Saving Your Deposit: How Long It Really Takes in 2026 (FTB Guide, Part 1)
Realistic timeline for saving a house deposit in 2026: average UK prices, savings rates, LISA bonus, and how to shave years off the process.
Welcome to "Buying Your First Home" — Part 1: Saving the Deposit
This is Part 1 of our five-part guide for first-time buyers in 2026. We start at the very beginning: the deposit. Before mortgages, solicitors and surveys, you need cash — and working out exactly how much, and how long it will realistically take to accumulate it, is the foundation of any credible homebuying plan.
This guide gives you real numbers, not aspirational ones.

UK house prices vary enormously by region. Here are the figures that matter for first-time buyers planning a purchase in 2026:
| Region | Average house price (FTB properties) | 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 West | £210,000 | £10,500 | £21,000 | £31,500 |
| North East | £155,000 | £7,750 | £15,500 | £23,250 |
| Scotland | £195,000 | £9,750 | £19,500 | £29,250 |
| Wales | £200,000 | £10,000 | £20,000 | £30,000 |
| England average (excl London) | £220,000 | £11,000 | £22,000 | £33,000 |

The deposit you should actually target depends on your local market. In most regions outside London, a 10% deposit (90% LTV) is the realistic first-time buyer sweet spot: it unlocks a much wider product range than 95% LTV and gives lenders confidence without requiring years of additional saving. In London, many FTBs start with 5% on a Help to Buy substitute scheme or Shared Ownership.
Why the difference between 5%, 10% and 15% LTV matters
The mortgage rate differential between LTV bands is significant:
| LTV | Typical 5-year fix (2026) | Monthly payment (£200k mortgage, 25yr) | Extra monthly cost vs 85% LTV |
|---|---|---|---|
| 95% LTV | 5.2–5.8% | £1,295–£1,370 | £120–£195 |
| 90% LTV | 4.6–5.0% | £1,205–£1,260 | £30–£85 |
| 85% LTV | 4.3–4.7% | £1,175–£1,220 | — |
On a £200,000 mortgage, the difference between 95% and 85% LTV can be £120–£195/month — over a five-year fix, that is £7,200–£11,700 in extra interest. This is why accumulating that extra 5–10% deposit is often worth delaying completion by six to twelve months.
How long will it take? Month-by-month savings table
Assumptions: saving £2,000/month into a combination of Cash ISA (4.5% AER) and LISA (4.5% AER + 25% bonus on LISA portion), starting from £0. LISA capped at £4,000/year contribution (£333/month), remainder into Cash ISA.
| Month | LISA balance (incl bonus) | Cash ISA balance | Total saved | Notes |
|---|---|---|---|---|
| 1 | £417 | £1,667 | £2,083 | First LISA bonus not yet credited |
| 3 | £1,250 | £5,047 | £6,297 | Running well |
| 6 | £2,500 + £625 bonus | £10,147 | £13,272 | LISA 6-month bonus credited |
| 9 | £3,750 + £938 bonus | £15,297 | £19,985 | — |
| 11 | £4,000 + £1,000 bonus | £18,031 | £23,031 | Year 1 LISA maxed |
| 12 | £4,167 (yr 2 starts) | £18,697 | £22,864* | *ISA only in month 12 while LISA resets |
| 14 | £4,833 + £1,208 bonus | £21,447 | £27,489 | Approaching 10% on £275k property |
| 18 | £6,250 + £1,563 bonus | £27,097 | £34,910 | 10% on £350k reached |
| 24 | £8,333 + £2,083 bonus | £35,998 | £46,414 | 15% on £310k property |
Note: LISA bonus is paid monthly by most providers. The table above shows approximate running totals; exact figures depend on the provider's bonus schedule and interest compounding.
At £2,000/month saving, a first-time buyer targeting a £220,000 property (10% deposit = £22,000) reaches their goal in approximately 11 months.
The LISA: £1,000 a year in free money
The Lifetime ISA is the single most powerful savings tool for first-time buyers under 40.
How it works:
- Open between ages 18 and 39 (can contribute until age 50)
- Save up to £4,000/year
- HMRC adds 25% bonus — so a £4,000 contribution becomes £5,000
- Interest or investment growth applies to the full £5,000
Rules for using a LISA to buy a home:
- Property must cost £450,000 or less (at purchase price — not relevant post-completion)
- Must be a first-time buyer (you cannot have owned a home in the UK or abroad previously)
- Account must have been open for at least 12 months before use
- The LISA funds must go directly to your solicitor, not to you
What you lose if you withdraw for any other reason: HMRC imposes a 25% withdrawal charge — which is not a flat 25% return of your bonus, but 25% of the total withdrawal amount. On £5,000 (£4,000 + £1,000 bonus), a withdrawal penalty of £1,250 means you receive £3,750 — worse than if you'd never contributed. The LISA is exclusively for first home or retirement.
Stocks and Shares LISA vs Cash LISA: for timelines under four years, a Cash LISA (currently paying 4.0–5.0% AER at leading providers) is lower-risk than an S&S LISA. If you're five or more years away from buying, an S&S LISA may offer higher expected returns but with volatility risk.

