If you're in the UK I would recommend the following:

- Barclaycard for your merchant bank account

- SagePay for the payment gateway

And if you're implementing recurring payments then I'd recommend Recurly.

After much trial and error this is the best combo that I could find.

If you're after something even simpler, try using hosted payment page solution from SagePay.

Make sure you take into account VAT when taking payments in the UK.
