Energy Performance of Buildings (Scotland) Regulations 2025 [Draft]

I am happy to do that. The market has been through previous changes—EPCs have been updated over time—so the assessor market is used to dealing with changes to the calculation methodology, the modelling and the software that is used. We have gained good experience during the past 15 or 16 years and we know that that is feasible.
On the capacity of the market, as the cabinet secretary said, we have had a good discussion with the approved organisations. We have around 3,200 registered assessors in Scotland. Having looked at the register data of certificates that have been lodged during the last year, we can see that around 1,300 of those assessors have been active, so it suggests that there is capacity in the market to cover any anticipated increase in the number of EPCs.
Back in 2008, from a standing start, we went from around 9,000 EPCs being issued to more than 200,000 being issued during the 2008 to 2009 period. When the system first came in, the changes were far greater than any of the changes that we are proposing now. As the market has been able to address those changes in the past, that gives us confidence that it should be able to do so again in future.

Ross Loveridge will keep me right on this. Is it to go live on the 31st October next year?
Ross Loveridge (Scottish Government)
Yes. We are working to the same timetable, convener, because, as the cabinet secretary said, the UK Government is planning to make similar reforms in England...

That is helpful. Convener, I do not have any further questions on that.
The Convener

It is interesting that the majority of people have one property, but others have more than that. Do you have the data on that?
Màiri McAllan
SNP
Yes. In my scribbled handwritten notes it says that, in June 2024, 76 per cent of all registrations were for one property. I will check the source of that an...

That would be great—thank you very much. The possibility of going back to a 10-year validity period once people reach an EPC C rating is interesting. The ot...

Cabinet secretary, will you outline what the Government’s plans are for the training and availability of assessors to undertake the proposed new assessments?...

I think that it has already started, to a great extent, has it not?

Yes, it has. We are already discussing that with organisations. Versions of the home energy model are now available for approved organisations and assessor o...

Could you give us an indication of your plans for updating the auditing and assurance requirements?

Forgive me, convener, but I might turn straight to Ross Loveridge to answer that. We had a conversation about it this morning and he explained it to me very ...

Will you say a little more about smart auditing, Ross? That sounds interesting.
Ross Loveridge
Patrick Mason can explain this as well. We have a system that flags errors. For example, if an assessor submitted or lodged multiple certificates—a number th...

That is exactly right. In essence, our approach involves risk-based auditing. It looks at an unlikely set of circumstances, puts rules in place around it and...

Yes, thank you, convener. Thank you, cabinet secretary, for that insight. As you have identified, the problem is that, under the existing regulations, some c...
