Eligibility normally looks at gross household income, while the affordability assessment works from income left after tax, National Insurance, student-loan deductions, existing commitments, rent and service charges. A regulated adviser then tests the mortgage, essential spending and the provider’s required surplus to determine a sustainable share.
The exact threshold depends on the product and location. Homes England grant-funded guidance uses an £80,000 gross household-income limit, while the standard consumer scheme information states £80,000 outside London and £90,000 in London. Those figures should not be combined into one universal rule.

What “household income” means for shared ownership
For the Homes England grant-funded shared ownership programme in England, the first question is whether the household is eligible. The test is based on gross income before tax and other deductions. It is not the same calculation used to decide how much mortgage and shared-ownership equity a household can safely afford.

Relevant household members are generally included even when they are not applying jointly or becoming owners. That prevents a household from omitting a partner or other permanent resident simply because only one person will be named on the lease. The guidance identifies exceptions, including children under 18, people in full-time education and people whose residence is not expected to be permanent.

Eligibility thresholds depend on the scheme
| Rule set | Published gross household-income threshold | Geographic or programme scope |
|---|---|---|
| Homes England grant-funded guidance | £80,000 or less | England grant-funded shared ownership guidance |
| GOV.UK standard shared ownership eligibility information | £80,000 outside London | England, outside London |
| GOV.UK standard shared ownership eligibility information | £90,000 in London | London |
The apparent difference reflects different descriptions of the scheme rather than a calculation error. Before relying on a threshold, identify the funding programme, the property’s location and the provider’s current policy. Homes England’s 2026 guidance is for England; Wales, Scotland and Northern Ireland have separate arrangements.
Which income counts in the eligibility test?
Start with each relevant household member’s gross annual income. This can include employment income, self-employment income, pensions and other regular income. The guidance does not say that every benefit is automatically included or excluded, so the adviser and provider must apply the relevant rules to the circumstances.
Benefits and payments
Some amounts may be excluded where they are intended for a particular purpose or are being used for continuing health or care costs. The guidance gives examples that can include certain disability benefits, fostering allowance, adoption pay and child maintenance. It specifically states that child benefit is included in the household-income threshold test.
For affordability, lenders may treat benefits differently from the eligibility test. A benefit that helps establish eligibility may not be accepted as mortgage income, or may be accepted only with evidence of its duration. Conversely, a lender’s policy may accept a benefit that needs a different treatment in the eligibility calculation. Ask the regulated adviser to identify the lender policy being used rather than assuming one blanket benefits rule.
Future changes and capital
Known, evidenced changes should be considered. Examples include a planned reduction in working hours, maternity or paternity leave, an imminent promotion or a confirmed return to work. Capital and access to capital can also matter, as can income generated by savings or investments. The adviser may need statements, employment evidence or other documentation to establish whether a change is real and when it will occur.
Sole and joint applications
In a permitted sole application, the sole applicant’s finances are used for the affordability calculation. The gross household-income eligibility test can still include relevant household members. In a joint application, every applicant becomes a legal owner, and the affordability assessment uses the applicants’ combined financial circumstances.
How the detailed affordability calculation works
Homes England’s current method is a budget exercise rather than a simple salary multiple. The adviser starts with gross income, removes deductions and commitments, accounts for non-mortgage housing costs, then tests the mortgage and the household’s remaining budget.

Stage A: establish gross household income
The adviser records the income used for the eligibility test and identifies which parts are dependable for borrowing. Gross salary is not the same as take-home pay: tax, National Insurance, pension contributions and student-loan deductions are considered later in the budget.
Stages B and C: remove deductions and commitments
Income tax, National Insurance and student-loan deductions reduce the amount available for mortgage purposes. Existing loans, credit-card payments, finance agreements, maintenance commitments and childcare are then recorded. A lender may verify balances and monthly payments through statements or credit information, so leaving out a commitment can produce an inaccurate result.
Stage D: include rent and service charges
The calculation includes non-mortgage housing costs that will continue after purchase. This includes rent on the share still owned by the landlord and the property’s service charge. Depending on the lease, estate charges, management fees, buildings insurance and other recurring charges may also affect the budget.
Stage E: calculate the mortgage-purpose income
After the deductions, commitments and non-mortgage housing costs are removed, the remaining figure is the income available for mortgage purposes. It is this remainder—not gross salary—that provides the base for the mortgage-payment test.

The mortgage payment should generally be no more than 30% of the net income remaining for mortgage purposes. The 30% figure is a benchmark, not an absolute legal cap. A higher percentage can be considered when the adviser can justify it, the applicant agrees and the provider’s minimum-surplus requirement is still met. An applicant does not have to accept a share that requires exceeding the benchmark.
Stage G: test essential spending and surplus
The adviser subtracts essential expenditure from the mortgage-purpose income after the proposed mortgage payment. The amount left must exceed the provider’s published minimum surplus-income policy. Providers retain the final purchase decision, so passing a generic online borrowing calculator does not establish an eligible share.
A worked example of the budget method
Suppose a household has illustrative monthly gross income of £5,000. After tax, National Insurance and a student-loan deduction, £1,250 is removed. Existing credit and childcare commitments total £450, while rent and service charges for the proposed home total £1,000. The mortgage-purpose income is therefore £2,300:
£5,000 − £1,250 − £450 − £1,000 = £2,300

