However, the total cost can range from £2,000 to £6,000 depending on the complexity of the job.

Factors like location, structural work needed, and alterations to plumbing/electrics can all impact the final price.

While knocking through is a significant investment, it may be more affordable than a full kitchen extension.

Carefully consider the cost versus the benefits of a more open-plan space.

Key Points

  • The average cost is £1,250-£1,750 to knock through the kitchen dining wall.
  • Total costs can range from £2,000 to £6,000 or more.
  • Get quotes from builders as prices vary significantly.

Our Opinion

In our experience, knocking through from the kitchen to the dining room can completely transform the living space.

While it is one of the more expensive renovations, an open-plan kitchen diner adds significant value and creates a light, sociable environment for years to come.

Get quotes from reputable builders to ensure you get quality workmanship for the best price.

Consider any structural changes needed and budget accordingly.

How Much Does It Cost to Knock Through a Kitchen Diner?

Knocking through the kitchen and dining room wall in the UK can cost between £1,250-£1,750 on average. However, prices can range from £2,000 to £6,000 depending on:

  • The complexity of the job
  • Your location – London and the South East tend to be more expensive

Hiring a structural engineer for the project can cost approximately £500. This is because knocking through the kitchen and dining room walls involves additional risks such as:

  • Pipework
  • Plumbing
  • Electrics

Creating an open-plan space through this process can cost a few thousand pounds. But add around £12,000 for structural and building work, and £3,200 for plumbing.

While the cost can be significant, it is often more affordable than other renovation projects. Ultimately, the decision to knock through the kitchen wall should consider the cost and the desire for more open space.

Factors That Affect Knock-Through Costs

Several key factors influence the cost of knocking through between the kitchen and dining room:

  • Size of the wall – Larger walls that need to be removed cost more
  • Construction materials – Brick walls are more expensive than drywall
  • Electrical work – Moving sockets, lights and appliances adds to labour costs
  • Plumbing – Alterations to sinks, pipes and radiators increase the price
  • Structural considerations – Supporting beams, lintels and steels raise the budget
  • Finishing – Replastering, flooring and decorating add extra fees
  • Your location – London and the South East have the highest rates
  • Experience of the builder – Quality tradesmen charge more per day

Getting quotes from several builders provides a clearer picture of potential costs. Ask about their experience with knock-through projects to find the best fit. Understanding these key factors helps set realistic expectations when budgeting to open up your kitchen space.

Removing a Load-Bearing Wall Cost

Knocking down a load-bearing wall that supports the structure above requires careful planning. This specialist work costs more than removing a non-load-bearing partition. The exact price depends on:

  • Inserting a steel beam to support the weight
  • Underpinning foundations for added support
  • Relocating radiators, wiring and plumbing
  • Making good with replastering and decoration

A structural engineer’s approval of calculations and building regulations also bumps up the budget. Expect to pay £3,000-£5,000 for a small load-bearing wall removal. Larger projects with steels and underpinning quickly spiral to £10,000+. Get quotes from structural engineers and builders with experience tackling load-bearing works. Their expertise ensures the knock-through is structurally sound and compliant.

Open-Plan Kitchen Cost Comparison

An open-plan kitchen diner creates a spacious, sociable living area. But this luxury comes at a price. Here’s how costs compare:

Knocking through to an existing room costs less than building an extension. You’ll pay more for structural work to remove load-bearing walls. Extensions require foundations, roofing and electrics. Yet they give you more space to expand your kitchen vision.

On average, expect to pay:

  • £3,000-£8,000 to knock through to a dining room
  • £15,000-£25,000 for a single-storey extension
  • £25,000-£50,000 for a two-storey extension

Get quotes to compare installation costs. Your location, house type and layout affect pricing.

5 Tips to Reduce Your Knock-Through Costs

Knocking through from your kitchen to a dining room can maximise your living space. But it comes at a price. Here are 5 tips to lower your costs:

  • Opt for a simple, clean design without ornate detailing. This reduces construction time.
  • Use bi-fold or sliding doors rather than structural changes if possible. Installation is faster and cheaper.
  • Shop around for tradesmen and get at least 3 quotes. Check reviews to find quality at the best price.
  • Time the work for the off-season when tradespeople are less busy. You may get discounts.
  • Manage the project yourself rather than using a building contractor. But get professional advice on structural changes.

Preparation is key. Draw up plans and get council approval before hiring tradespeople. This will help avoid costly delays or reworking.
