Most energy efficiency content assumes you own your home. Solar panels, heat pumps, loft insulation, new double glazing — all sensible suggestions if you can drill holes in walls and make structural decisions. If you’re renting, you can’t do any of that. You’re also the one paying the bills.
Around 4.6 million households in England rent privately. For most of them, the conversation about energy efficiency has to start somewhere different. Here’s what actually moves the needle when you’re a tenant.
Know What Your Landlord Is Legally Required to Do
This matters before anything else. Since April 2020, private landlords in England and Wales cannot legally let a property with an EPC rating below E. Since April 2023, they cannot continue letting a property with a rating below E without an exemption. A proposal to raise this to C by 2028 is working its way through policy — but the current floor is E.
If your property has an EPC rating of F or G, your landlord is legally required to bring it up to at least E, up to a spend cap of £3,500. You can check your property’s EPC on the government’s register at gov.uk/find-energy-certificate. If the rating is below E and your landlord isn’t acting, you can report this to your local council’s environmental health team.
An EPC rating below E often means inadequate insulation, an inefficient heating system, or single glazing — all things that directly affect your bills. Knowing your rights here is the first lever to pull.
Switch Your Energy Tariff (You Can Do This as a Tenant)
Unless your tenancy agreement specifies otherwise, you can typically switch energy suppliers as a tenant — you just can’t make structural changes to the property. Check your tenancy agreement first, but most give tenants the right to choose their own supplier.
With the Ofgem price cap currently setting the ceiling on standard variable tariffs, the main opportunity is in time-of-use tariffs if you have a smart meter. Octopus Agile and similar products let you shift usage to overnight hours when wholesale prices are lowest — typically midnight to 6am. If you do laundry, run the dishwasher, or charge an EV overnight, this can cut the cost of those loads substantially.
You’ll need a smart meter for time-of-use tariffs. You can request one from your current supplier — they’re free to install and your landlord cannot block this. It doesn’t affect the property structurally.
Energy Monitors: Understand Where Your Money Is Going
A clamp-on energy monitor costs £30–60 and clips onto your electricity meter without any installation. It shows you real-time consumption in kilowatts and cost per hour. This is surprisingly useful for identifying devices you didn’t realise were expensive.
Common discoveries: old electric storage heaters running on high settings when not needed, fridges or freezers that are inefficient because the seals have gone, gaming PCs or monitors left on standby but still drawing significant power, and tumble dryers that cost far more per load than expected.
Once you can see actual cost, the decisions become obvious. Clamp-on monitors from Efergy, Sense, and similar manufacturers need no permission and leave no marks.
Smart Plugs for Control and Scheduling
Smart plugs (£10–20 each, more for energy-monitoring versions) let you schedule devices, check their consumption remotely, and cut power to devices on standby. The energy-monitoring versions — Kasa, TP-Link, Meross — show you per-device consumption and often let you set schedules based on time-of-use tariff windows.
Practical uses: scheduling the kettle, turning off entertainment systems that draw standby power, ensuring electric heaters don’t run when you’re at work, and automating overnight charging of phones and laptops during cheaper rate periods.
Portable Electric Heaters: Zonal Heating That Works
Heating is usually the biggest component of a renter’s energy bill, and most rented properties have central heating systems you can’t replace or upgrade. What you can do is reduce how much you use the central heating by supplementing with zonal electric heating in the rooms you actually use.
Modern oil-filled radiators and panel heaters are not the inefficient space heaters of the past. Units with programmable thermostats and timers can heat a bedroom for the two hours before you go to sleep and turn themselves off, rather than heating the whole flat all evening. The economics depend on your tariff and how inefficient your central heating is, but in a poorly insulated flat with an old boiler, targeted electric heating in occupied rooms can cost less than running the whole system.
Infrared panel heaters go a step further — they heat objects and people rather than air, which means rooms feel warmer faster and less heat is lost through ventilation. They require no installation and can be wall-mounted temporarily or floor-standing.
Draught Exclusion: Small, Cheap, and Effective
Draught exclusion is entirely reversible and requires no permission. Under-door draught excluders, secondary glazing film (the stick-on film that creates an air gap in front of existing windows), and letterbox covers are all available from hardware stores for under £20 and can be removed without damaging the property.
In older properties with single glazing or gaps around window frames, draught-proofing can make a noticeable difference to comfort, which often means you turn the heating down. The secondary glazing films are particularly effective — an A4-sized air gap in front of single glazing can roughly double its thermal performance.
What You Can Legitimately Ask For
Under the Minimum Energy Efficiency Standards regulations, your landlord must carry out improvements that can be funded through available grants before spending their own money on the cap. This means the Eco4 scheme — the government’s main energy efficiency grant for low-income and vulnerable households — can fund insulation or heating upgrades in privately rented properties without costing the landlord anything, in many cases.
If you’re on Universal Credit, certain other benefits, or have a household income under a threshold, it’s worth checking eligibility for Eco4 and raising it with your landlord. Landlords who refuse to apply for free grant funding they’re eligible for are in a weaker position than they might assume.
The Practical Starting List
If you want to act immediately without involving your landlord at all:
- Check your EPC rating — know where you stand legally
- Request a free smart meter from your supplier
- Compare time-of-use tariffs once you have a smart meter
- Buy a clamp-on energy monitor and spend a week understanding your consumption
- Add smart plugs to your highest-consuming portable devices
- Seal draught gaps with stick-on excluders and secondary glazing film
None of this requires permission. None of it damages property. And the combination — particularly tariff optimisation alongside consumption awareness — typically cuts a typical renter’s electricity bill by 15–25% without any lifestyle change beyond a bit of scheduling.
