In the peak hours of arrival, the taxi queue at Paddington (connecting for the Heathrow Express) can be quite sizable. Don't forget that there is a taxi share service that runs from the station so you can get to where you are going and save money if you share a taxi. London is split into different zones and there should be an agent at the station to help you.
For wheelchair users, simply riding on a double decker bus is an excellent and cheap alternative to a special disabled tour. If you learn the routes and get a day pass, you can ride anywhere.
Additionally, in many taxis, you can just wheel in and go. The underground has many wheelchair-friendly stations and links to airports and the Chunnel, if you want a new and exciting way to explore the continent!
Contact any tourist info booth in London for details, or ask at the stations.

It may not always be the fastest (most times it is) but it will be enjoyable - the drivers know where they are going and you usually only have to tell them the name of the destination. Fares are regulated, metered and in front of you, they can go through places public transport never gets to go, allowing you to discover areas you never knew existed. Usually drivers very talkative when spoken to, will often provide you with insights to the country, city, people, along with their historical, social knowledge of the city, provides an interesting journey in the comfort of your own space at a reasonable cost.
