GOOD TO KNOW
An unexplained rise in your water bill, or a water meter that keeps ticking over when nothing's running in the property, is one of the clearest early signs of a hidden leak. Most water companies can help identify whether the leak is on your side of the meter (your responsibility) or theirs.
TIME OF YEAR TIPS
Pipes in unheated spaces — lofts, garages, outbuildings — are the most common source of a winter burst pipe once temperatures drop below freezing for a sustained period. Lagging exposed pipework and keeping heating on a low constant setting during a cold snap, rather than off, are the two most effective preventive steps.
COST & QUOTES
Three is a reasonable number for most plumbing jobs — enough to spot an outlier without asking too many people to visit for a straightforward repair. For a planned job like a bathroom refit, make sure each quote covers the same scope, since a lower price sometimes means less is included, not better value.
SEASONAL ADVICE
Before winter: check outside tap isolation valves, and consider draining down any external pipework not in regular use. Before summer: check garden irrigation and outside tap connections for wear, since these see much more use once the weather turns. A five-minute check avoids most seasonal callouts.
THE PROCESS EXPLAINED
Modern combi boilers display a fault code when something's wrong rather than just stopping — the exact meaning varies by manufacturer, but common causes behind a "no heat" code include low pressure, a faulty sensor, or an ignition fault. Note the code before calling a plumber; it speeds up diagnosis considerably.
SEASONAL ADVICE
An outside tap needs its own isolation valve and, in colder areas, either an internal shut-off you can drain down for winter or a proper anti-frost design — a poorly installed one is a common cause of a burst pipe in cold weather. This is separate from the electrical requirements for any pond or irrigation pump also being installed.
HOW IT WORKS
Unlike electric underfloor heating, a water-based system runs off your boiler via a manifold and needs the floor buildup to accommodate the pipework — usually easier to fit during a renovation than retrofit into a finished floor. It's often paired with a lower-temperature heating setup than radiators use.
UNDERSTANDING THE JOB
Most combi boilers run best between 1 and 1.5 bar of pressure — too low and the heating cuts out, too high and the pressure relief valve can discharge. A plumber checking a heating fault will usually look at pressure, check for trapped air in radiators (bleeding), and check the pump and diverter valve before assuming a full boiler fault.
LOCAL AREA
Harlow was one of the earliest wave of post-war new towns, designated in 1947, and its planners were unusually ambitious about public art and modern civic design for a town of its size. The neighbourhoods were laid out with housing kept apart from through-traffic on purpose, which still makes for straightforward, predictable access today. That first generation of 1950s and 60s housing is old enough now that a meaningful share has already been through a full round of rewiring, re-roofing or re-rendering. Newer infill built more recently sits alongside that older new-town stock rather than replacing it outright, so it's worth checking a specific street's actual age rather than assuming.
In Harlow the blend of 1950s–60s housing and newer infill means plumbers frequently handle everything from basic leak repairs to full replumbing during extensions. Older systems may show corroded copper pipework or obsolete fittings that become apparent during showers of remodeling, and newer builds commonly need first‑fix plumbing for loft conversions or extensions. WRAS‑approved fittings must be used for mains water work to protect the supply, and unvented cylinder installations require a G3‑qualified engineer to ensure safety compliance.
Powerflushing can be necessary where older radiators are cold at the bottom, but plumbers coordinating with heating engineers should plan this work. When requesting quotes in Harlow, ask plumbers for WRAS compliance documentation and G3 certification where relevant, and request a pre‑work inspection that looks for hidden corrosion or failing joints. Also confirm how they’ll stage deliveries and protect existing finishes in mid‑century interiors.
