What this means if you’re starting one
You can start without much equipment
The typical marketing or advertising agency company in Birmingham carries £2,550 of equipment and other fixed assets after depreciation, lower than 94% of UK industries.
Most of the cost of entry is time and running costs rather than kit, so a small test is cheap.
Most of these businesses are run by one or two people
The typical marketing or advertising agency company in Birmingham reports 1 employee; the top quarter has 2 or more (345 filings).
You are mostly up against owner-operators. Your own hours are likely to be your biggest cost, and the easiest one to undercount.
Most of your competition will be other newcomers
34% of the 767 marketing or advertising agency companies in Birmingham were formed in 2025–26, against 25% of all companies in Birmingham. Nationally, that share of new companies is higher than 92% of UK industries.
New rivals are arriving faster than in most trades, so your customers already have fresh options. Being new is not a difference on its own.

Check my ideaWhat these figures can’t tell you
Companies are counted where their registered office is, which may be an accountant or a home address rather than a shop. Sole traders and partnerships are not on the register, and electronically filed accounts cover roughly 60–75% of accounts filed each year. The figures describe companies that exist; they cannot prove demand for your idea or predict whether it will work. How the figures are built.
