Completion & Sign-Off

JLES manages the works, secures authority approval and progresses the site straight into maintenance.

When to appoint us

Prestart:

By involving JLES at the start of the project, you can tender the Estate Completion Works on a like-for-like basis against the Groundworker. This gives you a clear comparison quotation for completion, as well as the option to appoint JLES independently to deliver the Estate Completion Works.

As the build progresses, you can also appoint JLES as an independent agent to liaise with the relevant Adopting Authorities and undertake essential investigation works. This allows any defective works to be identified early and provides a definitive scope of works required to obtain approval and sign-off of the roads and sewers.

This can be undertaken on a phase-by-phase basis, in tandem with the build programme, or towards the end of the development prior to final surfacing. The aim is to bring the adoption process into focus earlier, giving you the opportunity to identify and address issues sooner, rather than allowing them to contribute to the backlog of legacy sites.

It also gives you greater flexibility when closing sites down, with the option to appoint a specialist contractor to take responsibility for completing the project and infrastructure.

Post-build:

Whilst we strongly advocate for JLES to be your preferred Estate Completion Contractor from the outset, we recognise that this isn't always the case. Sometimes our services are only required when a project starts to experience issues.

In these circumstances, JLES can step in to help you complete sites where the Groundworker has gone into administration, construction issues have arisen, or where you simply want your Groundworkers to focus their resources on new site starts.

We can initially provide a quotation based on an existing remedial list. However, our preferred approach is to undertake detailed investigation works to establish a definitive scope of works.

This enables us to provide you with a 'Lump Sum, Fixed Cost' to complete the infrastructure to an adoptable standard, giving you greater cost certainty and a clear route through to completion and adoption.

The Difference Between “Finished” and “Adoptable

A Specialist Approach to Estate Completion, From Day One.

JLES brings adoption expertise into the programme early, aligning design, construction and authority requirements from the outset. The result is fixed-fee, results-based estate completion that removes rework and accelerates adoption.

Before After

Results Delivered Across the UK.

Whether we’re appointed early or brought in later, our process is designed to remove uncertainty, reduce rework and drive estates to adoption as efficiently as possible.

Frequently Asked Questions

Discover quick answers to common questions about our services and processes.

What is estate completion?

Estate completion is the process of completing outstanding construction, remedial and infrastructure works on a development so that it can meet the requirements for final completion and adoption. This can include carriageways, footways, drainage, block paving and other infrastructure that remains outstanding after the original construction phase.

What does estate completion involve?

Estate completion can involve anything from a small number of outstanding remedial works through to a substantial package of highway, drainage and infrastructure works. JLES first establishes the condition of the site and the requirements for completion, then develops a defined scope of works and delivers the necessary construction package.

Can JLES complete an unfinished housing development?

Yes. JLES can take on outstanding works where a development has not reached the required standard for completion or adoption. We investigate the current condition of the site, establish what remains outstanding and take responsibility for delivering the agreed works.

Can estate completion works be carried out after residents have moved in?

Yes. JLES regularly works within live residential developments where residents are already occupying properties. Works are planned and coordinated around the existing site environment, with consideration given to access, residents and other ongoing activities.

Can JLES complete a development if the original contractor is no longer involved?

Yes. JLES can take responsibility for outstanding estate completion works where the original contractor is no longer available, is unable to complete the works or is not being used for the remaining scope. We can assess the current condition of the development and establish what is required to achieve completion.

Can estate completion works be fixed price?

Yes. JLES can provide a fixed-cost proposal for the agreed estate completion works. This gives the developer greater certainty over the cost of completing the outstanding works.

The best way for you to understand more about us and how we work, is to hear from our clients themselves…

JLES were engaged on a project of ours which involved the progression of several phases to achieve maintenance. JLES undertook the required works, liaised with Anglian Water and also the residents delivering great results, allowing me to focus my time and effort on other schemes. Overall, JLES provided an efficient service with good communication throughout, I would recommend their services to anybody who requires adoption works.

