Short but good experience

(4.8 / 5)

  I only went through the ordering and cancelling
process with Startex Power, but it was a
pleasant one. The online ordering system is
very fluid and doesn't feel cumbersome.
Unfortunately I needed to have power within 24
hours and was unaware that Starpower DOES offer
that service, and we signed up with another
company and had to cancel the service with
Starpower. The customer service person was
very friendly when I made this request and she
did explain to me about that 'priority service'
but understood my situation and cancelled the
service with no penalties or issues.

I recommend startex power simply based on the
fact of great customer service, their modern
online services, and their good rates. I'll be
switching to them once my term with this other
company expires.

  I have been with StarTex almost two years and am completely satisfied. Their rates are always competitive, particularly when you add the hidden fees to other company's rates. I definitely plan on renewing my contract.

Great Company / But..

(4.8 / 5)

  Had Startex for about 1 yr. Never had any issues. Only issue is that to get a good rate you have to change to a new provider as they don't offer the best rates to present customers.

Hello, I hate to see you have left the StarTex Power family. To clarify, we do offer the same rates to existing customers and new customers. Please don't hesitate to contact me directly at jennifer.lewis@startexpower.com once your current contract expires with your new provider, as I'd love to see what we can offer you at that time in an effort to bring you back to the StarTex Power family. Take care!

Never had any issues

(4.8 / 5)

  I have been with Startex for a couple years or more now, and have never had any problems with their service. Always helpful over the phone and have made it easy on me every time I've had to renew. And, from what I can tell, their rate is not always the lowest listed on "Power to Choose", but their cost is pretty straightforward...where as other companies appear to have quite a few different underlying fees. I try to find a reason to leave, but they keep pulling me back in ;-)

So Sad to Change from Startex, but Renewal Rates just weren't competitive

(4.8 / 5)

  I have nothing but absolutely positive things to say about Startex. Their billing is easily read and accurate. Their signup prices were competitive and their minimum usage fee kicked in at a much lower usage than other companies. They were extremely helpful in their signup and the only time I spoke with customer service, which was to ask about renewal rates because my contract is ending, they were extremely polite and helpful. I was only on hold for maybe 2 minutes and the young lady who helped me was exceptionally polite and knowledgeable. The ONLY reason I'm having to leave is because they are offering me an increase in my current rate for the next 12 months and they are quite a bit higher than some of the new contract prices that other companies are offering right now. However, I had intended to stay with them if they would have maintained my current rates so if you are a new customer, you cannot go wrong with their service or prices!

Very happy

(4.8 / 5)

  We've been with StarTex now for over 2 years and have been very happy with them. We originally signed up due to the high customer service ratings after web research. The rates are competitive (we always look for 12-month fixed rates), not the lowest, but then again, I don't mind paying a bit more for great service like this. It's time for us to renew again and after comparing the fixed 12 rates at our 2000KW/h usage level, StarTex wins again. Thanks StarTex, keep up the good work!

Great service for years

(4.8 / 5)

  Overall I have had great service from Startex since I switched from TXU in 2009. TXU failed to notify me my contract was up and switched me to a monthly rate. At first I thought the high bills was just the hot Texas summer, but then I discovered I had been paying exorbitant rates with them after years of loyalty. So I decided to switch, did plenty of research and at the time found Startex to not only have great rates, but one of the lowest monthly base prices (this is where many companies get you - if you use below a certain amount - Startex is below 499 kWH - many others are below 700-1000. I use less than 499 about 2 months out of the year, but less than 1000 seven months out of the year.) Anyway, they have always sent me a notice when my contract was about to expire and at renewal my rates have dropped even lower each year. Recently, my husband left and divorced me and I needed to switch service into my name. The first rep I talked to when I called wasn't quite as helpful as others, but told me I needed to wait until closer to the end of the contract. When I got within the time frame I called back and got a wonderfully helpful rep who helped me open my new account and didn't charge any deposit fees. I'm also impressed that when people do post complaints on here they always respond - most other companies don't.I was actually being invited to join an MLM energy company, but after doing my research, decided not to do so and stay with Startex. (And yes, I am a REAL customer).

Headache Free Service

(4.8 / 5)

  We got 1 year contract with this company by a friend's recommendation and never had any issues though we were skeptic for every new energy company that we hadn't been with. We even moved between our contract term and they were so easy to transfer the connection and even let us have energy at both places for few days while moving. Great customer service. Highly Recommend them.

Startex came through

(4.8 / 5)

  After seeing that "most" companies are charging 9.95 fee for usage less then 1000kwh including Startex I found 4 other plans that did not and planned on changing. When I called in to changed I told them they would have to leave me with the current usage fee of 4.99 for usage lessfor then 499Kwh to stay with them and they said yes! I am sure every apartment owner is upset with these new fees but show around and call Startex before you switch and politely ask. Maybe they do want to keep their Apt customers after all.

Excellent Customer Service

(4.8 / 5)

  In my experience, a power company is a power company is a power company. The differentiators are price and quality of customer service--that's where StarTex shines. StarTex offers great prices and the company has excellent customer service. I couldn't be happier with my service.

No problems

(4.8 / 5)

  I'm only on this site because it's time to renew and rates have gone up slightly - just seeing what else is out there. It's interesting to read all of the bad reviews for StarTex - most of which seem to center on customer service. I've been a customer for three years and haven't had any issues with power delivery. As such I haven't had to call customer service. So - take that for what it's worth. Power delivery = great. Customer service = haven't had to deal with it so by default I'd have to say it's fine. If you're looking for a good rate and reliable service I'd recommend StarTex.

Easy

(4.8 / 5)

  I signed up for a six month plan and everything went smooth. Connection, (online) billing and payment, and disconnection when I moved out all went smooth and without surprises. I had great service every time I called customer service. They didn't have the best price, but I would rather pay an extra cent/kwH than have to deal with incompetence.

Happy Customer

(4.8 / 5)

  Startex power was great. I used them last few years and ended 12/2015. I rated them 4 lamps because I was billed an early termination fee that was supposed to be waived since I moved. I spoke to 3 different Customer service reps about it and I was told all was good every time until the next rep would call to get a $49.50 payment. I just received a call from a collections agency, claiming I owed the $49.50 again and told her the story. She told me to email her the Info. I called Startex Power, spoke to another kind service rep,( they have all been kind and helpful), told him what was going on, like so many times before and he said he sees all the notes but that the cancel refill had not ever been filed. He was doing it now and they actually owe me 50 cents since I over paid my last bill. So they were a good company I used for years until I moved in with my fianc. I would still use them but he has a contract With another provider.

unable to change plan

(4.8 / 5)

  Historically happy StarTex Power customer, but received current bill. Last month we went over in usuage: 5297 kWh. Last year we only went above 2000 twice. Bill was very high. Called hoping something could be worked out, I even asked for any suggestions. Only suggestion was watch a tape on how to use electricity, ouch! Looks like I will have to change companies to save money. I wish they could have offered something.
