Structural Engineering Calculations in London


If you're planning a refurbishment, extension, or new build in London or the surrounding areas, appointing a reliable structural engineer in London is crucial for your construction project. Accurate engineering calculations are essential, whether you need to remove a load-bearing wall, design a steel beam, or require detailed structural drawings for planning permission. Our professional team of Chartered Structural Engineers and Surveyors offer comprehensive civil and structural engineering services for residential projects, commercial properties, and other engineering projects across Greater London.

Understanding Engineering Calculations


Engineering calculations are fundamental to the safety and success of every construction project. These calculations involve assessing forces, materials, and structural loads to ensure compliance with UK building regulations. Our reputable structural engineering services include:

  • Steel beam and lintel design

  • Foundation design calculations

  • Structural timber assessments

  • Load path analysis and stability checks

  • Structural wall and column evaluations

Whether you’re planning a rear extension, opening up your space, or carrying out internal structural alterations, our structural engineers provide structural solutions tailored to your project’s requirements.


What does a Structural Engineers report contain?


A Structural Engineer Report, also known as a Full Structural Engineers Report, General Structural Inspection (GSI), Single Site Inspection (SSI), or Single Defect Report, provides a comprehensive evaluation of a property's structural integrity. This detailed assessment is essential for homeowners, prospective buyers, and property investors, offering clarity on the structural condition and highlighting any necessary repairs or potential issues.

Typically, these reports become particularly valuable when you're selling, refinancing, or planning significant property alterations, such as extensions or renovations. Conducted by experienced structural engineers, the inspection gives you a clear, impartial understanding of the property’s current state, helping you make informed decisions and safeguarding your investment.

During the inspection, the structural engineer will visually examine critical load-bearing elements of your property. This includes an assessment of foundations, roofs, and any accessible structural components to identify signs of damage, wear, or potential structural weaknesses. The evaluation may also extend to exterior surroundings, analysing potential hazards posed by trees, drainage, or adjacent structures, guided by civil engineering principles and local building regulations.

To maximise the effectiveness of the inspection, you'll be asked to provide the structural engineer with relevant background information, including any previous surveys, known property issues, or specific concerns you might have. Equipped with this information, your engineer can efficiently plan the inspection and prepare a thorough and tailored report.

The final report will clearly outline any structural defects discovered, providing insights into their nature and potential causes, alongside professional recommendations for repairs or remedial actions. Crucially, it will confirm whether the property is structurally sound, ensuring you have peace of mind and potentially saving significant costs and stress in the future.

Engineering Calculations Cost


The cost of engineering calculations can vary considerably based on several key factors, including the scale and complexity of your project, the number of site visits required, the specific purpose of the calculations (such as renovations or party wall agreements), the size and type of property, and its geographic location. Typically, structural engineers in London, especially East London, charge higher fees compared to other areas due to regional demand and operating costs.

For instance, a comprehensive structural engineering calculation and report for a smaller property might typically cost around £950, involving just a few hours of detailed assessment and report preparation. Conversely, if you require a report focusing on one or two specific structural defects or concerns, the cost could be around £600.

Many structural engineers provide fixed-price quotations tailored specifically to the scope of your project. Depending on the extent and complexity of the calculations needed, these fixed prices can range widely—from approximately £400 for simpler evaluations to upwards of £2000 for more comprehensive or complex assessments. It's also important to note that additional fees might be applied by some engineers for supplementary services such as preliminary walk-around surveys, generic structural inspections, or detailed inspection reports.

To avoid unexpected expenses, it’s advisable to clarify the full scope of services and the inclusions of the quotation before proceeding. Ensure your quotation clearly specifies the total cost for all required services, including site visits, calculation preparation, drawings, or plans, and confirm that no hidden charges are applicable.

For reliable and accurate budgeting, we recommend seeking quotations from recommended structural engineers—ideally through professional recommendations or trusted personal referrals—to ensure you find the most suitable and cost-effective solution for your specific project requirements.

Scott did the survey on the day and he was incredibly thorough - it's given us great peace of mind for our house move. The report he gave was detailed, well laid out with excellent photographs of every aspect of the house and surrounds.