Persimmon Homes – Adoptions Engineer

We appointed JLES to complete the complex Section 278 works on this scheme, which required night-time works, significant traffic management and extensive engineering supervision and management. As JLES work on a fixed fee, lump sum cost model, we were able to utilise their consult and construct turnkey offering and achieved sign off on the S278 works with ZERO Bellway internal resource used. We have now engaged JLES on several complex schemes, having the ability to offload sites to an outsourced company who take on all of the hassle and risk – it’s the perfect solution for us! They continue to impress me with their professionalism, quality of workmanship and regular communication throughout the process. They are very transparent and everything that they promise is delivered on time and to the highest quality. I would definitely utilise your services again.

Bellway Homes – Technical Director

We have worked with JLES’ Northern region on multiple projects to progress our sites to adoption, we have previously had issues with main contractors cancelling last minute & being unable to facilitate the scope of works, which was putting our adoptions projects to a halt. Since working with JLES, we have achieved adoption of multiple highways and sewers. The process is organised and managed well, from initial contact to the completion of works the management team keep in touch at all stages and ensure our team is updated. Not only did JLES achieve the adoption certificate for us, but they also planted trees through the national trust on behalf of beyond housing and we received a certificate for this as well. The performance, communication, quality, and social value of JLES has been 10/10 throughout our time working with them.

Beyond Housing – Development Manager

JLES have been a consultant of ours for a while, and we hope to continue working with them in the long term. The engineers hold a high level of competence and knowledge on highway and sewer adoptions, so can facilitate any scope of works handed over to them and have always achieved the desired results on our projects. Even on our complex legacy sites with outstanding bonds & varying issues JLES have worked in a pro-active manner, providing weekly updates and liaising with theAdopting Authority to ensure our sites are processed in the agreed timeframe with no fuss. They carry their works out to the highest standard and remain professional at all points

McCarthy & Stone – Engineering Manager

Due to a shortage of in-house resource and a general push by our management to reduce bond liabilities, we engaged with JLES who successfully achieved the vesting certificated in a timely manner. The bond on this site was very old and progress was proving to be slow because of our lack of resource. However, JLES made the whole process easy, and we knew that we could rely on them without micro-manging, so we were able to focus on our current and upcoming projects. Because of the reduction in the bond liability and the benefits we experienced as a team, I would have to rate JLES 10/10 for the quality of works and performance on this project.

Cala Homes – Senior Engineering Manager

JLES have successfully progressed multiple sites of ours to adoption in the past, so when a scheme which was many years old and had a lot of alternations made by residents came to our attention, we knew JLES would be the best contractor to deal with this on our behalf. JLES have a great relationship with local authorities which makes it easy for them to progress agreements, they engaged with NYCC on this project for us and the agreement is now successfully adopted. This and the regular communication from JLES contribute to how they take the stress away from complex projects like this.

Broadacres – Construction Manager

I liaised with JLES when I previously worked for a different developer and they achieved some great results for us, so when I was faced with this legacy project that had been completed for some time, but never adopted, I knew JLES would be my best option. JLES took full control of the adoption, saving me time so I could work on current developments. Their straightforward approach makes them easy to work with and as they provide regular updates, I don’t need to worry about the site at all.

Tilia Homes – Development Manager

We were struggling to secure adoption of the drainage system on this large post-build site and engaged with JLES to utilise their expertise and their great relationship with the adopting authority. The site required remedial works, and the changing requirements of the adopting authority made the process to complicated for our internal resource to handle. JLES completed the remedial works to a high standard and the adoption certificate was issued in a timely fashion, as JLES was able to cut through the adopting authority’s process. The friendly and personal approach JLES provide makes working with them enjoyable and simple. I am very impressed with the level of works carried out by JLES.

