npower Business Solutions’ Relationship with E.ON and E.ON Next
After E.ON bought them, npower Business Solutions started operating as “npower Business Solutions powered by E.ON”. This setup lets E.ON cover the whole business energy market.
npower Business Solutions focuses on bigger energy users, while E.ON Next takes care of the smaller ones.
Through this partnership, customers get access to E.ON Group’s resources but still benefit from npower Business Solutions’s specialist know-how.
E.ON’s wider services – like EV charging, renewable generation, and energy optimisation – are now available to npower Business Solutions’s customers.
Eligibility Criteria for UK Businesses
To sign up with npower Business Solutions, your business must use over 100,000kWh of electricity each year.
This targets medium and large companies. If you use less, they’ll point you to E.ON Next.
By focusing on high-volume customers, npower Business Solutions can offer tailored services and dedicated account managers.
If you qualify, you can choose from fixed-price deals, flexible purchasing, or hybrid contracts.
Business Energy Product Range
nBS offers tailored fixed contracts, flex portfolio purchasing, and REGO-backed renewable electricity with EcoAct assurance. Contracts run up to five years. New connections can be powered on in five working days.
npower Business Solutions offers fixed-price electricity contracts up to five years, flexible gas services, and REGO-backed renewable energy for businesses aiming for zero-carbon compliance.
Business Electricity Solutions
You’ve got several electricity contracts to choose from. The Fixed Certainty contract locks in everything – commodity prices, network charges, and environmental levies – so your budget stays steady.
Fixed Commodity fixes the energy price, but network and environmental charges pass through at real rates. That’s ideal if you want some price protection but not total rigidity.
The Fixed Choice contract lets you pick which costs to fix. You can lock in commodity rates and decide on network and environmental charges.
MultiPurchase splits your energy buys across different times in the contract. This way, you can dodge market spikes and maybe save when prices dip.
Market Tracker tracks wholesale energy prices monthly. If you want to ride the market and keep your options open, this is your style.
Business Gas Services
Their gas contracts are set up much like their electricity ones. Fixed Certainty gas contracts lock in everything – commodity, transport, and metering – so you know what you’re paying.
Fixed Commodity fixes the gas price but lets transport and metering charges vary. It gives you certainty on the big chunk of your bill.
MultiPurchase gas contracts let you spread out your gas buys. You can manage price risk and catch market lows.
With the Mid-Term Review on Fixed Certainty contracts, you can ask for new pricing if wholesale markets drop a lot before your contract’s halfway point.
All gas deals come with carbon offsetting options, so you can cut your environmental impact without messing up your budget.
Renewable Energy Tariffs
npower Business Solutions offers UK Business Renewable electricity, backed by REGO certificates. That means your power’s verified as renewable for zero-carbon Scope 2 reporting.
REGO certificates show your electricity comes from UK renewables. npower Business Solutions matches your use with these certificates, usually one per megawatt-hour.
EcoAct assurance means their renewable products meet tough compliance checks. They get audited annually to make sure the REGO backing is solid.
You can add renewables to fixed or flexible contracts. They’ll even give you renewable energy labels to stick on your site, so you can show off your green credentials.
Their renewable tariffs tick all the boxes for WRI GHG Protocol Scope 2 Guidance. No extra paperwork needed for zero-carbon reporting.

