How to use the free complaints tool

Complaining isn't always easy – companies can ignore you or try to scare you off with legalese. Yet you can use free online tool Resolver* to quickly file and track a complaint – it helps you draft a letter, send it, monitor replies and then escalate it to an ombudsman or complaints body if it's not sorted.

It's been over five years since we partnered with Resolver, and we've added the tool to many of our guides, marrying our campaigning know-how with its technology. Here's how it works.

Which companies can I use Resolver to complain to? You can raise pretty much any kind of complaint with over 30,000 firms and public bodies, including shops, restaurants, energy and telecoms firms, banks and insurance providers (find out more below).

For four of our biggest reclaim guides – Flight delay compensationExperian CreditExpert ID fraud insurance refundReclaim packaged bank account fees and Reclaim payday loans for free we've specially modified Resolver with bespoke MoneySavingExpert letters.

How do I complain if the company I want to complain about isn't included? How do I complain if the company I want to complain about isn't included? It's worth noting while Resolver includes a huge number of firms, it won't include them all. If a company's not listed, you can ask Resolver to add it via a form on its website – but also see our How to complain guide for other options.

Is it any good? We think so – we've partnered with it for years and have had 100s of success stories from MoneySavers, such as the ones below (we'd love to hear what you think too – join the Resolver forum discussion and let us know):

We got back £3,300 from British Airways for our delayed flight to the USA recently – €600 per person. Thank you so much for the direction to use the Resolver website. So quick and easy.

It's not perfect though. Sometimes companies will refuse to engage with complaints sent via Resolver, which can delay the process of getting a response. 

How can it have template letters for every single eventuality? The vast majority of complaints are actually about very similar subjects, though the actual issue can differ by sector. So, if you've got a problem, first select the company you want to complain about, then you will see a list of initial options.

For example, if you're making a complaint about your gas or electricity supply to an energy firm, your choices will include:

  • Account details problem (including address changes)
  • Billing issue
  • Change of tariff problem
  • Complaint handling issue
  • Customer service issue
  • Debt related problem
  • Direct debit problem
  • Final bill issue
  • Installation or engineer visit problem
  • Meter reading problem
  • Smart meter issue
  • Switching supplier problem
  • Refund or credit issue
  • Sales and marketing issue

If you select 'complaint handling issue', for example, you will then be asked to select England, Scotland, Wales or Northern Ireland and you will be given your rights relevant to where you live. 

Press the 'start your case now' button and you will be asked to fill in your details, explain what happened, how you were affected and what resolution you want, and to attach any 'supporting documents' like receipts or tickets.

You'll then be asked to create a free Resolver account so you can track your complaints. The letter is then drafted for you and, in many cases, once you've checked it over and made any changes you want, you just click for it to be sent.

OK, I like the sound of that, but how many template letters does it have? In total, Resolver has over 70,000 variants of template letter, which have been written by the Resolver team and checked by its lawyers.

What happens if my complaint's rejected? One advantage of Resolver is that if your complaint's initially rejected, it'll help you escalate it – within the company first, and then, if necessary, to an ombudsman or regulator.

Several ombudsmen, regulators and other complaints bodies accept submissions directly via Resolver, so you won't have to use their forms as you can fill in a Resolver template.

These include well-known organisations such as...

  • Centre for Effective Dispute Resolution
  • Consumer Dispute Resolution Limited
  • Gambling Commission
  • Financial Ombudsman Service
  • Furniture Ombudsman
  • Ombudsman Services
  • Transport Focus

Can I complain to the company in question over the phone? Yes, phoning the firm in question may be best if you think you've got a straightforward complaint, but remember you may be charged for the call. If you do decide to call, there's a template you can use in the online tool to note down the details of your call and add them to your case file.

Is Resolver effectively a claims management company? No, it's not – firstly, because it's free, and secondly, because while it will guide you, you're in charge of your complaint and responsible for checking it before it's made.

How many cases actually end up being successfully resolved? It's hard to put an exact figure on it, as many users don't log back in to officially close their case, even if they're successful and happy with the outcome.

However, to give an estimate, Resolver analysed 91,000 cases in detail and found 68% had reached a positive outcome, with the users' issues being resolved.

What happens if my complaint isn't resolved after being escalated to an ombudsman? Unfortunately, if it has been deemed your complaint isn't fair, you may have little choice other than to accept the situation. If you want to continue to pursue it, often the final recourse is to take it to court, which is a serious undertaking. See more information about this in our Small claims court guide. 

While Resolver can't help you with this process (yet), having used Resolver can be a real advantage, as it'll give you a complete record of all the correspondence related to your case.

If it's all free, how does Resolver make money? Resolver's entirely free to use but makes money through it's Resolver for Business platform, where it uses its expertise to help organisations build automated complaints systems. The aim of this is to help them keep customers and reduce the cost of dealing with complaints.

Resolver uses its insight aggregated, anonymous data to help organisations improve their services, but it NEVER uses any personal details.

Resolver may also promote partners/services on its website as stated in its privacy policy.
