Q I live in a rented terraced house with old, ill-fitting sash windows. Could you suggest how to insulate them without breaking the bank? The ideal solution would be to replace all the windows and fit them with double glazing, but the landlord will never accept such an expensive job.

A You have some classic thermal issues too costly to remedy for your tenancy, so in the short term think about the following to warm up your home and reduce your heating bills and carbon footprint. During the winter months, fit temporary double glazing. This can either be a polythene sheet that is adhered to the window frame and tensioned with a hair dryer, or a cut-to-size acrylic plastic sheet that is screwed to the frame. Fit thick curtains over the windows - think ready-made vintage from markets or second-hand shops, and make it stylish, too! Fit silver reflecting panels behind the radiators to kick the heat forward into the room, and cut draughts from doors and windows with foam or copper strips (try www.homebase.co.uk).

Q I live in a two-bedroom flat with a friend, and space is at a premium. My son (who stays once a month for the weekend) is now ready for his first bed. He sleeps in my room, so can you recommend a bed (not a Z-bed) that converts into a chair/sofa when he isn't staying with me?

A Check out the range of brilliant AeroBed inflatable mattresses. I've got one for guests: it pops up in seconds with its built-in motor and is as firm as a conventional mattress. Deflated, it can be folded into a bag and neatly stored away. Prices for single beds start from £50, so this makes it a space-saving budget choice (go to www.aerobed.co.uk). For the sophisticated option, take a look at the Dizzy range of fold-out single beds at www.johnlewis.com. Have it covered in warm brown leather, and no one will know that it's a bed by night. Prices range from £295 for fabric, up to £595 in leather.