Types of Business Energy Contracts
Four main contract types: Fixed Certainty (all costs locked), Fixed Commodity (energy price fixed, pass-through charges), Fixed Choice (pick which costs to fix), and MultiPurchase (flexible buying at different times). Contracts from 1 to 5 years.
npower Business Solutions lines up several contract types for businesses using over 100,000kWh a year. You can go fully fixed or pick something more flexible.
Fixed Energy Contracts
Fixed contracts are for those who want price certainty. You lock in everything – commodity, network, and environmental charges.
The Fixed Certainty tariff gives you the strongest shield against price swings. Everything stays the same for the whole contract.
Fixed Commodity fixes only the energy price. Network and environmental costs move with the market.
Fixed Choice lets you decide on environmental charges – fix them or let them float.
Why pick fixed contracts?
- Bills stay predictable
- No nasty surprises from market spikes
- Easier to budget
- Financial planning gets simpler
These contracts are best if your energy usage doesn’t change much. If you’re all about budget certainty, this is probably your lane.
Flexible Contract Options
Flexible contracts let you buy energy at different times and prices. The Multipurchase tariff is the most flexible option here.
You can split your buys during the contract. That way, you can snag deals when the market’s in your favour.
Flexible contract perks:
- Commodity costs change with the market
- Option to fix network charges
- Decide on fixed or pass-through environmental levies
- Save money if you time it right
These deals need hands-on management. You’ll want someone who knows the market to call the shots.
They’re great for businesses with energy managers or advisors. If you’re okay with some risk for the chance at savings, they’re worth a look.
Contract Lengths and Tariff Choices
You can sign up for contracts lasting up to five years. Longer contracts often mean better rates, but you lose some flexibility to switch.
Contract durations:
- 1-2 years: More flexible, usually pricier
- 3-5 years: Better rates, but you’re locked in longer
You can get electricity and gas separately or together as dual fuel. Dual fuel sometimes means admin is easier and prices are better.
Renewable electricity is an option, and gas offsetting helps lower your carbon footprint without switching to green gas.
Every contract comes with an account manager. They help you figure out your energy use and get the most from your deal.
Variable and Unmetered Services
Variable tariffs move with the market during your contract. Unlike flexible contracts, you don’t control when prices change.
Most businesses use metered supplies, but some need unmetered services for things like:
- Street lights
- Temporary sites
- Small ad boards
- Phone boxes or traffic signals
Unmetered supplies use estimates based on equipment type and hours used, not actual meter readings.
Some seasonal businesses go for no standing charge tariff deals. You skip daily charges but pay higher unit rates.
Variable and unmetered services have their own contract terms. Better to chat with npower Business Solutions’s team to see what fits your setup.
Pricing, Rates, and Charges
nBS pricing is entirely bespoke and quote-based — no published unit rates. Costs depend on consumption volume, contract type, and market conditions. All contracts include options for fixing or passing through network and environmental charges.
npower Business Solutions builds its pricing around fixed and flexible options for big energy users. They let you choose how to handle commodity costs, network charges, and environmental levies.
Electricity and Gas Tariffs
There are four main electricity tariffs for businesses using over 100,000kWh a year. Fixed Certainty locks everything in – commodity, network, and environmental costs.
Fixed Commodity fixes the energy price but lets network and environmental charges float. You get some price protection, but not total lockdown.
Fixed Choice lets you fix commodity and network costs and choose what to do with environmental charges.
Multipurchase is the most flexible. You decide if you want to fix or pass through network and environmental charges, and your commodity costs move with the market.
Gas tariffs work the same way. Fixed Certainty locks in everything. Fixed Commodity fixes the gas price but passes through other charges. Multipurchase keeps things flexible.
Budget Certainty and Wholesale Market Impact
Fixed-price contracts shield you from wholesale energy market swings. You can lock in up to five years, which makes financial planning a lot easier.
Multipurchase tariffs mean you’re riding the market. If prices drop, you save. If they spike, you pay more.
Choosing fixed or flexible depends on how much risk you can handle and your view on the market. Fixed is safe but can cost more if wholesale prices fall.
Account managers help you make sense of all this. They share market insights and help you pick the right time to renew.
Network and Environmental Charges
Network charges cover moving electricity across the grid. You can fix them at the start or let them pass through at actual cost.
Fixing gives you certainty, but you might pay more or less than the real cost. Pass-through means you pay exactly what it costs, but bills can be unpredictable.
Environmental charges are government levies for renewables and carbon reduction. You can fix these or let them pass through, depending on your tariff.
Some industries can skip certain environmental charges. npower Business Solutions can advise on tax breaks and how to claim them.
They also offer renewable electricity and gas offsetting to help you cut your environmental impact without breaking the bank.
Sustainability and Net Zero Commitment
nBS offers REGO-backed 100% renewable electricity, gas carbon offsetting, Corporate PPAs, EV charging infrastructure, and demand-side response. Their net zero services include SECR, ESOS, and ISO 50001/14001 compliance support.
npower Business Solutions wants to help UK businesses hit their environmental targets. They offer energy efficiency advice, renewables, and strategies for reaching net zero.
Corporate Sustainability Initiatives
npower Business Solutions goes beyond just selling energy. They position themselves as an “award winning business energy supplier” focused on sustainability and net zero pathways.
They focus on giving clients value and efficiency in a changing energy world. Sustainability isn’t just a buzzword for them – it’s part of how they see business growing and recovering.
Their sustainability framework mixes energy supply with expert advice. They help businesses shrink their environmental footprint and work towards real change.
They even get involved with policy, sharing business insights with the Department for Business and Trade (DBT). That way, government support for net zero goals is shaped by what real businesses need.
Supporting Net Zero Goals
npower Business Solutions helps businesses develop and put net zero strategies into action. They’ve consulted nearly 100 businesses across sectors like manufacturing, retail, property, transport, professional services, and the public sector to get a grip on real decarbonisation challenges.
This research uncovered the main barriers businesses face on the road to net zero. npower Business Solutions uses these findings to shape their services and inform policy suggestions to government bodies.
Key support areas include:
- Strategic energy planning and net zero pathway development
- Access to funding opportunities and green energy grants
- Policy guidance and regulatory compliance support
- Market analysis and energy contract optimisation
They offer renewable energy choices such as wind, solar, and hydro. You can get fully traceable renewable energy through UK-based generators, so you know exactly where your energy comes from.
npower Business Solutions believes hitting net zero targets is a team effort across all sectors. They’ll work with you to pick the right mix of efficiency measures and renewable solutions.
Carbon Footprint Reduction Strategies
npower Business Solutions brings a full suite of energy efficiency solutions for large businesses aiming to cut their carbon footprint. They blend quick-win energy reduction with long-term decarbonisation planning.
Primary reduction strategies include:
- Energy efficiency audits to spot opportunities for cutting consumption
- Carbon-free supply options through renewable contracts
- Cost reduction programmes that lower emissions and expenses
- Technology integration to optimise usage patterns
Their approach tackles both direct energy use and wider supply chain impacts. This gives businesses a clearer picture of their total environmental footprint.
Energy saving programmes focus on real-world changes that actually add up. You’ll find both immediate improvements and help with planning for bigger, longer-term goals.
npower Business Solutions tracks and reports your progress against carbon targets. This data-driven process means you can show compliance when regulators or stakeholders come asking.
Their carbon footprint services fit alongside your business operations. No need to worry about disruption to productivity or growth.

