How we compare deals

Our broadband, mobile phone and SIM-only deals are supplied by Stickee, a UK comparison technology platform that powers price comparison for a range of UK websites and aggregates live tariff data direct from providers. For broadband, when you enter your postcode and pick your address, we query the feed for the deals available at your specific property, not just your postcode area.

The feed is updated Monday to Friday as providers send in changes, and Switchity refreshes on the same cadence, within 15 minutes of a deal refresh. When a provider withdraws or changes a deal, it updates or disappears from our results at the next refresh, so you should never see a tariff that is no longer on sale. Ofcom's standard for comparison sites is that data is updated at least every two weeks; ours updates every working day.

Some offers are only available until a set date. Where the provider gives us that date, the deal shows "Offer ends" and the date, and in the last two days a countdown instead.

On our broadband comparison you can sort results four ways. Whatever sort you choose, every deal that matches your filters is shown, and commission has no effect on the order. Every sort is a deterministic calculation from the deal data itself: two people with the same filters see the same order. One consumer-protection exception: where a provider sells both a 4G and a 5G home broadband product and the 5G costs the same or less, we show only the 5G product, because it is faster for the same money. The 4G product appears whenever it is genuinely cheaper.

• Best value (the default). Ranks deals by their effective monthly cost: the true average you would pay each month over the full contract, including any introductory pricing, every scheduled price rise, setup fees, and the value of any cashback or reward. The deal at the top is the one that genuinely costs least, not the one with the cleverest headline price. This calculation is explained in full below. No provider can pay for a higher position, no commercial arrangement of any kind affects the order, and we never adjust it by hand.
• Monthly cost (low to high). Sorts by the headline monthly price, cheapest first.
• Speed (high to low). Sorts by the provider's advertised average download speed, fastest first.
• Contract length (low to high). Sorts by minimum contract term, shortest first.

When two deals tie. If two broadband deals have the same value for the sort you have chosen, we put them in a fixed order using only what you can see on each deal: lower effective monthly cost first, then lower monthly price, faster speed, shorter contract and lower set-up fee, then the provider and package name in alphabetical order. The same rule sets the order of the deal rows on our area, provider and topic pages. The order in which deals reach us from our data platform never decides a tie.

Mobile phone and SIM-only deals follow the same principle. SIM-only results are ordered by monthly cost, cheapest first. Deals for a specific phone are ordered by total contract cost: the monthly price across the full term plus any upfront cost, so a large upfront payment can never hide behind a low headline monthly. Both can be re-sorted by monthly cost or data allowance. Our phones browse page lists every handset with pay monthly deals in our feed, newest first by release date with ties in alphabetical order, and can be re-sorted cheapest first; nothing else decides that order. The short “Latest phones” strip on our homepage is hand-picked by our team: the current flagship launches from Apple, Google and Samsung in order of launch date. No payment influences either.

When two mobile deals tie on the sort you have chosen, we put them in a fixed order using only what you can see on each deal: lower monthly price first, then lower average monthly cost over the contract, lower total cost, more data, shorter contract and lower upfront cost, then the network and tariff name in alphabetical order. This also decides which deals appear on each page: where a group of tied deals runs across a page break, we fetch the whole group before ordering it, so no tie is settled by our data platform.

Bestseller spotlight. Above the ranked broadband results we sometimes feature the single deal that sold the most on Switchity in the previous calendar month. It is selected purely by the number of sales recorded on our own panel, and the commission we earn plays no part. We update it at the start of each month. If two or more deals tie on the highest number of sales, they are joint bestsellers: we show the one available at your address and, where more than one is, the one with the lowest effective monthly cost. The information button on the card explains how it was chosen, whether it tied with another deal, and which month of sales it is based on. The spotlight never changes the order of the list below it, the featured deal also keeps its normal place in that list, and it only appears where the deal is actually available at your address and matches any filters you have applied.

No provider can pay Switchity to appear higher in the results, and no ranking anywhere on this site is influenced by commission, featured status or any other commercial arrangement. We do not show sponsored placements; if we ever introduce them, they will be clearly labelled as such.

