The main options at a glance
First-time buyer help comes in three forms: savings incentives (the Lifetime ISA), tax reliefs (stamp duty relief) and ownership schemes (shared ownership, plus local or lender products). They are not mutually exclusive: a firefighter might save into a Lifetime ISA, use the bonus for a deposit, buy under the stamp duty threshold and apply for a mortgage that accepts their overtime.
The table below summarises what we verified on GOV.UK. Everything else (key worker priority, developer offers, local authority schemes, lender products) varies by area and time, so we describe how to check rather than promise availability. Nothing here is regulated financial advice; for your own situation speak to a qualified mortgage adviser.
Start with numbers: your take-home pay, how much deposit you can save, and the price range you are considering. Use the pay calculator for take-home and the mortgage borrowing calculator for borrowing.
| Option | Key rule | Applies to |
|---|---|---|
| Lifetime ISA | 25% bonus, up to £1,000 a year on up to £4,000; first payment before 40; payments to 50 | UK savers; counts in £20,000 ISA allowance for 2026/27 |
| Stamp duty relief | 0% to £300,000; 5% on £300,001 to £500,000; no relief above £500,000 | England and Northern Ireland first-time buyers |
| Shared ownership | Household income up to £80,000 (£90,000 London); cannot afford full deposit and mortgage | England |
| Armed forces priority | Serving and veteran armed forces prioritised in competitive situations | Shared ownership, England |
| Key-worker help | Not a national GOV.UK shared ownership rule; local and lender schemes vary | Check locally |
Scotland (LBTT) and Wales (LTT) have their own property taxes and schemes. Verify current rules before acting.
The Lifetime ISA: how much it could add
GOV.UK says you can put up to £4,000 a year into a Lifetime ISA until you are 50, and the Government adds a 25% bonus, up to a maximum of £1,000 a year. You must make your first payment before you are 40, and the Lifetime ISA counts towards the overall £20,000 ISA allowance in 2026/27. It can hold cash or stocks and shares, or both.
Worked example. A firefighter saves £333.33 a month (£4,000 a year). The bonus adds £1,000 a year, so £5,000 goes in each year. After 5 years that is £20,000 of your own money plus £5,000 of bonus, £25,000 before any interest or investment growth. To reach £4,000 a year from take-home of £2,376 a month (competent firefighter, see below), the saving is 14% of net pay, so it is a real commitment.
Important conditions apply to withdrawals: the standard rules say money must be used for a first home within a price cap (we understand £450,000) or after age 60, otherwise a 25% withdrawal charge applies. GOV.UK's summary page we checked did not restate the cap or charge, so confirm both in the linked eligibility pages before opening an account. The purchase generally must use a conveyancer and a mortgage, and the account usually needs to be open for a minimum period.

In 2026 the Government announced that it intends to replace the Lifetime ISA with a new first-time buyer ISA. Commentary at the time of the January 2026 announcement said the new product would be restricted to first-time buyers, would pay its bonus when you buy rather than on each deposit, and that existing Lifetime ISA holders should be able to keep using their accounts. A consultation followed, and reporting puts the launch in April 2028 at the earliest.
This is not law yet, and the details (bonus size, age limits, withdrawal charges, transition rules) are unconfirmed. Do not delay a purchase or a savings plan solely on the basis of a future scheme. If you already have a Lifetime ISA, do not close it without understanding the withdrawal charge; if you are thinking of opening one, check current announcements first.
We will update this guide as details are confirmed. For now the practical approach is to plan with the rules that exist today and keep an eye on GOV.UK for the transition arrangements.
Stamp duty relief and total buying costs
For first-time buyers in England and Northern Ireland, GOV.UK's rates show 0% on the first £300,000 and 5% on the portion between £300,001 and £500,000. Above £500,000 the relief is not available and standard rates apply. You must be a first-time buyer, as must anyone you buy with. The standard rates for others are 0% to £125,000, 2% to £250,000 and 5% to £925,000.
Worked examples. A £250,000 first home: SDLT £0. A £320,000 home: 5% of the £20,000 above £300,000 = £1,000. A £400,000 home: 5% of £100,000 = £5,000. A £520,000 home: no relief, so standard rates apply: 2% on £125,000 (£2,500) plus 5% on £270,000 (£13,500) = £16,000. Scotland and Wales use different taxes, so if you are buying there check the local rates and reliefs.
Stamp duty is only one cost. Budget for legal fees, a survey, mortgage fees, moving and immediate repairs. As a rule of thumb, allow a few thousand pounds beyond the deposit; the exact figure depends on the price and property. The budgeting guide shows how to build a target and timeline.
| Purchase price | SDLT with first-time buyer relief | SDLT without relief (standard rates) |
|---|---|---|
| £250,000 | £0 | £2,500 |
| £300,000 | £0 | £5,000 |
| £400,000 | £5,000 | £10,000 |
| £500,000 | £10,000 | £15,000 |
| £520,000 | £16,000 (no relief above £500,000) | £16,000 |
Standard rates: 0% to £125,000, 2% £125,001 to £250,000, 5% £250,001 to £925,000. Higher rates apply for additional properties or non-UK residents. Check GOV.UK's calculator for your purchase.
Shared ownership: what firefighters should know
Shared ownership lets you buy a share of a home and pay rent on the rest. GOV.UK says your household income must not exceed £80,000 (or £90,000 in London), and you must not be able to afford all the deposit and mortgage payments for a home that meets your needs. You also need to meet one of several conditions, for example being a first-time buyer or having previously owned but being unable to afford a home now. Firefighter household incomes are usually well below the cap.
