"We have used NSI to carry out all our electrical reports and upgrading where necessary. Quick and efficient. Their portal is easy and informative.
Would have no hesitation in recommending them."

We have been working with NSI for over a year, and happy with the services provided. They keep us up to date with the jobs progression and send detailed reports once the work is completed. They have been a reliable contractor and we would be happy to work with them again.

We have found NSI to be extremely pro-active when dealing with jobs sent across to them. They always act promptly and are very professional

"We have used NSI several times to complete Electrical Safetry Checks and I cannot fault the level of service that we recieve. The whole experiance from booking the appointment in, arranging access and receiving the certificate is faultless.

Will continue to use them going forward and would definatley recommend to anyone looking for this sort of work to be carried out."

Always helpful, efficient and always a quick turn around.

Great, efficient company to deal with.
