Biomass Servicing Standard

MCS 040 Biomass Servicing Standard

Under the new MCS040 standard, to continue to receive RHI payments, your boiler must be serviced by an service provider that is MCS 040 accredited.

MCS work with the industry to maintain and improve the quality of installers and service providers so people can have confidence in the low carbon technology they invest in.

All biomass boiler services carried out by NerG comply with MCS 040 standards, these recognise competent maintenance companies that can carry out the services necessary as specified by biomass boiler manufacturers. You can be assured that your boiler is in safe hands with us.

We can provide routine and reactive maintenance for biomass boilers, their feed systems and we can sweep chimneys up to 80m tall. We primarily service commercial biomass boilers but can also service larger domestic biomass boilers too.

Our engineers are trained and experienced in servicing most makes and models of boilers. Contact us for more details.

Why Service Biomass Boilers?

It makes financial sense as an owner of a biomass boiler to have it serviced regularly. A biomass boiler that isn’t cleaned and maintained regularly will not run as efficiently. Therefore, the money you spend on wood fuel will be wasted, as it is not turned into heat which you can use.

In addition, the Renewable Heat Incentive (RHI) only pays for the heat that is output from the boiler as hot water, there is no payment for the heat lost up the flue or for inefficient burning of the wood fuel.


NerG’s Approach

NerG’s approach to servicing is very simple. If you’ve got a problem, we’ll fix it and if you want a routine service, we will happily book you in and carry it out. Our pricing is also simple, we charge for the time it takes us to do the service.

If you have your servicing carried out by us and buy any replacement parts through us, we are quite happy providing telephone support and advice free of charge.

We think that seems a fair swap?


Contract Vs No Contract

We have chosen not to go down the route of trying to tie everyone into maintenance contracts, preferring to work on the premise that if you think we’ve done a great job you’ll use us again.

That said, many of our customers such as housing associations, poultry producers, glasshouse nurseries and large factories prefer us to be contracted.

Obviously we are happy with this too.
