About our kitchen-diner knock-throughs service in Merseyside

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.

We carry out kitchen-diner knock-throughs throughout Merseyside, for homeowners, landlords and builders who need the structural part done properly. Towns we cover include Southport, Bootle and Kirkby, among other places in the area. You get an itemised written quote that shows the calculations, approvals, steel, labour and finishing as separate lines.

What to expect

  • The structural price depends mainly on the span, what sits above and how the beam ends are supported. Kitchen-related extras, such as moving gas, relocating a soil pipe or rerouting ducting, are listed as separate items so you can see what each one adds.
  • 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.
  • Older kitchens can hide asbestos in textured ceiling coatings, floor tiles, boxing around pipes or the backing of old heaters. In buildings from before 2000 it must be identified before the fabric is disturbed, so a survey of the affected area is arranged first.
  • 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.
  • Sinks and dishwashers usually sit on an outside wall, but supply pipes and waste runs sometimes cross the internal wall. Moving the sink to an island means planning a waste route with enough fall under the floor, which affects how the floor is prepared.

From survey to sign-off in Merseyside

  1. Free visit

    A short visit to Merseyside to see the job, agree what you want and check the bearings, floors and services that affect the design.

  2. Calculations

    The engineer's calculations and a simple drawing are prepared for your opening and shared with you before anything is ordered.

  3. Building control

    We submit a building notice or full plans application to the local council's building control team, so approval is in place before the wall is touched.

  4. Steel in, made good

    On site we prop, open up, fit and pack the steel, then fire protect, box in and plaster once the inspection is done.

Figures include our approximate regional adjustment for prices in the North West (-4%) and are rounded. How these figures are worked out.

Building control and neighbours in Merseyside

For Merseyside, building control is provided by the local council's building control team, or by a registered building control approver if preferred. We send them the engineer's calculations with a building notice or full plans application and book the inspections. Work done without approval can cause problems at sale and is far dearer to put right later.

If the beam bears into a wall you share with a neighbour, the Party Wall etc. Act 1996 applies, and a party structure notice must be served at least two months before that work starts. We arrange this through a party wall surveyor.

Kitchen-diner knock-throughs in Merseyside: your questions

What happens at the survey visit in Merseyside?

We look at the wall, the floor and ceiling either side and what sits above, measure the opening you want, and note cables, pipes and access for the steel. It usually takes under an hour and there is no charge.

Which towns in Merseyside do you cover?

We cover towns including Liverpool, Birkenhead, St Helens and Southport, plus the villages and smaller towns around them.

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.

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.

Can the steel beam be hidden in the ceiling?

Yes, a flush beam can be set into the ceiling void so there is no step between the kitchen and dining ceilings. It needs enough joist depth and more labour to connect the joists to the steel, so it costs more than a downstand. The engineer confirms whether it is possible in your house.

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.

How much do kitchen-diner knock-throughs cost in Merseyside?

As a guide, budget £2,400–£5,750 including VAT for kitchen-diner knock-through in Merseyside, based on published UK cost guides adjusted for prices in the North West (-4%). 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.
