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.

Finding an Ethical Mortgage



Mortgages are usually the biggest financial ‘product’ that most people ‘buy’. As such they can be particularly lucrative for the banking industry – giving them ever more resources to invest in problem sectors around the world such as the fossil fuel industry.

You can read more about the big five banks and their controversial investments in our guide to current accounts.

The greenest mortgage


There is now only one specifically green mortgage available on the market, which is from the Ecology Building Society.

The Ecology Building Society provides mortgages which promote sustainable housing and communities. This can be for self-build energy-efficient housing, ecological renovation, improvements or conversion, or small-scale and ecological enterprises. It also offers mortgages for boat moorings, woodlands, and shared ownership housing.

Its innovative C-Change scheme offers homeowners discounted mortgage rates for energy-efficient homes. There are four levels of discount on a standard variable mortgage ranging from 0.25% to 1.25%.

The level of discount offered depends on the energy standard of the home, so the more energy efficient the home is, the bigger the saving you can make on your mortgage.




Other more ethical options


Building societies are seen as a more ethical option than banks due to the fact they lend mainly in the housing market rather than other more unethical sectors. You can read more about building societies in our guide to savings accounts

Building societies are also mutuals, which means legally they are owned and run for the benefit of their members, rather than shareholders. Not having to generate extra profit for shareholders also means building societies should be able to give customers better deals than banks do.

However, there have been criticisms that directors of many building societies are still helping themselves to large pay packets. Many are listed in our 2018 article on Director’s Pay. Only Nationwide paid its director over £1million, with a payment of £3.4m in 2016. It therefore got a mark in our Anti Social Finance category.

Many building societies ‘demutualised’ in the 1990’s, and become more like banks. Several former mutuals failed in the financial crisis, and others that were still mutual had to be taken over by other building societies or banks.

“They came unstuck due to excessively risky commercial and residential property lending funded by unstable wholesale funding – just as the banks did.” Luckily, restructuring after the credit crunch has “forced building societies to focus again on the core functions that too many had forgotten – long-term stable deposit-taking and prudent, good-quality mortgage lending”.

All the mutuals featured on the table above (including the EBS) pick up an additional mark in our scoring system for company ethos due to their more democratic structures. Mortgage customers are also members, and are able to vote to influence how the society is run.

However, there has been criticism that in practice, they are not all as democratic as they could be. According to the Building Societies Association themselves, “Several societies have introduced a “quick vote” option to their AGM voting form to make it easier for members. Here the member has to cross just one box, and the Board will be appointed to vote on the member’s behalf.”




Switching mortgages


It is possible to switch mortgage provider in the middle of a mortgage period. Normally this is done for financial reasons, but could be done for ethical reasons too. It may involve up-front costs such as having a property surveyed again.

Whether switching, or as a first time buyer, ordinary repayment mortgages are always best from an ethical point of view. Interest-only, or ‘endowment’ mortgages of which there has been much mis-selling in previous years and which rely on stock market investments, will always be problematic ethically – as well as riskier financially.





Company behind the brand

Lloyds Bank (not to be confused with Lloyds of London, which is an insurance firm – they are not connected) is the largest retail bank in Britain. It also owns Halifax and HBOS. 

Lloyds is now fully privately owned again; the government having sold its last remaining shares in May 2017. Lloyds claimed that the sale returned “£894 million more than the original investment”, but once inflation and the cost of government borrowing is taken into account, the public made a loss.

According to Don’t Bank on the Bomb, Lloyds made an estimated USD $2,686 million available to the nuclear weapon producing companies between January 2014 and October 2017. In common with the other big banks, it is still heavily invested in fossil fuels.
