Should we find issues with your existing system these will be brought to your immediate attention and a quote for any additional work because of these findings will be given.

When asbestos is removed, you will need to produce a “site clearance for reoccupation” certificate, which you can get from the asbestos removal company, before we continue to work at your property.
19.The price we quote includes removing all non-dangerous materials, including your old boiler and central heating parts we replace.
20.The Contract price quoted is subject to any changes in Value Added Tax.
21.Our engineers may need to gain access to the property main or garage roof – if a vertical flue is installed, condensation pipe coming from loft etc. GWE Southern Ltd and our engineers will be as careful as is practically possible but do not hold any liability for damage to a roof if we have to gain access.
22.When brickwork, stonework or other masonry has to be made good e.g. Original flue position from old boiler, we require the client to provide the necessary bricks required for making good, with the correct quantity allowed for. GWE Southern Ltd will not provide the bricks for these works unless specifically outlined in the quotation provided in the quotation.
23.On the day of completion, should our engineer not be able to commission the new boiler fitted by GWE Southern Ltd, due to an existing problem with the system, including: valves, controls, electrics and gas, a commissioning charge of £110 plus VAT will be applicable. A GWE Southern Ltd engineer will need to revisit the property in order to commission the boiler.
24.Unless it is otherwise stated in the quotation and schedule of works, GWE Southern Ltd will connect onto your home’s existing electrical system. If the boiler location is changed as part of the schedule of works, then a new fused spur may be required. This quotation does not include the installation of a new fused spur, unless specifically stated. In the event that there is no fused spur present, the boiler will be commissioned on a temporary supply and it will be the home-owner’s responsibly to upgrade the electrical supply to meet current regulations.
25.If the boiler is to be installed in the loft or at another high location, it is the customers responsibility to install any relevant accessibility parts such as fixed loft ladder, lights, fixed surface/platform, hand rails etc as to conform to current building regulations.


As part of responsibility as Gas Safe Registered engineers, we are required to connect any gas appliance to a gas supply that is safe and sound. Consequently we will need to carry out a gas soundness test on the first of the installation of any new boiler or heating system.
Should be any leak or defect within the existing gas pipe work we would have no alternative but to condemn the supply, or take steps to make the supply safe as necessary or re-pipe the supply prior to the installation work being carried out. Although a rare occurrence, any such work is totally unforeseen and may have to be an extra amount to that shown in the quotation. The cold water flow rate shown in the quotation is measured using a flow measuring device in litres per minute at the time of the initial visit by our Sales Advisor. Flow rates can fluctuate depending on the age and condition of the water supply and the time of day the reading is taken. When brickwork, stonework or other masonry has to made good e.g .Original flue position from old boiler, we are unable to provide a match for the existing materials due to restrictions on availability and effects of weathering over the years. Whenever possible we will endeavour to provide a similar finish. Should a Customer wish to provide his/hers own materials for matching purposes, we will make allowance in the calculations of the price agreed in the quotation.
