Andrew Calder

Andrew Calder is a construction professional and technical author with over twenty years of experience in UK building regulations, energy assessment, and heritage property compliance. His career has spanned domestic and commercial construction, listed building consent, conservation area planning, and the practical realities of owning, maintaining, and improving historic properties within the regulatory frameworks that govern them. He writes for property owners, not for professionals. His books translate the dense, often contradictory world of building regulations, planning restrictions, and conservation requirements into plain language that a homeowner can actually use. No jargon. No assumptions. No unnecessary complexity. Calder's approach is rooted in the belief that the people who live in these buildings deserve the same quality of technical guidance that professionals charge hundreds of pounds per hour to provide. A listed building owner facing a repair, an alteration, or a planning application should be able to understand their obligations, their options, and their rights without hiring a consultant to explain the consultant's report. He has particular expertise in Part L compliance, energy performance assessment, SAP and SBEM methodology, CDM regulations, and the specific challenges of applying modern building standards to pre-twentieth-century structures, where the regulations and the building rarely agree with each other. Calder lives in rural France, where he continues to write about construction, property, and the endless puzzle of making old buildings meet new rules.
