Heat pumps and insulation could cut UK living costs faster and more broadly than new North Sea oil drilling, according to research from the thinktank E3G. The study compares the government’s £15bn warm homes plan with projects such as the Rosebank oilfield, finding the insulation approach delivers larger savings for households and more jobs.
The warm homes plan would slash £1bn a year from household energy bills across the UK, with benefits concentrated on low-income households, E3G says. It would also add roughly £1.6bn annually to the economy and support about 50,000 new jobs across thousands of small businesses. By contrast, the Rosebank oilfield is expected to create only about 1,100 jobs, according to the thinktank.
Key Facts
- The UK government’s warm homes plan is budgeted at £15bn.
- It would cut household energy bills by £1bn a year, E3G says.
- It could create around 50,000 jobs spread across thousands of small businesses.
- It would deliver a £1.6bn yearly boost to the UK economy.
- The Rosebank oilfield would create about 1,100 jobs, the thinktank finds.
What the plan covers
The warm homes plan focuses on retrofitting existing housing stock with better insulation and replacing gas boilers with electric heat pumps. These measures reduce the amount of energy households need to heat their homes, which directly lowers energy bills. E3G says savings are expected to be largest for low-income households, who spend a greater share of their income on heating.
Beyond direct bill reductions, the programme is estimated to inject about £1.6bn per year into the economy. E3G attributes this boost partly to demand for labour and materials across thousands of small businesses involved in installation, manufacturing, and retrofitting. The thinktank estimates this activity would generate roughly 50,000 new jobs, spread widely rather than concentrated at a single site.
What happens next?
The government’s £15bn funding for the scheme is reportedly facing cuts as ministers look for budget savings, according to Business | The Guardian. If spending is reduced, the projected bill savings, job creation, and economic boost could fall short of E3G’s estimates. The thinktank’s comparison with the Rosebank oilfield suggests policymakers will weigh immediate fuel savings and broad employment against longer-term oil revenues and far fewer jobs.
Crucially, the Rosebank oilfield project is expected to create only about 1,100 jobs over its lifespan, E3G says, while the warm homes plan generates tens of thousands. The contrast highlights how the distribution of benefits differs: oil projects tend to concentrate work and revenue, whereas insulation and heat-pump rollout spread activity across many regions and firms.
What We Know — and What We Don’t
Verified by the source:
- The warm homes plan is valued at £15bn.
- It would reduce UK household energy bills by £1bn a year.
- It would add £1.6bn annually to the economy.
- It would create about 50,000 jobs across thousands of small businesses.
- The Rosebank oilfield would create about 1,100 jobs, per E3G.
Still unconfirmed:
- Whether the government will approve the full £15bn budget.
- The exact timeline for delivering insulation and heat-pump upgrades.
- Independent verification of E3G’s job and economic impact estimates.
- Detailed breakdown of regional distribution of the 50,000 jobs.
- Long-term oil revenue projections for the Rosebank field.
Why It Matters
With many UK households facing high energy bills and rising living costs, the choice between demand-side home upgrades and domestic oil production has become a central policy question. The research frames insulation and heat pumps as delivering faster, more widely shared savings and employment than new oil projects, which the government is still weighing as it seeks budget savings across departments including energy and [economy and markets](/category/economy-markets).
What To Watch
Upcoming Treasury decisions on winter fuel payments and the Spending Review will signal whether the £15bn warm homes plan survives intact, while a final investment decision on Rosebank is expected later this year.
