If you’re pricing up a loft conversion for 2026, you’ll realise there’s no one-size-fits-all answer. Anyone who gives you one probably isn’t being totally honest. Costs vary, depending on the type of house and where you live.
How will the cost creep up?
Most homeowners in the UK are realistically looking at somewhere between £35,000 and £85,000 for a decent loft conversion. A straightforward job with roof windows, a basic layout, and no fancy extras, will sit towards the lower end. As soon as you start adding elements, like a staircase or an en-suite, the price naturally creeps up. The most common use is as an extra bedroom or increasingly, as people work more from home, a study.
Location makes a big difference too
Labour and materials cost more in some parts of the country. If you’re in or around London, prices tend to rise a lot. The same conversion that feels cheaper elsewhere can suddenly look eye-watering, once city costs are factored in.

Then there’s the detail
Storage, insulation and lighting are the bits that don’t always seem expensive. However, they add up faster than you expect. It’s also sensible to keep a bit of room in your budget.
A loft conversion in 2026 isn’t cheap
However, when you compare the cost to moving house, it often still stacks up. You’re paying for more space and things that can add long-term value to your family home.
