Automated switch to cheaper power tariff

[Someone]

Controlled load is limited to "approved" loads, and now requires permanent connections (no power points allowed). So you'd need an electrician to install it and you'd need to ask the supplier for approval. I'd say you've got Buckleys chance of getting a UPS on it, and even with the cheaper tarrif the costs of storage (battery wear etc) are unlikely to pay back.

I am not able to find any information on there being approved loads, in fact, I find quite the opposite:

Using off-peak times to reduce your electricity bills
There are many ways to save electricity with off-peak rates. You can save money by shifting your electricity use to off-peak times. Consider running appliances like dishwashers, washing machines and clothes dryers at off-peak times. Many appliances now have timers and delay start features; so you can control your electricity usage and save money.

I will give them a call today and see if they can give me a clear answer on this.

You're getting information for the consumer time of use (TOU) tariffs which don't have the changeover relay or separate meter but use time stamping from a smart meter to allow the retailer to provide arbitrary tariff structures. Compare the difference between the controlled load tariffs of 31 and 33:

Where they turn the power on and off to suit their supply/demand balance and will only let you install benign loads. Unlike the 22A general time of use which is a consistent connection which changes price by time of day.

How could they possibly know or find out if you implemented it. 

When they notice your drop is pulling huge amounts over overnight power and very little during the day and it doesnt match with their models, they know what the controlled loads are and have budgeted for their size. Also power abnormalities like that appear like a grow op, good times when your door gets kicked in by the police. Its stealing plain and simple, why not just run an extension cord from next door because they are on a cheaper tariff and also save on the daily supply charge?

Which is why this thread was about finding a legal way to do this, there is clearly no legal way and as such wont be done
