Nearly three-quarters of renters (71%) think their property could be more energy efficient – but 47% are unsure what changes they can make under their tenancy agreements.
A poll of 2,000 private tenants found that three in five (59%) feel frustrated by the fact that most of the information around making homes more energy efficient seems to be geared towards homeowners.
One in four think their property would benefit from an entirely new boiler being fitted, while 28% want better external wall insulation.
And a fifth would like double glazed windows installed, while 29% want solar panels put in.
More than one in ten (14%) say they have no idea how much their next energy bill will be.

As a result, 22% will be heading to the gym each morning for a shower to cut down on water and heating bills.
A quarter (26%) plan to bring their devices into the office to charge them up during the day.
Another 20% have their sights set on cafes to make use of their heating and Wi-Fi during workdays.
And 26% reckon it’ll be more cost effective to buy a few hot drinks, rather than heating their home.
Meanwhile, nearly a quarter (24%) of rental tenants will be spending more time in their local library this winter, so they don’t have to heat their homes.
And 23% will take the opportunity to visit friends and family members at their houses, while their own heating stays off.
More than a third (36%) believe these measures will help manage their outgoings this winter.
Smart Energy GB, which commissioned the OnePoll research, has produced an energy efficiency guide for renters to help them identify areas where they can take action.
Spokeswoman Victoria Bacon said: “With energy bills increasing, many people are making plans to beat the rising cost of living.
“But for renters, not knowing what energy efficiency changes they’re allowed to make can be an extra worry.

“Our guide covers low- or no-cost changes, like getting a smart meter, that are simple to do and effective at helping to keep your bills down.
“If you pay for the gas or electricity in your rented property, you can choose to have a smart meter. We recommend you tell your landlord before you get one.”
Property expert Kate Faulkner said: “Whether you’re looking to rent a new flat, or you’re looking to make improvements in your existing home, there are several simple steps you can take to help keep your energy bills down this winter.
“Understand how much energy you are using at what times by asking your energy supplier to fit a smart meter. Once you have one, this will make it much easier to focus on what's costing you the most.
“An easy way to cut your bills is to switch your bulbs to LEDs. If your property is difficult to keep warm, talk to your landlord about loft or cavity wall insulation, and turn your thermostat down by 1 degree.
“Your smart meter’s portable in-home display shows how much energy you’re using in pounds and pence, in near-real time.
“Your meter reading will also be sent to your energy supplier automatically, which means one less thing on your to-do list.”
