Time-of-Use Tariffs vs Fixed-Rate Energy Deals: Which Saves You Money in 2026
The UK energy market has transformed dramatically over the past two years, with time-of-use tariffs shifting from niche products to mainstream options. If you're wondering whether these new pricing structures could slash your bills compared to traditional fixed-rate deals, you're not alone. With 835,000 households now on smart time-of-use tariffs and bundled broadband-energy packages becoming increasingly common, understanding these options has never been more important.
What Are Time-of-Use Tariffs and Why Are They Taking Off?
Time-of-use (TOU) tariffs charge different electricity rates depending on when you use power throughout the day. Instead of paying a flat rate, you'll typically pay less during off-peak hours (often midnight to 5am) and more during peak times when demand is highest.
The numbers tell a compelling story. Between April 2024 and July 2025, there was a 96% increase in homes on smart TOU tariffs, with 2.8% of UK households now registered[1]. The main driver? Electric vehicle tariffs, which account for 78% of TOU sign-ups, with EV tariff adoption growing by 120% since April 2024[1].
To access most basic TOU tariffs, such as Octopus Energy's Agile Octopus, you'll need a smart meter installed. Some tariffs may also require you to own an electric vehicle or heat pump[1].
The Real Savings Potential: What the Numbers Show
For households that can shift their energy usage patterns, the savings can be substantial. An average household with an electric vehicle could see their annual energy costs drop from £1,528 to £954 by shifting just 50% of electricity consumption to off-peak periods (midnight to 5am), saving £574 annually[1].
Even more impressive, maximizing off-peak usage could reduce costs to £381, resulting in £1,147 in annual savings[1]. However, these figures assume you can successfully time your energy-intensive activities, such as EV charging, dishwasher cycles, and washing machine use, to coincide with cheaper rates.
How Fixed-Rate Tariffs Stack Up in 2026
Fixed-rate tariffs lock in consistent per-unit pricing for a set period, offering budget certainty. However, they come with trade-offs. If market prices fall, those on fixed tariffs may end up paying more than customers on variable rates.
This timing consideration is particularly relevant now. UK energy prices are forecast to drop in 2026, with household energy bills expected to fall by approximately £150 annually from April due to government policy changes[2]. The energy price cap, currently at £1,758 for a typical dual-fuel household, is projected to decrease to £1,620 in Q2 2026[2].
Comparing Major Provider Tariffs
To help you evaluate your options, here's how the major providers' tariffs compare based on current 2026 rates:
| Provider | Tariff Type | Unit Rate (p/kWh) | Standing Charge (p/day) | Example Monthly Cost (kWh) | Annual Cost (£) |
|---|---|---|---|---|---|
| Click Energy | Fixed-Rate | 24.990 | 12.420 | 300 | £845 |
| Click Energy | Fixed-Rate | 26.935 | 10.219 | 300 | £899 |
| E.ON Next | Fixed-Rate | 27.4 | 34.7 | 300 | £867 |
| British Gas | Fixed-Rate | 28.1 | 47.1 | 300 | £1,027 |
| E.ON Next | Time-of-Use | 27.4 | 34.7 | 300 | £867 |
| British Gas | Time-of-Use | 28.1 | 47.1 | 300 | £1,027 |
The Rise of Bundled Broadband and Energy Deals
Another significant market development is the emergence of bundled broadband and energy packages. Several providers now offer combined deals that can deliver both cost savings and administrative simplicity.
Octopus Energy, for example, offers bundle discounts ranging from £3 to £5 monthly when customers combine broadband and energy services[3]. While this might seem modest, it accumulates to £36-£60 annually, plus the convenience of unified billing. For those exploring broadband deals in Reading, York, Norwich, or other areas, these bundled options are worth considering alongside standalone broadband packages.
The concept extends beyond traditional energy providers too. Some customers considering switching from Vodafone to Voxi for mobile services are also exploring whether bundled home services from the same provider group offer additional value.
Evaluating Whether TOU Tariffs Work for Your Household
The key question isn't whether time-of-use tariffs can save money in theory, but whether they'll work for your specific circumstances. Here's how to assess your situation:
Analyze Your Energy Usage Patterns
Look at when you currently use the most electricity. If you're already running appliances, charging devices, or heating water during typical off-peak hours, you're well-positioned to benefit. Smart meter data can help you identify these patterns more precisely.
Consider Your Flexibility
Can you realistically shift energy-intensive activities to off-peak times? This might mean setting timers on appliances, charging your EV overnight, or using storage heaters more strategically. The more flexible you can be, the greater your potential savings.
Factor in Gas vs Electricity Costs
Remember that time-of-use tariffs primarily affect electricity pricing. Gas prices generally remain more stable throughout the day. If your household is gas-heavy for heating and cooking, the impact of TOU electricity pricing may be less significant.
Making the Switch: Practical Next Steps
If you've determined that a time-of-use tariff or bundled deal could work for your household, the switching process has become much simpler than in previous years. Many providers now offer streamlined online switching, though managing multiple comparisons and paperwork can still be time-consuming.
Services like Join Lodo can handle the entire switching process for you, from comparing tariff structures across providers to managing the administrative details. This can be particularly helpful when evaluating complex TOU tariffs alongside traditional fixed-rate options and potential bundle deals.
Timing Your Switch
Given the projected energy price decreases in Q2 2026, timing matters. If you're currently on an expensive fixed-rate deal, switching sooner rather than later could capture immediate savings. However, if you're on a competitive rate, waiting until closer to the projected price cap reduction might be wise.
Let Lodo Handle the Switch for You
Comparing time-of-use tariffs against fixed rates while factoring in your specific usage patterns can be complex. Lodo specializes in navigating these nuanced tariff structures and can quickly identify whether a TOU deal or traditional fixed rate offers better value for your household.
Rather than spending hours comparing providers and filling out switching forms, simply tell Lodo what you need via chat or WhatsApp. It handles everything from finding the optimal tariff match to managing the paperwork and confirming your switch, turning what could be a lengthy process into a few minutes of conversation.

Frequently Asked Questions
What are time-of-use tariffs and how do they differ from traditional fixed-rate energy deals?
Time-of-use tariffs charge different rates for electricity based on the time of day, encouraging usage during off-peak hours. In contrast, fixed-rate energy deals lock in a set price per unit of energy for a specified period, providing price stability.
How can I determine if a time-of-use tariff will reduce my energy bills?
To assess potential savings, analyze your household's energy consumption patterns and compare them against the off-peak and peak rates of available time-of-use tariffs. Tools like smart meters can help track usage and identify optimal times for energy-intensive activities.
What are the benefits of bundling broadband and energy services?
Bundling broadband and energy services can lead to cost savings, simplified billing, and potential discounts. Providers like Virgin Media offer packages combining high-speed broadband with TV services, while EE provides broadband deals with added benefits.
Are there any current broadband deals in Reading, York, or Norwich?
Yes, providers such as EE and Virgin Media offer broadband deals in these areas. For instance, EE has a 150Mbps Full Fibre package available in Reading, York, and Norwich, with prices starting at £27.99 per month.
How do time-of-use tariffs impact gas and electricity costs?
Time-of-use tariffs can lead to savings on electricity bills by incentivizing off-peak usage, but they may result in higher costs during peak times. Gas prices are generally lower than electricity prices, but this can vary based on market conditions.
