Homebuyer Drain Surveys In Derby

A standard mortgage valuation or building survey doesn't look inside the drains. Cracked, root-damaged or collapsed pipes are hidden underground, and repairs to a private drain fall to the new owner. Older houses with clay pipes, homes near mature trees and properties that have been extended are the ones most worth checking.

In Derby the public sewers belong to Severn Trent Water. Our report shows where the private drain ends, so you know which defects would be yours to fix and which the water company is responsible for. If the survey finds a problem, we can quote for the drain repair so you have a figure before you negotiate.

Derby is cheaper than the East Midlands average. The ONS put the city's average price at £207,000 in July 2026 (provisional), against £242,000 for the region. First-time buyers paid an average of £185,000, and terraced houses averaged £167,000. At those prices a collapsed drain or a run full of roots costs a meaningful share of a deposit, and once you've exchanged contracts it's your bill.

The housing stock is old. Valuation Office Agency figures show that 16,760 of Derby's 114,860 homes were built before 1900 and another 16,180 in the 1930s. More than a third were built before 1940, so many buyers here are looking at drains that have been in the ground for more than 85 years. Census 2021 also showed private renting in Derby rising from 16.8% to 21.3% of households since 2011, so many buyers are landlords who will be responsible for the drains under a tenanted home.

A homebuyer drain survey runs a camera through every accessible run before you exchange. You get a written report grading each defect, with stills and footage, which you can pass to your solicitor or surveyor or use to agree a lower price. We agree the price when you book.
