As an AI, I don't have the capability to provide real-time, dynamic, or proprietary information such as current body leasing rates for Angular and .NET professionals in the UK. The rates for these services can vary greatly depending on the specific skills and experience level required, the length and nature of the project, and the terms of the contract. Furthermore, individual companies may not publicly disclose their rate cards, and the information may be subject to negotiation or subject to change over time.

As of my training cut-off in September 2021, I can share some general information:

1. In the UK, contractor rates can vary widely. A mid-level .NET or Angular developer might command rates in the range of £300 - £500 per day in London, with rates possibly being somewhat lower in other regions or cities. Senior developers or specialists might command higher rates, possibly £500 - £800 per day or more.

2. London generally has higher contractor rates than other parts of the UK, reflecting the higher cost of living and higher demand for tech skills in the capital. Other major tech hubs like Manchester, Birmingham, Leeds, or Edinburgh may also have higher-than-average rates.

3. Contract rates can also vary by sector, with financial services often willing to pay premium rates for specialist skills.

For the most accurate and up-to-date information, you'd need to contact staffing agencies or body leasing companies directly, or consult industry surveys or reports. Remember that contractor rates are often negotiable and may vary greatly depending on many factors.
