Energy bills tend to climb just as the nights draw in - and this winter is no exception. Ofgem's price cap rose 4% from 1 October 2026, taking a typical household's annual dual-fuel bill from £1,663 to £1,723. Here's how to keep costs down, and what's actually your landlord's responsibility rather than yours.
What's actually changed
Ofgem reviews the price cap every three months, and this latest increase reflects a rise in wholesale energy costs. It's worth noting the cap limits the price per unit of energy, not your total bill - so the more you use, the more you'll pay, cap or no cap.
Quick wins that make a real difference
Bleed radiators so they heat evenly and don't waste energy
Draught-proof windows and doors - even a simple draught excluder helps
Use thick curtains at night, and open them in the day to let heat in
Switch to a smart meter if you haven't already, to track usage in real time
Compare fixed tariffs - some currently sit £100 or more below the price cap
Who's responsible for what
Your landlord is responsible for keeping the heating system, boiler, and any fixed heating installations in safe working order. If something's broken, report it promptly - it's not something you're expected to fix or pay for yourself. What you can control day to day is usage: thermostat settings, how long the heating's on, and small efficiency habits around the home.
If you're struggling with bills
If energy costs are becoming genuinely difficult to manage, speak to your supplier directly - many offer payment plans or hardship support, and it's far better to raise it early than let arrears build up.
Frequently asked questions
Why did my energy bill go up in October?
Ofgem increased the energy price cap by 4% from 1 October 2026, reflecting higher wholesale energy costs - this applies to default tariffs across the market, not just one supplier.
Who pays to fix a broken boiler in a rental property?
Your landlord is responsible for maintaining and repairing the heating system and boiler - report any fault promptly through our maintenance platform.
Can I switch energy supplier in a rental property?
In most cases, yes - check your tenancy agreement, but tenants are generally free to choose their own energy supplier unless bills are included in the rent.
