What people say?


Rob Hankin


I have a BMW i3 which has, until recently, always been recharged using a 13 amp socket. While this has worked satisfactorily, for the most part, there is no doubt that the 10amp recharge rate was tediously slow. I investigated the alternatives for an improved charge rate and decided that one of the best options was the charging solution offered by Rolec. In my opinion, the BMW charging unit is unreasonably expensive, far too big, and not very attractive. With this in mind, I made a request to NSN, of Penzance, to visit my home and come up with some proposals.

Joss, of NSN, came to site at short notice, and we soon agreed what was necessary and how best to proceed. Subsequent to this, the NSN installer brought all the necessary parts to my home and quickly, and efficiently, fitted the Rolec socket, armoured cable, and associated accessories. He completed the whole assembly, which involved installing the socket some distance from my house, within a morning, and almost all the interconnecting cable is out of view. So a neat job.

The i3 now charges at 33.1 amps (measured by me), so more than three times faster than before. I am extremely pleased with the professional way in which the whole installation was carried out, and the way that NSN attended to the OLEV grant paperwork.

NSN Electrical installed an EV charge point at my holiday cottage, and I was extremely impressed by their service from initial contact through to completion. Joss was very helpful in his advice and came up with a neat solution to placing and supply of the charge point. Both the initial visit and the installation were arranged at convenient times for me, and the whole process was smooth and professional. I look forward to using NSN Electricals for all future electrical work at the cottage.

Carlyon Court Management Company Ltd

NSN Electrical undertook a contract to replace the External Lighting and Control Systems for Carlyon Court Management Company at 91 Sea Road, Carlyon Bay in the summer of 2018. This consisted of replacement of the Lighting for the Gardens and the Car Parking areas. Prior to work commencing we had two site visits from NSN so as to ensure that all of our customer needs were accommodated, and suggestions were made to upgrade and enhance the installation. The work consisted of removing the existing lighting bollards and the in-house control system, during this time several faulty and damaged cable were discovered and were replaced as per industry standards. The new system consisted of state-of-the-art non-corrosive lighting units and the re installation of PIR sensors and the control equipment to better suit the needs of the facility. All work was carried out in a quality manner and close communication was ensured throughout the period of work to ensure and cater for customer wishes.  The staff of NSN were found to be competent polite and helpful at all times which facilitated a positive experience. The completed job resulted in a high degree of satisfaction from all residents and we would not hesitate to use this company again and would be confident to recommend NSN Electrical to others.

My husband and I have had a tricky time with the installation of our EV charging point, all sorted out thanks to the infinite patience, expertise and fine work of Joss and his team. We cannot recommend them highly enough.

Mrs Hugh

Thank you NSN Electrical for completing the re-wiring of our house. Your team were excellent throughout. Very reliable and kept in contact to advise us of any schedule changes which may affect the customer. Options were agreed in advance and at no time was there any disruption. I had every confidence in their honesty, reliability and qualifications. The work was to a very high standard.

Jonathan & Jackie Braithwaite

We have called upon the services of NSN Electrical Ltd on a number of occasions and have been extremely impressed by the pro-active and efficient approach of the Company (emails are dealt with promptly, telephone calls are returned and timely and appropriate appointments are made ) as well as by the knowledgeable, helpful and efficient manner of the individual electricians, who have undertaken work for us—nothing is ever too much trouble and problems have been explained in terms that we have understood! We shall certainly continue to rely upon NSN as need arises and would have no hesitation in recommending the Company to others.

Tony & Esther

NSN provided a great service when installing some new electric storage heaters. We have known Neil Stevens for many years – he is 100% reliable. He visited the property to provide a quote, and scheduled the work at an agreed time. His colleagues turned up on time, completed the work as promised, and it is all working fine.

As an Interior Designer and Project Manager, I have worked with NSN for a number of years now, on both personal projects and those for clients. I have always found them super reliable and highly competent in whatever task I have asked of them. They are also very flexible working to tight time constraints and around other trades and conduct themselves really professionally.
