Most enquiries fall into one of two groups. Choose yours to see the services, arranged the way they are usually needed.
Design-stage calculations, pre-completion testing and the evidence building control asks for at sign-off.
Periodic safety checks and certificates for landlords, managing agents and business owners.
Your project
Pick the closest match. Each guide lists the services by stage, so nothing arrives as a surprise at sign-off.
A new home needs energy, water and overheating calculations at design stage, then testing and as-built evidence before building control will sign it off.

Request a quote for this projectIf work went ahead without Building Regulations approval, the local authority may be able to regularise it (for a higher-risk building, the Building Safety Regulator). A registered building control approver cannot accept these applications, approval is not guaranteed, and some opening up or alterations may be needed.

About RegulaBuild
RegulaBuild is your point of contact throughout, taking responsibility for managing the agreed services and delivering the reports and documentation included in your quotation. We read the drawings or the property record, identify what applies, and coordinate the calculations, tests and checks until the evidence is complete. The technical work is carried out by qualified independent specialists, accredited or registered where the law requires it, who issue their reports and certificates under their own name.
Our reports and testing support the compliance process. Approval and completion decisions remain with your building control body.

Before you enquire
Anything else, ask in the quote form or call us.
Yes. Describe the property, the work and anything you have been asked for, such as a condition from building control or a request from a letting agent. We will tell you what applies and set it out in your quotation.
Yes, and it usually saves time. Add every service you think applies; the quotation lists each one with its own scope and price.
No. Early drawings or a short description are enough to start. Some calculations need the final specification before they are issued, and the quotation will say so.
No. Your enquiry is not a booking. Your quotation confirms the payment schedule. Work and appointments are confirmed following acceptance and receipt of any required payment. If a test or deadline is close, say so in the form.
The output named in your quotation, for example a SAP report, a test certificate or an EICR, sent as a PDF. Where building control needs it, we can send it to them directly.
