Considering hiring a professional structural engineer in London but worried about the cost of a structural engineer? The fee for these experts plays a big part in project budgets for your building project.

This article breaks down factors like project size, value and complexity as well as engineer qualifications and experience.

What does a Structural Engineer do?

A structural engineer will calculate what is required to build or remove structural elements in a property safely.

They are involved in surveying movement cracks (subsidence), load bearing walls, removing a chimney breast, loft conversions, building an extension and general home improvement (see Home Extension Cost Considerations).

Factors Affecting the Cost of Hiring a Structural Engineer in London

Please read Reasons Why You Need to Hire a Structural Engineer before you contemplate the charges in London, which can change for many reasons. For example, how big or complex your project is, and where in London you are, play a big role.

Project complexity

If your plan has unique design features or needs materials that are difficult to source, this will make the work harder and therefore more expensive.

Consider a basement conversion or multiple steel beams in London; these items could make everything more difficult to navigate. A problem with the structure of your property is common in such projects where you need to calculate the stability safely for your contractor.

Building regulations and licences are also integral. Your local planning authority may require special designs as a condition of your planning permission.

Size of the project

The size of the project determines how much you'll pay a structural engineer in London. For bigger projects, like adding floors to buildings or working on large basements, the costs go up.

This is because these tasks need more work, including planning and compliance with building regulations. Each step might need different kinds of drawings or even special computer programmes to see if the ideas will work. The bigger your dream project, the more you'll invest.

For small changes, like removing walls to make rooms bigger or adding doors and windows, the cost might not be as high. Yet, even smaller jobs require a trained eye to keep houses safe and standing strong.

Engineers have tools and knowledge for all sizes of work – from simple tasks involving rolled steel joists (RSJs) and I-beams for open space living areas to redesigning a property entirely and extending.

Engineer’s experience and qualifications

Engineers who have worked for many years and have a lot of good training often ask for more money.

They might also have special certificates or skills, like knowing how to design blocks of flats, which makes their hourly pay higher.

You may need them to specialise in drawing up a specification brief to identify accurate calculations for the ceiling and loadbearing walls as part of their investigation, for which they would advise you and your builder or architect on in accordance with their professional indemnity insurance.

Remember to check that they have a valid insurance policy!

Much like a how a building surveyor is chartered under different accreditation bodies like RICS, CIOB and RPSA, your engineer should have IStructE or ICE accreditation for them to provide structural repair recommendations.

Hiring someone who's just starting out could cost less, but picking a seasoned expert means your project is more likey to meet top safety and quality standards. Make sure your structural engineer can provide structurally sound solutions supported correctly by specialist calculations for your home improvement project.

Geographical location within London

In London, where you plan to build or renovate makes a big difference in cost. Central London has higher fees because it costs more to live and work there and it may be more difficult to get the right equipment on site. The farther out from the centre, the less you might pay.

Also, some places are harder to reach than others. If your project is tucked away in a narrow street or somewhere without good road access, this could mean paying more for the time it takes workers and supplies to get there.

Each property assessed in London— particularly Westminster with its historic buildings—brings different costs and recommendations based on these challenges.

Typical Fee Structures: Structural Engineers Costs

Structural engineers can charge in different ways. They might ask for money based on the hours they work, set a single price for the whole task, or take a percentage fee of your project's total cost (e.g. 10%).

Hourly rates

Hourly rates for a structural engineer in London generally fall between £100 and £250. This cost depends on how hard the job is and the engineer's skills. High skill and difficult jobs mean higher prices.

Every hour, you pay for expert advice on buildings, renovations, or checking if structures can be built correctly. Paying more for an experienced structural engineer saves money in the long run by avoiding costly mistakes.

They look at concrete foundations, loadbearing walls, and make sure your project meets safety regulations. So, they are a worthwhile investment.

Flat fees for specific projects

Structural engineers London can charge flat fees for certain jobs. These fixed prices can be anywhere from £500 to many thousands of pounds, depending on what needs doing. The cost is usually set by the project scope.

Choosing this payment method makes budgeting easier since you know the cost upfront. For homeowners or businesses in London needing a structural engineer report or help with residential construction, knowing there won't be any surprise costs later is a relief.

It's clear and straightforward – you pay in tranches for the whole job. This may involve checking trusses after water damage or drawing up technical plans for new builds.

Percentage-based fees

Moving from flat fees to percentage-based fees, the way you pay for bigger building work is a bit different.

Big projects often use percentage-based fees. Here's how it works—you pay the engineer a part of the total cost of your build. This is usually between 1% and 5%. So, if you're spending a lot on construction, the engineer's fee goes up too.

Larger builds like skyscrapers or designing major parts of cities often deal with these kinds of payments. It makes sense for big jobs because the more complex and pricey the project, the more work the engineer has to do.

