How to write a grant sustainability plan that holds up

The deadline’s close, the budget’s nearly agreed, and one question is still staring back: what happens when the grant funding ends? You’re trying to write a sustainability plan for the grant while chasing approvals and remembering there’s a life outside this application.

Funders rarely expect permanent delivery. What they want is a credible next step, backed by costs, evidence and decisions your team can stand behind.

What is a grant sustainability plan and what should it cover?

A grant sustainability plan explains how a project’s benefits, services or learning will continue after grant funding ends. It identifies what will remain, who will take responsibility, what it will cost and how those costs will be covered.

When drafting your grant proposal, start with the funder’s requirements. Then set out confirmed resources, potential income, partner commitments and decision dates before the project period ends. Include what happens if further funding doesn’t arrive.

Why this matters

Winning brings relief, and then delivery starts, payroll carries on and the next funding deadline appears, which is exactly when an unplanned ending starts to bite.

A sustainability question asks whether you’ve thought beyond the award. Depending on the scheme, assessors may want confidence that services can continue, assets will be maintained or learning will remain useful.

Read the actual requirements. Guidance for government grants and other schemes can differ, so check the rules before writing your grant proposal. The National Lottery Heritage Grants guidance, covering awards of £10,000 to £250,000, illustrates why programme-specific guidance matters. A heritage project’s ongoing obligations won’t necessarily resemble those of a community support service.

Your answer also protects your organisation’s financial health. Unsupported promises can leave delivery teams managing commitments that the budget never covered.

Before drafting, check your application against funder priorities. A plan for long-term sustainability should preserve the change the funder wants, which may mean letting some original activities go.

A credible plan gives assessors something they can check. It also gives your team a shared view of what they’ve agreed to deliver.

Decide what continues after the grant

A grant sustainability plan usually needs to address four dimensions: programme delivery, finance, collaborative partnerships and internal capacity. Start with delivery and capacity before chasing another funding source.

For programmatic sustainability, use your strategic plan to decide what should continue: the full service, a smaller offer, a trained workforce, maintained equipment or accessible research findings?

Name the beneficiaries, delivery level and intended duration. Explain what will stop, too.

For a pilot, continuation might depend on evaluation results. Say what evidence would justify further delivery and who will make that decision.

Be careful with “the project will become embedded”. Explain where it will sit, which existing service will take responsibility and whether that service has agreed.

Training colleagues is a form of capacity building that can reduce dependence on one funded post. It still needs supervision, refresher training, written procedures and time in someone’s workload.

Volunteers need support, expenses and safeguarding arrangements where relevant. Their goodwill doesn’t remove those costs.

Capture knowledge before fixed-term staff leave. Name who maintains records, equipment, licences and delivery guidance.

If writing these answers exposes a team skills gap, practical bid team training can help people test commitments earlier, so the final draft doesn’t become everyone’s first proper discussion about delivery.

Cost the work that remains

A continuation plan needs its own cost calculation. Copying the grant budget won’t show what happens afterwards or provide a realistic operating budget.

Cost the service level you’ve just defined. Include staffing, employer on-costs, supervision, premises, insurance, accessibility, maintenance, evaluation and reporting where relevant.

Separate one-off setup costs from recurring expenditure. Equipment purchased during the award may still need servicing or replacement later.

Keep the full delivery cost distinct from what a particular funder will pay. The National Lottery Community Fund’s project overheads guidance is useful when checking how shared organisational costs are treated.

Your continuation budget must cover necessary costs, even when the next grant excludes them.

Funding approval and money arriving in the bank usually happen on different dates, which can affect financial stability.

Check whether payments arrive upfront, in stages or after expenditure. Compare those dates with payroll, supplier deposits and annual bills.

Use grant management controls to track commitments and cash flow, and ask finance to confirm any proposed bridge funding. Don’t describe unrestricted reserves as available simply because they appear in the accounts.

The Charity Commission recommends linking reserves policy with strategic and financial planning in its charities and reserves guidance. For charities in England and Wales, check affordability and financial health before promising to absorb a funding gap.

Separate secured income and confirm partner commitments

Diversified revenue sources can reduce dependence on one award. They also create work, costs and uncertainty.

Individual donors, corporate sponsorships, government grants, further grants and commissioned services may all have a place. Choose options that suit your purpose and delivery model.

Record prospective funding streams in a schedule, noting each funding source’s status clearly.

Income status	What your plan should show
Confirmed	Approved amount, restrictions, evidence and payment dates
Pending	Amount requested, submission status and expected decision date
Planned	Named opportunity, eligibility check, owner and application date
Earned income	Pricing basis, demand evidence, delivery costs and expected net contribution
In-kind support	Agreed contribution, duration, valuation basis and any conditions

Keep potential income labelled as potential all the way through, so it doesn’t quietly become guaranteed halfway through the narrative.

The National Lottery funding directory can help identify relevant schemes. Finding an opportunity is only the first step; check current eligibility, timing and whether grant funding supports continuation.

For donations, use your actual fundraising performance rather than an unexplained growth target. For paid services, test demand and affordability, especially where charges could exclude the people you’re trying to support.

Cost the fundraising effort itself. Applications, donor management and sales activity need someone’s time.

A sensible mix of revenue streams is one your organisation can manage, with enough lead time to act before the current award ends.

“We’ll work with local partners” leaves an assessor with unanswered questions. Which partners? What will they do, and for how long?

For each partner, record the contribution, responsible role, start date and end date. Distinguish a supportive conversation from an authorised commitment.

Use memorandums of understanding to record delivery arrangements, although they won’t count as proof of committed funding. Ask for evidence that matches the promise.

For a handover, confirm staffing, safeguarding, referrals, data responsibilities and asset ownership. A receiving organisation needs both authority and capacity to accept the work.

