How to complain to your broadband provider

When things go wrong, usually Ofcom (the UK telecoms regulator) has your back. Its rules keep providers that are offering unsatisfactory service in check, ensuring automatic compensation, the right to switch away if your issues can't be resolved, and so on. But what if you just can't get any joy from your provider? You'll need to complain. Here's how to go about it.

In this guide...

What can you complain about?

  • Billing issues – These have cropped up en masse in the past, with some providers fined for overcharging customers. If you have been overcharged or just need clarification on your bill, you should contact your provider immediately
  • Faulty equipment – You don't own the equipment supplied to you by your broadband provider. That being the case it is their responsibility to fix and/or replace it when things malfunction
  • Slow broadband speeds – When you sign up to a broadband deal, you will be promised a certain average speed. If what you get is significantly, and constantly, below this and your provider cannot fix it, you can leave your contract without being penalised
  • Connection issues – If your router can’t connect to the internet then it’s time to contact your provider. Most broadband providers will be able to tell you straight away if there’s a known fault in your area and how long it’ll take to fix it. If the fault is just on your line then you might need to book an engineer appointment with your provider
  • Email problems – Most providers offer a free email address or even a few of them with your package. If there are problems with it, they are responsible for fixing them
  • Customer service – When you speak to your provider, you can expect a certain level of service. If it fails to meet this standard, you’re well within your rights to complain about it

Check the small print of your contract

Though tedious, it's almost always a good idea to familiarise yourself somewhat with your broadband contract. That way you can be aware of what your provider's obligations to you – and you to it – actually are.

Check for obvious problems – is it something you can fix?

Just because your internet stops working, don't always assume your provider is at fault. It's not always the case. Sometimes something you have done or are doing may be affecting your connection, so it's best to assume that first before getting on the phone to your provider.

It might be a cliché, but if your internet connection has dropped out, try turning your router off and on again. It's the first thing your provider will ask you to do anyway, so you may as well give it a go before you make the call. Also, it’s always worth checking that all the cables are securely plugged into the right places as this is another simple thing that might just fix the issue.

If your broadband speed is well below that which was promised or what you yourself are used to, before you complain, try relocating your router and checking your settings. Also, if it's a mobile phone, for example, try to eliminate whether it's the phone or your router by checking to see how well other devices connect.

Making initial contact with your provider

A formal complaint is never the way to go initially. Contact your provider, explain your problem, and 99.9% of the time your provider is going to work pretty hard to get it resolved for you. And don't go in angry either – it never helps. Instead, keep calm and explain clearly exactly what the issue is. This will help the customer service team to understand your situation and find the best way to help you.

If you're not a phone call person, you can either email them, or get in touch via social media. Twitter, in our experience, is actually the best place to get your provider's attention if you're struggling via other means. The public nature of Twitter conversations means providers have a powerful reason not to appear to have failed you in some way.

Keep detailed records of conversations

Remember to get the name of the person you spoke to, when you spoke to them and what was said. Do not record the conversation, however. The law states that you have to ask the permission of your provider to do this and they are within their rights to say no.

Ask for written confirmation of changes to your contract

If your contract is about to change in some way as a result of your problem or complaint, make sure your provider sends you all the details of any changes in writing. This will become important further down the line if there are any more problems.

Making a formal complaint

Remember that you can only make a formal complaint if your provider has failed, or is continuing to fail, in resolving your issue. Complaints should never be made right at the outset, rather you will need to give your provider ample opportunity to fix your problem first. You can complain to your provider formally in writing via letter, email, or verbally over the phone and in some cases via live chat.

When complaining in writing, be sure to include your account number and your contact details in your letter or email. The amount of time it will take to get a reply will depend on which provider you’re with and how you decide to get in touch with them. Most providers say they’ll respond to email complaints within five or seven working days, and to letters within 10 working days.

If you don’t know where to start with a formal complaint, you can always use online complaints tool Resolver, which provides guidance and advice as to how to get the best result from your complaint, as well as free forms to use as part of your complaints process. It will also set up a case file for you and help you manage and track the progress of your complaint.

Requesting a deadlock letter

A deadlock letter will be sent to you by your provider if your complaint reaches the point when neither you or your provider can agree on a way to solve it. You can ask your provider for a deadlock letter at any time if you think things aren’t going to get better, but it’s often worth giving them a bit of time to try and resolve your issue.

Contacting the Ombudsman

If you have a deadlock letter, or if your provider hasn’t dealt with your complaint in a satisfactory manner after eight weeks, you can take your complaint to what is known as an Alternative Dispute Resolution (ADR) scheme. There are two ADR schemes that deal with broadband complaints, but you’ll only need to contact the one that your provider belongs to. All broadband providers must be a member of one of these schemes.

The Communications and Internet Services Adjudication Scheme (CISAS) covers Virgin Media, Vodafone, Sky, TalkTalk and NOW Broadband as well as a number of smaller providers. You can submit a claim online, write to CISAS at the Centre for Effective Dispute Resolution, 70 Fleet Street, London EC4Y 1EU, call 020 7520 3814 or email cisas@cedr.com.

Ombudsman Services covers BT, EE, and Plusnet among others. You can complain to Ombudsman Services online, send an email to enquiry@ombudsman-services.org, write to Ombudsman Services: Communications, PO Box 730, Warrington WA4 6WU or call 0330 440 1614.
