What Is Electrical Remedial Work?

Electrical Remedial Works London are carried out by qualified electricians to rectify (repair) any safety issues or defects with the electrical installation of either a residential or commercial property.

The safety issues (defects) often come to light after an Electrical Installation Condition Report (EICR) has been carried out, so sometimes the remedials are described as EICR remedial works. London landlords and property managers regularly require electrical remedial works and testing to keep their installations compliant and safe.

    It's always perplexing to find services online and pick the right one, regardless of reviews. I can vouch for Hexo, who was professional and timely from the day of my first enquiry, very patient and helpful working around my difficult schedule. They had a long and difficult task to do with a 3 phase board, managed to have all the spare parts with them, and their team executed in a timely way, with patience and kindness. I definitely recommend them!

    Why Are Electrical Remedial Works Important?

    Electrical remedial works are undertaken to enable a Satisfactory (safe) electrical status for the property so that the owner is legally compliant with current regulations and the electrical system in the property is safe for its intended use. Regular testing and inspections allow faults and defects to be identified early before they become dangerous.

    We can undertake residential and commercial electrical remedial work across London and the South East following one of our EICRs or complete a list of required repairs and remedial actions from another company’s EICR.

    Electrical Remedial Repairs Following an EICR

    If you choose Hexo Electrical Testing to complete your electrical remedial repairs following our EICR, the remedial work will be carried out by one of our skilled engineers, and on completion, we will issue you with an Electrical Installation Certificate or Minor Works Certificate and a Satisfactory EICR.

    If the works fall under Part P of the building regulations, then we will also issue you with a Part P Certificate for your compliance purposes.

    Which Defects Need to Be Rectified?

    You can choose whether to rectify only the minimum defects required to achieve a Satisfactory EICR status, which is all C1/C2/FI defects. Or, you can choose to make the installation fully compliant with the latest electrical regulations by having us complete the C3 recommendations as well.

    When Do I Need  Electrical Remedial Work Done?

    You should have electrical remedial work completed as soon as possible after it has been identified as being required. It is usual for the requirement to be identified after an EICR has been conducted.

    For Rental Properties

    It is a legal requirement for landlords that remedial work be completed within 28 days to make the electrical installation Satisfactory.

    For Commercial Premises

    Remedial work should be completed as soon as possible to make the electrical installation safe and to help comply with the Electricity at Work Regulations 1989, which are legal statute.

    For Owner Occupied Residential Properties

    It is advisable to have the remedial work completed as soon as possible for your own safety and that of others in your building. Electrical safety should be a priority.

    Residential Electrical Remedial  Work

    When the electrical installation in the home you own or manage is well-maintained, there is a significant reduction in the safety risk to the building itself and the individuals who live there.

    For landlords using our services, you can prove that your properties have the very best electrical compliance from a safety point of view; this will give you and your tenants peace of mind that your offering is superior to others on the market.

    We can carry out an EICR on any residential property in London or Greater London and see if any remedial work is required. If it is, then we will send you an itemised quotation for the remedial work.

    Our skilled engineers will carry out your remedial work, and we will issue you all the required certifications to be legally compliant.

    Commercial Electrical Remedial Works

    Rented properties Landlords Prices

    Commercial electrical remedial works are essential to safely maintaining your fixed electrical installation. There is a duty of care required from business owners to ensure their workforce and any guests are always kept safe whilst on the premises. Providing a compliant electrical installation is an integral part of this duty.

    Why are commercial electrical repair works important?

    Inferior, damaged, or poorly maintained electrical systems are one of the main causes of fires in the workplace. Furthermore, power loss can occur because of poorly maintained electrical installations, leading to business setbacks and overrun costs.

    How Is Electrical Remedial  Work Conducted?

    So, how is remedial electrical work completed? Well, depending on the severity of the issues identified during your Electrical Installation Condition Report (EICR certificate), certain defects will be given priority. Our engineer will work on each defect and rectify it to a satisfactory condition as outlined on our quotation. 

    What Are the EICR Defect Codes?

    Ranging in severity, there are four observation codes. To achieve compliance, you will need to carry out remedial repairs on any C1, C2 and FI faults immediately. However, rectifying C3 recommendations as well is best practice

    Code C1

    This is the most severe observation code. It means danger is present and there is an immediate threat to electrical safety. Action is mandatory and you will be issued with a “Electrical Danger Notice” and advised on how we can repair the defect to a satisfactory state, usually we will carry out this repair during the inspection visit.

    Any number of C1 defects make the EICR an Unsatisfactory Status.

    Code C2

    C2 means there is a potentially dangerous defect with your electrical system and urgent corrective work is required. The issue is usually not an immediate concern, but it is likely to become dangerous to property or life if a fault with the electrical installation occurs.

