What a building regulations application involves

This service suits every two-storey extension, because each one needs building regulations approval 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.

Towns in Clwyd include Wrexham (LL13), Buckley (CH7), Deeside (CH5), Colwyn Bay (LL28), Flint (CH6) and Rhyl (LL18). If yours isn't listed, we still cover it.

Fees

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

Rules in Wales

In Wales, building regulations approval follows the Welsh Approved Documents, which differ from England's in places, notably Part L for energy efficiency. Approval comes from the council's building control service or a registered approver. The structure, fire, ventilation and drainage checks are broadly similar, with a completion certificate at the end.

Approval in Wales: Householder planning application: £585. Councils normally decide householder applications within 8 weeks.

Building regulations: Building regulations approval under the Welsh Approved Documents, which differ from England's in places (notably energy efficiency).

The Party Wall etc. Act 1996 applies in Wales, so notices may be needed for work on or near a shared wall or boundary.

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 control then inspects key stages, such as foundations, damp-proofing, drainage and insulation, before issuing the completion certificate.
