You can't underestimate the importance of a reliable mini cab service. For some, a cab is just something that takes them home late at night, or gives them a ride to the airport when they're off on holiday. For others, a mini cab is a lifeline - a ride to the local shops or to the doctors - and regular customers establish good relationships with the drivers. You may need a mini cab for:

- A night out

- Theatre trips

- The school run

- Visiting the doctor or the hospital

- Helping with supermarket shopping

- Airport transfers

So, what should you look for when you're choosing a taxi service?

Licence

A good mini cab business will be licensed by their local authority. Requirements for licensing can vary, but authorities need to know that the cars used by the taxi company are suitable for carrying passengers, and companies may also have to submit proof of ownership and relevant service details for the vehicles, as well as copies of the driving licences of drivers working for the business. Once licensed, the company should display their licence number on the cab, so check that the company is licensed before you book with them.

Recommendations

Recommendation is often the best way to find a good mini cab service. Find out which services are used regularly by supermarkets and doctor's surgeries, or ask neighbours which companies they would use. You will find that most people have come across a company with very bad or very good service and are happy to tell you who they use.

Cost

If you're planning a long journey, make sure that the firm you choose is willing to agree a cost before you start. Most reliable firms will have set prices for trips to city centres or airports and if you agree this price before you go, you won't get any nasty surprises at the end. For shorter journeys, ask for an estimate and find out whether additional charges apply after a certain time.

If you're going to be using a mini cab service on a regular basis, it makes sense to do a bit of research before you commit to a booking. That way, you can find a service that meets all your needs and is of real use to you.
