We install replacement boilers for properties experiencing poor heating performance or ongoing boiler issues. Our engineers work with gas, oil, and LPG systems and assess your current setup before advising on a suitable replacement. Upgrading your boiler can improve efficiency and hot water performance throughout the property. We provide clear and practical guidance during the installation process.
Allstar Systems delivers boiler repair services for customers dealing with heating and hot water interruptions. Our engineers diagnose faults professionally to ensure the correct repair approach is recommended. We repair gas, oil and LPG boilers in both domestic and commercial properties. Heating system concerns involving radiators, circulation or controls can also be assessed by our team. We work to restore boiler function efficiently while providing straightforward and reliable guidance.
At Allstar Systems, we carry out power flushing services to remove sludge and debris from heating systems with circulation problems. We assess the heating system in advance to determine whether flushing is suitable or if alternative work is required. Common signs include noisy boilers, poor heat output, and radiators heating unevenly. Our engineers focus on restoring cleaner circulation and improving the overall efficiency of the system.
We offer complete hot water system services for properties experiencing problems with heating performance or water supply reliability. Our engineers repair faults such as leaking cylinders, fluctuating temperatures, faulty controls, and low pressure systems. Every installation or repair begins with a full assessment of your propertys hot water requirements. We aim to provide durable solutions that improve overall system performance and efficiency.
Our engineers provide underfloor heating services that are planned around the needs of your property and heating system. We install electric underfloor heating for smaller areas and wet systems for larger spaces requiring steady heat distribution. Alongside installations, we repair faults, improve controls, and upgrade outdated systems. Every underfloor heating project is assessed thoroughly to ensure reliable and efficient operation.
We specialise in emergency plumbing repairs for properties experiencing urgent plumbing faults. Quick response times allow us to reduce the impact of leaks, burst pipes, and related issues. Our service is available for both domestic and commercial plumbing requirements. Customers choose our company because we provide reliable repairs, professional advice, and consistently high standards of workmanship.
We create luxury bathrooms that are carefully designed to suit both contemporary and traditional properties. Our services include en suites, cloakrooms, wet rooms, and walk-in shower installations using premium fittings and materials. Attention is given to every stage of the installation, from plumbing performance to the final finishing details. Each project is completed with professionalism and precision.
Our commercial boiler servicing is intended to help commercial premises maintain safe, efficient and dependable heating systems throughout the year. We carry out detailed inspections of boilers and associated heating equipment, identifying maintenance requirements and operational concerns. We service gas, LPG and oil commercial boilers for buildings such as schools, offices, hotels and healthcare facilities requiring reliable heating performance.
We carry out commercial gas and LPG projects for a variety of commercial properties, including healthcare facilities, retail spaces, and shared commercial sites. Services include commercial gas installations, testing, purging, inspections, and pipework works. Every project begins with a detailed site assessment to identify the safest and most effective route forward. We remain focused on compliance and communication throughout the process. After a few months, we approached Allstar again for a heating system update, involving a boiler change and system update. We received great service. The team were punctual, polite, professional and took a great deal of pride in their work. We opted for an external boiler, which involved a good deal of pipe renewal. Despite miserable weather, they ensured that everything was to the highest standard and no corners were cut. Will made sure the system operated safely and correctly and I understood how to program the system and could spot any faults. Will, Ash, Bank and Geordie did an excellent job. They cleared up after themselves and we now have a beautiful new system. Many thanks to all.
Ashley was very professional, friendly, kindly showing and explaining some parts to me and what it could mean/need. Will be booking in with them again for any further issues and servicing needs.
Thanks guys!
He and Ash worked hard in horrible weather to ensure the new boiler was fitted and running well. To say they have made a difference to our house is an understatement, our radiators are warmer, the water pressure has improved 10 fold and we are far more relaxed knowing that the boiler is safe. I'd happily recommend them to anyone in need of a heating engineer.
Our stars must have been in alignment that day: the replacement we had selected was in stock and with a bit of juggling and non-stop hard graft the new boiler was up and running just 27 hours later, with a beautiful array of orderly copper piping replacing the Heath Robinson arrangement that had gone before. Everything was left clean and tidy,, we're enjoying the greatly improved heating system, and last but not least, looking forward to significantly lower bills.
We took a punt on Will and it has been money well spent. Thank you!
Allstar visited within a couple of days and not only deemed it terminal but that it had been installed incorrectly, illegally, by the original plumber.
Within a week they had sourced a new tank and installed in line with the building regulations.
One cannot ask for better service than that.
If you want, or have got an unvented mains hot water tank, ("Megaflow"), these are your guys. They have the essential additional qualifications over and above the usual "Gas Safe" one.
Boiler failed to work 6am Saturday morning, contacted Allstar Systems, instant response and engineer out by lunchtime. Diagnosed problem straight away, all fixed & hot water and heating back on by the afternoon!
Do not hesitate to contact Allstar Systems, very genuine and even contacted us later to make sure everything was all going well.
Well done Allstar, will be recommending you to friends and family.