BAE Systems – Real Estate Manager

We have a lack of internal resource so struggle to progress adoptions inhouse, this site was a long standing S104 site, and I knew from previously working with JLES that they would be able to achieve adoption of the sewers. JLES provide a step-by-step structure along with a fixed fee which they stick to, it is an efficient process and the completion of the S104 works didn’t only achieve adoption but also released the bond and allowed for the next phases of the development works to be completed to the local & water authorities satisfaction. They have a great relationship with both authorities which contributed to the progression of this site and the clear, regular reporting took away the hassle & fuss which usually comes with these types of projects.

O&H properties – Technical Manager

JLES facilitated the immediate adoption of the sewer network throughout the entire scheme and have completed the remedial works and final surfacing to 4 phases of the project, achieving sign-off by Coventry City Council. All works were completed on programme and with very little resource expended by Taylor Wimpey, resulting with the scheme being placed onto its maintenance period. We are looking forward to them concluding the remaining phases and achieving final adoption of the scheme in the near future.

Taylor Wimpey - Technical Director

We appointed JLES to progress the sewers to adoption and undertake the final surfacing and estate completion works via their fixed fee – zero extras package. All works were completed 3 months ahead of schedule and they even managed to progress the sewers straight to vesting with no maintenance period. JLES’ constant on-site presence proved very beneficial in dealing with any urgent queries for our residents, I would recommend them to other developers.

Taylor Wimpey – Commercial Director

We utilised JLES Group’s Post Built Adoption Package on our legacy development in Milton Keynes which required the road & sewers being brought up to an adoptable standard including drainage, street lighting installation and final surfacing of the adoptable carriageway. We were very impressed with their ability to manage the various disciplines including their overall control from a Customer Care point of view. I’d recommend their services going forward.

Vistry Group – Commercial Manager

JLES have successfully undertaken a demanding residential estate completion project at Hagley on behalf of Cala Homes. The works were completed to adoptable standards in a timely and professional manner, despite Covid restrictions, and included significant liaison with existing residents and strict accordance to Health & Safety standards all undertaken successfully despite the restrictive working requirements.

Worcestershire County Council – Project Manager

It’s not very often here I can say the Section 278 works have gone as smoothly and well executed, as they have on this scheme.

Northumberland County Council – Clerk of Works

JLES are extremely professional, I am very pleased with the S38 works carried out and their communication, which is second to none. Across the site, the service was excellent, any issues were dealt with accordingly and we were provided with regular updates.

Milton Keynes Council – Senior Engineer

"JLES provide a unique solution to the construction industry when dealing with Section 38, 104, 278 adoptions. We find their approach and adoption management system unparalleled, and they provide robust proposals to enable completion certificates to be released along with associated bond reductions. They always provide regular updates, are reactive to our target timeframes and have good relations with Adopting Authorities. I have formed some good relations with their team and trust that they always have our best interests at heart. I would recommend their services to any colleagues within the housebuilding industry"

Infrastructure Manager – Crest Nicholson SW

"Chris and his team at JLES Exeter are really easy to work with. They go above and beyond to provide quick response times and are always on hand to assist with any unexpected issues. Working with JLES has been positive for us and has given us more space to focus on our main priorities and continue growing our business"

Technical Coordinator – Cavanna Homes

“Morro worked with JLES on the adoption of roads and sewers at Court Street, Woodville, a site with a lot of historic infrastructure to untangle. JLES handled the process professionally from start to finish and took what was a genuinely stressful adoption off our hands. Their knowledge of the process and clear communication throughout meant we always knew where things stood. We'd happily work with them again and would recommend them to anyone facing a similarly complicated adoption”

Infrastructure Manger – Morro Partnerships

“Following the administration of a previous contractor, this site was left with incomplete S38 and S104 works, preventing adoption by Yorkshire Water and the Local Authority. JLES were appointed based on a strong recommendation and prior performance on a similar scheme. They quickly established the required scope and delivered the outstanding work to a high standard with minimal disruption to residents. The site was successfully progressed towards adoption, helping remove ongoing maintenance liability from the developer while transferring future responsibility to the relevant adopting authorities.”
