Revised 24 October 2026
E26 Overtime Tax Relief is not simply a tax reduction. It is an economic-capability measure designed to make additional productive work worthwhile, increase household earned income and enable British industry to make greater use of skills and productive capacity already in place.
Its purpose is wider than the immediate Exchequer calculation. Stronger productive capability expands the economic foundation from which wages, investment and sustainable public provision are ultimately supported. The fiscal test remains essential, but it is one measure of performance rather than the sole purpose of the policy.
E26 therefore reports the policy at two levels: first, the direct fiscal and economic account of overtime relief itself; second, its position within the wider E26 funding and economic programme. Assumptions, costs, additional output and fiscal recovery are shown separately so that neither account conceals the other.

1 Purpose and economic reasoning
Rewarding work and rebuilding productive capability
E26 proposes a practical opening measure for a wider renewal of British industry: make additional productive effort more worthwhile for employees and employers. Pride in work, mastery of a trade, enterprise and the opportunity to improve family circumstances are part of the policy’s purpose. The behavioural response is to be modelled and measured rather than assumed.
Wages, investment and sustainable public provision depend on the capacity to produce valuable goods and services. The policy seeks to strengthen that foundation by connecting additional earned income with additional production. Welfare and public services remain part of the economic system; their long-term funding requires a productive base that government must maintain and develop.
An employer may have customers, trained staff and suitable machinery, yet decline an additional order because overtime costs, financing or delivery constraints make it unattractive. E26 examines whether relief changes that decision enough to create worthwhile additional work in Britain.
Three connected beneficiaries
| Beneficiary | Intended gain |
| Employee | More take-home pay from qualifying overtime and more opportunities to earn through additional production. |
| Employer | More commercially viable orders, better use of installed equipment and, where employer NI is relieved, lower incremental payroll costs. |
| Nation | Additional UK value added, stronger industrial capability, export opportunities and a broader economic foundation for public provision. |
The gains are connected but must not be counted twice. Employee wages and employer profits can be components of value added. Additional exports, value added, company profit and government receipts are different measures, not amounts to add indiscriminately.
The proposition to test
Where genuine demand and usable capacity exist, reducing deductions on qualifying overtime may increase the willingness to supply and offer additional hours. Combined employee and employer relief may also make previously uneconomic orders viable. The test is whether this produces worthwhile additional capability after resource costs, displacement, delivery costs and public revenue effects are accounted for.
2 How the relief works
The core proposal
The proposed full version removes income tax, employee National Insurance and employer National Insurance on clearly recorded qualifying overtime. Employee-only relief is a separate comparison variant. These versions address different incentives and must have separate costings and results.
| Variant | Worker effect | Employer effect |
| Current baseline | Receives gross overtime less applicable deductions. | Pays gross overtime plus applicable employer contributions. |
| Employee relief | Retains qualifying overtime without the relieved income tax and employee NI. | Total cost of the same gross overtime is broadly unchanged. |
| Combined relief | Receives the employee benefit. | Also avoids employer NI on eligible overtime, lowering total incremental payroll outflow. |
The 42 pound example
| Input or result | Illustration |
| Normal hourly wage | £20 |
| Overtime premium | Time and a half |
| Qualifying overtime rate | £30 an hour |
| Hours in the example | 5 per week |
| Gross overtime wage | £150 per week |
| Assumed income tax and employee NI | 28 per cent combined |
| Take-home overtime without employee relief | £108 |
| Take-home overtime with employee relief | £150 |
| Additional take-home pay from relief | £42 per qualifying week |
The £42 is deductions avoided on the £150 wage, not the whole overtime wage. The 28 per cent is a modelling assumption, not a universal or verified current tax rate. Actual entitlement depends on the enacted scheme, earnings and personal tax circumstances. Employer NI savings would be calculated separately using the applicable rate and base.
At £42 per qualifying week, four weeks yield £168; 26 weeks yield £1,092; 46 weeks yield £1,932; and 52 weeks yield £2,184. The £182 average monthly figure assumes 52 qualifying weeks. With 46 qualifying weeks the calendar-month average is £161. Caps and working patterns can reduce these totals.
