How many domestic Green Deal installations have been identified where MCS certificates were not issued in the name of the homeowner; and what steps his Department is taking to deal with those cases.

The Department does not have an estimate for the scale of the issue as we do not hold details of all Green Deal loans issued. Lack of an MCS certificate has appeared as an element in some Green Deal complaints the Department has reviewed, though this has been uncommon. Officials are investigating complaints referred to the Secretary of State in accordance with the Green Deal Framework Regulations, and may issue decisions cancelling or reducing a Green Deal loan where they find breaches of said regulations or the Green Deal Code of Practice. This may include issues related to MCS certificates.

What mechanisms were in place to ensure that Feed‑in Tariff registrations were correctly assigned to homeowners at commissioning; and what support is available to consumers where feed-in tariffs were not correctly assigned.

Ofgem administers the Feed-in Tariff (FIT) scheme and maintains the Central FIT Register (CFR), which records accredited installations and their recipient, supporting correct assignment of payments. Suppliers must maintain accurate records on the CFR, which is subject to regular audit activity. In some cases, payments may be assigned to a third party under separate contractual agreements. Such arrangements are commercial in nature and fall outside the FIT framework.To confirm the recipient, homeowners may request information from Ofgem via an Ownership Register Query. Where appropriate, they may raise the matter with the relevant supplier, with unresolved complaints escalated to the Energy Ombudsman.

What assessment he has made of the adequacy of consumer transparency, accountability and protection in complex supply chains involving sales agents, installers, finance companies, insurers and certification bodies in government‑supported energy efficiency schemes.

As set out in the Warm Homes Plan, our assessment is that the current consumer protection system is too fragmented and lacks sufficient oversight of the various actors involved in the delivery of government‑supported domestic retrofit schemes. The Department is reforming the consumer protection system to simplify delivery and bring oversight under closer government control, and will consult on options for reform this year. This includes clearer accountability across supply chains, strengthened assurance arrangements, and improved monitoring and escalation processes. We are working across Government, including MHCLG, and consumer experts from industry to develop and stress test plans.
