Presidential foreign trips load costs onto taxpayers in the host country (policing, crowd control) and at home (airlift, protection). In 2018, Donald Trump’s working visit triggered ~£18m in UK policing and nearly 10,000 officers, the largest mobilisation since the 2011 riots. In 2019, the Met alone spent £3.42m over three days in London.

For 2025, we built three estimates using two public anchors. Air Force One costs $177,843 per flight hour (FY2021), and the UK’s G7 in Cornwall cost £52.7m to police. Those anchors point to a £8m–£35m range for UK policing and $3.8m–$5.4m for US flight costs, depending on the schedule and protest size.

What this means: a simple London visit lands near the low end. Add Scotland and big protests, and the bill jumps.

This article compares past visit costs with expected 2025 figures, showing where the money goes, who pays, and what else that money could buy.

TL;DR

• In 2018, UK police spent about £18 million and deployed around 10,000 officers. That’s the biggest UK policing operation since 2011.
• In 2019, the Met Police in London spent £3.42 million over three days and used 6,300+ officers. That’s the London slice only.
• Air Force One costs $177,843 per hour (FY2021). A single DC–London leg (~7 hours) is about $1.24 million.
• G7 Cornwall 2021 cost £52.7 million to police. Multilateral events cost more than a single leader’s visit.
• 2025 forecast: £8m–£35m for UK policing + $3.8m–$5.4m in US aviation → $14m–$50m total. The higher end assumes Scotland and large protests.
• Scotland golf stop (2018): £3.02m (Police Scotland). Treasury also pledged up to £5m support for extraordinary policing.

2025 UK Visit: Cost Scenarios (host policing + US aviation)

(Assumes Washington–London–Washington Air Force One (AF1) round trip; 2–3 C-17 support lifts; protest size scales UK policing.)

Benchmarks: AF1 $177,843/hr (FY2021); C-17 historical $23k–$24k/hr (training cost reference; mission costs likely higher in 2025); G7 Cornwall £52.7m policing.

So what? A Scotland detour or large demonstrations can push a “Base” visit into the High band by £10m+.

Related: Our breakdown of the cost to stage a Trump military parade, another security-heavy event where policing, staging, and overtime dominate the bill.

Two things push the total: UK policing and US aviation. The chart below shows how much each matters.

Assumptions: AF1 DC–London–DC; 2–3 C-17 cargo flights; protest size scales UK policing; no Scotland leg in “Low.”

What makes a 2025 visit expensive? Mostly police. Aviation is material but smaller; protests/extra legs drive the jump.

Headline Cost: President Trump’s UK Visits

• 2018 working visit (London/Windsor + Scotland stop): UK policing ~£18m with ~10,000 officers, the biggest UK policing op since 2011. US costs included Air Force One and support aircraft plus Secret Service, but detailed US line-items aren’t published.
• 2019 state visit (Palace events + D-Day commemorations): Met Police (Metropolitan Police) reported £3.42m over three days (6,300+ officers). Other forces also assisted, but a consolidated national total wasn’t released.

Per-day price tag (comparables):

• 2018 working visit (4 days): ~£4.5m/day in UK policing alone.
• 2019 state visit (3 days, Met only): ~£1.14m/day in London policing. (London subset.)

AF1 in bite-sizes: at $177,843/hr, that’s ~$2,964 per minute and ~$318 per airborne mile (assuming ~560 mph cruise). Using the older $206,337/hr figure yields ~$3,517/min and ~$377/mile.

AF1 costs about $2,964 a minute.

Factors That Drive Costs Higher

Trump’s trips had several unique cost drivers. The UK in 2018 was dealing with heightened terrorism concerns, leading to more stringent protective measures. Mass protests, including the giant Trump blimp in London, meant more policing hours and extended street closures.

Another factor was Trump’s large entourage. Beyond staff and advisors, his family members often accompanied him, requiring additional transport, accommodation, and security. The Scotland golf detour at Turnberry added extra police overtime and flight segments, multiplying the bill. A single side trip could cost $1–$2 million in added logistics.

How costs snowball: UK policing bills scale with footprint and protest size, Cornwall’s G7 hit £52.7m with ~5,000 mutual-aid officers; London-only state visits tend to sit far lower. That’s why a Scotland leg or mass demonstrations can swing costs by £10m+.

Family & Entourage Costs (Documented Impacts)

The US Secret Service’s travel and lodging costs rise when adult family members accompany trips. A GAO audit found $396,000 in Federal costs tied to three 2017 international trips by two of the President’s adult children (Uruguay, Dominican Republic, UAE). That’s separate from the President’s own travel bill.

There’s also a venue effect: watchdog records show the Secret Service spent nearly $2 million at Trump-branded properties during the presidency, including room blocks and workspace that protection details needed while safeguarding him and his family. On UK trips, add this to the usual hotel blocks for staff and media.

Reporter takeaway: when more family join an overseas visit, expect extra hotel rooms + extra days on the road for Secret Service teams + additional motorcade elements, which can nudge a bilateral visit’s non-airlift costs from the low six figures toward the mid-six figures, before you count any golf-leg.

Golf-Leg Cost Multiplier (Scotland)

Why a golf stop matters: it adds new venues, routes, and police deployments to an already complex visit.

2018 Scotland leg (Turnberry):
• Police Scotland cost: £3.02m (FOI).
• Deployment: 5,500+ personnel claimed overtime/time off; protests at Turnberry and Edinburgh; extra perimeter/security infrastructure.
• Treasury support: UK Government pledged up to £5m to cover extraordinary policing if the Scotland golf stop went ahead.

2025 projection: If a Scotland detour is added (Prestwick/Turnberry), anticipate +£3m to £7m on top of a London/Windsor schedule depending on protest turnout and mutual-aid requirement, moving a Base scenario toward the High band in our table.

