Date: 2 July 2025If you're thinking about buying a home – whether it's your first time or you're moving on – one of the best things you can do early on is get a mortgage decision in principle.
It’s a simple step that can give you peace of mind, speed things up later, and even put you ahead of other buyers.
Let’s take a look at what it actually is, why it matters, and how we can help you sort one out quickly and easily.
A mortgage decision in principle (often shortened to DIP) is a letter or certificate from a lender that shows how much they might be willing to lend you based on a few key details – like your income and any debts you have.
It’s not a full mortgage offer, and it’s not a promise – but it gives you a rough idea of your budget. Most estate agents and sellers will want to see one before they’ll take an offer seriously.
There are a few good reasons to get this sorted before you start viewing homes:
✅ You’ll know what you can afford – It gives you a clear idea of your price range, so you’re not wasting time on places that aren’t realistic.
✅ It shows you’re serious – Sellers and estate agents will often prioritise buyers who already have a DIP in place.
✅ You’ll be ready to move quickly – Once you find the right home, having a DIP can speed up the process.
✅ It can highlight any issues early – If there’s anything that might affect your borrowing, it’s better to know now – not when you’ve already found a place you love
Most of the time, no – it won’t. When you apply for a mortgage decision in principle, the lender will usually do what's called a soft credit check.
This means they’ll have a quick look at your credit file to get a rough idea of your situation – but it won’t leave a mark that other lenders can see, and it won’t affect your credit score.
A soft check is like a sneak peek. Only you can see it, and it doesn’t impact your credit in any way.
A hard check, on the other hand, is a deeper look at your credit history and does show up on your file. This only happens further down the line, when you’re ready to apply for a mortgage properly.
If you’re working on improving your score, it’s worth checking out Experian Boost. It’s a free tool that can give your score a bit of a lift by including regular payments like Netflix, council tax, or your phone bill in your credit record.