GOV.UK notes that armed forces members, both serving and veterans, receive prioritisation in competitive situations. The page we checked did not list a national key-worker priority, so do not assume that being a firefighter gives priority. Some housing providers, developers or local authorities do run key-worker allocations for particular developments, so ask each provider directly and get the rule in writing.
Illustration. Buying a 40% share of a £250,000 home means a share value of £100,000; your mortgage and deposit apply to that share, and you pay rent on the remaining 60%. Costs beyond the mortgage include rent, service charges and maintenance, so compare the full monthly cost with buying outright and with renting. You can 'staircase' to buy more shares later, which has its own costs.
Local, employer and lender help for key workers
Beyond national schemes there are local authority key-worker housing programmes, employer schemes and lender products aimed at emergency services or key workers. These change often, differ by area and can be limited to particular developments. We do not list specific schemes here because we could not verify them all, and outdated schemes can mislead.
How to check: ask your fire and rescue service HR or benefits team what they know about local key-worker housing, check your local council's housing pages, and ask any developer whether they have key-worker or emergency-services allocations. Ask mortgage brokers whether any lenders treat emergency services staff differently, and get specifics such as how overtime is treated.
Also consider whether your Fire Brigades Union branch or service welfare team has information; see FBU membership. Above all, compare the total cost over time, not only the headline discount.
A worked savings plan on firefighter take-home pay
A competent firefighter on £40,358 in England with 12.59% pension takes home £28,512.50 a year, or £2,376.04 a month, on the site's 2026/27 calculation before student loan. Saving £333.33 a month into a Lifetime ISA would be 14.0% of that. A development firefighter on £31,539 takes home £1,952.46 a month, so £333.33 is 17.1%.
Using overtime. If you work overtime, remember that overtime is taxed at 20% plus 8% NI for a basic-rate firefighter, so £1,000 of overtime is £720 in hand (less student loan if applicable). Directing £3,000 of gross overtime a year (£2,160 net) to a deposit adds £180 a month. With the Lifetime ISA bonus on the first £4,000, the same money goes further. Try the overtime to deposit tool for your own numbers.
A simple timeline: target deposit ÷ (monthly saving + bonus). For a £20,000 deposit (10% of £200,000) at £333.33 a month plus a £83.33 monthly bonus equivalent, you would need roughly 48 months (£416.66 x 48 = £20,000). Interest would shorten this slightly; stopping and starting would lengthen it.

The order matters. Fix your finances first (budget, credit file, commitments), then decide the route (Lifetime ISA, shared ownership, standard mortgage). Start saving into the right wrappers early, because the Lifetime ISA rules include timing conditions. Then talk to a broker, and only then view properties within a range you can afford.
If you are early in your career, remember that pay rises from development to competent will change affordability; see pay progression. If you plan to marry or buy jointly, both incomes count and both must qualify for first-time buyer relief. For the mortgage side see the mortgage guide, and for a structured pack use the mortgage readiness tool or the mortgage pack.
- Work out take-home pay and a comfortable monthly saving.
- Decide on the wrapper: Lifetime ISA, cash ISA or other savings, checking the rules.
- Check your credit file and reduce commitments.
- Gather payslips, P60 and overtime evidence for lenders.
- Compare routes: standard mortgage, shared ownership, key-worker offers.
- Budget for stamp duty, legal, survey and moving costs.
- Speak to a qualified adviser before committing.
Frequently asked questions
What help is there for first-time buyers who are firefighters?
Nationally: the Lifetime ISA (25% bonus up to £1,000 a year), stamp duty relief up to £300,000 in England and Northern Ireland, and shared ownership in England. There is no national scheme reserved for firefighters. Some local, employer or lender schemes support key workers, so ask your service and brokers.
How does the Lifetime ISA work for a first home?
You can save up to £4,000 a year and the Government adds 25%, up to £1,000 a year, with the first payment made before age 40 (GOV.UK). Withdrawals for other purposes normally carry a charge, so check the current first-home rules and price cap before relying on it.
Is the Lifetime ISA being scrapped?
The Government announced in 2026 that it plans to replace it with a first-time buyer ISA. It was at consultation stage when we checked, with reports of a launch around April 2028, and details are unconfirmed. Existing holders are expected to be able to keep using their accounts.
Do first-time buyers pay stamp duty?
In England and Northern Ireland, first-time buyers pay 0% up to £300,000 and 5% on the portion between £300,001 and £500,000, per GOV.UK. Above £500,000 the relief is lost. Scotland and Wales charge different taxes, so check the rules where you are buying.
Do firefighters get priority for shared ownership?
GOV.UK's shared ownership page mentions priority for armed forces members but does not list a national key-worker priority. Some developers or housing providers run key-worker allocations locally, so ask them directly and get the rules in writing. Household income must not exceed £80,000 (£90,000 in London).
How long does it take to save a deposit on firefighter pay?
It depends on the price and your saving rate. Saving £333.33 a month into a Lifetime ISA with the bonus is about £416.66 a month, so a £20,000 deposit takes roughly 48 months before interest. Using overtime can shorten that; the overtime to deposit tool shows your numbers.
Should I wait for the new first-time buyer ISA?
Probably not solely for that. The details are unconfirmed and a launch is reported for 2028 at the earliest. Plan around the rules that exist today, do not close an existing Lifetime ISA without checking the charges, and watch GOV.UK for announcements.