Lifetime ISA calculatorFour strategies to save faster
1. Maximise the LISA first, every April
The £4,000 LISA limit resets on 6 April each year. If you can fund the full £4,000 early in the tax year, your bonus starts compounding immediately. Front-loading the LISA by early May each year maximises the interest on both your £4,000 and the £1,000 bonus.
2. Use a high-interest Cash ISA for the remainder
In 2026, easy-access Cash ISAs are paying 4.0–4.5% AER. Fixed-rate Cash ISAs (1–2 year terms) are paying 4.4–5.0% AER. If you have certainty about your target completion date, a fixed-rate ISA maximises interest — but check the early closure penalties if plans change.
3. Cut the largest discretionary spend first
The biggest lever is almost always rent. House-sharing rather than renting alone can save £300–£700/month in most UK cities — that is £3,600–£8,400/year directly addable to the deposit fund. If parental support is available (staying with family temporarily), this can accelerate timelines by 12–18 months.
4. Ask about employer match on pension — then redirect savings
If your employer matches pension contributions above the minimum, maximising that match effectively increases your total compensation — freeing more take-home pay for the deposit fund. It's worth checking your pension offer document before deciding how aggressively to save versus invest in the pension.
Regional comparison: where's fastest to save?
Saving the same amount (£1,500/month) from a £38,000 salary (take-home ~£2,780/month), how long does a 10% deposit take in different cities?
| City | Avg FTB price | 10% deposit target | Months to save | Notes |
|---|---|---|---|---|
| Sheffield | £185,000 | £18,500 | 12 months | Fastest major city |
| Leeds | £200,000 | £20,000 | 13 months | Strong market |
| Manchester | £215,000 | £21,500 | 14 months | High demand |
| Cardiff | £195,000 | £19,500 | 13 months | No SDLT for FTBs under £225k |
| Birmingham | £220,000 | £22,000 | 15 months | — |
| Bristol | £285,000 | £28,500 | 19 months | Rapid price growth |
| London | £520,000 | £52,000 | 35 months | 5% deposit: 17 months |
Assumes LISA bonus on £4,000/year. Months rounded to nearest whole month. No starting balance.
The contrast is stark: a Sheffield buyer on £38k can realistically save a 10% deposit in one year. The equivalent buyer in London takes nearly three years — and faces a much larger absolute number.
Case study: Priya, 26, Manchester, £38,000 salary
Priya works as a marketing executive in Manchester. She earns £38,000/year and is determined to buy her first flat.
Priya's take-home pay (2026/27, England, Plan 2 student loan):
| Annual | Monthly | |
|---|---|---|
| Gross salary | £38,000 | £3,167 |
| Income Tax (20%) | −£5,086 | −£424 |
| NI (8%) | −£2,034 | −£170 |
| Plan 2 student loan (9% above £28,470) | −£864 | −£72 |
| Take-home | £30,016 | £2,501 |
Priya's monthly budget:
| Expense | Monthly cost |
|---|---|
| Room in house share | £650 |
| Food | £280 |
| Transport (bus pass + occasional Uber) | £90 |
| Utilities (included in rent) | £0 |
| Phone + broadband | £45 |
| Streaming + subscriptions | £25 |
| Clothes + misc | £100 |
| Total essential + lifestyle | £1,190 |
| Available to save | £1,311 |
Priya rounds her savings to £1,300/month: £333/month into her LISA (£4,000/year, claiming £1,000 bonus), and £967/month into a fixed-rate Cash ISA at 4.8% AER.
Priya's deposit timeline for a £215,000 flat in Manchester:
Target: 10% deposit = £21,500
| Month | LISA (incl bonus) | Cash ISA | Total |
|---|---|---|---|
| 6 | £2,498 | £5,880 | £8,378 |
| 12 | £4,999 + £1,000 bonus | £11,970 | £17,969 |
| 14 | £5,832 | £13,902 | £19,734 |
| 15 | £6,248 | £14,874 | £21,122 |
Priya reaches her 10% deposit target in approximately 15 months from starting. She opens her LISA and Cash ISA in May 2026 and is ready to begin serious property searching by August 2027.
She also checks whether Shared Ownership might get her into a property sooner — buying a 40% share (£86,000) would require only £8,600 deposit at 10%, achievable in under seven months. However, she prefers to own outright and decides to continue saving.

