TESUP Reviews 

You have to be pretty thick to think you will get a 10kW output wind turbine for £200! Scams only work on people that want something for next to nothing. In the UK the most basic 10kW units will cost £20,000+ 😂

Thieves & criminals! Stole my money & have now blocked me from their website so I can't continue to dispute them. I can't believe WISE excepts the EFT transfer.

Don’t buy from this company. The wind generator they sales are very very poor quality and will not turn at high wind speeds. They also will not refund your money even they have not sent out the goods. The support are useless and I have to get my credit card company to get my money back. AVOID AT ALL COST YOU BEEN WARNED…

I ordered $2,000 worth of products to receive nothing. They stole my money

October 28th 2023, i've ordered and paid for a V7 Vertical Wind Turbine (7 KW) + Low Wind Blades. An amount of 1300.00 Euro and upto today i did not receive any product. Every month, since June 2024 i write them an email and leave a ticket but they always promise that the product will come. It is just one big fake company. Please watch out and do not buy from them!

And again an automatic response, without confirmation of the appointment!!! What about the documentation for the delivered turbine - there is none at all!!!2025-10-06 01:30:38TESUP Support

No telephone number on website. I had to open an account to send a message, requesting a call-back. This was declined the following day.

Any company that refuses to speak to prospective customers should ring alarm bells. Which is confirmed by all these Trustpilot reviews.

The most worrying aspect is that HM Govt apparently permits such scammers to operate without any fear of prosecution.

This company is a complete SCAM. 6 months and counting and nothing delivered except deceptive emails. STAY AWAY

add me to the list of suckers purchasing from New Zealand (I should have clicked when the credit card failed and forced me to do a bank transfer) Red Flag missed!!

How real they are i dont know either?

If I could would give ZERO stars! products do not work, take months to be delivered. No support! No communications! No refunds!
Wind turbine build quality shocking poor, never worked and unsafe. The company is terrible is every aspect and using their legal terms and conditions to defraud customers! Tried to claim my money back and their response legally, they cannot run a variable business if they refund every time a customer claims their product does not work. This is only an elaborate marketing scram.

Tesup business closed 2024 with legal case against them from DHL

After months of waiting, being ignored, chasing, asking for a refund, treataning legal action, half of the order for a turbine arrived. Quality was poor, wiring unsafe and functionality even worse. Its now in a scrap metal skip.. save yourself the pain dont go anywhere near this company or its products.

I am not sure why there us no regulatory bodies to control on such fraudulent companies doing a daylight scams by creating professional websites to lure customers and once the customer is trapped by placing the order the company will never deliver products
There should be a complaint against Tesup london Limited for these kind of false promises 3 to 4 weeks delivery time and not delivering still after 4 months and same repeated robotic reply saying your order is in process with same pictures of work in progress sent in some email replies
You are allowed to create account on thir website and place order all communications is via the query raised in your login account
All queries are answered with robotic repeated replies saying your order in processing with no dates information for shipping.
Really frustrating and trapping customers with very high impact social media updates which are definitely false

Horrible SCAM!
No delivery No explanation

Unfortunately you can't give zero stars, I bought my Tesup Tesup ATLAS X7 and a Growatt inverter. wind turbine in 2023, it has not yet produced Kwa. The quality and construction is so poor that it will never be able to produce,

Do not buy their products they area a scam.

This is a fake company, the head office is a shared workspace in the UK, Mr Basar Onur Mesci Active

I ordered an atlas windmill in march 2025,wich I have received in may 2025 but without the inverter. 'They are working on a new version' since then. I have send them already lots of messages but everytime the same answer. No real mailadress, no phonenumber. Bad service.

This company is a scammer I was taken for $2500. I have tried contacting the IDIOTS but I get AI and no answers

Very slow response
Quite unhappy

I have been waiting for 7 weeks for my delivery. As yet I haven't even received a delivery date or tracking details. when I get in touch with the company they fob me off with excuses
