SEN Funding: Understanding High-Needs Funding and EHCP Costs at School Level

Ask most headteachers what confuses them about SEND and money, and it’s rarely “identifying need” or “writing a good provision map.” It’s usually some version of: where does this money actually come from, who decides how much, and why does it never quite stretch far enough. That confusion isn’t a gap in your understanding. SEN funding in England moves through several different pots, calculated by different bodies, on different timetables, using terminology that hasn’t been explained properly to most people who now have to manage it. Layer a genuinely severe national funding crisis on top of that, and it’s no surprise that budget-setting season now carries as much anxiety about high needs as it does about staffing.

This piece sets out how the money actually flows, what that means for realistic budgeting, why the pressure you’re feeling is a national story rather than a local failure, and some practical ways to make funding go further without compromising provision. It draws on current Department for Education (DfE) guidance and recent reporting on the high needs funding system — all of it dated, all of it linked at the end, because these figures move.

How SEN funding actually flows: three layers, not one pot

The biggest source of confusion is that people talk about “SEN funding” as if it’s a single grant that arrives with a pupil. It isn’t. It’s three distinct layers, funded from two different national funding blocks, calculated and paid by two different organisations, on two different rhythms.

Element 1: the money already in your core budget

Every mainstream pupil on your roll brings core, per-pupil funding into your school through the Schools Block of the Dedicated Schools Grant (DSG), calculated via the national funding formula (NFF). This is sometimes referred to as Element 1. It isn’t SEN funding as such, but it’s the base your whole budget sits on, including the general capacity you use to differentiate teaching, run intervention groups and support pupils who don’t have a formal SEN status at all. Element 1 matters here because it’s the first thing LAs and DfE guidance point to when discussing what schools are already expected to fund from their own resources.

Element 2: your notional SEN budget, and the £6,000 threshold

This is where most of the confusion lives. Every mainstream school has a “notional SEN budget” — not a separate pot of cash sitting in a different account, but an amount identified within your existing delegated budget, calculated by the LA using local funding formula factors (things like prior attainment, deprivation and other need-related measures). It’s an indicative figure, not a ring-fenced allowance.

DfE’s current operational guidance sets a mandatory threshold of £6,000 per pupil per year: schools are expected to meet the additional costs of SEN support up to that amount from their own delegated budget, before any high needs top-up funding from the LA applies. This isn’t a suggestion — DfE guidance is explicit that it functions as a threshold below which the school is expected to meet the cost itself. As of the guidance updated in January 2026, that £6,000 figure remains current, but you should treat it as something to verify every year, not assume carries over automatically.

Two things trip up even experienced SBMs here. First, £6,000 is not a per-pupil entitlement — the same guidance is explicit that it isn’t intended to provide £6,000 for every pupil with SEN, because most pupils’ support costs considerably less than that (DfE guidance elsewhere references an average SEN support cost closer to £3,500 a year). Second, the notional budget is a planning figure for the LA to use when setting your overall delegated budget, not a spending cap or a spending guarantee — you can spend more or less than your notional allocation on SEN support, and nobody claws back the difference. What actually matters for your own financial planning is what you’re really spending against what you’re really receiving, not the notional figure on a spreadsheet.

Element 3: high needs top-up funding

Once a pupil’s additional costs genuinely exceed that £6,000 threshold — almost always a pupil with an Education, Health and Care Plan (EHCP), though not exclusively — the LA can agree “top-up” funding, paid from the High Needs Block of the DSG rather than the Schools Block. This is Element 3.

Critically, there’s no national formula for this. Each LA designs its own approach, and most now use a banded model: an EHCP’s assessed level of need is matched to a funding band, and each band carries a fixed top-up value, reviewed at each pupil’s annual review in line with the SEND Code of Practice. Bands, values and the number of bands in use vary significantly between authorities — a Band 3 in one LA bears no necessary relationship to a Band 3 next door. If you work across a trust with schools in more than one LA, this is worth spelling out to your finance committee explicitly, because “the same EHCP need” can attract very different top-up values depending purely on postcode.

