Over 250 verified reviews across Checkatrade, Google, and Rated People. Every review below was written by a real client after their project completed — not curated, not edited.
A builder's review score tells you one thing. The pattern across hundreds of reviews tells you something far more useful. When you read through TCM's verified reviews, three attributes appear consistently — not occasionally, but in the overwhelming majority of projects across every service type.
The first is communication. Clients describe receiving weekly updates without asking for them, having calls returned promptly, and being told about problems before they became surprises. This is not a soft attribute — it directly determines whether a building project stays on budget and on time.
The second is quote accuracy. Approximately 84% of TCM's reviews mention that the final invoice matched or came in below the original fixed-price quote. In an industry where cost overruns are standard, this is the single most financially significant thing a builder can offer a homeowner.

"TCM built a two-storey rear extension on our Victorian semi. The planning drawings were accurate, the structural engineer was on site throughout, and they finished three days ahead of schedule. The brickwork matches the existing house perfectly — something three other builders said was impossible. We've already recommended them to our neighbours."
"We had a dormer loft conversion done. Constantin visited three times before work started to make sure we understood every stage. The team were tidy, professional, and the new bedroom and en-suite are exactly what we wanted. Building control signed off first time. Worth every penny."
"Full house refurbishment across four bedrooms, two bathrooms, kitchen, and all communal areas. TCM managed every trade — plumbers, electricians, plasterers — so I never had to chase anyone. The project manager sent weekly photo updates. The finish is genuinely high-end. I've used them twice now."
"Converted our double garage into a home office and utility room. The insulation and underfloor heating are brilliant — it's warmer than the main house in winter. They handled the building regs application and we had the completion certificate within two weeks of finishing. Highly recommend."
"Single-storey kitchen extension with bi-fold doors. The quote was itemised and fixed — no extras appeared on the final invoice. The team were on site every day, started at 8am, and cleared up before leaving. The glazing and tiling are exceptional. Our kitchen has doubled in size."
"I manage six rental properties and TCM handle all my maintenance contracts. They respond within four hours for urgent issues and the quality of repair work is consistent across all properties. Having one reliable contractor for everything has saved me a significant amount of time and money."
"New kitchen and two bathrooms fitted simultaneously. They stripped everything out in one day and the project was complete in three weeks. The tiling is immaculate and the kitchen units are perfectly aligned. The plumber and electrician worked around each other without any delays. Really impressive coordination."
"Hip-to-gable loft conversion with a large dormer. TCM handled the party wall agreement with our neighbours, which was a relief as it had caused issues with a previous contractor. The structural steel was installed in one day with no damage to the ceilings below. The room is enormous and the views are incredible."
"Full roof replacement on a 1930s detached house. They matched the original clay tiles exactly and replaced the lead flashing around the chimney stack. The scaffolding was up and down within a week. No leaks, no mess, and they found and fixed a hidden rafter issue that could have caused serious problems."
"Wrap-around extension combining a rear and side return. The design team helped us get the most out of the footprint and the planning application was approved first time. The build took 14 weeks — exactly as quoted. The open-plan kitchen-diner is transformative. We cannot imagine the house without it."
"Office refurbishment across two floors — new suspended ceilings, raised access flooring, partitioning, and full redecoration. TCM worked over two weekends to minimise disruption to our staff. Everything was done to a commercial specification and the project manager kept us updated throughout. We've already booked them for phase two."
"We bought a tired 1970s property and TCM refurbished it completely before we moved in. New wiring, new plumbing, new heating system, plastering throughout, and a full kitchen and bathroom fit-out. They finished two weeks early and the quality throughout is excellent. The fixed price quote gave us real peace of mind."
"Side return extension to create a larger hallway and downstairs WC. A small job by their standards but they treated it with the same attention to detail as a major project. The brickwork is beautiful, the floor tiles are perfectly laid, and the whole thing was done in four weeks. Brilliant from start to finish."
"Velux loft conversion to create a study and storage room. No planning permission required and building regs were handled entirely by TCM. The Velux windows let in far more light than I expected and the insulation is excellent. The staircase fits perfectly into the landing without losing any bedroom space."
"Master en-suite and family bathroom refurbishment. The tiling is flawless — large format porcelain laid perfectly level. The underfloor heating was fitted under both rooms and the plumbing was rerouted without opening the ceilings below. Clean, professional, and exactly on budget."
"Annual maintenance contract covering my home and two investment properties. TCM carry out quarterly inspections and deal with any issues promptly. Having a single point of contact who knows all three properties has been invaluable. Response times are always within the agreed SLA."
"Converted our integral garage into a fourth bedroom with an en-suite. The structural opening into the house was done in a day with no disruption to the rest of the property. The room is warm, well-insulated, and the finish matches the rest of the house. Building control approved without any snags."
"Two-storey side extension adding a bedroom above and a playroom below. TCM were recommended by three separate neighbours who had used them previously. The build quality is outstanding — the walls are perfectly plumb, the windows are sealed correctly, and the roof matches the main house exactly. We would not hesitate to use them again."
"Three builders quoted us for the dormer loft conversion. Two were cheaper. We chose TCM because Constantin took the time to explain exactly what the structural work involved and why certain decisions had to be made in a specific order. That level of knowledge gave us confidence. The result justified every penny of the difference in price. Building control signed off first time, the en-suite is beautiful, and the room has genuinely changed how our family uses the house."
"I've used three different building companies over the years for various projects. TCM are in a different category. The project manager sent me a photo update every Friday without being asked. When a delivery of tiles arrived damaged, they sourced replacements and absorbed the delay without pushing the completion date back. That kind of problem-solving is what separates a good contractor from a great one. The house looks extraordinary."
"We needed the office refurbished without closing for more than two days. TCM planned the entire project around our operations — working evenings and weekends for the structural and noisy work, then completing the fit-out during normal hours. Not a single member of staff complained about disruption. The finished offices look professional and modern, and the project came in exactly on the agreed price. We've already commissioned phase two."
Most homeowners look at a star rating and move on. That approach misses the information that actually predicts whether your project will go well. Here is what to look for when reading reviews for any building contractor.
Volume and recency together. A builder with 200 reviews from five years ago and none from the past 12 months may have changed ownership, lost key staff, or declined in quality. Look for a sustained pattern of recent reviews — at least 20 in the past year.
Specificity over generality. "Great work, highly recommend" tells you nothing. "The brickwork matched the existing house exactly and the structural steel was installed without damaging the ground-floor ceiling" tells you the reviewer understood what good work looks like and observed it being done.
How the contractor handles negative reviews. Every builder with enough reviews will have at least one negative one. What matters is whether the response is defensive or solution-focused. A contractor who acknowledges a problem and explains how it was resolved is demonstrating the same behaviour you want on your project.
Checkatrade contacts homeowners directly before publishing reviews. Google verifies reviewer accounts. Unverified platforms carry higher risk of manipulation.
A builder with 100 reviews for property maintenance and 2 for loft conversions is not necessarily experienced in loft conversions. Filter reviews by the service you need.
Any reputable contractor will provide contact details for previous clients on similar projects. If they refuse, treat that as a significant warning sign.
The pattern in negative reviews is more revealing than the pattern in positive ones. Repeated mentions of the same issue — poor communication, cost overruns, unfinished work — indicate a systemic problem.
A 9.8 on Checkatrade and a 2.1 on Google suggests the contractor may be managing their Checkatrade profile actively while ignoring other channels. Consistent scores across platforms indicate genuine quality.
