A fixed energy contract gives your business a single unit rate for gas, electricity, or both, set at the day you sign and held for the entire term.

Fixed contracts are the right product when budget certainty matters more than market timing. The unit rate, daily standing charge, and contract end date are written into your supply agreement and held for the term. Your only variable is consumption, which gives finance teams a tight spend forecast and removes the renewals scramble that catches mid-market firms cold every winter.

Purely Energy quotes fixed contracts across more than 30 tier-1 UK suppliers, covering single-site SMEs, mid-market portfolios, and multi-site I&C estates. Every quote we issue breaks the price into four components: wholesale energy, non-commodity costs (the network, policy, and balancing charges that move independently of wholesale), the supplier margin, and our broker margin. Nothing is hidden inside an all-in p/kWh number.

Once you sign, full contract support is included for the life of the agreement: bill validation, query handling, supplier escalations, change-of-tenancy events, and a renewal-timing recommendation 6 to 12 months before contract end. Pair Fixed with Purely Insights (included free) to track consumption against the budget you locked in.

Frequently asked questions

  • How long can I fix for?

    Anywhere from 12 to 60 months. The most common terms we sign are 24 and 36 months. Longer terms typically secure a better unit rate but lock you out of any market downside, so the right answer depends on your view of the wholesale curve. We will model both options for you before you commit.

  • How is the price quoted?

    Every Purely Energy quote breaks the unit price into its four components: wholesale energy, non-commodity costs, the supplier margin, and the Purely margin. You see all four before you sign. There is no all-in price hiding a broker uplift, and no commission paid by the supplier you do not know about.

  • What happens to non-commodity costs during a fixed term?

    On a fully-fixed contract, the supplier prices in their own forecast of non-commodity costs (network charges, RO, FiT, CfD, capacity market, BSUoS, etc.) and absorbs the variance. On a pass-through contract, those charges flow through at actual, which often lowers the headline rate but transfers the risk to you. We quote both and explain which fits your risk profile.

  • Can I exit a fixed contract early?

    Suppliers usually allow termination only via a buy-out, calculated as the wholesale loss they take on the volume you no longer need plus any unrecovered standing charge. For multi-site portfolios we sometimes negotiate explicit break clauses at year 1 or year 2. Tell us if you might need that flexibility before we go to market.

  • What if I add a new site mid-contract?

    Most suppliers will price-match the new site to your existing rate or close to it. We coordinate the connection date with the supplier so you do not end up on a deemed rate during the gap.

  • Do you stay involved after the contract is signed?

    Yes. Full contract support is included for every customer for the life of the agreement. That covers bill validation, query handling, supplier escalations, change-of-tenancy events, and renewal-timing recommendations. We are not a one-and-done broker.

  • Which suppliers do you work with?

    We hold contracts with more than 30 tier-1 UK suppliers covering gas, electricity, and water. Every supplier on the panel offers green electricity and biomethane gas options. We do not name individual panel members on public pages, but we will share the relevant supplier list during your quote conversation.

  • Is there a minimum consumption to qualify?

    No. We quote fixed contracts for single-site SMEs consuming a few thousand kWh a year right through to I&C portfolios consuming 50 GWh and beyond. The supplier panel and quote turnaround scale with your size.
