Common questions

General guidance about builders in the UK, not specific to any one business.

What is building regulation approval and why is it needed?

Building regulations ensure structures are safe, energy-efficient and comply with UK law. Inspectors check foundations, structural work, electrics, plumbing, insulation and fire safety. Most extensions, loft conversions and renovations need approval. Failure to obtain it can cause problems when selling.

Do I need planning permission for a loft conversion?

Most loft conversions are permitted development and do not need planning permission if the roof line is not raised and dormers are modest. Listed buildings, conservation areas and some terraces have stricter rules. A surveyor can confirm what applies to your property.

How long does an extension typically take to build?

A single-storey extension usually takes three to six months depending on size, weather and complexity. Double-storey work takes longer. Delays occur if unforeseen problems arise, such as poor ground conditions or structural issues discovered during work.

What causes brickwork to fail and need repointing?

Mortar weathers over time, allowing water into joints and behind bricks. Frost and salt damage accelerate this. Poor original mortar, rising damp and structural movement also cause failure. Repointing prevents water ingress and further decay.

What should I budget for contingency on a renovation?

Industry practice suggests setting aside ten to twenty percent of the total budget for unexpected costs. Older properties often hide issues—rotten timbers, asbestos, poor electrics or plumbing—that only appear once work begins and costs rise.

When do groundworks need specialist testing or surveys?

Sites with poor drainage, clay soils, or near water courses should have soil and drainage surveys. Contaminated land requires testing. Buildings near trees need root assessment. Utility locations must be confirmed before excavation begins.
