Saving for a House Deposit in 2026: How Long Will It Actually Take?
How long to save a UK house deposit in 2026: LISA bonus, Help to Save, average deposit amounts by region, salary sacrifice, investment vs cash ISA — with real worked examples.
Part 6: Saving for a House Deposit — How Long Will It Actually Take?
This is Part 6 of 12 in our "Buying Your First Home — month by month" series. ← Part 5: Stamp Duty and Buying Costs | Part 7 →
Saving a house deposit is one of the longest phases in the entire homebuying journey — and one of the least well-understood. First-time buyers routinely underestimate how much they actually need (it is not just the deposit percentage; it is the deposit plus stamp duty plus solicitors plus survey), and overestimate their savings speed without accounting for the months when life intervenes.
This guide gives you honest, region-specific timelines based on real UK salary and savings data. It covers every tool available to you — LISA, Cash ISA, Help to Save, salary sacrifice — and explains what each does and does not do.

The deposit percentage you should target depends on three things: where you are buying, what mortgage rate you want to access, and whether you are comfortable at 95% LTV.
The rate impact of LTV tiers in 2026:
| LTV | Typical 5-year fix | Monthly payment (£200k, 25yr) | Extra cost vs 85% LTV |
|---|---|---|---|
| 95% | 5.2–5.8% | £1,295–£1,370 | £120–£195/month |
| 90% | 4.6–5.0% | £1,205–£1,260 | £30–£85/month |
| 85% | 4.3–4.7% | £1,175–£1,220 | — |
| 80% | 4.1–4.5% | £1,148–£1,197 | Savings vs 85% |
The difference between 95% and 85% LTV is roughly £120–£195 per month on a £200,000 mortgage — that is £7,200–£11,700 over a five-year fix. Saving an additional 5–10% deposit is almost always worthwhile if the timeline extends by less than 12 months.
Deposit targets by region:
| Region | Avg FTB price (2026) | 5% deposit | 10% deposit | 15% deposit |
|---|---|---|---|---|
| London | £520,000 | £26,000 | £52,000 | £78,000 |
| South East | £330,000 | £16,500 | £33,000 | £49,500 |
| South West | £280,000 | £14,000 | £28,000 | £42,000 |
| East of England | £295,000 | £14,750 | £29,500 | £44,250 |
| West Midlands | £225,000 | £11,250 | £22,500 | £33,750 |
| Yorkshire | £200,000 | £10,000 | £20,000 | £30,000 |

| North East | £155,000 | £7,750 | £15,500 | £23,250 |
| Scotland | £195,000 | £9,750 | £19,500 | £29,250 |

Important: the deposit is not the only cash you need at purchase. In Part 5 of this series, we covered the full cost breakdown — solicitor fees (£1,500–£3,000), survey (£500–£1,500), and stamp duty (£0–£11,250 for most first-time buyers in England). Budget the deposit plus £3,000–£5,000 for these additional costs. Do not arrive at completion with your deposit account exactly at the target.
The Savings Tools Available to UK First-Time Buyers in 2026
1. The Lifetime ISA (LISA)
The LISA is the most powerful savings tool available to first-time buyers under 40. There is nothing else in the UK market that offers a guaranteed 25% return on contributions.
How it works:
- Open between ages 18 and 39 (contributions allowed until age 50)
- Save up to £4,000 per tax year (6 April to 5 April)
- HMRC adds a 25% bonus — £4,000 becomes £5,000
- Interest or investment growth applies to the full £5,000
- The bonus is paid monthly by most providers (Moneybox, Nutmeg, AJ Bell)
Rules for using a LISA on a home purchase:
- Property must cost £450,000 or less
- You must be a first-time buyer (never owned property in the UK or abroad)
- The account must have been open for at least 12 months before use
- Funds go directly to your conveyancer — not to you
The withdrawal penalty: if you take money out for any reason other than a first home (at age 60+, or terminal illness), HMRC charges a 25% withdrawal penalty on the total amount withdrawn. On £5,000 (your £4,000 plus the £1,000 bonus), the penalty is £1,250 — leaving you with £3,750, which is less than your original £4,000 contribution. The LISA is strictly for first home or retirement.
