What is a £150 bill credit energy tariff?

A £150 bill credit tariff is an energy deal that applies a one-off credit (typically £150) to your electricity and/or gas account after you switch and meet the supplier’s terms. The credit reduces your bills rather than being paid as cash.

How do I qualify for the £150 bill credit when switching?

Eligibility depends on the supplier’s offer, but it commonly requires you to complete the switch, keep the new tariff active for a minimum period, and pay by Direct Debit. Some deals apply only to dual fuel (gas + electricity) or selected payment methods. Always check the tariff’s terms before applying.

When will the £150 credit be applied to my account?

Most suppliers apply the bill credit after your switch completes and your first bill is produced—often within 30–90 days. Timing varies by provider and tariff conditions.

Is a £150 bill credit better than a lower unit rate?

Not always. A bill credit can make a tariff look cheaper upfront, but your total cost depends on unit rates, standing charges, your usage, and any exit fees. Comparing the projected annual cost (including the credit) helps you see which option is genuinely best for your home.

Can I get the £150 credit if I switch electricity only?

Sometimes, but many £150 bill credit offers are designed for dual fuel switches. If you’re switching electricity only (or gas only), check whether the promotion applies and whether the credit amount changes.

Are there exit fees on tariffs that include £150 bill credit?

Some fixed tariffs with bill credits include exit fees, while others don’t. If you think you may switch again soon, look for a tariff with no (or low) exit fees and confirm whether you must stay until the credit is applied.

Will switching with bill credit affect my supply or cause downtime?

No. Switching supplier is administrative—your gas and electricity supply stays on throughout, and you won’t need any engineering work in most cases.

How long does it take to switch energy supplier in the UK?

Switching typically completes within a few working days to a couple of weeks, depending on your current supplier, the type of meter, and whether there are any account issues to resolve.

Do I need to provide meter readings when I switch?

You’ll usually be asked for meter readings around the switch date to ensure your final bill from the old supplier and your opening bill with the new supplier are accurate. Smart meters can often submit readings automatically.

How do I find and compare the best £150 bill credit energy tariffs?

Compare tariffs using your postcode and typical annual usage, then look at the total estimated cost after applying the £150 credit, alongside unit rates, standing charges, tariff length, and exit fees.

Why households switch to tariffs with bill credit

Immediate value (when applied)

Bill credit can reduce what you pay over the first billing period(s), helping with seasonal spikes—especially in winter.

Better overall tariff fit

The best deal isn’t always the biggest incentive. We compare unit rates, standing charges, contract length and features.

Switching is simpler than it sounds

Your supply usually stays on with no engineer visit. Most of the time, you just provide meter readings on request.

Dual fuel vs single fuel

Some offers apply to dual fuel only, others to electricity-only homes. We’ll show what you’re eligible for.

Transparent comparison

We focus on the figures that matter: estimated annual cost, tariff terms and when bill credit is added.

Options for different meter types

Smart meters, standard credit meters and prepayment options can have different tariffs and incentives.

How switching with £150 bill credit works

Suppliers may offer bill credit (sometimes described as a “switching bonus” or “welcome credit”) to encourage new customers to join. The value can be up to £150, but it’s not guaranteed for every household or tariff. Below is what to expect.

1) Share your postcode and contact details
We use your postcode to identify your region and available tariffs, then help you compare eligible deals (including any bill credit).
2) Compare tariffs like-for-like
We highlight unit rates, standing charges, contract length, exit fees (if any), and when the bill credit is applied.
3) Choose your preferred supplier
If you proceed, the new supplier handles the switch process. Your energy supply stays on—no interruption.
4) Bill credit is added (if eligible)
Most tariffs add credit after the switch completes and certain conditions are met (e.g., paying by Direct Debit or remaining on supply for a set time).

What “best” really means for a bill credit tariff

Check	Why it matters	What to look for
Unit rates	A high credit can be offset by higher p/kWh pricing.	Compare estimated annual cost with and without credit.
Standing charge	Standing charges vary by region and can add up quickly.	Look at £/day for gas and electricity in your postcode.
Tariff length	Longer fixes may suit stability; shorter deals suit flexibility.	12–24 months are common; check renewal terms.
Exit fees	Leaving early could reduce or remove the benefit of credit.	If you might move home soon, prioritise low/£0 exit fees.
Credit conditions	Some credit is split, delayed or requires Direct Debit.	Check timeframe and requirements to qualify.

Common mistakes when chasing bill credit (and how to avoid them)

Focusing only on the £150 headline

A slightly smaller incentive can still win if the unit rates and standing charges are lower over the full year.

Missing the credit conditions

Some credits are applied after a set period, require Direct Debit, or are split between fuels. Always confirm terms.

Ignoring your usage pattern

High-usage households are more sensitive to unit rates; low-usage households can be hit harder by standing charges.

FAQs: £150 bill credit energy switches

Is £150 bill credit guaranteed when I switch?

No. £150 is a common maximum headline incentive. The actual credit depends on the supplier, tariff and your eligibility (e.g., new customer, payment method, meter type and location).

When will the bill credit be applied to my account?

It varies by tariff. Many suppliers apply credit after your switch completes and you’ve received your first bill, or after a stated number of days. Always check the tariff terms before switching.

Can I get bill credit on electricity-only or gas-only tariffs?

Sometimes. Some incentives are exclusive to dual fuel, while others apply to single-fuel switches. EnergyPlus will show what’s available for your home and meter set-up.

Will switching affect my supply?

In most cases, no. Your energy continues as normal. The change is administrative—your new supplier takes over billing once the switch is complete.

Should I choose a fixed or variable tariff if I want bill credit?

Either can include incentives. A fixed tariff can offer price certainty for a set term; a variable tariff can offer flexibility but may change with the supplier’s pricing. The “best” option depends on your priorities and current rates.

Do I need my current supplier details to compare?

Not always. A postcode-based comparison can show eligible tariffs, but having your annual usage (kWh) or recent bill details helps estimate costs more accurately.

Not sure what to pick? Start with your postcode and we’ll help you shortlist tariffs where the bill credit and the ongoing rates make sense for your home.
