Selecting the right SIP contractor is vital for a successful, high-quality project. Look for transparency in scope, certified materials, and strong warranties to ensure industry standards and long-term protection.
A trustworthy contractor aligns with your goals, offers expertise, and ensures a smooth, efficient construction process.
The first questions people often ask is
How much is it and
When can you get to site. And while they are valid questions they don't really mean much without context and content. At McVeigh Offsite we would encourage you to explore the context and quotation content to ensure the SIP Contractor you engage with are offering the level of service you're expecting.
A few considerations and questions you may ask during your deliberations:
Scope of Works/Inclusions and exclusions
Ensure the quotation includes a detailed description of what is included and excluded, such as structural designs, internal walls, beams, delivery, and cranes.
Each
SIP home quotation should have a scope of works with a detailed description of what's included and what's excluded from a project tender. Common exclusions by some providers are Structural Designs, non-load bearing internal walls, structural beams (or provisional sums for structure that can change), delivery, and cranes.
At McVeigh Offsite, our quotes clearly define what's included and excluded — no hidden surprises.
SIPs System Certification
Verify that the SIP builder is certified with a British Agrément Certificate (BBA) and has undergone rigorous testing.
There are lots of SIP providers online offering products into the UK construction market that aren't suitably certified. Our advice is to ensure the SIP system you are choosing has been vigorously tested and has at least a current British Agrément Certificate (BBA).
At McVeigh Offsite we are a Kingspan Tek delivery partner and can issue to you the BBA Certificate, specification manual, standard details, certified thermal calculations, etc.
Product Range
Confirm the SIP contractor offers suitable panel options and complementary products, such as beams and roof joists, for your project.
Ensuring your SIP provider is offering the best product range for your project is essential. At McVeigh Offsite we offer the Kingspan 142mm and 172mm thick SIPs. The different panels are selected for thermal, structural, or best project fit. We also offer a full range of Glulam beams, steel beams, and engineered roof joists.

Warranty and Professional Insurance
Check that the provider offers product warranties and holds appropriate insurances, including Professional Indemnity.
Ensure your SIP provider can offer a product warranty and suitable insurances.
We can offer the Kingspan Tek Product Warranty and hold the relevant insurances including Professional Indemnity.
Structural Timber Association (STA) members
Look for membership in the Structural Timber Association (STA) and adherence to quality standards like STA Assure Gold. The STA provides members with support and technical guidance on all things timber, keeping abreast of any changes in legislation.
At McVeigh we are STA members and hold the Gold standard of STA Assure.
Supply and Install
Opt for contractors offering both supply and installation services to ensure seamless coordination, site inspections, and warranty validation.
Splitting the packages of supply and installation can be problematic when it comes to coordination, construction phase site inspections, and final quality assurance handovers. It can also invalidate warranties and guarantees.
At McVeigh Offsite, workshop/site coordination and inspections are fundamental for a successful outcome, and we strongly advocate this approach.
Qualified and Certified
Ensure the contractor has a well-qualified team with relevant certifications and site operation expertise. At McVeigh Offsite we have a blended team with qualifications from BSc (Hons) to City and Guilds Crafts. We have in-house Appointed Person, CSCS, and Slinger Signallers for site operations.
Testimonials and Reviews
Review past customer experiences to gauge the contractor's reliability and values.
It's always good to hear about different people's experiences. We all have different values and expectations but reviews can be a good indication of past performance.
McVeigh Offsite has some great reviews and testimonials online and on our website that offer an insight into our values.
