Broadband
UK broadband switching explained: fibre types, speeds, and what to ask
A plain-English guide to UK home broadband—FTTC vs FTTP, advertised speeds, contracts, and the questions a doorstep helper might walk through with you before you switch.
Switching broadband in the UK should not require a engineering degree—but the acronyms and speed claims can feel overwhelming. This guide breaks down what most households actually need to know, in the same spirit as a Doorstep Savings helper explaining options at your pace.
Why “fibre” on the label does not tell the whole story
Fibre is used for several different technologies. The two you will see most often are:
- FTTC (fibre to the cabinet) — Fibre runs to the green street cabinet; copper telephone wire completes the journey to your home. It is widely available but speeds drop with distance from the cabinet.
- FTTP (fibre to the premises) — Fibre runs all the way to your home. This is the technology behind many “full fibre” products and typically supports much higher speeds and more stable performance.
When you compare deals, ask whether the service is FTTP or FTTC (or another technology such as cable in some areas). The right choice depends on what is available at your address and how you use the internet.
Download speed, upload speed, and “average” speeds
Providers often advertise an average download speed—commonly measured at peak times for a sample of customers. That is useful for comparison, but your experience still depends on your line, Wi-Fi, and how many devices are active.
Upload speed matters if you:
- Work from home on video calls
- Back up photos or large files to the cloud
- Live-stream or create content
If you mostly browse and stream one TV at a time, a moderate symmetric package may be plenty; if several people are on video at once, headroom on both download and upload helps.
Contracts, price rises, and exit fees
Before you switch, check:
- Minimum contract length and when it ends
- Early termination charges if you leave early
- Introductory pricing versus the price after the discount period
- Whether the provider has published annual price rise rules (often linked to inflation or a fixed percentage—always read the small print)
A doorstep visit can be a good moment to line these dates up on paper so you are not guessing from memory.
Equipment: router, installation, and Wi-Fi
Some deals include a router and engineer installation; others are self-install. If your home has thick walls or an awkward layout, you may want to budget for mesh Wi-Fi or access points—your helper can flag this as a practical question, not a sales pitch.
Questions worth asking any provider
- What technology is available at my postcode (FTTP / FTTC / other)?
- What are the average download and upload speeds for similar lines locally?
- What is the out-of-contract price after any introductory offer?
- Is there a minimum speed guarantee or compensation if speeds fall below a threshold?
- What happens if I need to cancel during the cooling-off period or mid-contract?
