Sustainable living for renters (without renovating)

Renters face a real structural disadvantage when it comes to home energy efficiency. The people who pay the bills aren't the people who decide the insulation. This guide focuses on what you can actually do — and how to make the case for what only your landlord can fix.

The renter's challenge

Renters live with a genuine structural problem. The homes available to rent are often older, less insulated, and less energy-efficient than owner-occupied housing, because landlords who don't pay the energy bills have less direct incentive to invest in efficiency. Meanwhile, tenants who do pay the bills have no power to change the building fabric.

This isn't a personal failing. It's a systemic issue that policies in many countries are slowly beginning to address — minimum energy efficiency standards for rental properties exist in some regions, with more being developed. Rights vary significantly depending on where you live, so it's worth checking what applies to your situation locally.

The good news is that even within these constraints, there is a meaningful amount you can do:

• Habits and behaviours that don't require any changes to the property at all.
• Removable additions — thermal curtains, draught excluders, rugs — that make a real difference to comfort and bills.
• A constructive conversation with your landlord about improvements that benefit both of you.
• Choices about energy tariffs, water, food and purchasing that apply regardless of whether you own or rent.

Energy and heat without renovation

You can't insulate the walls or replace the boiler. But you can significantly reduce heat loss and energy use through things that are entirely within your control.

• Draught excluders on doors. A foam or fabric draught excluder at the bottom of an external door or a cold internal door is one of the most effective and inexpensive things you can do in a poorly sealed home. It's removable, takes minutes to fit, and can noticeably reduce draughts. A rolled towel does the same job temporarily.
• Removable weatherstripping on windows. Self-adhesive foam tape applied around window frames seals small gaps and is inexpensive. It can be peeled away when you leave. For older sash windows that rattle, secondary glazing film — stretched over the frame and applied with double-sided tape — reduces heat loss significantly and is fully reversible.
• Thermal curtains. Heavy or lined curtains at windows dramatically reduce heat lost through glass, especially at night and in winter. Bought secondhand, they cost very little. Close them at dusk and the difference is noticeable in rooms with poor glazing. You take them with you when you move.
• Rugs on cold floors. In properties with uninsulated solid floors, a rug provides a genuine thermal barrier underfoot and makes rooms feel significantly warmer without any heating adjustment.
• LED bulbs. If your rental has older bulbs, switching to LEDs is cheap, immediate, and dramatically reduces energy use for lighting. Buy them, take them with you when you go, and replace the originals in the light fittings before moving out.
• Smart plugs and timers. A smart plug with a timer controls heating or appliances on a schedule, even if you can't modify the thermostat or boiler controls. These are portable and easy to set up.
• Switch off standby. Televisions, laptops, games consoles and chargers draw power continuously when left on standby. A switched power strip turns off a whole cluster of devices at once with a single button.
• Switch your energy tariff. In many countries, tenants who pay their own energy bills can choose their supplier and tariff, including switching to a green energy provider. This doesn't require landlord permission, takes about ten minutes, and ensures the electricity you use is matched with renewable generation. Rules vary by country — check what's available where you are.

For a full breakdown of energy-saving habits and upgrades, our guide to saving energy at home covers what applies to rented properties as well as owned ones.

Talking to your landlord about efficiency upgrades

Improvements to a property's energy efficiency — insulation, double glazing, an efficient boiler — are the landlord's responsibility and investment. That doesn't mean you can't raise them. Many landlords are more receptive than tenants expect, particularly when the conversation is framed well.

How to frame the conversation:

• Focus on mutual benefit. Better insulation and an efficient heating system mean lower energy bills for you and a more lettable, more valuable property for the landlord. High energy bills make a property less attractive to future tenants. A better energy rating can also be a marketing point in competitive rental markets.
• Be specific. Rather than a general request for "improvements," identify specific issues: "the kitchen window has a significant gap and cold air comes in — could you seal it?" or "the hot water tank doesn't appear to have an insulation jacket" is more actionable than a vague request.
• Put it in writing. Email or message is better than a verbal conversation — it creates a record. Keep the tone constructive and practical.
• Reference local regulations if applicable. Many countries and regions now have minimum energy efficiency standards for rental properties, and some have deadlines for landlords to reach them. If your property falls below the required standard, your landlord may already be legally obliged to improve it. Look up what applies in your area — this varies significantly by country.
• Offer to manage small things yourself. For minor draught-proofing or low-cost improvements, some landlords are happy for tenants to do it themselves with the landlord covering the cost of materials. Offering this can make it easier for the landlord to say yes.

Not every landlord will respond positively, and your rights and remedies if they don't vary by location. Understanding your local tenancy rights is worth doing regardless of your specific situation.

Water saving without plumbing changes

Water efficiency is an area where habits and small additions make a real difference without any modification to the property's plumbing.

