Why are my sockets / electrical outlets not working in one room?

If the sockets are not working in just one room it could be that room is on its own MCB and that might of tripped (kitchens are usually on their own MCB for example) If it has tripped, It could of been caused through a faulty appliance or wiring fault but that would likely trip the RCD aswell. Sockets not working could also be caused by break somewhere is the wiring whether it's been wired in a ring final, or radial circuit. There could be a faulty junction box somewhere that's causing the problem.

Do I need to undertake an electrical safety check before buying a house?

There is no law that's says you have to undertake an electrical safety check before buying a house, but you can't go wrong with having an eicr done first. I've tested many properties where the owner has had everything plastered, decorated and new kitchen fitted and then I find a fault somewhere or even worse the property needs a rewire. So having a safety check first can save you a lot of money and headaches down the line.

What are the benefits / advantages of installing CCTV?

One of the main benefits of installing CCTV is it acts as a great deterrent to criminals. It also gives the home owner a piece of mind knowing their property is being monitored at all times. And if the worst happens and there is any criminal damage to their property, they will have the evidence recorded by the CCTV.
