The Health and Safety at Work Act 1974, the Workplace (Health, Safety and Welfare) Regulations 1992, the Provision and Use of Work Equipment Regulations 1998, and the Management of Health and Safety Work Regulations 1999 form the body of legislation governing electrical safety in the workplace. The Electricity at Work Regulations 1989 also state that “all reasonable and practicable steps to prevent danger from electrical systems” must be undertaken.

We will advise you of the frequency of electrical testing and inspections required based on the nature of your business.

Our comprehensive planned electrical test and inspection service enables you to remain fully compliant with legislative requirements, protect your employees and visitors, and manage your infrastructure assets.

We only employ highly qualified electrical engineers, and conduct electrical safety testing and inspection services to a wide range of customers across the UK in retail, commercial, domestic, and public sectors.

We NEVER outsource remedial work, and undertake all follow up electrical work ourselves. You only need to deal with us from day one to finish, meaning no time-wasting, a transparent service, and reduced costs.


An award winning specialist electrical safety company. We operate nationally working alongside a vast array of letting and estate agents.

Our aim is to offer a streamlined simple route to electrical compliance. Our extensive knowledge and team of skilled electricians ensure a smooth efficient process from first contact with our amazing office staff to completion of the job.

"A Personal Approach With A Professional Service"

Company icon


At NSI we prioritise electrical safety testing, unlike other electrical firms, whose primary focus is large installation works.

72 hours turnaround icon


You will receive a digital certificate within 72 hours of job completion with a quotation for any remedial works that may be required.

Remedial works icon


We don't subcontract any work, and everything is completed in-house. All required remedial works will be evidenced with a photo to ensure complete transparency.

Client portal icon


Never lose a certificate again. You will be supplied with unique log-in details to access all certificates in your dedicated client portal.

Engineers icon


All engineers are directly employed by NSI, and will always be dressed in branded uniform with company ID badges. Due to the network of engineers we have available, sickness and absence issues can normally be covered by another engineer vastly reducing cancellations or rebooks.

Ease of contract icon


Our highly trained office staff are always at hand to aid you with any questions or queries. We have a bespoke CRM system that ensures all company processes run smoothly and efficiently.