Where the Money Goes

In short: most of the money goes to planes and police; everything else is smaller.

Aviation Costs (documented unit rates → 2025 estimate)

How to read this: these are documented hourly rates multiplied by a typical UK trip profile.

Accommodation & Logistics

Big protests can add £10m+.

How It Compares (Presidents & Other Leaders)

Documented comparisons: GAO listed four Mar-a-Lago weekends in 2017 at ~$13.6m total (DOD + DHS), or ~$3.4m per weekend, and that’s domestic. International trips layer C-17 lifts and foreign policing. UK-side, 2018 policing was ~£18m and 2019 (Met only) £3.42m. Multilateral UK hosting (e.g., G7) reached £52.7m for policing.

Takeaway: Trump’s UK visits are on the upper end of bilateral visit costs primarily due to protest-driven policing and multi-site routing (e.g., Scotland). Avoid the apples-to-oranges totalising across presidencies unless methods match.

(Met Police London cost via FOI responses summarised by UK press; London share £3.42m and 6,300+ officers.)

Going further back, George W. Bush’s visits pre-2009 were cheaper in dollar terms, but after 9/11, security upgrades pushed costs upward by 15–20 percent. The general pattern shows that Trump’s trips were outliers, both in scale of policing and host burden.

Trump made 19 foreign trips during his presidency. Even conservatively averaging $25m each, the cumulative cost was ~$475m, approaching half a billion dollars. Obama (52 foreign trips) would be higher in total, but Trump’s per-trip costs were among the steepest due to entourage size and protest security.

The cost contrast with other world leaders is striking. A UK Prime Minister’s foreign trip often comes in under $1 million, even when traveling with a sizable delegation. French presidential visits range from €1 million to €3 million, while German chancellors often spend in the same band.

U.S. presidential trips are materially costlier than European leaders’ due to unique airlift and security layers.

Policing scale

Policing bills vary wildly: 2018 working visit £18m vs G7 2021 at £52.7m; 2019 is London-only.

Table: Cost Comparison of Diplomatic Visits

Who Pays?

• UK side: Under Foreign, Commonwealth & Development Office (FCDO) rules, the UK funds accommodation, transport, food and incidentals (to a set limit) for the principal + up to 10 officials during the official schedule, not flights; policing is borne domestically and can be reimbursed via Home Office special grants.
• US side: USAF covers presidential airlift (VC-25A/C-17), and the Secret Service funds protection; trip-level US totals are rarely itemised publicly. Use unit costs to scale scenarios.

Also on public-sector costs: our estimate for rebranding the Pentagon as the “Department of War”, from signage and seals to stationery and IT refresh.

What Else That Money Buys (Illustrative)

• £18m (UK 2018 policing) ≈ 410–470 NHS nurses for a year (assuming £38k–£44k average).
• One hour of Air Force One ($177,843–$211k) ≈ the typical home value in West Virginia/Mississippi (Zillow $170k–$190k), or ~70–85% of a typical Ohio home (Zillow $240k–$276k).
• 2019 Met Police £3.42m ≈ 65–70 teachers for a year in England (median pay £49k–£52k in 2024/25).
• Cost per UK household: With 28.6 million UK households (2024), £18m (2018 policing) equates to ~63p per household; £25m ≈ ~87p; £35m ≈ ~£1.22. (Illustrative; funding flows via central grants.)

Cost vs. Value Debate

Supporters argue the costs are justified. Diplomacy, NATO coordination, and trade negotiations require the presence of the U.S. president. Critics counter that the optics of golf detours and lavish entourages undermine the value. For another high-profile symbolic price tag, see our analysis of what it would cost to paint the U.S.–Mexico border wall black.

Opportunity costs are also clear. For the same $30 million, governments could build new schools, invest in rural healthcare, or upgrade critical infrastructure. Public perception, especially during Trump’s visits, leaned toward seeing them as costly spectacles rather than productive diplomacy, inflating the controversy around each trip.

Carbon Footprint of a Presidential Visit

Carbon footprint (order-of-magnitude): A DC–London round trip on a 747-class aircraft can emit ~300–450 tCO₂e depending on load and routing; adding 2–3 C-17 support sorties could contribute ~150–300 tCO₂e more, plus helicopter ops, so a ~500–900 tCO₂e trip is plausible. (Method: standard long-haul emission factors applied to VC-25A/C-17 class aircraft; true presidential loads are classified, so this is an indicative range.) (No official CO₂ ledger is published.)

Answers to Common Questions

How much does Air Force One cost per hour?

Air Force One costs $177,843 per hour (FY2021). A 2015 figure was $206,337.

Do host countries always pay for security?

Yes, host nations generally cover policing, protests, and local security. The U.S. pays for its Secret Service and air transport.

What was Trump’s most expensive foreign trip?

Estimates suggest the 2018 UK visit, with costs reaching $30M+, was among the highest due to mass protests and added golf detours.

Could video conferences replace some visits?

Yes, virtual engagements cost as little as $50K–$250K, but they lack the symbolic and diplomatic impact of in-person state visits.

How have presidential trip costs changed over time?

Costs have risen by about 50–60 percent since 2015, driven by inflation, heightened security, and expanded delegations.

Methodology & caveats (read me):

• AF1 $177,843/hr is FY2021 USAF cost per flying hour; newer reimbursable tables don’t list VC-25A publicly.
• C-17 $23k–$24k/hr is a 2014 training reference; operational/mobility missions in 2025 are likely higher; our totals show ranges.
• UK policing: consolidated 2018 national total £18m; 2019 £3.42m is Met-only. UK forces can claim Home Office special grants.
• Where precise line-items aren’t public, we present documented unit costs × transparent assumptions (legs, hours, convoy size).