Cash LISA vs Stocks and Shares LISA:
For deposit timelines under 4 years, a Cash LISA is the safer choice. Cash LISAs from leading providers are currently paying 4.0–4.75% AER (2026 rates from Moneybox, Paragon, Beehive Money). If you are 5+ years from buying, an S&S LISA offers higher expected returns but with market risk.
Maximise the LISA from day one. Open it before you do anything else — the 12-month clock starts from account opening, not from your first contribution.
2. Cash ISA
After maxing the LISA, a Cash ISA is the best home for your remaining deposit savings. The annual ISA allowance is £20,000 total (2025/26 and 2026/27). With £4,000 in a LISA, you have £16,000 of remaining ISA allowance for a Cash ISA.
2026 Cash ISA rates (approximate):
- Easy-access: 4.0–4.5% AER (Coventry BS, Leeds BS, Virgin Money)
- 1-year fix: 4.4–4.8% AER (Charter Savings, Close Brothers)
- 2-year fix: 4.5–5.0% AER (Atom Bank, Shawbrook)
Fixed-rate Cash ISAs are suitable if you have a firm target date. Check early access penalties — some providers charge 60–90 days' interest to exit early; others do not allow early access at all.
Interest in an ISA is tax-free. At 4.5% AER on £20,000, that is £900/year interest, tax-free. Non-ISA savings accounts use your £500/year Personal Savings Allowance (basic rate) — fine for small balances, but ISAs become advantageous once your savings exceed roughly £11,000 at 4.5%.
3. Help to Save
Help to Save is a government savings scheme specifically for people on low incomes who receive Universal Credit (with earnings) or Working Tax Credit.
How it works:
- Save £1–£50 per month
- After 2 years: HMRC pays a 50% bonus on the highest balance reached — maximum £600 on £1,200 saved
- You can continue for a further 2 years; HMRC pays another 50% bonus on the year 3–4 savings — maximum £600 again
- Maximum total bonus: £1,200 over 4 years
There is no restriction on what you spend the money on — it can go toward a house deposit. Help to Save is available alongside a LISA if you qualify.
On a deposit-saving timeline, the maximum Help to Save amounts (£600–£1,200 in bonuses) are modest but genuinely meaningful. If you are on Universal Credit and saving for a deposit, open a Help to Save account even if the amounts feel small.
4. Employer Salary Sacrifice (Pensions — Indirect Benefit)
Salary sacrifice allows you to give up gross salary in exchange for employer-provided pension contributions, reducing your taxable income.
What salary sacrifice does:
- Reduces income tax paid (you pay less tax on the sacrificed amount)
- Reduces employee NI (saving up to 8% of sacrificed salary for basic rate taxpayers in 2026/27)
- Does not reduce the mortgage-relevant figure — lenders typically assess gross salary before sacrifice for affordability
What salary sacrifice does NOT do:
- It does not create liquid savings you can use for a deposit — sacrificed amounts go into your pension
- You cannot draw from your pension to fund a house deposit (unless you are 55+, and even then tax applies)
However, salary sacrifice has an indirect benefit: if you are currently making employee pension contributions through payroll (not salary sacrifice), converting to salary sacrifice saves you 8% NI on those amounts. A 5% employee contribution on a £35,000 salary (£1,750/year) saves approximately £140/year in NI — that is £140/year redirectable to your deposit fund.
The savings are marginal and depend on your employer offering a salary sacrifice pension arrangement. Speak to your HR department and payroll provider.
5. Investment Accounts (Stocks and Shares ISA)
For timelines under 3 years, equities are unsuitable for deposit savings. Markets can fall 30–40% in a downturn (FTSE 100 fell 33% in early 2020; global equities fell 20%+ in 2022). A market crash in year 2 of your saving plan could delay completion by 18–24 months and force you to buy at a higher-rate, lower-LTV tier.