The headline price on each deal is the provider's monthly price including VAT. Business broadband is the exception: providers quote business prices excluding VAT, and so do we, saying so wherever business prices appear. Where a deal has an introductory rate, we show the introductory price, how long it lasts, and the price it rises to afterwards. Setup and upfront costs are shown separately on every deal, as is the minimum contract length and any cashback, gift card or reward.

Effective monthly cost is our measure of what a deal really costs. We add up every monthly payment over the minimum contract term, including any introductory rate and any price rises the provider has scheduled, add the setup fee, subtract the value of any cashback or reward, and divide by the number of months in the contract. Two deals with the same headline price can have very different effective monthly costs.

Mid-contract price rises are disclosed on every deal. Where a provider has scheduled rises, we show the new price and the date it starts. Where a provider reserves the right to change prices during your contract, we say so. A deal is only labelled fixed price when the provider has no scheduled rises, no promotional rate that ends mid-contract, and no terms allowing a mid-contract change.

Where a provider says prices may rise but states no amount we don't guess. The effective monthly cost assumes no rise, so it may be lower than you'll actually pay, and the deal can sit higher in the Best value order than a deal whose rise is stated. The deal says both, next to the provider's own wording. Other Ofcom-accredited comparison sites calculate their cost figures on the same basis; the per-deal note is our own addition. The alternative, adding a figure the provider has never stated, would rank its deal on our guess. A provider that raises prices without having stated an amount must give you 30 days' notice and let you leave penalty-free. Where a provider states its annual rise but a listing doesn't carry the schedule, we apply the provider's own figure and mark it on the deal as its stated rise; where that rise falls inside an introductory period we apply it from the end of that period.

Some of our broadband pages show a typical yearly saving of £105. This is how we work it out.

We start with the typical monthly broadband bill reported by households using our exit fee calculator: £35 a month, the median of 2,433 households who used it from 16 May to 31 August 2026. We compare it with the typical effective monthly cost of the better-value half of the broadband deals we list, which was £26.25 a month across 461 deals on 13 September 2026.

The difference is £8.75 a month, or £105 a year. Ofcom's research points the same way: in-contract broadband customers pay £7 to £9 a month less than out-of-contract customers, which is £84 to £108 a year.

A typical saving is not a promise. What you save depends on what you pay now and the deal you choose. We review these figures every quarter.

We don't show a typical saving on our mobile and SIM only pages. Savings there depend on whether you're leaving a phone contract or a SIM only plan, and we don't yet have enough reported mobile bills to base a figure on. Those pages show live figures from their own deal lists instead: the cheapest monthly price, how many deals there are and how many networks offer them. Our community savings total counts broadband switches only.

• Prices are the provider's standard price for new customers paying by Direct Debit, which is how UK broadband providers bill by default. We do not model surcharges for other payment methods.
• Speeds shown are the provider's advertised average speeds. Under UK advertising rules, this is the speed at least half of the provider's customers on that package get during peak evening hours (8pm to 10pm), so it reflects real-world performance rather than a theoretical maximum. Your actual speed still depends on things like your home wiring and distance from the cabinet, which is why providers give you a personalised estimate when you order.

We compare consumer home broadband deals, including full fibre, part fibre, cable and 4G or 5G home broadband, plus bundles with TV or a home phone. A few things are deliberately handled separately:

• Business broadband is excluded from consumer results and has its own page at business broadband deals, where you can compare the business deals available at your address.
• Social tariffs, the discounted packages for people on qualifying benefits, are shown on our dedicated social tariffs page rather than mixed into the main results, and you can check which are available at your address. Our results don't include every provider's social tariff, so every list of them links to Ofcom's full list. Switchity earns no commission on social tariffs; we list them because the people who qualify should know they exist.

We aim to cover a significant share of the UK broadband market, but no comparison site covers every deal from every provider, and you may find offers elsewhere that we do not list. Any UK provider who would like their deals included can contact us at hello@switchity.co.uk and we will work with them and our data platform to add their tariffs on reasonable terms.
