Fix It or Reduce the Price? How to Decide After a Survey

After the buyer's property survey identifies issues, the negotiation usually comes down to a straightforward question: should you fix the problem or reduce the sale price? Both approaches have their place, and the right answer depends on the specific circumstances.

This guide provides a structured framework to help you make the decision, with worked examples for the most common defects that arise during property surveys.

The decision framework

When deciding between fixing and reducing, work through the following questions in order.

1. Does the issue affect the buyer's mortgage?

If the buyer's mortgage lender has imposed a retention or requires the work to be done before lending, fixing the issue is often the only practical option. A price reduction does not remove the lender's objection — the work still needs to be done for the mortgage to proceed.

2. How does the repair cost compare to the reduction requested?

Get your own quotes for the work. If the repair cost is significantly less than the price reduction the buyer is requesting, fixing it yourself saves money. If the costs are similar, a price reduction avoids the hassle and risk of managing the work.

3. How long will the repair take?

If the repair can be done in days (a consumer unit upgrade, gutter repair, or minor damp treatment), it is unlikely to delay the sale. If the repair will take weeks (a full rewire, major damp treatment with drying time, or structural work), a price reduction may be faster.

4. Does the buyer have a preference?

Some buyers prefer a price reduction because it gives them control over the work — they choose the contractor, the specification, and the timing. Other buyers prefer you to fix it because they do not want to manage the work after moving in. Ask the buyer (through your agent) what they prefer before assuming.

5. Does the repair provide a guarantee or certificate?

If the repair comes with a transferable guarantee (such as a damp proof guarantee, an EICR, or a knotweed IBG), doing the work yourself adds value beyond the repair itself. The guarantee reassures the buyer and their lender and can make the property easier to resell in future.

Worked examples

The following examples illustrate how the framework applies to common survey findings.

Example 1: Outdated consumer unit

Example 2: Rising damp on rear wall

Example 3: Full rewire needed

Example 4: Roof repairs

Example 5: Subsidence investigation

Repair credits explained

A repair credit is a middle ground between fixing the issue and reducing the price. Instead of changing the sale price, you agree to provide a set amount of money at completion for the buyer to use on repairs.

Advantages of a repair credit

• The headline sale price stays the same, which matters for chain calculations, mortgage offers, and Land Registry records
• The buyer gets the funds to manage the work on their terms
• You avoid the hassle of arranging and overseeing the work
• It can be documented as a separate agreement, keeping the main contract clean

Considerations

• The buyer's mortgage lender must be aware of any repair credit — undisclosed credits can constitute mortgage fraud
• The credit must be formally documented by the solicitors
• A repair credit does not remove a mortgage retention — if the lender requires the work to be done, it still needs to be done

Getting competing quotes

Regardless of whether you choose to fix or reduce, getting your own quotes is essential. Here is how to approach it.

• Get at least two, ideally three, written quotes for the specific work identified
• Use qualified, registered contractors (Part P for electrics, PCA for damp, Gas Safe for boilers)
• Ask each contractor to itemise the work, materials, and any guarantees provided
• Check reviews and references — you need reputable contractors whose work the buyer and lender will accept
• Keep the quotes to present as evidence in negotiation

Your quotes are your most powerful negotiating tool. They provide objective evidence of the true cost and prevent the buyer from overestimating — or inflating — the expense. See our guide on average price reductions after survey for benchmarks on what is proportionate.

Making the decision

There is no one-size-fits-all answer. Use the framework above, consider the specific circumstances, and discuss the options with your estate agent and solicitor. The goal is to find the resolution that protects your financial position, satisfies the buyer and their lender, and keeps the sale moving towards exchange and completion.

In most cases, a combination approach works best. Fix the quick, cheap items yourself (consumer unit upgrade, minor damp treatment, gutter repair) and offer a proportionate reduction or repair credit for the larger, more complex issues. This demonstrates good faith and keeps the negotiation constructive. Remember that the cost of a sale falling through is typically far greater than a reasonable compromise on repair costs.