Specialist placements and EHCP-specific costs

Pupils placed in special schools, resourced provision or specialist units are usually funded differently again, through an agreed place-funding element (a base amount per commissioned place) plus a top-up on the same principle as mainstream. The exact place-funding figures are set locally and nationally negotiated year to year, so rather than quote a number here that may already be out of date by the time you read this, check your LA’s current high needs funding policy directly — every LA is required to publish one, usually alongside its schools forum papers.

What this means for budgeting realistically

Understanding the three layers is only useful if it changes how you plan. A few things worth building into your process:

• Track actual SEN spend separately from the notional figure. The notional budget tells you what the LA assumed when setting your overall delegation, not what you’ll actually spend. Schools with a higher-than-average proportion of SEN support pupils routinely spend well above their notional figure from general funds, because the notional calculation is formula-driven, not needs-driven at individual pupil level.
• Plan for a funding lag. Top-up funding doesn’t start the moment a need becomes apparent. Between a request for an Education, Health and Care Needs Assessment (EHCNA) and an agreed, funded EHCP, you’re commonly looking at months, sometimes well beyond the twenty-week statutory timescale that LAs are supposed to meet but frequently don’t, given the pressures described below. Your school is expected to keep funding provision up to the £6,000 threshold throughout that period regardless of where the paperwork has got to.
• Budget for in-year growth, not just September numbers. Pupils with high needs move schools in-year more often than the general population, particularly at points of family or placement breakdown. Your high needs income for the year should never be treated as fixed at the September census.
• One-off assessment and specialist costs sit outside top-up funding. Educational psychologist reports, occupational therapy assessments, specialist equipment and staff training are frequently funded separately, or not at all, and vary by LA policy. Don’t assume top-up funding is designed to absorb these.
• Understand your LA’s specific top-up review cycle. If bands are reviewed annually at the EHCP annual review, a change in a pupil’s presentation partway through the year won’t automatically trigger a change in funding — you may be carrying a cost increase for months before the banding catches up, or conversely receiving funding for a level of need that’s since reduced.

None of this is a criticism of your finance systems. It’s simply that SEN and high needs income behaves differently to almost every other funding line schools manage, and treating it like a fixed annual grant is where budgets come unstuck.

The national picture: this is a genuine crisis, not a leadership failure

If your high needs budget feels impossibly tight, it’s worth knowing clearly that this is a well-documented, sector-wide funding crisis, not a sign you’re managing it worse than anyone else.

Local authorities have been permitted since 2020 to keep high needs overspends — the gap between what they receive in High Needs Block funding and what EHCP and SEN provision actually costs across their area — off their main council balance sheets, through a temporary accounting mechanism known as the statutory override. The Local Government Association (LGA) has reported that this cumulative national deficit reached billions of pounds, with the vast majority of councils responding to LGA surveys reporting a Dedicated Schools Grant deficit and warning of insolvency risk once the override ends. The override was originally due to lapse in March 2026; the government has since extended it, alongside a commitment to write off around 90% of councils’ historic SEND deficits accrued up to the end of 2025-26, leaving councils responsible for the remaining 10% and for managing costs going forward under a revised arrangement running to March 2028.

On top of that, the DfE took the unusual step of temporarily suspending the high needs national funding formula for 2026-27 — the mechanism normally used to calculate how much high needs funding each LA receives — and instead rolled forward each LA’s 2025-26 allocation with adjustments for pay and National Insurance costs, holding total national high needs funding at roughly £12 billion for the year. The department has said it will review the allocation methodology once wider SEND system reforms, expected in early 2026, are set out.

What that means in practice: the system you’re budgeting against is genuinely mid-reform, genuinely under-resourced relative to demand, and genuinely being reworked at a level well above your LA. Your SEND team at the LA is very likely managing the same pressure from the other direction — rising EHCP requests, a funding formula that’s paused rather than settled, and a deficit position their own council leadership is anxious about. That context doesn’t fix your budget, but it should change the conversation you have with governors: this isn’t “why can’t we manage this,” it’s “how do we manage well inside a system that’s under strain nationally.”

