Sovereign Facade Engineering Consultants Ltd answers common questions about facade engineering below, covering what a facade engineer does, how engagements work, costs and timelines, and key compliance areas including the Building Safety Act and Gateway 2.
Facade engineering is usually priced per project rather than by an hourly rate. The cost depends on the scope: a single structural calculation package for a balustrade is a modest fixed fee, while full facade engineering design for a building is priced according to the system, scale, and deliverables. Sovereign provides a fixed fee for every engagement before any work begins, so there are no open-ended costs.
Timescales depend on scope. Standalone calculation packages or shop drawings for a defined element can often be turned around in days to a couple of weeks; full facade design for a building runs alongside the project programme. We confirm a timeline with the fixed fee at the outset and provide progress updates at defined stages.
Yes. Sovereign provides facade engineering services to architects, contractors, and developers throughout the United Kingdom. Most facade engineering work, including design, calculations, thermal modelling, and shop drawings, is delivered remotely with deliverables issued electronically, so we support projects nationwide.
Yes. We regularly act as additional capacity for specialist facade contractors and drawing offices that are at capacity, producing shop drawings and calculations to the contractor's house style and standards under engineering oversight. We can scale support to your programme.
You deal directly with the engineering team doing the work, through a single named point of contact for your project. There are no account-management layers between you and the people producing your facade engineering.
A facade engineering consultant provides the technical design, analysis, and documentation for a building's external envelope. This includes selecting and designing the facade system, calculating structural loads on glazing and framing, assessing thermal and fire performance, and producing the calculations, specifications, and shop drawings needed to build and gain approval for the facade. In the UK this work is carried out to Eurocode structural standards, CWCT guidance, and the Building Regulations.
Sovereign works to current UK and European standards: the Eurocodes (including EN 1990 and EN 1991 for loading and EN 1999 for aluminium), the CWCT Standard for Systemised Building Envelopes, the relevant British and European product standards such as BS EN 13830 for curtain walling and BS EN 16612 for glass, and the UK Building Regulations including Approved Documents B (fire) and L (energy).
The Building Safety Act 2022 introduced a stricter regulatory regime for higher-risk buildings in England, defined as buildings over 18 metres or at least seven storeys. These buildings require Gateway 2 approval from the Building Safety Regulator before construction can begin, and the facade is a central part of that scrutiny. Facade fire performance, compartmentation, and structural adequacy must be evidenced. Sovereign produces the facade engineering documentation that supports a Gateway 2 submission.
No. Gateway 2 approval rests solely with the Building Safety Regulator. Sovereign produces the facade engineering design, calculations, and documentation that support a client's Gateway 2 submission; it does not grant or own the approval itself. This is an important distinction: we provide the engineering evidence, and the Regulator makes the decision.
An architect leads the overall design intent and aesthetics of a building. A facade engineer provides the technical engineering behind the external envelope: calculating loads on the facade, specifying and designing the system, assessing thermal and fire performance, and producing fabrication and compliance documentation. The two work together to turn design intent into a facade that is buildable, compliant, and able to perform.
Yes. Sovereign is independent of any facade system manufacturer or installer. When we advise on a system or review a specification, the recommendation reflects the engineering needs of the project rather than any commercial interest in a particular product. For clients seeking an impartial second opinion, this independence is central to the value we provide.
Yes. Sovereign Facade Engineering Consultants Ltd carries professional indemnity insurance with an A-rated insurer and is a UK-registered company (Companies House No. 17193274, registered in England and Wales). We operate under a single point of accountability for all client engagements.
