Single Storey Extensions in Slough
What should I look for when hiring a builder for a single storey extension in Slough?

When hiring a builder for a single storey extension in Slough, look for clear scope, fixed-price quoting, proof of insurance, recent references, and a builder who can explain structure and Building Regulations without waffle.
The quote should spell out foundations, drainage changes, brick and blockwork, roof finish, insulation, plastering, and Building Control inspections. For Slough homeowners, clear exclusions and a realistic programme matter because small access problems can quickly become extras.
The strongest hiring test is whether the builder can turn a vague idea into a clear scope before asking you to commit. Look for insurance evidence, references, quote detail, payment stages, Building Control knowledge, and a named person responsible for the site.
Single storey extensions are usually the simplest way to add ground-floor living space, but the roof, drainage, and opening into the house still need proper design. Costs move when foundations deepen, drains cross the footprint, rooflights or lanterns are added, or a wide opening needs heavier steelwork.
Slough projects are often value-led improvements on busy residential streets, including semis, terraces, and practical family homes. Tighter parking, skip placement, and delivery access can affect labour time and should be discussed before the quote is treated as fixed.
Slough sits under Slough Borough Council. Slough Borough Council checks can become more important where parking, overlooking, previous extensions, or dense street layouts are involved.
Before agreeing the work, ask for a written scope that names inclusions, exclusions, payment stages, variation process, site protection, waste removal, and who manages the job day to day. That is the difference between a headline price and a buildable quote.
Planning permission and Building Regulations are separate. Even if planning is simple, Building Control still needs the relevant structure, insulation, drainage, fire safety, ventilation, electrics, roof work, and final completion evidence for the specific single storey extension.
