Price cap update (consumer reference only)
Ofgem announced on 27 May 2026 that the consumer default-tariff price cap rises 13% from 1 July to 30 September 2026 to £1,663 per year on the updated TDCV.
Business energy is not covered by the price cap. Non-domestic contracts price off the same wholesale market though, so the 28% three-month rise in wholesale gas driving today's consumer cap also feeds into renewal quotes for SMEs. Time fixed renewals carefully.
This is a commercial intelligence reference, not an aggregator and not a price-comparison site. The guides do not recommend specific suppliers, do not contain affiliate links, and do not refer business to brokers. Every source cited is a primary regulatory, legislative or industry body publication. Where a guide is uncertain on a point of fact, it says so.
How to read this hub: the seven sections below are organised by reader intent, not topic. Start in the section that matches the moment you're in. Each guide stands alone, but most include cross-references to related guidance where it adds context.
I'm setting up energy supply for the first time
8 guides
New premises, new lease, or a new business taking on its first commercial supply. This section covers the mechanics that don't apply to domestic energy: how supplier licensing works, what a deemed contract is, why your first bill may be unexpectedly high, and the meter and supply infrastructure questions you need to resolve before you sign anything. Read this section if your first thought is 'how does any of this work'.
Commercial energy bills carry costs that no domestic bill does: capacity charges, Climate Change Levy, transportation pass-throughs, and VAT rates that depend on what your business does. This section is for finance directors, office managers, and owner-operators who want to read their own invoice rather than rely on the broker's summary. Includes the reduced 5% VAT route, how AQ and EAC affect what you pay, and how to benchmark your unit rate against published market averages.
Energy consumption profiles vary dramatically by sector. A pub spends a different proportion of its turnover on energy than a manufacturing plant or a serviced office. This section provides sector-specific guidance: typical consumption ranges, the operational decisions that drive your bill, and the procurement strategies that work for your business model. Read the section for your sector first if you want to benchmark, then return to the bill-explainer section if your numbers look off.
The most commercially consequential decisions in a business energy contract happen in the renewal window, between 90 days and 30 days before expiry. This section covers what suppliers and brokers are legally required to tell you, what an exit fee can and cannot be enforced for, the difference between rollover and out-of-contract rates, and the mechanics of the switch process itself. If your contract end date is within the next six months, start here.
Wrong bill, supplier failed, debt block on a switch, threatened disconnection, mis-sold contract, or a payment plan that needs renegotiating. This section is the practical dispute and recovery playbook: the formal complaint procedure, the eight-week deadlock rule, when to escalate to the Energy Ombudsman, how the warrant of entry process works, and the routes available when a supplier won't engage. Most of these problems are fixable, but only if you act before the next billing cycle.
Practical cost reduction sits in three places: improving the contract you're on, reducing the energy you use, and generating or storing your own. This section covers all three: the audit and efficiency checklist that quantifies easy wins, the renewables route from rooftop solar through corporate PPAs to EV charging infrastructure, and the structural changes (capacity reviews, demand management) that can move the larger numbers on a half-hourly settled site.
Mandatory reporting (SECR), large business audit obligations (ESOS), and the active regulatory reform programme (Ofgem's non-domestic market review, the Energy Act 2023, REMA, microbusiness definition reform, broker regulation). This section is for sustainability leads, company secretaries, and senior finance teams who need to know what's currently required and what's coming. Updated as Ofgem and DESNZ publish consultation outcomes.
A separate Kael Tripton comparison hub covers the supplier-ranking and rate-comparison angle. The guides linked below are commercial-comparison style rather than reference-style, but the underlying data sources and editorial standard match this hub. Linked here for readers who want to see suppliers compared directly.
The comparison-style entry point: three guides ranking UK business energy suppliers, electricity rates and gas rates. Useful if you want a supplier-by-supplier comparison rather than the topic-by-topic reference structure of this hub.
This hub is updated as new guides are published and as the regulatory landscape changes. Cluster current as of 12 May 2026 · 65 indexed guides · Browse other hubs
