Rauvitherm Reward Scheme – REHAU Rauvitherm Connections

What is REHAU Connections?

REHAU Connections is a points-based loyalty scheme open to installer companies purchasing REHAU RAUVITHERM pipe.

How does the scheme work?

Every time your company purchases a length of REHAU RAUVITHERM pipe you earn Connect Points which can be redeemed in exchange for items on the REHAU ‘Redeem and Select Rewards’ page.

rauvitherm intersectionHow do I earn Connect Points?

Connect Points are assigned every time a purchase is made and logged by your company online. A copy of the purchase invoice or order acknowledgement must then be sent to REHAU Connections for approval via the Freepost address, fax or email.While awaiting approval, the Connect Points will appear as ‘Pending’ on your ‘My Account’ page meaning that they have not yet been added to the account balance.

Once your invoice is approved the Connect Points will automatically be transferred to the account balance and can be redeemed.

How do I create an account?

To create an account all you need to do is go back to REHAU Connections homepage (www.rehauconnections.co.uk) and click ‘Register here’. From there you’ll be taken to a page where you can register/create an account.You only need to create an account once. Or Click on the Register button below.

How many Connect Points can I earn?

The number of Connect Points you can earn is dependent on the purchases made; there is no limit applied whilst the scheme is running.

How do I redeem my Connect Points?

To redeem Connect Points you need to go to the ‘Redeem Points & Select Rewards’ page (This will appear as a tab at the top of the page, once logged in).
