SSE and npower are two long-standing names in the UK business energy world, but the comparison isn't quite as even as it first looks. SSE Energy Solutions still serves businesses of every size, from sole traders to large corporates, with its own wind and hydro generation behind its tariffs. npower, however, now trades as npower Business Solutions, part of the E.ON UK group, and today it focuses mainly on larger businesses. Smaller businesses that used to hold an npower contract have largely been moved across to E.ON Next.
This business energy comparison looks at tariffs, contract length, pricing structure, renewable credentials, customer service, smart tech and fees, so you can weigh up SSE Energy Solutions and npower Business Solutions.

Which Supplier Offers Better Business Energy Tariffs?
Neither SSE nor npower publishes a single standard business rate, because pricing depends on:
Business location
Annual consumption
Industry type
Meter type
Contract length
Credit profile
Regional distribution charges
It's worth noting that the two suppliers structure their tariff ranges quite differently. SSE still publishes named tariffs and indicative price sheets for businesses of every size, while npower Business Solutions works almost entirely on bespoke quotes for larger businesses, with no published rate card for new customers to browse.
SSE Tariffs
SSE Protect
A fully fixed price plan that locks in unit rates and non-commodity costs together, typically for terms of up to three years, with 100% renewable electricity included as standard.
Best for:
Small and medium-sized businesses wanting a single, all-in fixed quote
Businesses that want renewable electricity without a separate green tariff
Owners who'd rather not track non-commodity cost changes separately
SSE Choice
Fixes the wholesale unit rate for up to five years, while non-commodity costs such as network charges and levies remain variable and pass through as they change.
Best for:
Businesses comfortable separating unit rate certainty from non-commodity cost movement
Medium-sized businesses wanting a longer fixed term than Protect offers
SSE Shaping
A flexible, live market-priced tariff aimed at larger businesses. Usage profile is fixed for the contract, but pricing tracks the wholesale market.
Best for:
Larger businesses with the resource to manage market-linked pricing
Organisations wanting to buy energy in tranches rather than lock in one rate
SSE Cash Out
Lets businesses with on-site generation, such as solar panels or battery storage, sell power back to the grid for extra revenue.
Multi-Site Agreements
Single contract solutions for organisations managing several premises under one account, tracked through the SSE Clarity platform.
npower Tariffs
Fixed Price Contracts
Bespoke fixed-price contracts covering unit rates, with terms typically available up to five years, agreed directly with a dedicated account manager rather than quoted online.
Best for:
Larger businesses wanting budget certainty negotiated to their own usage profile
Organisations with complex, multi-meter portfolios
Flexible and Market Tracker Contracts
Variable and flexible tariffs that track wholesale market prices during the contract term, aimed at larger businesses that can manage market-linked pricing.
Best for:
Larger businesses with in-house energy management capability
Organisations wanting to buy energy in tranches to spread market risk
Green Energy Contracts
REGO-backed renewable electricity matching and gas offsetting options, available across npower Business Solutions' fixed and flexible contracts.
Unmetered and No Standing Charge Options
Support for unmetered supplies, such as street lighting and signage, billed on estimated usage rather than a meter reading, plus no standing charge options for seasonal or low-usage sites, usually at a higher unit rate in exchange.
Multi-Site Agreements
Portfolio-level contracts for organisations managing many meters and premises, coordinated through a single account manager.
Tariff Comparison Table
Tariff Type | SSE | npower |
Fixed Rate | Yes, up to 3 years (Protect) or 5 years unit-only (Choice) | Yes, bespoke, up to 5 years |
Variable/Flexible Rate | Yes, via Shaping | Yes, bespoke tracker and flexible contracts |
Time-of-Use Tariffs | Yes, seasonal time-of-day options | Limited, bespoke only |
Renewable Tariffs | Yes, included as standard on fixed tariffs | Yes, REGO-backed, available on request |
Solar and Battery Export Tariffs | Yes, via Cash Out | Limited |
Multi-Site Contracts | Yes | Yes |
No Exit Fee Option | Limited | Limited |
Half-Hourly Meter Tariffs | Yes | Yes |
Winner: SSE, for smaller and medium-sized businesses that want a published, named tariff range and renewable electricity included as standard. npower remains a strong option for larger businesses that want a bespoke, account-managed contract, but it's worth knowing upfront that npower Business Solutions no longer serves small businesses directly. If your usage is below roughly 100,000 kWh of electricity or 293,000 kWh of gas a year, your quote is more likely to come from E.ON Next instead.
How Do Contract Lengths Compare?
SSE Contract Terms
Contract Type | Typical Length |
SSE Protect | Up to 3 years |
SSE Choice | Up to 5 years (unit rate only) |
SSE Shaping | Flexible, tied to market pricing |

Fixed Price Contracts | Bespoke, typically up to 5 years |
Flexible/Tracker Contracts | Bespoke, tied to market pricing |
Green Energy Contracts | Fixed term, varies by product |
Contract Length Scorecard
Factor | SSE | npower |

