About ScottishPower Business
ScottishPower is a major UK energy supplier headquartered in Glasgow and a wholly owned subsidiary of Iberdrola, the Spanish energy multinational and global leader in wind power. Formed in 1990 during the privatisation of Scotland’s electricity industry, ScottishPower became one of the original “Big Six” UK energy suppliers and was acquired by Iberdrola in 2007 for £11.6 billion — a deal that created one of Europe’s largest utility companies at the time.
ScottishPower supplies gas and electricity to approximately five million customers across the UK. Despite its name, the company operates nationwide, including as a Distribution Network Operator (DNO) for Central and Southern Scotland, Merseyside, North Wales, and parts of Cheshire and Shropshire.
For business customers, ScottishPower now focuses exclusively on the SME market. In early 2022, the company withdrew from the commercial and industrial (C&I) energy market, citing “unprecedented challenges” in energy markets at the time. This means very large or high-consumption organisations seeking bespoke industrial procurement are no longer served by ScottishPower Business and should look elsewhere.
ScottishPower was the UK’s first energy company to generate 100% green electricity and operates 38 onshore wind farms with over 1,157 turbines — making its green credentials among the most authentic of any major supplier. All business tariffs include 100% renewable electricity backed by REGOs generated from ScottishPower’s own wind assets.

The ScottishPower Business Checklist
Security
Are their prices fully fixed?
Partially. ScottishPower Business tariffs consist of two elements: a fixed price element covering commodity costs (unit rates and standing charges) protected for the contract duration, and a variable price element covering industry charges — including Distribution Use of System (DUoS), Transmission Use of System (TNUoS), and social and environmental costs — which can change on a quarterly basis.
This structure is explicitly communicated in ScottishPower’s business tariff terms, which is more transparent than some suppliers who bury this detail. However, the quarterly variability of the pass-through element means businesses cannot predict their total energy cost with certainty for the full contract term.
| Charge Type | Status |
|---|---|
| Commodity costs | ✓ Included, Fixed |
| DUoS/TNUoS (transportation) | ✗ Excluded, Variable (quarterly) |
| Social and environmental charges | ✗ Excluded, Variable (quarterly) |
| FIT/RO/CFD | ✗ Excluded, Variable |
| VAT | Excluded (standard) |
| CCL (Climate Change Levy) | Excluded (pass-through) |
Back-billing policy
ScottishPower is an Energy UK member, adhering to the Back Billing Principle that limits retrospective billing to 12 months for meter reading corrections or estimated billing adjustments. This provides important protection against unexpected historical charges.
Credit requirements
ScottishPower Business conducts credit checks when setting up new contracts to assess business creditworthiness and determine appropriate payment terms. Depending on the outcome of the assessment, ScottishPower may require a security deposit or offer alternative payment arrangements to manage credit risk. Newly incorporated businesses or those with limited financial history should be prepared for additional requirements.

What is the termination process?
For non-microbusinesses: 30 days’ written notice is required before your contract end date. Notice can be submitted by email (contactus@scottishpower.com), phone (0345 058 0002), or post to the Glasgow address.
For microbusinesses (fewer than 10 employees, turnover under £1.7m, consuming under 100,000 kWh electricity annually): No advance notice is required to end fixed-term contracts under the 2021 Ofgem microbusiness protections. Exception: evergreen or rollover tariffs require 30 days’ notice.
Note: ScottishPower’s Standard Variable Tariff has no exit fees and no fixed end date — customers on this tariff can switch at any time without penalty. For fixed-term contracts, no cooling-off period applies once a business contract is agreed.
What happens at contract end?
ScottishPower sends renewal reminder notices ahead of contract expiry. If no action is taken, customers are moved to ScottishPower’s Standard Variable Tariff, which features higher unit rates than fixed-term products and can fluctuate with market conditions. Alternatively, businesses are placed on Deemed Tariff rates if they have moved into premises without arranging a contract — this is typically the most expensive rate category.
Both the Standard Variable and Deemed tariffs allow switching at any time with no exit fees, providing flexibility — but at the cost of significantly higher unit rates compared to fixed products.
