Net zero economy now employs over a million UK workers

1,058,000 full-time equivalent jobs now depend on the UK’s net zero economy. That figure, published by the Energy & Climate Intelligence Unit (ECIU) on 14 October 2024, is not a projection or a target, it is a headcount of people already working in low-carbon industries. For the homeowner weighing up whether to install solar panels or replace a gas boiler with a heat pump, this number matters. It means the supply chain is real, the skills base is growing, and the transition is already embedded in the labour market.

As reported by the Energy & Climate Intelligence Unit, the net zero workforce now exceeds employment in sectors like finance and construction. The report, compiled with the consultancy CBI Economics, found that jobs in low-carbon electricity generation, energy efficiency, and electric vehicles have risen by 13% since 2020. Solar installation alone accounts for over 50,000 roles. This is not a niche industry anymore.

Who qualifies, and who doesn’t

The jobs are spread unevenly. Scotland and the North East have high concentrations in offshore wind. The South East and London lead on heat pump installation and building retrofit. But the critical point for the homeowner is this: the workforce is becoming more accessible. In 2020, finding a certified heat pump installer in some regions meant a six-week wait. Today, the Microgeneration Certification Scheme (MCS) lists over 1,800 heat pump installers, up from 1,200 in 2021. Solar panel installers have grown by a similar margin. The net zero economy is not abstract, it is the person who turns up at your door with a van and a toolkit.

The catch is that demand still outstrips supply. The ECIU report notes that the government’s own projections require 1.4 million net zero jobs by 2030. The gap of roughly 350,000 roles means competition for skilled labour is intense. Homeowners in rural areas or on islands may still face premium prices and longer lead times. The solution, as Energy Saving Trust points out, is to book early and compare quotes from at least three MCS-certified installers.

What it costs a typical 3-bed semi

The job numbers translate directly into household costs. A typical 3-bed semi in the South East installing an air-source heat pump under the Boiler Upgrade Scheme now pays between £7,000 and £13,000 after the £7,500 grant. Two years ago, the same job cost £10,000 to £16,000, partly because fewer installers meant higher prices. The expansion of the workforce is already driving down installation costs. Ofgem data shows the average heat pump quote has fallen by 12% in real terms since 2022.

Solar panels follow a similar trend. A 4 kW system now costs £5,000 to £8,000 installed, down from £6,000 to £10,000 in 2021. The payback period for a typical household using 3,500 kWh a year has dropped from 15 years to under 10, thanks to the Smart Export Guarantee and lower upfront prices. The ECIU report does not give cost figures, but the correlation is clear: more workers mean more competition, which means lower prices for the homeowner.

But what about the grid and planning?

Yet the report glosses over two bottlenecks. First, grid connection delays. National Grid ESO has warned that some solar and heat pump installations require grid upgrades that can take 18 months. Second, planning permission. In conservation areas and listed buildings, solar panels and heat pumps still face restrictive rules. The ECIU’s employment numbers assume these barriers will be resolved, but they are not yet. Homeowners should check local planning policies before budgeting for any upgrade.

What this misses is the regional variation. The report’s headline figure is national, but a homeowner in Cornwall will find a different market from one in Cumbria. Cornwall has twice as many solar installers per capita as the North West, partly due to higher sunlight hours and early adoption. The net zero economy is not uniform, it reflects local history, policy, and infrastructure.

What you can do now

Households considering an eco-home upgrade should act before the workforce gap tightens again. The Boiler Upgrade Scheme runs until 2028, but grants are capped at 50,000 per year. The Solar Together group-buying scheme is active in 40 local authorities. Book a home energy assessment through the Energy Saving Trust first, it costs around £100 and identifies the cheapest, highest-impact measures. Installers are available now, but the report suggests they will be busier next year. The window is open, but it will not stay that way forever.
