Staying Warm

As well as the tips featured in our Money Saving Calculator, you might also want to consider the following:

Heating (to warm up your rooms)

✔️ DO:

  • If you have a heat pump, set it between 18 and 22°C and keep it regularly maintained.

  • Place thermostats away from heat sources and open doors.

  • If you're using a wood burner, only burn dry, untreated and unpainted wood less than 11cm in diameter.

  • Keep all items – especially potentially flammable ones – at least one metre away from heaters and fires.

  • Plug electric heaters directly into a power socket rather than using a multiboard, to prevent overloading.

  • Use electric blankets safely and not with a hot water bottle. If you can, limit their use to save on power.

  • Close doors to keep the heat in.

❌ DON'T:

  • Leave any type of heater running while you're not in the room (except for heat pumps with a timer set).

  • Use an open oven door as a heater.

  • Use unflued gas heaters. If you have to use one, only do so for a short period (and never in small rooms) and keep a window and internal doors open for good ventilation.
    See WorkSafe's guidance or email [email protected] for advice.

Insulation (to keep the heat in)

✔️ DO:

  • Make sure your home is well insulated (in most cases, rental homes must be insulated by law).

  • Look into double or secondary glazing, or buy a window film insulation kit from a hardware store or supplier.

  • Tighten any loose door hinges to make sure doors fit snugly into their frames.

  • Block off any unused chimneys with a rubbish bag filled with shredded newspaper (make it obvious it's blocked, so nobody tries to light a fire) and secure your ceiling hatch, if there is one.

  • Use rugs and carpets where underfloor insulation isn't possible.

  • Keep the outside of your home sealed and painted.

❌ DON'T:

  • Touch foil insulation, which has been banned in residential buildings since 2016 due to the risk of electric shock.

  • Touch asbestos-containing insulation, which may be present in homes built or renovated before the year 2000.
    See WorkSafe's guidance or email [email protected] for advice.

Ventilation (to reduce moisture)

A dry home is easier and cheaper to heat.

✔️ DO:

  • Open windows once or twice a day for around 10-15 minutes if you can, or use a ventilation system.

  • Wipe away condensation from windows and walls.

  • Hang washing outside to dry if you can. If you're using a dryer with no exhaust vent, turn on an extractor fan or open a window. Do the same while showering, or install a shower dome to stop steam escaping.

  • While cooking, use the rangehood or extractor fan (or open a window) and use pan lids to keep the steam in.

  • Move furniture away from walls and leave wardrobes slightly open to discourage mould.

  • Use a dehumidifier, but only on damp days as they aren't a long-term solution and can be expensive to run.

  • Look into getting a ground moisture barrier installed, or ask your landlord about this.
