How much would a basic loft conversion cost?
Thinking about a loft conversion? It's one of those things that sounds great in theory—more space, higher property value, all that. But then you hit the big question: how much is this actually going to set me back? For a straightforward, no-frills conversion in the UK, you're looking at somewhere between £20,000 and £40,000. That usually gets you a basic room with a dormer window, insulation sorted, flooring, plastering, and a proper staircase. But honestly? The final number depends on your house, where you live, and how fancy you want to get with the finishes.
What is included in a basic loft conversion price?
So what do you actually get for that money? It's basically turning your dusty attic into a usable room—like a bedroom or home office. The package covers the structural stuff, basic finishes, and making sure everything meets building regs. Here's the usual breakdown:
- Structural work: Steel beams, new floor joists, and maybe a dormer window if needed.
- Basic insulation: The kind that ticks the boxes for thermal and sound—nothing fancy.
- Plastering and decoration: Plasterboard goes up, walls and ceiling get a basic paint job.
- Staircase installation: A fixed staircase from the floor below—because climbing a ladder gets old fast.
- Electrical work: A few sockets, some light points, and a smoke alarm to keep things safe.
- Window installation: A standard double-glazed window, usually a roof window or dormer.
How much does a loft conversion cost per square metre?
If you want to compare quotes like a pro, look at the cost per square metre. For a basic conversion, it's roughly £1,000 to £1,500 per square metre. That covers labour, materials, and standard finishes. So if your loft is 30 square metres, you're looking at £30,000 to £45,000. Simple math, painful numbers.
Factors that affect the cost per square metre:
- Property type: Terraced houses tend to be cheaper—simpler roof structures mean less hassle.
- Roof complexity: A straightforward gable end roof? Easy. A hipped roof or one with weird angles? That's gonna cost more.
- Location: London and the South East? Expect to pay 20-30% more than up North. Just the way it is.
What are the different types of basic loft conversions and their costs?
The type of conversion you go for changes the price a lot. Here's a quick comparison of the common ones:
| Type of Conversion | Typical Cost Range (UK) | Best For |
|---|---|---|
| Roof Light (Velux) | £20,000 – £30,000 | Simple rooms where you already have headroom—no major structural changes. |
| Dormer (rear) | £25,000 – £40,000 | Adding real floor space and proper headroom. |
| Hip-to-Gable | £30,000 – £45,000 | End-of-terrace or semi-detached houses with hipped roofs. |
People Also Ask:
Is a loft conversion worth the money?
Honestly? Yeah, usually. A basic loft conversion can bump your property value by 10-20%—that's often £30,000 to £50,000, which is more than what you'd spend. Plus, you skip the whole nightmare of moving house. So it's not just about the space, it's about the investment.
Do I need planning permission for a basic loft conversion?
Most basic conversions fall under Permitted Development, so you don't need full planning permission. But—and it's a big but—you have to stick to rules about volume, height, and distance from boundaries. If you're in a conservation area or a listed building, forget it, you'll need permission. And no matter what, Building Regulations approval is mandatory.
How long does a basic loft conversion take?
Figure on 4 to 8 weeks from start to finish. That includes design, structural work, insulation, plastering, and final touches. But delays happen—bad weather, material shortages, or finding something nasty in the roof. So don't plan a house party for week 5.
Expert Tips for Keeping Costs Down
- Get multiple quotes: At least three. Compare prices and scope—don't just go with the first builder who smiles at you.
- Choose a simple design: A straightforward dormer or roof light conversion is way cheaper than a fancy mansard.
- Do some DIY work: Painting, decorating, or even plasterboarding if you're handy. Just don't mess up the structural stuff.
- Plan for hidden costs: Budget an extra 10-15% for surprises like asbestos or reinforcements. Trust me, they happen.
Frequently Asked Questions (FAQ)
Does a basic loft conversion include a bathroom?
Nope. A basic conversion doesn't cover a bathroom. Adding one means extra plumbing, drainage, and tiling—that's another £5,000 to £10,000. If you want an en-suite, you're looking at a more comprehensive (and expensive) job.
Can I finance a loft conversion?
Yeah, lots of people use home improvement loans, remortgage, or even credit cards. Some builders offer payment plans too. Just check the interest rates and terms before you sign anything.
Will my loft conversion require building regulations?
Absolutely. No way around it. Building Regulations cover structural safety, fire safety, insulation, and soundproofing. You'll need to submit plans and have the work inspected. Don't skip this—it's not optional.
