How much does it take to freeze pipes?

The central heating system may well be okay, but the domestic hot and cold won't be protected by the water pumping around. If the ambient temp has been kept up though then you may be okay - depends where the pipes run and how well lagged they may be.

If the house is well insulated and double glazed I cant see internal temps reaching below freezing

The overflow pipe/condensation pipe seems to be the biggest problem around our area (-10 recently). They freeze up and the boiler can't fire up, or something like that.

Not had a problem myself though.

This is the problem.If the condensation outlet freezes it shuts down the system and it has to be manually restarted using the reset button.Obviously not being there you cant do that.It seems to be a bit of a design fault that a heating system is prone to failure when the weather gets very cold
Sounds like a Monty Python scetch,but all too real

Do it by text message. Like this It will keep the pipes warm in the big freeze and warm the water and house when you are heading up. Leave it off when you don't need it.

Some right ******** being said in this thread, but i would agree with if you are not going to be there for a while to drain the system, and shut off the cold water mains, and the gas,and electrics. what you have to do to turn it back on is simply fill it back up with water and turn on the gas and electric, how you fill it up depends on what boiler it is and weather it is a pressurised system or not.

Ps i have been to 6 properties today who had frozen pipes, even the main circulation pipes for the heating, not lagged though, .

Yep I agree Bfm, I've said the same in the pm I sent ralph a while ago.
It's a no brained IMO, minimises risk if the systems are drained.