Long-Term Fixed Procurement | Good, fixed terms up to 5 years on Choice | Excellent, bespoke fixed terms up to 5 years |
Time-of-Use Flexibility | Good, seasonal time-of-day tariffs | Limited, mostly bespoke |
SSE vs npower Pricing Structure
Business energy quotes typically include:
Unit Rate
Price charged for each kWh consumed. As an example, SSE's published April 2026 price sheet listed a standard non-half-hourly electricity unit rate of around 35.5p per kWh for Profile Class 1 or 3 customers, though your own rate will depend on location, usage and credit profile. npower Business Solutions doesn't publish a standard unit rate at all. Every quote is bespoke, based on your consumption, contract type and market conditions at the time you apply.
Standing Charge
Daily fee covering infrastructure and administration. SSE applies a standing charge across its core tariff range, published on its indicative price sheets, though a no standing charge option can be available on qualifying meters. npower Business Solutions charges are entirely bespoke, so any standing charge is agreed as part of your quote rather than published in advance.
Pass-Through Charges
May include:
Network costs, as explained in our guide to pass-through and fully fixed energy contracts
Balancing charges
Government levies
Capacity Charges
Applicable to some larger business connections with both suppliers, and more common on npower's half-hourly metered accounts.
Pricing Transparency Comparison
Area | SSE | npower |
Online Quote Availability | Good, indicative price sheets published | Limited, quotes handled via account manager |
Upfront, All-In Pricing | Clear on Protect, less so on Choice | Bespoke, agreed directly with account manager |
SME Simplicity | Good | Limited, SME accounts largely redirected to E.ON Next |
Large Business Procurement | Good | Strong |

Pros and Cons of SSE
Advantages
Own Renewable Generation. SSE supplies electricity from its own UK wind and hydro assets, giving its standard tariffs a low-carbon starting point without relying solely on offset certificates.
Broad Tariff Range Across Business Sizes. Named tariffs cover everything from sole traders on SSE Protect to larger businesses on SSE Shaping.
Energy Management Platform. The SSE Clarity platform gives businesses visibility over usage and forecasting alongside their smart meter data.
Established Smart Meter Rollout. A long track record of smart meter installation across business customers of all sizes.
Disadvantages
Weak Independent Review Scores. SSE Business Energy has consistently scored poorly on Trustpilot, with common complaints about billing errors and long wait times on the phone.
Portal Complexity for Micro-Businesses. Some very small business customers report the billing portal feeling more suited to larger accounts than a single-site micro-business.
Limited Export Options. Solar and battery export is available via Cash Out, but SSE offers fewer dedicated export products than some smaller, tech-first suppliers.
Pros and Cons of npower
Advantages
Dedicated Account Manager as Standard. Every npower Business Solutions contract comes with a named account manager, rather than a general customer service queue.
Backed by E.ON Group's Wider Environmental Programme. npower Business Solutions sits within the E.ON UK group, giving it access to broader net zero and environmental investment.
Established Large Portfolio Management. A long history of managing complex, multi-site and multi-meter business energy portfolios.
Gas Offsetting Alongside Electricity Matching. Businesses can combine REGO-backed electricity matching with gas offsetting in the same contract.
Disadvantages
Not Accessible to Smaller Businesses. npower Business Solutions typically only quotes for businesses above roughly 100,000 kWh of electricity or 293,000 kWh of gas a year. Smaller businesses are usually directed to E.ON Next instead.
No Published Rates or Self-Service Quotes. There's no online rate card to browse. Every quote depends on a conversation with an account manager.
Renewable Options Agreed Case-by-Case. Green tariffs aren't sold as a single named product, so businesses need to ask specifically about REGO matching and gas offsetting when they get their quote.

Key Questions to Ask Before Deciding
Before signing a business energy contract, compare:
What is the standing charge, and is there a no standing charge option?
What is the unit rate, and is it published or bespoke?
Is the tariff fixed, flexible or time-of-use?
Are there exit fees?
What happens at contract renewal?
Are renewable or REGO-matched tariffs available, and do they cover gas?
Can smart meters be installed, and how is the data used?
How are out-of-contract rates handled?
Is an account manager provided, and is there a minimum usage threshold?
Can multiple sites be managed under one agreement?
Verdict: SSE or npower for Business Energy?
The right supplier depends largely on your business priorities.
Choose SSE if you want:
A fixed contract with renewable electricity from SSE's own generation assets included as standard
A published tariff range you can compare before you apply
A simple online account for a small or medium-sized business
A longer fixed unit rate via SSE Choice
Choose npower if you want:
A bespoke, account-managed contract for a larger business
REGO-backed renewable matching alongside gas offsetting
Flexible or market tracker purchasing for a complex, multi-site portfolio
A named account manager rather than a self-service portal
For most small businesses, day-to-day supply quality differs little between suppliers, because all providers use the same national infrastructure. However, npower Business Solutions is no longer really a small business option at all, having narrowed its focus to larger, account-managed contracts since becoming part of the E.ON group. SSE, by contrast, still publishes a tariff range that covers sole traders through to large corporates, backed by its own renewable generation. Either way, it's worth using our business energy comparison tool to check current quotes against other suppliers before you sign.
