This guide cuts through the noise. Whether you’re planning a loft conversion in Hackney, a rear extension in Barnet, or a full home refurbishment in Greenwich, here’s everything you need to know before signing a single contract.
Why So Many London Homeowners Get It Wrong
London’s property market moves fast. That pressure leads many homeowners to rush the builder selection process, picking whoever calls back first or whoever quotes the lowest price. Both are mistakes that end up costing more in the long run.
A cheap quote from an unverified builder often signals missing trades, poor materials, or hidden charges that surface mid-project. And once work has started, you have very little leverage to push back.
The good news? Knowing what to look for makes all the difference.
What to Look For in a Construction Company in London
Not all building contractors are built the same. Here are the key things every homeowner should verify before hiring a construction company in London.
1. Accreditation and Verification
Always check that your builder is listed on Checkatrade, Yell.com, or a recognised trade body. These platforms verify the business, check insurance, and collect genuine homeowner reviews. A builder who is reluctant to share their Checkatrade profile is a builder worth avoiding.
At MBT Group, we are fully verified on Checkatrade and Yell.com, with Gas Safe registered tradespeople and appropriately certified electricians working on every relevant project.
2. Experience Across Multiple Trades
A strong construction company in London should be capable of coordinating every trade your project needs — not just the headline work. That means having direct relationships with architects, structural engineers, carpenters, plumbers, electricians, and decorators.
Single-trade builders may be excellent at their specialty but often struggle to manage the wider project. You end up doing the coordination yourself, which is stressful and frequently leads to delays.
MBT Group has over 35 years of combined experience across all trades, giving our clients a single point of contact from start to finish.
3. Transparent Quoting
A professional building contractor provides a detailed, itemised quote — not a one-line number scribbled on a piece of paper. You should be able to see exactly what you are paying for: labour, materials, waste disposal, and project management.
If a builder cannot explain their quote line by line, that is a red flag.
4. References and a Real Portfolio
Ask for references from recent London projects and, wherever possible, ask to visit a completed job. Photos on a website are a start, but speaking to a real homeowner who has been through the same process gives you genuine insight into how a builder operates under pressure.
The Most Popular Home Construction Projects in London Right Now
London homeowners are investing in their properties more than ever. With property prices high and moving costs even higher, extending or renovating your existing home delivers far better value than upsizing. Here are the projects generating the most demand across the capital in 2026.
Loft Conversions
A loft conversion remains one of the highest-return investments a London homeowner can make. Adding a bedroom and ensuite in the roof space typically costs between £40,000 and £70,000 and can add 20% or more to your property’s value. Dormer and mansard conversions are particularly popular across inner London boroughs.
Rear and Side House Extensions
Ground-floor extensions that open up the kitchen and living space are consistently among the most requested projects. An open-plan kitchen-diner with bifold doors onto the garden has become the standard aspiration for London families. A well-planned single-storey rear extension can be completed in 10 to 14 weeks.
Basement Conversions
For properties in prime London postcodes where space above ground is limited, basement conversions unlock significant square footage. They require specialist structural knowledge and careful planning, which is why choosing an experienced construction company in London is critical for these projects.
Full Home Refurbishments
Buying a run-down London property and fully refurbishing it is a smart strategy — if you have the right builder. A complete home refurbishment project typically covers structural repairs, re-roofing, rewiring, plumbing upgrades, kitchen and bathroom installation, plastering, and full redecoration. MBT Group manages all of this under one roof.
