Andun vs Temporary Works Consulting: Comparing Specialist TW Design Services

If you're searching for Andun temporary works support and weighing up your options, you're probably a Contracts Manager or Site Agent with a live project, a design gap, and very little time. This article gives you a direct, honest comparison between Andun Engineering Consultants and Temporary Works Consulting & Design Ltd so you can make a fast, informed call about which firm fits your project.

Both are UK-based specialist consultancies. Both cover temporary works design and BS 5975 compliance. But they're built for different clients, different project scales, and different working relationships — and those differences matter when your programme is tight and your CDM 2015 obligations are real.

What Andun Engineering Consultants Does

Andun was founded in 1990 and operates from offices in Chelmsford, Manchester, and Essex with a team of around 15 staff. They're a well-established name in the sector, holding Temporary Works Forum membership and offering Cat III independent checking alongside 3D structural modelling.

Their portfolio skews toward large infrastructure and demolition projects. If your scheme involves complex demolition sequencing, major civils infrastructure, or a client requiring Cat III independent check certification from a named practice, Andun has the track record and technical depth for that work.

What Andun doesn't appear to offer — based on publicly available information — is a weekly retainer for ongoing contractor support or direct WhatsApp access to a qualified engineer for time-critical site queries. Their engagement model follows the conventional consultancy pattern: scope, quote, deliver.

For Tier 1 mega-projects or large demolition contracts, that works well. For SME contractors and specialist subcontractors managing multiple smaller sites, it can create friction.

What Temporary Works Consulting & Design Ltd Does

Temporary Works Consulting & Design Ltd is a remote-first boutique consultancy built specifically around the needs of UK contractors who need fast, complete, BS 5975:2024-aligned temporary works design — without the overhead of a large practice.

The firm operates as a single point of contact for the entire design process. One engagement covers the brief, calculations, sketches, drawings, design risk assessment, RAMS and ITP reviews, permit support, and an issue-ready design pack. You're not managing multiple specialists or chasing sign-off across departments.

Structures covered include excavation support, propping, needling, working platforms, piling mats, falsework, formwork, hoardings, and scaffold interfaces. Working platform and piling mat assessments are referenced to BR 470. Design checking support spans Cat 0 through Cat 3 coordination.

The founder holds MSc CEng MICE credentials with 26-plus years of site-side construction experience. The person producing your design has worked on the type of sites you're managing.

Project Scale and Fit

This is the most practical question when choosing between the two.

Andun suits projects where the client or principal contractor requires a named Cat III independent checking practice with a long track record in infrastructure or demolition. Major demolition sequences, large-span falsework schemes on civils contracts, or structures where Cat III checking is a contractual requirement — that's where Andun's credentials and team size are relevant.

Temporary Works Consulting is built for the contractor who needs complete, compliant, issue-ready design support at a pace that matches the site programme. A groundworks subcontractor mobilising on a new excavation. A structural contractor setting up propping or needling. A civils contractor needing a working platform assessment before piling starts. A site team facing a BS 5975:2024 audit with gaps in their documentation.

The weekly retainer model is particularly relevant for contractors managing several sites or a rolling programme of smaller contracts. It gives you predictable engineering support without the cost and commitment of in-house headcount — and no competitor in the sector currently offers this model publicly.

BS 5975:2024 Compliance: Where Both Firms Stand

BS 5975:2024 is the current UK code of practice for temporary works procedures. In February 2025, it was formally split into BS 5975-1:2024 (procedures and management) and BS 5975-2 (design). Both documents are now in force, and principal contractors are increasingly requiring evidence of compliance before site activities begin.

Andun has been operating in the sector since before the original BS 5975 was published, so their familiarity with the standard isn't in question.

Temporary Works Consulting is explicitly aligned to both parts of the 2025 split. Every design package includes calculations, drawings, and a design risk assessment structured to satisfy BS 5975:2024 and CDM 2015. If your trigger for seeking a consultant is an imminent audit, a client compliance demand, or a gap in your procedural documentation, that alignment matters.

Speed and Access

For site teams, turnaround time and direct access to a qualified engineer often matter more than anything else. A design that arrives three weeks after you needed it isn't useful.

