Building, roofing and solar across Liverpool and Merseyside
One contractor for construction, roofing, renewable energy and fit-out across the Liverpool City Region, based around 35 miles away in Preston.
Cornerstone Group works for businesses, landlords and estates teams across the Liverpool City Region: Liverpool, Sefton, Knowsley, St Helens, Wirral and Halton. From our base at Walton Summit, beside the M6, our own site teams reach most of Merseyside in under an hour by the M6 and M58.
We bring construction and civil engineering, roofing and cladding, renewable energy and fit-out together under one contract, with one team and one point of accountability.
Our fit-out business has refurbished fast serve restaurants in Aintree and Southport, working around trading hours. The same group re-roofs warehouses, installs commercial solar PV and builds extensions for industrial and wholesale clients.
What we deliver across Merseyside
Roofing for docks, estates and trade parks
From Speke and Knowsley to Bootle, Aintree and the Wirral, many industrial and trade buildings carry ageing metal or asbestos cement roofs. We survey, repair, over-clad or fully replace them. See commercial roofing in Liverpool.
Solar for Merseyside businesses
Warehouses, factories and wholesale units with big roofs and daytime demand are ideal for solar. We design, install and maintain systems in-house and handle the grid application to SP Energy Networks. See commercial solar in Liverpool.
One accountable team
We keep design, groundworks, structure, roof, power and interior in one programme with one site lead. Fewer hand-offs means a clearer programme and nobody passing the buck.

Liverpool and Merseyside questions answered.
Can't see your question here? Our team is happy to talk it through.
Which parts of Merseyside do you cover?
All of the Liverpool City Region: Liverpool, Sefton, Knowsley, St Helens, Wirral and Halton. We also work across West Lancashire, Cheshire and the wider North West.
Are you a Liverpool company?
We are based in Preston, Lancashire, beside the M6. Most Merseyside sites are under an hour away, so we survey, manage and attend with our own people.
Can you work around a trading business?
Yes. Our restaurant refurbishments in Aintree and Southport were phased around trading hours, with dust and noise controlled so customers could keep being served.
Which electricity network covers Merseyside?
SP Energy Networks operates the local network across Merseyside and Cheshire. For solar, battery storage and EV charging we prepare and submit the connection application for you.
Can one contract cover the roof and the solar?
Yes. When we fit the roof and install the solar, both are covered by a single combined 30-year warranty, and one team runs the whole programme.
