Derek is 27, rents a one-bedroom flat in Manchester for £850 a month, and has wanted to buy a home for three years. Every time he checks his savings, the number looks the same. The rent goes out, the bills go out, and whatever is left disappears into everyday spending. He just has never had a plan that treats the deposit as the first bill, not the last. Save for a House Deposit While Renting
This guide is the plan. It shows you how much deposit you actually need, what buying really costs on top of it, how the Lifetime ISA adds a 25 per cent government bonus, and how to find the money while you are still paying rent.
Quick Answer: Start with the target. A 5 per cent deposit on a typical first-time-buyer home costs around £11,280, and 10 per cent costs around £22,560 (Rightmove, October 2026). Open a Lifetime ISA if you are aged 18 to 39: save up to £4,000 a year and the government adds 25 per cent, up to £1,000 a year. Pay yourself first on payday and cut the rent or the bills that matter most. A realistic plan saves a 5 per cent deposit in two to three years and a 10 per cent deposit in four to five.
How Much Deposit Do You Actually Need?
The deposit is the first number to pin down, because everything else follows from it. Most lenders accept a 5 per cent deposit as the minimum, which means a 95 per cent mortgage. A 10 per cent deposit usually gets you a better interest rate and a wider choice of deals — but 5 per cent is a perfectly real starting point, and most first-time buyers start there.
How much that means in pounds depends on the price of the home. Rightmove puts the average asking price of a typical first-time-buyer home (up to two bedrooms) at £225,627 in October 2026. The Office for National Statistics average is higher, at £273,000 in August 2026, because that covers all homes, not just starter homes. Use the Rightmove figure for your target.
| Deposit size | On a £225,627 home (Rightmove, Oct 2026) | On a £273,000 home (ONS, Aug 2026) |
|---|---|---|
| 5% deposit | £11,281.35 | £13,650 |
| 10% deposit | £22,562.70 | £27,300 |
| 15% deposit | £33,844.05 | £40,950 |
Prices vary hugely by area: the ONS average is £294,000 in England, £216,000 in Wales, £198,000 in Scotland and £202,000 in Northern Ireland. Work out the price of the kind of home you want, in the area you want, and set your target from that — not from a national average. Our guide to how to find a rental property can help you research areas and prices while you are still renting.
The Buying Costs Nobody Warns You About
The deposit is not the only money you need. Budget roughly £1,600 to £3,500 on top of your deposit for the essentials, more if the home is leasehold or needs a full survey.
Conveyancing — the legal work — typically costs £1,200 to £2,500 all-in for a freehold purchase, including searches and registration. A Level 2 HomeBuyer survey costs roughly £400 to £1,000, and a Level 3 building survey for an older property runs from around £630 to £1,500 or more. Your lender may also charge a mortgage arrangement fee of £0 to £2,000. Removals, buildings insurance and the first month of bills add several hundred pounds.
Then there is stamp duty. In England and Northern Ireland, first-time buyers pay no stamp duty on the first £300,000 of a home costing up to £500,000, and 5 per cent on the part between £300,001 and £500,000. Above £500,000 the relief disappears entirely. Those thresholds have applied since 1 April 2025. On a £225,627 home, a first-time buyer pays £0.
| Buying cost | Typical range (2026) |
|---|---|
| Conveyancing (all-in, freehold) | £1,200–£2,500 |
| Level 2 HomeBuyer survey | £400–£1,000 |
| Level 3 building survey | £630–£1,500+ |
| Mortgage arrangement fee | £0–£2,000 |
| Stamp duty (first-time buyer, £225,627 home) | £0 |
Scotland and Wales differ. In Scotland, first-time buyer relief raises the Land and Buildings Transaction Tax nil-rate band to £175,000, saving up to £600. In Wales, there is no first-time buyer relief, but the Land Transaction Tax nil-rate band for a main home is £225,000. Always get an itemised quote from your solicitor, and check current rates on GOV.UK — older articles still quote the pre-April 2025 thresholds.
