Common Electrical Problems and Warning Signs

Our local electricians regularly attend properties for circuits or fuse boards that keep tripping, sockets or lights that have stopped working, flickering or buzzing lights, burning smells or scorch marks, loss of power to part or all of a building, old or damaged wiring, appliances that trip the electrics, RCDs that won’t reset, loose sockets and accessories, water-damaged electrical equipment, overloaded circuits, and incorrect DIY alterations.

During inspections and repair visits, the underlying causes we most often find include loose neutral or live connections, burnt cable terminations, high earth fault loop impedance, poor insulation resistance, incorrect cable sizing, missing or inadequate RCD protection, reverse polarity, water ingress, exposed live parts, poor-quality DIY alterations, ageing consumer units, and inadequate earthing or bonding.

If you notice any of these signs, even if the problem seems minor, it can indicate a loose connection, overloaded circuit or deterioration elsewhere in the installation, and is worth having properly assessed rather than left. We diagnose the underlying cause rather than simply resetting the breaker and leaving the fault unresolved.

Consumer Unit Replacement

The consumer unit distributes electricity throughout the property and protects against electrical faults. A replacement may be recommended where the existing board has a damaged enclosure, outdated protective devices, no RCD or surge protection, signs of overheating, or is overcrowded, poorly labelled or unsuitable for planned additional circuits.

Electrical Safety Testing and EICR Services

An Electrical Installation Condition Report assesses the condition of a property’s fixed wiring — consumer units and distribution boards, protective devices, earthing and bonding, wiring condition, socket and lighting circuits, polarity, RCD operation, signs of overheating, past alterations, and the accessibility of live parts. EICRs are commonly arranged by landlords, homebuyers, homeowners, letting agents, property managers, employers, commercial property owners and HMO operators.

Electrical Maintenance for Commercial Properties

Planned electrical maintenance reduces unexpected failures, improves safety and supports compliance across offices, shops, restaurants, hotels, schools, warehouses, industrial premises, care homes, apartment blocks, HMOs and mixed-use buildings. A typical maintenance programme includes periodic inspections, distribution board checks, lighting repairs, emergency lighting tests, socket and accessory checks, fault investigation, PAT testing, remedial work and maintenance records.

Brands and Equipment We Work With

Our electricians work with products and equipment from recognised electrical manufacturers, subject to suitability, availability and the specific requirements of each installation. Common brands include Hager, Schneider Electric, MK Electric, Crabtree, BG Electrical, Click Scolmore, Lewden, Wylex, FuseBox, Eaton, Aico, Hispec, ESP and Honeywell. We assess every installation based on its condition, safety and compatibility, and we do not recommend replacing properly functioning equipment simply because it was installed by another contractor or manufactured by a different brand.
