Score Ratings

Our ratings are live updated scores from our primary research database. They are based on primary and secondary research across 23 categories - 17 negative categories and 6 positive ones (Company Ethos and Product Sustainability). Find out more about our ethical ratings


Score table

The score table shows simple numerical ratings out of 20 for each product. The higher the score, the more ethical the company.

Move the sliders to customise these scores. 

Click on a product name to see the stories behind the score (subscribers only). 


Full Scorecard

The Full Scorecard shows the 'black marks' for each product, by each of the 17 negative categories. The bigger the mark, the worse the score. So for example a big black circle under 'Worker Rights' shows that the company making this product has been severely criticised for worker abuses.

Scores start at 14.  A small circle means that half a mark is deducted, a large circle means that a full mark is deducted.

Marks are added in the positive categories of Company Ethos and the five Product Sustainability columns (O,F,E,S,A).  A small circle  means that half a mark is added, a large circle means that a full mark is added.

The Full Scorecard is only available to subscribers. Click on the More Detail link at the top of the score table to access it.

Best Buys

as of July/August 2016

As our ratings are constantly updated, it is possible that these companies will not always come out top on the score table.


Triodos Bank scores well on the table and only lends to positive social and environmental projects. Its online cash ISA had an interest rate of 1.25% and a 33 day notice period in June 2016.

The Charity Bank does well on the table and only lends to charities, social enterprises and organisations with a charitable purpose. Its cash ISA had a 33 day notice period and an interest rate of 1% In June 2016.

The Ecology Building society tops the table and only invests in innovative environmental projects. However this option is only available to individuals who were members of the Building Society on 25 September 2015 and have not ceased being a member since this date. Its interest rate was 1.5% in June 2016.


All the other building societies are also a good ethical option. Interest rates in June 2016 for 1 year fixed rate instant access cash ISA appear in brackets.

Topping the table are Coventry (1.3%), Cumberland (1.2%), Leeds (1.2%), Newcastle (1.25%), Principality (1.25%) and West Bromwich Building Societies (1%).

However, please note these options may not be available in every area of the country.


For more widely available cash ISAs we recommend Nationwide Building Society (1.1%) as it is a mutual, or the Co-operative Bank (0.65%) due to its ethical policy.

All the institutions listed above offer more that one type of cash ISA (with the exception of the Charity Bank). See the individual company websites for more information.

What is a cash ISA?

An ISA (Individual Savings Account) is a type of savings account that is the same as any normal savings account except that the interest earned is tax free for a limited annual amount of saving. For the tax year 2016-17 you can save up to £15,240 in a cash ISA if you’re a UK resident aged 16 or over.

Cash ISAs are the most popular type of ISA because there’s no risk to your money (unlike a stocks and shares ISA where the value can fluctuate depending on the state of the financial markets and where it is invested). Savings advice generally is that you should use all of this allowance before saving elsewhere. However you may be able to get a better interest rate in a conventional savings account through loyalty schemes with your existing current account provider.

The market for ISAs, as with most banking products, is dominated by the big 5 banks, Barclays, Sanatander, Lloyds, RBS and HSBC. This isn't good news for ethics and the environment but there are a range of alternatives available.



Divesting your ISA from the fossil fuel industry


Mainstream banks may well take your ISA savings and lend them on to a range of companies involved in controversial activities. This could include: investments in armaments companies, nuclear weapons, animal testing, tobacco, pornography and, of course, the fossil fuel industry. You can read more about the big five banks and their controversial investments in our guide to current accounts.




Corporate policies

Most banks do now have Corporate Social Responsibility (CSR) policies which give the impression that they are as concerned about some of these activities as you are.

However looking at their actual investments, as we have done for the ranking table (above), shows that in many cases these words are little more than hot air.

As you'll see from the table very few banks, other than the three ethical ones at the top, get our best rating for environmental reporting and only four institutions get a product sustainability mark for having an ethical lending policy.

You can read about the most ethical options in the Best Buy box above, all of which make positive investments that benefit society and the environment.





Mutuals (also known as building societies) are also a good option for ISAs. Mutual deposit takers account for about 34% of cash ISA balances. They are seen as a more ethical option due to the fact they lend mainly in the housing market and don't invest in fossil fuels and other unethical sectors.

All the mutuals featured on the table above pick up an additional mark in our scoring system for company ethos due to their democratic structures. They also have branches on most high streets which makes them easy to find and use. You can read more about mutuals and building societies in our guide to savings accounts.




Ease of moving accounts

Government efforts to promote competition in the sector mean that it’s pretty easy to move your whole Cash ISA to a more ethical provider should you choose. In theory it should take no more than 15 days, but you should follow advice on how to do it without losing its tax free status. Contacting the new provider is usually the best place to start.




Company behind the brand


Al Rayan Bank is a Living Wage employer. According to its 2016 report ‘Ethical Banking for Everyone’:

“It was better protected from the recent global banking crisis than conventional banks because its method of banking, where investment must be in tangible assets and not financial instruments based on speculation, did not create the ‘toxic’ assets that were recognised as a root cause of the crisis”.


It was also stated in this report that:

“The source of an Islamic bank’s funding, profits and business investments must be ethical. They cannot be from businesses that are considered unlawful under Sharia, i.e. companies that deal in interest, alcohol, gambling, pornography, speculation, tobacco, arms and other commodities contrary to Islamic values.”[1]

 A May 2016 ‘Global Market Snapshot’ was downloaded from the website of Al Rayan Bank’s parent company, Masraf Al Rayan, showing investments it may be involved in, including oil commodities and companies.[2] According to its 2014 Annual Report, Masraf Al Rayan, was almost 12% owned by the Qatar Holding Company. This was the same company as Qatar Holding LLC, which owns Harrods, and has significant shareholdings in Sainsbury’s, Heathrow Airport Holdings, and Tiffany & Co.
