Good to know
Common questions
General guidance about builders in the UK, not specific to any one business.
Do I need planning permission for an extension?
Most single-storey extensions and loft conversions fall under permitted development if they meet size and distance rules. Two-storey extensions, larger projects and some listed buildings need formal permission. Local authority and property type determine the requirement.
What is building regulation approval and why is it needed?
Building regulations ensure work meets safety, structural and environmental standards. All structural work, electrical, plumbing and heating installations must comply. A qualified inspector certifies the work meets standards before sign-off.
How long does a typical extension take?
Single-storey extensions usually take 3–6 months depending on size and complexity. Two-storey work typically takes 6–9 months. Weather, material delays and unforeseen issues can extend timescales.
What happens if problems are found during renovation?
Structural issues, asbestos, rot, or hidden damp are common in older properties. Work must stop until these are assessed and remedied. This adds time and cost but is essential for safety and property value.
Can a loft conversion be added to any roof?
Pitched roofs with good headroom convert well. Flat or low-pitched roofs, skylights only, and properties with trusses instead of beams make conversion difficult or impossible. A surveyor assesses feasibility.
What causes brickwork pointing to fail?
Mortar degrades from weather exposure, salt attack, movement, and poor original work. Hard cement mortar can damage softer bricks. Repointing with matching mortar prevents water damage and keeps walls sound.
