FAQs

How soon will I get the dataset?

We will setup your account, generate a dataset and provide your initial CSV and secure download link on the same day as payment.

How are datasets delivered?

One-off products without updates are delivered via email as a CSV. Annual subscribers with real-time updates receive a permanent secure download link which will always return the latest dataset in CSV format. This can be integrated into your own software if needed.

Can I cancel a purchase?

A one-off purchase can be cancelled at any time prior to delivery of the dataset, but not afterwards. An annual subscription can be cancelled at any time, but the year one fee cannot be refunded after delivery and in the case of a monthly payment model a minimum of 12 monthly payments must be completed. After cancellation of a subscription, you're welcome to continue using your dataset without updates.

How are May elections handled?

We aim to update any council mergers, boundary changes and newly elected councillors within a week of May elections. Email addresses and roles are added as they become available. Typically, councils (and we) have everything finalised by the end of May.

Can I share the dataset with other people?

Your licence covers usage within your organisation only. If you wish to purchase a broader licence, please get in touch by email above.

When is my renewal payment due?

Annual payments are due on the anniversary of the initial payment.

Should I have concerns over data protection?

No more so than when handling any personal data, such as that of staff or volunteers. You will need to register with the ICO and follow normal data protection procedures regarding any purchased dataset.

What are your data protection processes?

All personal data has been collected in accordance with the Data Protection Act 2018 (UK-GDPR), incorporating measures for transparency, purpose limitation, data minimisation, accuracy, storage limitation, integrity and confidentiality, and accountability.

Why has the pricing structure changed?

From May 2025, we've begun offering new and more comprehensive data fields. We've come up with the new pricing structure to try to accommodate most client's needs. If you need something different, do get in touch.

About Council Data UK

Backstory

I'm Jon Lawson. I launched Open Council Data UK in 2016 to track the ebbs and flows of local authority representatives.
Over the years I've had many requests for additional services and in 2023 I established CDUK to provide premium datasets and services.

What does it involve?

We collect and maintain an archive of all UK councillors every year following the May elections. This dataset is provided under a Public Domain license and stretches back to 2016. As premium services, we also collect and maintain contact details and committee and leadership roles, including bi-weekly updates for new vacancies, by-elections, defections and suspensions, as well as periodic checking and validation processes. Prior to the May elections, details of any council mergers and boundary changes are fed into the database in preparation for the big May election update.