3 Workstations capacity and commercial decisions
Using capital already installed
The workstation argument is central to E26. A machine, production line, cutting table or assembly station has already absorbed expenditure on premises, installation, tooling and training. Additional productive hours can spread some fixed costs across more saleable output. The comparison is between realistic ways of fulfilling the next order, rather than overtime in isolation.
| Production option | Costs and constraints to compare |
| Use existing equipment for more hours | Overtime wages, NI treatment, materials, energy, supervision, maintenance, quality and available staff. |
| Install another workstation or line | Purchase or lease, financing, installation, premises, tooling, recruitment, training, commissioning and lead time. |
| Buy or manufacture overseas | Delivered cost, quality, freight, duties, inventory, financing, lead time, disruption and currency exposure. |
| Decline or defer the order | Lost contribution, customer relationships, delayed receipts and the risk of losing future business. |
Relief could change the employer’s decision even where it produces only a modest reduction in cost per unit. An order near its commercial threshold may become worthwhile; better delivery performance may also strengthen the case for subsequent contracts. These are hypotheses for the model to quantify.
Avoided and deferred expenditure
If overtime defers a workstation purchase, count the financing and timing benefit over the appraisal period, allowing for eventual expenditure and residual value. Do not count the full purchase cost as permanently saved where the equipment will still be needed. Conversely, a permanently avoided expansion should be compared against the output and capability that the alternative would have provided.
Higher utilisation is not automatically higher productivity per hour. The model will report output per machine, output per labour hour, unit cost and total additional value separately. Production must remain saleable and meet quality and safety requirements.
The worked factory assumptions
The earlier £50 value added and £15 profit per overtime hour remain parameters to test against actual orders and production accounts. The model must define whether profit already includes all incremental costs, and how value added is calculated, before these figures can be used together.
4 Cash flow and working capital
Why a profitable order can still be difficult to accept
A manufacturer may have to pay workers, buy inputs and fund production before receiving the customer’s payment. The peak cash deficit during that period can prevent an otherwise profitable order from being accepted. This makes cash flow a separate decision variable alongside margin and capacity.
Employee-only relief improves the worker’s cash position but does not directly reduce the employer’s cost of the same gross wage. Combined relief reduces the employer’s overall payroll outflow by the employer NI avoided. Record actual wage dates and HMRC payment dates so that the timing benefit is measured correctly.
The working capital comparison
| Measure | Before E26 and under each relief variant |
| Cash required per additional order | Incremental wages, employer contributions, materials and other payments before receipts. |
| Peak funding gap | Largest cumulative cash deficit after customer deposits and supplier credit. |
| Cash required per pound of additional output | Use an explicitly defined output valuation and the same method in every comparison. |
| Days until payment | Separate order, production, delivery, invoice and customer-payment dates. |
| Financing cost | Actual or scenario borrowing rate applied to the size and duration of the funding gap. |
Earlier completion can bring receipts forward if the contract allows earlier invoicing or payment. It does not do so automatically under fixed milestones or payment dates. Customer deposits and supplier credit may already reduce the financing gap.
Borrowing-cost savings should enter the economic account once. Do not count the same employer NI saving again as a separate working-capital benefit: the additional benefit is the financing or timing effect attributable to lower cash requirements.
5 The seven company pilot
A representative manufacturing selection
The proposed pilot comprises two large manufacturers, two medium manufacturers, two small specialist manufacturers and one fashion or textile manufacturer. It spans different production methods and commercial settings so that results can be compared across company sizes and sectors.
| Category | Proposed company | Application to assess |
| Large aerospace | Rolls-Royce | A defined UK component, machining or assembly operation serving international engine demand. |
| Large major exporter | JCB | UK equipment or component production; additional shifts compared with capital expansion and overseas allocation. |
| Medium precision components | Brandauer | Toolroom and press utilisation; additional export contracts and delivery performance. |
| Medium agricultural equipment | Alvan Blanch | Fabrication and assembly of drying and processing equipment for overseas customers. |
| Small advanced manufacturing | Coltraco Ultrasonics | Additional assembly, calibration and testing of exportable scientific instruments. |
| Small specialist manufacturing | William Whiteley and Sons | Skilled production and finishing of professional scissors and shears for overseas buyers. |
| Fashion and textiles | John Smedley | UK knitwear output, third-party manufacturing and the economics of returning production to Britain. |
These are proposed candidates, not participating or endorsing companies. The medium and small groupings are provisional: current headcount, group ownership and the scale of the selected UK operation must be confirmed. Available sources include historical employee counts and company-reported size bands, which are not audited current classifications.
