AdBlue repair in Great Dunmow
Also known simply as Dunmow, this historic market town in the Uttlesford district of Essex lies just north of the A120, roughly midway between Bishop's Stortford and Braintree. It stands on the site of a Roman settlement on Stane Street, in the upper valley of the River Chelmer, and is 8 km east of London Stansted Airport. At the 2021 census the built-up area had 10,395 residents and the wider parish 10,630, all within the CM6 postcode district. Neighbouring towns are a moderate drive away rather than on the doorstep: Bishop's Stortford is 13.3 km, Braintree 13.7 km, Sawbridgeworth 16 km, Chelmsford 17.4 km and Saffron Walden 17.8 km. For a van or diesel car based here, most trips to those towns involve a proper run out of Dunmow, and with the town lying just north of the A120, that road is the obvious one to know.
