UK’s Low Investment: How Our Voting System (FPTP) Affects Government Investment.

Here’s the part of the conversation that almost never gets discussed:

The UK’s persistent underinvestment isn’t just an economic choice — it’s baked into how our democracy works.

Britain uses First-Past-the-Post (FPTP), a system that rewards

• short-term political tactics,
• swing-seat bribery,
• headline-friendly tax cuts,
• and “announceables”…

These do not encourage long-term national investment. And when you look at our investment behaviour through that lens, the patterns suddenly make a lot more sense.

Let’s break it down.

1. FPTP Encourages Short-Termism — Because Governments Must Win Every 5 Years

Under FPTP, a party can lose millions of votes nationally but still win a majority in Parliament if they capture the right marginal seats.

This creates a perverse incentive:

• Spend money on immediate voter-pleasers such as freezes, rebates, temporary tax cuts.
• Avoid long-term investments (rail, energy, R&D, education) that take 10–20 years to bear fruit.
• Push capital spending into the “later” column—because later is after the next election.

Infrastructure doesn’t win marginal seats. Bills and taxes do.

As a result:

FPTP produces governments that think in electoral cycles, not national timelines.

Countries with proportional systems (Germany, Denmark, Sweden, Netherlands, New Zealand) consistently invest more because their political structures reward long-term planning.

2. FPTP Creates Wild Policy Swings — Which Scare Off Private Investment

Business investment in the UK is the lowest in the G7.
Why? A huge part of it is uncertainty.

Under FPTP:

• One election can flip the entire economic model.
• Industrial strategy is rewritten every 4–5 years.
• Regulations, tax incentives, R&D rules, trade priorities — all vulnerable to being scrapped overnight.

This is not normal in PR countries, where:

• Coalitions force compromise.
• Policy shifts happen gradually.
• Businesses can plan 10–20 years out because governments do too.

If you’re a CEO deciding whether to build a factory or data centre in the UK, you have to ask:

“Will this policy still exist after the next election?”

Increasingly, the answer is… “probably not.”

The result?
British firms sit on cash piles instead of investing, and overseas investors look elsewhere.

3. FPTP Produces Regional Neglect — and Underinvestment Follows Geography

Because elections under FPTP are won in a few dozen swing seats, investment naturally gravitates toward:

• commuter belts
• swing constituencies
• politically competitive regions

Meanwhile, huge areas of the UK become “safe seat deserts”:

• The North East
• Wales
• Scotland outside the Central Belt
• South West England
• Parts of Yorkshire and Lancashire
• Inner cities

These areas don’t decide elections, so both major parties underinvest in them.

Decade after decade, this contributes to:

• widening regional productivity gaps
• poorer transport links
• weaker skills investment
• persistent low business investment
• the “left-behind” phenomenon

PR countries don’t experience this geographic distortion because every vote counts equally, so investment is more evenly spread.

4. FPTP Blocks Consensus on Long-Term National Investment Strategies

Most successful high-investment countries rely on cross-party consensus:

• Germany: long-term industrial strategy
• Netherlands: long-term pension + infrastructure model
• Sweden: national innovation planning
• Norway: sovereign wealth strategy
• Denmark: energy strategy agreed across parties

The UK, in contrast, has a habit of:

1. Announcing a long-term national strategy
2. Cancelling it when another party wins
3. Relaunching a similar strategy under a new name
4. Repeating forever

This is how we end up with:

• HS2 (part built, part cancelled)
• Green Homes Grant (launched, scrapped, reformulated)
• Industrial Strategy (launched in 2017, scrapped in 2021)
• Repeated NHS reorganisations
• Fractured energy policy
• Inconsistent R&D policy
• Constant tax policy churn

It’s difficult to invest when the country itself won’t.

5. FPTP Makes Public Investment Politically Risky

Underinvestment isn’t a bug — it’s a feature of FPTP:

• High investment means higher visible upfront spending.
• Higher visible spending risks attack ads.
• Risky policies don’t win marginal seats.

So parties default to:

• short-term tax cuts
• eye-catching gimmicks
• frozen fuel duties
• one-off bonuses
• cancelled investments (which look like “savings”)

Meanwhile, future generations inherit the bill.

The Big Picture:

Investment in the UK is low because our political system rewards politicians for not investing.

Until we fix the underlying democratic structure:

• public investment will continue to lag
• private investment will remain weak
• long-term projects will be abandoned mid-way
• regional inequality will deepen
• policy certainty will remain fragile
• growth will stay low

Better economic outcomes require better political incentives.

And better incentives require a voting system designed for long-term thinking.