Selection criteria
- A UK workforce and an identifiable UK manufacturing operation.
- Skilled or semi-skilled work with measurable hours, output and quality.
- Evidence of customer demand and the potential to add hours or shifts.
- Sufficient materials, equipment and downstream capacity to use additional labour.
- Domestic or export orders whose profitability, financing or delivery changes under E26.
- The ability to provide comparable payroll, production, cost and order data.
Existing international sales support candidate selection but do not establish spare factory capacity or an overtime bottleneck. The final choice of operation within each company follows verification of those conditions. Results should be reported per worker and per pound of relief as well as in total, giving small companies equal analytical attention.
Why John Smedley
John Smedley provides an established English manufacturing base at Lea Mills, Derbyshire. In 2024 it announced reopening production to third-party brands, with the stated aim of helping bring knitwear manufacture back to Britain. The accompanying industry report describes machinery investment, international distribution and a planned DAKS collaboration. Those historical developments make it a strong candidate for a model combining output expansion and reshoring. [1–2]
Current third-party orders, machine availability, staffing and programme status must be obtained directly before a live trial. Sunspel and Fashion-Enter remain reserve fashion candidates: the former has its own UK T-shirt factory, while the latter offers UK garment production and detailed production recording. [3–4]
6 Export growth and returning production to Britain
Export capability rather than sales alone
The export objective is sustained additional UK production that meets overseas demand competitively, reliably and profitably. Faster completion of an existing order can improve cash timing without increasing lifetime export sales. The model must distinguish earlier deliveries, genuinely new orders, repeat business and orders displaced from other UK suppliers.
Track incremental export revenue, UK value added embodied in those exports, imported inputs, delivery reliability, customer retention and margins. Export turnover is not equivalent to national value added or Treasury revenue.
The fashion reshoring comparison
| Option | Common comparison basis |
| Imported garment | Landed cost including manufacture, freight, duties where applicable, quality, returns, inventory and financing. |
| Current UK production | Equivalent specification, order volume, quality, lead time and realistic UK factory costs. |
| UK production with employee relief | Same basis with measured changes in labour availability, delivery and output. |
| UK production with combined relief | Also include reduced employer NI and attributable financing effects. |
The comparison will identify the price and delivery conditions under which a buyer would switch to UK production. Include any setup, sampling, tooling, certification or supplier-transition costs. A factory winning a new UK order from an overseas supplier is import substitution; selling additional UK-made garments abroad is export growth. Report both distinctly.
A wider UK cost advantage is not assumed. Raw materials, energy, skills, automation, quality, freight and trade arrangements may dominate the decision. The purpose of E26 modelling is to locate the orders and product lines where the incentive changes the commercial outcome.
7 Model development and verification
Stage one the desk model
Build a transparent model of order profitability, production capacity and cash timing, using explicitly labelled assumptions. Compare the no-policy baseline, employee-only relief and combined relief. Vary demand, willingness to work, machine availability, margins and financing to identify where the policy succeeds or fails.
Stage two complete verified operational data
Populate the model with actual wage bands, contractual hours, overtime premiums, payroll treatment, machine calendars, production rates, materials, defects, orders, delivery terms and cash flows. Reconcile production records with invoices and accounts. Flag missing or uncertain fields; incomplete data should not silently become a zero or a favourable assumption.
Model existing overtime, overtime induced by E26 and activity displaced from other hours, recruitment, suppliers or periods. The key question is what changes because of the policy compared with what would otherwise happen. This can be investigated with verified data before a live implementation has support or funding.
