Be aware

I was hoping to be in a position to write a glowing review but unfortunately Energlaze and their complete lack of customer service prevents me doing that . We had a sales rep come out to quote for new windows and doors. He was very nice and knowledgeable . I received a quote but the number of windows was incorrect ,the make up of the quote ie type of glass and frame were not quoted correctly either . The straw that broke the camels back , we have a window section with panels rather than glass in the apertures . I asked if they could provide a solution as we intended to change frame color, the sales rep sent my request on to a manager , he copied me on the email and the manager replied again copying me on his response which I don't think he realized he was doing . The response to the sales rep read " We will worry about that later, just get the deposit " . I still have the email . I raised this with the customer service team . I received a call from the rep apologizing with the quote I originally asked for , he went on to offer me a substantial discount if I signed up there and then. A very high profile company , my advice is shop around .

Install in Kildare

Really good at attention to detail and always kept us up tp date with what was going on. Installers were really helpful and did a great job. Windows and door look great.

Energlaze are an appalling company! It took 2 years for them to replace a faulty battery under warranty.My wife and I who are both disabled went through hell!They are only good at taking your money. They have no technical staff at all!Buyer beware don’t do business with these cowboys masquerading as a reputable company!

One-Stop-Shop

We contacted EnerGlaze to discuss a one-stop-shop energy upgrade of our house which was a 1980 BER D1. Having been in touch with a number of companies, we settled on EnerGlaze due to their excellent customer service. They helped us through every step and were accommodating when arranging subcontractors to suit our schedule. We're very happy with the end result and the house is now A1 rated.

Excellent service and workmanship

From inquiry to completion we were dealt with by professionals.
Hard to fault this company.
Starting with an excellent demonstration of the product, samples and brochures for clarification, costings which never varied, measurement that were exact and regular updates regarding delivery, followed by a professional tidy installation, including removal of all debris.
You don't often get this type of service!

Terrible aftersales service

Terrible aftersales service! We paid €11,000 (after grant reduction) for our Solar installation. The system stopped working on 27 January 2025. It took them 30 days to send an electrician who diagnosed a faulty inverter. We are still waiting and have been paying full electricity bills for 81 days now while the sun keeps shining and our Solar Panels lie defunct.

Atrocious After Care

My mam got her solar panels installed a few years ago with a water diverter and she loved the constant hot water even in the depths of winter.
A few weeks ago it stopped working and despite numerous phone calls and emails from myself and my mam we are still no further along in getting it sorted. My mam is nearly 70 and has had no hot water for almost a month now.

The after care is absolutely atrocious and non existent. The ladies who are on front of house try their best to help but there is nobody to talk to besides them.

Sort the after care out ASAP

Save your money or go elsewhere

Save your money or go elsewhere. After service and support is dire.
As it the huawei solar app or whatever sales pitch they will give you on it.

Excellent Service Provider

We used Energlaze twice - windows and deep retro fit. They were excellent in the installation, managing contractors and the administrative support for the SEAI grants.

For any of this type of work I would use and straongly recommend Energlaze

All round good experience

There was good contact from Energlaze before and after installation. The installation team were pleasant, efficient and conscientious. We couldn't have asked for more.

We contracted energlaze to replace patio sliding door, front door, and to upgrade our windows with low-e plus heat retaining glass. Our journey with energlaze was very professional from start to finish. The team at all stages were informative and hard working. Bottom dollar, our house is warmer, condensation gone from inside the windows, and most important my better half is very happy, with the completed project. Finally dare I say it, yes, we had to turn down the thermostat for the heating.
