Thanks, that's useful.
This is a PO Box rather than a physical location. Like many insurance policies operated under a bank's name, Lloyds TSB Car Insurance is underwritten by a third party, in this case Churchill Insurance. This information is given at:
http://www.lloydstsb.com/insurance/car/car_insurance.aspA search of our database for Churchill reveals no Ipswich (01473) numbers. However, putting
churchill insurance ipswich returns a number of links to pages which give the address and phone:
Churchill Ltd
31 Princes Street
Ipswich
Suffolk
IP1 1PU
Tel: (01473) 546700
This page gives the same address with telephone (01473) 345500.
Be aware that these numbers could be the general office switchboard and therefore are only likely to be available between normal office hours such as 9am to 5pm. It is possible that they may have an option to be put through to customer services out of hours, so don't necessarily discount them.
As you say, there is an alternative of 0800 032 9450 listed as verified alongside the 0845 number. If calling from a mobile, so-called "freephone" numbers (0800/0808/0500) need not be an issue as there are a number of dial through providers around, eg 020 0222 0900. Ring the number, then when it answers it will prompt you for the destination number. As it's a geographic number, you will be billed as a geographic call.
