The Hemel Hempstead business picture
At the Companies House snapshot of 1 September 2026, the Hemel Hempstead post town had 8,061 active companies. In the 12 months to August 2026, 992 new companies were incorporated there, which is 123.1 for every 1,000 active companies against 137.5 for the UK. That ranks Hemel Hempstead 128th of 175 post towns with at least 5,000 companies for the rate of new incorporations, where 1st has the highest rate.
The post town has 114 accountancy firms registered as companies, which is 71 companies for every firm against 83 for the UK. Hemel Hempstead ranks 134th of the 175 towns, where 1st has the most companies per firm, so it is better supplied with incorporated practices than the UK average.
The HP postcode area covers far more than Hemel Hempstead, reaching Berkhamsted, Tring, Aylesbury, Amersham and High Wycombe. It holds 45,738 active companies, saw 5,373 new companies in the same 12 months (117.5 per 1,000) and has 723 accountancy firms, or 63 companies for each.
These are company figures, not business figures. Sole traders and ordinary partnerships are not on the Companies House register, which matters here: many electricians and other trades work as sole traders and will not appear. Registered addresses holding 1,000 or more companies, such as formation agents, are excluded, and a registered office is not always where a company trades.
For a Hemel Hempstead business, the practical choice is often structure before accountant: whether to stay a sole trader or incorporate, and what that changes for tax, the Construction Industry Scheme and VAT. An accountant who works with your trade can set out both routes on your real numbers.
Industries that stand out
A location quotient compares a place's share of companies in a trade with the UK share, so 1.5 means 1.5 times the UK share. These figures are for companies with a Hemel Hempstead registered office. Three trades clear 1.15 without a caveat. Employment placement agencies show a much higher figure, 3.51, but a figure this high can reflect a group registered locally with many subsidiary companies rather than many independent agencies, so we have not treated it as a local cluster.
Electrical installation (1.5)
There are 143 active electrical installation companies with a Hemel Hempstead registered office. Most electricians working for building contractors fall under the Construction Industry Scheme. A contractor deducts 20% from payments to a registered subcontractor and 30% if you are not registered, and the deductions count as advance payments towards your tax and National Insurance. You can apply for gross payment status to be paid without deductions. If you are VAT registered, most construction services reported under CIS use the VAT domestic reverse charge, unless your customer tells you in writing that it is an end user. More on accounting for electricians.
IT consultancy (1.32)
Hemel Hempstead has 288 active IT consultancy companies. For a contractor supplying their own services through a company, IR35 status depends on who the client is. A public sector body or a medium or large private company decides your status and should give you a status determination statement. A small private client leaves the decision with your own company, contract by contract. Our contractor accountants review IR35 on every contract.
Advertising agencies (1.24)
There are 83 active advertising agency companies in the town. Agencies regularly pay third parties such as media owners, printers and photographers, and then bill clients, so the VAT treatment of those costs matters. A cost is a disbursement outside the scope of VAT only if you paid it as your client's agent, it was the client's responsibility, you pass on the exact amount and show it separately on the invoice, among other conditions. Costs you incur to deliver your own service, such as your travel, are recharges and need VAT charged on them. See our page for marketing agencies.
