Service availability

The OS MasterMap service is available at all times. From time to time the service may need to be taken down to implement new releases of the service, or for maintenance reasons. As far as possible we schedule these outages outside of office hours and aim to provide you with at least five working days notice on our website.

Ordnance Survey will endeavour to respond to the following actions within the timescales set out below. We will:

Expected delivery times

Data ordered for collection from the OS MasterMap FTP server will generally be available 4 calendar days from receipt and acknowledgement of a fully completed and accepted order. Any order for data over 400 Mb will be delivered via physical media (DVD or CD) and not via the FTP server due to threshold limits in place on the server. If this situation arises, the user is notified by email.

We will advise the person who placed the order by email when the data is available for collection from our FTP server. Instructions for the collection of the data placed on our FTP server, including the URL address, will be included in the email.

Data ordered for delivery on media (DVD or CD) will generally be dispatched 4 calendar days from receipt and acknowledgement of a fully completed and accepted order. This may be exceeded for large orders, for instance, orders for Great Britain, England, Scotland, or Wales. The data will be dispatched by commercial next-day delivery at no extra charge.

You may ask for alternative delivery arrangements for which an extra charge may be made and any orders requesting delivery outside of the EU may attract a delivery surcharge. Please contact us (see link below) to discuss your requirements.

Unless we agree differently in writing, the dates we provide for delivering the goods or services will be approximate only, so the time of delivery will not form part of the contract. However, we will do all that we reasonably can to meet delivery dates and avoid unnecessary delay. If you do not take delivery of the goods or services when they are due, or fail to provide any information we need to deliver the goods on the due date, we may give you written notice and store or arrange for storage of the goods. You will then be responsible for the goods and must pay us all reasonable costs and related expenses, including storage and insurance charges (if any).
