About our kitchen-diner knock-throughs service in Newport
Kitchen-diner knock-throughs remove the wall between a kitchen and a dining room to create one open-plan room, with a steel beam carrying whatever the wall supported. The work is planned around the kitchen itself: gas, water, waste and extraction runs, where units and any island will go, and how the ceiling should look once the steel is in.
Across Newport, kitchen-diner knock-throughs usually come up when people want more light, a better layout or a way through to a new extension. That covers every postcode district in the area. Whatever the reason, the beam is sized from calculations and the work is inspected before anything is covered.
Key points for your project
- A flush beam sits up within the depth of the ceiling so the kitchen and dining ceilings run as one flat surface. It suits continuous downlights and long runs of wall units, but each joist has to be connected into the beam, which adds labour.
- Settle the kitchen layout before the steel is designed. If the engineer needs a column or a deeper beam, it is far easier to plan an island, tall units or the hob position around it at drawing stage than after the units are ordered.
- Keep the structural calculations, the building control completion certificate and any gas or electrical certificates together. When the house is sold, the buyer's solicitor will usually ask for evidence that the knock-through was approved and signed off.
- A gas hob or cooker supply often runs along or through the wall being removed. By law, any work on gas pipework must be carried out by a Gas Safe registered engineer, so the pipe is capped or rerouted by one before the wall comes down.
- If the kitchen also opens onto the hallway, the change can affect the escape route from the bedrooms. Building control checks how people would get out in a fire, and smoke alarms, a fire door or other measures may be required as part of approval.
Four stages, one team
Survey in Newport
We visit, look at the wall and what sits above it, measure the opening and note services, access and how the steel can be brought in.
Engineer's design
A structural engineer sizes the beam, padstones and any posts, and sets out the temporary support needed while the wall is out.
Building control
We submit the application or notice to Newport City Council under the Building Regulations as they apply in Wales, before work starts.
Install and sign-off
Props go in, the opening is formed, the steel is set and packed, building control inspects it, and we make good.

Building rules for Newport
Welsh building regulations treat beams and new openings as controlled building work. We apply to Newport City Council on your behalf before anything is removed, give the commencement notice the 2026 Welsh rules require, and the steel is checked before it is boxed in.
Where the steel bears into a wall shared with next door, notice must be served under the Party Wall etc. Act 1996. If your neighbour dissents, surveyors agree how the work is done before it starts.

Questions about kitchen-diner knock-throughs in Newport
How much do kitchen-diner knock-throughs cost in Newport?
As a guide, budget £2,300–£5,450 including VAT for kitchen-diner knock-through in Newport, based on published UK cost guides adjusted for prices in Wales (-9%). The exact figure depends on the span, what the wall carries, access and the finish, and is fixed in writing once the scope is agreed.
Do you cover Newport for kitchen-diner knock-throughs?
Yes. We carry out kitchen-diner knock-throughs in Newport. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.
Should I do the knock-through before or after fitting a new kitchen?
Before. The steel, any column, the floor levelling and the plastering all need to be finished first, so the kitchen fitter works in a dry, square room with services already in position. Fitting units and then taking out a wall risks damage and rework, and the beam position can affect where wall units go.
Do I need permission from my landlord or freeholder to open up a kitchen?
If you own a leasehold flat, usually yes. The lease will normally require the freeholder's or landlord's written consent for structural alterations, so get that before any work is booked. Freehold houses do not need this, and planning permission is not normally needed for internal changes unless the building is listed.
How long will I be without a kitchen?
The structural work itself usually takes three to six working days, and the kitchen is out of action during that time. After that come plastering, drying, flooring and the kitchen fit, so the overall period without a finished kitchen depends mostly on your fitter's programme and when the units are delivered.
Is the wall between my kitchen and dining room load-bearing?
It often is, particularly in older semis and terraces where it supports the bedroom floor joists. The clearest signs are joists bearing on it from above and a wall in the same position upstairs, but only an engineer's site check confirms it. We arrange that check as part of the survey and design stage.
