Use of This Site
CalcTools.uk provides free online construction calculators for estimation purposes. You may use our calculators freely for personal and commercial projects.
Accuracy Disclaimer
Our calculators provide estimates based on standard UK material sizes and typical construction practices. Results should be used as a guide only. Actual material requirements may vary due to:
- Site conditions and irregularities
- Specific product dimensions that differ from standard sizes
- Skill level and cutting technique
- Waste from damaged or defective materials
- Local building regulations and requirements
Always consult a qualified professional for structural work and ensure compliance with UK Building Regulations. We are not liable for any losses arising from the use of our calculators.
Intellectual Property
The content, design, and code of CalcTools.uk are our intellectual property. You may not reproduce, redistribute, or create derivative works from our calculators without permission.
Affiliate Links
Some calculators include links to retailers such as Wickes, B&Q, Screwfix, Toolstation, and Amazon. These may be affiliate links, meaning we earn a small commission if you make a purchase. This does not affect the price you pay. We only link to reputable UK retailers.
Changes to Terms
We may update these terms from time to time. Continued use of the site after changes constitutes acceptance of the new terms.
