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

22 month update

I am updating my review as I promised I would when my issues were finally resolved. ( I was asked several times to take my initial review down, but didn't) I have waited 22 months since Installation on Aug 2nd 2024 to be able to export to the grid as promised at POS. As of today I have received a notification from Octopus to say I am now exporting! Hallelujah! The journey has been totally tortuous waiting for NWR to get the correct paperwork to us. Initially I gave them a 1* rating after months of waiting, it would have been zero if possible. But after 22 months of endless calls, emails, reviews, WhatsApps, trading standards and tears we have got there! So I'm keeping my end of the bargain and updating to a better review. Recently there has been a definite seed change in how the company works. After countless Customer success managers, who no doubt tried their best in what was a failing service, we finally got people who did what they said they would after hundreds of empty promises. Technician Ben deserves 5* for his efforts actually on the ground, installing the panels and dealing with the faulty battery and eventually installing the new one. However we now learn it should not be in our roof space for safety reasons- and may affect our house insurance! Also earning 5* for their efforts should be recent employees Salma and Zack , both of whom have kept good communication with us and done what was needed. My gut instinct tells me they have turned a corner in terms of customer and operational service. So, to any future customers I suggest you read the many reviews on here and just be aware of possible pitfalls. Checking them out on Companies house is also interesting ...and possibly bears out the seed change in approach and efficiencies. Hopefully you will get success without losing 22 months of your life and sanity, like us!

Remember to get a cam certificate if…

Remember to get a cam certificate if net you will not be able to sell the excess electric Bach to the grid unless you pay £1000.00 for it to prove the equipment is compatible the electric still goes back to the grid so if must be compatible you just don't get payed
