How to Save for a Mortgage Deposit in the UK: A Practical Guide from Real Client Experience

Saving for a mortgage deposit is one of the biggest challenges facing home buyers in the UK today. In my experience working with clients over many years at WIS Mortgages, this is often the main obstacle, even for people with excellent credit scores and strong incomes.

This guide is not built on theory. It is based on what has actually worked for our clients. These are the habits and strategies that consistently help people move from “we cannot save anything” to “we are ready to buy”.

Why Saving a Deposit Feels So Difficult

Most people do not fail to save because they do not earn enough. They fail because small spending habits slowly drain money without being noticed. Once this leakage is fixed, the deposit starts growing far faster than most people expect.

Practical Deposit Saving Strategies That Work

Review Your Bank Statements and Credit Cards

This is always our first step with clients.

We regularly find duplicated subscriptions such as Amazon Prime, Netflix, Disney+, Spotify and other services. Removing just a few unused subscriptions can free up £30 to £60 per month, which becomes £360 to £720 per year towards your deposit.

Reduce Entertainment Spending Without Losing Your Lifestyle

Regular spending on pubs, restaurants and takeaways adds up quickly.

You do not need to remove all enjoyment from your life, but choosing lower-cost options more often can release hundreds of pounds every month. The savings go directly into your deposit.

Avoid Buy Now Pay Later Schemes

Schemes like Klarna feel painless but directly slow your deposit progress.

A £100 purchase still costs £100, even when spread across months. Multiple small purchases quietly eat into what could have been your deposit fund.

Shop for Groceries Online

Online grocery shopping reduces impulse buying and keeps spending controlled. While delivery may cost a few pounds, many clients save £15 to £20 per shop by avoiding unnecessary items.

Limit Spending on Expensive Brands

There is rarely a meaningful difference between a £20 T-shirt and a £100 T-shirt. Reducing brand spending, even slightly, makes a noticeable difference over a year.

Review Your Utility Providers Regularly

Most households are not on the cheapest tariffs for gas, electricity or broadband. Saving just £100 per month across utilities creates £1,200 per year towards your deposit.

Reduce Credit Card Interest

High-interest credit cards destroy savings.

If possible, move balances to a 0 percent balance transfer card or switch to a lower-interest option. A £10,000 balance at 25 percent interest costs around £2,500 per year in interest alone.

Choose Phones and Cars Carefully

Avoid expensive phone contracts when older models offer similar performance. Saving £20 per month on your phone equals £240 per year.

With cars, finance costs are often the biggest obstacle. Switching from a £500 per month car payment to £250 frees up £3,000 per year for your deposit.

Consider Lower Rent Where Practical

Some clients move slightly outside town, especially when working from home. Saving £200 per month on rent creates £2,400 per year for your deposit.

Save Bonuses and Pay Rises in Full

You are already used to living without them.

Saving all bonuses and pay rises accelerates deposit growth with very little lifestyle impact.

Use High Interest Savings and Government Schemes

Store your deposit in high-interest savings accounts.

If eligible, use a Lifetime ISA, which provides a 25 percent government bonus on your savings. Consider investing only with proper professional advice.

Key Findings from Client Experience

• Deposit success depends more on behaviour than income
• Small consistent changes create large long-term results
• Discipline is the single most important factor
• Even high earners struggle without structure

Final Thoughts

Saving for a mortgage deposit requires commitment and consistency.

When these habits are applied properly, almost every client succeeds, even when their starting position feels impossible.

Frequently Asked Questions

How much deposit do I need in the UK?

Most buyers aim for 5 to 10 percent of the purchase price, though higher deposits often unlock better mortgage rates.

Can I save a deposit on an average income?

Yes. We see this achieved regularly with the right financial structure and discipline.

Should I invest my deposit savings?

Possibly, but only with professional financial advice and a clear understanding of risk.

Are Lifetime ISAs still available?

Yes, though eligibility is limited and the scheme will eventually close. If you qualify, they are one of the most powerful deposit-building tools available.

If you would like personalised guidance on creating your own deposit plan, the team at WIS Mortgages would be happy to help.

Saving for a home is not easy, but with the right structure, it is absolutely achievable.

Important FCA Warning

As a mortgage is secured against your home, it may be repossessed if you do not keep up the mortgage repayments.
