Hi @mikegdavis

Unfortunately energy suppliers are only obliged to offer a 12 month guarantee.

Thank you am looking at ivie bud to replace 

ivie bud or Hildebrand Glow IHDs are both good replacements. I’ve used both but eventually stuck with the Glow coupled with the Bright app. My unit was pre-set from my Bright account and so it was just a case of switch on and connect Wi-Fi 

This one is worth looking at

@BPLightlog has some experience of using it and is a regular poster on the forum. 

This is their app and is worth signing up for beforehand if you decide to order it

It's also worth noting that the Secure Pipit 500 has reached End of Sale. Secure no longer makes them so a like-for-like swap is no longer available 

OVO have said they will replace my IHD but ‘currently heavy demand’

Same here, must be some waiting list, as I raised the issue over a year ago. I keep getting fobbed off whenever I raise a stink about it. Considering the the IHD they initially supplied me never worked out of the box, it’s a bit of joke they can’t replace it.

It’s a combination of a waiting list, lack of options for S1 and massive demand for S1 capable IHDs I’m afraid.
