Octopus Energy for Business: what's included and how the £75 referral works

Editorial note: I'm not an Octopus Business customer. I'm a six-and-a-half-year domestic Octopus customer (see the full review), but this post is a published-data summary of what Octopus Energy for Business offers, not a user review. Treat it as a starting point for your own quote comparison rather than a verdict.

If you're trying to work out whether Octopus Energy for Business is worth switching to, this post walks through what's actually in the offering: the tariff range, who's eligible, the £75 referral mechanic, and the structural trade-offs versus other UK business energy suppliers.

What Octopus Energy for Business covers

Octopus Energy for Business is the SME and commercial arm of Octopus Energy. It serves:

• Sole traders and freelancers running a business from a domestic or commercial address
• Micro-businesses and SMEs with standard commercial electricity (and gas) meters
• Multi-site operations: each site can be set up under one account
• Sites with on-site generation (solar, battery storage) on dedicated export tariffs

All electricity supplied is 100% renewable as standard, backed by REGO certificates and Octopus Energy Generation's own wind and solar investments. There's no separate "green tariff" upcharge; renewable is the default.

The signup flow is digital: get a quote with your usage and meter details, pick a tariff, complete signup online, and Octopus handles the switch with your current supplier. Switching typically completes within 2–3 weeks with no supply interruption.

The tariff range, in plain terms

Octopus's main differentiation versus the legacy suppliers (British Gas, E.ON, EDF, OVO) is the breadth of smart and time-of-use tariffs available to businesses. The published lineup includes:

Fixed and variable

• Fixed-term contracts: typical 12 or 24-month locks. Useful when you want budget predictability and the wholesale market looks stable or rising.
• Variable / standard rates: sit close to the Ofgem-equivalent reference for non-domestic supply.

Shape Shifters (smart, time-of-use)

The flagship business tariff. Comes in two variants:

• Shape Shifters Trio: three pricing periods through the day; the cheapest period covers up to 21 hours. Designed for SMEs that can shift discretionary load (dishwashers, EV charging, fridges, light manufacturing) outside peak hours.
• Shape Shifters Agile: half-hourly pricing linked to the wholesale market. More volatile but unlocks bigger savings for businesses that can flex aggressively.

Both require a smart meter. Octopus's published trial results claim 100% of participants saved money, though the size of the saving depends heavily on how much load you can actually shift.

Solar and storage tariffs

For businesses with on-site generation:

• Panel Power: a dedicated export tariff for solar generation.
• Shape Shifters: Export: pairs storage with the smart tariff structure for sites with batteries.
• Electric Match: for multi-site operations, lets generation at one site offset usage at another.

No Standing Charge tariff

For businesses with low or variable usage (e.g. seasonal premises, occasional-use units), Octopus offers a no-standing-charge tariff. You pay a higher unit rate but don't pay for "just being connected." Worth modelling against your usage profile before switching.

Saving Sessions

With a smart meter, business customers can opt into Saving Sessions: short windows where Octopus pays you to use less electricity. Same scheme that runs on the domestic side. The earnings are modest individually but add up across a year.

Who Octopus Energy for Business is a fit for

Based on what Octopus publishes and the business case studies they've shared:

• Strong fit: SMEs comfortable with digital admin, sites that can install a smart meter, businesses with discretionary load to shift (cafes, vets, pilates studios, small workshops), sites with solar or planning to add it, and any business where 100% renewable supply is part of the brand story.
• Weaker fit: Businesses that need a dedicated account manager, sites where a smart meter can't be installed easily, or operations whose energy use is rigidly fixed at peak hours and can't flex.

The case studies on Octopus's business energy blog (featured customers include Bing Pilates, Kimbolton Vets, Box Bear, Hope Chapel) give you a sense of the kind of business currently using Shape Shifters and the savings claimed. Read them as marketing input, not independent reviews.

Where Octopus Business has weaker spots

A few honest caveats worth flagging before signing up:

• Smart meter dependency. Several of the most attractive tariffs (Shape Shifters, Saving Sessions, the export tariffs) require a working smart meter. If your site can't easily install one, you're on the simpler fixed/variable tariffs and most of the differentiation falls away.
• Service is digital-first. Account management is largely through the online portal and in-app chat. There's no traditional account-manager model the way some big legacy suppliers run for larger SMEs. For smaller businesses this is usually a feature, not a bug; for businesses that prefer a phone-first relationship, it's a structural difference worth knowing.
• Multi-utility bundling is limited. If your business takes broadband, mobile and water from a single provider (the Utility Warehouse model), Octopus doesn't replicate that; they're an energy specialist.

I can't speak to first-hand customer-service experience on the business side. The domestic side is where my own data sits; see the full Octopus review for that.

How the £75 business referral works

The mechanic is straightforward:

1. The new business customer signs up via a referral link and selects the business signup flow.
2. After the first direct debit clears, Octopus applies £75 in account credit to the new customer's bill.
3. The referrer also receives £75 in their own account.

The same referral link works for domestic (£50) and business (£75) sign-ups; Octopus determines which reward applies based on which signup flow you complete. The £75 rate has been stable for some time, though Octopus reserves the right to change referral terms at any point.

There's no limit on how many referrals you can make.

How to get a quote and switch

The published process is:

1. Get a quote based on your business size, address, usage profile and meter type.
2. Choose a tariff that matches how you use energy: fixed if you want certainty, Shape Shifters if you can flex load, no-standing-charge if your usage is low, an export tariff if you generate.
3. Sign up online in a few minutes. Octopus contacts your current supplier and handles the switchover.
4. Install or upgrade to a smart meter if needed to unlock the smart tariff range.
5. Switch completes in 2–3 weeks with no supply interruption. The £75 referral credit lands after your first direct debit.

If you want to compare the £75 against alternative suppliers' switching incentives, the broader UK business-energy market typically competes on fixed-deal pricing rather than referral rewards; most legacy suppliers don't have a refer-a-friend equivalent at all.