Check your award terms before transferring equipment, changing delivery or generating income. The government’s grant agreement requirements explain how grant agreements set objectives, conditions, monitoring and financial provisions for government grants.

Those requirements guide government grant-making, while your own agreement sets out your actual obligations.

There isn’t one universal UK rule for programme income or reinvestment. Good grant management means checking your agreement and getting consent where needed, even if last year’s arrangements seemed to allow it.

Use evidence to make decisions before the money runs out

Any case for future funding rests on evidence, which helps show whether continued delivery is justified, supporting sound decisions and operational resilience as circumstances change.

A logic model links resources, activities, outputs and intended outcomes. Outputs describe what you delivered; outcomes describe the change that followed.

UKRI’s logic model guidance explains how these models set out how a programme is expected to work.

Use the logic model to decide what to retain and which evidence supports continuation. A busy activity isn’t automatically the part that produces the strongest results.

Set SMART goals (specific, measurable, achievable, relevant and time-bound), with measures and starting points chosen before delivery begins. Then compare results with the change promised in the application, including the limits of what your evidence can demonstrate.

Your evaluation plan should identify who collects information, checks quality, reviews results and reports to the funder.

Keep the workload proportionate. Follow-up after the award ends needs staff time, access to records and suitable data arrangements. Cost it before promising it.

Collect balanced evidence, including missed targets and feedback from people who leave early where practical.

Set a review point before funding applications need to be submitted. Otherwise, useful findings may arrive after the decision they were meant to support.

If results change materially, tell the funder in line with the award conditions. Explain the position, proposed action and next review date.

You can write a credible grant sustainability plan without confirmed replacement grant funding. Set out clear conditions and actions.

Work backwards from the award end date, setting decision dates during the project period. Allow time for funding decisions, staff consultation, referrals, contractual notices and approvals.

Use three possible routes: continue, reduce or close. Set the dates and financial thresholds with finance and delivery leads. Set a review date and evidence threshold in the evaluation plan to trigger each route.

Route	Decision trigger	Action to describe
Continue	Required funding, delivery capacity and evidence against the logic model are confirmed	Approve the ongoing service and budget
Reduce	Resources support a smaller, safe offer	Apply agreed eligibility, capacity and referral arrangements
Close or hand over	Minimum safe delivery requirements aren’t met	Notify affected people and complete the agreed transition

A smaller offer still needs adequate supervision and safeguarding. Cutting sessions while keeping every other promise may save less than expected.

A fallback plan is only usable if its decision date leaves enough time to act safely.

Name who authorises each route. Avoid “the team will decide” when trustees, directors, commissioners or funders must approve changes.

Responsible closure may include participant communications, onward referrals, staff arrangements, final reporting, records retention and permitted asset disposal. The award ending doesn’t erase those responsibilities.

Turn the plan into a clear sustainability answer

Start with the funder’s sustainability section, its question and word limit. A clear grant sustainability plan brings the evidence together so assessors can follow your decision without searching across attachments. They assess the answer within the wider grant proposal, so make the reasoning easy to follow.

Open by stating what will remain after funding ends and who will own it. Then explain the cost in relation to your operating budget, confirmed resources and any gap.

Describe potential funding and other revenue streams by status, decision date and named owner. Finish with the review process and fallback.

These sentence openings can help organise a first draft:

“Our priority after the award is to retain…”

“The continuing cost is based on…”

“The confirmed contribution covers…”

“The remaining funding requirement will be reviewed by…”

“If sufficient funding isn’t confirmed by the agreed decision date…”

Complete each statement using approved facts. A sentence starter gets you going, and the evidence behind it is what makes the commitment stand up. Record each commitment and its supporting evidence in your grant management process.

Compare weak and stronger wording. “We will seek further funding” gives little confidence. Naming the opportunity, amount required, application owner and expected decision date gives the assessor something to assess. A logic model can show how promised outcomes inform continuation decisions.

Where space is tight, prioritise delivery level, financial position and fallback. Keep detailed calculations in the permitted supporting material, with clear references.

The aim is an answer whose commitments an assessor can check, whatever its length.

Avoid common mistakes and check your commitments

The most familiar weakness is treating future funding, including government grants, as the entire strategy. If that funding doesn’t come through, the application has no answer.

Another is describing income growth without showing the basis. A fundraising target needs supporting performance, capacity and timing.

Watch for cost savings that move work onto already stretched colleagues. “Existing staff will absorb this” needs management approval and a workload check.

Partner letters can also promise less than the narrative suggests. A general letter of support won’t carry the weight of a funded post, free venue or agreed handover.

Don’t count the same contribution twice or treat restricted money as generally available. Keep confirmed, pending and planned income consistent across the budget and written answer.

Finally, avoid claiming success from activity counts alone. Attendance can show reach, and lasting change needs its own evidence.

These gaps often appear under deadline pressure. Bring finance, delivery and bid leads together before submission. It’s easier to correct an assumption whilst it’s still in a document.

Review the sustainability section against one agreed version of the application and budget. Ask the people responsible to confirm these points.

• Every continuing activity has an owner, delivery level and cost.
• Confirmed, pending and planned income are clearly separated.
• Partner contributions are supported by appropriate evidence.
• Cash arrival dates match delivery commitments.
• Decision dates leave time for reduction, handover or closure.
• The evaluation plan, reporting and ongoing obligations are funded.
• Continuing costs are affordable and support your organisation’s financial health.

Resolve disagreements before polishing the wording. A neat paragraph can’t settle an unapproved financial commitment.

Keep supporting approvals and calculations together in your grant management records. Your team will need them after submission, particularly if the person who wrote the answer moves on.