Stage three selected industry trials
Recruit suitable operations from the proposed seven-company mix. Compare predictions with observed outcomes and use comparable untreated operations or another credible evaluation design. Test employee and employer incentives distinctly where feasible. Agree the duration and sample from production cycles and the variability of outcomes, rather than assuming seven companies alone establish a national result.
Stage four export and reshoring development
Use the results to identify sectors and products with a durable opportunity for additional exports or import substitution. Wider deployment should retain the feedback process so that eligibility, cost and measured capability can be reviewed as conditions change.
Measures of performance
| Measure | Interpretation |
| Worker gain | Additional take-home pay, separately from gross overtime earned. |
| Production and capability | Additional saleable units, value added, utilisation, skills retained and delivery performance. |
| Employer outcome | Incremental profit, peak funding gap, financing cost and investment timing. |
| Fiscal outcome | Relief paid, additional receipts, administration and other incremental public costs. |
| Export and reshoring outcome | New overseas orders, UK value added in exports, and production switched from overseas. |
| Worker and market effects | Recruitment, displacement, fatigue, defects, injuries and unit prices. |
Additional value added per pound of gross relief and additional government receipts per pound of gross relief are useful separate indicators. A ratio above one is not alone proof of net national benefit, and fiscal recovery below one does not alone establish policy failure. Interpret the indicators alongside resource costs, distribution and benefits over time.
8 Fiscal account and wider E26 funding
The direct policy account
Net Exchequer effect equals incremental government receipts relative to the baseline, minus total qualifying relief, minus administration and other incremental public costs. A positive result indicates a fiscal improvement; a negative result is a net public cost. Show employee relief and employer relief separately.
Relief on overtime that would have happened anyway is included within total relief cost. Identify it as a component when assessing effectiveness, but do not subtract it a second time as deadweight. Treat displacement consistently in the counterfactual receipts and costs so the same effect is not counted twice.
The economic account separately measures incremental national benefits and resource costs, including investment timing, financing, production and displaced activity. The fiscal account is essential, but it is one performance measure within the policy’s wider purpose.
The wider E26 funding account
| Proposed replacement revenue or saving | Historical illustrative assumption |
| Civil Service replacement pause subject to service and AI review | £0.895bn gross ceiling |
| Government-to-government aid pause with project filtering | Up to £0.176bn |
| Digital reconciliation and hidden-economy recovery | £0.4bn–£0.9bn |
| Public Services turnover charge | £3bn target |
| Overseas Tax Base Charge | £4bn gross target |
| Combined assumptions | £8.471bn–£8.971bn |
| Less historical illustrative overtime relief cost | £7.912bn |
| Conditional arithmetic balance | £0.559bn–£1.059bn surplus |
These figures are inherited scenario assumptions, not current verified revenue forecasts. The balance requires the targets and savings to materialise without overlap and before omitted implementation costs. Revenue from genuinely additional overtime activity must be added only if it has not already been included elsewhere in the package.
The Public Services proposal used a 1 per cent charge on eligible turnover above £500,000 where corporation-tax liability is zero; its £3 billion target requires £300 billion of chargeable turnover. The overseas proposal used 2 per cent of eligible UK-customer receipts booked offshore; £4 billion requires £200 billion of eligible receipts. Tax bases, responses, collection costs and timing require independent costing.
The hidden-economy figure here is the £0.4–£0.9 billion recovery scenario, not the whole value of the black economy. Vacancy savings are conditional on maintaining services, and the aid measure is subject to project-level filtering. Both accounts must show gross and net amounts and when cash actually becomes available.
9 Eligibility safeguards and worker protection
Qualifying hours and verification
The development record proposes a declared contracted-hours baseline, with relief for hours above that baseline linked to actual demand. Digital timesheets, payroll and production records would support verification. A national 40-hour threshold is not assumed.
Earlier suggestions included a minimum overtime premium of 1.25 times normal pay, annual limits of 180–250 hours, a 12-month restriction on reducing contracted hours and additional checks for personal service company directors. These remain design options rather than settled policy. Rules need to accommodate variable and part-time hours without encouraging ordinary pay to be relabelled.
