Eligibility

Who qualifies as a key worker?

Key workers include anyone employed in a public sector or essential service role. This covers NHS workers, teachers, police officers, firefighters, social workers, armed forces personnel, and foster carers. Some specialist lenders also extend their criteria to civilian support roles. If you are not sure whether you qualify, speak to one of our advisers and we will check for you.

Schemes for Key Workers

Government Schemes That Could Help You Buy

Buying your first home as a key worker? Several government schemes can help make homeownership more affordable. Whether you are considering Shared Ownership, Right to Buy, or the First Homes Scheme, we can advise on which option suits your circumstances and search the whole of market to find the right mortgage to support it.

1

Shared Ownership

Buy a share of a home (often between 10% and 75%) and pay rent on the rest. You can staircase to full ownership over time as your income grows.

2

Right to Buy

Council tenants can purchase their home from the local authority, often at a significant discount that can act as your deposit.

3

First Homes Scheme

New-build homes sold at a minimum 30% discount to local first-time buyers. The discount is preserved for future owners too.

4

Bad Credit Options

We work with lenders who consider applicants with CCJs, defaults, IVAs, or other adverse credit history. Don't rule yourself out.

Schemes and Eligibility

Key Worker Mortgage Schemes and What They Really Offer

Ask ten people what a key worker scheme is and you will get ten different answers, which is exactly why so many nurses, teachers and police officers give up before they start. The honest picture is more encouraging than the confusion suggests. There is no single government key worker mortgage scheme, but there is a genuine set of specialist mortgage schemes, enhanced borrowing rules and lender incentives behind the key worker mortgages we arrange every week, and together they can move you onto the property ladder sooner. Here is what exists, who is eligible, and how we use it.

Is There an Official Key Worker Scheme?

Not in the way most people expect. The old national key worker scheme closed years ago, and the Help to Buy equity loan shut to new applicants in March 2023. What replaced it is a patchwork: shared ownership through a housing association, the First Homes scheme with its minimum 30% discount, Right to Buy for council tenants, and Forces Help to Buy for serving personnel. Alongside those available schemes sit the specialist mortgage schemes run by individual mortgage lenders, which are never advertised as a key worker mortgage scheme at all. There is no shrink wrapped NHS mortgage or teacher product sitting on a shelf either. They are simply criteria, and criteria are where a good mortgage broker earns their keep.

Key Worker Status and Eligibility Criteria

Your key worker status is decided by the lender, not by a government list, so the eligibility criteria vary depending on who you approach. Most treat NHS clinical staff, teachers, police officers, fire service and prison service employees, and other public service workers as key workers. Some go further and include civilian support roles, laboratory staff and local authority teams. What matters just as much is your employment status: whether your employment contract is permanent, fixed term, bank or agency changes which doors open. Fewer lenders will consider a three month probation period, for example, but several will, and knowing which ones saves you a wasted application.

Enhanced Borrowing and Your Borrowing Potential

This is where the significant difference usually shows up. Standard mortgages are typically capped around 4.5 times income. For certain professions, a handful of lenders stretch to 5 or even 5.5 times, and a few will treat newly qualified doctors and dentists more generously still. Enhanced borrowing of that kind can change your borrowing potential by tens of thousands of pounds. Just as important is what counts as income at all: unsocial hours payments, overtime, bank shifts and London weighting are treated very differently from one lender to the next. Try our mortgage borrowing calculator for a rough idea, then let us check it properly.

Deposits, Free Valuations and Additional Perks

A smaller deposit is not the barrier it once was. Mortgages at 95% loan to value are widely available, so a 5% deposit is a realistic starting point, and a large deposit tends to unlock lower interest rates rather than being a requirement in itself. Watch the incentives too. Cashback or free valuations are common additional perks, and some popular lenders bundle both. They are worth real money, though a headline freebie on a poor interest rate is no bargain. Fixed and variable rate mortgages each have a place here, and the right answer depends on how much certainty you want over your monthly repayments.

The Mortgage Application Process, Step by Step

The application process is far less daunting when someone else is steering it. We start with a free consultation and a decision in principle, which costs nothing and gives you a credible position when you make an offer. Before a full mortgage application goes in, we gather the evidence lenders actually want: three months of payslips and bank statements, proof of any allowances, your employment contract and, for self employed key workers, two years of accounts. Getting those documents right first time is the single biggest thing that stops a case stalling. From there we handle the paperwork, chase the surveyor and keep you updated until completion. Whether you are among the first time buyers taking a first step or remortgaging a home you have owned for a decade, the process is the same, and as a fee free mortgage broker our advice costs you nothing.
