1. Mace Group Ltd
Address: 155 Moorgate
Contact: +44 20 3522 3000
Mail: [email protected]
Business hours: Monday to Friday, 9AM – 5:30PM
This London-based consultancy has played a pivotal role in shaping some of the city’s most iconic landmarks, including The Shard, the London Eye, and Tottenham Stadium.
What sets them apart isn’t just their portfolio. It’s how they approach complex projects with a blend of precision and creativity.
Clients often praise their ability to manage large-scale developments without losing sight of the finer details.
Their collaborative way of working tends to attract long-term partnerships, especially with clients seeking both innovation and reliability. However, some critics mention that their layered approval processes can occasionally slow down decision-making on fast-moving projects.
Still, with nearly £2 billion in annual revenue and a track record of delivering standout results, they continue to raise the bar across the industry.
Their influence is hard to overlook, particularly in projects that demand both scale and a forward-thinking mindset.

2. Ardmore Group
Address: 6, Wharf Studios, 28 Wharf Rd
Contact: +44 20 8344 0300
Business hours: Monday to Friday, 8:30AM to 5PM
Ardmore Group has carved out a distinctive space in London’s construction scene, particularly in the high-end residential and mixed-use market.
They handled £349 million across five major London projects recently, with their order value surging by an impressive 165 percent—largely thanks to a wave of premium city schemes.
Their projects tend to focus on striking, upscale designs, and they are often trusted with schemes that demand a high level of detail and craftsmanship.
That said, some industry insiders note that their heavy emphasis on luxury projects can limit their versatility across other sectors. There’s also the occasional mention of longer construction timelines on more intricate developments.
Still, Ardmore’s ability to deliver complex, high-spec builds has kept them firmly in the spotlight. They have a clear knack for blending scale with design flair, which continues to earn them a seat at the table for some of London’s most exclusive projects.
Organized
“I have visited several Armmore Construction projects, and I was incredibly impressed by how well organised the sites were, both in terms of layout and staffing. The standards were exceptionally high, but what truly stood out was the precision, quality control, and meticulous record keeping that ensured top tier results. Throughout my visits, I had the opportunity to work with a range of staff, from groundworkers to directors, and I found everyone friendly, helpful, and highly knowledgeable. It was a pleasure to see such expertise and commitment in action.”
- Matthew Jones Photography, Google Review
Well managed
“Site is well managed, security is well managed, generally a good site to work on, providing you are not subcontracted to CB decorators who don’t care about you, otherwise Ardmore is a good firm to work for.”

3. Hill Group
Address: Gunpowder Mill, The Power House, Powdermill Ln, Waltham Abbey
Contact: +44 20 8527 1400
Mail: [email protected]
Business hours: Monday to Friday, 9AM – 5:30PM
Hill Group tends to fly a little under the radar, but their numbers speak loudly. Ranked sixth in London by project value, they completed £479 million across 10 projects in 2024 alone.
Their strength lies in solid civil engineering and large-scale public works, with a steady hand in residential and regeneration schemes too. They’ve built a reputation for dependable delivery, often handling complex infrastructure projects that others might shy away from.
One recurring theme among industry insiders is their practical, no-fuss approach focused more on results than flashy marketing.
That pragmatism is a double-edged sword, though. While their consistency earns respect, some observers feel they occasionally play it too safe, sticking to tried-and-true methods rather than pushing design boundaries.
Still, their impact is clear, particularly in projects that demand technical know-how and reliable track record. There is a quiet confidence in how they work, and it shows.
Quality service
“We were looking for a family home near the station with plenty of room for our teenagers and we found the perfect home with Hill in Cambridge. Our house has 4 floors, loads of storage, quality kitchen and bathrooms, and underfloor heating. The space is very well designed, and the garden is private. We couldn’t be happier with the quality of our home and the service from Hill.”

Great standard
“Very happy in our new home, great standard and aftercare service.”

4. Bell Decorating Group Ltd
Address: GF Building 2, quinton business park, Quinton, Birmingham
Contact: +44 12 1326 0934
Mail: [email protected]
Business hours: Monday to Friday, 8:30 AM – 5PM
Bell Decorating Group Ltd has quietly built a strong reputation through its niche expertise in décor and interior finishing. Their recent £125 million London refurbishment highlights just how much influence they wield in shaping the final look and feel of major city buildings.
They’re often the name behind the polished interiors of high-profile commercial spaces, and their work tends to blend traditional craftsmanship with modern appeal.
What stands out most is their attention to fine details—something that consistently earns praise from architects and developers alike.
However, their specialized focus means they are not typically involved in structural work or large-scale construction, which can limit their role in broader projects.
Still, their ability to elevate interiors with precision and flair makes them a trusted choice for projects aiming to impress once the scaffolding comes down. Their work often speaks louder than their name, and that’s exactly how they like it.

5. BAM Construct UK
Address: Unit 4, CityPoint, 1 Ropemaker St
Contact: +44 20 7374 3600
Business hours: Monday to Friday, 8AM to 5PM
BAM Construct UK tends to stand out in London’s crowded construction scene, not just for its size but for how it weaves sustainability into nearly every project.
Known for high-profile commercial and public sector developments, they’re often the go-to for companies seeking greener, more future-proofed workspaces.
Their office fit-outs and refurbishments, in particular, have gained attention for blending smart technologies with low-carbon materials. This approach feels less like a trend and more like part of their core identity.
Clients value their technical precision and proactive project management, though some mention that their strong focus on sustainability can sometimes bring higher upfront costs.
Still, their consistent delivery across sectors keeps them on the radar for firms prioritizing long-term efficiency. BAM’s reputation for combining scale with sustainability makes them one of London’s more forward-thinking builders.
Quality
“Did the Signing, Lighting and Guarding course. Was given a lot of helpful information that I can apply to my job such as how to set up safely and correctly. The instructor Andi Lewington was very knowledgeable and patient and didn’t mind going over points more than once until the whole group understood and was ready to move on. Also encouraged a lot of group interaction and made the course fun.”