Is there a rollover period?
No automatic rollover into a new fixed term. Customers who do not renew or switch at contract end are moved to the Standard Variable Tariff until a new agreement is reached or they switch supplier.
What about early exit fees?
Fixed-term business contracts typically cannot be exited early without penalty. The specific exit fee arrangements are detailed in your contract terms. The Standard Variable Tariff carries no exit fee and allows switching at any time — useful as a short-term holding position while procuring a new fixed deal.

Convenience
Payment options
- Monthly Direct Debit (variable monthly or quarterly instalments)
- Fixed monthly Direct Debit instalments
- Monthly bill payments (more expensive than Direct Debit)
- BACS bank transfer
- PayPoint payments
- Prepayment / pay-as-you-go (available for some business sizes)
- Smart prepayment top-up
ScottishPower offers one of the broader payment method ranges of the major suppliers, which may be useful for businesses with specific cash-flow preferences. Direct Debit remains the most cost-effective option.
Online account management
ScottishPower Business provides an online account portal and mobile app for managing accounts, submitting meter readings, viewing bills, and monitoring consumption. An energy efficiency toolkit is available alongside the account portal, offering guidance on usage patterns and cost reduction opportunities. An energy efficiency advice helpline operates 24 hours a day.
The online tools are generally well-regarded for self-service account management, though some customers report that complex queries requiring human intervention can be difficult to escalate beyond online channels.
Customer service standards
ScottishPower Business maintains a UK-based customer service team available Monday to Friday, 9am–5pm by phone (0345 058 0002) and email. Live chat is available through the website during business hours.
However, independent assessments of customer service quality present a challenging picture. Which?’s 2026 supplier assessment rated ScottishPower as the worst performer for customer service among all major suppliers — and second worst overall — a damning finding for any business evaluating suppliers based on service quality. The assessment also flagged ScottishPower as worst for complaints performance and overall customer score. This follows similar poor rankings in 2021.
Trustpilot scores (4.3/5 from ~143,000 reviews) paint a more favourable picture, though the majority of these reviews reflect domestic rather than business customers. Business-specific reviews on Trustpilot identify metering disputes and difficulty resolving billing errors as recurring pain points.
VAT declarations
Businesses eligible for reduced VAT rates (e.g. residential care homes, hospices) can submit VAT declarations to ScottishPower Business. CCL exemptions for qualifying organisations such as charities and educational establishments are also available with supporting documentation.
Services
Smart metres
ScottishPower Business offers smart metre installation for business customers, bookable online or by phone (0800 074 0072, 9am–5pm Monday to Friday). Smart metres eliminate estimated billing, enable real-time consumption monitoring via the online portal, and are recommended ahead of the UK’s Market-wide Half-Hourly Settlement (MHHS) programme.
Energy efficiency services
ScottishPower Business, in partnership with the Carbon Trust, offers energy efficiency advice and guidance to commercial customers. The energy efficiency advice helpline operates 24 hours a day. An online energy efficiency toolkit provides benchmarking, usage pattern analysis, and practical recommendations for reducing consumption and costs.
EV charging
ScottishPower Business provides commercial EV charging infrastructure, including fast, rapid, and ultra charging points. There are no upfront costs for businesses, and end-to-end support is provided to manage charging points. EV charging can be combined with ScottishPower’s 100% renewable energy tariff, creating a fully green vehicle charging solution — particularly relevant for automotive dealerships, hospitality sites with car parks, and professional services firms transitioning company fleets.
Solar panels and heat pumps
ScottishPower offers solar panel installation and air source heat pump solutions through the wider Iberdrola group. These can be combined with business energy tariffs for integrated low-carbon energy management — relevant for owner-occupier businesses looking to reduce grid dependency and energy costs.
New connections
ScottishPower Business can assist with new gas and electricity connections. As a DNO for several UK regions (Central and Southern Scotland, Merseyside, North Wales, parts of Cheshire and Shropshire), ScottishPower has direct network operator relationships in these areas, which can streamline connection processes for businesses in those regions.
