Five of the UK’s biggest construction projects

From critical infrastructure upgrades to record-breaking projects and the build of flagship headquarters, the UK construction industry continues to innovate and deliver despite wider market uncertainties. Here are five of the UK’s biggest ongoing construction projects.


1. Houses of Parliament restoration

Few buildings in the UK are as iconic as the Palace of Westminster but it’s in need of some urgent restoration. Work is currently at the surveying stage but it has been estimated the project could take up to 17 years if the most ambitious levels of improvements and renewal are given the go ahead. A final decision is expected in 2025.

2. Tata Gigafactory

In early 2024 the location of the UK’s biggest electric vehicle battery manufacturing facility was confirmed as a former munitions factory site near Bridgwater in Somerset. It’ll be one of the largest gigafactories in Europe capable of producing enough battery cells to supply around half a million passenger vehicles per year. The project, led by Tata Group’s global battery business, Agratas, is expected to go into the main construction phase in summer 2024.

3. Dogger Bank Wind Farm

Up to six million homes could be powered by Dogger Bank Wind Farm when it’s completed. The site – around 130km off the North East coast of England – will be the world’s largest offshore wind farm. As well as the engineering feat of installing turbines out at sea, extensive onshore works, such as underground cabling and construction of converter stations, are required. Electricity was first generated on the site in 2023 and it’s due for completion in 2026.

4. Google’s ‘groundscaper’

Google’s new London headquarters in King’s Cross is longer than the Shard is tall, hence its nickname as a ‘groundscaper’. Housing an impressive one million sq ft of office space, it features a rooftop exercise trail (complete with 250 trees), a 25m swimming pool and even a basketball court. Designed by Heatherwick Studio and constructed by Lendlease, the building’s set to welcome the first of its 4,000 staff by the end of 2024.

5. HS2 high-speed rail link

Due to run from Birmingham to London Euston, HS2 is currently at peak construction: employing over 28,000 people across 350 active sites. Despite the initial proposed network being scaled back, this vast project is delivering four new stations, 64 miles of dedicated high-speed tunnels, over 50 new viaducts and 44 miles of cuttings excavated. The actual trains, and the extra capacity and reduced journey times they bring, are expected to start running from around 2029.

Contract cleaning: what’s next in hygiene standards

Contract cleaning: what’s next in hygiene standards

Workplace hygiene standards have always been a priority for managers, but the Covid-19 pandemic brought these issues under unprecedented scrutiny. New expectations around cleanliness at work are combining with other pressures to make the next 12 months a year of transformational change for the contract cleaning and facilities management sectors.
