Working in Allerton
We cover every part of Allerton, including L18, L19 and L25, and nearby Hunts Cross (1.4 miles) and Garston (2.3 miles).
Being a smaller town does not change how we work in Allerton: free survey, written quote, one team. We plan loft bathrooms in Allerton around the roof line, so the shower sits where you can stand and the eaves become storage. If your Allerton home has a gravity-drained WC on another floor, a macerator in the loft may open up more layout options.
Supplies across most of Merseyside are soft. If that holds for your street in Allerton, limescale on shower glass and heads builds up slowly and a squeegee after use is usually enough. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- A shower pump on a gravity system, an electric shower, or advice on moving to mains pressure, depending on your system
- Electrics by a qualified electrician, tested and certified, then tiling, testing and handover
- Fitted furniture made to the eaves, so the low space behind the slope becomes storage
- A drainage route from the loft to the soil stack with enough fall, or a pumped waste or macerator where the rules allow it
Decisions to make first
Bath or no bath
A bath under the slope makes good use of low space, but the floor has to carry it when it is full of water and someone is in it.
Roof window
A roof window over the bath or shower brings daylight and fresh air, but plan the blind for privacy and expect condensation on cold glass.
Rules that apply in England
In England, new drainage and a new connection to the soil stack fall under Part H, a new bathroom needs extract of 15 litres per second intermittent or 8 litres per second continuous under Approved Document F, and new circuits are notifiable under Part P. If the work includes an unvented hot-water cylinder, it must be fitted by a G3-qualified installer.
