Question Time: Can I back-claim Child Benefit? Change broadband before April? Why does my 7% regular saver only pay 4%?

Available for over a year

It's a geek editon of our Question Time podcast! This week Martin Lewis gives you answers on your questions asking him anything and everything, including: should I wait until April to change my broadband to avoid the price hikes? Can I back-claim child benefit, now I know I’m eligible? Why did my 7% regular saver pay me half of that in interest? If I have to buy credits to purchase a game, can I get a cash refund if it’s faulty? I have a disability, so I need others to drive me in my car, how do I get insurance? Plus, does Martin find the ‘Dead Ringers’ impression of him funny? You’ll have to listen to find out! If you want to ask Martin a question, you now can! His Question Time podcast lets you ask Martin absolutely anything and everything (within reason!) – so if you’ve always wanted to know if he’s got hay fever, which galaxy is his favourite, or have a very complicated question about your personal finances, email it to MartinLewisPodcast@bbc.co.uk.