For timelines of 5+ years, a Stocks and Shares ISA may be appropriate for a portion of your savings. The historical real return on a global equity index fund is 5–7% annually after inflation — above Cash ISA rates. But the keyword is historical: past performance is not a guide to future returns, and equities should only be used when you can genuinely absorb a 2–3 year delay without needing to crystallise losses.
Practical rule: keep your deposit savings in Cash ISA + LISA unless your timeline is genuinely 5+ years.

Assumptions for the comparison table below:
- Annual salary: £35,000 (take-home ~£2,520/month in 2026/27, England, no student loan)
- Monthly savings: £1,200 (47.6% of take-home after rent and living costs)
- Savings vehicle: LISA (£333/month = £4,000/year) + Cash ISA (£867/month at 4.5% AER)
- LISA bonus credited monthly
- Starting balance: £0
| City / Region | FTB avg price | 10% deposit target | Months to target |
|---|---|---|---|
| North East (e.g. Newcastle) | £155,000 | £15,500 | 13 months |
| Sheffield | £185,000 | £18,500 | 15 months |
| Leeds / Bradford | £200,000 | £20,000 | 17 months |
| Manchester | £215,000 | £21,500 | 18 months |
| Cardiff | £195,000 | £19,500 | 16 months |
| Birmingham | £225,000 | £22,500 | 19 months |
| Edinburgh | £245,000 | £24,500 | 20 months |
| Bristol | £285,000 | £28,500 | 24 months |
| South East (e.g. Brighton) | £330,000 | £33,000 | 28 months |
| London | £520,000 | £52,000 | 44 months |
Months rounded to nearest whole month. Includes approximate LISA bonus and Cash ISA interest. Does not include additional buying costs (budget £3,000–£5,000 extra).
The contrast between London and the North East is striking: on the same £35,000 salary and the same savings discipline, a Newcastle buyer can realistically save a 10% deposit in 13 months. The equivalent London buyer faces a 44-month timeline — and that 10% London deposit (£52,000) still leaves them needing to find a mortgage on £468,000, for which £35,000 salary is far too low.

Tip 1: Open a LISA Before You Do Anything Else — Today
The 12-month LISA clock starts from account opening date, not from your first contribution. If you are reading this in June 2026 and you do not have a LISA, open one today — even with a £1 minimum deposit. You will then be able to use it for a property purchase from June 2027 onwards.
Providers: Moneybox (app-based, competitive rates), AJ Bell Dodl, Nutmeg (S&S LISA), Beehive Money, Paragon. Moneybox typically tops the Cash LISA rate tables in 2026 at around 4.75% AER.
Tip 2: Front-Load Your ISA Allowance at the Start of Each Tax Year
The ISA allowance resets on 6 April. If you can maximise your LISA contribution (£4,000) as early as possible after 6 April, your government bonus starts earning interest for the maximum period. Even if you cannot front-load fully, making a lump-sum payment in April rather than spreading monthly contributions from January effectively gains 3 months of additional interest on the bonus.
Tip 3: Reduce Your Biggest Cost First — Rent
For most first-time buyers aged 25–35, rent is the single largest monthly outgoing. The difference between renting alone and house-sharing is often £300–£700/month in major UK cities:
- London: sole-occupier 1-bed from £1,800/month vs room in house share £900–£1,200/month
- Manchester: 1-bed flat from £1,100/month vs room from £600–£750/month
- Leeds: 1-bed flat from £900/month vs room from £500–£650/month
Reducing rent by £400/month by moving to a house share increases your annual deposit savings by £4,800. On a £22,000 target (10% on a £220k property), that is over 5 months shaved from your timeline.
Moving back to a family home temporarily is even more impactful. If you can cover household costs (say £500/month) rather than paying market rent, you might free up £600–£1,000/month for pure deposit savings.
Tip 4: Automate Everything and Pay Yourself First
Do not wait to save what is left at the end of the month — set up a standing order on payday (or within 24 hours of payday) that transfers your monthly savings amount directly into your LISA and Cash ISA. What you do not see, you do not spend.
