The ICO (Information Commissioner's Office) is the regulatory authority in the UK that deals with this for UK companies and individuals... so the following is the advice that they are giving for companies who recieve these requests. They also give advice to individuals who want to make them
The advice below is for companies who are facing a request

-------------------------
How long do we have to comply?
You must act on the subject access request without undue delay and at the latest within one month of receipt.
You should calculate the time limit from the day after you receive the request (whether the day after is a working day or not) until the corresponding calendar date in the next month.
Example
An organisation receives a request on 3 September. The time limit will start from the next day (4 September). This gives the organisation until 4 October to comply with the request.
If this is not possible because the following month is shorter (and there is no corresponding calendar date), the date for response is the last day of the following month.
If the corresponding date falls on a weekend or a public holiday, you have until the next working day to respond.
This means that the exact number of days you have to comply with a request varies, depending on the month in which the request was made.
Can we extend the time for a response?
You can extend the time to respond by a further two months if the request is complex or you have received a number of requests from the individual. You must let the individual know without undue delay and within one month of receiving their request and explain why the extension is necessary.
However, it is the ICO's view that it is unlikely to be reasonable to extend the time limit if:
- it is manifestly unfounded or excessive;
- an exemption applies; or
- you are requesting proof of identity before considering the request.
