Most small business owners often put off raising their prices for longer than they should. The worry is understandable: a client leaves, the work dries up, and a price increase that was meant to help ends up costing you. In practice, the maths is usually kinder than the fear. This guide shows how to work out how many customers you could lose and still be better off, how to tell clients about the change, and what to do when someone pushes back.

Why holding your prices is rarely free

Your costs move whether or not your prices do. Inflation was 3.5% in the 12 months to September 2026, the National Living Wage rose to £12.71 an hour in April, and employer National Insurance, rent, software and suppliers costs, all tend to creep up. If your prices stay where they were, the difference comes out of your margin, and eventually out of your own pay.

Holding prices can feel like the safe choice because the cost is invisible. A lost client is easy to see. A margin that shrinks by a percentage point a year is not. The following signs usually mean it’s time to raise prices:

• You haven’t raised prices in 12 months or more, while your own costs have gone up.
• You’re fully booked, or turning work away, which suggests demand is higher than your capacity.
• Most quotes are accepted without discussion. A very high win rate often means you’re priced low.
• Your effective hourly rate has fallen because jobs take longer, or the scope of work has crept up.
• You can’t remember the last time a client questioned your price.

If you’re not sure what a sensible price is in the first place, start with our guide to pricing your services, and our piece on calculating what to charge.

Work out your numbers first

The fear of losing clients is easier to deal with once you put a number on it. If your costs per sale stay the same, a price rise means each remaining customer is worth more to you. So the question is how many customers would you need to lose, before you were worse off.

The calculation is: price rise divided by (gross margin plus price rise). Here is what it looks like for a few common combinations.

The lower your margin, the more a price rise helps. A business running on a 20% gross margin that raises prices by 10% only needs to hold on to two-thirds of its sales to make the same profit.

These figures assume your cost per sale stays the same, so they work best for businesses that sell products or fixed-scope services. If a lost customer also frees up your time or materials, you’re better off than the table suggests.

Deciding who to increase, and when

You don’t have to raise every price for every client on the same day. Splitting clients into groups usually works better.

On timing, the start of a new quarter, the new year or the new tax year all give you a natural reason. An increase tied to a calendar date feels like routine business, not a reaction to anything the client did.

Telling clients

How you tell clients matters more than the size of the increase. A few habits help:

• Give proper notice. Thirty days is the minimum most people consider fair, and for larger clients or bigger rises, 60 to 90 days is better.
• Put it in writing, and say it plainly. State the new price, the date it takes effect, and what it applies to. Don’t bury it in a longer message.
• Give a short, truthful reason. Rising costs is usually enough. Don’t over-explain or apologise, which signals that you expect an argument.
• Don’t ask for permission. “I’m updating my prices from 1 January” is a statement. “Would you mind if I raised my prices?” invites a no.
• Mention what’s staying the same. If the service, response times and the person doing the work aren’t changing, say so.

A short message is enough. For example:

If it’s been several years since your last increase, consider spreading the rise over two steps instead of one large jump. Two modest increases six months apart usually land better than a single 20% change.

Handling pushback

Some pushback is normal and doesn’t mean the client is leaving. A few responses work well.

• If they say it’s too expensive, ask what they’re comparing it to. Sometimes the answer reveals a misunderstanding about what’s included.
• If they ask for a discount, decide in advance whether you’ll offer one. A smaller rise or a longer notice period costs you less than dropping the price altogether.
• If they say they’ll look elsewhere, let them. A client who leaves over a modest increase may not have been a good fit at your old price either, and you’ll often find the work they were taking up gets replaced.
• If they leave and come back, which does happen, you’re in a stronger position when you reply.

One practical option is to offer a choice instead of a flat increase. A lower-cost version of the service with fewer features, or a longer commitment at a slightly reduced rate, gives price-sensitive clients a way to stay without you discounting your main offer.

Contract, legal and VAT points

Three other points are worth knowing:

• Consumer-facing prices have to be clear. If you sell to the public, the price you display should include any compulsory fees and taxes, with no extra charges added later in the process. The CMA’s guidance on price transparency sets out the rules.
• Variation terms in consumer contracts can be challenged as unfair if they let you change the price without a valid reason or without the customer being able to cancel.
• A price rise can push you towards the VAT threshold. If your taxable turnover is close to £90,000, higher prices bring registration forward. Read our VAT registration guide before you finalise the increase.
