Companies House · Glasgow

UK companies in Glasgow

The largest business hub in Scotland is Glasgow. It is strong in financial services, energy and engineering. The G postcode covers the city centre and the industrial belt around it. Scottish ltds file with Companies House in Edinburgh. English and Welsh firms file in Cardiff or London. Leadistry indexes both registers.

The most registered SIC codes in Glasgow

Counting active companies whose registered office is a Glasgow post town, these are the codes that come up most often on the August 2026 Companies House snapshot. Other letting and operating of own or leased real estate leads with 6,587 companies. It is worth reading against the sectors above: the authored view is what Glasgow is known for, this is what its companies actually filed.

A company may register up to four SIC codes and these counts include every position, so a business filed under two of them appears twice. Use the list to pick a code, then narrow by postcode and incorporation date. Every company you pull carries the Companies House record, the director's name, a verified website and a verified email, and the ones we cannot complete are not charged.

Answers

About Glasgow on Companies House

Are Scottish companies indexed alongside English ones?

Yes. Companies House runs one UK register. Scottish ltds get SC** company numbers. English and Welsh ltds get standard 8-digit numbers. Leadistry shows both, with nothing to set up.

What is the strongest Glasgow sector for B2B outreach?

Financial services in the G2 area, plus IT consultancy across the whole city. We find a named director email for a high share of firms in both. Every lead ships with a verified website and a verified email.

Can I filter by Scottish-registered companies specifically?

Filter by the company-number prefix SC. That leaves only Scottish-incorporated firms. It helps when you want firms under Scots law rather than English law.
