How to improve the energy performance of your property


From April 2018 all landlords must adhere to revised criteria regarding energy efficiency and as this will be a legal requirement Chantries has teamed up with energy assessor Gary Ryan to help give the right advice and make the changes as easy as possible.


Gary is also offering a consultancy service to ensure the best ratings are achieved with as little investment as possible from landlords so please contact him on to arrange a meeting.


Here, he highlights the main ways landlords can meet the new legal requirements:


Construction – Solid brick properties and properties heated by means other than mains gas boilers are likely to fall into the F and G categories making them illegal to let.


Heating – In properties with electric room heaters/ceiling/electric under floor heating changing to new style storage radiators will have a positive impact – it’s important that a ‘multi/dual rate economy 7’ type electric meter is installed in order to take advantage of the cheaper overnight tariff - this improves the efficiency (cost) of the heating hence an improvement to the EPC ratings.


Increase your loft insulation – This is one of the easiest and cheapest ways to improve your EPC rating.


Cavity wall insulation – If you have cavity walls, insulating a cavity can improve the rating by 5-10 points on average.


Upgrade your heating – The heating system is one of the key factors in the EPC. If you have an old boiler, upgrading to a new condensing model will improve your rating.


Insulate your hot water cylinder – Not everyone has a hot water cylinder, but if you do, it is worth adding insulation to the tank. This is cheap and easy to do.


Glazing – If you have single glazed windows, upgrading to new double-glazing will improve the rating – not as much as wall and loft insulation, but still an increase.


Documentation – If you have already had insulation installed, or if you think there may be insulation from a previous occupier, but there is no access to the space, then you should try to get documentation to show this to the EPC assessor. Sometimes this can make as much difference as actually installing an improvement. The same goes for windows installations and other improvements.


Seal open chimneys – Open fires and draughty chimneys actually make some difference to the EPC rating. If possible, block these up permanently, or install a closed heater in the opening to add a few further points of improvement.


Solid wall insulation – If the property has solid walls, the EPC rating is going to be much lower than an equivalent cavity wall property. You can either insulate internally or externally with a solid wall, but either way it is expensive. The good news is that it can increase the rating of the property by 10-20 points or more.


Renewables – Adding solar PV should boost your rating, dependent on the size of the system being installed. With larger 16 panel systems, you could add 10 points to the rating. Solar thermal, although usually a bit cheaper than a PV system, will only add a few points to the rating.


Lighting and draught proofing – Adding draught proofing and changing your lights over to energy efficient versions can add about a point each onto the final rating. Not much, but they don’t cost much to do!
