This follows months of negotiations after a first-ever defeat of a Welsh Government Supplementary Budget on 14 July.<\/p>\n<p>This deal confirms all of the prior spending additions proposed in the First Supplementary Budget, while adding an additional \u00a360 million for Additional Learning Needs, a policy area which had been a priority for Labour.<\/p>\n<p><strong>The Origin of the Deal<\/strong><\/p>\n<p>As is often the case in the mid-year for Welsh budgets, additional monies from UK government spending topped up the pot via two \u2018Barnett consequentials\u2019:<\/p>\n<ul>\n<li><strong>\u00a3327 million<\/strong> from the UK Government\u2019s 2026 Spring Statement \u2013 most of which came from writing off accumulated Special Educational Needs and Disabilities (SEND)-related deficits held by English local authorities<\/li>\n<li><strong>\u00a346 million <\/strong>from the UK Government\u2019s Main Estimates.<\/li>\n<\/ul>\n<p>Along with other smaller allocations, this increased the amount of day-to-day spending available in 2026-27 by approximately <strong>\u00a3411<\/strong> <strong>million<\/strong>.<\/p>\n<p>Back in July, it was the new government\u2019s intentions to spend these additional monies on the NHS, childcare and public transport \u2013 and since that vote was simply about spending additional cash, in many ways it was a low-stakes vote. Because the 2026-27 <strong><em>annual <\/em><\/strong>budget approved in January by the previous Labour government remained in force, the <strong><em>supplementary<\/em><\/strong> budget vote would not have resulted in spending cuts, a government shutdown, or a new election. What this deal secures is the legal authority to spend these new allocations; it can also be seen perhaps as a trial-run for the 2027-28 Annual Budget that will be voted on this winter, where failure would be far more significant.<\/p>\n<p><strong>Additional Learning Needs: The Crux of the Deal<\/strong><\/p>\n<p>The original proposal did not include additional spending for ALN, and before the July vote, Labour sought \u00a3100 million in 2026-27. The Welsh Government countered with an offer of \u00a340 million per year for two years (\u00a380 million total), an offer which was extended to a third year of funding (\u00a3120 million total) in the final offer before the vote.<\/p>\n<p>The deal provides <strong>\u00a360 million<\/strong> for ALN in 2026-27, of which \u00a344.8 million will go directly to schools, \u00a311.2 million to local authorities, \u00a32.5 million to further education and \u00a31.5 million towards developing a long-term sustainability plan.<\/p>\n<p>Although no figure has been announced for subsequent years, the accompanying <a href=\"https:\/\/www.gov.wales\/written-statement-developing-sustainable-additional-learning-needs-aln-system\">ministerial statement<\/a> notes that <em>\u201cfunding allocations for ALN for future years will be considered as part of our preparations for the Draft Budget for 2027-28, in the context of a need to reach cross-party support\u201d.<\/em><\/p>\n<p>Although adult and children<strong>\u2019<\/strong>s social care remains the most acute pressure facing local authorities, ALN spending is clearly an enormous budgetary challenge. Ministers say ALN spending has grown <a href=\"https:\/\/www.walesonline.co.uk\/news\/politics\/row-welsh-government-given-340m-34176256\">2.5 times faster<\/a> than overall education spending over the last decade and is heading towards <a href=\"https:\/\/www.audit.wales\/news\/additional-learning-needs-system-under-strain\">\u00a31 billion per year<\/a>. In that context, in the absence of wider reform or definitive commitments regarding future funding, this can best be seen as a stopgap measure.<\/p>\n<p>The deal also does not appear to have resolved the trade dispute declared by NAHT Cymru and ASCL Cymru in July, which covers pay as well as ALN.<\/p>\n<p><strong>The NHS<\/strong><\/p>\n<p>Allocations for the NHS from the proposal remain the same: <strong>\u00a3145 million<\/strong> including \u00a3100m in day-to-day spending for waiting times and elective care, \u00a325m for surgical and diagnostic hubs, and \u00a320m capital for maintenance.