Awful after sales service

Awful after sales service. I paid for trickle vents that were not fitted with the new glazing installed in April. I am chasing this ever since being passed from pillar to post - best part of 5 months. No response from sales rep bar apologies who will "pass it on to the office" - I contacted them directly no response from office despite promises of immediate follow up. Never again.

!!!!Stay away at all costs!!!!!!!

This company is terrible, they use contractors for there installations, no consistency.

The women (sharon) I spoke to over the phone in Wexford, seems to have zero understanding or tech knowledge.

Called in a few times , got a different woman, who also has no clue,

Energlaze solar panels & battery

Energlaze fitted solar panels in 2024 and the team fitting and commissioning were so efficient and friendly.
Adding a battery today - Shane & Evan doing the job. Shane, the electrician, did the initial installation in 2024. Thanks to Peter and the team at HQ. Barry

Very dissatisfied

This company promised an app to monitor solar panels input and output after a lot of phone calls and technical support app work for a short time and then stopped!
Response from company “App not working anymore”
Our diverted has been replaced 3times as the company uses inferior products.
When the sun starts to shift e in May the diverter stops working!
It takes weeks to get contact and the response is they have no technicians in area!
Now it’s you will need to pay for technicians to call out and replace with more inferior products.
Dont believe the sales talks as I always have to pay for electricity summer and winter!!
A long time very dissatisfied unhappy customer!!
Do your research and try other companies

Avoid these guys if you can.

Avoid these guys if you can.

I got my house wrapped, an EV charger installed and the glass replaced at the front of my home.
Nothing but trouble with this shower.
Job was carried out in the summer of 2024 (date option on this site does not go back that far)

*Misquoted the grant values available to me. (Eventually refunded me the balance)
*Did not turn up on confirmed start date of the job. I'm self employed, so I sat at home for no reason thay day, earning nothing.
*Left my driveway marked after a sloppy clean up at the end of the job. When sent pictures, they denied there were marks on the driveway! They had used black paint to cover render spillage on my tarmac driveway. Driveway now covered with black sploges.
*Supposed clean up of the concrete path at the back of my house was a joke. Instead of power washing the whole path, they power washed the specific clumps of render. Looked like the aftermath of a snail orgy, ie, thin lines of clean concrete winding down my path.
*Ripped the paintwork off my window frames and ignored my complaint about this.
*Chased for full payment before the job was finished, despite claiming that the final payment would be due when the work was complete.
*Mentioned the need for scaffolding when quoting the job. I live in a bungalow. No scaffolding was used but the price remained the same. (They used a small elevated platform on wheels).
*Refused to disclose how much of the cost was paid to the contractor and how much was their fee.
*When reinstalling the gutting at the end of the job, I had to go and get parts because the contractors van was broken down. These parts were paid for by me and not reimbursed, adding to the overall cost.
*Their engineer was pig rude in my home.
*Left external sockets disconnected. (Reimbursed me over a year later for the cost of reconnecting them)

I could go on and on. Absolute disaster of an outfit.

These are just middleman, who do not advocate for you, the paying customer. They are just an additional cost on top of the contractor. Find a contractor directly if you can.

Efficient, Professionalism and Quality Product

From the start of the process when we first met Dave until the last element of the installation was completed by Ger, Gordon and Eoin, I have nothing but good things to say about Energlaze, their staff, products, efficiency and professionalism. I would recommend Energlaze in a heartbeat. We got numerous quotations and Energlaze were winners on every element without doubt!!

Very prompt reply to my online query.

Very prompt reply to my online query. Thomas (the salesman) came to my house within a week and gave me a quotation to replace the glass in all my windows.
I accepted the quotation and had all my window glass
replaced on 7th January 2025. The 2 lads who did the job were brilliant. Everything was completed within a few hours. My house feels much warmer since the windows were upgraded. I have had a very positive experience with Energlaze and i would highly recommend them to anyone considering an energy upgrade of their home.

Everyone from Maria to Pat and the fitters were very helpful and were very good at their jobs. The men worked in poor conditions (rain) but completed their work very well and left the house spotless.
We will have you back in the future to do our windows at the back.

Bad customer service

-Got a hand written quote so missed that they had put the window colour in as cream
-The installers were great and flagged this issue...but even though they rang the office to contact me (I was at work) they didn't contact me.
-I rang the sales rep, who started making excuses and eventually said it was a mistake and he would get on to the office and see what could be done
-Next thing the installers rang to say they were coming to finish the job (still the wrong colour) ...and then told us they would hold off when they realised we hadn't been InTouch with the office
-Eventually got through to the office who said they would sort it. It has been 2 weeks with no updates and when I rang them today they said they were going to replace the windows had already ordered the new ones (without contacting me so I didn't have a chance to flag that we weren't given choices for the likes of handles and I didn't like the ones that came, and also there was another error with some of the windows that should have opened not opening....they said this wasn't in the original quote so I would have to pay more (the original quote was to replace what was there so, so I don't know how they could that) also since the installers thought they were coming back they left other jobs unfinished so we were living in limbo.
-In the mean time (just after the original installation) the sales agent rang again, flat out lied and got aggressive on the phone.
-Also just to note, I am not really happy with the front door, it takes 2 hands to open, which slows the process as you need can't have shopping etc with you, and it can't be left on the latch
Would not recommend this company

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 .

They have no technical staff at all!Buyer beware don’t do business with these cowboys masquerading as a reputable company!
