It's probably an odd thing for an interior designer to say, but I don't think everyone needs an interior designer.

If you love spending your evenings researching furniture, have a clear idea of what you want, enjoy working through floor plans and can confidently make decisions about colour, scale, lighting and everything else that goes into a room, you may be absolutely fine doing it yourself.

And if you're painting a bedroom, replacing a chair or making a few small changes to a room you already love, paying a designer may not make much sense at all.

But there comes a point with bigger home projects when the question starts to change.

You're no longer wondering whether you could do it yourself. You're wondering whether you actually want to spend the next six months doing it yourself, and whether you're confident enough to make some fairly expensive decisions without knowing for certain how everything is going to come together.

That's usually when we hear from people.

They have good taste. They've saved plenty of inspiration. They know the sort of homes they love. What they don't necessarily have is the time, experience or headspace to turn all those ideas into one finished room.

So, is hiring an interior designer worth it?

"How do I make sure it won't date?"

It might be the question we're asked more than any other.

Whether someone's investing in a bespoke kitchen, renovating a period property or designing what they hope will be their forever home, there's almost always a quiet anxiety underneath the excitement. What if I spend all this money - all this time - and hate it in five years? What if I look back at the photographs and cringe?

It's a very human fear. And when you're making decisions that involve real money and real commitment, it deserves a real answer.

So let's get into it properly.

If you're highly capable in almost every other area of life but feel completely stuck when it comes to decisions around your own home, I promise you're not alone. It's rarely about taste. It's about carrying too many decisions at once, and I see it every single day, including in my own home.

I know, because I feel it too, and that might surprise you. Interior design isn't just my job, it's my passion. Yet when it comes to my own home, I struggle with exactly the same things you do.

Right now, I desperately need new bi-fold doors in my kitchen. Thirteen years ago, when we had an extension done, money was tight, so the doors to the garden had to be the cheapest I could find, or we lived with a gaping hole. They were cheap. A composite, laminated "wood" that did the job until water got into them and they slowly reverted to soggy sawdust. Not a great look, and definitely not secure.

That unloved room has been on your list long enough.

You've finally decided something has to change. The living room has felt 'almost right' for three years. The extension is going ahead and you're staring at an architect's plan with absolutely no idea what happens next. Or maybe you've just moved in and the whole house feels like a blank, slightly overwhelming canvas.

You know you want help. But what kind?

This is one of the questions we get asked most at The Living House - and it's a good one. Because choosing the wrong type of support at the wrong moment can leave you spending money you didn't need to, or - worse - not getting nearly enough help when you really needed it.