<\/p>\n<p>The usual caveats from our <a href=\"https:\/\/blogs.cardiff.ac.uk\/thinking-wales\/the-first-supplementary-budget-what-it-means-and-the-options-ahead\/\">previous budget analysis<\/a> apply: Because of significant in-year spending on reducing waiting lists last year, core NHS spending was previously set to fall by 1.2% in real terms this year, and even after this \u00a3100 million uplift, it is still set to fall by roughly <strong>0.4% in real terms.<\/strong><\/p>\n<p><strong>Childcare<\/strong><\/p>\n<p>The deal confirms <strong>\u00a355 million (\u00a345m revenue and \u00a310m capital)<\/strong> to extend 12.5 hours of funded childcare per week to all two-year-olds, completing the Flying Start expansion first announced in the 2021 Co-operation Agreement. The government describes this as a first step towards Plaid\u2019s pledge of <strong>20 hours a week for all children aged nine months to four years, for up to 48 weeks a year<\/strong>.<\/p>\n<p>Together with smaller commitments to bus services, free school meals in secondary schools and school swimming, these allocations total <strong>\u00a3224 million <\/strong>in day-to-day spending \u2013 shown in the accompanying figure. This leaves <strong>\u00a3187 million<\/strong> of additional resource funding unallocated, which could be used to address other spending pressures later in the financial year.<\/p>\n<p><strong><em>Changes to Unallocated Day-to-Day (Resource) Spending \u00a0<\/em><\/strong><\/p>\n<figure id=\"post-2323 media-2323\" class=\"image align-none\"><img decoding=\"async\" src=\"http:\/\/blogs.cardiff.ac.uk\/thinking-wales\/wp-content\/uploads\/sites\/509\/2026\/10\/Picture1-scaled.png\" alt=\"\" \/><\/figure>\n<p>&nbsp;<\/p>\n<p><strong>What does it mean for 2027-28?<\/strong><\/p>\n<p>The main significance of this agreement is political. It shows that Plaid and Labour can reach a deal and that ALN is a bridge to wider budget cooperation, albeit after a very extended period of negotiation. The 2027-28 Budget, worth around \u00a327 billion, is the much bigger test. The Plaid Cymru administration will need to show that it can make additional progress on its major childcare commitments in a budget in which calls for funding will be intense in every single department.<\/p>\n<p>Beyond the political calculations, there is one very real indicator that should be flashing red on the Welsh Government\u2019s budget dashboard.<\/p>\n<p><strong>Inflation is once again squeezing public budgets worldwide<\/strong><\/p>\n<p>Unlike previous rounds of inflation which had multiple causes, the unexpected jump in prices in 2026 has one primary cause: a global energy price shock linked to the conflict in Iran. Before the start of this war, CPI inflation was expected to ease to around 2% from April and stay there for the rest of the year. Because of significantly higher gas, petrol and diesel prices, and because the UK is a net energy importer, inflation reached 3.1% in August, up from 2.9% in July. The Bank of England now <a href=\"https:\/\/www.bankofengland.co.uk\/speech\/2026\/september\/clare-lombardelli-speech-at-the-sixth-biennial-conference-poland\">expects <\/a>it to rise to around 3.7% in 2026 Q4 and around 4.2% in 2027 Q1.<\/p>\n<p>The Institute for Fiscal Studies\u2019 <a href=\"https:\/\/ifs.org.uk\/system\/files\/2026-10\/IFS_Green_Budget_2026_0.pdf\">Green Budget<\/a>, published on 12 October, quantifies the effects of that higher inflation for the public sector. The new Chancellor, John Healey, inherited spending plans that already looked incredibly tight before prices began rising faster than expected. The IFS calculates that simply keeping departments whole for higher pay costs could require an additional \u00a33 billion of budget pressure in 2028-29, and if future pay awards follow recent forecasts for average earnings growth, this pressure could reach \u00a37-9 billion. Meanwhile, the effects of higher inflation on the non-pay components of department budgets could reduce the value of non-pay day-to-day budgets by \u00a34-8 billion in 2028-29 and the value of capital budgets by \u00a32-4 billion (IFS Green Budget 2026, p168).