npower Business Solutions offers a range of digital tools and payment systems to help you manage your energy accounts. You’ll find smart meter services, online access, and flexible billing options built for commercial customers.
Smart Meter Installation and Usage
npower Business Solutions sorts out smart meter installation so you can track your energy use in real time. These meters send readings automatically, so you can skip the hassle of manual checks.
Smart meters show you exactly when you’re using the most energy. That makes it easier to tweak your operations and cut costs.
Accurate billing is another plus. With precise data, you get fewer estimated bills and more control over your energy spending.
To get a smart meter, just speak to your account manager. npower Business Solutions arranges for approved engineers to fit the device at your premises at a time that works for you.
Online Account Management Dashboard
The npower Business Solutions dashboard lets you check your account any time, on any device. You can view bills, track usage, and update details right from the online platform.
If you’ve got multiple sites, you can manage all your accounts under one login. That’s a real timesaver for businesses with lots of locations.
The platform also gives you tools to help cut your energy use. There are analytics and recommendations built in to support efficiency.
You get access to customer support and direct contact with account management teams through the portal. Whether you’ve got policy questions or need a compliance update, you can reach someone easily.
Billing, Direct Debit, and Payment Options
npower Business Solutions offers billing arrangements to suit different business needs. You can pick monthly, quarterly, or annual cycles.

Other payment options include bank transfer, cheque, or paying online. Each has its own processing time, so check what works best for your setup.
Bills come with a detailed breakdown of your usage, standing charges, and taxes. If you’ve got a smart meter, your bill reflects actual usage, not estimates, which makes things much clearer.

nBS has virtually no public Trustpilot reviews (1 review on their own profile). Contact: new business 0330 912 7611, existing customers 0330 912 4754. Hours: Mon/Tue/Thu 9am–5pm, Wed 9am–5pm (CS 9am–12pm), Fri 9am–4:30pm.
npower Business Solutions gets mixed feedback from customers. There’s a noticeable gap between business and domestic reviews.

Summary of Business Customer Reviews
Business customer reviews are hard to assess independently. npower Business Solutions’ own Trustpilot profile has virtually no reviews, and E.ON Next’s profile (4.5/5 from 190,000+ reviews) covers mostly residential and SME customers – not nBS’s large-business clients.
Review Breakdown:
- nBS Trustpilot: Essentially unrated (1 review)
- E.ON Next Trustpilot: 4.5/5 from 190,000+ reviews (mostly residential/SME)
- Independent business reviews: Limited public data available
Customers often praise the quality of service and straightforward communication. Many like the tailored approach for business energy needs.
Negative feedback usually centres on how long it takes to sort out issues, especially with billing. Overcharging comes up too, but it seems less common.
Business clients generally find the service more reliable than domestic options. The commercial focus gives them more specialised support and understanding of business needs.
Switching to npower Business Solutions
Switching to npower Business Solutions is pretty standard for business energy. npower Business Solutions handles most of the process, so it’s not a headache to change suppliers.
You don’t need to give final meter readings when you switch. The new supplier sorts that out for you. You’ll still need to pay the final bill from your old supplier.
Switching Process:
- Contact npower Business Solutions directly
- Provide business details and energy requirements
- Review proposed contract terms
- Complete switch paperwork
If you leave your current supplier early, you might face exit fees. These depend on your contract and how long’s left. npower Business Solutions can help you figure out if switching still makes financial sense.
They offer a range of contracts, including fixed and flexible deals. Large users can get specialist tariffs for high consumption. Both single fuel and dual fuel options are available.
