Why scores differ from the homepage. Every guide uses the same six score components but weights them for the job. This one counts renewal price (45%) and trustpilot (20%) most; the homepage's all-round score gives renewal price the biggest share. So Porkbun scores 7.8 here.

What to look for: domains

Renewal priceYou'll pay it every year you keep the domain; first-year offers end.
Term conditionsSome 1p offers need a 3-year purchase upfront.
VATMost UK registrars quote prices ex VAT.
TransfersMoving a .uk domain between registrars is usually free.

A .co.uk domain costs very little in the first year almost everywhere; the real difference is the renewal price, which you pay every year after. We score registrars on renewal price per year inc VAT (45%), first-year price (15%), Trustpilot (20%), support (10%) and two buyer-protection checks (10%): whether the offer works on a 1-year registration, and whether the renewal price is published. Porkbun scores highest at 7.8/10.

How to avoid overpaying for a .co.uk

  • Compare the renewal price. A £1 first year followed by £12.83 a year costs more over three years than a flat £7.99.
  • Check the term. GoDaddy's 1p offer needs a 3-year purchase; most others let you buy one year.
  • Don't forget VAT. UK registrars mostly quote ex VAT; Porkbun prices in US dollars.
  • A free domain with hosting usually lasts for the first year only. See domain and hosting: buy together or separately?
  • Transfers between UK registrars are handled through Nominet's registrar tag system rather than an auth code, and several registrars here list free .uk transfers in.
