Sound familiar?
Worried about getting your hot water upgrade wrong?
Weak showers that never improved after installation. A discharge pipe dripping with no clear explanation. Being told you need a full replacement when no one has actually assessed the system. Most problems with unvented cylinders come down to incorrect installation or poor system preparation, not the cylinder itself. You deserve a straight answer before anything is replaced.
Why choose us
Unvented cylinder installation done properly, from the system up.
System-first specification, not product-first installation
We do not start with a cylinder. We start with your water supply, system design, and usage demand. That is what determines whether an unvented system will actually perform properly.
We assess your system before specifying the cylinder
We check your mains supply, pipework condition, and existing heating setup before recommending anything. The right cylinder only works when everything it connects to is sound.
We verify mains pressure and flow rate, not assume it
Unvented cylinders depend entirely on incoming mains performance. We measure pressure and flow rate properly before specifying any cylinder to ensure it will deliver the performance expected.
A straight answer before any money is spent
If an unvented cylinder is not the right solution for your property, we will tell you. If it is, we will tell you exactly what is needed and why. No upsell, no pressure, just an honest assessment.
Fully certified from installation to handover
Unvented cylinders must be installed by G3-certified engineers and notified under Building Regulations. We handle everything: discharge pipework, expansion control, safety components, commissioning, and certification.
Correct discharge design, not just compliance
Temperature and pressure relief discharge pipework is designed and installed correctly for safety and long-term reliability. This is one of the most commonly incorrectly installed aspects of unvented systems.
G3 certified. Someone who picks up the phone.
Every engineer who carries out unvented cylinder work holds current G3 certification. If something is not right after we leave, you call us directly, not a call centre.
35+ years working with hot water systems across Scotland
Since 1990 we have installed and maintained unvented cylinders in Scottish homes. That experience shows in how we specify, prepare, and commission every job.
How it works
Your new cylinder in three clear steps
We handle everything from first contact to final certification. Just tell us about your property and we take it from there.
Tell us about your home
Fill in our quick enquiry form. No jargon, no lengthy questionnaires. Just the basics about your property and your hot water situation. We will take it from there.
We assess and install
An engineer visits, checks your mains supply and existing system, and fits the correctly specified cylinder. Discharge pipework, expansion vessel, safety components, commissioning, and documentation are all included. If preparation is needed first, we explain clearly what is required and why.
Powerful hot water, fully guaranteed
Your new cylinder is up and running, fully certified, and built to last. Strong pressure to every outlet, no more weak showers, and a system installed the right way from the start.
Before you replace
Been told you need a new cylinder? Or still battling pressure that was never fixed? Speak to us first.
Weak pressure, nuisance discharge, and cylinders that trip out are often symptoms of incorrect installation or a system that was never properly assessed. A new cylinder installed into the same unprepared system will reproduce the same problems within months, and we regularly correct exactly that mistake. A proper assessment tells you whether replacement is genuinely necessary before anything is spent.
Transparent pricing
Cylinder assessment and installation costs
You receive a clear fixed quotation after assessment. No guesswork, no hidden costs.
Cylinder Assessment
£225 + VAT
A professional on-site assessment of your mains supply, pipework, and system suitability.
If you proceed with installation, this cost is deducted from the final price.
Typical Installation
£1,800 – £3,500 + VAT
The final cost depends on:
- Cylinder size and specification
- Mains upgrades, if required
- Pipework modifications
- System preparation work
The difference it makes
Most unvented cylinder installations skip the step that matters most
What often happens:
- Cylinder quoted without checking mains supply
- Installation completed without system preparation
- Pressure issues or discharge problems return
- No clear explanation or accountability
What we do instead:
- We check your mains supply, pipework, and system condition before recommending a single thing
- If your existing setup can be corrected without replacement, we will tell you
- If a new cylinder is the right call, we prepare everything correctly so the same problems do not come back
- You get a clear answer before any money is spent
Service Coverage
Where we install
Unvented cylinder installation requires G3-certified engineers, correct system preparation, and accountable after-care. For this reason, installation is limited to our core service regions where we can maintain full control over quality, response times, and ongoing support.
Assessment Availability
Cylinder assessments may be available outside these areas. Where appropriate, we can advise on system suitability, mains supply conditions, and whether an unvented cylinder is the right option before any installation is considered.
