With millions of customers and huge sums of money to invest in infrastructure, major players BT, TalkTalk, Sky, Virgin Media and Plusnet dominate the UK broadband market.
But that's not to say that biggest is always best. Smaller providers have a lot to offer too, and, for reasons we'll look at here, may be more apt for your needs than their larger rivals.
In this section we take a look the major pros and cons of choosing a smaller provider to help you make the best possible buying decision.
Why do some people choose small broadband providers? We outline the main reasons below.
1. Better customer service
Disappointing levels of customer support were, for many years, a fact of life in the broadband industry. Things have improved a lot since then.
But it's still the case that major providers often don't provide the kind of customer care you'd expect from companies with such large resources at their disposal.
Conversely, small broadband providers perform much better than you might think.
One of the reasons small broadband providers often give better customer support is down to the fact that because they have fewer subscribers, they can prioritise those they have and give a more personal service.
But it's also likely that smaller providers have identified customer support as a way to score points over larger providers with whom they may otherwise struggle to compete. And for that reason, small broadband providers make looking after customers more of a priority.
2. Flexible service of the sort that larger providers don't offer
Smaller broadband providers often carve out a niche with a specialised service that simply isn't available with bigger broadband suppliers, whose packages are much more tailored towards the mass market.
3. You're not paying for sweeteners you may feel you don't need
Small providers usually offer a stripped-down service, largely focused on broadband and calls.
That means that, unlike with some bigger broadband suppliers, you're not paying a higher monthly premium that includes the cost of 'free' services such as priority ticket booking, sports channels or subsidised movie downloads.
4. Keen prices
Direct Save Telecom touts itself as offering the UK's cheapest line rental. If you pay a year in advance, it works out to be cheaper than some providers.
5. Satellite broadband
Satellite broadband, which enables you to get online anywhere in the world irrespective of coverage or network infrastructure, is a service solely offered by smaller providers.
For some people, when it comes to broadband providers, big is best. Below, we look at what larger providers can offer you over smaller ones.
1. Fastest speeds in the UK are exclusive to larger providers
If you want the UK's very fastest speeds, such as Virgin Media's high-end 200Mbps service or the limited-availability BT Infinity 330Mbps product, you'll need to sign up for a larger carrier.
Although some smaller carriers use BT's fibre infrastructure, which enables them to offer speeds of up to 76Mbps, the fastest speeds that BT can offer are only available to BT customers.
2. There's less scope to bundle together multiple services and save money
Sign up for a larger provider and you can bundle your TV with your broadband, home phone and mobile phone, and you'll pay less for each service than if you signed up for them from individual providers.
Small broadband providers' range of services is much more limited, however, so there's less chance to make those sort of savings.
3. Smaller providers haven't got the financial muscle to offer much in the way of sweeteners
As detailed above, if you sign up with a small broadband provider, you shouldn't expect incentives, such as EE's FilmClub or free BT Sport with BT.
You're also less likely to get money-off introductory periods and free vouchers when you sign up, both of which are common promotions used by large providers.
