How to write a contract renewal letter (with a template)

A contract renewal letter is more formal than a quick email, and that formality does a job. It signals that the relationship matters, it puts the terms on record, and it gives the client something clean to take to whoever signs off the budget.

You do not need legal language or anything stiff. You need a clear, warm letter that confirms the value, states the terms, and makes saying yes easy.

Here is how to write one, and a template you can adapt.

What a renewal letter should do

A good renewal letter covers four things, in this order:

1. Thank the client and remind them of the value. Start with what the last term delivered. This is the most important part and the one people skip.
2. State the renewal clearly. What you are proposing to continue, for how long, and from when.
3. Be specific about terms. The dates, the fee, and anything that is changing. If the rate is going up, say so plainly with a brief reason.
4. Make the next step obvious. Tell them exactly what to do to confirm.

Keep it to one page. A renewal letter that rambles undoes the confidence the format is meant to create.

Tone matters more than length

The client is deciding whether the next term is worth it. A letter that leads with money feels transactional. A letter that leads with results feels like a partnership continuing.

Warm, direct, specific. Write like a person, not a contracts department.

Dear [Client name],

Thank you for a great [past term, e.g. "past 12 months"] working together. Over that time we [one or two concrete results - e.g. "delivered 14 campaigns and grew qualified leads by 30%"], and it has been a genuine pleasure supporting [their company].

I would love to continue. I am writing to propose renewing our agreement for a further [term, e.g. "12 months"], starting [start date].

The terms would be:

• Scope: [brief summary of what is covered]
• Term: [start date] to [end date]
• Fee: [amount] per [month/quarter/year]
• [Any change, e.g. "This reflects a 5% increase from the previous term, our first in two years."]

Everything else stays as it is. If you are happy to proceed, just reply to confirm and I will send the updated agreement to sign.

Thank you again for your trust. I am looking forward to another strong term.

Best regards, [Your name]

Letter or email?

A formal letter suits bigger contracts, longer relationships, and clients who need to pass it up the chain. For lighter, faster renewals an email is often a better fit. If that is your situation, we have ready-to-use contract renewal email templates as well.

Either way, the principle is identical: lead with value, be clear on terms, make confirming effortless.

Send it at the right time

The best renewal letter is useless if it goes out two days before the contract expires. Aim to send it around 60 to 90 days ahead, while there is time for a proper conversation and no pressure on either side.

That only happens if you know the date is coming. Expiro tracks every client contract and reminds you at 90, 60, 30 and 7 days before it ends, so your renewal letter always lands early instead of as a panicked afterthought. Pricing starts at £15 a month.
