About Us

The Agency was started in 1987 when Julie Frost, an RVN, set up to support practices in Northern England – however geographical coverage soon outgrew the name, and the Agency helps practices nationally. It is now led by Jane Threlfall, who joined the Agency in 2007 and has grown an extensive knowledge of practices nationally.


I've always found Northern locums very friendly and useful since I started using them back in 2008. They have always been easy to talk to, and have helped me get plenty of work so that I've never needed to use other locum agencies. They're also happy to give advice, or point me in the right direction, on practices, daily rates, tax, accountants and all the other information I've needed over the years. I would highly recommend them.

I have been registered with the northern locum agency for nearly 30 years now and throughout that time have found them to be both very professional and most importantly to have that personal touch .They have always tried to provide me with work at practices that suit both mine and the practices needs. I will continue to use them for all future locum work.

I have worked through the northern Locum agency since they started and have always had great service matching my needs with practice needs I have received good information about the practices and I like the fact I speak directly to the practices and then have 'from the horse's mouth' info rather than second or third hand I look forward to continuing to work with the agency in the future.

I used The Northern Locum Agency as a locum for the first time in 1995 when I needed work after a back operation. The Agency found me work immediately and within 2 days I was working in a lovely practice . The Agency matched me with practices and took feedback to make sure both parties were happy. This ensured good service for all concerned. Since then I have used the agency to get locums and from the other side of the fence I found the service of high quality and professional. For the last seven years I have been a locum again and have had a lot of work from the Northern Locum Agency. They are always pleasant efficient and highly professional and I know the practice I will be going to will be a nice and pleasant one to work in. Thank you all at NLA.
