Snap a photo on your phone or drag in a PDF — most providers' monthly bills work. Rather type it? Four fields: monthly total, speed, contract end, provider.
We run the maths
We compare your current line-by-line spend against every Giant plan we can supply at your address, factoring speed, mid-contract price hikes, and what's actually included vs bolted on.
Get a plain summary
One page: what you pay now, what you'd pay with us, what you'd get extra (or lose), and the honest verdict on whether it's worth switching. No hard sell — sometimes staying put is the right call.
Three specific things a bill won't tell you.
You already know your monthly total. The stuff that saves the money is hidden further down the page — and in your T&Cs.
Find hidden line-rental
Big-ISP bills bury £16-20/mo in "line rental" on plans that don't need a phone line. If yours does, we call it out — even if the answer is "you're already on a decent deal, don't move".
See the mid-contract clause
Most Big-ISP monthlies are index-linked (CPI + 3.9%) on 24-month terms. We flag the exact clause on your bill's tariff — then show what our plain-English 30-day-notice policy would cost you instead.
Zero commitment to talk
Submitting the bill gives you the comparison summary. No sales call unless you ask for one. If you want us to just email the summary and disappear, we do.
