Kitchen plumbing in Orpington

Thinking about kitchen plumbing in Orpington?

Plenty of Orpington kitchens still have the sink where it was put decades ago, and moving it under the window or into an island is a common reason to call a plumber.

If your Orpington home has a solid concrete ground floor, a new sink or appliance position may mean cutting a channel for the waste, which is worth planning before the units arrive. If your home is in Orpington or close by in Chislehurst or Swanley, the same survey, quote and fitting process applies.

House types around Orpington and what they mean for a kitchen

The housing mix across Greater London includes Victorian and Edwardian terraces, conversion flats, mansion block flats and 1930s semis, so no two kitchen fits are quite alike. Victorian terraces often have a narrow galley beside the side return, while conversion flats and mansion blocks usually fit the kitchen into a small room or along one living-room wall.

Permit parking, red routes and flats without lifts are common, so parking suspensions, stair carries and lift bookings may need arranging before delivery day. London's mains water is hard, so limescale builds quickly on taps and boiling water taps, and a scale-reducing filter is worth planning in.

Building regulations, electrics and gas in Orpington

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.

Conservation areas are widespread across London, so a new extractor vent on a front wall may need permission, and leaseholders usually need the freeholder's written consent first.

Worth knowing before the fit

In a flat in Orpington, check your lease before moving the sink, as moving services usually needs the freeholder's written consent.
Plan a day or two without a working sink in your Orpington kitchen, and fill a few large bottles before the water goes off.
If your house in Greater London has a solid floor, ask at the survey where a waste could run before you settle on an island sink.
Keep the sink near an outside wall or the existing stack where you can, because long waste runs need a fall the units must hide.

Questions about kitchen plumbing in Orpington

How much does kitchen plumbing cost in Orpington?

Guide prices in Orpington are about £260 to £650 including VAT for connecting the sink, dishwasher and washing machine. The final price depends on the size of the kitchen and what is moving, and is set out in an itemised written quote.

Do you cover all of Orpington?

Yes. We work across Orpington, including the BR6 postcode district, and nearby towns such as Chislehurst and Swanley. Book a free survey visit and we will arrange a time that suits you.

Can a kitchen sink be moved to a different wall?

Yes, usually. The supplies are the easy part; the waste decides it, because it needs a steady fall all the way to the stack or drain. On a suspended timber floor the pipe can often run between the joists, while on solid concrete a channel may need to be cut and filled. Where a fall cannot be achieved, a pumped waste is sometimes considered.

What happens to the old pipes during a kitchen refit?

Pipes that will no longer serve anything are cut back to the nearest live pipe and capped, rather than left as long dead ends behind the new units. Water sitting in an unused length of pipe can go stale, and a forgotten joint can leak where nobody will see it. Old wastes are removed or sealed so they cannot let drain smells back into the room.

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.
