive electrical inspections and EICR reports to ensure your rental properties meet legal safety requirements.

Q: What payment methods do you accept?

Payment Options

A: We accept a range of payment methods, including cash, bank transfers, credit/debit cards, and online payments through our secure portal.
