What makes commercial drainage different
Commercial drains are often longer, deeper and more complex. They may serve many users and carry more waste. As a result, faults can cost more to fix.
Some sites share drains with neighbours or run under car parks. Records may be missing or out of date. A survey helps fill the gaps.
Pre-acquisition commercial drain survey
Before you buy a commercial building, a drain survey shows hidden faults. It can reveal cracks, roots or collapsed sections. Since repairs can be costly, this information helps you plan.
Share the report with your solicitor and advisers. You may use it to negotiate the price or ask the seller to fix faults. However, it is only one part of your checks.
Drainage management surveys for portfolio landlords
Landlords with many properties can survey drains on a schedule. This builds a record of each site. Over time you can spot weak points before they fail.
A regular plan helps with budgets, because you can spread repair costs. It also helps when tenants report problems, since you already know the drain’s history.
Food business drainage surveys
Kitchens send fat and food waste into drains. A camera survey shows how much grease has built up. It also shows whether a grease trap is working.
Check what your water company and local council expect from food businesses. Rules can differ by area. A survey report is a useful record to keep.
Insurance and commercial drainage
Insurers may ask about drain condition and upkeep. A recent report can show that you look after the property. Ask your insurer what evidence they accept, because policies differ.
Keep all survey reports and repair records together. They can help if you need to make a claim later. Read your policy for any maintenance conditions.
Drainage condition surveys at lease renewal and lease end
At the start or end of a lease, a drain survey sets a clear record. It shows the condition of the drains on a given date. This can prevent disputes about who caused damage.
Check your lease to see who is responsible for the drains. Ask a solicitor if the wording is unclear. A survey does not decide responsibility, but it gives useful facts.
What to specify in a commercial drainage survey contract
Say which drains you want surveyed and to what length. Ask for footage, a written report and a plan. Agree who cleans the pipes first, and what happens if the camera cannot pass.
Agree the timing too, since some sites cannot close. You can ask for a free quote and we will pass your details to a local engineer. Our page on CCTV drain survey has more detail.