How Much Can You Borrow?
Your deposit is only half the equation. The other half is how much a lender will lend you, and that depends mostly on your income. Most UK lenders lend around 4 to 4.5 times your annual gross income, though some stretch to 5 or 5.5 times. A lender also runs a full affordability check, so the multiple is a guide, not a guarantee.
On a £35,000 salary, 4 to 4.5 times income means borrowing roughly £140,000 to £157,500. Add a £22,563 deposit (10 per cent of £225,627), and you can afford a home of around £162,500 to £180,000. On a joint income of £70,000, the same multiple means borrowing £280,000 to £315,000 — which is why buying with a partner changes the maths so dramatically.
Your credit history matters too: a thin or damaged file can mean a higher rate or a refusal. Paying rent on time does not automatically build your credit score — our guide on does paying rent build your credit score explains how. Check your report for free and fix any errors before you apply.
Mortgage rates also shape what you can afford: Rightmove reports the average two-year fixed rate at 5.49 per cent in autumn 2026, up from 4.53 per cent a year earlier. A bigger deposit lowers the amount you borrow and often the rate you pay.
The Lifetime ISA: The Government’s 25% Top-Up
If you are saving for a first home and you are under 40, the Lifetime ISA — usually called a LISA — is the single most valuable tool available to you. It adds 25 per cent to whatever you put in, up to £1,000 a year.
The rules, verified on GOV.UK and MoneyHelper, are:
| LISA rule | Detail |
|---|---|
| Age to open | 18 to 39 (first payment before your 40th birthday) |
| Annual limit | £4,000 per tax year (counts towards your £20,000 ISA allowance for 2026/27) |
| Government bonus | 25% of what you pay in, up to £1,000 per year, until you turn 50 |
| Property price cap | Home must cost £450,000 or less |
| Minimum wait | Buy at least 12 months after your first payment |
| Purchase conditions | First home only, bought with a mortgage, through a solicitor or conveyancer |
| Withdrawal charge | 25% on any other withdrawal before age 60 |
Save the full £4,000 in a tax year, and the government adds £1,000 — do that for five years and you have £25,000 before interest.
But the LISA has a trap. If you withdraw the money for anything other than a first home, reaching 60, or terminal illness, you pay a 25 per cent charge on the whole amount withdrawn — not just on the bonus. GOV.UK’s example: pay in £800, get a £200 bonus, withdraw the £1,000 pot, pay a £250 charge, get £750 back. You lose the bonus and £50 of your own money. Only put money into a LISA that you are confident you will use for a first home under £450,000.
The government is consulting on a replacement First Time Buyer ISA, announced in 2026. It is not available yet and there is no launch date — existing LISAs continue as normal, so do not close one.
Other Help Worth Knowing About
The LISA is not the only help available. A Help to Buy ISA closed to new accounts on 30 November 2019, but if you already have one, you can keep saving until 30 November 2029 and claim the bonus by 1 December 2030. The bonus is also 25 per cent, capped at £3,000, and the price cap is £250,000 outside London and £450,000 in London. If you have one, do not close it.
Gifted deposits are another route many first-time buyers rely on. Lenders accept them, but they will ask for a signed letter confirming it is a gift, not a loan, and that the giver has no claim on the property. Be honest about where the money comes from: hiding a loan as a gift is mortgage fraud.
The government has also announced Your First Home: a 2.5 per cent deposit plus a 20 per cent government equity loan on new-build homes. Full details are still to be confirmed, so do not build your plan around it yet. If owning outright feels out of reach, shared ownership and rent to buy let you start with a much smaller deposit.
Build Your Deposit-First Budget
Saving a deposit while paying rent is a maths problem before it is a willpower problem. Start with your take-home pay, subtract your fixed costs — rent, council tax, utilities, transport and food — and what is left is your real saving power. If that number is close to zero, you have a rent or income problem.