Thirty per cent of £2,300 is £690, so that is the benchmark mortgage payment. If essential spending is £1,350, the post-mortgage remainder would be £260. Whether that is sufficient depends on the provider’s minimum-surplus policy. This example is only an illustration of the sequence; providers set their own surplus requirements and the adviser must use the applicant’s real figures.
How rent on the unsold share is tested
Shared ownership buyers pay rent on the equity retained by the landlord. The affordability assessment must account for that rent over time, not only on the first day of ownership. Homes England’s guide says rent should be stress-tested for five years using the assumptions in the relevant Key Information Document.
The guide describes annual increases of 5% for CPI-based leases and 6% for RPI-based leases. Its example starts with rent equal to 2.75% of the unsold equity. Under the stated assumptions, that initial rate would stress-test to 3.51% after five years for the CPI case or 3.68% for the RPI case. These are assessment assumptions, not a promise that every lease will charge those exact increases.
A larger initial share can reduce rent because less equity remains unsold, but it also requires a larger deposit and mortgage. The adviser therefore tests the complete package rather than treating the rent as a minor add-on.
Costs that belong in the affordability picture
- Mortgage payment: the payment on the share being purchased, assessed under the lender’s affordability and stress-testing rules.
- Rent: the payment on the landlord’s unsold equity, including the five-year stress assumption.
- Service charge: the regular charge for maintaining shared areas and services.
- Sinking-fund contributions: Right to Shared Ownership guidance identifies contributions toward major works as a cost to consider.
- Estate and management charges: these depend on the property and lease.
- Buildings insurance and repairs: responsibility varies by lease and should be confirmed before applying.
- Buying and moving costs: legal fees, mortgage fees, valuation costs, removals and other one-off expenses reduce the savings buffer even when they are not monthly commitments.
When comparing homes, separate recurring monthly costs from one-off purchase costs. A home with a lower mortgage can still require more cash each month if its rent or service charge is higher.
What the adviser and provider each do
Homes England requires a qualified, experienced adviser regulated to give mortgage advice to assess whether a mortgage is available and what amount is suitable. The adviser should understand shared ownership and have access to an appropriate lender range. The adviser’s budget planner should be populated with the applicant’s actual expenditure figures.
Rank #4
ONS figures can help benchmark or clarify spending. They may replace an actual figure when an applicant has no current expenditure for an essential item or when costs are expected to change, but they should not ordinarily replace the applicant’s real figures. Known future commitments—such as childcare, a vehicle or equipment needed for work, or support for a child in education—must be considered.
The provider publishes relevant policies, including its minimum surplus-income policy, and makes the final decision on the purchase. The regulated adviser determines the appropriate mortgage assessment; the provider decides whether the proposed purchase and share meet its rules.

That assessment uses the landlord’s estimated home value and the applicant’s finances, and tests whether mortgage, rent and service-charge payments can be sustained.
Preparing accurate figures before the appointment
- List every household member, their expected residence and whether they will apply and become a legal owner.
- Record gross annual income separately for salary, self-employment, pension, benefits and other sources.
- Collect payslips, tax records, benefit evidence, bank statements and documents showing any confirmed future change.
- List tax, National Insurance and student-loan deductions, then document loans, credit cards, finance agreements, maintenance and childcare.
- Obtain the property’s rent, service charge, estate charge, sinking-fund information and any stated rent-escalation assumptions.
- Write down actual essential spending on food, utilities, transport, insurance, communications, healthcare and other necessities.
- Calculate the deposit, legal and moving costs, and the savings buffer that will remain after completion.
- Ask the adviser to show the mortgage-payment percentage, five-year rent stress test and resulting surplus for each share being considered.
A household budget workbook can organise these figures, but it does not produce an official result or replace regulated advice.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Comparing two homes or two offered shares
Compare both options using the same assumptions. The relevant questions are:
- How much deposit and mortgage does each share require?
- What is the current rent on unsold equity, and what is its five-year stress-tested amount?
- What are the current service, estate, management and sinking-fund charges?
- How much essential monthly spending remains after the move?
- What surplus remains under the provider’s policy?
- How much savings remain after the deposit and buying costs?
- Does the lease or programme vintage assign different repair, insurance or major-works responsibilities?
Buying the largest suitable share can reduce rent, but retaining reasonable savings for emergencies and future service-charge increases is also part of a sustainable decision. The “largest” share is not automatically the safest share.

The survey’s household-income measure includes benefits and assumes all household members contribute to costs. That descriptive method should not be confused with the Homes England adviser-led affordability calculation.
Common mistakes and how to avoid them
Using take-home pay for the eligibility threshold
The eligibility test is based on gross household income. Take-home pay becomes relevant to the later affordability budget after specified deductions are removed.
Assuming only the named applicant counts
Relevant household members can count toward gross household income even when they do not apply jointly. Check the residence and permanence exceptions rather than omitting someone automatically.
Treating all benefits the same
Eligibility guidance identifies particular exclusions and includes child benefit, while lenders apply their own evidence and sustainability rules. Have the adviser assess each payment separately.
Ignoring rent increases or service charges
The mortgage is only one part of the housing cost. Include rent on unsold equity, service charges and any sinking-fund or estate costs, then review the five-year stress test.
Relying on a salary multiple or online calculator
The current method is a budget calculation with an essential-spending and surplus test. An online figure cannot account reliably for the lease, provider policy or the household’s actual commitments.
Presenting an old percentage rule as current
The previous Homes England affordability calculator and earlier 25%–45% housing-cost guidance have been withdrawn. Use the current adviser-led method and identify the applicable programme version.

Bottom line for applicants
Think of shared ownership affordability as two gates. First, establish gross household income under the correct scheme and location threshold. Then build a realistic budget: subtract deductions, commitments, rent and service charges; test the mortgage against the 30% benchmark; include essential spending and future costs; and verify that the remaining surplus meets the provider’s policy. A regulated adviser and the provider—not a generic calculator—determine whether the proposed share is sustainable.
