ReviewTerminal Summary

Nationwide Renewables has a severely damaged reputation (2.7/5) due to critical failures in post-installation documentation, lack of required MCS certification, and poor customer service, though installation quality itself is sometimes praised.

What customers love

  • Installation work quality and speed when completed by technical teams
  • Individual staff members (Emma, Selma, Ben, Zack) providing exceptional personal support and issue resolution
  • Responsiveness when customers escalate complaints or involve third parties

Common concerns

  • Systematic failure to provide legally required MCS certificates, EIC, and Building Regulations documentation for 12+ months after installation
  • Non-compliance with National Grid standards (G99/G100), creating unsafe and non-compliant systems that pose fire risks
  • Aggressive retention of customers through harassment, conditional compensation offers tied to review removal, and false promises of resolution
  • Loss of MCS and RECC accreditation in 2024, leaving customers unable to access feed-in tariff payments and facing £250+ additional costs
  • Widespread issues with grid connection setup and Octopus Energy registration despite being marketed as partners
  • Systematic pattern of making promises at point-of-sale not honoured post-installation (tariff switches, certifications, repairs)
  • Property damage (driveway, roof leaks, cladding) caused during installation with no accountability or repair
  • Impossible to contact; calls unreturned, emails ignored, blocking customers and using GDPR non-compliance

Instalation very good but after service…

Instalation very good but after service terrible. Im still waiting for paperwork so I can go onto Octopus because this compay have not provided an MCS or Flxiorb certificate. On checking this company is not MCS approved so buyers beware it will cost you an extra £250 to get these documents for which you have been told by Nationwide they will sort. Then when you try to contact them you get no response. I feel as if I've been scammed by Yorkshires so called NO1 renewable energy supplier

The organisation needs improvement.

I was told by the company employed to install the solar panels they had been given the wrong instructions, so the installation took 12 hours instead of the quoted 5 hours, half the installation was done in the dark. The battery supplied was wrong and was replaced about a week later. The original inverter was also wrong and the correct one fitted about a week later. Eventually the installation was all correct but the organisation was very poor hence the 2 star rating.
