Easily Limited (easily.co.uk) is one of the bigger, more respected domain name/web hosting firms in the UK. They provide a reliable service at an affordable price for both the business and private consumer. Though not the cheapest out there, Easily Limited regularly offer discount vouchers.
The company was formed in 1999 as easywebnames.com under Web Consultancy as a web design firm. They later moved onto the hosting front after figuring out a way to offer cheaper hosting, when at the time a good .co.uk was around £100. They were offering them for under £10.
Today, Easily Limited is part of Group NBT and caters to in excess of 100,000 customers in countries worldwide. The centre is based in the UK, though it doesn't really matter where your domain is hosted (for those based elsewhere) since latency times are low nowadays through massive bandwidth. Additionally, you can also use a discount voucher with Easily Limited wherever you are.
Easily Limited still offer lower priced domain name registration as well as web hosting and related web services, to include Easily Website Creator, which allows even the non-techie to get an e-commerce website off the ground. Customer support is there to help with domain hosting issues, as well as to help with issues on building a website and setting up email accounts.
You can find lower priced domain registration and hosting firms, in particular in the USA, but many of these can be less reliable when it comes to uptime and customer support. They may also not offer a broad range of discount codes like Easily Limited do. These may include deals on e-commerce packages, antivirus program trials, Adwords Vouchers, and so on.
