Building Control Approval & Packages

Building Control does not approve intentions, it approves evidence. We prepare the structural package your submission needs, then answer the officer's questions until it is signed off.

Building Control Approval & Packages

What we cover.

Most structural work on an existing building needs Building Control approval, and most delays happen because the submission is incomplete rather than because the engineering is wrong. We prepare packages written to be read by a building control officer, and we stay with them until approval rather than issuing calculations and disappearing.

In detail

What building control approval & packages actually involves.

What a package contains

A complete package sets out the design loads and where they came from, the members selected, the checks performed, the bearing and connection details, and the standards applied. A number without the working behind it is not evidence, which is why calculations are submitted rather than conclusions. Ours are issued as readable calculations rather than raw software output, so an officer can follow the reasoning without reconstructing it.

Where queries come from

Queries are normal and they are usually about the same things: a beam sized without the padstone checked, an opening formed without considering lateral stability, or foundations left unaddressed where a new column concentrates load that a wall previously spread. We answer them directly rather than passing them back to your builder.

Two systems

Scotland and England work differently. A Scottish building warrant must be granted before work starts and is a formal application with drawings and calculations up front. In England and Wales you can proceed by full plans or by building notice, with different consequences if something is later questioned. We have submitted under both.

Work already done

Where work has already been done without approval, regularisation is usually possible but it needs the existing structure assessing as built rather than as intended. That is a different exercise from designing something new, and it is worth being honest about what can and cannot be evidenced after the fact.

How Lead Group helps

We prepare the full design and drawing package your submission needs, in England, Wales or as a Scottish building warrant, and we stay with it until it is approved. Queries come back to the engineer who did the work, not to a coordinator, and regularisation of work already carried out is assessed as built rather than as intended.

How we work

Why do Building Control submissions get rejected?

Almost always because something is missing rather than because the engineering is wrong. The commonest omissions are the padstone or bearing check under a new beam, the effect of a new opening on lateral stability, and the foundation beneath a new column that concentrates what a wall used to spread. A package that anticipates those three questions usually goes through without a query.

  • Designs checked and signed by a Chartered Structural Engineer
  • Packages written to be read by a building control officer
  • £5m professional indemnity cover
  • Queries answered through to approval, not just issued

Standards & codes

The codes behind building control approval & packages.

Eurocodes 0-9 & UK National Annexes

BS EN 1990 through BS EN 1999 govern the basis of design, actions, and the design of concrete, steel, timber, masonry and aluminium structures. Every calculation we issue references the relevant Eurocode part and its UK National Annex, and states which parts were applied.

Analysis, design & drafting software

Structural analysis and design in Tekla Tedds and Tekla Structural Designer, with Autodesk Robot, CSC Fastrak, CSC Portal Frame, MasterSeries and Hilti Profis used where a scheme suits them. Drawing production in AutoCAD, and modelling in Autodesk Revit where a project is delivered in BIM. Output is issued as readable calculations rather than raw software printouts, so a checker or a building control officer can follow the reasoning.

Approved Document A (Structure)

The Building Regulations requirement your local authority Building Control checks against. Our calculations and drawings are prepared to demonstrate compliance so your submission is accepted without back-and-forth.

Professional indemnity insured

Every report and calculation package is backed by professional indemnity cover, which is what lets a lender, Building Control or another engineer rely on it.

Process

From enquiry to sign-off.

1

Enquiry

Send drawings or describe the problem. We confirm the scope, the deliverables and a target timescale.

2

Information

We agree the survey, drawings or data we need and any site access required.

3

Engineering

Design, calculation or assessment to the relevant Eurocodes and UK National Annex.

4

Issue

A clear, defensible report or set of calculations, with assumptions and limitations stated.

Selected work

Real structures, surveyed and engineered.

Questions

Common questions

Do you deal with Building Control directly?

Yes. We would rather answer the officer's questions ourselves than have them relayed through your builder, which is slower and loses detail.

Can you submit a building warrant in Scotland?

Yes. A warrant must be granted before work starts and needs drawings and calculations up front, which is a different process from the English full plans route. We have submitted under both.

Work has already been done without approval. Can you help?

Usually. Regularisation means assessing the structure as built rather than as designed, and being honest about what can be evidenced after the fact. Sometimes opening up is needed to confirm what is actually there.

Do you work with approved inspectors as well as local authority?

Yes. Both need the same engineering; the difference is administrative, and a package written for an officer works for either.

What do you need to prepare a submission?

Drawings if they exist, or a survey of what is actually there if they do not. For alterations, information about what sits above and below the area being changed is usually the critical piece.