<\/p>\n<p>For Wales, while we cannot calculate the impact directly (because the Welsh Government\u2019s block grant follows spending decisions for England under the Barnett formula), how far the Chancellor tops up English departments for inflation later this month will largely determine what reaches Cardiff Bay. This matters, because the previous Welsh Government\u2019s 2026-27 budget promised every department at least the same funding in real terms as the prior year, including an uplift for inflation and pay, and councils and NHS bodies across Wales have warned that their funding isn\u2019t rising enough to cover higher costs. Earlier this year, in our <a href=\"https:\/\/www.cardiff.ac.uk\/wales-governance-centre\/publications\/finance\">elections analysis<\/a> work funded by the Nuffield Foundation, we cautioned that a tough spending outlook will make improving services especially difficult for the new Welsh Government.<\/p>\n<p><strong>\u201cWinter is Coming\u201d<\/strong><\/p>\n<p>The Supplementary Budget agreement is a useful, if modest, milestone. It gives the Welsh Government the legal authority to spend new in-year monies. But a one-time \u00a360 million for ALN is a stopgap rather than a settlement, and the deal leaves the wider budgetary pressures largely unresolved.<\/p>\n<p>The real test is still to come. The 2027-28 Budget will be far larger and far less forgiving, with childcare commitments to fund, pressure in every department, and inflation driving up what pay and services cost. Much will depend on how the Chancellor allocates funding across the UK government departments in his budget later this month, and particularly the extent to which English spending departments will be compensated for higher inflation via budget top ups \u2013 if this happens at all.<\/p>\n<p>In retrospect, this agreement may be seen as the easy part; next year\u2019s annual budget will show whether this first deal was a genuine foundation for cooperation or whether it merely postponed hard choices until winter.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"Ed Gareth Poole and Owain Cynfab Wales Fiscal Analysis, Cardiff University\u2019s Wales Governance Centre On Tuesday 13 October, the Welsh Government and Welsh Labour reached an agreement on a Second [&hellip;]","protected":false},"author":7184,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_jetpack_newsletter_access":"","_jetpack_dont_email_post_to_subs":false,"_jetpack_newsletter_tier_id":0,"_jetpack_memberships_contains_paywalled_content":false,"_jetpack_feature_clip_id":0,"_jetpack_memberships_contains_paid_content":false,"footnotes":"","jetpack_publicize_message":"","jetpack_publicize_feature_enabled":true,"jetpack_social_post_already_shared":true,"jetpack_social_options":{"image_generator_settings":{"template":"highway","default_image_id":0,"font":"","enabled":false},"version":2},"jetpack_post_was_ever_published":false},"categories":[60],"tags":[],"class_list":["post-2322","post","type-post","status-publish","format-standard","hentry","category-finance"],"jetpack_publicize_connections":[],"jetpack_sharing_enabled":true,"jetpack_shortlink":"https:\/\/wp.me\/p8iFWs-Bs","meta_box":[],"jetpack_featured_media_url":"","_links":{"self":[{"href":"https:\/\/blogs.cardiff.ac.uk\/thinking-wales\/wp-json\/wp\/v2\/posts\/2322","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/blogs.cardiff.ac.uk\/thinking-wales\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/blogs.cardiff.ac.uk\/thinking-wales\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/blogs.cardiff.ac.uk\/thinking-wales\/wp-json\/wp\/v2\/users\/7184"}],"replies":[{"embeddable":true,"href":"https:\/\/blogs.cardiff.ac.uk\/thinking-wales\/wp-json\/wp\/v2\/comments?post=2322"}],"version-history":[{"count":4,"href":"https:\/\/blogs.cardiff.ac.uk\/thinking-wales\/wp-json\/wp\/v2\/posts\/2322\/revisions"}],"predecessor-version":[{"id":2327,"href":"https:\/\/blogs.cardiff.ac.uk\/thinking-wales\/wp-json\/wp\/v2\/posts\/2322\/revisions\/2327"}],"wp:attachment":[{"href":"https:\/\/blogs.cardiff.ac.uk\/thinking-wales\/wp-json\/wp\/v2\/media?parent=2322"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/blogs.cardiff.ac.uk\/thinking-wales\/wp-json\/wp\/v2\/categories?post=2322"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/blogs.cardiff.ac.uk\/thinking-wales\/wp-json\/wp\/v2\/tags?post=2322"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
