South Mimms is situated at the busy roundabout between the M25 and A1(M). It has supreme local access, and various refurbishments mean it is pretty modern. They claim to offer special facilities for truckers.

Trivia and History

The coffee lounge in the large building.

The services were opened by Margaret Thatcher on 6 June 1987 but they had to be rebuilt following a large fire on the 13 August 1998 caused by an unattended frying pan in Julie's Pantry. This makes them both the oldest and, until recently, the newest services on the M25. The temporary building which was used whilst the services were being re-built was then sold in an online auction.

The services' site comprises of several things, including a works unit. The only sensible route between the motorways and the village of South Mimms is to leave at the junction and drive through the services, where there is a link road to the village. This feature is pretty much exclusive to the services, and similarly they are the only service area connected to the national cycle routes.

In 1987 Fortes wanted to host a charity family fun day at the services, but were forced to cancel it following a complaint from the Ministry of Transport.

BP operate the filling station for cars here, but not for HGVs.

The hotel here is currently undergoing refurbishment and is due to reopen in early 2016 branded as Ramada. Government policy ought to have refused to allow the hotel to be constructed in 1990 as the land was needed to extend the services, but an exception was made because there was no-where else to build it.

A new trial brand called Ed's Easy Diner opened a diner here on Monday 4 April 2016 in its own building between the main building and the hotel and is the first Ed's Easy Diner at a Welcome Break site. This was originally going to be a Frankie & Benny's but was changed at the last moment. The first motorway Pret a Manager opened on Wednesday 24 August 2016.


The services are off a busy roundabout, however its location presents an even bigger problem for the police. Over time, several illegal activities have been uncovered here, largely due to its location being where two major routes cross, one coming out of London (where South Mimms is the first service area you'd pass) and one heading towards the Channel Ports.

National Cycle Network route 12, also known as the Great North Way, runs from Hadley Wood to Hatfield via the services, and then it continues towards the North East.

In the Public Eye

The services were mentioned in Ian Sinclair's book 'London Orbital', which came to the conclusion that it was dire and in need of a refurbishment, with traffic queueing to leave the site and join the main junction. A few weeks later, he said things had improved. They also starred several times in Sky's 'Brainiac: Science Abuse' and 'EastEnders', and Robbie Williams has sang in the car park.

Roger Green wrote a book on the services titled 'Destination Nowhere: A South Mimms Motorway Service Station Diary'.

The services are on the site of an old truckstop known as the Beacon Café. They were originally owned by BP who already owned land there, and then leased the site out to Welcome Break.

Survey Results

In May 2012 and August 2011, Visit England rated the services as 4 stars.

Lord Adonis (Secretary of State for Transport) wasn't impressed by the services when he visited in September 2009, as the toilets were closed throughout his visit and there was a lot of confusion.

In 2007 and again in 2008, South Mimms won a five star loo award. In 2006 it received four stars, and in 2005 five stars.
