Customer Asks for Extra Work: A Tradesman's Reply Guide

A request to paint the hallway as well as the bedroom may be welcome work. It can also change your materials, finish date and next customer's booking. You can be helpful without deciding all of that in a quick conversation on site.

This guide gives UK tradespeople a practical way to respond, with five original messages to adapt. Use your usual quotation and contract process alongside the conversation.

A first reply when you need to check the request

Thanks for asking about [additional work], [name]. I'll check it against the work we've agreed and look at what it would involve. Then I can explain any change to the price or timing before we decide how to proceed.

This acknowledges the request without treating it as automatically included or already approved. If you can give a reliable time for your response, add it. Otherwise, explain the next step without promising a deadline you cannot meet.

Check what the customer is actually asking for

Start with the existing agreement

Read the current quote, specification and relevant conversation before labelling something an extra. The request may be work you already included, a new preference, a separate job or a concern about work already done.

For example, “Can you paint the ceiling too?” needs checking against the quote's room description. “Can you put right the section we discussed?” needs a conversation about the original work. A correction to your own work should not be casually reclassified as a new paid service.

If the original wording is unclear, acknowledge that and discuss the intended scope. Referring to the actual document is more useful than telling the customer that every request costs more.

Ask only the questions that affect the addition

You already have the customer's details and know the original job. Ask about the new part: which area, quantity, finish or item they mean, and whether they want it during this visit or later.

• Decorator: check which additional surfaces and finish are being requested.
• Carpenter: check the number of extra items and who would supply them.
• Plumber or electrician: establish the requested result and what needs assessing before you offer a price.
• Builder: check how the addition connects to the agreed project and any other work being coordinated.

A photo or conversation can clarify the request, but does not replace an assessment you need to make. Keep uncertain details marked as needing a check.

Review your capacity before offering the change

Consider the additional time, materials, access and any return visit. Check whether it affects the original finish date or another booking. A familiar customer or a small-looking task does not establish its price or availability.

The Federation of Master Builders' guidance on extras and pricing recommends defining additions or removals, confirming the cost in writing and getting agreement before undertaking the changed work. Apply that clarity to your own quoting process.

Four more replies for different situations

Replace every bracketed field with verified details. Keep the tone friendly and the next step specific.

When you need one missing detail

I've noted the request for [addition], [name]. Could you confirm [specific scope question]? I need that detail before I can tell you what the change would cost and whether it fits the current visit.

Ask about the addition rather than sending the original enquiry questions again. If the customer's first message already answers your question, use that information.

When you have reviewed the scope, price and timing

Hi [name], I've prepared [quote or change reference] for [specific additional work]. It sets out [what changes], the additional price of [confirmed amount] and [confirmed effect on timing]. Please review it and let me know whether you'd like to agree this change. I'll wait for that agreement before starting the addition.

Only use this after preparing the document. Make the additional charge and any revised total clear in the paperwork so the customer can distinguish them. Follow the confirmation steps your business uses; this message is a prompt to review the proposal.

When it cannot fit into today's work

Thanks [name]. I can't fit [addition] into today's agreed visit. I can review it separately and send you the proposed scope, price and available dates. Would you like me to do that?

If it changes whether you can finish the original work, explain that specifically. Do not promise the original schedule is unaffected until you have checked the dependency.

When the request falls outside your services

Thanks for checking, [name]. [Requested work] falls outside the services I offer, so I won't include it in this job. We can discuss how it affects the arrangements for the work we've already agreed.

You do not need to invent a referral or promise that another tradesperson is available. Be clear about what you can take on.

Keep the original work and proposed addition clear

Keep the issued quote and agreement available. Record the new request as proposed until its scope, price and timing have been agreed through your normal process. Avoid silently changing the existing record so it looks as though the addition was always included.

The Which? Trusted Traders Code of Conduct requires participating traders to provide a revised or additional quote for previously unquoted work before it takes place. That is a scheme standard, rather than a universal form for every trade business.

A short change note can include:

• The original job and quote reference.
• What is being added, removed or replaced.
• The reviewed price and any effect on the agreed timing.
• The proposal's current status and where the customer's agreement is recorded.
• The next action and who is responsible for it.

Illustrative example: Bedroom decorating is booked under the existing quote.
New request: Customer also wants the hallway walls painted.
Status: Proposed addition; finish and timing still to confirm.
Next action: Check the hallway scope and prepare the proposed change.
Record: Retain the original quote and link the new proposal once prepared.

After agreement, update the job note and diary where needed. If the customer declines or leaves the addition undecided, do not mark it approved. Our job sheet template gives you a place to keep these facts with the original work.

Common questions about additional work requests

What if the customer says it was included?

Look through the agreed scope together and ask which part they understood to cover the request. Resolve the difference before proposing a new charge. A calm explanation of the actual wording is more useful than arguing about how quick the task looks.

Can I offer a small addition at no extra charge?

If you choose to, make the exact addition and timing clear. Record that decision so it is not confused with other unpriced requests. It remains your decision about this work, rather than a standing promise for future extras.

What about a regular customer's usual or trade price?

Check the current request and any actual agreement before confirming a figure. Do not copy a previous amount into a different scope just because the customer has used you before. Explain the reviewed price for this particular addition.

Where Traden helps when the requested work changes

Traden keeps customer messages and known job details together for suitable WhatsApp Business and Outlook enquiries. Questions needing your judgement can be handed over with the context ready, and you can handle the conversation yourself.

You can prepare or edit a quote draft and create a revision of an issued quote. Review the current scope and figures: a revision begins from the previous document, so check that the proposed addition is represented correctly. Your decisions about bespoke pricing and availability still need to reflect the actual work.
