Why Are Home Energy Prices Going Up When Wholesale Prices Are Coming Down?
If wholesale gas and electricity prices are falling, why do so many households in the UK still feel like their energy bills are going up or barely changing? Here’s what’s really happening — and what you can do about it.
Understanding the Confusion Around Energy Prices
News headlines often talk about wholesale prices — the price suppliers pay to buy gas and electricity on the energy markets. But what you pay at home is a retail price, made up of many different parts. When wholesale prices move down, that does not automatically mean your home bill will drop straight away.
Over the last few years, UK households have seen:
- Record highs in gas and electricity prices after global energy shocks
- Government support schemes starting and then ending
- Changes to the Ofgem price cap every three months
- Standing charges rising sharply in many regions
So even when wholesale prices fall from those peaks, typical bills can still feel painfully high — and in some cases, they can even go up again.
Key point
Your bill is affected by much more than wholesale prices. Network costs, standing charges, green levies, supplier costs and government policy all play a part.
What Actually Makes Up Your Home Energy Bill?
Every time you receive a gas or electricity bill, you are not just paying for the energy itself. A typical UK household bill is made up of several components:
1. Wholesale energy costs
This is the price energy suppliers pay for gas and electricity on the wholesale market. It does eventually feed into your tariff, but with a delay and not pound-for-pound.
2. Network and system costs
These are the costs of transporting energy to your home (through pipes and cables), maintaining the network and balancing the national grid.
3. Operating costs & supplier margins
Suppliers must pay for customer service, billing systems, metering, IT, credit losses (customers who can’t pay), and a small profit margin.
4. Policy and environmental costs
These include support for renewable energy, energy efficiency schemes and social obligations which are currently built into bills.
5. VAT
Most households pay 5% VAT on their domestic gas and electricity.
6. Standing charges
A fixed daily fee you pay just to stay connected to the gas and electricity networks — regardless of how much energy you actually use.
How the Ofgem Price Cap Affects Your Home Energy Costs
The Ofgem price cap is one of the biggest reasons your bills don’t instantly mirror wholesale price changes. The price cap:
- Limits the unit rate (price per kWh) and standing charge suppliers can charge on standard variable tariffs
- Is updated every three months, based on forecasts and past wholesale prices
- Applies to most households not on a fixed deal or special tariff
This means:
- When wholesale prices surged, the cap went up in steps rather than overnight
- When wholesale prices drop, the cap also comes down, but usually with a delay and sometimes by less than people expect
- Other rising costs (like network charges or supplier costs) can push parts of the cap up even when wholesale costs are trending down
Why your bill can increase even as the cap falls
If you used more energy (for example, during a cold winter), ended a fixed tariff, or lost government support, your actual monthly payment can go up despite a lower price cap headline.
Why Are Standing Charges Going Up?
One of the most frustrating parts of recent bill changes has been the rise in standing charges. This fixed daily amount can now be higher than many households’ actual usage cost on mild days.
Reasons standing charges have risen
- Network maintenance and upgrades: Keeping the electricity and gas networks safe, modern and reliable is becoming more expensive.
- Supplier failures: When many smaller suppliers went bust, the cost of moving their customers and unpaid obligations was spread across bills.
- Social and policy costs: Some support schemes and protections are loaded into the fixed part of your bill.
The result is that you could see:
- Your unit rate per kWh coming down, but
- Your standing charge going up enough that your overall bill doesn’t feel much lower at all
Other Reasons Your Home Bills May Be Rising
Even with lower wholesale prices, several personal and structural factors can push your bills up:
1. End of fixed deals and discounts
If you were on a fixed tariff that expired, you may have been moved onto a standard variable tariff at price cap rates, which can be higher than your old deal, even if wholesale prices have eased.
2. End of government support schemes
During the energy crisis, various schemes (like the Energy Bill Support Scheme) reduced monthly costs. When these ended, bills rose, even if underlying prices were gradually falling.
