I am using GoDaddy for my Windows Hosting. I agree their SSL cost is high, but it is possible to use Let's Encrypt SSL certs on their sites. There are YouTube videos that show how.
I have a number of domains registered with GoDaddy, and but haven't registered one recently. They used to offer free emails with domains that lasted forever, but they started offering Outlook 365 and may be trying to wean their clients off the GoDaddy email services.
In the past I've used ASP Host Portal. They offer a lot from Windows and Linux hosting, to shared/dedicated servers and shared/dedicated cloud servers all in different tiers, and also email. They have data centers all over the world including London. It was very affordable. They even have an option where they will manage the dedicated server for you (updates, protection, etc.) The reason why I switched was because on the shared host, someone kept hitting the CPU limit and they said there was nothing they could do about it. It would cause my site to go down for hours at a time. It was happening more frequently so instead of switching to a dedicated server I moved to Azure since I thought it would be good to learn for future employment opportunities.
I second the vote for looking at Azure. For you sub-site, you can use the basic (free or shared) plan if your project's fit the requirements. They don't support custome certificates, however, you can use a free cloudflare account to apply HTTPS (using the Cloudflare cert from CloudFlare to Azure)
They have also added a new pricing model for SQL that is based on usage. To see pricing, go to the Azure Pricing Calculator ()[^], select SQL, for Computer Tier select "ServerLess". The pricing is much more reasonable.
Back to the websites, the Free App Service plan is free (but limited in options), shared starts around $10 per month, and basic is 54.75 per month (B1: 1 Core, 1.75 GB Ram, 10GB Storage).
I don't use MySql, but a quick look at the SAAS (Software as a Service) for MySql shows around $50 per month. It may very likely be cheaper to setup a Linux VM and install MySql, depending on your requirements.
I looked at the pricing using the East US region, but you might want something closer. They have UK South, and North Europe regions for something closer to you, but it may affect pricing.
If you purchase Visual Studio (yearly subscription), you can use the Azure Subscription that gives you 50$ credit per month which allows you to set things up and not have to pay anything as long as you don't exceed the credit. Another option is to get a Test/Dev Subscription which has reduced pricing.
I've found Azure to be very easy to deal with and once you get comfortable with how to manage thing you'll find that it is generally trouble free.
AWS "Lightsail" product has been working well for me.
Windows Server VM with 2 Gig RAM allowance has a predictable USD 20 per month base price.
I have also had good value from "databasemart" in the US who are windows hosting specialists.
I don't know if they are a "windows" host, but have you looked at Siteground? I know they are based out of the UK, but I think their data center is out of Spain. I use them and I really like them, but I am not as advanced a user as you are.
I wasted another 20 minutes today trying to tie everything related to hair to a hippy commune. I couldn't find anything... there were a couple of dead-ends around sigcomm, peocomm, tactcomm but I decided to noncomm.
