This represents a 7% reduction (£117 annual saving) that applies automatically to ALL Octopus Energy customers.
If you switch to Octopus Energy in March 2026 using the referral code, you get:
- £50 credit immediately (after your first Direct Debit payment)
- £117/year saved automatically from April 1st onwards
- Total first-year saving: £167+ compared to staying with your current supplier on the old price cap
Real Customer Example
I switched to Octopus in November 2024 using a referral code. My February 2026 bill was £315. With my old supplier on the January price cap, it would have been £465. That's £150 saved in one month. The £50 referral credit appeared 3 weeks after switching, reducing my first bill even further.
After April 1st: My bills will drop another £10/month automatically. I did nothing except switch once and claim the referral credit.

April 2026 Price Cap: What Changes on April 1st
The energy price cap is set by Ofgem (the energy regulator) every three months. From April 1st to June 30th, 2026, the cap drops to £1,641 per year for a typical household. This compares to £1,758 from January to March 2026.
| Period | Annual Cap (Dual Fuel) | Monthly Cost | Difference |
|---|---|---|---|
| Jan-Mar 2026 | £1,758 | £146.50 | - |
| Apr-Jun 2026 | £1,641 | £136.75 | Save £9.75/month |
The reduction comes from two main changes:
- Policy cost reductions: The government removed around £130 in green levies and scrapped the ECO scheme (Energy Company Obligation), saving approximately £60 per year
- Lower wholesale prices: The cost of buying energy fell by £38 per year
Octopus Energy has confirmed it will pass the full savings to ALL customers on both fixed and variable tariffs from April 1st. This happens automatically - you do not need to do anything.
Switch Before April 1st

Claim £50 Credit →Should I Switch Before or After April 1st?
Switch before April 1st, 2026. Here's why:
Scenario 1: Switch in March (Before April 1st)
- You get £50 referral credit immediately
- Your bills start on current rates (£1,758 cap or lower if Octopus offers below-cap pricing)
- April 1st: Your bills automatically drop to £1,641 cap
- Total saving: £50 + £117/year = £167+ in first year
Scenario 2: Wait Until After April 1st
- You still get £50 referral credit
- Your bills start at the new £1,641 cap
- But you paid higher bills in March while waiting
- Total saving: £50 + lost savings from March delay
The earlier you switch, the more you save. Switching takes 2 to 3 weeks, so starting in March means you will likely benefit from both the referral credit and the April price drop.
Where Can I Find the Most Affordable Energy Suppliers?
The most affordable energy suppliers in March 2026 are those charging below the price cap. Octopus Energy has never charged the full price cap since launching in 2015. Their standard variable tariff (Flexible Octopus) typically prices around £15 below the cap, plus they offer fixed tariffs with no exit fees.
For 2026, the competitive suppliers include:
- Octopus Energy: 7.7 million UK customers, Which? Recommended 8 years running, consistently below price cap
- OVO Energy: Second largest, merged with SSE, competitive fixed tariffs
- E.ON Next: Part of E.ON, decent customer service, competitive pricing
However, Octopus Energy stands out because of the combination of below-cap pricing, excellent customer service (Trustpilot 4.8/5 from 700,000+ reviews), and the £50 referral credit available when you use a referral link.
Which Energy Companies Have the Quickest Sign-Up Process?
Octopus Energy has one of the fastest sign-up processes among UK suppliers. The online form takes 5 to 8 minutes to complete. You need your address, approximate energy usage (or a recent bill), and bank details for Direct Debit.
The actual switch completes within 2 to 3 weeks industry-wide. This timeframe is regulated by Ofgem to protect consumers. Some suppliers claim faster switches, but in practice, most take the same timeframe due to industry processes.
What makes Octopus faster than competitors:
- No credit check required (standard for energy switching)
- Digital-first process (no paper forms)
- Automated communication (clear updates via email and app)
- Handles old supplier contact (you do nothing)
Frequently Asked Questions
Does the referral code work with fixed tariffs?
Yes. The £50 referral credit applies to both variable (Flexible Octopus) and fixed tariffs. The April price drop also applies to all tariffs - Octopus confirmed they are passing the savings to fixed tariff customers automatically.
Can I use a referral code if I'm already an Octopus Energy customer?
No. Referral codes only work for new customers. However, once you are a customer, you get your own referral code to share with friends and family. You earn £50 for each person who switches using your code.
What happens to my old supplier after I switch?
Octopus Energy contacts your old supplier and handles the switch. Your old supplier sends a final bill for any energy used before the switch date. Octopus takes over supply on the agreed date. Your supply never drops - it is seamless.
Will my energy supply be interrupted during the switch?
No. Your energy supply continues without interruption. Switching suppliers is purely administrative - the same wires deliver your electricity and the same pipes deliver your gas. Only the billing company changes.
How long does the £50 credit last?
The credit never expires. It sits on your account and reduces your energy bills until it runs out. For a typical household, £50 covers roughly 10 to 14 days of energy bills, depending on usage and season.