Mortgage affordability check — see what lenders will offerShared Ownership as an alternative path
If the deposit timeline is prohibitive, Shared Ownership allows you to buy a fraction of a new-build or resale property while paying rent on the portion you don't own.
How it works in 2026:
- Buy between 10% and 75% of a property from a housing association
- Pay a mortgage on your share and subsidised rent on the remainder
- The minimum share dropped from 25% to 10% in the 2021 reforms
- Stamp duty is paid on the share purchase (and on the rest only if you "staircase" to 80%+)
Worked example: £250,000 property, 25% share
| Full purchase | Shared Ownership (25%) | |
|---|---|---|
| Purchase price | £250,000 | £62,500 |
| 10% deposit | £25,000 | £6,250 |
| Mortgage | £225,000 | £56,250 |
| Monthly mortgage (4.6%, 25yr) | £1,247 | £312 |
| Monthly rent (2.75% on 75%) | — | £430 |
| Total monthly housing cost | £1,247 | £742 |
The Shared Ownership route allows someone saving £700/month to accumulate the £6,250 deposit in under nine months, then start buying with a lower total housing cost than a full purchase mortgage. The trade-off: the rent charge doesn't build equity, and future "staircasing" (buying more shares) is subject to current market valuations.

Frequently asked questions
How much deposit do I need to buy a house in 2026?
The minimum deposit for a residential mortgage in 2026 is typically 5% (with 95% LTV products available from several lenders). However, a 10% deposit (90% LTV) gives you access to significantly better rates — typically 0.5–1% lower — and a 15% deposit (85% LTV) is where the best two-year and five-year fixed rates sit. On an average English property outside London (£220,000), a 5% deposit is £11,000, a 10% deposit is £22,000, and a 15% deposit is £33,000.
How does the Lifetime ISA help first-time buyers?
The Lifetime ISA allows you to save up to £4,000 per year and receive a 25% government bonus (up to £1,000/year). To use a LISA for a home purchase, the property must cost £450,000 or less, you must be a first-time buyer, and the account must have been open for at least 12 months. Over three years of maximum saving, you receive £3,000 in free bonus contributions.
What is the fastest realistic timeline to save a deposit in 2026?
On £38,000 salary with take-home of approximately £2,850/month, saving £1,500/month into a Cash ISA at 4.5% and a LISA, a first-time buyer targeting a £220,000 property (£22,000 deposit at 10%) could realistically reach their goal in around 13–14 months if starting from scratch — or 11–12 months with the £1,000 LISA bonus.
Can I use Shared Ownership as an alternative to a full deposit?
Yes. Shared Ownership allows you to buy a share (10–75%) of a property and pay rent on the remainder. The deposit and mortgage are based on the share price, not the full property value. On a £250,000 property with a 25% share, the purchase price is £62,500 — and a 10% deposit is just £6,250. This dramatically reduces the savings target, though you'll pay both a mortgage and rent.
Is a Cash ISA or Lifetime ISA better for saving a deposit?
Use both if you can. Save up to £4,000 into a LISA for the 25% bonus, then fill the remaining £16,000 of your annual ISA allowance with a Cash ISA. The LISA bonus is worth at least 25% on your contribution — far outstripping any savings rate. The main restriction is the £450,000 property price cap, so in London you may not be able to use the LISA if targeting higher-value properties.
