FTTP, FTTC, and ADSL: What Does Your Connection Actually Look Like?
Before you can judge whether a broadband deal is worth paying for, it helps to understand what kind of physical connection is running into your home. In 2026, the UK has three main technologies still in active use, and the differences between them are significant.
ADSL (Asymmetric Digital Subscriber Line) uses the old copper telephone network. Speeds typically top out at around 10–24 Mbps download and are heavily affected by how far your property sits from the local telephone exchange. If you live in a rural area and still have ADSL, you may be getting speeds well below what is technically possible even on copper. Ofcom’s Connected Nations reports have consistently shown that a meaningful portion of UK premises — particularly in rural Scotland, Wales, and parts of Northern England — still rely on this technology.
FTTC (Fibre to the Cabinet) is what most people mean when a provider advertises “fibre” without being specific. The fibre cable runs from the exchange to a green street cabinet, and then copper wiring carries the signal the rest of the way to your front door. This last stretch of copper is what limits FTTC speeds — typically between 30 and 80 Mbps download, depending on the length and condition of the copper line. Openreach, which manages the majority of the UK’s broadband infrastructure, has described FTTC as a transitional technology.
FTTP (Fibre to the Premises) — also called full-fibre — is what all the current UK infrastructure investment is pointed toward. The fibre cable runs directly into your home, meaning there is no copper bottleneck. Speeds are symmetrical or near-symmetrical, far more consistent, and far less affected by distance or network congestion. Openreach, along with alternative network operators (altnets) such as CityFibre, Hyperoptic, Netomnia, and others, have been expanding FTTP coverage at pace. As of 2026, FTTP is available to roughly two thirds of UK premises, though take-up rates still lag behind availability.
What 100, 330, and 900 Mbps Actually Means in a Real Home
Speed tiers can sound impressive on paper but mean little without context. Here is what each commonly available tier translates to in everyday household use:
| Speed tier | Typical use case | Simultaneous streams / devices |
|---|---|---|
| ~100 Mbps | A couple or small family — 4K streaming, video calls, general browsing | 3–5 devices without noticeable slowdown |
| ~330 Mbps | Busy household with multiple streamers, remote workers, and gamers | 8–12 devices comfortably |
| ~900 Mbps–1 Gbps | Large households, home offices handling large file transfers, or simply future-proofing | 20+ devices; near-instant large downloads |
A 4K Netflix stream uses roughly 15–25 Mbps. A video call on Teams or Zoom rarely exceeds 3–5 Mbps per person. A large game download on Steam — say, 80 GB — takes around 18 minutes on a 600 Mbps connection and over two hours on a 10 Mbps ADSL line. For most households of two to four people, a 100–330 Mbps full-fibre connection is more than adequate. Gigabit speeds become genuinely useful if you regularly move very large files, run network-attached storage, or have six or more people streaming simultaneously in 4K.
Why Advertised Speeds Are Sometimes Optimistic
Under Ofcom’s rules, which were tightened following the Advertising Standards Authority’s guidance, ISPs must advertise the speed that at least 50% of customers in the relevant product can actually achieve during peak hours (8pm–10pm). This is called the “median average speed” rather than the theoretical maximum. In practice, this means two things worth knowing:
- The headline figure is a midpoint, not a floor. Half of customers on that product could be getting less than the advertised figure at peak times.
- Your individual speed depends on your router, internal wiring, and the quality of the fibre installation. A poorly positioned router or an old internal master socket can reduce your effective speeds considerably, even on a full-fibre connection.
You are also entitled, under rules introduced by Ofcom, to exit your contract without penalty if your actual speed consistently falls below the Minimum Guaranteed Access Line Speed that your provider must tell you about before you sign up. Keep a record of your speeds using a tool such as Ofcom’s own broadband checker or Fast.com, and note the times you tested. This evidence is useful if you need to escalate a complaint.
It is also worth noting that Wi-Fi is frequently the limiting factor, not the broadband connection itself. Plugging a laptop directly into your router via an Ethernet cable is the only reliable way to test your actual line speed. If the wired speed is fine but Wi-Fi is poor, the problem is your router placement or hardware, not your ISP.
The Majors vs the Smaller ISPs: Is There a Real Difference?
