	RE: Voice from the future. By Toodles, 5 days ago Forum Well & Truly Off The Grid
	@majordennisbloodnok This app is the one that HMRC wish everyone to use, it appears to be the only route from the combination of options I have to use. I only have a passport for ID porpoises - never ...

	The requirement for me came from the following document. Attachment : Screenshot 2026-06-11 at 09.52.46.png
	RE: Surge Protection Devices By JamesPa, 5 days ago Forum Air Source Heat Pumps (ASHPs)
	The first question to ask is, does it? What does the latest Vaillant Installation manual actually say? Bear in mind that some tradesmen speak out of the wrong part of their anatomy!
	RE: Surge Protection Devices By Batpred, 5 days ago Forum Air Source Heat Pumps (ASHPs)
	@jamespa I fear the average installer will not question it. The way it was explained to me is that it is required by Vaillant for the warranty. But then the detail was that there is an inverter insid...

	@trebor12345 @batpred My version of the Vaillant installation manual, from about 2 years ago, has specific requirements for RCD type if an RCD is specified for the installation (which is fair enough)...
	RE: Surge Protection Devices By Batpred, 5 days ago Forum Air Source Heat Pumps (ASHPs)
	@jamespa Vaillant have specific requirements in term of RCD type and MCB curve. Contactum sell these types of RCBOs in 16A for £25 (in boxes of 5). I am yet to see information from Vaillant requirin...
	RE: Voice from the future. By Majordennisbloodnok, 5 days ago Forum Well & Truly Off The Grid
	@toodles, are you sure the app is an official one from HMRC? From what you've described, it's unlikely to be otherwise but worth a check first. As for @transparent's and @jamespa's points, I agree tha...

	Manufacturers requirement.
	RE: Surge Protection Devices By JamesPa, 5 days ago Forum Air Source Heat Pumps (ASHPs)
