Navigating energy in your first home

The dream of owning your first home shouldn't be overshadowed by worries about energy bills. Instead, smart energy management can transform your new property into an efficient, comfortable haven.

The initial energy landscape

When you first move into a property, you automatically inherit the existing energy supplier on what is known as a "deemed contract"1. This often means you will be on their Standard Variable Tariff, which can be among the more expensive options available. Understanding this initial setup is your first step towards taking control. You will need to locate your gas and electricity meters, take initial readings, and identify who your current suppliers are. This can usually be done by asking the previous owner or estate agent, or by using national databases if that information is not readily available.

Beyond the purchase: your energy journey

Your energy journey does not end with identifying your supplier. It is about proactively managing your consumption and costs. The future should be one of energy abundance, not scarcity, enabling comfort and convenience in your new home without guilt. Smart technology and transparent data empower you to control your energy consumption effectively, fostering a sense of control over household costs.

Understanding your energy setup and tariffs

Deciphering your energy bills and choosing the right tariff can seem daunting, but it is a critical step in managing your new home's running costs.

Identifying your current supplier

Upon moving in, one of your first tasks is to find out who supplies your gas and electricity. Take a photo of your meter readings on moving-in day to mark the start of your responsibility. If the previous owner or estate agent has not provided details, you can use national databases to identify the suppliers for your address. Once identified, contact them to set up your account and provide your opening meter readings.

Deciphering energy tariffs

An energy tariff is essentially the pricing structure for your gas and electricity. Most tariffs consist of two main charges:

• Unit rate: This is the price you pay for each unit of energy you use, measured in kilowatt-hours (kWh).
• Standing charge: A fixed daily fee that covers the cost of being connected to the energy network, regardless of how much energy you use. All tariff rates, including unit rates and standing charges, are quoted inclusive of VAT at 5%.

There are two primary types of tariffs:

• Fixed-rate tariffs: The unit rate and standing charge remain constant for a set period, typically 12 or 24 months. This offers predictability for budgeting but may incur exit fees if you switch before the contract ends.
• Variable-rate tariffs: The unit rate and standing charge can fluctuate based on market prices, often reviewed quarterly. Standard variable tariffs are often the default and can be more expensive, but typically have no exit fees. Variable tariffs are updated quarterly on 1 January, 1 April, 1 July, and 1 October.

Understanding these differences allows you to choose a tariff that best suits your usage patterns and financial planning. If you are on a fixed-rate tariff and leave early, an exit fee of £50 typically applies, unless you are within the first 14 days (cooling-off period) or the last 49 days of your contract.

The power of smart meters for first-time buyers

Smart meters are a game-changer for new homeowners, offering unparalleled insight and control over energy usage.

Why smart meters matter

Smart meters enable automated readings, eliminating the need for manual submissions and ensuring accurate bills based on your actual consumption, not estimates. More importantly, they provide real-time data on your energy usage, often displayed on an in-home display (IHD). This transparency allows you to see how much energy you are using and what it is costing you, helping you identify energy-saving habits and make smarter choices around the home. While a smart meter will not directly reduce the amount of energy you use, it significantly increases your awareness, which in turn encourages more efficient behaviour. They are also essential for accessing certain specialised tariffs, such as those designed for electric vehicle (EV) charging. While not always essential for export tariffs, smart meters can enhance the management of exported energy.

Getting a smart meter installed

If your new home does not already have one, smart meters are installed free of charge by your energy supplier upon request. This applies to customers who join Fuse Energy with a manual (non-smart) meter, who are eligible for a free smart meter upgrade once their supply has switched in. The installation process is straightforward, and your supplier will arrange a convenient time for an engineer to visit. Once installed, your smart meter will automatically send readings to your supplier, bringing an end to estimated bills and giving you immediate access to your energy data.

Making your first home energy efficient

Improving your home's energy efficiency does not have to mean sacrificing comfort. It is about making smart choices that lead to a more comfortable, affordable, and abundant energy future.

Simple upgrades for immediate impact

Even small changes can make a big difference to your energy consumption. Consider these quick, cost-effective upgrades:

• Switch to LED lighting: Light-emitting diode (LED) bulbs use significantly less electricity and last longer than traditional bulbs.
• Draught-proofing: Seal gaps around windows, doors, and even floorboards to prevent heat loss. Simple draught excluders and weatherstripping can be very effective.
• Optimise heating controls: Learn how to use your thermostat and radiator valves effectively to heat only the rooms you need, when you need them. Setting your hot water temperature to around 60°C is also a good practice.
• Thermal curtains and blinds: Heavy curtains can help insulate windows, reducing heat loss in winter and keeping rooms cooler in summer.

These simple steps can quickly contribute to a more energy-efficient home and noticeable savings on your bills.

Long-term efficiency investments

For those looking to make a more significant impact, consider these long-term investments:

• Insulation: Upgrading loft and wall insulation is one of the most effective ways to reduce heat loss, keeping your home warmer in winter and cooler in summer. A well-insulated loft should have around 300mm of insulation.
• Double or triple glazing: Replacing old, inefficient windows can drastically improve your home's thermal performance.
• Energy-efficient doors: Just like windows, old external doors can be a significant source of heat loss. Upgrading to insulated doors helps maintain indoor temperatures.
• Solar panels: While a larger investment, solar panels allow you to generate your own electricity, reducing reliance on the grid and potentially earning money by selling surplus energy back. Investing in solar panels can even lead to zero bill homes for some. For those considering an electric vehicle, understanding the right home EV charger is key.

Remember, the Energy Performance Certificate (EPC) rating of your home significantly impacts its energy costs, so improvements in these areas can lead to substantial long-term benefits. An EPC provides a rating from A (most efficient) to G (least efficient) and includes recommendations for improvements.
