GTC Avis 

6th power cut this morning. Used to get them maybe once or twice a year- these people took over and they are several times a week. Always for under 10 seconds

Customer service were useless - very inconfident - very confusing who was going to get the power on. It took them over 7 hours to arrive. Without power for 12 hours on a wet dark day. No funds supplied for a hot meal or the inconvenience.

I wouldn't even give 1 star!!
Customer service is absolutely shocking. My whole estate suffered a very long power cut over a weekend, total 48 hours off supply and customer 'care' team are shrugging it off saying we aren't due compensation! What's the care stand for in your title? They have no sympathy for their customers nor do they wish to listen. It's the winter and the reason we all suffered was due to insufficient cable installation NOT THE WEATHER. This is beyond a joke. Everyone has lost all their fridge/freezer items and has had no heating all weekend. I am appauled.

Here is honesty , I work on site and the gtc crew that do all our connections have an excuse book that never ends everyone on site thinks they are a joke ,they come one day tell you what's wrong (usually nothing so they make something up) then they tell you how to remedy it and the next day they come and tell us that what we have done is wrong , absolute joke

I have no idea who these people are, theyre not my supplier for anything but have been harassing me with unsolicited text messages multiple times a day, especially recently. I cant block unless I get i text them by an unknown number (Ends 6162).

I dont know who they bought my data from, but ive never heard of them until their text barrage about outages and getting ready for winter.

We run a small electrical firm, we need to use the GTC to set up solar panels. We wait months and months for any sort of contact only to find they have ignored our initial emails and have to constantly chase them to actually get them to do their job. This then means our customers we set up solar for are not able to use their panels and lose out on money. I am about to phone them again about a form that was meant to be completed back in May. Shock, it hasn't been. If you can, avoid them like the plague.

In 2024, I contacted GTC regarding a series of planned power cuts. The issue was not the cuts themselves but the power being switched on and off repeatedly in short bursts, which risks damaging electronic devices. I was told on 19 April 2024 that the matter would be investigated and someone would follow up. I never heard anything again.

Then in June 2025, while I was away on holiday, another planned outage took place. I returned home to find no power for an entire day. The next day, I received a letter informing me the power would be off, which was far too late to be of any use. I raised this with GTC and was told it was Royal Mail’s fault. That is not an acceptable excuse and simply deflects responsibility.

Given the state of energy prices and the reliance we all have on safe and stable electricity, this kind of customer service is unacceptable. GTC does not appear to take accountability seriously and fails to communicate with customers in a reliable or timely manner.

Horrendous. We live on a new build estate and have several power cuts a year that last over 12 hours. National grid manage to get all other houses back up within a few hours but these incompetent cowboys can't. There customer service is non existent & they offer no support if you have children or vulnerable people at home. There "live" updates don't exisist, they promise call backs which never happen. If you're considering moving somewhere supplied by these amateurs I would reconsider.

Had to report a power cut on our estate. Was given their telephone number by National Grid. I tried ringing them but gave in after thirty minutes of listening to irritating music.

Would give no stars if possible. Live on a new housing estate and at least one power cut a year sometimes lasting days. Their ‘live’ updates get refreshed every 9 to 10 hours sometimes. Always seem to manage to restore briefly before going off again so they don’t have to pay compensation. Need to look at the infrastructure when all other estates next to us manage to keep their power! Seriously considering moving home because of how bad they are!

Appalling service during a power outage recently both during and after the power was eventually restored. No customer service whatsoever! You are truly on your own during a power cut! No communication or timely updates! Genuinely unfortunate if GTC are your Network Operator as they have no interest in customer service or accountability.

Awful power cut restoration "power is restored" but it's like they've had to share out the 240v to the local area. Not enough power to turn on most lights only very efficient ones can get anything. This isn't an isolated incident either almost every time there is a power cut it takes them almost an hour longer to address it compared to other companies that supply the village. Then they must have some right cheap ways of "fixing" things cause the power will either take 5+ more hours to be repaired compared to the other providers or it will come back on but will then turn back off again later probably cause the prit stick glue they used to connect the wires was washed away in the rain. Normal service is ok but in terms of power cuts it's absolutely ridiculous.

This company has a no return policy on it's Canon MG2560 printers. It also has an undisclosed part required for a connection to the computer which is a USB Connector.
That part needs to be purchased separately.

Awful service do not rely on them in an emergency. My provider requires me to call 105 out of hours for electrical emergencies and we had one over easter weekend involving an electricity pole. They were so incredibly unhelpful and unbothered. No one, despite 3 calls to 105 could figure out how to send anyone out to me and our problem still remains. Tbh itll take someone dying I reckon until this company sorts itself out.

GTC, Dubai situated at Naseema Tower They are very irresponsible and unsatisfied dealings are providing for costumers ,If we use pamm account trade with his platform account would got any technical error or any mistake happens through drawdown our amount GTC will not take any guarantee for our loses recovery. The clarification from them account managing a third party so we are not responsible for which loses,GTC only appointed third party,client does not know any other one.we lost more than 2.5lakhs $ from this platform through our pamm account manager. So we can't trusted 100% reliable platform,as well costumer support is very very poor, So take care and keep so far for everyone is better.
These all things happened from Nov.23 onwards until now.

GTC and Barratts have been delaying fixing some streetlights on our development since they were reported faulty at the start of October and they have dragged it out and this will now go into the New Year. It has left the path dangerous and pitch black in the winter weather so you cannot see where you are go and leaving the community that uses it vulnerable which includes school children. Thankfully they've dragged this on for so long, blaming 'technical changes' that the schools have now broken up for Christmas. There is no end in sight with both parties just constantly promising updates and I have to chase to get them. Absolutely dreadful. Imagine moving onto a new build estate and all the things that are new dont actually work and there isn't any way of just dealing with one person to get the issue resolved.

God forbid you have to deal with this company and their 3rd party counterparts. Timely resolution to problems will not happen. 2 weeks without essential home utilities now

Very disorganised average company. Certainly not how they used to be many years ago. The whole thing will take too long to write. Generally just clueless.

Took weeks to reply to a simple request to check if the dangers of loose cables. A bigger DNO was able to tell me who owned it in under an hour. They simply do not care, despite the fact it could have been a live mains cable they did nothing.