The rule that makes it work is simple: pay yourself first. Set up a standing order that moves your deposit amount into your LISA or savings account on payday, before you spend anything. A popular framework is 50/30/20 — 50 per cent on needs, 30 per cent on wants, 20 per cent on saving — but the split matters less than the habit. Start with whatever you can manage, even £50 a month.
List every subscription and direct debit and cancel anything you have not used in the last month. Audit your food spending for one month — meal planning and a weekly shop usually save £40 to £80 a month for a single person. Every pound you find goes into the deposit pot the same day.
Cut Your Rent and Bills Without Moving House
Rent is usually your highest cost, and it moves your timeline most. Cut it by £200 a month and that is £2,400 a year — nearly a quarter of a 5 per cent deposit on a £225,627 home.
The cheapest option is a house share. Moving from a one-bedroom flat to a room in a shared house can cut rent by £250 to £400 a month in many cities, and bills are usually split too. Soraya, for example, moved from a £950-a-month studio to a £600-a-month room in a four-bedroom shared house and put the £350 difference straight into her LISA.
If you like where you live, negotiate your rent when your fixed term ends — landlords often prefer a reliable tenant at a slightly lower rent to the cost of finding a new one. Bring evidence of similar homes at lower prices, and offer a longer fixed term in exchange. And check what you are actually paying for: our guide to what bills you pay when renting helps you spot charges that are not yours, and our energy bills guide shows how switching tariffs can shave £20 to £40 a month off your utilities.
| Rent-cutting move | Typical monthly saving |
|---|---|
| One-bed flat → room in a house share | £250–£400 |
| Negotiate rent at renewal | £30–£100 |
| Switch energy tariff and cut waste | £20–£40 |
| Cancel unused subscriptions | £20–£50 |
Boost Your Income While You Rent
Cutting costs has a floor; earning more does not. A second income stream of £200 a month adds £2,400 a year to your deposit — the same as a big rent cut, without moving anywhere.
Overtime and extra shifts are the simplest option if your employer offers them. Weekend or evening work in retail, hospitality or delivery is flexible and pays quickly. If you have a skill — design, writing, tutoring, coding, trades — freelance work can pay far more per hour. Selling things you no longer need can seed the first £500 in your LISA.
Be careful about tax: side income is taxable, and the trading allowance lets you earn up to £1,000 a year from self-employment without telling HMRC — above that, you must register and declare it. Check your tenancy agreement before running a business from home, and keep every pound of extra income separate from your spending money, moving it into the deposit pot the day it arrives.
Two Worked Examples
The numbers below are illustrative, using real 2026 figures and fictional personas.
Worked Example 1: Derek — The Five-Year LISA Plan
Derek, 27, saves the full £4,000 a year into a LISA — £333.33 a month. After five years his contributions total 5 × £4,000 = £20,000, and the government bonuses total 5 × £1,000 = £5,000. His LISA holds £25,000 before any interest.
A 10 per cent deposit on a £225,627 home is £22,562.70. Derek’s £25,000 covers it, leaving £25,000 − £22,562.70 = £2,437.30 towards his buying costs. His stamp duty is £0, because the home costs under £300,000 and he is a first-time buyer.
At the low end, conveyancing plus a Level 2 survey costs £1,200 + £400 = £1,600, leaving him £837.30 spare. At the high end, £2,500 + £1,000 = £3,500, and he would be £1,062.70 short — so he keeps saving a few more months or shops around for cheaper quotes.
Worked Example 2: Callie — Cutting Rent to Speed Up
Callie, 29, rents a one-bedroom flat for £1,100 a month and has no savings. She moves to a room in a house share at £750 a month, saving £350 a month, and cuts bills and subscriptions by £80 a month. That is £430 a month in total, or £5,160 a year.
