Booking a national brand gets you a subcontractor. Booking us gets you an employed engineer in a Vantage van who was probably in the next street last week. We are in and out of Knebworth, Hitchin, Letchworth most weeks as well, so Stevenage is not a place we visit twice a year.
It matters most when something needs a second visit, because a firm that lives in the area turns up and a firm that does not sends a different person and starts again.
Affinity Water’s own published figure for the Stevenage supply zone, zone code AF008, is a mean total hardness of 320 mg/l as calcium carbonate.

Scale builds inside the boiler at the same rate whether the property is Old Town or one of the estates added since the 1990s, so the fix is the same regardless of postcode, a boiler sized and installed with proper scale protection from day one.
It is why we mention scale protection on new boiler installations and why we fit better brassware than the minimum on bathroom work.
Call and speak to a person, any hour, any day of the year.
