There are many boiler manufacturers; Worcester, Vaillant, Gloworm, Wieissman, Ariston, Potterton, Ideal, Baxi and Vokera to name quite a few.
Each manufacturer has a range of boilers to meet specific requirements and budgets. As with, for example, cars the more power and functions the model has the more it will cost and, of course, some brands cost more than others.
For a Worcester Gas Combination Boiler with an output of 24Kw (suitable for a flat with 1 bathroom and 8 – 10 radiators) you could pay £1,200 (Inc VAT), where as a Vokera boiler with similar output may cost as little as £500 (inc VAT).
As the saying goes, you get what you pay for. Generally cheaper boilers will be less efficient (burn more Gas), require more regular maintenance, have a shorter warranty period and have a shorter life expectancy. As well as having less functionality. What is being replaced?
Replacing an existing gas condensing boiler with a new one in the same position is likely to require the least time to do and therefore be a relatively low labour charge (£700 - £1,000) compared to, say, a heat only gas boiler being changed to a gas combination condensing boiler which may have a labour charge of £1,600 to £2,000.
As regulations and technologies have upgraded so the position of an existing boiler may not be suitable for a new boiler, the route a flue takes may no longer allow access for visual inspections or the pipe work (Gas and Water) leading too or from a boiler may need re-routing or replacing. All these will take time and materials to alter and upgrade and therefore affect the cost. Costs for additional trades.
Aside from simply replacing the boiler there may be other trades required.
- A joiner to box in pipe work, tidy up a cupboard or fit flue inspection hatches
- A roofer if the flue is to now exit through a roof
- A Decorator to make good any areas of wall where the old boiler was removed, pipes were re routed or to paint new pipe boxing.
- A “core cutter” to core a hole through a wall for a flue exit point.
- An electrician to run a new power source to the boilerOther potential charges and costs
And finally, other tasks that may need completing when installing a new boiler:
- A power flush
to find out more about power flushing) may be needed for older systems where there is a build up of sludge. Some boiler manufacturers make it a condition of their warranty that a power flush is carried out at the time their boiler is installed. Cost £350 to £500.
- Installing a magnetic filter
will help prevent the build up of sludge and ensure more efficient running and longer life of a new boiler. Filters will cost from around £100 to £180 and take around an hour to install, though your gas safe engineer may do this as part of the installation price.
- Thermostatic Radiator Valves
(TVRs): adding these to your system gives more control and potentially reduces running costs. A valve itself will cost from £7 to £60 or more.
- Thermostatic Controls:
This is the central control panel from where the temperature of the system can be controlled. Again the cost of these varies widely depending on the functionality required; the most recent innovation in these controls being the use of smart phone apps to remotely control the heating. Costs range from £50 to £250 and more.
