House types around Potters Bar and what they mean for a kitchen

In and around Potters Bar, homes range across 1930s semis, post-war new town houses, Victorian terraces and new-build estates. Stevenage and Hemel Hempstead new-town houses often have a small galley, while 1930s semis tend to have a narrow kitchen beside the dining room.

Hertfordshire's water is very hard, mostly drawn from chalk, so limescale on taps and boiling water taps is common and a softener or filter is worth considering. Commuter-town streets often have tight parking, and estate houses with shared parking courts can mean carrying units some distance to the front door.

What rules apply to kitchen plumbing in Potters Bar?

In England, kitchen pipework and fittings must meet the Water Supply (Water Fittings) Regulations 1999, which cover suitable materials, backflow protection and preventing waste or contamination of the supply. Connecting a sink to an existing waste or stack is routine, but a new connection to an underground drain, or a change to how waste water is discharged, involves building control. Gas pipework to a hob or cooker is separate work for a Gas Safe registered engineer.

A kitchen fit needs no planning permission, but listed buildings and conservation areas, including parts of St Albans and Welwyn Garden City, may need consent for external vents.

Worth knowing before the fit

Measure the cupboard under your sink before buying a boiling water tap for your Potters Bar kitchen, as the tank and pipework need clear space.
Ask for an access point on the waste near the sink, so a future blockage can be cleared without taking a unit out.
Plan a day or two without a working sink in your Potters Bar kitchen, and fill a few large bottles before the water goes off.
Ask for redundant pipes to be removed back to the live supply rather than left behind units, where they can hold stale water or leak.

Which parts of Potters Bar do you work in?

All of them. Our Hertfordshire coverage takes in the whole of Potters Bar, including the EN6 postcode district, as well as surrounding towns such as Barnet. If you are unsure, send us your postcode.

Why should every appliance have an isolation valve?

An isolation valve lets you shut off the water to one tap or appliance without turning off the whole house. If a dishwasher hose splits or a tap needs a new cartridge, you turn a small screw or lever under the sink and the rest of the home keeps running. Valves are fitted on the hot and cold tap feeds and on each appliance supply.

What plumbing does a boiling water tap need?

A boiling water tap needs a cold supply to a tank under the sink, usually through a filter, plus an electrical socket or spur for the tank. Some models also take hot and cold feeds for the mixer side. The tank uses cupboard space, so the sink unit is planned around it, and the tap's minimum water pressure is checked against your supply.

When does kitchen plumbing need building control?

Most kitchen plumbing does not. Replacing a sink, adding appliance connections and rerouting supply pipes inside the kitchen are routine. A new connection to an underground drain, or a change in how waste water is discharged, needs building control approval in England, Wales and Northern Ireland, or a building warrant in Scotland. Every fitting must also meet the water fittings rules for your nation.