BT, Sky, and Virgin Media are the three largest broadband providers in the UK by customer number. They have advantages in terms of name recognition, widespread retail presence (you can walk into a BT Shop or discuss Virgin Media at a Virgin store), and large customer service operations. Virgin Media runs its own cable network, which means its infrastructure is separate from Openreach and tends to perform well in urban areas — though it remains FTTC-equivalent in architecture for many customers rather than true FTTP.
However, larger does not automatically mean better. Ofcom’s annual complaints data consistently shows that some of the major providers attract more complaints per 100,000 customers than smaller competitors. Response times and issue resolution can vary significantly.
Smaller ISPs — sometimes called altnets or independent providers — have grown considerably in the UK market. Rebel Internet is one example, operating over full-fibre infrastructure and targeting customers who want straightforward pricing without lengthy contracts or throttling. Products such as the Rebel 330 at £45 per month and the Rebel 1000 at £55 per month offer mid-range and near-gigabit full-fibre respectively, with pricing that is relatively transparent compared to the introductory-rate-then-price-hike model common among the major providers.
When comparing a smaller ISP with a major provider, consider:
- Contract length: Some smaller ISPs offer rolling monthly contracts; majors often require 18–24 months at the promotional rate.
- Mid-contract price rises: Check whether the provider is permitted to increase your monthly cost in line with inflation (CPI or RPI) plus a fixed percentage. This has been a point of contention and regulatory scrutiny in the UK.
- Network redundancy: Larger operators generally have more engineering resource for fault repair, which can matter in a service outage.
- Customer service channel: Some smaller ISPs are UK-based and offer direct telephone or chat support without long queues; this is not guaranteed, but worth checking reviews on Trustpilot or the ISPreview forums.
How to Complain If Something Goes Wrong
If your broadband service is not working as agreed, you have a clear process to follow in the UK:
- Raise a formal complaint directly with your provider. This must be in writing (email is fine) and should reference the specific problem, when it started, and what you want as a resolution. Keep a copy.
- Allow eight weeks for resolution. Under Ofcom’s rules, if your complaint is unresolved after eight weeks, or if the provider issues a “deadlock letter” earlier, you can escalate to an approved Alternative Dispute Resolution (ADR) scheme.
- Go to the ADR scheme. Most UK broadband providers are members of either CISAS (Communications and Internet Services Adjudication Scheme) or Ombudsman Services: Communications. The process is free for consumers. You can find which scheme your provider uses on Ofcom’s website.
- Contact Ofcom directly if needed. Ofcom does not handle individual complaints but does investigate systemic problems, and reporting to them helps build the regulatory picture. You can file a report at ofcom.org.uk.
If your speed has fallen below the Minimum Guaranteed Access Line Speed agreed at the point of sale, and your provider has had a reasonable period to fix the problem (typically 30 days), you have the legal right to exit your contract without paying an early termination charge.
Practical Checklist Before You Switch
Switching broadband providers in the UK has been made simpler by the One Touch Switching (OTS) process introduced by Ofcom, which means you can in most cases initiate a switch via your new provider rather than having to cancel separately with your old one. Before you commit, run through the following:
- Check whether your address has FTTP availability using the Openreach checker or the altnet’s own postcode tool. Availability in the street does not always mean availability at your specific property.
- Confirm the contract length and any mid-contract price rise clauses in writing.
- Ask about installation — full-fibre typically requires an engineer visit and a small amount of internal wiring work. This is usually free but worth confirming.
- If you use a landline phone, check whether it will move to a Voice over IP (VoIP) service as part of the switch. BT is migrating all copper phone lines to digital voice by the end of 2027, and this affects how phone calls are made, and whether your existing handset will work.
- Note your current contract end date to avoid paying two sets of bills simultaneously or incurring exit fees.
Full-fibre broadband in 2026 is no longer a premium luxury — it is increasingly the standard infrastructure for reliable home connectivity. Whether you opt for a major provider or a smaller ISP such as Rebel Internet, the most important thing is to compare on actual delivered speeds, contract terms, and what recourse you have if things go wrong, rather than being swayed by headline prices or marketing language. A slightly higher monthly cost on a fair, transparent contract will almost always represent better value than a cheap introductory rate that rises sharply after twelve months.