Over three years she saves £5,160 × 3 = £15,480 of her own money. She puts £4,000 a year into a LISA, earning a £1,000 bonus each year — £3,000 in total. After three years, she has £15,480 + £3,000 = £18,480.
A 5 per cent deposit on £225,627 is £11,281.35, which she covers with £7,198.65 to spare. A 10 per cent deposit is £22,562.70, leaving a shortfall of £4,082.30 — about 10 more months at £430 a month (£4,082.30 ÷ £430 = 9.49). Cheaper rent turns a hopeless goal into a three-to-four-year plan.
What NOT to Do With Your Deposit Fund
A few shortcuts look tempting and will cost you. Do not borrow the deposit on a credit card or personal loan: lenders will spot it and it damages your affordability check, and a loan dressed up as a gift is mortgage fraud. Do not empty your pension: the tax penalty is severe, and you are trading your retirement for a smaller mortgage.
Do not put your deposit fund into stocks and shares or crypto if you plan to buy within five years — the value can fall just when you need it. A cash LISA or a high-interest savings account is the right home for money you need soon. And do not keep the fund in your everyday current account, where it gets spent by accident. Separate it, automate it, and do not touch it until exchange day.
Frequently Asked Questions
How much deposit do I need as a first-time buyer in the UK?
Most lenders accept 5 per cent, which is £11,281.35 on a typical first-time-buyer home at £225,627. A 10 per cent deposit of £22,562.70 usually gets you better rates and more choice.
Can I use a Lifetime ISA to save for a house deposit?
Yes, if you are aged 18 to 39. Save up to £4,000 a year, and the government adds 25 per cent, up to £1,000 a year. The home must cost £450,000 or less, and you must wait at least 12 months after your first payment.
How long does it take to save for a house deposit while renting?
Saving £430 a month reaches a 5 per cent deposit of about £11,280 in roughly 26 months. A 10 per cent deposit of about £22,560 takes roughly four and a half years at the same rate, or about three and a half years with a LISA bonus.
Do first-time buyers pay stamp duty?
In England and Northern Ireland, first-time buyers pay no stamp duty on the first £300,000 of a home costing up to £500,000. On a £225,627 home, you pay £0.
Is it better to save for a bigger deposit or buy sooner with 5 per cent?
A bigger deposit usually means a lower rate and lower monthly payments, but waiting years to save 15 per cent can cost more if prices rise. For most renters, 10 per cent is the sweet spot.
Can my parents gift me a deposit?
Yes. Lenders accept gifted deposits, but they need a signed letter confirming it is a gift, not a loan, and that the giver has no claim on the property.
What happens if I withdraw from a Lifetime ISA to buy a car?
You pay a 25 per cent charge on the whole amount withdrawn. On a £1,000 withdrawal, that is £250 — you lose the bonus and £50 of your own money. Only save in a LISA what you will use for a first home.
Can I save for a deposit on a low income?
Yes, but the plan changes: a house share or cheaper area cuts your rent, a LISA still adds 25 per cent to small amounts, and shared ownership or rent to buy can halve the deposit you need.
Should I put my deposit savings in stocks and shares?
Not if you plan to buy within five years. The value can fall when you need it most. A cash LISA or high-interest savings account is safer for money you need soon.
Can I get a mortgage with a 5 per cent deposit?
Yes, most lenders offer 95 per cent mortgages to first-time buyers with a good credit history and affordable income — at a higher interest rate than with a 10 per cent deposit.
Final Thoughts
Saving for a deposit while renting is slow, and slow is fine. The renters who buy are not the ones who saved fastest — they are the ones who set a target, opened a LISA, automated the saving, and kept going when it felt pointless. Derek’s and Callie’s plans both start the same way: one standing order, set up today.
Work out your target from the price of the home you want. Open a LISA if you are eligible. Cut the rent or the bills that move the needle most. And if you are still weighing renting against buying, our rent affordability calculator shows you what your current rent means for your monthly budget.