Cost control and anti avoidance
Potential controls include checking base-pay reductions, rejecting claims below a required premium and recovering relief on misclassified hours. The proposed shadow NI charge and automatic premium increases above a fiscal ceiling require legal and behavioural assessment before adoption. A higher premium can itself change employer costs and eligibility.
Work and worker protection
Overtime should be voluntary and compatible with applicable working-time and safety requirements. Monitor fatigue, defects, injuries and whether overtime displaces permanent recruitment. The work-ethic objective is to reward productive contribution; it does not imply that every worker can or should work additional hours.
Inflation as an observed outcome
Additional supply and lower unit costs could ease price pressure if they outweigh additional demand. The policy’s funding and timing also matter. Earned income and an unchanged gross wage do not prove that inflation cannot rise. Measure production costs, selling prices and relevant demand rather than promise an automatic price reduction.
10 Appendix on assumptions and development figures
Cost and entitlement assumptions
| Figure from the development record | Status or reconciliation |
| £7bn | Earlier working cost assumption, not an established Treasury forecast. |
| £7.912bn | Illustrative static cost quoted in the archive; underlying eligibility and payroll base need rebuilding. |
| £8bn | Copilot-proposed ceiling, not a validated estimate. |
| £3.864bn | 2m workers × 5 hours × 46 weeks × £30 × 28 per cent. Employee relief only; no employer NI or administration. |
| 180–250 hours | Unsettled cap. Five hours for 46 weeks is 230 hours; for 52 weeks it is 260. |
| £300–£480 monthly and related ranges | Earlier messaging mixed additional gross earnings with relief. Use the explicitly specified £42 example instead. |
| 13.8 per cent employer cost reduction | Historical claim not adopted. Employer NI rate and percentage reduction in total employment cost are different measures. |
The historical household illustration
The 29 September 2026 record lists a Tesco basket totalling £38.39, leaving £3.61 from the £42 weekly example. Its individual prices are historical, not current quotations. The basket is a purchasing-power illustration, not a complete household diet or evidence of the policy’s inflation effect.
| Recorded item | Price |
| Chicken breast fillets 1 kg | £6.69 |
| Lean beef mince 500 g | £5.05 |
| Free-range eggs 12 | £2.85 |
| Cheddar 400 g | £2.95 |
| Milk 4 pints | £1.65 |
| White bread 800 g | £0.75 |
| Baked beans 4 tins | £1.55 |
| Pasta 1 kg | £1.19 |
| Basmati rice 1 kg | £1.80 |
| Potatoes 2 kg | £1.32 |
| Carrots 1 kg | £0.69 |
| Broccoli 375 g | £0.90 |
| Bananas 5 | £0.78 |
| Gala apples 5 | £1.80 |
| Chopped tomatoes 2 tins | £0.94 |
| Frozen peas 1 kg | £1.70 |
| Cucumber | £0.99 |
| Red peppers 2 | £1.40 |
| Iceberg lettuce | £0.89 |
| Strawberries 400 g | £2.50 |
| Total | £38.39 |
| Left from £42 | £3.61 |
The source also compares £42 with a stated ONS 2023–24 weekly food and non-alcoholic drink figure of £70.50: about 60 per cent. A separate 52-week campaign illustration allocated £2,184 to uniforms £200, shoes £80, a holiday £1,100 and a buffer £804. These are communication examples, not universal benefits or verified current household budgets.
Inflation model and time bases
The source compared £84 million of weekly relief with £2.3 trillion annual GDP. A consistent 52-week comparison is £4.368 billion, about 0.190 per cent of that GDP assumption; at 46 weeks it is £3.864 billion, about 0.168 per cent. These ratios do not estimate inflation.
The earlier Trump Curve equation is retained below as a development model. Its coefficients and the mapping from overtime to programme share require validation before use as a policy forecast.
The record associates u with unemployment and s with programme share. Units, baseline and causal estimates must be defined. Avoiding an increase in unemployment is an objective rather than an outcome established by this equation.
