Yes, you can. Buyers renegotiate after a survey all the time, and sellers expect it when real problems turn up. What makes the difference is evidence. “The survey mentioned the plumbing” is easy for a seller to brush off. A written report with photos, listing exactly what needs doing and why, is much harder to ignore.

Why a vague survey note isn’t enough

A surveyor will often flag the boiler or plumbing and recommend further investigation. That’s useful, but it doesn’t tell you what’s actually wrong or how big the job is. Without that, you’re guessing at what to ask for, and the seller can simply say no.

It works the other way too. A survey that doesn’t mention the plumbing isn’t proof there’s nothing wrong: the surveyor looks, but doesn’t test. That’s why we’d recommend an inspection whatever your survey says.

A plumbing or boiler inspection fills that gap. Our engineers test what the surveyor could only look at, then set it all out in a report you can share with your estate agent and the seller. You can read more about the difference in does a Level 2 or Level 3 survey check the boiler and plumbing?

Small faults add up

Most inspections don’t find one disaster. They find a list of smaller jobs, and it’s the list that matters. On a recent inspection, the kitchen tap looked fine at a glance. Close up, the cap was missing from the hot handle and the inside was worn, and the base was dull and corroded. On its own that’s a small job. Add the cracked grout and failed sealant around the bath, a gap opening up along the bath panel, and mould along the sealant at the basin, and the buyer was looking at a new tap, a reseal of the bathroom and some investigation behind the panels.

None of those would stop a sale. Together, they’re a real cost the buyer would have to pay for soon after moving in, and that’s a fair thing to raise with the seller.

How buyers use our report

Every inspection ends with a written report: what we checked, what we found, photos of each problem and what needs doing. Buyers use it to:

  • ask for a price reduction that reflects the work needed
  • ask the seller to put things right before completion
  • plan and budget for the work if they go ahead at the agreed price
  • walk away if the problems are bigger than they’re willing to take on

Each item of work comes with a guide price (hidden here), so the buyer knows the likely cost.

As an example, one buyer we inspected for used our report to go back to the seller, who accepted the breakdown of work needed. The buyer saved about £6,000 to £7,000 on the price. We can’t promise any saving, because every property and every seller is different. What a clear report does is make sure any conversation with the seller starts from the facts.

Tips for negotiating after a survey

  1. Act quickly: book the inspection as soon as the survey comes back, so you’re not holding up the chain.
  2. Stick to facts: share the report, not just your worries. Sellers respond better to a clear list than to a general complaint.
  3. Get the work priced: a reduction is easier to agree when it’s based on real quotes for the work in the report.
  4. Separate the urgent from the cosmetic: a leaking waste or an unsafe boiler matters more than tired grout.
  5. Go through your estate agent: they’ll put your case to the seller and know what’s likely to be accepted.

Why the report needs a specialist

A report is only as good as the inspection behind it. Spotting a slow leak behind boxing, a perished joint under a worktop or a cylinder that hasn’t been looked after takes experience, not just a quick look. Our engineers have over 29 years of plumbing and heating experience across Birmingham and Solihull, and years of specialist leak trace and access work behind them. Alongside a careful visual inspection, we use thermal imaging, leak detection equipment and moisture meters where they help, without opening anything up.
