The notional SEN budget for mainstream schools: operational guidance 2025 to 2026

Updated 28 November 2024

Applies to England

The Education and Skills Funding Agency (ESFA) closed on 31 March 2025. All activity has moved to the Department for Education (DfE). You should continue to follow this guidance.

1. Introduction

This guidance is primarily for local authorities to help them comply with the requirement to identify for each mainstream school in their area a notional amount to guide schools in their spending to meet the costs, up to 拢6,000 per pupil, of additional support for the school鈥檚 pupils with special educational needs (SEN). Although this is an indicative amount, it is important that it is sufficient for the reasonable additional costs that may be incurred by schools. The guidance will also help schools understand how the amount should be calculated and when it might be appropriate to seek additional resources.

罢丑别听听secures the general presumption in law that children and young people with听SEN听should be educated in mainstream education settings. The Government has made it clear that the general direction of SEND reform is towards establishing a mainstream school and college environment that is more inclusive of children and young people who need specialist SEND provision, and DfE is working on a range of reforms that will facilitate that shift. In the meantime, drawing on the research and examples of existing good practice that have already been published [footnote 1] [footnote 2], local authorities should consider with their schools what changes to local funding arrangements and other developments could be taken forward to support an enhanced role for mainstream schools in making provision for children and young people with more complex needs.

罢丑别听SEND听code of practice, which is statutory guidance to which schools must have regard, sets out more information on mainstream schools鈥 current legal duties in relation to their pupils with听SEN. Those duties include that schools must use their best endeavours to secure that the special educational provision called for by a pupil鈥檚 special educational needs is made.

2. The notional听SEN听产耻诲驳别迟

Mainstream maintained schools and academies (鈥榮chools鈥) are notified each year of a clearly identified but notional SEN budget, within their overall budget allocation. This SEN budget should be used towards the costs of fulfilling their duty to use their 鈥榖est endeavours鈥 to secure that special educational provision for their pupils with听SEN is made. Local authorities are responsible for calculating the amount of this notional budget using funds from the schools block of the dedicated schools grant (DSG), with reference to their local mainstream schools funding formula factors.

The requirement to identify this budget for their schools is set out in regulation 11(3) of the (which is similar to the equivalent regulation for previous years). That regulation requires that:

鈥渢he local authority must identify within each budget share an amount calculated by reference to the requirements, factors and criteria specified in Chapter 1 of Part 3 [that is, the various elements of the local schools funding formula] which are relevant to pupils with special educational needs; such amount must be calculated using a threshold sum of 拢6,000 per pupil below which the school will be expected to meet the additional costs of pupils with special educational needs from its [annual] budget share鈥.

The notional听SEN听产耻诲驳别迟 is not a budget that is separate from a school鈥檚 overall budget. It is an identified amount within a maintained school鈥檚 delegated budget share or an academy鈥檚 general annual grant. It is intended as a guide for a school鈥檚 spending decisions, and is neither a target nor a constraint on a school鈥檚 duty to use its 鈥榖est endeavours鈥 to secure special provision for its pupils with听SEN.

In discharging that responsibility, amongst other expectations set out in the听SEND听code of practice, mainstream schools are expected to:

  • meet the costs of special educational provision for pupils identified as on听SEN听support in accordance with the听SEND听code of practice
  • contribute towards the costs of special educational provision for pupils with high needs (most of whom have education, health and care (EHC) plans), up to the high needs cost threshold set by the regulations (currently 拢6,000 per pupil per annum). This cost threshold applies to the additional costs of provision, above the costs of the basic provision for all pupils in the school. High needs top-up funding is provided above this threshold on a per-pupil basis by the local authority that commissions or agrees the placement

It is important to note that the notional听SEN听产耻诲驳别迟 is not intended to provide 拢6,000 for every pupil with听SEN, as most such pupils鈥 support will cost less than that. Nor is the notional听SEN听产耻诲驳别迟 intended to provide a specific amount per pupil for those with lower additional support costs, although the local authority may make reasonable assumptions about what those costs might be for the purpose of ensuring that their schools鈥 notional听SEN听产耻诲驳别迟 calculation is realistic.

