What a building warrant application involves

This service suits every two-storey extension, because each one needs a building warrant wherever you live in the UK. You get technical drawings and a specification coordinated with the structural engineer, a full plans application, site inspections arranged at each stage, and the completion certificate you will need when you sell. We manage the process, and the work is carried out by vetted teams working under S&K.

Across Lanarkshire we cover East Kilbride (G74), Hamilton (ML3), Cumbernauld (G67), Coatbridge (ML5), Airdrie (ML6) and Motherwell (ML1), plus the smaller places around them.

Fees

Technical drawings and specification are a guide of £1,500–£4,000. The council's building warrant fee depends on the value of the work; we confirm every fee in writing before the design stage starts.

Rules in Scotland

In Scotland, you need a building warrant from the council's building standards service before work starts, assessed against the Scottish Building Standards Technical Handbooks rather than Approved Documents. At the end you submit a completion certificate, which the council accepts after its checks. No work should start until the warrant is granted.

Approval in Scotland: Householder planning application: £371. Councils have two months to decide a local planning application.

Building standards: A building warrant from the council's building standards service before work starts, and a completion certificate at the end. Scotland uses its own Technical Handbooks.

There is no Party Wall Act in Scotland. Shared walls and boundaries are governed by title deeds and common law, so we speak to neighbours early and record the condition of shared structures.

Getting the design right

Full plans and inspections

Full plans approval checks the design before work starts, which we recommend for two-storey extensions. Building standards then inspects key stages, such as foundations, damp-proofing, drainage and insulation, before issuing the completion certificate.

Building regulations for two-storey extensions in Lanarkshire: questions

What is a build-over agreement?

A build-over agreement is permission from your water company to build over or near a public sewer. Many rear extensions sit near shared drains, and the water company will want access protected and the pipe checked. We check sewer records early so the agreement does not delay the start.

Is a building notice or full plans better for a two-storey extension?

Full plans is better for most two-storey extensions. The design is checked and approved before work starts, so problems with structure or fire escape are found on paper rather than on site. A building notice relies on inspections during the build and suits only simple work. Scotland always needs a building warrant.

Do I need building standards if I have planning permission?

Yes. Planning permission and building standards are separate. Planning covers what the extension looks like and how it affects neighbours; building standards cover how it is built and whether it is safe, warm and healthy. A two-storey extension needs both, unless permitted development replaces the planning part.