They might need to conduct site visits frequently or make lots of design changes until everything meets quality standards.

Additional Costs Associated with Hiring a Structural Engineer

Hiring a structural engineer comes with initial extra costs, but larger savings. You might need to pay for more drawings or site visits, which they will clarify with you.

Consulting and design modifications

Consulting and design changes involve talking with experts to make plans better. This can mean extra costs for different planning and advice services. Sometimes, a project needs new ideas or changes part-way through.

A structural engineer in London must then redo parts of the plan. These changes depend on what the project needs more of or less of. The cost varies too. Every project is unique - adjustments in design are often where innovation meets necessity.

Making these adjustments might mean extra meetings, looking at the site again, or using Building Information Modelling (BIM) to see if the new ideas work well.

Site visits and inspections

Site visits and inspections are key tasks for a structural engineer. They check to make sure everything meets safety standards. These checks might cost extra because they can include travel costs and time charges. Engineers need to travel to the site, spend time inspecting it, and sometimes come back multiple times.

Next, we will review planning fees and reports.

Planning application calculations and reports

Getting planning permissions is a big milestone.

You need the right documents to show your project is safe and follows planning rules. This is where a structural engineer in London steps in to do special calculations and write engineering reports for your application. These documents prove your project is viable.

For this work, engineers use their skills plus tools like computer-aided design software (CAD) to create detailed drawings that match what the local council wants to see. Without these, getting planning permission on your building or renovation project could take longer or even stall.

Tips for Reducing Structural Engineer Costs

To keep costs in check, be clear about what you need from the start.

Getting prices from a few engineers and checking contracts for extra fees can also help save money.

Clearly define project scope

Defining the project scope with your structural engineer in London means you set out exactly what needs doing. This limits disputes arising. You write down all tasks, from technical drawings to site visits so as to budget accordingly.

Also, you include how often you need updates and when each task should be done by. This plan becomes a map for your work together.

Plus, this clarity allows comparing quotes from different engineers easier since you're asking each one for a price on the same list of tasks.

Obtain quotes from multiple engineers

Getting quotes or tendering from several structural engineers helps make sure you're getting fair pricing, but we do this work for you by ensuring you receive the best priced quotation from the outset.

Each engineer or firm might price their services differently: some may charge hourly, while others offer flat rates for certain jobs. We will explain the difference to you.

By comparing these quotes, you can see the range of prices and what each service includes. This step also lets you check out the varied services on offer. For instance, some engineers in London might have better experience with high-rise buildings than others.

So, apart from just looking at the cost, this process allows you to match your specific project needs with the right expertise.

Check for hidden costs in contracts

Make sure to read contracts carefully. They can have extra costs that you might not see at first. These could be for more site visits, changes in design, or added reports needed for planning permission.

It's good to ask for a clear list of what you're paying for. Sometimes, engineers add fees if the project takes longer or needs more work than planned.

Why You Need a Structural Engineer

Picking the right structural engineer is key to making sure your building meets safety rules and avoids serious errors in construction. Using one saves you time and money by flagging any potential issues in your dwelling.

Building Surveyor Recommendations

Often, if you had a buyers survey (RICS Level 3 Report) carried out, your surveyor may have recommended further investigation of, say, a structural defect in the loft as part of their initial obvservations.

Your engineer can carry out a site visit to assess the damage and possible causes relating to movement or cracking walls, sagging ceilings or roofline, etc. to ensure your project will comply with building regulations.

If the building may be suffering from progressive movement, you may need a Monitoring Survey.

Compliance with safety standards and regulations

Choosing a qualified structural engineer in London means your project follows all UK safety standards and laws.

Accreditation under the Institution of Structural Engineers (IStructE) or Institute of Civil Engineering (ICE) shows they meet high standards for their work.

You can read this article on whether civil engineers can do structural engineering.

Avoidance of costly construction mistakes

Hiring a skilled structural engineer in London means you cuts down risks and make sure the project adheres to the budget from start to finish. This will prevent serious defects arising pre/post-completion and limit claims against you.

Further explanation on what a Structural Engineer Survey is for can be found in the aforementioned resource.

Party Wall Surveyor Recommendations

If you are undertaking works to the party wall, your party wall surveyor will want to see engineering calculations and may request the services of a chacking engineer to verify these (see Why Checking Engineers Are Required Under the Party Wall Act).

Do I need a Building Project Management Surveyor?

A Building Project Management by a surveyor who can oversee the entire build and coordinate between engineer, architect and contractor as a contract administrator is good practice.

This means you do not have to do all of the work by yourself as the employer, meaning you conveniently reduce risk and delegate work effectively (see Why Hire A Project Manager?).
