"Huge difference to our energy bills!"
We had an air source heat pump installed earlier this year by Tag Renewables, and we couldn't be happier. The house stays warm and comfortable even on colder days, and we’ve already noticed a big drop in our energy bills. It’s also reassuring to know we're using a more environmentally friendly system. The installation was smooth, and the team were professional from start to finish. Highly recommend making the switch!

"Outstanding service from start to finish!"
We recently had an air source heat pump installed by Tag Renewables and I can't praise the team enough. From the initial quote to the final handover, they were professional, knowledgeable, and genuinely helpful. They took the time to explain everything clearly and made the whole process stress-free. The system works brilliantly, and it's clear these guys really know what they’re doing. If you're thinking about going renewable, don’t go anywhere else — Tag Renewables are the best in the business!

Frequently Asked Questions

What’s the difference between a gas boiler and an oil boiler?

Gas boilers use natural gas from the mains supply, while oil boilers rely on stored heating oil, typically delivered by truck. Oil boilers are often used in rural areas without access to the gas grid.

How long does a gas or oil boiler installation take?

Most standard boiler installations take 1 to 3 days. The duration depends on the complexity of the job, such as whether it’s a like-for-like replacement or a full system upgrade.

Do I need planning permission to install a new boiler?

In most cases, no. Installing or replacing a boiler in the same location does not usually require planning permission. However, listed buildings or major relocations may have special requirements.

How often should a gas or oil boiler be serviced?

Both gas and oil boilers should be serviced annually by a qualified engineer to ensure safe and efficient operation and to maintain warranty coverage.

What size boiler do I need for my home?

The right boiler size depends on the number of radiators, bathrooms, and the overall heating demands of your home. A professional installer will calculate your needs to recommend the ideal model.

Are modern boilers more energy efficient?

Yes. Modern gas and oil boilers are condensing units that can achieve efficiencies of over 90%, significantly reducing energy bills and carbon emissions compared to older systems.
