S3 Developments Case Study

Long-standing member of the Federation of Master Builders, S3 Developments Ltd, approached us with an application for a 10-year structural warranty on their latest project – a 7 bedroomed executive property in the much-sought-after area of Mere, Cheshire.

Having worked alongside S3 Developments Ltd on 13 previous properties, including a mix of barn conversions and new build construction, we were well equipped to provide a competitive quote for the cover the client needed.

It was clear that the design of the building needed to lend itself to the surrounding properties and was quite complex. In an ever-changing climate within the insurance marketplace, we needed to provide affordable cover, an easy-to-understand policy and conduct regular site inspections to confirm works were being carried out in line with the design, as well as current standards and regulations.

The Project

We were provided with all the necessary design details and ground investigation reports for the site. Once the proposal was reviewed and all risks considered, we began work by putting a surveillance schedule in place.

This schedule provided added peace of mind for the client, knowing that the works being carried out were meeting building regulations and standards. The foundations were inspected in February 2023, with ongoing site visits through to completion in December of the same year. Inspection reports were provided to the client after each site visit, with feedback at each key stage to keep them in the loop.


The Result

The 3-storey house based in Mere, Cheshire, was completed in December 2023. Finished to the highest of standards, comprising of 7 bedrooms, an open plan kitchen-living area, spacious office, cinema room and double garage.

Director of S3 Developments Ltd, Nathan Sproson, commented, “I am a Property Developer of 12 years and have used FMB Insurance for all my structural warranty requirements. I used FMB to cover my first development which was a barn conversion and then continued to use them for all my subsequent projects – now 14 properties."

I’ve found the team easy to deal with in terms of quoting and setting up the policy, key stage inspections and practical completion. Pricing has always been competitive compared to other providers, however, the key consideration for my provider was biased towards the quality of the brand. I believe FMB add credibility to my build, and most (if not all) lenders recognise and accept them. Jeremy in particular was great to work with as he was able to provide helpful advice and guidance throughout the process.” 

We’re proud to partner with S3 Developments Ltd and look forward to working alongside them on their next project.

Neil Bellas General Builders

Neil Bellas General Builders, based in the West Yorkshire town of Huddersfield, approached us in November 2019 with an application for a 10-year structural warranty on the construction of two houses.  

The site, formerly an old butcher’s shop in the town of Holmfirth – well known as the setting for the popular TV series, Last of the Summer Wine – is positioned on a steep incline.

An uneven landscape presented limited access and space for material storage, and would require detailed structural drawings to show how the construction methodology would lend itself to the challenging topography.

The client required a warranty that would be accepted by all UK mortgage lenders and provided full structural cover without any unnecessary exclusion clauses, which we were able to support them with.

The Project

Neil Bellas General Builders provided us with detailed structural reports and design details, including foundation design, earth supporting the semi-basement design and corroborating waterproofing system.

Our insurance team discussed the proposal and considered the risks involved. A formal quote was then sent to the developer with a surveillance schedule in place to oversee the works at critical stages including foundations, DPC, steel work, waterproofing systems to the basement areas, superstructure, through to completion.

The Result

Both houses were completed to an excellent standard in August 2023. With a split-level design – two storeys to the front and three storeys to the rear – the buildings blend in with surrounding properties and provide a comfortable, modern finish.

Neil Bellas himself commented, “Me and my business partner found the whole experience of working alongside the FMB Insurance team very good – there were no problems contacting staff when required. We would definitely choose FMB again and I would certainly recommend FMB Insurance services to my associates in the trade.”

Tiwana Construction Ltd

Suffolk-based developer, Tiwana Construction Ltd, approached us in November 2020 with an application for a 10-year structural warranty on a proposed barn conversion.

The existing structure was in a severely dilapidated condition, including badly distorted walls and roofline, rotten and infested timbers, major water egress, no drainage provision on-site and evidence of asbestos.

The building is Grade 2 Listed and the local planning authority imposed strict covenants, restricting the number of physical changes that could be made. Complying with current building regulations was difficult for certain aspects of the development. For example, the size of the windows would be too small for anybody to escape from a fire, so alternative solutions had to be provided to protect the future occupants in this event.

This was an unquestionably complex project and the developer was struggling to find a suitable insurance policy. It required a tailored warranty to cover the preservation, conversion and extension of the building, which we were able to provide.

The Project

Tiwana Construction Ltd provided us with detailed structural reports and design details, including the works required to stabilise the building and meet the requirements of current building regulations.

Our insurance team discussed the proposal and considered the risks involved. A formal quote was then sent to the developer with a surveillance schedule in place to oversee the works at critical stages from start to finish.

Asbestos removal, ground clearance, underpinning, damp proofing, timber replacement and preservation treatment were carried out along with the introduction of additional framework to support the roof structure before any of the rebuilding work could commence.

The Result

The conversion of Rippington Barn, Great Gransden, was completed in April 2023. The building provides modern, practical living space whilst retaining its periodic character and charm.

The developers had to strip everything back to the raw foundations of the barn – before rebuilding the whole structure, including the floor and roof which surrounds the existing treated timbers. They rebuilt the barn to a modern standard with a new wing featuring extensive glazing and metal roof.

With a focus on sustainability, eco-friendly systems were installed including a waste water treatment plant that disperses clean water back into the local waterway and protects the environment. Air source heat pumps also provide energy efficient heating and hot water in this well-insulated modern family home.

Director of Tiwana Construction Ltd, Harjinder Singh Tiwana, says, “Jeremy, the FMB surveyor, has been very helpful throughout this process, giving advice where he could. I have used FMB structural warranty insurance on a couple of projects, and I intend to continue this good relationship on future projects.”

     Swan Homes Ltd

Founded in 2009, Swan Homes specialises in new home developments. The company pride themselves on their exemplary reputation for creativity, quality and attention to detail, from sourcing plots to long after the client has moved in.

In order to reassure clients and provide a comprehensive construction service, Swan Homes uses FMB Insurance’s New Homes Warranties on all of their new developments. Covering the build for 10 years post-completion, these types of warranties give Swan Homes’ client’s the ultimate peace of mind.

For most UK mortgage lenders, a warranty is often required on the home in order to release money to the client. Without a warranty, the homeowner may struggle to sell the home on. If anything was to go wrong, it would be up to the homeowner to put right, which isn’t ideal when the client has spent a considerable amount of money.

Managing Director of Swan Homes, Adrian Swan, says, “Using FMB Insurance has been easy from the start. The team are knowledgeable, friendly and always on hand to help with any problem.”




Daniel Barella

Once you’ve settled into a home, you will likely want to make any changes which would make it a more comfortable place to live. Unfortunately, there is always a possibility that the planned improvements could go wrong.

Recently, a homeowner (our policyholder) experienced an example of this lack of quality including "multiple issues with tiles cracking and falling off the walls to free-standing bath and taps not being secured to the floor."

Fortunately for the homeowner, they held cover under FMB Insurance Domestic and Commercial policy for the damage caused by the builder and FMB Insurance was able to review the claim and offer remedial work swiftly. 

Without this cover, the cost for remedial work would have fallen solely to the policy holder. Speaking about his experience, Daniel Barella said,"The new builder FMB provided was 1,000 times better than the previous one and the finish was in a different league, I am very satisfied."
