Pre-Purchase Drain Survey across Bath

A pre-purchase CCTV drain survey is one of the most useful pieces of due diligence when buying a property in Bath, and one of the most overlooked. Standard homebuyer and building surveys do not include the drains, yet drainage defects routinely cost thousands of pounds to put right and are invisible from the surface. This matters more in a city like Bath, where a large share of the housing stock is Georgian and Victorian and still drains through original clay or cast-iron pipework laid over a century ago. Clay pipes crack and their joints open up as the ground moves, and the mature trees that line so many of Bath's period streets send roots straight into those open joints in search of water. Our pre-purchase survey uses a high-definition CCTV camera to inspect the full accessible drainage system, from the property out to the point where it connects with the public sewer. We record footage of every run and identify cracks, fractures, root ingress, displaced joints, bellied sections where water sits, and any misconnections. Crucially, we also flag whether any part of the property — an extension, conservatory or garden room — has been built over or close to a public sewer, because that requires a build-over agreement with Wessex Water, the sewerage undertaker for Bath and Somerset. A missing build-over agreement is exactly the sort of thing a buyer wants to know about before exchange, not after. Everything is graded to a recognised standard. We code defects using the WRc Manual of Sewer Condition Classification (MSCC5), the same system professional drainage engineers and insurers use, so a Grade 1 minor blemish is never confused with a Grade 5 structural failure. You receive a written PDF report with annotated stills, a schematic drain map showing pipe routes and where each defect sits, and a plain-English summary of what it all means and what any repairs would cost. The report is produced to a standard your solicitor, surveyor, lender or insurer can rely on. Having it before exchange gives you the evidence to negotiate a price reduction, make repairs a condition of sale, or walk away from a property with serious drainage problems.

Signs you need pre-purchase drain survey help

  • ✓ You are buying a Georgian, Victorian or other period property in Bath with original clay or cast-iron drainage
  • ✓ You are about to exchange contracts and want full visibility of the drainage before you commit
  • ✓ There are mature trees close to the property that may have driven roots into the pipe joints
  • ✓ An extension, conservatory or garden room may have been built over or near a public sewer (a Wessex Water build-over matter)
  • ✓ The homebuyer or building survey flagged damp, subsidence or drainage concerns
  • ✓ A previous buyer withdrew and you want to understand why

Our process

  1. 1.
    Request online

    Send the property address and your target exchange date through the form. There is no phone tag — we come back to confirm a survey slot, usually within a few days.

  2. 2.
    Full system survey

    We access the drains through external manholes and chambers — no preparation needed on your part — and feed the CCTV camera through every accessible run, recording HD footage of pipe condition, joints and connections.

  3. 3.
    Grade and map

    Our technician reviews the footage, grades each defect to the WRc MSCC5 standard, maps the pipe routes, and flags any build-over or connection issues that need a Wessex Water agreement.

  4. 4.
    Report and support

    You receive the PDF report — annotated stills, drain map, condition grades and repair guidance — in a format your solicitor can use, typically within 24 hours. We are on hand to explain the findings and quote for any repairs.

Pricing guide

The cost of a pre-purchase CCTV drain survey depends on the size of the property and the extent of the drainage network — larger period properties with multiple runs, outbuildings or shared drainage take longer to survey. Request a fast, fixed-price quote online; the price is confirmed before we attend and includes the survey, the annotated footage, the drain map and a full written report, with no call-out fee.

Pre-Purchase Drain Survey — frequently asked questions

Do I need a drain survey before buying a Georgian property in Bath?

It is strongly advisable. Most of Bath's Georgian and Victorian houses still drain through original clay pipes that are well over a century old, and these are prone to cracking, joint displacement and root ingress from the mature street trees the city is known for. A standard building survey does not inspect the drains, so a CCTV pre-purchase survey is the only way to see their true condition before you commit. It routinely pays for itself either in peace of mind or in negotiating room.

What is a Wessex Water build-over agreement and why does it matter?

If a previous owner built an extension, conservatory or other structure over or close to a public sewer without permission, the water company — Wessex Water in the Bath area — can require costly remedial work or a retrospective build-over agreement. Our survey identifies where drains run and whether anything has been built over them, so you can raise it with the seller before exchange rather than inheriting the problem.

When should I book a pre-purchase drain survey?

Ideally after your offer is accepted but before you exchange contracts. That gives you time to negotiate on the findings or withdraw if serious defects are uncovered. Most surveys can be arranged within a few days of booking, and the report is delivered within 24 hours of the survey.

What happens if the survey finds problems?

You use the graded report as leverage: negotiate a reduction in the purchase price, make repairs a condition of sale, or factor the repair cost into your decision. Because every defect is graded to the MSCC5 standard, a minor cosmetic issue is clearly distinguished from a serious structural one, so you are negotiating on evidence rather than guesswork. We can provide repair quotes for anything found.