3. Changes in your usage
Colder winters, working from home more, new appliances or an extra person in the household can all increase usage, offsetting any savings from falling unit prices.
4. Debt repayment and payment plans
If you are repaying energy debt through your bill, or if your supplier increased your direct debit to cover past underpayments, your monthly outgoing can rise even if prices per kWh go down.
5. Regional differences
Network costs vary by region, so households in some parts of the UK see higher standing charges or unit rates than others, regardless of national wholesale price trends.
6. Prepayment meter costs
Although progress has been made in equalising costs, households on prepayment meters historically paid more and can still experience different cost structures or top-up behaviours that raise effective bills.
Fixed vs Variable Tariffs: Should You Lock In Now?
One of the biggest decisions for UK households is whether to stay on a standard variable tariff (usually capped by Ofgem) or switch to a fixed tariff.
Standard variable (price-capped) tariffs
- Move up and down with the Ofgem price cap
- Offer flexibility — usually no exit fees
- Can benefit if prices fall further in future
- But you’re exposed if prices spike again between cap reviews
Fixed tariffs
- Lock in a unit rate and standing charge for 12–24 months
- Give certainty over the price you pay per unit
- May be slightly higher than the current cap but could protect you if prices rise
- Often come with exit fees if you switch again before the end
Tip: If you see a fixed tariff that offers real savings versus your current cap-based tariff, and you value certainty, it can be worth considering — especially if expert forecasts suggest the price cap could rise again.
How to Read Your Bill and Check If You’re Overpaying
Understanding your bill is the first step to taking control. On your latest gas or electricity statement, look for:
- Your tariff name – e.g. “Standard Variable”, “Flexible Saver”, or a named fixed plan
- Unit rate – price per kWh for electricity and/or gas
- Standing charge – the daily fixed charge
- Period covered – so you can compare usage across similar time frames
- Estimated vs actual readings – estimates can be inaccurate, especially if you don’t submit meter readings regularly
Quick self-check
Compare your unit rates and standing charges to the latest Ofgem price cap for your region and payment method.
If you’re paying significantly more, it’s a strong sign you should compare tariffs or speak to your supplier.
Practical Ways to Cut Your Home Energy Costs Now
While you can’t control wholesale markets or government policy, you can take steps to lower what you pay:
1. Make sure you’re on a suitable tariff
- Check if you are on your supplier’s default standard variable tariff
- See if they offer a cheaper fixed deal that suits your usage
- Use accredited comparison tools to see if switching supplier could save you money
2. Provide regular meter readings or use a smart meter
- Regular readings ensure you pay for what you actually use
- A smart meter can give you near real-time usage data and more accurate bills
3. Tackle home energy efficiency
Small changes can add up, especially with high unit rates:
- Improve insulation and draught-proofing to reduce heating demand
- Use thermostatic radiator valves and smart heating controls
- Switch to LED lighting and energy-efficient appliances
- Be mindful of high-consumption appliances such as tumble dryers and electric heaters
4. Check if you’re eligible for support
- Warm Home Discount (if available and you qualify)
- Local grants for insulation or boiler upgrades
- Priority services and hardship funds from some suppliers

Future energy prices depend on many global and domestic factors, including:
- Gas supply and storage levels across Europe
- Geopolitical events affecting energy markets
- Weather patterns and demand spikes
- Investment in renewables and grid upgrades
- Future government decisions on where to place policy costs (on bills or through taxation)
While wholesale prices have eased from previous peaks, they remain higher than historic averages. That means:
- Home bills are unlikely to return to pre-crisis levels in the near term
- We may see further fluctuations in the Ofgem price cap
- Energy efficiency and smart tariff choices will stay important for keeping costs under control
Stay proactive, not reactive
Instead of waiting for the next price announcement, focus on what you can control today: your tariff, your usage and any support you’re entitled to.
