There are numerous bureaux de change in London – often located inside banks, travel agents or Post Offices, as well as at London’s airports and major train stations. Credit and debit (bank) cards – especially Visa and Mastercard, American Express and Diners Club cards – are widely accepted.
Contactless cards are widely used in the UK and many businesses accept them as payment, up to a limit of £30 per transaction. Travellers can use a contactless card instead of an Oyster card when using public transport in London.
Also, There are plenty of cash machines (also known as cashpoints or ATMs) dotted around London.

Power outlets

UK appliances are fitted with three-pin plugs that can be connected to the UK mains supply through wall sockets. Unlike the sockets in many other countries, these have a switch to turn the power supply on and off – make sure you’ve turned it on if you’re trying to charge your appliance!

UK power sockets deliver an average voltage of 230v, although in practice this can be slightly higher.

To charge devices that are compatible with this voltage, simply buy the appropriate adapter from the airport or from high street shops.

If your device runs on a lower voltage, you will also need a converter to stop it from overheating. Even if your country uses lower voltages, remember to check whether your device is dual-voltage (look for the 110-240v notation) before buying a converter.

Medications

According to the UK.gov website, all medication prescriptions and medical items are allowed on board. The traveler must have documents to prove they are required by a medical professional, which can include a prescription. Medicines such as tablets, liquids, inhalers and hypodermic syringes are all allowed on board
