This is where we differ from many competitors and will not, in any case, carry out poor workmanship and/or cut corners to win against our competitors or to earn more money, we find this sometimes losses us work on new customers, those finding cheaper quotes and some not aware of the regulations the law holds. but I have a saying and In which I value very strongly ' I do a job properly and to legislation or not al all' and 'you will always find cheaper out there but will it be the same standards'. I have very competitive charges but only when comparing on like for like basis, for example, very typically when installing a new combi gas boiler is it a requirement to install limescale protection when in hard water areas, around 9 out of 10 installations 

we come across do not have this.

In reality this makes my quote £40 dearer alone just on this device over someone who is not providing the correct installation methods and that's one example out of 100's. 

The best advice I can give customers when deciding who to choose for there project is, do not just look at the price, always check what you are being quoted on and ask for references 

or previous works if necessary.
