I agree with the noble Lord. Perhaps I should rephrase what I said. I was not for a moment suggesting that he would ever do anything on a whim; he would do things only in a careful and considered fashion. I will not comment further: following the previous five SIs I think we are on to dangerous territory. The noble Lord makes a valid point and I think that we are on the same page here, although we are perhaps looking at the issue from different angles. My suggestion is that the check and balance approach that we have adopted does not mean that when councils make an application for more than 20% of the area it will be rejected, but consideration will of course be given to the application as submitted.
The noble Lord, Lord McKenzie, also referred to the problems that have arisen and asked whether we were seeking to highlight any specific ones. The noble Lord, Lord Best, talked about his experience in Newham. Of course, the Newham scheme was introduced only in January 2013 and the other scheme that I alluded to in Barking and Dagenham was introduced only in September 20014. In answer to the noble Lord, Lord McKenzie, it is too early to make an assessment based on robust evidence, and that is why the Government are strongly inclined to ensure that we review this policy in 18 months’ time. As we move forward in this respect, both the contributions that have been made in this debate and the concerns that have been raised will, I am sure, be considered as part of that review.
The noble Lord, Lord McKenzie, also raised the issue of guidance. I think that I made the point that we will shortly be publishing guidance for local authorities on the additional criteria, and perhaps some of the questions will be answered in that. More importantly, it will set out the information that local authorities will need to give if they want to apply to the Secretary of State to confirm a particular designation.
On the evidence base, of course various consultations were carried out. Various people also gave evidence to the CLG Select Committee and perhaps I may quote one. On deterring investment, Andrew Cunningham from Grainger said at the CLG Select Committee hearing in 2013 that,
“the introduction of licensing that Newham has done is for an organisation like ourselves a very heavy stick. There is no incentive for an organisation like Grainger to invest its relatively scarce resources into a borough like Newham. There is no incentive for a landlord like us to stay there”.
That has in part also been noteworthy for the Government but, again, I emphasise that we will be reviewing the implementation in 18 months’ time.
The noble Lord, Lord Beecham, raised a series of questions on definitions—for example, the definition of a high proportion of privately rented properties. It is estimated that nationally the private rented sector makes up about 19% of the total housing stock. Therefore, where an area contains a private rented sector higher than 19%, this may be taken broadly as an indication of a high proportion of properties in the private rented sector. However, we have been very careful not to specify a particular figure which would be considered to be too high a proportion for the private rented sector, because we recognise that there may be regional differences that influence what is considered to be a high proportion of properties in this sector. Therefore, our view is that it is really for local authorities to determine what should be defined as a high proportion.
The noble Lord, Lord Beecham, also asked about high levels of crime. Again, it is for local authorities to determine whether they consider their crime levels to be high in a particular area. However, he will know as well as I do that local authorities make assessments of low and high crime areas across each borough of a county, and they make determinations accordingly.
The noble Lord, Lord Beecham, also asked about migration, using the example of people from Sunderland going over to Newcastle. However, it could also be people from Newcastle going over to Sunderland. I do not know what that does for football supporters but I am sure that the rivalry will be sustained. Nevertheless, the term “migration” is also left undefined, so it would take on its ordinary meaning of referring to people moving into an area from neighbouring cities in different parts of the country, as the noble Lord himself suggested, or from overseas. It is worth saying that migration can have an important impact on the supply and demand of rented accommodation and may result in a shortage of available accommodation overall. A small number of rogue landlords are known to exploit such a scheme.
Although I fully accept that the noble Lord may have sought more precise definitions, the emphasis is that we seek to keep the definitions broad to allow local and, indeed, regional interpretation. We will provide further clarification in the guidance. The final sense that I would convey is one of understanding that these are new provisions and that it is important that we review the policy in practice. I am therefore pleased that the Government have committed to the 18-month review.
