Construction Site Services Bristol & UK

Trusted on high-security and public sector projects. Our teams hold the security clearances and accreditations required to work on Ministry of Defence sites and live HM Prison estate projects — including the documentation, vetting, and CDM compliance these environments demand. If your project has elevated security or compliance requirements, you’re talking to the right contractor.

What You Get When You Work with ETS

When you’re managing a construction programme, you don’t just need trades — you need a single accountable contractor who shows up, gets it right, and keeps your site moving.

That’s where we come in.

We support principal contractors, developers, and project managers across the UK with reliable temporary site services designed to slot cleanly into your build programme. Whether you’re mobilising a new site, phasing works across multiple plots, or bridging the gap before your M&E contractor arrives, we deliver power, water, welfare, heating, and lighting — when you need it, exactly where you need it.

The Contractor You Call Before You’ve Called the Other Contractor

When you’re under pressure to get a site live, you often can’t wait for the full M&E tender to wrap up before work has to start. Welfare units need power. The first trades need lighting. The principal contractor needs the site CDM-compliant from day one — not whenever the procurement process finishes.

We’re often the first contractor on site, mobilised before the main mechanical and electrical provider has even been appointed. We get your temporary power, water, lighting, welfare, and heating live — so your programme starts on time and your team isn’t sitting around waiting for someone else to be picked.

When the permanent M&E contractor is finally appointed, we hand over cleanly. No conflict, no overlap, no scope confusion. Just a site that’s already operational and ready for them to plug into.

We Also Handle the Things Other Contractors Won’t Touch

Most contractors like predictable, well-defined projects with clear timelines. We do too — but we also handle the awkward middle ground where others walk away.

Refurbishment of existing site infrastructure — old welfare units, tired distribution boards, ageing power runs, drainage that needs reworking. If the existing site setup isn’t fit for purpose, we’ll fix it rather than make you start from scratch.
Urgent, short-notice work — broken power on a live site, failed heating in winter, a welfare unit that’s stopped working. If your site has a problem today, we can usually be on site within 24 hours.
Bridging the M&E gap — interim works that keep your programme moving while the main M&E contract is being decided, tendered, or mobilised.
Phased site rollouts — where the site grows in stages and your temporary services need to grow with it. We scope for the whole build from the start, not just phase one.
Multi-site programmes — where you need consistent standards across dozens of sites, not just one. Our teams deliver to the same specification whether it’s one location or fifty.

You don’t need to wait for the right contractor to be appointed. Call us first, get the site live, and bring the others in when you’re ready.

A Straightforward Process That Puts You in Control

Every site is different — and so is every project. That’s why we don’t offer cookie-cutter packages. Instead, we start by understanding what matters most to you: your programme, your site constraints, your workforce numbers, and your compliance requirements.

Then we build a plan around it.

From your first call to final handover, our process is clear, collaborative, and focused on delivering a setup you’re confident in — whether we’re installing temporary power, welfare, heating, water, or a full site infrastructure package.

We’ve spent decades working alongside principal contractors, developers, and project managers who expect things done right, with minimal disruption — and that’s exactly what we deliver.

Let’s plan a smarter, smoother site setup for your next project.

CDM 2015 Compliance — Built Into Everything We Deliver

The Construction (Design and Management) Regulations 2015 aren’t optional. They’re the legal framework that governs how every UK construction site is set up, run, and handed over — and getting compliance wrong doesn’t just risk enforcement, it risks your programme, your budget, and your reputation.

At ETS, CDM 2015 compliance isn’t a checkbox at the end of the job. It’s built into how we scope, install, and document every temporary site services package we deliver.

What that means in practice:

Welfare that meets Schedule 2 — toilets, wash facilities, hot water, kitchen areas, drying rooms, and rest areas sized to your workforce numbers and site duration.
Electrical installations to BS 7671 — the IET Wiring Regulations. Every distribution board, cable run, and connection tested and certified. Test certificates issued as part of the handover pack.
Water hygiene compliance — plumbing and hot water systems designed and installed to prevent legionella risks, with hygiene checks documented.
Fire safety integrated — temporary fire alarms, emergency lighting, and escape route lighting where site conditions require it.
RAMS for every install — risk assessments and method statements produced before we mobilise. Your principal contractor gets what they need for their CDM file without chasing.
Documentation on handover — a full O&M pack covering what we installed, how it was tested, and what your ongoing responsibilities are.

When HSE turns up — and on serious projects they usually do — you’ll have the paperwork to prove your temporary services were installed, tested, and maintained correctly.

How Pricing Works — Honestly

Every site is different, so pricing is always tailored. That means we can’t publish fixed rates online — and any contractor who does is either guessing or padding.

What we can do is tell you honestly how our pricing process works.

We won’t quote fixed price over the phone. Any contractor who does hasn’t seen your site, doesn’t understand your programme, and is either wrong or expensive.

We will give you an indicative range on a first call. A 20-minute conversation covering scope, workforce numbers, timeline, and site conditions is usually enough for us to tell you whether you’re looking at £10k, £50k, or £250k+ — enough to know if we’re in the right ballpark before you invest more time.