    Any number of C2 defects make the EICR an Unsatisfactory Status.

    Code C3

    Code 3 is a lower-level code defined as ‘Improvement Recommended’. This means a non-regulatory issue has been identified, or an element of the installation is recommended to be improved.

    There is no immediate danger, and an EICR can have a satisfactory outcome if there are only C3 codes reported on it.

    Code FI

    The FI observation code highlights that further investigation into a part of the electrical installation is required. This means our inspector has found something that needs to be looked at in more depth.

    You will be given an Unsatisfactory EICR until the inspector can confirm if the installation is safe.

    For a clearer understanding of the different EICR Defect Codes and their implications, refer to the table below.

     Code  Severity Level  Description
     C1  Most Severe  Immediate threat to electrical safety. Immediate action required.
     C2  Potentially Dangerous  Urgent corrective work required.
     C3  Improvement Recommended  Non-regulatory issue identified.
     FI  Further Investigation  Part of the electrical installation needs to be looked at in more depth.





    What Are Some Common Issues That Require Remedial Electrical Work?

    No matter what issues are identified, we will undertake quick and efficient remedial work to render your system compliant with BS 7671, the national standard for electrical installations.

    Once remedial works have been satisfactorily carried out, we will issue you with certification for the remedial works themselves and a Satisfactory EICR.

    Here are some common defects that require electrical remedial work, categorised under the coded observations:


    Examples of C1 Electrical Defects

    If you’re looking for examples of C1 electrical defects that require electrical remedial repairs, then this might be helpful.

    An example of a C1 defect is accessible live conductors due to damage or deterioration or due to removed maintenance panels that should be fitted to enclose the live conductors. This defect presents an immediate risk of electric shock and, as such, a risk to life.

    An overheating loose cable termination in a distribution board could be considered a C1 defect as it represents a serious fire risk and, as such, is a risk to property and life.

    Both examples are considered very serious and pose an immediate danger and should be rectified immediately.

    Examples of C2 Electrical Defects

    As for examples of C2 electrical defects, this could be anything from incorrectly sized earthing and bonding conductors to your RCD not tripping correctly when tested.


    The latter is seen as a potentially dangerous fault, as the whole point of an RCD is to cut the power in the event of an electrical fault, such as accidentally cutting through a live electrical cable.


    Another example of a C2 electrical defect is an MCB with too low breaking capacity for the installation.

    If the fault current (Ka) of your electrical installation exceeds the maximum breaking current of the circuit breakers (MCBs), this is considered a potentially dangerous issue.


    Finally, you might be issued a C2 code if the EFLI (Earth Fault Loop Impedance) limit specified in BS 7671 is exceeded on a particular circuit, as this would mean that the protective device would not disconnect the supply within the maximum time required by BS7671.

    These defects are classed as potentially dangerous and require urgent rectification without delay.

    Examples of C3 Electrical Defects

    C3 recommendations for improvement are not immediate concerns but are still recommended to be completed. You may be issued with a C3 code if part of your installation doesn’t comply with the latest regulations or amendments but doesn’t pose an immediate risk.

    For example, there might be slight damage to a light fitting, but no exposed live parts are present. Or, your consumer unit may be manufactured from PVC rather than metal. Metal consumer units are fully compliant as they resist the spread of fire.

    We quote all remedial works on an itemised basis so you can choose whether to proceed with C3 recommendations or not.

    What Happens After the Remedial Work Is Completed?

    Once we have repaired all defects with your electrical installation, then we will issue you with an Electrical Installation Certificate (EICR), or a Minor Works Certificate (MW), along with a satisfactory Electrical Installation Condition Report (EICR). These documents are proof that your electrical installation is safe and compliant.

    People Also Ask

    Do you have questions? You’re not alone! Here are some of the burning questions people often have about electrical remedial work and EICR reports.

    Do I need a new EICR after remedial work?

    Yes, after all the electrical remedial work is completed, a new Electrical Installation Condition Report (EICR) should be issued to confirm that the electrical system is now safe and compliant.

    How long do EICR reports last before remedial work?

    The validity of an EICR report varies depending on the type of property. For rental properties, it’s generally every 5 years or at each change of tenancy. For homeowner-occupied properties, it’s usually every 10 years. Remedial work should be carried out as soon as possible after issues are identified.

    Can you sell a property with an unsatisfactory EICR?

    Technically, you can sell a property with an unsatisfactory EICR, but it may significantly impact the sale process. Potential buyers may request that the electrical issues be resolved before completing the purchase, or they may negotiate a lower price to account for the required remedial work.
