THE CRS MATRIX APPROACH
A Boiler Installation Should Last.
We Make Sure It Does.
A new boiler is more than a replacement appliance. It’s an investment in the comfort, safety and long-term reliability of your property.
The right installation begins long before the new boiler is fitted. We consider the property’s heating requirements, the condition of the existing system and the preparation needed to support reliable performance.
Our approach combines careful specification, professional workmanship and appropriate commissioning, with clear guidance throughout.
The CRS Matrix Engineering Standards
Correct Boiler Sizing
A boiler selected for the property’s heating and hot-water requirements.
System Preparation

Long-Term Reliability
Installation decisions that consider ongoing performance and maintenance.
Engineering Workmanship
Careful installation, appropriate controls and attention to detail.
Compliance & Commissioning

Every property is different. The right investment begins with the right specification.

HONEST ENGINEERING ADVICE
Repair or Replace?
A new boiler isn’t always the right answer.
We consider the condition, reliability and repairability of your existing boiler alongside the wider heating system. Where repair remains safe and practical, we’ll explain that option. Where replacement offers better long-term value, we’ll help you understand why.
THE INSTALLATION EXPERIENCE
Your Installation, Carefully Managed.
From removing the old boiler to commissioning the new system, every stage deserves proper attention.

PROTECTING YOUR INVESTMENT
The Right Preparation Matters.
A new boiler performs best when the heating system around it is properly prepared.
The condition of the existing heating system can affect the performance and reliability of a replacement boiler.
Our engineers assess the system and recommend appropriate cleaning, water treatment and protection measures in accordance with the installation requirements and applicable manufacturer guidance.
Where additional work is necessary, we explain the reasons and identify it within the proposed specification.
System Cleaning & Flushing
Appropriate cleaning can address sludge, magnetite and debris where necessary. The method is selected to suit the condition of the existing heating system.
Magnetic Filtration
Where appropriate, a suitable system filter can help capture circulating magnetic debris and protect relevant components.
Chemical Cleaning & Water Treatment
Cleaning and treatment are specified to suit the system’s condition and applicable manufacturer requirements.
Heating Controls
Suitable controls form part of the installation specification. Additional smart-control functionality may be offered as an upgrade where appropriate.
The scope of system preparation and any upgrades depends on the existing heating system and the agreed quotation.

OUR CHOICE OF MANUFACTURER
Confidence Beyond the Installation.
The boiler matters. The support behind it matters just as much.
We believe a good boiler installation should be supported long after the engineer has left. That’s one reason CRS Matrix has chosen to become a Worcester Bosch Accredited Installer.
Our experience of Worcester Bosch’s technical support, parts availability and customer service gives us confidence in recommending its products. We value the support behind the appliance as well as its performance in your home.
Your choice matters. We also recognise that every property is different. If you prefer another manufacturer, we’re happy to consider your preference and recommend a suitable specification.
The boiler model, guarantee and final price will be confirmed individually.
We have our preferred manufacturers, but your preference matters too. Whatever boiler you choose, our engineering standards remain the same.

YOUR QUESTIONS, ANSWERED
Boiler Installation FAQs
Clear answers, from the first indicative price to the final handover.
Whether you’re a homeowner planning ahead or a landlord managing an unexpected breakdown, here are the questions we’re most often asked.
How much does a new boiler installation cost in Leicester?
Our CRS Matrix Signature Installation starts from £2,950 including VAT for a like-for-like combi boiler replacement. It includes an appropriately specified Worcester Bosch boiler, controls, magnetic filtration, system cleaning and treatment, commissioning and handover.
Conversions, relocation or additional work may change the final price. We’ll explain the specification and provide a quotation before work begins.
Can I get an instant boiler installation price before speaking to an engineer?
Yes. Our online quotation tool gives an initial indicative price based on answers about your property and heating requirements.
It’s a useful starting point, whether you’re planning ahead or need a replacement sooner. The final specification and price are confirmed after an appropriate assessment.
Can I speak to James or Sham before deciding?
Yes. If you would prefer a conversation, contact our team and ask to arrange a callback with James or Sham.
Tell us about your property and the best time to reach you, and we’ll coordinate a suitable conversation subject to availability.
You can obtain an indicative price first if that helps.
My boiler has broken down. Can you arrange an urgent replacement?
Tell us if you have no heating or hot water, especially if someone in the property needs additional support.
We’ll discuss the circumstances, assess the appropriate next steps and consider whether repair or replacement is suitable.
We may be able to discuss temporary electric heating where appropriate and subject to availability.
We cannot guarantee next-day installation or emergency attendance.
Do you offer temporary heating while a boiler is being repaired or replaced?
Temporary electric fan heaters may be available where appropriate and subject to availability.
Please tell us about any vulnerable occupants or urgent heating needs when you contact the team so we can discuss practical options.
Temporary heating does not replace the need to address the underlying boiler fault.
How long does it take to replace a combi boiler?
A straightforward like-for-like combi boiler replacement can often be completed in around one working day.
Conversions, relocation, system preparation or additional pipework can take longer.
We’ll explain the expected programme after assessing the property and agreeing the specification.
What is included in your Signature Installation?
Our starting specification includes a suitable Worcester Bosch combi boiler, appropriate heating controls and standard flue arrangement, a magnetic system filter, suitable chemical cleaning and water treatment, professional installation, commissioning, applicable certification and a customer handover.
The precise scope is set out in your individual quotation.
Does a new Worcester Bosch boiler come with a 10-year guarantee?
Our Signature Installation is intended to use an eligible Worcester Bosch model with a 10-year manufacturer guarantee, subject to the manufacturer’s terms and conditions.
We’ll confirm the selected model, guarantee eligibility and registration requirements in your quotation.
Do you only install Worcester Bosch boilers?
No. We are Worcester Bosch Accredited Installers and recommend the brand because of our experience with its technical support, parts availability and customer service.
If you prefer another manufacturer, we can discuss a suitable alternative.
Our engineering standards remain the same.
Will my existing heating system need flushing or a new filter?
We assess the existing system and select suitable preparation and protection.
Our Signature Installation includes appropriate cleaning, water treatment and magnetic filtration.
The method depends on the system’s condition; a full powerflush is not automatically required for every property.
Any additional work will be explained in the quotation.
Can you coordinate a boiler replacement with my tenant or letting agent?
Yes. Where authorised, our team can liaise with the letting agent or tenant about access, scheduling and communication.
We understand the importance of restoring heating and hot water in rented properties and will discuss appropriate arrangements, including temporary heating where available.
What paperwork will I receive after installation?
We provide the relevant commissioning and installation documentation, applicable Building Control notification and manufacturer guarantee information.
We’ll also explain the new boiler and controls at handover.
MyMatrixHub® is designed to help keep relevant property records together. Ask our team about the available access and record arrangements.
Prefer to Talk It Through?
Ask our team to arrange a conversation with James or Sham about your boiler installation.