In making assumptions about costs, it is important that local authorities are transparent in their assessment of what provision their mainstream schools should make as part of the local offer of provision for children with SEND. They should identify the resources necessary for schools to deliver both an inclusive environment for their pupils with听SEND听and any more specialist support that is needed. Local authorities must set out in their听SEND听Local Offer information about the arrangements the authority has for funding children and young people with听SEN, including any agreements about how schools will use any budget that has been delegated or devolved to them by the local authority. This statement is relevant to decisions that the local authority makes as to whether it is necessary to issue an听EHC plan.

All schools are expected to make reasonable adjustments for pupils with disabilities, in accordance with their duties under the Equality Act 2010, whether or not they have听SEN. Where a reasonable adjustment is special educational provision, the revenue cost of that adjustment may be met from the school鈥檚听SEN听产耻诲驳别迟.

Schools have a duty to designate a teacher to be the听SEN听co-ordinator (SENCO). We would expect the SENCO to be aware of their school鈥檚 notional听SEN听产耻诲驳别迟 and to be actively engaged with the senior leadership of the school in deciding what to spend on听SEN听support and provision.

3. Calculating the notional听SEN听产耻诲驳别迟

Local authorities are only allowed to use NFF factors in their local funding formulae and must use all NFF factors, except any locally determined premises factors. In 2025 to 2026 local authorities will be required to move their local formulae factors a further 10% closer to the NFF values, compared to where they were in 2024 to 2025, unless they are already mirroring the NFF. Such changes to the local schools funding formula, as well as changes in the costs of special provision mean that local authorities should keep under review how their schools鈥 notional听SEN听产耻诲驳别迟s are calculated and we recommend that all local authorities undertake a check on their calculation for 2025 to 2026. There is currently no national approach to the calculation of schools鈥 notional budget for pupils with听SEN听through the NFF. Local authorities, working with their schools, should therefore continue to use the local formula factor values in accordance with the regulations.

Most local authorities calculate their schools鈥 notional听SEN听产耻诲驳别迟 using a combination of funding from the basic entitlement factor, the deprivation factors, and the low prior attainment factors in the local funding formula. Depending on how the local formula is constructed and the overall weighting of the different formula factors, we would expect the calculation of the notional听SEN听产耻诲驳别迟 to include:

  • a small part of the basic entitlement funding
  • a larger part of deprivation funding, reflecting the higher prevalence of lower-level听SEN听amongst disadvantaged pupils
  • the majority or whole of the low prior attainment factor funding, as this is the best proxy we currently have for pupils with low-cost, high-incidence听SEN

Other elements of the funding formula may also be used 鈥 for example to reflect the prevalence of听SEN听amongst particular groups of pupils such as those who frequently move between schools, as captured by the mobility factor. A proportion of the lump sum could reflect any fixed costs of making听SEN听provision that would apply to all local schools or diseconomies of scale relevant to small schools. In local authorities with a large number of schools that receive a significant element of their funding through the minimum funding guarantee (MFG) element of the local formula, it may be appropriate to include a proportion of this funding in the notional听SEN听产耻诲驳别迟 calculation. This should be kept under regular review, however, as this element of funding usually reduces over time, but could increase in some areas as local authorities move their local formula closer to the NFF. Similarly, it may be appropriate to include a proportion of any minimum per pupil level (MPPL) funding that schools receive in the calculation of the local notional SEN budget, to demonstrate that these schools have sufficient funding for their pupils with SEN.

Local authorities should decide, following discussions and consultation with schools, including in the local schools forum, how big the notional听SEN听产耻诲驳别迟 should be. Local authorities should take into account how many pupils have been identified by schools as in the SEN support category, although these numbers will not have been subject to external moderation and may therefore be inconsistent between schools with pupils who have similar levels of need [footnote 3]. They should also take into account how many are attracting top-up funding to the school (normally those with EHC plans) for whom schools are expected to contribute 拢6,000 per pupil towards the cost of their additional support. Data at local authority level on pupils in the SEN support category and those with EHC plans can be viewed at . Local authorities may need to ask schools for their school level data on SEN support, and also on EHC plans if there are a large number of EHC plan placements from other local authorities. Comparisons with other local authorities鈥 calculations may also be helpful. Local formula data for 2024 to 2025 can be found at schools block funding formulae 2024 to 2025: analysis of local authorities鈥 schools block funding formulae.