We will visit the site before we quote properly. Every site has surprises. Access constraints, utility connection points, existing infrastructure quality, ground conditions — all these affect the price. Finding them before we quote is cheaper than finding them mid-project.

Our proposals are itemised. You’ll see exactly what’s included in each element (power, plumbing, welfare, heating, lighting), what’s assumed, and what’s excluded. So you can compare our quote properly against others — like-for-like.

We’re not the cheapest, and we don’t try to be. What you get for the money is a single accountable contractor handling the whole setup, all the compliance documentation in one place, and a team that’s been doing this since 1979.

Frequently Asked Questions

Common questions we hear from project managers, principal contractors, and developers planning their construction site setup.

How quickly can you get temporary power and welfare set up on a new site?

For most sites in our core area, we can carry out a site survey within 3–5 working days of your call, and have temporary power, welfare, and lighting installed within 1–2 weeks of order — depending on scope and any utility connections required.

For urgent or short-notice projects, we’ll work with you to find the fastest realistic timeline. The earlier you involve us, the smoother the setup. Ideally we’d be talking to you at the planning stage, not the week before you break ground.

Do you handle CDM 2015 compliance for temporary site services?

Yes. Every installation we deliver is designed and installed to meet the Construction (Design and Management) Regulations 2015. That covers temporary electrical installations to BS 7671 (the IET Wiring Regulations), welfare facilities meeting Schedule 2 requirements, and safe water and drainage systems.

We provide all relevant test certificates, RAMS (risk assessments and method statements), and documentation your principal contractor needs to satisfy HSE requirements. You won’t need to chase paperwork.

Can you work on live sites where other trades are already operating?

Absolutely — it’s one of the things we do most. Whether you’re phasing works across multiple plots, adding a new welfare block mid-project, or scaling power capacity as the build progresses, we’re used to working around live trades without disrupting their programme.

Our team will coordinate directly with your site manager, attend pre-start meetings, and adapt installation timing to suit your wider build schedule.

What’s typically included in a construction site setup package?

A standard setup usually includes some combination of: temporary power distribution (DBs, supplies to cabins and tools), site lighting and lighting towers, plumbing and water supply to welfare units, drainage and waste management, temporary heating for welfare areas and frost protection, and temporary fire and security alarm systems.

We tailor every package to your specific site — there’s no one-size-fits-all. The best way to scope it is a 20-minute call followed by a site visit. Then we’ll come back with a clear, itemised proposal so you know exactly what’s included and what it costs.

Do you cover sites outside Bristol and the South West?

Our core delivery area is a 60-mile radius from Bristol and from Taunton — covering the South West, South Wales, the Midlands, Thames Valley, and the south coast. From Bath and Bristol across to Cardiff, Newport, and Swansea, down to Exeter, Plymouth, and Bournemouth, and up to Gloucester, Cheltenham, Worcester, and Birmingham.

For multi-site rollouts or projects further afield, we work UK-wide. We’ve delivered for national brands and main contractors across England and Wales — talk to us about your specific locations and we’ll tell you honestly whether we’re the right fit.

How does pricing work for construction site services?

Every site is different, so pricing is always tailored — but it’s never opaque. After a site visit, we provide a clear, itemised proposal that breaks down each element (power, plumbing, welfare, heating, lighting) so you can see exactly what’s included and how it adds up.

We’re not the cheapest, and we don’t try to be. What you get for the money is a single accountable contractor handling the whole setup, all the compliance documentation in one place, and a team that’s been doing this since 1979.

Can you work on MOD or prison estate projects?

Yes. Our teams hold the security clearances and accreditations required to work on Ministry of Defence sites and live HM Prison estate projects. We’re familiar with the documentation, vetting processes, and CDM 2015 compliance that these environments require.

If your project has elevated security or compliance requirements, we can discuss the specific clearances and procedures needed on a case-by-case basis.

What happens when the main M&E contractor is appointed — do we have to remove your services?

No. Our temporary site services are designed to hand over cleanly to the permanent M&E contractor when they arrive. We document everything — what’s installed, how it’s configured, and where it connects — so their teams can plug straight in and start delivering the permanent works.

In most cases, our temporary setup stays operational until the permanent installations are ready to take over. There’s no gap, no downtime, and no scope confusion between the two.

Do you handle emergency and short-notice work?

Yes. If your site has a problem today — broken power, failed heating in winter, a welfare unit that’s stopped working, or a temporary installation from another contractor that isn’t fit for purpose — we can usually be on site within 24 hours in our core delivery area.

Call us on 0117 9414 666 and we’ll get someone to you as fast as we can.

What accreditations do you hold?

We’re accredited with NICEIC (for our electrical work), CHAS, Constructionline, SMAS Worksafe, and Alcumus SafeContractor. Our engineers hold CSCS cards appropriate to their trade, and our team is trained to work in live and critical environments.

For public sector, MOD, and prison estate work, we hold the additional security clearances and vetting these projects require.
