Plumbing and heating in Hertfordshire
Hertfordshire has some of the hardest water in the country. Limescale builds up in boilers, cylinders, immersion heaters, taps and shower heads, cutting efficiency and shortening their lives.
We repair and replace scaled-up parts, power flush heating systems, and advise on protecting a new boiler or cylinder from limescale.
What we see most in Hertfordshire
Very hard water
Limescale is behind many immersion heater, boiler and hot water faults in the county.
Larger homes
Bigger heating systems and cylinders that need balancing and regular attention.
Hot water cylinders
Many Hertfordshire homes run a cylinder with an immersion heater. We repair and replace both.
Neighbourhoods we cover in and around Hertfordshire: Potters Bar, Cheshunt, Hatfield, Watford, Hertford.

Reviews from our customers
Very fast and reliable and honest.
Eljo from Urgent Plumbers London Ltd is one of, if not the most responsive tradesman I've come across - replied to queries and messages quickly without fuss, and clearly explained issues/reasoning with any work required. Always arrived when he said he would too and was happy to provide all relevant documentation (Gas Safe etc) when asked - would recommend. Quoted for boiler service/replaced our boiler when it was found to be un-serviceable.
Urgent Plumbers were fantastic when my boiler leaked. It was at the worst time possible -early on a Sunday morning when I was rushing out to work. He was so calm , turned up quickly as promised and then was so efficient at working out and fixing the problem. He was also so kind as I was terrified how much it would all cost for a Sunday emergency call out Thank you so much - you're an absolute hero
