About

Who is Haven Power?

Haven Power Ltd is a renewable-focused business electricity supplier based in Ipswich, Suffolk. Founded in 2006 and owned by Drax Group, it supplies bespoke variable and fixed-rate tariffs to small, medium and large businesses across England, Scotland and Wales. Roughly 93% of its electricity comes from renewable sources, sourced largely from Drax's biomass, solar, wind and hydropower generation portfolio.

Registered as Haven Power Limited, Haven Power uses this legal name for Ofgem licence filings, B2B contracts and any formal communications. The trading name customers see on invoices is the shorter, recognisable form.

The company is headquartered in Ipswich, Suffolk, where it runs its commercial operations, account management and regulatory liaison with Ofgem.

Haven Power was established in 2006. A longer track record means more years operating under Ofgem rules and a wider history of business-customer relationships.

Haven Power is part of the Drax Group plc group, which provides shared governance, financial backing and a wider pool of expertise in wholesale trading, hedging and regulatory work.

The company is regulated by Ofgem, and complaints fall under the Energy Ombudsman alternative dispute resolution scheme,but only for microbusinesses with under 10 staff and under £2m turnover. Larger I&C customers must take complaints through commercial dispute resolution.

Haven Power,pros and cons

Haven Power is the right shortlist candidate if your priority is a near-100% renewable electricity supply for a medium-to-large business, especially if you can benefit from Drax's generation backing and the personalised account model. The trade-offs are real, however: mixed reviews on price competitiveness, customer-service responsiveness and switching ease. Microbusinesses are likely a poor fit; the proposition is built for buyers with the volume to make the Flex tariff or large fixed plans worthwhile.

Strengths

  • Nearly 100% renewable electricity (~93.4%), sourced largely from parent Drax's renewable fleet.
  • Personalised service with dedicated account contacts.
  • Bespoke variable and fixed-rate tariffs adaptable to specific business needs.
  • Free smart meters offered to all customers, plus an EV-fleet service.
  • Backed by Drax Group, the largest UK renewable energy generator.

Watch-outs

  • Mixed customer reviews: Google ~1.9/5, Trustpilot ~2.7/5 with frequent complaints about high prices and customer service.
  • Common complaint: customers report being locked into contracts that are difficult to leave.
  • Deemed (out-of-contract) rates include high standing charges (up to 500p/day for some profile classes).
  • No mobile app for account management; portal only.

Complaints

How to make a Haven Power complaint

The Haven Power complaints process has three internal stages, followed by the option to escalate to the Energy Ombudsman if you are still not satisfied. Put your complaint in writing (by email or post) from the start: this creates the dated record that begins the 8-week Ombudsman clock, which phone calls do not.

  1. 1

    Contact Haven Power customer service

    Raise the issue first with Haven Power's customer service team, quoting your account number. You can email [email protected], write to The Havens, Ransomes Industrial Estate, Ipswich IP3 9SJ, or use the online contact form. The team aims to resolve the issue within one working day.

  2. 2

    Escalation to the customer care team

    If your complaint cannot be resolved straight away, it is escalated to the Haven Power customer care team, who update you every 5 working days on its progress until it is closed.

  3. 3

    Escalate to senior staff

    If you are still unhappy with the proposed solution, the final internal stage is to escalate to senior staff by emailing [email protected].

Escalating to the Energy Ombudsman

If Haven Power cannot resolve your complaint, you can take it to the free, independent Energy Ombudsman. You can do this once 8 weeks have passed since your first written complaint, or sooner if Haven Power issues a deadlock letter stating it considers the complaint final. The service is open to domestic customers and eligible micro-businesses; its decision is binding on Haven Power only if you choose to accept it, and you keep the right to pursue other options instead.

Common questions

Haven Power,frequently asked questions

Contact Haven Power customer service first, ideally in writing by email ([email protected]) or post so you have a dated record. Haven Power aims to resolve the issue within one working day; if it cannot, your complaint is escalated to its customer care team, who update you every 5 working days. If you are still unhappy, you can ask for the complaint to be reviewed by senior staff at [email protected].

Yes, if you are an eligible micro-business or domestic customer. You can take an unresolved complaint to the Energy Ombudsman once 8 weeks have passed since you first complained in writing, or sooner if Haven Power sends you a deadlock letter confirming the complaint is final. The service is free and its decision is binding on the supplier only if you accept it. Larger industrial and commercial customers are not covered and must use commercial dispute resolution.

There are three internal stages: first contact Haven Power customer service; if unresolved, it goes to the customer care team; finally, you can escalate to senior staff by email. If you still cannot reach a satisfactory resolution, an eligible micro-business can refer the dispute to the Energy Ombudsman.

Haven Power is praised for its nearly 100% renewable electricity (around 93.4%) and a personalised, dedicated-advisor service, but customer reviews are mixed: it holds roughly 1.9/5 on Google and 2.7/5 on Trustpilot, with complaints focused on high prices and billing. Citizens Advice ranked it 8th of 16 business suppliers in its October to December 2019 report, placing it mid-table.

Haven Power can be reached by email at [email protected], by post at The Havens, Ransomes Industrial Estate, Ipswich IP3 9SJ, through its online contact form, or via its LinkedIn, YouTube and Twitter accounts. Smart meter, moving and EV queries each have a dedicated email address, listed on the Haven Power contact page.

Haven Power is owned by Drax Group plc, which also owns Opus Energy and operates the UK's largest power station. Drax sources most of its electricity from compressed wood pellets (biomass), which underpins Haven Power's nearly 100% renewable fuel mix.
