Ask most business owners why growth feels harder than it should, and pricing rarely comes up as the answer. Ask a few pointed questions about how the price was actually set, and it usually turns out to be the root of it.
A huge number of prices in small business get set once, early, based on a guess or on what felt comfortable to charge without getting laughed out of the room — and then never properly revisited. Costs go up. Skill goes up. The price stays put out of habit.
Cost-plus is a floor, not a strategy
Working out your costs and adding a margin tells you the least you can charge without losing money. It tells you nothing about what the work is actually worth to the person buying it. Two businesses can do near-identical work and justify very different prices, because the value isn't really about the hours — it's about the outcome for the client.
A plumber fixing a leak and a plumber fixing a leak an hour before a dinner party for twelve are, technically, doing the same job. The value to the customer is nowhere near the same, and pricing that ignores the difference leaves money on the table in one case and overcharges in the other. Cost-plus pricing can't see that distinction, because it was never built to.
The same logic applies outside the trades. An accountant filing a routine tax return in March and one rescuing a client from a missed 31 January Self Assessment deadline are doing similar technical work, but the second is worth far more to the client — the alternative is a penalty and real stress. Cost-plus would charge both the same, based on hours. Value-based pricing recognises one is solving a £100 problem and the other a £1,000 one.
If you've never had a client push back on price, that's not proof your pricing is fair. It might be proof it's too low.
Why owners underprice in the first place
It's rarely about the numbers. It's about the conversation. Most people find it more comfortable to quote a number that gets accepted instantly than one that might get questioned — even when the higher number is genuinely fair. That instinct is understandable and almost universal, and it's also quietly expensive, compounding across every quote, every year, for as long as it goes unexamined.
The businesses that get comfortable with pricing reframe the discomfort: a client pushing back on price isn't a sign something's gone wrong. It's a normal part of a normal commercial conversation, whether your price is £50 or £5,000. Expecting it, rather than being thrown by it, changes how the whole conversation goes.
One version of underpricing is worth naming separately: quoting low to 'get the relationship started', meaning to raise prices once trust is built. In practice this rarely happens on schedule — the client has anchored on the low number, and every month without a review makes the eventual increase feel bigger. If a discounted opening rate is genuinely necessary, agree the review date and new rate in writing before the first invoice goes out.
The re-pricing conversation nobody wants to have
Raising prices on existing clients feels uncomfortable, so most businesses avoid it and quietly eat the cost of inflation instead. A simpler approach: set a clear point in the year when prices review, tell clients in advance, and apply it consistently rather than making it personal or apologetic. Clients rarely leave over a well-communicated, reasonable increase. They leave over surprises.
The wording matters more than owners usually expect. 'Prices are increasing because costs have gone up' is a fact, delivered plainly, with no apology built in. Apologising for a fair price increase quietly signals that you don't think it's actually fair, and clients pick up on that far more than they pick up on the number itself.
Timing matters too. A month's genuine notice is reasonable for most small-business relationships, longer for annual contracts — it lets clients budget rather than feel ambushed. Put it in writing rather than mentioning it in passing on a call, and apply it to every client on the same basis. Negotiating case by case in the moment just means your most persistent client ends up paying the least, simply for pushing back hardest.
What actually happens when you raise prices properly
The fear is always the same: clients will leave. In practice, a well-communicated, reasonably sized increase loses very few clients — and the ones it does lose are disproportionately likely to be the ones who were least profitable to serve in the first place. A price rise that costs you 5% of your client base while raising revenue by 15% isn't a loss. It's a filter, and usually a healthy one.
Put rough numbers against it. A business with 40 clients paying £200 a month raises prices by 10%, to £220. Even if the 5% who leave is two clients, monthly revenue moves from £8,000 to £8,360 with 38 clients instead of 40 — more money, less delivery work. Those two were also very often the ones who called most, queried the invoice most, and took up time disproportionate to what they paid. Losing them is capacity freed up, not a cost to mourn.
