When politicians talk about defence budgets, most of the conversation focuses on fighter jets, submarines and new kit. But for those of us who wear the uniform, defence spending is more than a line in the Treasury’s accounts: it directly affects pay, housing, training and quality of life. In the latest 2025/26 budget, the UK plans to spend around £62.2 billion on defence, equivalent to about 2.4 % of GDP. The government aims to raise spending to 2.5 % of GDP by 2027 and 3.5 % by 2035. Where does this money go, and how does it trickle down to the everyday realities of service personnel? Let’s break it down.
Where the money goes
According to the latest budget analysis, almost half of the defence budget – roughly 49 % – goes towards equipment procurement and support. That’s the shiny stuff: ships, aircraft, vehicles and the maintenance and through‑life support that keeps them battle‑ready. The next largest slice, roughly 40–45 %, is for personnel and operations. This covers salaries, pensions, training, recruitment and the costs of deployments. A significant portion also funds the nuclear deterrent (about 18 %) and infrastructure such as bases and training areas.
What do these numbers mean? Nearly half of the MOD’s cash is being spent on people – our pay, training and welfare. When budgets rise, there is often more room to improve pay scales and conditions. When budgets are squeezed, pay stagnates and training cycles get cut back.
Pay and allowances
After years of pay restraint, the Armed Forces’ Pay Review Body recommended a 4.5 % pay increase from 1 April 2025. The review panel explicitly linked its recommendation to recruitment and retention challenges: the full‑time trained strength fell by about 3 600 personnel in 2024 and voluntary outflow remains high. A standard 3 % rise would not be enough to stem the exodus, so the review body concluded that a higher award was necessary. For junior ranks, this increase is also intended to keep pay above the National Living Wage.
Pay is not just a number on a pay slip. It’s a tangible signal that the nation values its armed forces. A competitive wage helps attract new recruits and encourages experienced troops to stay. Without it, frustration grows; we have all served with people who left because they felt undervalued. While a 4.5 % rise is welcome, inflation and housing costs mean many military families will still feel the squeeze.
Accommodation and welfare
One of the most visible – and often most overlooked – impacts of defence spending is the state of military accommodation. The 2025 budget allocated more than £1.5 billion in additional funding to repair and modernise Armed Forces housing and facilities. The budget also includes uplifts specifically to improve service personnel accommodation and welfare. This investment is badly needed. The Pay Review Body described some Service Family Accommodation (SFA) and Single Living Accommodation (SLA) as “disgraceful” and noted that poor accommodation undermines morale and retention. It urged the MOD to prioritise investment and bring all accommodation up to an acceptable standard.
Good accommodation is not a luxury – it’s part of the moral contract between the nation and its armed forces. Families need safe, warm homes; single personnel need clean, decent quarters. Investing in housing reduces stress, improves quality of life and signals respect for service.
Training and readiness
Training costs are embedded in the personnel and operations budget. When budgets shrink, units find themselves cutting back on courses or stretching training intervals. Higher spending supports more realistic training, updated simulators and enough ammunition for live firing. The budget increase also includes a new £400 million Defence Innovation Fund aimed at emerging technology such as drones, autonomous systems and advanced materials. While this fund is targeted at industry and research, its benefits will ultimately filter down to frontline units.
Recruitment and retention
Defence spending sets the conditions for recruitment and retention. Competitive pay, modern accommodation and proper kit all contribute to a sense that service is valued. Conversely, inadequate pay rises and crumbling barracks erode morale. The Pay Review Body noted that pay must remain broadly comparable with the private sector. With a strong civilian job market, particularly for those with technical skills, the armed forces must offer an attractive package. The 2025 budget’s focus on personnel welfare and housing is therefore more than window dressing – it is a strategic investment in maintaining a professional, capable force.
Broader economic impact
Defence spending does not only affect service personnel; it has ripple effects through the wider economy. Over £31.7 billion of defence spending flows directly to UK industries, supporting more than 200 000 jobs. As the budget increases, there will be more apprenticeships, graduate schemes and regional development tied to defence projects. For veterans transitioning into civilian life, a growing defence industrial base means more opportunities in shipbuilding, aerospace, cyber security and engineering.
The long view
Budget debates often turn into political point‑scoring, but at the coalface we feel the results in our pay packets, our accommodation and our training. The planned increase to 2.5 % of GDP by 2027 suggests that the government recognises the need to invest – but the quality of that investment will matter. Money allocated to nuclear deterrents and advanced kit is important for national security, but so is ensuring that troops have decent housing and that families are not living in sub‑standard quarters. A well‑funded military is not just about bigger ships or more jets; it is about the people who operate them.
Bottom line
Defence spending is not an abstract policy: it has a direct impact on the lives of service personnel. The 2025/26 budget increases will help improve pay, accommodation and training, but there is still work to do. As The FORCES Bible community, we will continue to hold policymakers to account and ensure that investment reaches the front line. Decent pay, safe housing and modern equipment are not luxuries – they are the basics of respecting those who serve. By understanding where the money goes and what it means for us, we can better advocate for the changes that matter.
