Common signs include: a persistent burning smell, especially when electrical circuits are in use; discolouration or scorch marks around sockets, switches, or the consumer unit; a circuit that trips repeatedly; visible damage to cable sheathing in accessible locations; or an EICR inspection report noting burnt or overheated wiring. If you see any of these signs, isolate the affected circuit and call us immediately.

The most common causes of burnt wiring are: overloaded circuits drawing more current than the cable was designed for; loose connections creating resistance and heat at terminals; undersized cables used for high-load circuits; sustained short circuit conditions; and external damage from building work or pest activity. In older East London properties, years of ad-hoc wiring additions can create overloaded circuits not visible at the consumer unit. We always investigate and address the root cause as part of the repair.

Yes — always. Burnt wiring indicates that a section of your electrical installation has been subjected to dangerous overheating. The damaged insulation is compromised and cannot reliably prevent arcing or fault current. Fires caused by electrical arcing inside wall and ceiling cavities can develop undetected for significant periods. We treat any report of burnt wiring as an emergency and respond 24/7 across East London.

We replace the full cable run between junction points — not just the visibly damaged section. Cable insulation that has been subjected to excessive heat may appear intact but be degraded beyond safe use beyond the visible burn area. A patch repair of burnt wiring is not considered acceptable practice and will not pass certification testing.

This depends on your specific policy and the cause of the damage. Many home insurers cover electrical damage including burnt wiring repair — particularly where the damage was caused by an insurable event. Our NICEIC certification and detailed written report documenting the damage, cause, and repair are typically required by insurers to process a claim. We provide this documentation as standard on completion.

The duration depends on the extent of the damage and the accessibility of the affected cable run. A single burned section of accessible wiring is typically repaired within 2–4 hours. More extensive damage involving multiple circuits or cables concealed in inaccessible locations will take longer. We provide a time and cost estimate after completing the initial assessment.

Yes — and urgently. Burnt wiring in a rental property or HMO is a serious safety matter with direct compliance implications. A landlord who fails to address a known fire risk from damaged wiring may face enforcement action from the local authority. We carry out emergency burnt wiring assessment and repair across all East London boroughs, issue an EIC on completion, and can simultaneously carry out an EICR if the landlord needs one for their Electrical Safety Standards obligations.

In our experience across East London, the most common causes are overloaded circuits in older Victorian and Edwardian properties (where the original wiring was not designed for modern electrical loads), loose connections at aged socket or switch back boxes, and ad-hoc extensions and additions made over decades without proper load assessment. Properties in Tower Hamlets, Hackney, and Waltham Forest frequently present this combination of factors.

Yes — burnt wiring in flats and apartment blocks requires careful handling, particularly where the affected cable runs through communal areas or shared risers. We carry out burnt wiring repairs in all types of East London residential properties, including purpose-built blocks, converted houses, and mansion blocks. Where the fault affects communal wiring, we liaise with the building management company or freeholder as required.

The most effective preventive measures are: having a full EICR carried out to identify overloaded circuits and undersized cables before they cause damage; upgrading your consumer unit to a modern 18th Edition board with RCBO protection on every circuit; avoiding the use of extension leads and multi-way adaptors as permanent solutions; and having any new electrical additions (such as EV chargers or additional sockets) properly designed and installed by a qualified electrician. We carry out all of these services across East London.

Yes — burnt wiring is treated as an emergency and we respond immediately across Newham (E6 East Ham, E7 Forest Gate, E15 Stratford, E16 Canning Town) and Hackney (E8 Dalston, E1/EC2 Shoreditch). Call 07852 280 518 at any hour and we will attend as quickly as possible. Do not delay — burnt wiring is a genuine fire risk that requires immediate professional attention.