The VAT and margin trap UK businesses walk into
There's a specifically UK wrinkle that catches growing businesses out: crossing the £90,000 VAT registration threshold. A business pricing purely on 'what the market will bear', without planning for registration, finds that the moment it crosses the threshold, 20% has to come from somewhere — a thinner margin, or a price rise landing on clients used to the old number. Building VAT into the pricing model well before you're close avoids a forced increase arriving alongside a forced registration, which reads to clients as one shock instead of two sensible decisions made in good time.
The other margin trap is quoting a price once and never checking it against rising direct costs — materials, subcontractors, software licences, fuel. A price with a healthy margin built in eighteen months ago can have quietly eroded to almost nothing today, purely through cost inflation the business never re-tested it against. Reviewing prices only when a client complains means the erosion stays invisible until it's already serious.
The practical fix
Go through your current price list and, for each item, ask honestly: was this set based on value, or was it set based on nerves? Anything in the second category is worth revisiting — not necessarily doubling overnight, but moving deliberately rather than leaving it to inertia.
A useful starting exercise: pick your three most-delivered products or services and write down, in plain terms, what outcome the customer actually gets from each — not the task you perform, but the result they walk away with. Price conversations get easier once you're anchored to that outcome instead of your own hours or costs.
This week, put an actual date on your next review — not 'sometime soon', a real date in the diary — and decide now what you'll say when a client asks why. 'Costs have gone up and we're keeping the service at the same standard' is enough. Reaching for a longer justification is usually a sign you haven't quite convinced yourself yet, which is worth fixing before the conversation, not during it.
Common questions
How much should I actually put my prices up by?
Enough to restore the margin you have lost, which is usually more than the round number you had in mind. Work it backwards rather than guessing: take one typical job, list what it genuinely costs you today in materials, subcontractors and labour hours, and compare that with what it cost when the price was set. If direct costs have risen 12% and you have not moved in two years, a 5% rise still leaves you worse off than you were. Then sense-check it from the client's side rather than your own nerves. A 10% rise on a £200 monthly fee is £20, which is less than most clients spend on things they think about far less.
How do I tell existing clients I'm raising prices?
In writing, with about a month's notice, stating the new price and the date it takes effect — and with no apology attached. A short email does it: prices are increasing from this date, your new rate is this, the service is unchanged, get in touch if you would like to discuss it. Do not bury it in a phone call or mention it in passing, because clients who feel ambushed leave over the handling rather than the number. Apply the same increase to everyone on the same date instead of negotiating case by case, or your most persistent client ends up paying the least purely for pushing hardest. Annual contracts deserve longer notice.
What if clients leave when I raise my prices?
Some will, and the arithmetic still favours you comfortably. Forty clients paying £200 a month is £8,000. Raise it to £220 and lose two of them, and 38 clients at £220 is £8,360 — more revenue from less delivery work. You would have to lose nine clients before you were worse off than before, which a reasonable, well-communicated increase very rarely does. The ones who do go also tend to be the least profitable to serve: the ones who query every invoice, call most often, and absorb time out of all proportion to what they pay. Losing them frees capacity you can sell to someone else. Plan for a little churn rather than being shocked by it.
How do I handle a customer who says I'm too expensive?
Ask what they are comparing you with, then decide whether you want the job at their number — do not discount reflexively in the room. Too expensive usually means one of three things: they have a cheaper quote, they cannot yet see what they are getting, or they genuinely cannot afford it. Only the first two are worth a conversation, and the answer to both is to restate the outcome rather than justify your hours. If you do need to move, change the scope rather than the rate: take something out, extend the timeline, cut the number of revisions. Dropping the price while keeping the work identical teaches every client that your first number was never the real one.
Do I need to build VAT into my prices before I register?
Yes, if you are anywhere near the £90,000 threshold, because registration stops being optional the moment you cross it. You must register once taxable turnover exceeds £90,000 in any rolling 12-month period, and you have 30 days from the end of the month you crossed in to notify HMRC. At that point 20% has to come from somewhere: either you add it and your prices jump, or you absorb it and your margin does. If your customers are VAT-registered businesses they reclaim it and barely notice. If they are consumers, they feel every penny. Model both well before you are close, so the price change is a decision you made rather than one imposed on you by a deadline.