Set the LISA contribution to go out on the 5th of each month (the day most salaries clear). Set the Cash ISA contribution on the 6th. This means your money is working before rent and bills — not after.
Then build a second standing order to a small "buffer" account (£200–£300/month) for irregular expenses: MOT, dentist, birthday gifts, emergency costs. Without a buffer, a single unexpected £300 cost wipes out a full month's deposit saving.
Tip 5: Review the Numbers Every Six Months and Recalculate
House prices move. Interest rates move. Your salary may increase. Every six months, recalculate:
- What is the current average FTB price in your target area (check Zoopla or Rightmove "sold prices" filtered by flat/terraced)?
- What is your current Cash ISA rate — is a better deal available (you can transfer without losing interest)?
- Has your salary increased? Can you increase the monthly savings amount by even £100?
- Are you on track, behind, or ahead of your timeline?
A 6-monthly review takes 30 minutes and prevents you from arriving at month 18 and realising your target area's prices have moved by 8% and your deposit target has increased by £2,000.
Case Study: Dan and Sarah, Sheffield, Combined Salary £65,000
Dan (£35,000) and Sarah (£30,000) are buying together in Sheffield. They want a 10% deposit on a 2-bedroom property.
Combined take-home (2026/27, England, no student loans):
| Annual | Monthly | |
|---|---|---|
| Dan gross | £35,000 | £2,917 |
| Dan take-home | £27,862 | £2,322 |
| Sarah gross | £30,000 | £2,500 |
| Sarah take-home | £24,284 | £2,024 |
| Combined take-home | £52,146 | £4,346 |
Take-home based on 2026/27 rates: 20% tax above £12,570 personal allowance, 8% NI on £12,570–£50,270.
Monthly outgoings (renting together, 2-bed flat):
| Expense | Monthly |
|---|---|
| Rent (2-bed flat, Sheffield) | £950 |
| Food and household | £450 |
| Utilities (gas, electric, water) | £180 |
| Transport (both cars, insurance, petrol) | £380 |
| Phone, broadband, streaming | £90 |
| Clothes, personal, social | £250 |
| Total outgoings | £2,300 |
| Available to save | £2,046 |
They round down to £2,000/month in combined savings: each opens a LISA (£333/month each = £8,000/year combined, £2,000/year in combined bonuses), and they put the remaining £1,334/month into a joint easy-access Cash ISA at 4.4% AER.
Target: Sheffield 2-bed terraced house, £195,000. 10% deposit = £19,500. Plus buying costs budget: £5,000. Total cash target: £24,500.
| Month | LISA combined (incl bonus) | Cash ISA | Total |
|---|---|---|---|
| 3 | £2,498 | £4,015 | £6,513 |
| 6 | £4,999 | £8,108 | £13,107 |
| 9 | £7,499 | £12,280 | £19,779 |
| 11 | £9,165 | £14,987 | £24,152 |
| 12 | £9,999 | £16,304 | £26,303 |
Dan and Sarah hit their £24,500 cash target in approximately 11 months. They open their LISAs in July 2026, reach their target in June 2027, and begin serious property searching. Because they opened LISAs in July 2026, they will be able to use the LISA funds from July 2027 — aligned perfectly.

The £450,000 LISA property price cap is not an issue in most of England outside the South East. But for buyers in London and parts of the South East targeting properties above £450,000, the LISA becomes unusable for the purchase.
If you open a LISA and later buy a property above £450,000, you must either:
- Leave the LISA savings in the account (they remain, earning interest, for retirement)
- Withdraw with the 25% penalty (recovering less than your original contribution)
If your target property may exceed £450,000:
- Still open a LISA — you lose nothing by opening it, and the property cap may not apply if you end up buying in a cheaper area or buy a smaller property
- Plan your deposit savings primarily through a Cash ISA to maintain flexibility
- Do not rely on LISA funds if you are targeting a London property above £450,000
What Not to Do: Three Common Deposit-Saving Mistakes
Mistake 1: Saving into a current account
A current account pays 0–1% interest. On £15,000 in savings, that is £0–£150/year interest versus £675 in a 4.5% Cash ISA. Move every penny above your £2,000–£3,000 monthly buffer into ISA or LISA accounts.
