Loft conversions in Sandwell

What should you know before starting in Sandwell?

In Sandwell, Sandwell Council decides planning questions. We check permitted development limits and any local restrictions at the survey, then deal with the Building Regulations side so you receive a completion certificate when the work is signed off.

Every habitable loft room needs Building Regulations approval, including fire protection to the stairway below.
A dormer on the roof slope facing the street, or one that rises above the ridge, needs a planning application.
The new staircase usually needs 2 metres of headroom, with a little leeway allowed for loft conversions.

Which option fits your home?

Roof-light conversion

The simplest option: the roof shape stays the same and roof windows are fitted into the slope. It works when there's already enough head height, keeps costs down, and is often permitted development because roof lights can project up to 150 mm from the roof plane. You do lose some usable floor area under the sloping ceilings.

Shower room in the loft

Most conversions include a shower room or en-suite. Placing it close to the existing soil stack keeps the waste run short and reliable. Because of the sloping ceilings, the shower goes where the head height is, often within the dormer, while the WC and basin can sit under the lower parts of the roof.

Your questions answered

Will I lose space on the landing?

Usually very little, because the new staircase normally sits above the existing one. Sometimes part of a box room or a cupboard is used to fit the stair in, especially where head height is tight. We show you exactly where the stair lands on the drawings before you agree to anything, because its position decides how both floors work.

How do I book a survey in Sandwell?

Send the form on this page, use the guide-price tool or call 0800 088 6248 free. We'll ask a few questions about your loft conversion and arrange a time to visit.

How long does a loft conversion take?

Most take 6–10 weeks on site, with roof-light conversions at the shorter end and hip-to-gable or mansard work at the longer end. Allow time beforehand for drawings, a lawful development certificate or planning decision, and party wall notices, which need two months on a semi or terrace. We plan the start date around those periods so nothing is left waiting.

Will I need permission from the council in Sandwell?

Usually building control, and sometimes planning. Sandwell Council is the planning authority for Sandwell; Building Regulations approval comes from its building control team or a registered building control approver. We'll tell you which applies after the survey.
