What customers say

Based on genuine customer reviews

BNS Groundwork London has built a reputation across the Fulham area for handling the heavy, technical side of construction, with reviewers repeatedly highlighting foundation and basement groundwork as the company's core strength. Various customers describe excavation, preparation, concrete pours and drainage work being carried out properly, with trenches dug to specification and levels checked before bricklayers arrived. The team is frequently praised for keeping sites tidy while properties remained occupied.

Reviewers mention that tricky ground conditions, including old clay and unexpected rubble, were dealt with by adjusting the design on site to keep the programme moving. Punctuality and organisation come up often, with one customer noting the concrete deliveries were coordinated so work flowed without interruption. Communication is another recurring theme, from a same-day quote and a foreman who answered the phone to a site visit arranged quickly and a firm price that did not change. Customers also value the range of services, from drainage runs and soakaways to steel beams supporting floors above, and a basement conversion that required careful sequencing.

Had a drainage issue under the side return that kept flooding after heavy rain. BNS came out, dug it up properly and rebuilt the run with a new soakaway. Found them after asking around in Fulham for someone who actually does groundworks rather than just patching. No more standing water since.

Had BNS do the groundworks and foundations for a side and rear extension on our house. The dig was bigger than we expected once they got underneath because the existing footings were shallow, but they sorted out an underpin section and got the new pad foundations in without it turning into a mess. The concrete pour was clean, levels were spot on when the bricklayers came in after them. They also fabricated a steel frame for the opening where the old back wall was coming out, delivered and installed it themselves rather than us having to find a separate steel contractor. Drainage was rerouted to the new layout, all properly tied into the existing run. Site was kept tidy throughout, skips swapped over when needed without me having to chase. Solid bit of work and the price held to what was quoted.

started looking into this project late last year and honestly had no idea how much goes into groundworks until we got into it. BNS came out for a site visit pretty quick after we reached out, measured everything up and sent over a proper quote within the week. once we agreed they got the dig scheduled and had a team on site within two weeks. the foundation pour was done over a couple days and they coordinated the concrete deliveries so nothing was sitting around waiting. comms were good throughout, the foreman would ring us if anything came up rather than just making decisions without checking. finished up right around when they said they would which was a relief because we had trades lined up after them

Got quotes from a few places, these lot came back quickest with an actual breakdown not just a number. groundworks started on time and they kept us posted through each stage. solid from start to end

Had them do the foundation and basement groundwork and that really where they seem strongest the dig out prep concrete work and all the heavy parts were handled properly and kept on track not much fluff just steady work and things done in the right order so the next stage could start

Needed groundwork done before the rest of our build could move and these lot kept it moving without making it a mess. They were clear about what needed doing and what could wait. We're near Hammersmith and they seemed very used to this kind of job. solid work, no messing about, and the site felt organised the whole time.
