Q: What is the average cost to install a boiler?
A: The cost to install a new boiler in the UK typically ranges from £2,000 to £5,000, depending on the boiler type, size, and whether it’s a straightforward replacement or a full system upgrade.
At EHS, we offer competitive, transparent pricing and up to 10-year guarantees on selected boilers. We also understand a new boiler can be an unexpected cost, so we provide our customers the flexibility to spread the cost with our finance options.
Q: What is the cheapest way to get a new boiler?
A: The most cost-effective route is to choose a reliable, energy-efficient model and take advantage of any manufacturer offers, finance plans, or grants available.
EHS offers affordable finance options and can guide you through available schemes so you get the best deal without cutting corners on quality.
Q: Who qualifies for a boiler grant?
A: Boiler grants are typically available under the Government’s ECO4 scheme to households on certain benefits or with low incomes, especially if the home is energy inefficient.
EHS can help check your eligibility and assist with the application process.
Q: Which is the best boiler in the UK?
A: Leading brands like Worcester Bosch, Vaillant, and Ideal consistently rate highly for efficiency, reliability, and warranty length. The “best” boiler for you depends on your home size, hot water demand, and budget.
We’ll recommend the perfect model during your free EHS survey.
Q: Does home insurance cover boiler replacement?
A: Most standard home insurance policies do not cover boiler replacement unless it’s due to an insured event like a fire or flood.
Some policies offer optional boiler cover, but it’s worth checking the small print.
Q: Are combi boilers being phased out?
A: No, combi boilers are not currently being phased out. However, future energy policies may encourage alternatives such as heat pumps.
For now, combi boilers remain a highly efficient and popular choice for UK homes.
Q: What is power flushing?
A: Power flushing is a process where a specialist machine circulates cleaning chemicals through your heating system to remove sludge, rust, and debris.
This improves efficiency, extends the life of your boiler, and helps radiators heat evenly.
Q: Is power flushing worth it?
A: Yes — if your heating system has cold spots, noisy radiators, or slow heating, a power flush can restore efficiency, lower bills, and prevent costly breakdowns.
Q: Do I need a power flush with a new boiler?
A: Most boiler manufacturers require a system flush before installation to protect the new boiler and maintain warranty validity.
At EHS, we include a system flush with every new installation.
Q: Do you need access to all radiators for a power flush?
A: Yes, to get the best results we need access to every radiator in the property so we can flush the system thoroughly.
Q: What are the risks of a power flush?
A: If your system is very old or poorly maintained, power flushing can reveal weak spots in pipework or radiators.
However, our experienced engineers assess your system beforehand to minimise any risk.
Q: How do I know I need a power flush?
A: Signs include:
Cold patches on radiators, noisy pipes, slow heating, frequent boiler breakdowns, or dirty water when bleeding radiators.

A: Yes — boilers are a key part of a gas engineer’s work, including installation, servicing, and repairs.

Q: Do gas engineers check radiators?
A: Yes — during boiler servicing or heating system work, engineers will often check radiators for issues such as cold spots or trapped air.

Q: How often should your boiler be serviced?

A: It can become unsafe, less efficient, more prone to breakdown, and may invalidate your warranty.
Q: What is the daily checklist for a boiler?
A: Most homeowners don’t need a daily checklist, but it’s wise to check your pressure gauge occasionally, listen for unusual noises, and ensure there are no leaks.
Q: Can I service my boiler?
A: No — only a Gas Safe registered engineer should service your boiler. DIY work on gas appliances is illegal and dangerous.
At EHS, our engineers are Gas Safe registered and prioritise the safety of our customers, their family and their home.

A: Typically 30–60 minutes, depending on the boiler type and condition.