Multi-utility supply
ScottishPower Business supplies electricity and gas only. Water supply and telecommunications are not offered.
Environmental
ScottishPower has the strongest renewable credentials of the traditional “Big Six” suppliers, with a genuine operational commitment to wind energy that predates many competitors’ green positioning.
Green electricity
ScottishPower was the UK’s first energy company to generate 100% green electricity and remains committed to this position. All ScottishPower business tariffs include 100% renewable electricity, generated from the company’s own 38 onshore wind farms with over 1,157 turbines. This is not offset or certificate-only green electricity — ScottishPower generates the renewable power it supplies, giving its green credentials particular authenticity.
The Renewable for Business tariff provides 100% verified renewable electricity backed by certified Renewable Energy Guarantees of Origin (REGOs) for businesses requiring formal verification of their renewable electricity supply.
Carbon-neutral gas
ScottishPower does not currently offer carbon-neutral gas as a standard product. Gas supply is standard natural gas. Businesses with whole-energy sustainability targets requiring carbon-neutral or offset gas should explore specialist green suppliers.
Standard fuel mix disclosure:
| Source | ScottishPower | UK Average |
|---|---|---|
| Renewable (wind) | 100% | 37.9% |
| Coal | 0% | 2.5% |
| Gas | 0% | 39.4% |
| Nuclear | 0% | 16.6% |
| Other | 0% | 3.6% |
ScottishPower’s 100% renewable electricity generation from its own wind assets is a genuine market-leading position among major suppliers.
Charity and community
ScottishPower has maintained a partnership with Cancer Research UK since 2012, having raised over £20 million through employee fundraising, tariff contributions, sponsorship of Race for Life and Stand Up To Cancer campaigns. The company won the Behavioural Change Campaign of the Year award at the UK Green Business Awards 2025 for its Half Price Weekends demand-response initiative.
Iberdrola’s global investment in renewable infrastructure — including £5.4 billion approved by Ofgem for Scottish transmission network upgrades as part of a £28 billion UK grid improvement programme — demonstrates long-term commitment to the UK’s energy transition.
Sector Fit Assessment
| Sector | Suitability | Notes |
|---|---|---|
| Hospitality | ⭐⭐⭐ Moderate | 100% renewable electricity appeals to hospitality businesses with sustainability credentials to maintain. EV charging relevant for hotels with guest parking. Which? service concerns may give pause for busy operators needing responsive account support. |
| Manufacturing | ⭐ Very Weak | ScottishPower withdrew from the C&I market in 2022 and no longer serves large industrial accounts. Manufacturing businesses above typical SME consumption levels cannot be supplied by ScottishPower Business. |
| Retail | ⭐⭐⭐ Moderate | 100% renewable electricity suits retailers with ESG or sustainability branding. Online portal works for multi-site monitoring. Limited to SME-scale accounts only. |
| Education | ⭐⭐⭐ Moderate | 100% renewable electricity and VAT/CCL exemption support make ScottishPower relevant for schools and colleges with sustainability commitments. UK-based team and energy efficiency advice via Carbon Trust partnership add value for education sector. |
| Healthcare | ⭐⭐⭐ Moderate | Suitable for GP surgeries, dental practices, and care homes. VAT support for residential care available. Which? service concerns are worth weighing for healthcare businesses requiring reliable account management. |
| Automotive | ⭐⭐⭐⭐ Good | Strong fit for automotive sector given the EV charging infrastructure offering (fast/rapid/ultra, no upfront cost) combined with 100% renewable electricity — a credible green proposition for dealerships transitioning to electric. |
| Professional Services | ⭐⭐⭐ Moderate | 100% renewable electricity at no premium suits professional services firms with ESG reporting obligations. However, Which?’s worst-in-class 2026 customer service rating should give pause for businesses where account support is important. |
| SMEs (General) | ⭐⭐⭐ Moderate | ScottishPower’s genuine 100% renewable credentials without a price premium is a real differentiator. However, the Which? 2026 service assessment — worst for customer service, second worst overall — is a serious consideration for any SME evaluating suppliers. |

Telnergy’s Take
Our Professional Assessment
ScottishPower Business presents a genuine tension between its market-leading renewable credentials and its stubbornly poor customer service track record — a combination that makes it simultaneously one of the most and least straightforward suppliers to recommend.
