Setting Up Gas and Electricity for First-Time Buyers: Comparing Octopus Energy, British Gas, and EDF

Moving into your first home brings excitement and a long list of tasks, with setting up utilities often feeling like one of the most daunting. Between deciphering energy jargon, understanding different tariff types, and comparing countless providers, it's easy to feel overwhelmed. This guide cuts through the confusion to help you make informed decisions about your gas and electricity supply.

Understanding the Basics: Gas vs Electricity Contracts

In the UK, energy contracts typically fall into two main categories, each with distinct advantages depending on your circumstances and risk tolerance.

Fixed-rate tariffs lock in your unit rates and standing charges for a specified period, usually 12 to 24 months. This offers price stability, protecting you from market fluctuations during volatile periods. However, if energy prices decrease during your contract term, you might end up paying more than the current market rate.^[1]

Variable-rate tariffs, also known as Standard Variable Tariffs (SVTs), can change at any time, often following Ofgem's energy price cap adjustments. While they offer flexibility to benefit from price drops, they also expose you to unexpected increases.

How Off-Peak Electricity Tariffs Work

Off-peak electricity tariffs provide cheaper rates during periods of low demand, typically at night. The most common off-peak tariff in the UK is Economy 7, which offers seven hours of reduced-rate electricity, usually between midnight and 7am. Some suppliers also offer Economy 10 tariffs, providing ten hours of off-peak electricity across different time slots.^[2]

To benefit from these tariffs, you'll need a compatible meter. It's worth noting that the government discontinued radio teleswitch technology (RTT) in June 2025, meaning households with older Economy 7 meters that relied on RTT needed to switch to smart meters to continue using off-peak tariffs.^[2]

These tariffs work particularly well if you can shift energy-intensive activities like washing, dishwashing, or electric vehicle charging to off-peak hours. For example, Octopus Energy's "Octopus Go" tariff offers a low off-peak rate from 11:30pm to 5:30am, designed specifically for EV owners charging overnight.^[3]

Comparing Major UK Energy Suppliers

When evaluating energy suppliers for your new home, several key factors deserve consideration beyond just headline prices.

Tariff types vary significantly between suppliers. Some offer innovative time-of-use tariffs that can be advantageous if you can shift energy-intensive activities to cheaper periods.^[3]

Pricing structure requires careful comparison of both unit rates (cost per kilowatt-hour) and standing charges (daily fees). A lower unit rate with higher standing charge might suit high-usage households, while higher unit rates with lower standing charges could benefit those with modest consumption.^[4]

Customer service and reputation matter more than many first-time buyers realise. A supplier with excellent customer service makes managing your energy account significantly more straightforward, especially when issues arise.

Do Octopus Energy Do Gas?

Yes, Octopus Energy supplies both gas and electricity through dual fuel deals. They've built a reputation for innovative tariffs and strong customer service, making them a popular choice for tech-savvy consumers who appreciate their app-based account management.

Is EDF Energy Good for First-Time Buyers?

EDF Energy offers comprehensive dual fuel packages and has invested heavily in renewable energy infrastructure. Their tariffs include both standard and green energy options, appealing to environmentally conscious consumers. They also provide various payment methods and support options suitable for first-time buyers.

Octopus Energy vs British Gas

Both suppliers offer competitive dual fuel deals, but they appeal to different customer preferences. Octopus Energy tends to attract customers who value innovation and digital-first service, while British Gas offers more traditional customer service approaches and has extensive engineer networks for boiler servicing and repairs.

Essential Considerations for First-Time Buyers

As a first-time buyer, several specific factors deserve attention when choosing your energy supplier.

Assess your energy usage patterns. The average UK household uses approximately 3,900 kilowatt-hours (kWh) of electricity annually, but this varies significantly based on home size, occupant number, and appliance efficiency.^[5] Understanding how much electricity does a house use per day UK-wide can help you choose appropriate tariffs.

Check meter compatibility before committing to off-peak tariffs. Your home needs compatible metering equipment to access these cheaper rates, and upgrading might be necessary.

Review contract terms carefully, including contract lengths, exit fees, and introductory offers. Some attractive headline rates come with conditions that might not suit your circumstances.

Power rates comparison becomes crucial for long-term savings. Regular comparison can lead to significant reductions in your energy bills, and switching has become much simpler in recent years. Services like Join Lodo can handle the switching process for you, removing the paperwork and confusion that often deters people from seeking better deals.

Home Energy Save Tips for New Homeowners

Beyond choosing the right supplier, implementing energy-saving measures can substantially reduce your bills. Using energy-efficient appliances, improving home insulation, and utilising smart meters provide immediate and long-term benefits.

Smart meters offer real-time usage data, helping you identify energy-hungry appliances and adjust your habits accordingly. Most major suppliers install these free of charge.

Don't Forget Other Utilities

While focusing on gas and electricity, remember that broadband wifi setup requires separate consideration. Research local providers for the best coverage and deals in your area, as broadband quality varies significantly by location.