As noted above, we recommend that a check of the notional SEN budget calculation for 2025 to 2026 is made in line with this guidance, and that an annual review is carried out subsequently. For 2025 to 2026 we are undertaking a validation check as part of the authority proforma tool (APT) process and ask local authorities to review their calculations if it appears that their total notional SEN budget provides schools with less than 拢1,800 per pupil identified as on SEN support, having deducted 拢6,000 per pupil for whom the school receives top-up funding (normally those with an EHC plan).

4. Targeted funding to supplement the notional听SEN听产耻诲驳别迟

A formulaic calculation of schools鈥 notional听SEN听产耻诲驳别迟s, based on indicators of need used in the formula, is unlikely to be a precise match for the costs of support provided by teachers and other professionals for the pupils they identify as having听SEN.

Any significant mismatch may be an indication that a school鈥檚 approach to identifying pupils鈥櫶SEN听differs markedly from other schools鈥 practice. In some schools, pupils not identified as having听SEN听would be so identified elsewhere. Other schools may too readily identify pupils as having听SEN听when their needs could be met within the normal teaching and learning environment听[footnote 3].

In some cases, however, a significant mismatch between the notional听SEN听产耻诲驳别迟 and actual costs of听SEN听support may be because the school has a disproportionate number of pupils with听SEN听in relation to its size, phase and characteristics, or has pupils with needs of a particular kind that are not captured by the formula factors used. In other cases, a significant mismatch may be because a school鈥檚 small size creates diseconomies of scale in making provision for pupils with听SEN. The local authority can provide targeted funding from its high needs budget to schools in such exceptional circumstances. This funding would supplement the school鈥檚 notional听SEN听产耻诲驳别迟 as calculated under the local funding formula.

Local authorities should carefully consider the criteria for allocating such supplementary targeted funding; simply relying on how schools identify their pupils with听SEN听could lead to perverse incentives. With appropriate criteria in place, however, such funding could be particularly helpful. For example, it might enable a local school to meet the needs of more children with more complex needs instead of them being referred to a special school.

5. Illustrative examples

In tables 1 and 2 below we have provided 2 examples to assist local authorities in reviewing their approach to the calculation of their schools鈥 notional听SEN听产耻诲驳别迟. They are examples that show the calculation of the budget for a primary school of 300 pupils and a secondary school of 1,000 pupils. In these examples we have assumed:

  • that the primary school has a proportion of pupils on听SEN听support and with high needs (such as EHC plans) that are 14% and 3% respectively and that the secondary school has a proportion of pupils on SEN support and with high needs that are 13% and 3% respectively. We have used data published in January 2024 on national averages [footnote 4] for illustrative purposes but, in practice, local authorities should consider the range of percentages in their local schools, as well as the averages across all local schools, in developing their approach, to ensure that schools are given assurance through the notional听SEN听产耻诲驳别迟 that they are receiving sufficient funding for their pupils with听SEN

  • that the costs of special educational provision for a pupil on听SEN听support are, on average, 拢3,500 per annum and the cost of supporting a pupil with high needs is 拢6,000 per annum. In practice, local authorities should consider what are the local average costs of additional special provision for pupils on听SEN听support. As noted above, additional high needs top-up funding should be made available to the school for costs that exceed the 拢6,000 per pupil high needs threshold. Such excess costs should not, therefore, be factored into decisions on the notional听SEN听产耻诲驳别迟.

These examples are illustrative only 鈥 we do not expect local authorities to use the exact calculations below. In developing these illustrative examples, we have considered what level of notional听SEN听产耻诲驳别迟 would be appropriate (given the profile of need and cost assumptions as above) and have based the proportionate contribution of the various formula factors broadly on existing local authority practice. As noted above, in setting their own notional听SEN听产耻诲驳别迟, local authorities should consider the specific profile of need across schools in their local area, as well as the extent to which they are protected by MFG and MPPL funding.

The examples below use 2025 to 2026 NFF factor values, before the application of the area cost adjustment (ACA). The notional听SEN听产耻诲驳别迟 contribution percentages should be consistently applied across each phase of education.

  3. For primary and secondary schools, the national average proportion of pupils with high needs (EHC plans) is 3% and 听2.7% respectively. For these examples, however, we have rounded the latter percentage up to 3%. For primary schools, the national average proportion of pupils on SEN support is 14.1%. For the primary school example, however, we have rounded this percentage to 14%. We have used the national average proportion of pupils on SEN support in secondary schools of 12.9% and rounded that to 13% in the secondary school illustrative example.听
