Energy Bill [HL]

My Lords, I am not sure that my noble friend answered my questions quite as fully as I might have hoped. I asked whether the suspension provisions in Clause 15 might apply to the landlord of a vacant property. It seems that repayments of the Green Deal are fixed at the outset—or am I wrong? Is there flexibility? What happens if one tenant does not use much energy and the next one does? Does the Green Deal repayment change under any circumstances? What if a tenant defaults on paying his energy bills, does the landlord become liable? I am not asking the Minister to answer everything now—I do not want to regurgitate my previous remarks—but would he consider writing to me once he has considered the issue?
