Can gas and electricity bills increase after moving home?
Yes, your gas and electricity bills can increase after you move into a new home. This is often due to the property itself, the tariff you are on, or the way your energy usage changes after moving in.
It is common for new homeowners or tenants to see higher bills in the first few months. That does not always mean something is wrong. In many cases, the reasons are practical and easy to identify.
Why your bills may be higher
A bigger house usually uses more energy than a smaller one. Older homes may also have poorer insulation, single glazing, or outdated heating systems, all of which can push up costs.
Your bill may also be higher if the previous occupier used less heating than you do. People often switch the heating on more often after moving in, especially during colder months or if they are at home more regularly.
If your supplier has set you up on an estimated reading, your early bills may not reflect your actual usage. Once your meter readings are corrected, the amount you pay may go up or down.
Standing charges and tariff changes
Every energy account includes standing charges, which you pay even if you use very little gas or electricity. These charges can vary between suppliers and tariffs, so your costs may increase after the switch to a new contract.
If you have moved into a home and not yet chosen a new tariff, you may be on the supplier’s standard variable rate. This is often more expensive than fixed deals, especially during periods of higher wholesale energy prices.
It is worth checking whether you are on the best available tariff for your household. A quick comparison can sometimes lead to a lower monthly payment.
How to check if your bill is correct
Always provide meter readings as soon as you move in. This helps make sure you are only charged for the energy used after your move, rather than for the previous occupant’s consumption.
Check whether your bill is based on actual readings or estimates. If you think the bill is too high, contact your supplier and ask for a review. In many cases, they can correct the account once the right readings are provided.
How to keep costs under control
Set up a budget based on real meter readings if possible. That gives you a clearer picture of your actual usage and helps avoid surprise bills later on.
You can also reduce costs by improving insulation, lowering the thermostat slightly, and turning off appliances when not in use. Small changes can make a noticeable difference over time.
If your bills remain unusually high, ask for a usage breakdown or consider getting an energy efficiency assessment. This can help you understand whether the property itself is driving up your costs.
Frequently Asked Questions
Bills can rise after a move because the new home may be larger, less energy efficient, on a different tariff, or have different heating and appliance patterns. Your first bill may also include estimated reads, final bills from the previous account, or a longer billing period than expected.
If the supplier estimates your opening meter reading too high, your first bill may include energy you did not use. Checking and submitting an accurate opening read as soon as you move in can help correct this.
Yes. If you are placed on a standard variable tariff or a new supplier's default rate, the unit prices and standing charges may be higher than in your previous home. Reviewing and switching tariffs can reduce costs.
Yes. Bigger homes and homes with poor insulation, old boilers, single glazing, or drafty windows usually need more energy to heat and power, which can increase bills even if your habits stay similar.
Heating demand often rises sharply in colder months, and a new home may be harder to heat than expected. If your move happened before winter, the combination of seasonal use and a less efficient property can significantly raise bills.
Standing charges are daily fixed costs added to many energy bills, regardless of how much energy you use. A new supplier or tariff may have higher standing charges, which can make bills look much higher after moving.
Check the opening meter readings you gave, compare them with your meter, and contact the supplier with clear photos and the move-in date. If needed, ask for a bill correction based on the accurate reading.
Yes. Old appliances, electric heaters, immersion systems, or equipment left connected can use power unexpectedly. It is a good idea to inspect the property and ensure any unused items are switched off or removed.
Working from home can increase daytime heating, lighting, computer use, and hot water demand. In a new home, these extra loads may be more noticeable if the property is larger or less efficient.
A new home may use electric heating, storage heaters, underfloor heating, or an older boiler that costs more to run than your previous setup. Different controls and settings can also make the system less efficient if not adjusted properly.
Yes. Prepayment meters can have different tariffs and sometimes higher standing charges than credit meters. If you moved into a property with a prepayment meter, the cost of each unit may be higher than expected.
Your first bill at a new home may overlap with a final bill from the old property, making it seem like costs jumped. Checking the dates on both bills can show whether you are paying for energy at two addresses.
When moving in, you may use extra power for cleaning, unpacking, laundry, cooking, and longer heating periods. This temporary spike is common and can make the first few bills higher than normal.
Identify the current supplier using the meter number or an industry search tool, then provide an opening meter reading and move-in date. This helps ensure you are billed correctly from the day you took responsibility for the property.
Yes. Drafts, poorly sealed doors and windows, and inadequate insulation can cause heat loss, forcing your heating system to work harder and increasing gas and electricity costs.
Without a working smart meter, readings may be estimated more often, which can lead to billing surprises. A faulty or disconnected smart meter can also prevent accurate tracking of usage and make it harder to spot rising costs early.
If your account is set up on the wrong tariff, the wrong meter type, or the wrong payment method, you may be charged more than necessary. Ask the supplier to review the account details and correct any setup errors.
Yes. More occupants usually means more hot water, cooking, laundry, lighting, and heating use. Even in the same property, a household with more people can see noticeably higher energy bills.
Keep your move-in date, opening and ongoing meter photos, supplier correspondence, tenancy or purchase documents, and copies of all bills. These records help prove when you became responsible and whether the charges are accurate.
Check your opening meter reading, compare tariffs, set up accurate monthly readings, adjust heating controls, improve insulation where possible, and look for unused appliances or leaks. If the increase still looks wrong, contact the supplier and ask for a full review.
