Haven Power: 2020 Reviews, Contact number, Tariffs & Login

Haven Power is a business energy supplier based in Ipswich, Suffolk. It was set up in 2005 and offers fixed and variable rate tariffs with an option for renewable energy so your business can be part of the low carbon economy.



While on their website customers praise Haven Energy, the company sadly generally has quite a lot of negative reviews online.

They provides clear information on their website for potential customers to find out about them. There are various reviews and case studies on Youtube from high profile companies such as Yeo Valley who tell about their good experience with the company's customer service.


Haven Energy doesn't provide customer reviews on its website. More generally, there are very few reviews of Haven Power, they are mostly on Facebook, where customers left negative reviews about them.

Provided below are the various sites through which they have been reviewed and their respective ratings:

Customers have taken to Google Reviews to express their opinions and review Haven Energy. The reviews on the platform are mixed with ratings ranging from 5 to 1 star. On Google reviews they currently have a rating of 2.2 stars.

On the positive side customers praise their customer service and competitive pricing. Customers liked that they have personalised service and a dedicated customer service advisor who has direct contact numbers and email addresses and that they could talk to the same person each time for any issue.

Low Costa Mill Holiday Cottages in Pickering North Yorkshire claimed that they were "proud to be supplied with Biomass Renewable Energy from Haven Power."

On the flipside there are many disatisfied customers who have left one star reviews of the company.

Customers complained about having to pay a fixed direct debit price that was much higher than the cost of their energy usage. People initially thought this was a mistake by the company but when the company failed to refund them the money or reduce their billing people felt they had been conned. They accused Haven Power of not being upfront and honest about the billing amount before setting up the direct debit.

Customers went on to say that it was difficult for them to receive a refund from Haven Power and are still pursuing it. You should do your research and get all the information you can before committing to a fixed direct debit amount to protect yourself again from overpaying.

It seems that Haven Power received positive reviews from 2013-2016 achieving 5 stars. However, since 2016 they currently have all negative, 1 star reviews. This would seem to indicate that recently the quality of the service has decreased considerably.

Business Energy Tariffs & Prices

Haven Power offer fixed and variable rate tariffs to businesses. Their clients range from small and medium sized businesses to large industrial and commercial companies like Yeo Valley.

Every customer who works with Haven Power gets their own dedicated customer service agent who they can contact directly should they have any queries about their account or problems.

Small and large businesses can choose between a variety of fixed or flexible tariffs. The type of tariffs available will depend on the energy usage of each individual company.

Fixed tariffs

Fixed rate tariffs allow you to effectively manage your budget. By fixing in the energy price, you are not left vulnerable to the price changes on the wholesale energy market. Haven Power offer different levels of fixed rate tariffs ranging from completely fixed, meaning that the prices are unchanged for the duration of the contract, to partially fixed billing, which pass on some variable costs that make up your tariff like third party costs.

Haven Power have a range of fixed tariffs for large business owners to choose from:


The Complete Tariff covers both energy and non energy costs. This covers all of the third party costs so you don't have to worry about anything.


The Assured Tariff covers energy and some non-energy costs. This tariff covers some third party costs such as Capacity Market, Cintract for Difference and Energy Intensive Industry schemes (EII).


The Only Tariff covers just the third party costs which are listed individually on your bill.

Flex tariffs

For those people on Flex tariffs, Haven Power has a dedicated trading desk.

These flexible rate tariffs give you the control to buy your own electricity, taking advantage of wholesale price movements. You can buy the electricity through Haven Power’s trading desk which provides information on how to buy energy.

All of Haven Power’s variable rate tariffs pass on third party costs and they are all listed on your bill transparently.

Haven Power have a range of Flex tariffs for large businesses to choose from:


With the Pro Tariff you can buy electricity at varying times in order to take advantage of fluctuations in the energy market. Third party costs are passed through transparently.

Flex Combi

The Flex Combi allows you to flexibly buy energy at wholesale market prices but locks in third party costs.


Portfolios help smaller companies access flexible trading by pooling their consumption.

Third Party Costs

Third party costs can account for up to 60% of your energy bill. They are sometimes known as non-energy costs or non-commodity charges

These costs are obligatory charges, levies and taxes which help to maintain the energy industry in the UK. They are variable.

They can generally be divided into two categories:

Network costs– which cover the delivery of power to meters and maintenance of the power grid. Examples of these are Distribution Use of System (DUoS), Transmission Use of System (TNUoS) and Balancing Use of System (BSUoS).

Policy costs – Government policies aimed at encouraging decarbonisation and renewable energy development. These include charges such as the Climate Change Levy (CCL), as well as subsidy schemes including Renewables Obligation (RO), Feed-in-tariff (FiT) and Contracts for Difference (CfD).

These costs are generally rising year on year and are set to rise even more with the uncertainty of Brexit and the increasing focus on renewable energy.

  • Demand side response management

Energy Mix

The latest fuel mix figures for Haven Power were published in March 2017 and show the contribution of each fuel or energy source to the electricity make up.

As of January 2018, Haven Power will not charge any extra for your business to receive 100% of your energy from renewables. This comes after news that in 2017, 67% of all new businesses energy contracts in the sector were renewable power.

Its renewable electricity is made up in large part from biomass energy which is supplied by its parent company, DRAX group.

Their energy is sustainably sourced and has a carbon footprint 80% lower than coal, even taking into consideration extraction and transportation.

Environmental impact 94g CO2/kWh plus 0.00025g high level radioactive waste/kWh.

What is Biomass Energy?Any electricity generated from burning wood or other organic materials.

Feed In Tariffs

Feed-In Tariffs (also known as FITs) are the electricity part of what some people call Clean Energy Cashback.

This scheme pays companies and individuals for creating their own “green electricity”.

These tariffs have been introduced by the Government to help enocurage the production of renewable energy in the UK towards the government target of 15% of total energy from renewables by 2020.

Haven Power can advise their customers about how they can take advantage of the scheme in their own businesses and on the advantages and disadvantages of the scheme in general.

Haven Power is owned by Drax Group, who operate the largest renewable energy generator in the UK. The parent company recently acquired business energy supplier Opus Energy for £340m. This will boost Haven Power's growth into the small and medium business market.

Drax is looking towards a coal free future and in order to achieve this, it has submitted planning permission to convert one of its 3 remaining coal fueled power stations into a biomass power station. This was made after the government said that coal must be phased out by 2025 in order to meet climate targets.
