The 15-minute UK broadband switch playbook (right-size, measure, then lock in a fair deal)

Most UK households overpay for broadband in one of two ways. They buy more speed than they will ever use, or they stay on an old deal while prices creep up. The fix is not guesswork. It is a simple loop: right-size, measure, compare at your address, then switch with confidence.

This guide shows a practical process you can do in one sitting, using free tools from the SearchSwitchSave.com network and UK consumer rules that protect you when you switch. For ongoing updates, see SearchSwitchSave.com industry news.

Step 1: Right-size your speed before you shop

Start by working out what speed you actually need at peak time, not what looks good on an advert. A good estimator should ask about how many people are online at once, what you stream, whether you work from home, gaming, and upload-heavy tasks.

Use this first: RightSpeed.co.uk and its free questionnaire. It gives you a recommended download and upload range, plus a simple explanation you can use when comparing packages.

Why this matters: the cheapest “deal” is often the wrong one if upload is poor, or if you are paying for gigabit you do not need. Right-sizing cuts cost without cutting quality.

Step 2: Measure what you get today (and do it properly)

Before you change anything, measure your current performance so you have a baseline. Run a browser-based test near your router, then repeat on Ethernet (e.g. wired from your laptop or PC to the back of the router) if you can. Do it once at peak time (typically evening) and once in the day.

Use one of these, depending on what you care about:

  • HowFast.uk for a quick, browser-based result with latency under load and jitter.
  • UKSpeedTest.co.uk (Pulse) if you want a clean “download, latency, jitter” view, and you prefer a median headline number.
  • Laggy.uk if your issue is gaming feel, calls stuttering, or general “it feels slow” even when download looks fine.

Tip: if the wired (Ethernet) test is strong but Wi-Fi is weak, your best upgrade might be Wi-Fi setup, not a pricier package. If both are weak, it is time to compare what is available at your address.

Step 3: Compare address-level deals, not generic prices

Broadband availability and pricing are postcode and address specific. The goal is to shortlist 2 to 4 options that match your RightSpeed range, then compare on total cost, contract length, setup fees, and price-rise terms, not just the first month.

Use whichever route suits you:

One crucial rule: for new contracts from 17 January 2025, Ofcom rules require providers to set out any in-contract price rises upfront in pounds and pence, and they prohibit inflation-linked or percentage-based rise terms in new contracts. This makes it easier to compare true cost. See: Ofcom guidance on banning inflation-linked price rises.

Step 4: Switch safely using One Touch Switch (and know your protections)

If you have ever avoided switching because you did not want the hassle, Ofcom’s One Touch Switch process is designed to remove that friction. In most cases, you contact your new provider, they manage the switch, and you receive key information from your current provider (including early termination charges) before you confirm. See: Ofcom: Switching broadband provider.

Two protections to know:

  • No notice-period charges beyond the confirmed switch date: once your new service has been confirmed working, you should not be charged notice-period charges beyond that date. (Ofcom One Touch Switch guidance.)
  • Compensation if things go wrong: providers must compensate you if, for example, you are left without service for more than one working day, or if they miss service or installation appointments, and they must pay within set timeframes. (Ofcom switching guidance.)

Important nuance: if you are switching a bundle (especially where TV services are involved), you may need to cancel parts separately. Ofcom notes this can vary by bundle type.

Step 5: Protect yourself from spring price shocks (without guesswork)

If you are worried about spring price rises, build it into the decision now. Some deals are genuinely fixed for the full term, some include a clearly stated pounds-and-pence rise, and some remain variable. Your job is to choose knowingly.

A practical pattern that works well:

  1. Shortlist deals that match your RightSpeed range. (RightSpeed.co.uk)
  2. Filter out anything with unclear rise language, if budget stability matters more than headline price.
  3. If you want a deeper walk-through of the “switch before April” logic, see: The April Shield: How to Dodge the 2026 Broadband Price Hikes.

MoneyHelper also makes the core point clearly: switching is now simpler, and many households can save by reviewing broadband and phone bills rather than assuming they are already on the best deal. See: MoneyHelper: how to save money on household bills.

Common mistakes that cost people money

  • Comparing monthly price only. Always look at total cost over the term, including setup, delivery, and what the price becomes after promo periods.
  • Ignoring exit fees. If you are mid-contract, compare the early termination charge with the saving you would gain. (See Ofcom switching guidance.)
  • Not checking upload and latency. Video calls, cloud backups, and gaming can be limited by upload, latency, and jitter even when download looks high. (UKSpeedTest.co.uk, Laggy.uk)
  • Assuming every switch is identical. Some bundles need extra care to avoid disruption. (See Ofcom switching guidance.)

The SearchSwitchSave.com toolchain (pick your goal)

If you want one simple “what do I do next” flow, use this:

  1. Find the right speed range: RightSpeed questionnaire.
  2. Measure your current line: HowFast, UKSpeedTest, or Laggy, depending on whether you care about speed, stability, or gaming feel.
  3. Compare deals at your address: SearchSwitchSave.com compare by postcode, then optionally cross-check via FibreSwitch or BroadbandSwitch.
  4. Check real local performance: BroadbandMap.org.uk (postcode-level insights), plus Broadband Insights for how to read the numbers.
  5. Explore the wider domain estate: FBRE.uk lists the network and tool focus, including speed tests, postcode tools, and comparison journeys.

Next step

Do it in this order today: RightSpeed, then a speed test, then an address-level comparison, then switch using One Touch Switch protections if you are happy with the terms. If you want ongoing updates that affect pricing and switching, follow SearchSwitchSave.com industry news.
