Knock-through walls in Warwick

Planning your knock-through in Warwick

Work inside your Warwick home isn't development, so planning permission doesn't apply — the exception is a listed building, where Warwick District Council would need to give listed building consent. Structural work, new electrics and drainage changes come under Building Regulations.

Keep the completion certificate and engineer's calculations safe, as a buyer's solicitor will ask for them.
Textured ceilings applied before 2000 should be tested for asbestos before they're cut or disturbed.
Removing a load-bearing wall needs a structural engineer's calculations and Building Regulations approval.

Options to consider in Warwick

Non-load-bearing partition removal

Stud or thin block partitions that carry no weight can be removed without steel, once we've confirmed what's above. The work is mostly making good: patching the ceiling and walls, filling the floor where the wall stood, and moving any sockets or switches. It's the quickest and cheapest kind of knock-through.

Kitchen into dining room

A very common knock-through in older houses, creating one sociable room for cooking and eating. It often goes alongside a new kitchen, so the steel position, lighting and sockets are planned with the kitchen layout in mind. Radiators and doors may move to make the most of the longer wall space.

What does your knock-through cost in Warwick?

Guide prices start at £1,200 and run to £14,000 depending on size and specification. Opening up a 3.5 m load-bearing wall between kitchen and dining room in a semi: around £4,500–£6,800.

Before you book in Warwick

Will I get a certificate for the steel beam?

Yes. When building control is satisfied, it issues a completion certificate for the work, and you should keep that with the structural engineer's calculations. A buyer's solicitor will ask for both when you sell, as unapproved wall removals are a common problem in house sales. Steel and other products carry their manufacturers' terms, which are set out in your quote.

Which postcodes in Warwick do you work in?

We cover CV34 and the streets around them. If you're on the edge of Warwick, neighbouring Leamington Spa and Kenilworth are covered too.

How do I know if a wall is load-bearing?

You can't be sure by looking, so we check on site. Clues include floor joists running across the wall rather than alongside it, a wall directly above on the next floor, or solid brick rather than hollow stud. Even a wall that seems light can carry a load in older houses. A structural engineer confirms it, and the calculations form part of the Building Regulations approval.

Does Warwick District Council need to approve my knock-through?

Not for planning — internal work isn't development unless the house is listed. Building Regulations approval is needed for structural work such as removing a load-bearing wall, through Warwick District Council or a registered building control approver.
