How much house can I really afford in the UK?

Why this question matters

Affordability is often treated as one headline number. In reality, most people feel affordability month by month. That means the mortgage is only part of the picture. Commuting costs, council tax, childcare, utilities and the basic cost of running a home can all shift the answer.

This is why two properties with similar prices can create very different lifestyles. One may leave you with room to save, enjoy weekends and handle surprises. The other may technically be possible, but still feel tight every month.

What traditional affordability calculators miss

• Commuting costs: train tickets, fuel, parking and Tube travel can easily add hundreds each month.
• Council tax: this varies by property and location and is often underestimated.
• Utilities and running costs: older or larger homes can be more expensive than expected.
• Lifestyle costs: food, childcare, subscriptions and everyday spending do not disappear after a move.
• Comfort: a budget that works on paper can still feel stressful in real life.

A simple example

What to look at instead

A more realistic affordability check should ask: how much will be left after your core housing and lifestyle costs are covered? That leftover amount is often a better reflection of whether somewhere feels sustainable.

You do not need a perfect model. You just need something that reflects real life more honestly than borrowing power alone.
