1) Your 5‑minute broadband audit

Start with two simple checks:

  • Right‑size your needs in 60 seconds with the free questionnaire at RightSpeed.co.uk. You’ll get a sensible speed range based on people, devices, streaming, gaming and home‑working.
  • Test your actual line with a wired check on HowFast.uk at a busy time. Run it near the router, then compare with Wi‑Fi to spot bottlenecks.

Tip: If your measured peak‑time download is consistently below roughly 70% of your plan’s rate, you’re either on the wrong package or with the wrong provider. Do the quick maths and move on to a better fit.

2) Pick the right speed for your home

Don’t overbuy headline speeds you’ll never use. Use this practical bracket guide, then fine‑tune with RightSpeed:

  • 30 to 60 Mbps – solo users or couples, HD streaming, browsing, light video calls.
  • 100 to 200 Mbps – families or house‑shares with multiple HD streams and regular calls.
  • 300 to 500 Mbps – busy homes with 4K streaming, cloud backups, console downloads.
  • 900 Mbps and above – creators, multi‑room 4K, very heavy download/upload households.

Upload matters if you do lots of video calls, cloud sync or content creation. Some full‑fibre packages offer higher or even symmetrical uploads. If that fits your life, prioritise it when you compare.

Need a deeper dive on real‑world versus advertised speeds and why they differ? See our guide on Broadband speed demystified and the UK Broadband Speed Guide.

3) Compare deals the smart way

Prices, speeds and technologies vary by postcode. For a fair like‑for‑like comparison, use a quick “deal maths” check:

Total first‑year cost = (monthly price × 12) + setup or delivery fees − any bill credit or voucher that clearly reduces what you pay. If your contract states a pound‑and‑pence rise inside the first 12 months, include it.

Then sort results by total first‑year cost, not just headline monthly price. Our Broadband Deals page shows clear totals, contract lengths, and any price‑rise policy in plain English.

Good to know for 2025: new contracts set out any mid‑term increase in pounds and pence at sign‑up, so you can budget with confidence. You can also switch using a simple, provider‑led process. More on that below.

4) Switching in 5 steps

  1. Check your contract status. If you’re out of term, you can usually switch with no exit fee. If you’re still in term, note any charges versus the savings of moving now.
  2. Run a postcode search on Broadband Deals and shortlist at least three offers that meet your speed and contract preferences.
  3. Pick, order, and let the new provider handle the handover. The modern switching process is designed to minimise downtime. Cross‑network moves may need an engineer visit, so book a date that suits you.
  4. Plug in the new router and run a wired check on HowFast.uk.
  5. Return old kit using the prepaid bag to avoid charges.

5) Renters: easy, flexible options

Renting should never mean second‑rate internet. You’ve got three clean routes:

  • Rolling 1‑month plans for short lets and uncertain timelines.
  • 12‑month plans for lower monthly prices without a long tie‑in.
  • Zero‑drill 4G or 5G home broadband you can plug in and take with you.

If a fixed install needs permission, we include a landlord‑friendly email template. Get it and browse renter‑friendly offers at Broadband for Renters.

Unsure what your flat needs? Size it with RightSpeed, then sanity‑check your current connection on HowFast.uk before you switch.

6) Wi‑Fi quick wins before you switch

Half of “slow broadband” is really in‑home Wi‑Fi. Try these fixes first:

  • Move the router into the open, off the floor, away from metal objects and microwaves.
  • Use the right band: 5 GHz for speed near the router, 2.4 GHz for range through walls.
  • Go wired for consoles and desktops that need stability and low latency.
  • Add mesh for large or older homes where a single router cannot cover every room.

7) If speeds fall short: what to do

  1. Gather evidence. Run several wired tests on HowFast.uk at different times. Note dates, times and results.
  2. Fix what you can with the Wi‑Fi tips above. Compare wired versus Wi‑Fi results.
  3. Check your contract info. Many packages include realistic speed ranges and minimums. If your service persistently sits below that, you may be allowed to exit or get a remedy.
  4. Switch cleanly to a package that matches your needs. Start here: find better broadband deals.

FAQs

Will my price go up mid‑contract in 2025?

New contracts set out any change in pounds and pence at the point of sale, so you can see it in advance. Always read the pricing line in your order summary.

How does switching work now?

You choose a new deal and the gaining provider coordinates the handover. Many moves happen with only brief downtime. Cross‑network installs may need an engineer visit.

What speeds do most households need?

Light users are comfortable at 35 to 50 Mbps. Busy homes and shared flats should consider 100 Mbps or faster. Upload speed matters for calls, cloud sync and sharing.

What if I rent?

Look for 1‑month or 12‑month terms, or choose a plug‑in 4G or 5G hub to avoid drilling. See Broadband for Renters for permission tips and flexible options.

How do I choose a trustworthy provider?

Run our trust checklist before you order and prefer clear, plain‑English pricing with a fair service policy.
