What is electrical contractors insurance?
Electrical contractors insurance protects firms that install, test, inspect and maintain electrical systems. A typical policy includes public, employers' and completed works liability, cover for tools, test equipment and materials, and contract works, with professional indemnity available for design and inspection reports.
The largest exposure for most electrical firms is not on the day of the job. It is a fire, shock or power failure that traces back to an installation months or years after handover, which is why insurers ask how your work is tested, certified and recorded. The same cover extends to lighting installation, street lighting contractors and lightning conductor specialists, each of which insurers rate on height and location.

What does electrical contractors insurance cover?
Electrical policies are built around three moments: while you work, after you leave and when someone relies on your certificate.
Public liability
Injury to building users and the public, and damage to clients' property while you work, such as drilling into a water pipe or causing a power outage that damages equipment.

Completed works liability
Fire, shock and property damage caused by an installation after you have handed it over, often the costliest claims an electrical firm sees.
Read more about products liability cover
Employers' liability
Injury to your electricians and apprentices from shocks, falls from ladders and towers, and manual handling.
Read more about employers' liability insurance
Testing and inspection
Claims that an inspection report missed a defect, which some liability policies restrict and professional indemnity can pick up.

Tools and test equipment
Power tools, cable pullers, calibrated testers, thermal cameras and meters, whether on a job, in an engineer's van or back at stores.
Materials and stock
Cable, switchgear and fittings held at your stores, in vans and delivered to site before they are installed.
Contract works
Your installation on site until handover, where the contract makes you responsible for it.

Specialist installations
EV charge points, solar panels and battery storage, which insurers rate separately and need declaring.

Legal expenses
Costs of pursuing unpaid invoices, contract disputes and employment claims, depending on the policy.

Covers electrical firms often add
- Fleet insurance: for engineers' vans, with tools cover kept on the trade policy
- Commercial combined cover: for your offices, stores and stock at the base
- Cyber insurance: if you install or monitor networked building controls and security systems
- Group personal accident: weekly payments while an injured electrician recovers

How much does electrical contractors insurance cost?
Insurers rate electrical firms on where they work and how much of their work others rely on later. These are the factors that matter.
Type of work
Domestic, commercial, industrial and specialist work are rated differently, and work in hazardous areas or on high voltage systems is rated separately or referred.
Testing and design share
The proportion of turnover from inspection reports and design affects whether professional indemnity is needed and how it is priced.
Wage roll and subcontractors
Electricians, apprentices and office staff are rated separately, with labour-only subcontractors usually counted as employees.
Specialist installations
Solar, battery storage and EV charging carry their own fire and roof work exposure, so insurers ask for turnover from each.
Tools, test kit and stock
The value carried in vans and held at stores, and how they are secured overnight.
Claims and certification
Past fire and damage claims, and whether every job is tested and certified with records kept.
What electrical contractors insurance does not cover
Exclusions on electrical policies often depend on where the work was done. Check these before you sign.
- Work in hazardous areas such as fuel stations, chemical plants or explosive atmospheres, unless declared and agreed
- Work on aircraft, airside, rail, offshore or nuclear sites, unless agreed
- Financial loss from a missed defect in an inspection report, unless professional indemnity is included
- Rewiring or replacing your own defective installation, even where the resulting fire or water damage is covered
- Solar, battery or EV work that was not declared to the insurer
- Tools and test equipment left in vans overnight without meeting the policy's security terms
- Accidents involving your engineers' vans, a matter for commercial vehicle insurance
Specialist electrical policy or a general builders' policy?
Some electrical firms are insured on a general construction policy. These are the areas where that can leave gaps.
| Feature | Specialist electrical policy | General builders' policy |
|---|---|---|
| Installation fires after handover | Rated as the main exposure | Covered, but with the electrical risk not always fully declared |
| Inspection reports | Included or offered as an extension | Often not contemplated |
| Design of installations | Professional indemnity available alongside | Rarely offered |
| Test equipment | Calibrated testers and meters specified | General tools limits only |
| Solar, battery and EV work | Underwritten with specific questions | May be excluded or not declared |

How much does electrical contractors insurance cost?
It depends on the type of work you do, how much is testing or design, your wage roll, turnover, specialist installs such as solar or EV, tools values and claims history. Industrial and hazardous area work is usually rated more heavily than commercial fit out. Insurers weigh these differently, so comparing several is worthwhile.
Are we covered for testing and inspection work?
For injury and physical damage, usually yes. If a client says your inspection report missed a defect and they lost money as a result, that is closer to a professional claim, so check whether the policy includes inspection work or add professional indemnity.
What if an installation we did causes a fire years later?
Completed works liability covers injury and damage caused by your installation after handover. Because claims can surface long after the job, avoid gaps between policies and file the test certificate for every installation.
Do we need professional indemnity for designing installations?
Usually, yes, if you design systems, size cables and protection, or sign off designs for others. Liability insurance will not pay when a sizing or design mistake leaves the client out of pocket without any physical damage. Professional indemnity fills that gap and is often arranged alongside an electrical policy.
Are EV charger, solar and battery installations covered?
Usually, if declared. Insurers ask for the turnover from each, as roof work and battery fire risks are rated differently from standard electrical work. Undeclared specialist installs can leave a claim unpaid, so tell the broker before you start offering them.
Is our test equipment covered?
Under the tools section, yes, as long as the values are declared. Calibrated testers, thermal cameras and power quality analysers can be costly, so list high value items and check the limit for any one item and the overnight security terms.
Can we work in hazardous areas such as fuel stations or chemical plants?
Only if the insurer agrees. Most electrical policies exclude explosive atmospheres and hazardous sites unless declared. Insurers may ask about training, permits to work and the share of turnover, and some will refer the work to a specialist market.
Does our policy cover damage to pipes or cables we drill into?
Public liability usually covers damage to the client's building and services, such as a pipe you drill through, subject to the excess. Damage to the part of the installation you were working on may be excluded, so check the property worked upon terms.
Are street lighting and lightning conductor contractors covered?
Yes, if declared. Street lighting installation brings highway work, column erection and buried cable strikes, while lightning conductor contractors work at height on steeples and towers. Insurers ask about traffic management, access methods and maximum working height before agreeing terms.
