Which towns do we cover in County Londonderry?
Most of County Londonderry is supplied with soft water. That leaves you free to choose matt black, brushed brass or clear glass without worrying much about limescale. Hardness varies street by street, so check the figure for your postcode with your water supplier. For listed and period properties in Derry, we check early whether listed building consent applies to the work you have in mind.
What the job includes
- Strip-out back to brick or studwork, with waste taken away by a licensed waste carrier
- New hot and cold pipework and wastes, with isolation valves to each fitting
- Repairs to rotten floorboards, joists or other timber found once the room is open
- A survey of the structure and services: joists, walls, ceilings, pipework, wastes, wiring and ventilation
- Re-plastering or boarding, with cement-based boards and tanking in the wet areas
- Layout changes such as moved doors, new stud walls or boxing for concealed cisterns
Decisions to make first
Pipe material
Copper suits exposed runs and the area near the boiler. Plastic pipe is quicker under floors and inside walls, and long runs need fewer joints.
Shower floor
With the floor already up, a renovation is the easiest time to form a level shower floor or a full wet room.
How far back to strip
Back to brick gives a clean start. Keeping sound plaster on some walls saves time and money, and the survey shows which walls can stay.
Plaster or boards
Plaster suits dry walls that will be painted. Cement-based tile backer boards are the better base behind showers and under heavy tiles.
Rules that apply in Northern Ireland
Renovating a bathroom inside an existing home does not need planning permission. Listed buildings need listed building consent for alterations that affect their character, which can include internal work and new soil or vent pipes through walls. In a flat, check the lease: freeholder consent is often needed for wet rooms, moving the WC or new extract vents, and sound insulation and leak risk to the flat below matter. Electrical work must meet BS 7671, with 30 mA RCD protection on every bathroom circuit.
In Northern Ireland, building control covers drainage, structural changes and ventilation, with ventilation set out in Technical Booklet K. There is no Part P, but new wiring should be designed, tested and certified to BS 7671.
