New Boiler Installations Harpenden
PHP Services provides professional boiler installation services throughout Harpenden, supplying and fitting high-efficiency combi, system and regular boilers from leading manufacturers. Our experienced Gas Safe engineers will recommend the most suitable boiler for your home, heating requirements and budget.
Older non-condensing boilers can waste a significant amount of energy. Modern condensing boilers are designed to operate far more efficiently, helping to reduce energy consumption and lower heating bills.
You should be aware that current building regulations state that any replacement or new gas-fired boiler must be a condensing boiler. Older boilers convert as little as 60% of the fuel they use into heat, which can have a significant impact on both your heating bills and the environment.
We specialise in the installation of SEDBUK A-rated condensing boilers and renewable energy products from Worcester Bosch, using the latest technology available. Modern condensing boilers can achieve efficiency levels of over 90%, potentially reducing annual heating costs by 30% or more compared to older systems.
Depending on your heating and hot water demand, there are different types of condensing boilers available. Our engineers can help you choose the most suitable option for your property and lifestyle.

What happens on the day of your installation?
We always aim to arrive at the property at the agreed time, usually 8am. The first thing our team will do is apply carpet protectors and cover surface areas with dust sheets to ensure your home is well looked after during the installation.
The water and gas will be isolated to allow us to remove your existing boiler. This means that during the installation there will be no running water, so be sure to fill the kettle before we arrive.
Being environmentally conscious, we will take away all debris and packaging and recycle as much as possible, leaving your home just as neat and tidy as we found it — only a little cosier thanks to your new boiler.
Once your new boiler has been installed, we will complete the registration with Gas Safe / Oftec and with Worcester Bosch.

What our customers say about
PHP Services
My boiler was declared beyond repair in December 2025. I contacted PHP. They came out the same day to review the boiler, quoted the following day and a new boiler was installed a few days later. Matt, the installer, was reliable, tidy in the workspace, friendly and generally did an amazing job, including showing me boiler features on completion. Very happy with service from start to finish.
