5 Top Tips for Choosing the Right Company for Your Extension

5 Tips for Choosing the right company for your extension

Our homes are our greatest asset. Whether that’s a place to bring family and friends together to make lasting memories, or a space to grow, invest in, and shape around your lifestyle—they matter. Yet, many homes are too small for how we want to live. A 2024 survey by Confused.com shows that around 32% of UK homeowners plan to renovate their homes. 

Choosing the right company is one of the most important decisions you will make—and it can make or break the whole experience.

Here are our top 5 tips to help you choose a company who’s not just good on paper, but great in practice.

1. Get multiple quotes

Get quotes from a range of different companies. Large national firms often have showrooms and run big marketing campaigns. This can make you feel more secure. But they have to factor the cost of expensive overheads into their prices. The end result is that customers often experience heavy pressure sales. In contrast, a smaller local company can offer a more personal service. 

By speaking to different companies, you will hear new ideas. You can explore more options, so you’ll feel sure about the best choice for your home. 

2. Check Their Track Record

Don’t just look at glossy photos—ask to see real past projects. A trusted company will gladly share case studies, before-and-after photos, or let you talk to past customers.

Look for experience in projects similar to yours, not just general building work.

Ask to see:

• Before-and-after photos of similar extensions
• Case studies showing how they approached challenges and delivered results
• Customer testimonials or references you see online or speak to directly. 

You want to know they’ve done your type of project before—whether it’s a rear extension, orangery, kitchen knock-through, or full wraparound build. Experience with similar styles, budgets, and planning rules really matters.

A solid track record gives you confidence. You can trust them to keep their promises, tackle surprises, and provide a result you’ll love.

3. Ask About their process

A good company will guide you through planning, design, and construction—not just show up with a hammer. At the outset they will have a clear idea of the type of project that is going to best match your brief. Before you order, make sure you understand what this project involves. 

Ask questions like:

• Will they help with planning permission or drawings?
• Do they provide a detailed schedule and timeline?
• Who will be your main point of contact?

Clarity upfront avoids confusion later.

4. Look for Clear, itemised quotes

A vague quote is a red flag. You want all the quoted works listed so there is no ambiguity about what work is being carried out. 

You should expect a complete quote along with colour 3D CAD drawings. This way, you can see exactly how it looks from every angle. Again, there is no ambiguity.

If something’s unclear—ask. A trustworthy company won’t mind explaining the details.

5. Trust your gut

If communication feels off from the start, or something doesn’t sit right—listen to that feeling. You’ll be working with this team for weeks or months in your home. Trust and communication matter as much as skills.

Bonus Tip: Don’t Choose Based on Price Alone The cheapest quote is rarely the best value. Focus on quality, trust, and a team you feel confident in—not just the bottom line.
