Starting a Trade Business in the UK: The First-Year Checklist That Actually Matters

Quick answer

Going from employed (or subbing) to running your own trade business is mostly not a tools problem. You already have the skills and the van. It’s a sequencing problem: get the legal and insurance basics right in week one, the money habits right in month one, and the demand engine (brand, reviews, directories) building from day one, because the pipeline you’ll need in month six is planted now. Here’s the order that matters.

Week one: the legal spine

• Structure: most start as a sole trader (register for Self Assessment with HMRC) for simplicity; a limited company adds admin but caps personal liability and can be tax-efficient as profits grow. You can start sole and incorporate later; many do at the £30 to 50k profit mark. Get an accountant’s hour before deciding; it costs less than getting it wrong.
• Construction? Understand CIS. If you’ll subcontract for contractors, the Construction Industry Scheme means 20% deductions at source (30% unregistered). Register, and price knowing the cash-flow effect.
• Insurance before the first job: public liability (£1 to 5m, typically £60 to £300/year for a sole trader) is non-negotiable; add employers’ liability the day you take anyone on (it’s a legal requirement), plus tools cover and van insurance rated for business use.
• Certifications current and in your name: Gas Safe, NICEIC/NAPIT, FGAS or whatever your trade requires; schemes registered to a former employer don’t transfer with you.

Month one: money habits that prevent year-one deaths

Day one onward: plant the demand engine

Your first-year work will come from ex-colleagues, word of mouth and whoever finds you online. All three compound if you set them up early:

1. Name and brand done properly once: a name that passes the availability checks (the naming gauntlet), a professional logo with van-and-workwear files (what that costs), and a sign-written van, the single best local advert a trade owns.
2. Google Business Profile from week one: service-area setup, real categories, photos of every decent job (the setup guide). Reviews start at zero for everyone; the automated ask after every job is how you’re at 30 by Christmas.
3. A simple website that converts: one good page beats none for a year. Offer, photos, reviews, phone. The trade-offs are in one-page vs multi-page.
4. Directories deliberately: pick one or two (Checkatrade-class) and feed them properly rather than scattering thin profiles everywhere.
5. Tell the trade: ex-employers and fellow trades are year-one gold; plasterers recommend electricians, builders recommend plumbers. Print cards, hand them to every adjacent trade you meet.

The traps that end year one

Pricing like an employee (see above; it’s the big one). Taking every job, including the underpriced nightmares an hour away, out of fear: a diary full of bad work blocks the good work. No cash buffer. Aim for a month’s expenses before quitting the payroll, three months’ as the year-one goal. Invisible admin debt, the quotes not followed up and invoices not chased that quietly cost more than any tool. And looking improvised: the whole first-year game is looking like a real business before you feel like one, which is precisely what the brand, the van, the reviews and the paperwork system buy you; the full version of that argument is in branding for trades businesses.

What year one actually costs to set up

The startup conversation usually skips straight to the van and the tools. Here is the rest of it: the recurring and one-off costs a new UK trade business meets in the first twelve months, excluding vehicle and tooling.

Call it £2,000 to £5,000 before a single job, most of it unavoidable, and note how much sits in the recurring column; that is the number to divide across your billable days when setting a rate. Two economies are worth taking: order workwear in small quantities until you know what actually survives your trade, and skip the directory in month one, because a profile with no reviews converts poorly and the money is better spent on getting the first twenty reviews elsewhere.

The VAT decision most new trades get wrong twice

Registering before you have to is a real option, and it cuts both ways. If your customers are mainly homeowners, VAT registration effectively raises your prices by 20% overnight with nothing to show for it, a genuine competitive disadvantage against unregistered rivals. If your customers are mainly VAT-registered businesses or main contractors, they reclaim it, and registering lets you reclaim on the van, the tools and the materials. Watch the threshold approaching rather than discovering you crossed it: the trap is registering late and owing VAT on income you have already spent. Domestic reverse charge rules also apply to a lot of construction work between VAT-registered businesses, so ask an accountant which side of it your work falls on before you quote a big job.

The first ninety days, as a sequence

1. Days 1 to 7: structure registered, insurance live, business account open, accounting app connected, name and domain secured.
2. Days 8 to 21: logo and file set commissioned, van booked in for signage, workwear ordered, quote and invoice templates built with your details and terms on them.
3. Days 22 to 45: Google Business Profile verified with real photos; a single strong web page live; every ex-colleague, adjacent trade and merchant counter told you have started, in person.
4. Days 46 to 70: first jobs photographed properly; review request sent within 48 hours of each completion; card left with every customer and every neighbour who asks.
5. Days 71 to 90: review the numbers honestly (average job value, quote-to-win rate, unpaid invoices) and raise the rate on new quotes if you are winning more than about seven in ten.

That last figure is a useful early warning. A very high win rate on quotes almost always means underpricing rather than exceptional selling; a rate under about a third usually means you are quoting the wrong jobs, not quoting them badly.

Terms and conditions: the boring page that saves thousands

• Payment terms in writing: days, method, and what happens after. Late payment legislation entitles businesses to interest and a fixed recovery charge on commercial debts; saying so in your terms changes behaviour before you ever have to use it.
• Deposits and staged payments on anything with a material bill. Funding a customer’s materials out of your own cash is how profitable trades run out of money.
• Variations clause. “Anything not in the quote is quoted separately before it is done.” Scope creep on domestic jobs is a silent margin killer.
• Cancellation rights. Contracts agreed in a customer’s home usually carry a statutory cooling-off period, and there is a specific procedure for starting work inside it. Getting this wrong can make a bill unenforceable.

The identity decisions that are expensive to reverse

Almost everything in year one is reversible. Three things are not, cheaply. The name, once it is on a van, a scheme registration, a domain and a hundred customers’ phone contacts: run it through the availability and longevity checks before the vinyl goes on. The vehicle presentation, because redoing signage means paying twice and living with a half-branded fleet in between; the cost and method options are laid out in our vehicle and signage design guidance. And the file set behind your logo: a JPEG from a marketplace is fine until the embroiderer asks for vector and the signwriter asks for a one-colour version, at which point you are re-buying the logo you already bought. The kit that has to exist (polos, jackets, hi-vis and who wears what) is worked through in branded workwear and merch, and the surprisingly durable role of a decent card in a trade where numbers get handed over on site is in what business cards cost.

One forward-looking note: if commercial or contract work is anywhere in your plan, start collecting the evidence now: certificates, insurance schedules, method statements, photographed jobs, references. Procurement processes ask for a paper trail that takes a year to build and five minutes to lose, and the requirements are set out in winning commercial contracts as a trade business.