Temporary Works Consulting delivers remotely, so work can begin without a site visit. Remote site safety audits are conducted via structured mobile-phone walk-rounds reviewed remotely, keeping the process moving. Direct WhatsApp access means you can ask a question, request a quote, or flag an urgent site issue without going through a call-handling process.

Andun operates from three physical offices and works on larger, longer-duration projects — their process is built for that scale. For a contractor who needs a design pack within days rather than weeks, the boutique remote model has a clear structural advantage.

Training and Coordinator Support

This is one area where the two firms don't overlap at all.

Temporary Works Consulting offers one-to-one tutoring and mentoring for temporary works coordinators and supervisors, including personal tutoring on live projects and practice exam preparation for CITB-aligned qualifications. If you have a newly appointed TWC who needs to build competence quickly, or a supervisor preparing for a formal assessment, this service is directly relevant.

Andun shows no evidence of offering this type of support. Their model is consultancy delivery, not individual practitioner development.

Tools and Self-Service Options

Temporary Works Consulting provides a free web-based TW Toolbox, available publicly, and an online shop where contractors can purchase standard designs directly. Both are useful for straightforward, repeatable situations where a bespoke design isn't required.

Neither has a visible equivalent from Andun.

Which Firm Should You Choose?

The honest answer depends on your project type, your programme, and what your client or principal contractor actually requires.

Choose Andun if your project is a large infrastructure or demolition scheme, your client specification requires a named Cat III independent checking practice, and you have the programme time to work through a conventional consultancy engagement.

Choose Temporary Works Consulting if you're a UK contractor or specialist subcontractor with active CDM 2015 obligations, a tight programme, and a need for complete, BS 5975:2024-aligned design support delivered quickly. The single point of contact model, the weekly retainer option, and direct WhatsApp access are built for exactly the scenario most SME contractors face when a project mobilises.

If you want a fixed-price quote with no ambiguity about scope or cost, that's what Temporary Works Consulting provides. Request one via the website or WhatsApp — the price is agreed before any work begins.

FAQs

Does Andun offer a weekly retainer for ongoing temporary works support?
Based on publicly available information, no. Their engagement model is oriented toward project-by-project delivery on large infrastructure and demolition schemes.

What's the difference between Cat III independent checking and independent-style check coordination?
Cat III independent checking involves a formal independent check by a separate designer as defined in BS 5975 — this is what firms like Andun offer. Temporary Works Consulting offers independent-style check coordination, which supports the checking process within the design package but is not the same as a named Cat III check from a standalone practice.

Can Temporary Works Consulting handle the same types of structures as Andun?
The two firms cover different parts of the temporary works spectrum. Temporary Works Consulting covers excavation support, propping, needling, working platforms, piling mats, falsework, formwork, hoardings, and scaffold interfaces — the majority of routine contractor needs. Andun has a stronger track record in large demolition and major infrastructure.

How quickly can Temporary Works Consulting start work on a design?
Work can begin without a site visit. Turnaround depends on design complexity, but the remote-first model is specifically built for contractors who need fast delivery. Contact via WhatsApp or the quote form to discuss your programme.

Does Temporary Works Consulting offer BS 5975:2024 compliance support?
Yes. Every design package is aligned to BS 5975:2024, including the February 2025 split into BS 5975-1:2024 and BS 5975-2, and to CDM 2015. Design packs include calculations, drawings, and a design risk assessment structured to meet both requirements.

Can I get a fixed price before committing to any work?
Yes. All quotes are fixed price and agreed upfront — no open-ended billing. Request a quote via the website or WhatsApp.

Does Temporary Works Consulting offer training for temporary works coordinators?
Yes. One-to-one tutoring and mentoring for TWCs and supervisors, including support on live projects and practice exam preparation for CITB-aligned qualifications. This is not a service Andun appears to offer.

Conclusion

Both Andun and Temporary Works Consulting are legitimate specialist firms with real credentials. The right choice comes down to project scale and what you actually need from a consultant right now.

If your project is a large infrastructure or demolition scheme with formal Cat III checking requirements, Andun's track record and team size are relevant. If you're a UK contractor or subcontractor with active temporary works obligations, a tight programme, and a need for complete, compliant design support at a pace that matches your site, Temporary Works Consulting is built for that scenario.

Request a fixed-price quote, confirm the scope, and get your design pack moving.
