How to Handle 'Can You Just...' Requests Without Losing Money or the Customer

"Can you just move that socket while you're there?" "Can you just tile behind the toilet as well?" "Can you just add another downlight — it won't take long, will it?"

Every tradesperson knows this conversation. The customer is not being malicious. They are watching their house take shape and having ideas. The problem is that "can you just" almost never means five minutes. Moving a socket means chasing a wall, re-routing cable, making good, and redecorating. That is half a day — and if you absorb it, you have just worked for free.

The real issue is not the customer asking. It is the trade not having a process for answering.

Why extras spiral on residential jobs

On commercial sites, there is a formal variation process. Nothing changes without a variation order signed by the project manager. The system exists because everyone knows that uncontrolled changes destroy budgets and timelines.

On domestic jobs, there is usually no process at all. The customer asks for something. The builder says "yeah, no problem" because they want to keep the customer happy. Then another request comes. And another. By the end of the job, the builder has done two days of unpaid work and feels resentful. The customer has no idea anything is wrong because nobody told them there was a cost.

Every extra you absorb without charging for it trains the customer to expect the next one for free. The fifth request is not the problem — the first one you did not price was the problem.

The solution is not to say no to extras. Extras are often good business — they increase the value of the job and keep the customer happy. The solution is to have a clear, simple process for pricing and approving them before you start the work.

The three-step variation process

This does not need to be complicated. A variation process for domestic work has three steps:

1. Acknowledge the request

"Great idea — let me work out what that involves and get you a price."

This does two things. It tells the customer you are taking their request seriously. And it creates a pause before you commit to the work, giving you time to price it properly.

Do not give an off-the-cuff price. "Yeah, probably about fifty quid" said on site becomes "you said fifty quid" in a text message three weeks later, even if the actual cost is £200. Price it properly or do not price it at all.

2. Price and present

Work out what the extra involves — materials, labour, time — and give the customer a clear price. Put it in writing. A text message is the bare minimum. A proper variation through your contract app is better.

Include the impact on the timeline if relevant. "Adding the extra downlights will cost £180 and adds a day to the schedule" gives the customer a complete picture. They can make a decision based on facts, not assumptions.

3. Get written approval before starting

Do not start the extra until the customer has agreed to the price in writing. This is the step most tradespeople skip, and it is the one that causes disputes.

"But I don't want to be sending paperwork for every little thing." You do not need to. A text reply saying "yes, go ahead with the extra downlights at £180" is written approval. A signed variation in a contract app is better because it is tied to the original agreement, but even a text thread is a hundred times better than a nod on site that nobody remembers a month later.

The conversation that makes it easy

The reason most trades struggle with extras is the conversation. They do not want to seem difficult. They do not want the customer to think they are being nickelled and dimed. So they absorb the cost and hope it does not happen again. It always happens again.

Here is how to frame it so the customer feels good about the process:

"Absolutely, I can do that. Let me work out the cost and add it to the project so we both know where we stand."

That sentence does three things:

• It says yes — the customer's idea is not being rejected
• It signals that there is a cost — no surprises later
• It frames the process as protecting both sides — not just protecting your margin

Most customers respond positively to this. They are spending serious money on their home. They want to know what things cost. The customers who get angry when you try to charge for genuine extras are the customers who were always going to cause problems — and you are better off knowing that now than at the end of the job.

What happens when you don't charge for extras

Consider a real scenario. A plasterer is booked for a two-day skim in a living room and hallway. During the job, the homeowner asks if he can also skim the small downstairs toilet. "It's tiny, it won't take long." He says yes to keep them happy.

The toilet takes three hours including prep, and the plaster for it costs £15. He has just given away £150 of labour and materials. The customer does not know this. They think it was a five-minute favour.

Two days later, they ask if he can skim the landing as well. Now he is annoyed, but he already set the precedent. If he charges for the landing, the customer will ask why this one costs money when the toilet was free.

This is the trap. Once you absorb extras, the customer's expectation resets. Every subsequent request is measured against the free one, not against its actual cost.

Multiply this across a year. If you absorb two small extras per job, and you do forty jobs a year, that is eighty unpaid extras. At an average of £100-£200 each, you have given away £8,000 to £16,000 of labour. That is not generosity — it is a structural hole in your business.

How a contract stops this before it starts

A written contract with a clear scope and a variation clause prevents the entire problem. When the scope is written down — "skim living room and hallway walls, prep and two coats" — anything outside that is visibly extra. There is no ambiguity about what was agreed.

A variation clause says: "Any changes to the scope will be priced separately and require written agreement before work begins." That is one sentence in a contract, and it reframes every "can you just" conversation from an awkward confrontation into a normal business process.

The customer reads the contract before the job starts. They know the scope. They know that changes cost money. When they ask for the extra downlight, they already expect to pay for it — because the contract told them so.

Handling the persistent "can you just" customer

Some customers will keep asking regardless. They are not trying to cheat you — they are excited about their project and keep having ideas. The challenge is to stay professional without getting frustrated.

A few tactics that work:

• Batch the requests. "I'll keep a note of the extras you want and price them all together at the end of the week. That way you can see the total and decide which ones are worth doing."
• Reframe the conversation around value. "That's a great shout — the bifold doors would really open this space up. They'd add about £3,500 to the project but you'd get that back in property value."
• Refer to the contract. "Happy to do it — I just need to add it as a variation so we've got it recorded. I'll send it through the app and you can approve it from your phone."

The key is consistency. If you price variations every time, it becomes normal. If you only charge sometimes, the customer cannot predict when something will cost extra, and that is when frustration builds — on both sides. If you are dealing with a customer who keeps changing plans mid-renovation, our guide on handling mid-job changes covers the broader process.

The bottom line

"Can you just" is not the enemy. Extras are good business when they are priced and approved properly. The trade's job is not to say no — it is to make it easy to say yes at a fair price.

A written scope, a variation clause, and a simple approval process turn scope creep into paid work. No awkward conversations. No resentment. No working for free. Just clear agreements and fair payment for the work you actually do.