• Shorter showers. Heating water is one of the most energy-intensive things in a home. Keeping showers to four or five minutes uses significantly less hot water than eight or ten minutes. If your shower also heats water on demand (rather than from a tank), shorter showers save both water and energy immediately.
• Turn taps off when not actively using them. Running taps while brushing teeth or rinsing dishes between scrubs wastes a surprising amount of water over time.
• Report and fix dripping taps promptly. A persistent drip from a tap is the landlord's responsibility to fix — report it in writing. If ignored and the drip is genuinely significant, follow up with a reminder that unaddressed leaks can cause damage to the property.
• Low-flow shower head aerators. Some low-flow showerheads simply screw on in place of the existing one and can be unscrewed and taken with you when you move. Check whether your shower fitting is compatible before buying. These reduce water flow without significantly affecting the shower experience.
• Full loads only. Run dishwashers and washing machines only when full, and use eco settings where available. These are habit changes with no cost.

Our guide to saving water at home covers room-by-room habits across the whole house.

Waste, recycling and composting in rentals and apartments

Waste management in rented properties — particularly flats and apartments — can be more complicated than in houses with private bins. The setup varies enormously by building, by landlord, and by local authority.

• Find out what your local authority actually collects. Recycling systems differ significantly between areas. A quick check of your council or municipality's website tells you exactly what goes in which bin or bag. If your building has communal bins, check the labels and ask the building manager if you're unsure.
• Ask for better provision if it's missing. If your building doesn't have recycling facilities or separate food waste collection, raising this with your landlord or building management is reasonable. It's also worth checking with your local authority whether they can provide additional bins or bags for communal properties.
• Composting without a garden. A countertop food waste caddy collects scraps from cooking — vegetable peelings, fruit ends, coffee grounds, eggshells — until they can be disposed of. Options for what to do with them include: your local council's food waste collection service (check if this covers flats in your area), a community composting scheme or allotment that accepts organic matter, a bokashi bin that ferments food scraps (including cooked food and meat) into a soil amendment, or a compact worm bin, which can live under a sink or in a corner and requires minimal space.
• Reduce what you're throwing away. Packaging waste is minimised by buying fewer packaged products, choosing packaging that can be recycled in your area, and buying in bulk where that makes sense for your household.

Furnish secondhand and take it with you

For renters who need to furnish their own home, secondhand is the clear first choice — both for sustainability and for cost. Good furniture bought secondhand costs a fraction of new, can be taken to future properties, and carries a much lower environmental footprint than new production.

• Check what's already there. Furnished and part-furnished rentals often include more than the listing describes. Before buying anything, check every cupboard and storage space — landlord furniture is sometimes stored on-site.
• Source from local marketplaces first. Online local selling groups, Freecycle, Gumtree, eBay and Facebook Marketplace all have furniture at every price point. Charity shops in residential areas often have a furniture section. End-of-year student sales are particularly good for cheap kitchen equipment and small furniture.
• Buy portable, not built-in. In a rental, freestanding furniture is almost always better than anything that requires fixing to walls or floors. Freestanding shelving, standalone wardrobes and modular storage can be reconfigured or taken to a new home. Built-in solutions often can't be removed cleanly.
• Invest in quality secondhand for core pieces. A good secondhand sofa, bed frame or desk bought at full charity-shop price still costs far less than new — and a durable item will outlast several moves.
• Take it with you. One of the advantages of owning your own furniture — even secondhand — is that you take it when you leave rather than furnishing from scratch each time. This reduces waste and cost across multiple moves.

Our secondhand buying guide covers where to look and how to buy well across furniture, clothing, electronics and more.

Reversible improvements only — and know your rights

As a renter, the principle to apply to any physical change to the property is: can it be fully reversed before I leave, leaving no trace? If yes, you can usually do it without asking. If no, ask first.

• Things that are always fine without permission: draught excluders (freestanding), removable self-adhesive weatherstripping, thermal curtains on existing curtain rails, LED bulbs (replacing originals when you leave), rugs, smart plugs, switching energy tariffs (where you pay the bill), and all habit-based changes.
• Things to ask about first: fitting new curtain rails or additional hooks, painting walls, adding picture rails or shelving that requires drilling, or any change to fixtures and fittings.
• Things that are the landlord's responsibility: structural draught-proofing, insulation, replacing inefficient appliances, window and door repairs, and addressing damp. These should be requested formally in writing.
• Know that rights vary by country and region. Tenants' rights around energy efficiency, deposit protection, permitted improvements and landlord obligations differ significantly depending on where you live. What's standard practice in one country may not apply at all in another. Look up the specific rules in your area rather than relying on general assumptions.

Renter's sustainability checklist

• Add a draught excluder to the coldest external door.
• Hang thermal curtains on windows, especially north-facing ones.
• Switch all bulbs you can reach to LEDs; bag the originals to reinstall when you leave.
• Put your TV and devices on a switched power strip to kill standby.
• Check your energy tariff — switch to a green supplier if available in your country.
• Find out what your local authority collects and set up correct sorting in your kitchen.
• Set up a countertop food waste bin and find somewhere to take the scraps.
• Raise one specific energy efficiency issue with your landlord in writing.
• Buy your next piece of furniture secondhand rather than new.