Making the funding stretch further

There’s no version of this that makes high needs funding pressure disappear. But there are things within a school’s control that genuinely help.

Invest early, and invest in what’s evidenced

The strongest lever most schools have is reducing the number of pupils whose needs escalate to EHCP level in the first place, through early, well-targeted SEN support funded from Element 1 and Element 2. That means a SENCO with real time allocated to identify need early rather than react to crisis, evidence-based interventions rather than a scattergun of resources, and a genuine graduated response — assess, plan, do, review — that’s followed consistently rather than treated as paperwork. This isn’t about avoiding legitimate EHCP requests to save money; a school that under-identifies need stores up bigger problems, and LAs and Ofsted’s area SEND inspections both look unfavourably on schools that appear to be gatekeeping assessment. It’s about making sure the support a child gets at SEN support stage is good enough that fewer children need to go further, and that when an EHCNA request is made, it’s well-evidenced and moves faster because the groundwork is already there.

Build a genuine working relationship with your LA’s SEND team

Schools that treat the LA SEND team purely as a gatekeeper to fight tend to have a harder time than schools that build a working relationship with them. That means understanding your LA’s local banding framework and funding policy in detail rather than only encountering it when a decision goes against you, engaging early and constructively in annual reviews rather than only at crisis points, and being a reliable, well-evidenced applicant — an LA officer managing a large caseload under deficit pressure will, understandably, move faster and more favourably for schools whose paperwork is consistently thorough and whose requests are consistently proportionate.

Get your own data right

Know your actual SEN and high needs spend against your notional budget and top-up income, not just at year-end but through the year, broken down by pupil where appropriate so you can see where costs are concentrated. This is what lets you have an evidenced conversation with your LA when top-up funding genuinely doesn’t cover a placement, and it’s what lets you brief governors accurately rather than defensively.

Being honest with governors about the financial reality

Governors and trustees carry real fiduciary responsibility for your budget, and SEN and high needs costs are one of the most common sources of in-year budget variance in schools right now. Being straightforward with them early serves you better than presenting a tidy budget in September and explaining an overspend in March.

A few things worth building into how you report:

• Show SEN and high needs spend as its own clearly labelled line in budget monitoring reports, distinct from general staffing, so governors can see the trend rather than have it absorbed into a general variance.
• Be explicit about the gap, if there is one, between notional SEN budget, actual SEN support spend, and top-up income received — and explain why that gap exists, rather than letting it look like a management failure.
• Flag pupils in the pipeline — EHCNA requests submitted, annual reviews due, placements likely to change — as a forward risk register item, not just a current-year cost.
• Name the national context plainly. Governors who understand that high needs funding is under acknowledged national strain, with LAs themselves running deficits and a national formula currently on hold, are far better placed to support difficult in-year decisions than governors who think the pressure is unique to your school.
• Where a decision genuinely has no good option — reducing non-EHCP intervention provision to protect statutory EHCP costs, for instance — bring that to governors as a real choice with real trade-offs, rather than making it quietly and hoping nobody asks.

None of this makes the underlying pressure smaller. But a governing body that understands the mechanics and the national context is a governing body that can back you when you need to make a hard call, and that’s worth the extra time it takes to explain it properly.

The bottom line

SEN funding is genuinely complicated, not because anyone is trying to make it hard to understand, but because it sits across three funding layers, two different funding blocks, locally variable banding models, and a national system that’s currently being held together with a temporary accounting override while a bigger reform is worked out. Understanding the mechanics — what’s yours to fund up to £6,000, what the LA funds above it, how top-up banding actually works locally, and why the deficit picture nationally is as severe as it is — won’t make the money go further on its own. But it will make your budgeting more accurate, your LA conversations more productive, and your governors better equipped to support you through what is, for almost every school in the country right now, a genuinely difficult financial picture rather than a local one.
