NRG Bet Promo Codes Tested & Reviewed
NRG Bet are not a household brand in the UK betting market, but with bonus codes offered to customers, it is taking steps to grow its market share.
Below we detail what those promo codes entail, to see if you are tempted to give it a shot.
⚽ Sports Sign-Up Promo Code - b20g10
Unlocking the NRG Bet new customer bonus is very simple. Sign up with the bookmaker, ensuring you quote "b20g10" during that process to set the wheels in motion.
The code is apt too. Why? Well, because "b20g10" is an abbreviation of bet £20 and get a £10 free bet. As with a lot of promotions, there are caveats to the bonus.
The main thing being that your qualifying bet has to be placed against odds of 1/1 (2.00), or higher, and be settled inside 24 hours of sign up.
The deal isn't perfect, mainly because of the quick turnaround but a 50% deposit bonus is tough to sniff at.
The other point we should stress is that you will not get this deal by going direct to NRG Bet. With that in mind, we have a dedicated section on how to get started with the welcome bonus.

🎰 Casino Promo Code - nrg100
NRG Casino has a pretty solid casino welcome offer using the promo code "nrg100". In this, you need to deposit £25 and wager a minimum of £25 on Big Bass slot games to receive 100 free spins on Big Bass Bonanza.
The deposit amount is fairly high to get 100 free spins, but it gets worse as they also come with 10x wagering.
Instead, we recommend our list of the best no wagering free spins bonuses, while taking advantage of the sports welcome offer instead if you choose to join NRG.

Free Spin Fun
This sort of existing customer promotion is not exactly a rare feature across casinos. It's still a noteworthy bonus though.
NRG Bet will highlight a certain game(s) each week, where your wagering on that game will earn you free spins. The more you wager on that slot game, the more free spins you get.
Spin between £10 and £20 and receive 10 free spins, which is worth £1. Wager £100 plus, and you'll earn 100 free spins, worth a total of £10.
🔢 Our Rating: 4/10
