Professional Oil Boiler
Installation Service

For rural Buckinghamshire properties without mains gas, oil boilers provide an efficient and reliable heating solution. At P&R Mechanical, we specialize in oil heating systems, offering comprehensive installation services tailored to your specific property requirements.

Our OFTEC registered engineers have extensive experience installing oil boilers across rural Buckinghamshire. We take a methodical approach to every installation, ensuring your oil heating system is correctly sized, safely installed, and optimally configured for maximum efficiency and performance.

Before recommending any oil boiler, we conduct a thorough assessment of your property, considering factors such as your home’s size, insulation, hot water demands, existing system (if any), and the location of your oil storage tank. This detailed evaluation ensures you receive a heating system perfectly suited to your rural property’s needs.

Main Oil Boiler Installation

Types of Oil Boilers We Install

Conventional Oil Boilers

Traditional oil boilers work with a cold water storage tank (usually in the loft) and a hot water cylinder. These systems are common in rural properties and offer reliable heating and hot water for larger homes.

Best suited for: Larger rural properties with existing traditional heating systems and multiple bathrooms.

Key benefits: Excellent for properties with low water pressure, supports high hot water demands across multiple bathrooms, works well with existing radiator systems.

System Oil Boilers

System oil boilers heat your central heating system directly and produce hot water for a storage cylinder. Major heating components are incorporated within the boiler itself for a more streamlined installation.

Best suited for: Medium to large rural homes with higher hot water requirements and multiple bathrooms.

Key benefits: Good water pressure, economical operation, compatibility with solar thermal systems, more compact than conventional systems.

Combi Oil Boilers

Oil combi boilers provide heating and hot water directly from the boiler without the need for separate tanks or cylinders. While less common than gas combi boilers, they offer space-saving benefits for smaller rural properties.

Best suited for: Smaller rural homes with limited space and moderate hot water demands.

Key benefits: No tanks required, hot water on demand, space-saving design, simple installation in properties with space constraints.

Oil Tank Considerations

A proper oil boiler installation requires careful attention to your oil storage tank. We can advise on:

  • Tank placement: Meeting safety regulations for minimum distances from buildings, boundaries, and ignition sources
  • Tank options: Single-skin or bunded (double-skinned) tanks based on capacity and location
  • Base requirements: Ensuring your tank rests on a suitable, level, and stable base
  • Compliance: Meeting all OFTEC and building regulations for oil storage
  • Pipework: Installing appropriate, protected oil supply lines from tank to boiler

If your existing oil tank needs replacement, we can handle this as part of your boiler installation project.

Frequently Asked Questions

Q: How much does an oil boiler installation cost?

Oil boiler installation costs typically range from £3,000 to £5,500, depending on the system type, boiler output, complexity of the installation, and whether a new oil tank is required. At P&R Mechanical, our oil boiler installations include the boiler unit, all required materials, labor, system testing, and OFTEC registration. If your existing oil tank needs replacement, this would add approximately £1,200-£2,000 to the project cost. We provide transparent, detailed quotations with no hidden charges, and can discuss financing options to help manage this investment.

Q: How long does an oil boiler installation take?

Most standard oil boiler replacements (where an oil system is already in place) can be completed within 1-2 days by our skilled P&R Mechanical engineers. For new oil heating system installations or those requiring oil tank replacement or relocation, the process typically takes 2-3 days. During your initial consultation and property survey, we’ll provide a clear timeframe for your specific installation. We work efficiently while ensuring every aspect of the installation meets stringent safety standards and our own high-quality benchmarks.

Q: Which oil boiler brand is most reliable?

Through years of installation experience across Buckinghamshire, we’ve found Worcester Bosch, Grant, and Firebird oil boilers to offer exceptional reliability, efficiency, and longevity. At P&R Mechanical, we’re accredited installers for these premium brands, allowing us to offer extended manufacturer warranties of up to 7 years on selected models. The most suitable boiler for your home depends on your specific requirements, and our OFTEC engineers will help you compare options based on your heating needs, property characteristics, and budget considerations.

Q: How efficient are modern oil boilers?

Modern oil boilers are significantly more efficient than older models, with the latest condensing oil boilers achieving efficiency ratings of 90-95%. At P&R Mechanical, we install only A-rated oil boilers that maximize fuel efficiency and minimize environmental impact. Upgrading from an older non-condensing oil boiler (typically 60-70% efficient) to a modern condensing model can reduce your heating bills by 15-30%, depending on your usage patterns and property characteristics. This improved efficiency not only saves money but also reduces carbon emissions from your heating system.

Q: What regulations apply to oil boiler installations?

Oil boiler installations are subject to strict regulations to ensure safety and compliance. All oil boiler work must be completed by an OFTEC registered engineer (or someone competent under building regulations). Key regulations include Building Regulations Part J (Combustion Appliances), OFTEC technical standards, and oil storage regulations that specify tank placement, protection measures, and minimum distances from buildings and boundaries. At P&R Mechanical, our OFTEC registered engineers ensure full compliance with all current regulations, providing the necessary certification upon completion.

Q: Can you replace my old oil boiler with a more efficient model?

Yes, upgrading from an older oil boiler to a modern, high-efficiency model is one of our specialties at P&R Mechanical. This type of replacement typically offers the simplest installation process, as we can often utilize much of the existing pipework and system infrastructure. The benefits of upgrading include improved reliability, enhanced control options, reduced fuel consumption, and lower carbon emissions. We can often complete a like-for-like replacement within a single day, minimizing disruption to your home while delivering significant performance improvements.
