In a city the size of Milton Keynes, parking and access for a skip are worth sorting before the start date — we will ask at the survey. For a loft bathroom in a tank-fed Milton Keynes home, we work out how the shower will get its pressure before choosing a single fitting. If your Milton Keynes loft conversion has a bedroom but no bathroom, the survey starts with where the soil stack runs and how much headroom you have.
Most of Buckinghamshire has hard water. If your supply in Milton Keynes is the same, limescale on shower glass and heads is a real issue: easy-clean glass, rub-clean nozzles and a squeegee make a big difference. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- Electrics by a qualified electrician, tested and certified, then tiling, testing and handover
- A drainage route from the loft to the soil stack with enough fall, or a pumped waste or macerator where the rules allow it
- An extractor fan ducted through the roof or a gable wall, with the duct insulated through cold spaces
- Fitted furniture made to the eaves, so the low space behind the slope becomes storage
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.
Getting the water pressure
A pumped shower suits a gravity system with a cold tank; an electric shower heats cold mains water at the point of use; a combi or unvented cylinder gives mains pressure throughout.
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.
