Barnet is a borough on a hill, and the hill decides the plumbing. Chipping Barnet’s High Street is 427 feet above sea level, Totteridge and Mill Hill sit on ridges of their own, and the mains pressure at the top is not the pressure in the Dollis valley at Whetstone or down at Hendon. The Victorian terraces that followed the 1872 railway to High Barnet and New Barnet, the interwar semis of Whetstone, Friern Barnet and Finchley, the large houses of Totteridge, Arkley and Hampstead Garden Suburb with their plant rooms and long pipe runs, and the new flats at Colindale and Brent Cross each have a different stopcock, a different pipe and a different fault.
Vantage Plumbing and Heating covers Barnet from Stevenage, straight down the A1. We are Gas Safe registered under 956889, our vans carry the fittings that solve most call outs on the first visit, and if water is coming through the ceiling right now, ring us and we will talk you to the stopcock while an engineer is already on the road.

Barnet is the one borough we work in where the water company changes street by street. Affinity Water supplies the north and publishes a figure for each zone: Cockfosters, New Barnet and Whetstone about 271 mg/l calcium carbonate, Finchley about 275 mg/l, High Barnet, Arkley and Totteridge about 295 mg/l, Edgware about 310 mg/l and Mill Hill about 352 mg/l. Thames Water supplies the south: Hendon and Golders Green about 269 mg/l, and Hadley Wood, in Thames Water’s Oakwood zone, about 267 mg/l.
Those are the two companies’ own published zone figures, not readings from your tap. On Affinity’s scale anything over 300 is very hard, which puts Mill Hill and Edgware in that class and the rest of the borough in the hard class, an 85 mg/l spread inside one borough. A combi in Mill Hill scales years before the same boiler in Hendon, and we fit a scale reducer on the main with every boiler in the borough for that reason.
Plumbing, heating, drainage, bathrooms and air conditioning from one firm, one number and one guarantee.
