We’ll also top up the pressure, inspect the pipework, test the shunt pumps and any other directly related components for signs of leakage or wear.

Boiler Installation FAQs

Your questions about boiler installations answered

The cost of a new boiler largely depends on the size and type of boiler you want installed and the specifications it needs to meet. New boilers can cost anywhere between £500 and £3,000 for a standard domestic system, the installation cost is then based off how long it will take to install the boiler. Our hourly rates for an engineer in working hours (weekdays between 9am and 5pm) are £175 per hour, per engineer and our day rates are £1100 for one engineer and £1800 for two. If out of hours (5pm – 9pm on weekdays, weekends and holidays) work is required the rate is £250 per hour, per engineer. The cost of the boiler can go above £3,000 if your property requires a larger output than a singular boiler can provide as a cascade system using multiple boilers will have to be implemented. The cost can also increase if you require other equipment on top of your boiler e.g. BMS, gas burners, gas booster pumps and gas interlock systems.

If the boiler is gas-fired then it is a legal requirement for a Gas Safe registered engineer with the correct qualifications to install the boiler. If the boiler is LPG or Oil they will also need to have the correct certification and qualifications e.g. an OFTEC certified engineer. If the boiler is electric and domestic as well as not rented then you can technically install your own electric boiler but this is not recommended for safety reasons. You may also need to have the boiler reinstalled by a qualified engineer if you plan on selling or renting out the property.

If you are strictly talking about a new boiler and not a new heating system, then there will generally only be a slight increase to the value added to the property. If you install a new heating system including all new radiators and pipework, the increase will be much greater but by comparison, a heating system will not increase the value as much as a loft conversion so the increase in value needs to be relative to the amount you are investing in the heating system. You also need to consider the existing boiler in the property, as if the boiler being replaced is really old then obviously the value will increase further. There are varying arguments for the exact amount a new boiler will increase your property’s value by, with most saying around 4% or £8000 for a £2000 – £3000 boiler installation but again this is dependent on many different factors. If you are selling your property and the boiler is not functioning correctly or is considerably old, we recommend a replacement to not add further complications in relation to selling your property.

Depending on the efficiency of a boiler installed and the boiler it is replacing, you can expect to save up to 30% on your energy bill. Most new boilers have an efficiency rating above 90%, whereas older boilers were around 60 – 70%; look out for the term A-rated as this means that the boiler does in fact have an efficiency rating above 90%. If the boiler you are replacing already has a high efficiency level then it is unlikely you will see a drastic reduction in your bills, as it will not use less fuel if the efficiency is already at a high level. Another benefit of replacing an old boiler with a new one is the amount of carbon produced, a new boiler will significantly reduce your carbon footprint especially if the boiler being replaced is 10 years or older.

Most gas boilers on the market today will be able to run on a mix of 80% natural gas and 20% methane, although we do recommend checking with the manufacturer beforehand to be certain. Many gas boilers will also be able to be easily converted to run on 100% hydrogen, with the main issue being the availability of hydrogen. Natural gas is readily available across most of the country by the natural gas grid in the UK, whereas hydrogen as a fuel source doesn’t have this infrastructure in place. So despite your gas boiler most likely being able to run on hydrogen sourcing the fuel is a different story entirely.

Gas boilers can still legally be installed, the reason people think this isn’t the case is due to proposed legislation that detailed banning gas boilers from being installed in new build homes from 2025. This legislation has not been passed and therefore isn’t official but even if it does pass this only affects new build homes, meaning that older homes will still be able to have their existing gas boilers replaced with new gas boilers. For more detailed information on the topic please read our article.

Electric boilers can actually be the most expensive type of boiler to run. As of  2022, the price of electricity is on average around £0.20 – £0.30 per kWh, whereas natural gas is £0.04 – £0.5 per kWh, LPG on average is £0.07 – £0.08 per kWh and oil is £0.05 – £0.06 per kWh. So despite electric boilers normally being more efficient than other types of boilers, it doesn’t make up for the price of the energy being more than 3x the amount than the fuel used in other types of boilers. On the other hand if you use a renewable means of generating electricity then the costs can be significantly cheaper.

Electric boilers are more efficient than gas. Electric boilers normally have 99% – 100% efficiency, whereas new gas boilers have an efficiency rating around 90% – 95%. This is because the electricity used by an electric boiler is converted to heat straight away which heats the water but gas boilers lose some of the heat in the combustion process by heat dissipation. So yes, electric boilers are more efficient than gas but not by much, especially with the technology of gas boilers constantly improving.

Yes, LPG boilers need to have a gas safety check performed annually just like natural gas boilers. This is a legal requirement for all commercial properties and leased properties, it also needs to be performed by a gas engineer with the correct qualifications to work on LPG boilers.

The efficiency of LPG boilers can vary depending on the model and brand. Generally, modern LPG boilers are designed to be highly efficient, on average most achieve around 90% efficiency. However, this level of efficiency is always increasing due to technology and energy developments.
