Switch from expensive deemed tariffs, save money immediately after moving, and find the best energy deals for your new property. Don't overpay on energy bills after your move.
Contact UsAvoid expensive default tariffs when moving property
When you move into a new property, you are automatically placed on a deemed tariff with the existing supplier.
These tariffs are rarely competitive and often cost hundreds of pounds more per year than the best available deals.
Comparing energy prices immediately after moving home is one of the fastest ways to cut your bills in your new property.
Every day you remain on a deemed tariff after moving home costs you money. Deemed tariffs typically cost 20-40% more than competitive fixed deals. A delay of just one month can cost £50-£150 in unnecessary energy charges.
Understanding your default energy rates after moving
A deemed tariff is the default energy rate applied when:
Automatically applied when you become the new bill payer at an address.
When you haven't yet selected an energy supplier for your new home.
When you haven't agreed to a specific tariff with the existing supplier.
Usually variable rate tariffs
Often close to the Ofgem price cap
Rarely the cheapest option available
No exit fees (so you can switch immediately)
Important: You are not locked in — switching is allowed straight away. Under Ofgem regulations, you can switch energy suppliers immediately upon moving into a new property, even if you're on a deemed tariff. There are no penalties or waiting periods.
Timing your comparison for maximum savings
Take meter readings and start comparison immediately. Don't wait even one day.
Complete comparison and initiate switch. Most switches complete in 2-5 days.
Your first bill, meter validation, or cooling-off periods. These aren't required.
Each day delayed on deemed tariffs costs money. Start saving immediately.
Every week you delay means you may be overpaying. Based on average deemed tariff rates versus competitive fixed deals, delaying your switch by just one week can cost £15-£40 in unnecessary charges. A month's delay typically costs £60-£160. The savings from switching begin from the moment you initiate the switch process.

Choosing the right tariff type for your new property
Most households save more by switching to a fixed deal shortly after moving. Fixed tariffs provide price certainty during an already stressful and expensive time. They typically undercut deemed variable tariffs by 15-30%, providing immediate savings while protecting against future price increases.
Typical savings from switching from expensive deemed tariffs
| Household Type | Typical Annual Saving | Key Factors |
|---|---|---|
| 1–2 bed flat | £200 – £350 | Lower usage makes standing charges critical. Flat-specific deals matter. |
| 2–3 bed house | £300 – £500 | Higher usage amplifies savings. Both unit rates and standing charges important. |
| High-usage home | £500+ | Large families or electric heating. Unit rate differences create big savings. |
| Economy 7 property | £250 – £450 | Correct tariff selection critical. Wrong tariff can increase costs. |
| Prepayment meter | £150 – £300 | Default rates often highest. Comparison essential for fair pricing. |
Higher consumption = larger absolute savings from better unit rates.
Regional price variations affect both standing charges and unit rates.
Fixed vs variable, contract length, and supplier competition.
Important considerations for different property types
Very common in flats and new builds. Standing charges matter more than unit rates for low usage.
You must compare Economy 7 tariffs only. Standard tariffs can be 30-50% more expensive.
Still switchable after moving. Comparison is essential as default rates are often 5-10% higher.
Smart tariffs may be available — but they're not always cheaper than standard fixed deals.

Avoid these costly errors when managing energy after moving
Remaining on expensive default rates for weeks or months, costing hundreds unnecessarily.
Believing the existing supplier offers competitive rates. They rarely do for new customers.
Choosing standard tariff for Economy 7 property, increasing costs by 30-50%.
Focusing only on unit rates, missing that standing charges dominate low-usage bills.
Delaying switch until first bill arrives, wasting money on expensive rates meanwhile.
Simply accepting whatever tariff you're placed on without checking alternatives.
These mistakes can easily cost £300–£500+ per year. The combination of staying on a deemed tariff, choosing the wrong tariff type, and delaying action compounds quickly. Many home movers unknowingly waste £500-£800 in their first year by not addressing energy costs promptly after moving.
Moving home puts you on an expensive default tariff — but it also gives you a perfect opportunity to reset your energy costs. Comparing energy prices right away prevents overpaying, locks in better rates, and reduces financial stress during an already expensive transition period.
Escape expensive deemed tariffs that cost 20-40% more than competitive deals.
Secure fixed-price deals that provide budget certainty for 12-24 months.
One less financial worry during the already stressful process of moving home.
