Do you regularly require a number of series from a range of our economic releases featured in the Time Series Data service ? Or do you prefer to receive data on disk instead of via our website ? Our tailored service can provide you with updated data each time one of the series you need is updated. We can provide the data in a choice of formats, and you can collect your selection from our website or we can send it to you on disk by fax or in Excel spreadsheet format via email attachment.

Via the website or on disk, we can provide data in plain text file or Navidata format. Navidata is free-of-charge in-house software that allows you to make tables and graphs - and it's easier to import data into a spreadsheet package like Excel from Navidata^®. Download the Navidata^® software.

The cost of this service is as follows (prices include postage and packing where appropriate but exclude V.A.T.) -

• Complete main release on floppy disk - £10 per disk (so £120 per year for a monthly subscription via disk)
• Tailored data - £5 per time series (minimum 10 series) + £30 per half hour fee to cover initial set up costs.

Each of our time series has a four-letter identifying code which you can see in our publications and in text file listings in our Contents area. For example - CHAW is the four letter identifier for our series RPI all items (January 1987 = 100) index.

If you want to use this service, please send us a list of the main releases or four-letter-identifiers that you require, along with choice of format and an invoicing address for billing purposes. Send your requirements, or any requests for further information about the tailored service , by email to statbase@statistics.gov.uk, or telephone 020 7533 5675.
