Construction
From new builds and extensions to conversions, refurbishments, kitchens, bathrooms and roofing.
Refurbishments
Breathe new life into your property with a full or partial refurbishment. From single rooms to whole-house renovations, we handle every trade under one roof, delivering a smoother, better-coordinated project from start to finish.
Basement Conversions
Unlock the full potential of your property by converting an unused basement or cellar into a bright, functional living space. From home cinemas and gyms to self-contained annexes, we manage every stage of the conversion, including waterproofing, structural work, and finishing.
Loft Conversions
Transform unused roof space into a stunning new bedroom, bathroom, or home office. From dormer and hip-to-gable conversions to full Velux installations, we handle every stage — design, planning, and build — to add real space and value to your home.
extensions
We design-manage and build extensions that add genuine value and connect seamlessly with your existing home from single-storey rear extensions to full wrap-arounds with one team responsible for the whole job.
New Builds
From groundworks and structural build to first and second fix, finishes and handover, BSL Construction manages every stage of your new build under a single experienced team — so nothing falls between trades and nothing gets lost in translation.
Kitchens
A new kitchen touches every trade in the house — building, plumbing, electrics, gas, plastering, tiling and decorating. We handle all of it under one accountable team, so the units, the worktops and the services all line up and the room is finished properly.
Bathrooms
A bathroom is one of the most trade-heavy rooms in a home — plumbing, electrics, tanking, tiling, plastering, ventilation and decoration all in a small, wet space. We handle every part of it under one accountable team, so it's watertight, level and finished to a high standard.
Roofing
New roofs, re-roofs, flat roofs and repairs — carried out by our own roofers with the scaffolding, guttering, leadwork, insulation and making-good handled by the same team. Left watertight, cleared down, and backed by a workmanship guarantee.
Mechanical & Electrical
Complete mechanical and electrical services covering plumbing, heating, gas, air conditioning and electrical systems.
Plumbing
From a dripping tap to a full first-fix, our qualified plumbers and Gas Safe registered engineers handle domestic and commercial plumbing under one accountable team — installed to water regulations, pressure-tested, and backed by a 12-month workmanship guarantee.
Heating
Boiler installations and replacements, heat pumps, full central heating systems, radiators, underfloor heating, servicing and repairs — carried out by Gas Safe registered engineers, commissioned properly, and backed by a workmanship guarantee.
Air Conditioning
Design, supply and installation of air conditioning and ventilation for homes, offices, retail and server rooms — F-Gas registered, cleanly installed, and maintained.
Electrical
Rewires, consumer units, additional circuits, lighting, EV chargers, testing and fault-finding — carried out by qualified electricians and certified to BS 7671, with the Building Regulations notification handled for you.
Water Regulations
Advice, installation and remedial work to meet the Water Supply (Water Fittings) Regulations 1999 — backflow protection, correct fittings and materials, and the paperwork your water supplier expects.
RPZ Testing
Installation, commissioning and annual testing of RPZ (reduced pressure zone) backflow prevention valves — carried out by an accredited tester, with certificates and reminders so compliance never lapses.
Commercial
Reliable maintenance and facilities support for hotels, commercial properties and managed buildings.
Hotel Maintenance
Building, mechanical and electrical maintenance for hotels and serviced accommodation — guest-room repairs, plant and MEP upkeep, compliance and refurbishment works, all from one accountable team that works around occupancy.
Commercial Maintenance
Building, mechanical and electrical maintenance for offices, retail, industrial units and managed properties — one contract, one contact, and every trade in-house.
Planned Maintenance
Scheduled inspection, servicing and testing that keeps buildings compliant and plant reliable — a clear PPM calendar, asset register and reporting, delivered by one in-house team.
Reactive Maintenance
When something breaks, one call gets it fixed — building, plumbing, electrical, heating and drainage callouts with agreed response times and every trade in-house.
Facilities Support
Hard-FM support for facilities and property teams — a single trade partner for maintenance, compliance, minor works and fit-out changes, with reporting that fits how you already work.
