When

You don’t need to incorporate right away. As a rule, it’s smart to wait until you have strong validation for your business. This could mean consistent customer traction, confirmed product-market fit, or revenue. However, there are circumstances where you might need to incorporate early.

For example, if you have an investor ready to invest or you want to join an accelerator and need a business bank account, you’d need to register the company first. Similarly, if you’re looking to secure intellectual property (IP) or formalize agreements with co-founders, incorporating early can be helpful.

Outside of these situations, it’s often better to wait for solid validation before incorporating, as you might want to change things like the company name, address, or structure down the line.

Risks / Benefits

(I’m not a lawyer) Any work you undertake before incorporating would hold you personally accountable, whilst registering as a limited company shelters you from most personal risk.

There are other advantages too, such as tax optimisation. For example, instead of paying income tax like a sole trader, a limited company pays corporation tax, which can sometimes work out better depending on how much profit the business makes.

But incorporating also comes with risks. One is the ongoing admin—filing accounts, tax returns, etc. can add cost and time, even if you aren’t making much money at the start. It’s also a good idea to seek advice from a lawyer or accountant to make sure incorporation is the right move for you, as it locks in certain legal obligations.

The Process & Costs

At the time of writing registering a limited company online in the U.K costs £50, the process itself is quite straightforward. There are also a number of services that can handle this process on your behalf such as Tide, Ember & Rapid Formations among others pricing may differ and provide discounts to the government price (be sure to check specific details around ongoing costs with these providers).

Ongoing Obligations

After registering, you’ll have several legal commitments with Companies House. These will vary depending on whether you register for VAT or set up payroll, but some of the key obligations include:

• Confirmation Statement – A simple process that confirms your company’s details (like shareholders and contact information) with Companies House.

• Annual Accounts & Corporation Tax – You need to file accounts every year. It’s essential to use an accountant for this to avoid mistakes. Services like Ember can help make this process smoother and more affordable.

• VAT Returns & Payroll – If your company is VAT-registered or paying employees (including directors), you’ll need to handle these filings too. Speaking with an accountant is the best way to ensure everything is in order.

• Self-Assessment – As a company director, you may also need to file a personal self-assessment tax return, especially if you're taking dividends.

Filing accounts can be one of your biggest ongoing expenses (after staff), so it's crucial to find the right accountant—whether that's an online service or an accountant.

First thing you want to do is validate your idea in one way or another. In my view the best way is always to try and get payment early even if the product is not built (you can always refund people after) make a quick and simple page explaining the service and throw a buy button on it and get this in front of people

This may not apply to all ideas, not everything is something people can “buy” but think about what might be an alternative strong signal.

• Don’t worry about people “stealing” your idea

• Ideas are cheap (It’s all about execution)

• Development is “easy” – Distribution is key

At the same time try to avoid letting external opinion sway you too much in a overly positive or negative way – Startups are a rollercoaster it is important to keep as balanced as you can.