Mistake 2: Treating the LISA as your only savings vehicle
The LISA is capped at £4,000/year (£333/month). If you are saving £1,500/month, the remaining £1,167 needs to go somewhere — not back into your current account. Open a Cash ISA alongside the LISA from day one.
Mistake 3: Saving for the deposit only and forgetting buying costs
First-time buyers repeatedly arrive at their deposit target and then discover they still need £3,000–£5,000 for solicitors, survey, mortgage arrangement fee, and removal costs. Part 5 of this series covers the full cost breakdown. Build the buying costs into your savings target from the start — do not let them be a surprise.
Deposit Saving Timeline Summary
| Monthly saving | Target: £20,000 | Target: £30,000 | Target: £52,000 (London) |
|---|---|---|---|
| £800/month | 24 months | 36 months | 62 months |
| £1,200/month | 16 months | 24 months | 42 months |
| £1,500/month | 13 months | 19 months | 33 months |
| £2,000/month | 10 months | 15 months | 25 months |
Includes approximate LISA bonus and 4.4% Cash ISA interest. Assumes LISA opened 12+ months prior. Targets exclude buying costs.

Frequently asked questions
How much deposit do I actually need to buy a house in 2026?
The minimum deposit for most residential mortgages in 2026 is 5% (95% LTV products are available from Nationwide, Halifax, HSBC and others). However, a 10% deposit (90% LTV) unlocks significantly better rates — typically 0.5–0.8% lower — and a 15% deposit (85% LTV) reaches the best-value fixed-rate tier. On a £220,000 property (England average outside London), a 5% deposit is £11,000, 10% is £22,000, and 15% is £33,000. In Scotland, average FTB prices are around £195,000 so targets are lower.
Is a Lifetime ISA better than a Cash ISA for saving a deposit?
For most first-time buyers, the answer is both: save up to £4,000/year into a LISA for the 25% government bonus (up to £1,000/year free money), then use a Cash ISA for additional savings up to the £20,000 annual ISA allowance. The LISA bonus is the best guaranteed return available to any UK saver — no investment can reliably beat a guaranteed 25%. The main LISA constraint is the £450,000 property price cap, which makes it less useful if you are buying in London or the South East.
Can I use Help to Save to build a house deposit?
Help to Save is designed for people on Universal Credit or Working Tax Credit, not specifically for house deposits. You save £1–£50/month and after 2 years receive a 50% government bonus on the highest balance reached (up to £600 bonus on £1,200 saved). After 4 years, a further 50% bonus applies on the year 3–4 savings. It is not a house-purchase scheme — there is no restriction on what you use the money for — but the amounts are modest. You can save alongside a LISA if you qualify.
What is salary sacrifice and can it help me save a deposit faster?
Salary sacrifice allows you to redirect pre-tax salary into an employer-provided benefit, reducing your taxable pay. For pension contributions, this reduces income tax and National Insurance — effectively boosting your saving rate. However, sacrificed salary does not create liquid savings — it goes into your pension, which you cannot access for a house deposit. Salary sacrifice can help indirectly: by reducing tax liability, it may increase take-home pay if used efficiently, or free up funds by reducing the pension contributions you make outside of salary sacrifice. It does not directly accelerate cash savings for a deposit.
Should I invest my deposit savings in stocks instead of a Cash ISA?
For deposit timelines under 3 years, no financial adviser would recommend equities for savings earmarked for a specific near-term purchase. Markets can fall 20–40% in a short period (as in 2022 and 2020), and a bad year could push your timeline back by 12–18 months. Cash ISAs at 4.0–4.5% AER and the guaranteed LISA bonus are superior to market risk on a 12–36 month horizon. For timelines of 5+ years, a Stocks and Shares ISA or S&S LISA may generate higher expected returns — but with real downside risk during a market correction.
