The Complete Guide to Hiring a House Extension Builder in London

Planning to extend your home in London? One of the biggest steps is hiring the right house extension builder. With so many options available, it can be hard to know where to start. This guide breaks down everything you need to consider, making the process easier and helping you find the best extension builders in West London.

Why Hiring the Right Builder Matters

A house extension is a big investment. Whether you're adding a new kitchen, creating more living space, or building an extra bedroom, the quality of your builders work will directly impact your homes value, comfort, and appearance.

A good builder will:

• Understand your vision

• Provide accurate timelines and quotes

• Handle permissions and regulations

• Deliver quality work on schedule

On the other hand, choosing the wrong builder can lead to delays, poor craftsmanship, and hidden costs.

Step 1: Define Your Project Clearly

Before hiring anyone, get clear on what you want. Do you need a rear extension, side return, wraparound, or loft conversion? How much space do you want to add? Whats your budget?

Write down your goals, ideal timeline, and must-have features. Having a clear brief will make it easier for builders to provide accurate quotes and advice.

Step 2: Research Local Builders in London

Search online for "house extension builders in London" and shortlist companies with:

• Positive reviews and testimonials

• A solid portfolio of completed projects

• Experience with similar types of extensions

• Transparent websites and contact info

Ask friends, neighbours, or colleagues if they have recommendations. Word-of-mouth referrals are often the most reliable.

Tip: Start with established names like Total Build Services, who specialise in house extensions across London and have a strong track record of satisfied clients.

Step 3: Check Qualifications and Insurance

Always check that the builder is fully insured and qualified. Look for:

• Public liability insurance

• Professional indemnity insurance

• Memberships with trade bodies like FMB (Federation of Master Builders)

Ask for proof of these before signing any contract.

Step 4: Request Quotes and Compare

Invite 23 shortlisted builders to visit your home and provide a written quote. A good quote should include:

• Detailed cost breakdown

• Materials and labour

• Timeline

• Payment schedule

Dont just go with the cheapest option. Instead, look for best valuesomeone who offers quality, clear communication, and fair pricing.

Step 5: Ask the Right Questions

During consultations, ask builders:

• Have you worked on similar extensions in London?

• Do you handle planning permissions?

• Who will manage the project on-site?

• Can I speak with past clients?

• What happens if there are delays or extra costs?

The more open and honest their answers, the more trustworthy they likely are.

Step 6: Get a Clear Contract

Once youve chosen your builder, sign a contract that covers:

• Project scope and timeline

• Total cost and payment terms

• Warranty details

• Responsibilities (yours and the builders)

Never rely on verbal agreements. A written contract protects both sides and avoids confusion.

Step 7: Stay Involved During the Build

Check in regularly with your builder during the project. A good builder will keep you informed about progress, delays, and any unexpected issues.

Trust is key, but dont be afraid to ask questions or request updates. Its your home and your investment.

Step 8: Inspect the Finished Work

When the build is done, walk through the space with your builder. Make sure everything works properly and matches the agreed plan.

Create a snag list of any small issues to fix before making the final payment.

Pro Tip: Builders like Total Build Services offer aftercare and post-project support to ensure youre happy even after the job is complete.