What we like:
100% renewable electricity is the real thing: ScottishPower doesn’t purchase renewable certificates to offset fossil fuel generation — it generates its own renewable electricity from 38 wind farms across the UK. This is a materially different proposition to suppliers claiming green credentials via REGO purchases from third-party generators. For businesses with genuine sustainability commitments, supply chain ESG requirements, or net zero reporting obligations, ScottishPower’s green electricity has authentic provenance that competitors struggle to match at this scale.
Iberdrola’s financial stability: As a wholly owned subsidiary of one of the world’s largest energy companies — Iberdrola operates in 35+ countries — ScottishPower carries negligible insolvency risk. The £11.6 billion acquisition price in 2007 reflects the strategic value Iberdrola placed on UK energy infrastructure. Long-term contract security is as strong as any supplier in the market.
Transparent tariff structure: ScottishPower’s explicit documentation of fixed vs variable elements in its business tariffs — with quarterly pass-through charge updates — is more transparent than suppliers who obscure this split. Businesses know what they are agreeing to, which aids budgeting.
Broad payment flexibility: The range of payment options — including PayPoint and prepayment for smaller businesses — is wider than many major suppliers, providing genuine flexibility for businesses with non-standard cash-flow requirements.
EV charging without upfront costs: The no-upfront-cost EV charging infrastructure offer, combinable with 100% renewable electricity, is a compelling package for businesses with vehicle charging requirements.
Watch points:
Which? 2026 assessment is damaging and current: ScottishPower was rated worst for customer service among all major suppliers in Which?’s 2026 assessment, second worst overall, and worst for both complaints performance and overall customer score. This follows a similar position in 2021 and reflects a structural service quality issue rather than a temporary blip. These aren’t subjective impressions — they are based on surveying thousands of ScottishPower customers and assessing the company’s own complaint resolution data.
Withdrew from C&I market: The 2022 exit from the commercial and industrial energy market limits ScottishPower’s relevance for larger businesses. If your consumption exceeds typical SME levels or you require bespoke large-account procurement, ScottishPower cannot assist.
Business-specific Trustpilot evidence: Filtering business reviews from Trustpilot reveals recurring themes around metering disputes, billing errors that are difficult to resolve via online channels, and account management gaps. The overall 4.3/5 score reflects predominantly domestic customer sentiment.
Restricted business hours: 9am–5pm Monday to Friday phone support is narrower than most competitors and may present challenges for businesses that operate outside standard office hours and occasionally need urgent account support.
No carbon-neutral gas: For businesses wanting to address both electricity and gas sustainability, ScottishPower’s natural gas supply without an offset option is a limitation. Specialist green suppliers offer certified carbon-neutral gas products.
Bottom line:
ScottishPower Business sits in an unusual position: genuinely exceptional on environmental credentials, genuinely poor on independently assessed service quality. For businesses where 100% renewably generated electricity is a material decision factor — whether for sustainability reporting, supply chain requirements, or corporate values — ScottishPower’s authentic wind-generated supply is hard to match among major suppliers.
However, the Which? 2026 findings cannot be dismissed. Businesses requiring reliable, responsive account management — particularly when issues arise — face a meaningful service quality risk with ScottishPower. The fact that this concern has been evidenced repeatedly across multiple years suggests it reflects structural limitations rather than temporary difficulties.
Our recommendation: ScottishPower Business is worth considering specifically for SMEs where renewable credentials are a primary driver and account management complexity is expected to be low. For businesses anticipating any significant level of supplier engagement — billing queries, change of tenancy, metering issues, or contract disputes — the service quality evidence argues for exploring alternatives.
We regularly quote ScottishPower alongside other suppliers. Their rates are competitive, and for straightforward accounts with smart metres and uncomplicated supply, the service experience can be adequate. The risk is concentrated in what happens when something goes wrong.
