7 Best Green Web Hosting Companies UK 2023 [Plus Who I Went With!]

Do you have your own website? Are you looking to reduce your digital carbon footprint?

Join the club!

Whether you’re a full-time business owner, starting a blog on the side or you already want to move to a more sustainable provider, you’ll want to know all about the best green web hosting providers out there. 

The good news is that an environmentally friendly host is still fast, reliable and secure.  

In April 2022, I went through the process of migrating this website across to a green hosting provider based in the UK. And I’m very glad I made the change!

I did a lot of research before I eventually switched to Eco Web Hosting. This was a great choice for me and they have been a superb host since.

If you’re looking to do the same or assessing your options, let’s take a look at eco hosting, what exactly it is and the best green hosting choices out there. 

What does a hosting provider do?

All websites need a good hosting provider. It’s the host that stores your content and website files, then serves it up on computer and phone screens whenever someone lands on your site. Whether this is done fast or slow is usually down to the hosting.

Hosting providers store all this data on servers, which exist in data centres. It’s possible to have many hundreds and thousands of servers in a single data centre. 

The environmental issue with web hosting

In a world of screens, the cloud and never to be seen data servers, you could be forgiven for thinking there’s no carbon footprint or environmental impact associated with the internet and owning a website. But there is.

The main environmental issue to do with hosting a website comes in the form of energy use. This is similar to issue behind cryptocurrencies – you can read about in more detail in this blog on how environmentally friendly cryptocurrencies are.

Running data centres requires a lot of energy. In fact, if Google were a country it would be in the top 90 in terms of electricity usage

It’s also said that around 10% of the world’s electricity consumption now happens on the internet. Some people think this is terrible but I don’t think it’s inherently a bad thing. 

We live in an ever changing world, which is becoming more digital. This means we require more electricity. Compare it to the alternative of using fossil fuels to power human lives and it’s not that bad.

What is green web hosting?

eco web hosting

So, websites and the internet in general requires quite a lot of electrical energy.

The good news is that electricity can be generated in green, renewable ways.

And this is what green hosting is all about.

Although there isn’t a physical presence to your digital-based website, there needs to be a physical presence to where all the site data and files are stored. 

When you choose a green web host, you’re opting for a company who run or use servers and data centres in the most environmentally friendly way possible. 

In short, a green web host will help limit and reduce your carbon footprint.

What does eco friendly web hosting look like?

Eco friendly hosting should be as good as any other hosting.

Getting the basics right, good hosting will be:

  • Fast
  • Reliable
  • Secure

These are non-negotiables.

Just because it’s better for the environment, it doesn’t mean that green hosting should be slow or unreliable. If they were they wouldn’t be a sustainable choice as people would get fed up and leave.

Eco web hosting should be much better than traditional hosting in how it’s powered and operated. 

For example, all data centres with lots of servers get very warm. This means they need some form of cooling system to keep everything functioning correctly. A data centre used by a green hosting company will do this in a cleaner, more eco friendly manner. 

Key points for a more environmentally friendly green host provider:

Here are 5 points that should define a good green web host:

+ Powered by renewable energy

Data centres can be partly or fully powered by renewable energy such as solar, wind, hydroelectric and even geothermal depending on the country they’re located in.

Most centres are powered from national grids, which provide readily available energy at a given time.

However, green providers will buy Renewable Energy Guarantees of Origin certificates (called a REGO) per unit of energy used to certify they have put renewable energy back into the grid. 

+ Energy efficient servers

This is all to do with Power Usage Efficiency, or PUE for short. This is the measure of how efficient a data centre uses energy.

The PUE is given as a ratio of the total energy needed to energy going to computing (as opposed to cooling, lighting and other overheads). The ideal PUE rating is 1.0, which would mean 100% of the energy goes to computing.

The best ‘hyperscale’ data centres, i.e. the big ones, have a PUE of about 1.2. Google has ratio of 1.12.

Big tech companies will use a lot of energy and electricity, but the silver lining I guess is that they will be doing their very best to be as energy efficient as possible. When it comes to electricity, the more efficient you are, the more money you save, which is what matters to the big corporates. 

+ Low impact cooling systems

Related to energy efficiency mentioned above is the cooling system. All data centres will need some form of system to keep things at a cool, steady temperature. This may be via air conditioning, the use of refrigerants or local environment.

A green web host will choose the more eco friendly option. Depending on where the centres are situated in the world, it’s possible to use outside air for cooling, which is one of the best approaches. This can happen in colder places, for example in Sweden, Canada and the UK. 

+ Offsetting emissions

Many green host providers now offer an offsetting angle with their packages. For example, Eco Web Hosting plants 10 trees a month on my behalf for the package I am on. I also offset my own footprint through my Ecologi membership – read my Ecologi review here.

As you’re likely to know, offsetting is good, but it’s not the full answer for being sustainable and eco friendly. Offsetting should always be used alongside other methods that reduce emissions and impact at source. 

+ Green business practices

Taking a wider approach, green hosting companies should care about the bigger picture.

How do they operate as a whole business? Do their offices use renewable energy? Do they publish an environmental report?

Non UK green hosting

Of course, the internet spans the globe. If you live in the UK, you don’t necessarily have to use a UK hosting provider. In theory, your site can be hosted anywhere in the world. I prefer to keep things local where possible, which is why I switched to a green provider in the UK. 

The best environmentally friendly host I can find outside of the UK is Green Geeks. They are one of the industry leaders in green hosting. 

Green Geeks host over half a million websites with data centres in Chicago, Phoenix, Toronto, Montreal and Amsterdam. However, I believe these data centres are not run with renewable energy, instead using fossil fuel power generation. Maybe because of this Green Geeks put three units of renewable energy back into the grid for every unit used. 

Wrap up on environmentally friendly hosting

You’re not short of very good, eco friendly, green website hosting companies that are based in the UK. Many of these companies will host websites across the world and vice versa.

These green hosts make sure they implement strategies and practices to reduce their carbon footprint, which mainly comes by way of energy usage. As well as improving efficiency and sourcing renewable energy power methods, a green sustainable host will also offset carbon emissions with tree planting and carbon reduction projects.
