Manhole Cover Replacement: Who Fixes a Broken Manhole Cover?

Manhole cover replacement starts with one question: whose is it? If the cover sits on a drain that serves only your property, you replace it. If it sits on a shared sewer, in the road or on the pavement, it almost certainly belongs to the water company, the council or a utility, and your job is to report it. Our drain repairs team replaces covers and frames on private drains across Nottinghamshire and the East Midlands, and this guide covers the rest.

It sets out who owns which cover, what to do about an open or broken one, how to choose the right load class and how a replacement is actually done. For what sits under the lid, read our guide to inspection chambers and manholes.

Is a broken manhole cover dangerous?

Yes. An open, cracked or rocking cover is a fall and trip hazard, and a lid that gives way underfoot can drop someone into a chamber more than a metre deep. Keep people, children and pets away, and put something visible over or around it, such as a wheelie bin or cones. Don't try to lift a broken public cover back into place.

If the cover is on a road or pavement and the hole is open, treat it as an emergency report, not a routine one. Nottinghamshire County Council asks people to phone its Customer Services Centre on 0300 500 80 80 for emergencies rather than use the online form (Nottinghamshire County Council).

Who is responsible for a broken manhole cover?

Responsibility follows the pipe or cable under the cover, not the land it sits on. Use this as a first check:

The shared-pipe rule comes from the 2011 transfer regulations, which moved most private sewers draining to the public network over to the water companies on 1 October 2011. Warwick District Council, in the Severn Trent area, tells residents to call Severn Trent on 0800 783 4444 about a blocked sewer or a broken manhole cover (Warwick District Council). Anglian Water covers most of Lincolnshire. If you are not sure whether a pipe is shared, our guide on who is responsible for blocked drains explains how to tell.

How do I tell whose manhole cover it is?

Read the lid. Most covers in roads and pavements carry a word or logo. Knowsley Council, for example, says manhole covers, cable boxes and cabinets on roads and footpaths are maintained by the utility companies, not the council, and lists who to call for each (Knowsley Council). Common markings include:

• A water company name, or the word sewer: usually the water company.
• BT, Openreach or PO: telecoms. Openreach takes reports of "loose, cracked or missing manhole covers" and gives 0800 023 2023 for emergencies (Openreach).
• Gas, electricity or cable TV names: report to that network operator.
• No marking, inside your boundary: probably your private drain, but check what the pipe serves before you spend money.

Not every cover in a garden is a drain. Water meters, stop taps and old cable chambers also have lids, so don't lift one you can't identify.

Is it the cover or the frame that has failed?

Look before you buy anything. A cracked lid in a sound frame is a simple swap. A frame that has cracked, worked loose or sunk means the bedding underneath has failed, and a new lid on its own will rock and break again.

A common reason for a cracked cover on a driveway is a pedestrian-grade lid that was never meant to take a car. That is worth fixing properly the first time.

Which manhole cover do I need?

Choose by size first (the clear opening of the chamber and the outside of the frame) and then by load class. Covers and frames are tested under BS EN 124, which grades them from A15 to F900 by test load. JDP's guide to BS EN 124 matches each class to where it belongs, and Approved Document H asks for covers that are removable, non-ventilating and "of suitable strength" (Approved Document H, paragraph 2.54).

Two practical points. Match the class of the cover and the frame, because a strong lid in a weak frame is only as good as the frame. And if a garden path might one day become part of a drive, fit B125 now.

Should I choose a recessed or a solid cover?

It depends on the surface. A solid cover has a plain top in metal, concrete or plastic and suits gravel, lawns and tarmac. A recessed cover is a tray you infill with the same block paving, slabs or resin as the surrounding area, so it blends in.

Recessed trays are popular on block-paved drives, but they need the right class (usually B125 for a drive), a properly bedded frame and a lifting key. Approved Document H also says small lightweight covers should be secured, for example with screws, to deter children (Approved Document H, paragraph 2.54). Inside a building, chambers need mechanically fixed airtight covers.

How is a manhole cover replaced?

On a private drain a straightforward replacement usually goes like this:

1. Check ownership so you don't pay to fix a water company or utility cover.
2. Measure the clear opening and frame, and note the class and material of the old cover.
3. Look inside to check the chamber walls, riser and benching are sound. If the frame has sunk, the chamber may be the real problem.
4. Lift the old frame if it is cracked or loose, and break out the old bedding.
5. Rebed the new frame level with the finished surface on fresh mortar or a proprietary bedding compound, or fit a matched riser and frame on a plastic chamber.
6. Make good the surface around the frame in paving, tarmac or concrete, and let the bedding cure before vehicles go over it.
7. Fit and secure the cover, check it sits flat without rocking, and keep the lifting keys somewhere you'll find them.

If the chamber itself is cracked or the pipes into it are damaged, that is a drain repair, and a CCTV drain survey shows what state the pipes are in before you spend money on the top. Our guide to collapsed drain repair costs covers what happens if the problem goes deeper.

When to call a professional

Call a drainage contractor if the frame is cracked, loose or sunk, the chamber walls are broken, the cover is the wrong class for where it sits, or you can't tell whether the drain is private or shared. Call the owner, not a contractor, if it is a water company, council or utility cover.
