At Thames Valley Heating & Cooling, we are a local heating business serving homeowners across Berkshire, Surrey, Hampshire and parts of Oxfordshire. Led by Harry Brown, our company draws on more than 16 years of experience within the heating industry. Harry founded the business in 2019 after working in the trade and established it around a clear principle: heating systems should be properly specified, fairly priced and built to last. We continue to follow that principle on every job, providing honest advice and dependable workmanship. Rather than offering a standard solution without considering the property, we first examine the home, the existing heating arrangement and its everyday use. This enables us to determine whether a new boiler, a hot water upgrade or a complete heating installation is the most suitable approach.A consistent in-house team of Gas Safe registered engineers carries out our work, with Harry providing leadership throughout. Customers therefore deal with the same team rather than subcontractors or unknown tradespeople, allowing us to maintain control over quality, communication and timings. Having completed more than 3,000 heating jobs, we have extensive experience with boiler installations, repairs, underfloor heating and hot water systems. We take care with every stage, from neat pipework and correct system setup to thorough testing before completion. We also ensure that customers receive clear updates and that their homes are treated respectfully, leaving the working area clean and tidy. Our service extends across towns such as Reading, Wokingham, Bracknell, Ascot, Farnham and the surrounding areas.

Services
Our new boiler installation service is designed around how your home uses heating and hot water. We assess the property before recommending an appropriately sized system, then remove the existing boiler and complete the required installation and connections. Final testing, commissioning and a practical handover ensure the new system operates correctly from the outset. 
We provide professional boiler repairs with an emphasis on accurate diagnosis and lasting reliability. Rather than concentrating only on the visible symptom, we investigate the cause through system checks and component testing. The recommended repair and its price are explained beforehand. Correct repair methods are then used, with thorough testing completed to confirm the system is operating safely. 
Our underfloor heating installations are planned to provide reliable warmth across the entire floor area while making efficient use of lower operating temperatures. We adapt the design to the property and its heating requirements, considering insulation, floor construction, room usage and pipe configuration. From initial assessment through installation and final commissioning, each stage is completed methodically. 
Our air conditioning installation service is designed for homeowners seeking a practical way to manage temperatures throughout the year. The systems we install provide cooling in summer while also operating as efficient heating systems in winter. We offer wall-mounted, ducted and cassette solutions, install a range of established brands, and support every installation with a two-year workmanship guarantee. 
We install and replace unvented cylinders for households that need stronger water pressure and consistent hot water performance. These systems are particularly suitable where several bathrooms or outlets may be used concurrently. From assessing your requirements to selecting the cylinder, completing the installation and commissioning the controls, we manage each stage to support reliable operation.

I have used Thames Valley Heating & Plumbing many times and are very pleased with the service. They are prompt, respectful, clean, and tidy throughout the job. Nothing seemed too much trouble, and they took the time to make sure everything was talked through and completed perfectly. Going above and beyond. The pricing is very reasonable and clearly explained. I would happily recommend them to anyone looking for a reliable, friendly and trustworthy plumbing service.

Harry and his crew have been around 4 times for radiator installation, moving a radiator, a power flush, and replacing a leaking isolation valve. On the last one, they came to help with very little notice and extended their working day to make sure I didn't have a leak or have to have the water turned off overnight. With a 5 week old baby in the house this alleviated a lot of stress!
They are always on time. Always do a good job. Never any vibes of rushing off to other jobs. Never had to call them back for remedial work. And Always a pleasure to have in the house. Also good at providing advice on how to do jobs myself and how to maintain the system.
Thoroughly recommend Harry and his crew.

Extremely pleased with the service. Harry fixed a problem I had with my combi boiler (which a previous heating engineer had failed to do). Whats more, he was communicative, punctual, courteous, and followed up to ensure everything was working well.
I have already recommended him to other members of my family.

Team were punctual and did a brilliant job. Worked extremely clean wouldnt have even known theyd been in my house.

We have used Thames Valley Heating Services multiple times as they are really reliable, trustworthy and good value. Harry and his team were so efficient when they replaced our radiators in our new house, this was our first experience using their services. Always super professional and they made light work of the swap out, ensuring they were tidy when working - I hardly knew they were here. We have since called on them for all our plumbing and heating needs, always recommend them to all our friends and will continue to do so in the future.

Harry and Billy did a great job installing our new Worcester boiler and conducting a system flush. They were punctual, friendly and efficient and I felt confident in their work and the recommendations provided. Also at a reasonable price! I would certainly use Thames Valley Heating again in the future.

I contacted Harry late Sunday evening, with a leak under our kitchen island. Less than 24 hours later, Billy was round, working through all of the possible causes and managed to fix the problem there and then.
I couldnt recommend Thames Valley Heating Services enough and will be using them for all future works going forward!

Harry and Billy are my go to team for any plumbing and boiler needs i require. They were both involved in my complete home renovation repositioning and installing a new boiler with a hot water cylinder as well as re-piping and additional work required for under flooring heating across the whole ground floor. I also got them involved in another property to include a new radiator installation as well as general servicing of the boiler that was recently installed. I trust them completely and again are on speed dial should i need them. Photos attached of their work during my renovation.
