How can I get a good BER Rating?

Find a good BER Assessor

The assessor must be prepared to spend time looking for details which could improve your rating, such as examining which heating pipes are controlled by which thermostat or measuring the thickness of the air gap in double glazed windows, otherwise you will be credited with "default" measurements which are invariably not as good.

Attend to the following before we visit to survey the property;

  1. Fit a lagging jacket to the hot water cylinder. If the jacket is less than 80 mm thick you can put another on top of the original.
  2. Replace as many light bulbs as possible with CFL or LED low energy bulbs. Outdoor lighting and plug- in table lamps however are not counted for BER assessment.
  3. If you have had any upgrade work done on the property since it was built, try to locate the original documentation and have it ready to show the assessor. This can be used as proof that certain improved specifications are in place even when they are no longer detectable. Extensions, new windows, attic room conversions, and wall insulation are common instances of where such documentation can be useful. Planning permission can be useful to prove that an extension is modern, in which case the default asumption is that it has been insulated as per the standard practice of the era (and not as per the era of the original house). Any paperwork relating to building work done, or to new windows, should include the address of the property being assessed. If internal wall insulation boards (warmboards) have been retrofitted to the property as a DIY project, the documentation might consist of a delivery docket or an invoice from a builder's merchant, but it must show the relevant address and also a sufficient quantity of material to account for all the walls that have been insulated. If there is no documentation available, you can still prove the presence of the insulation by drilling a small hole of 25mm in each exposed facade of the house, so that the assessor can measure the insulation thickness. The BER survey does not include invasive methods, but the assessor can advise you on where to drill any such holes, if you want to drill them. A typical semi-detached house would have three exposed facades for this purpose, and a typical detached house would have four. If on the other hand, the internal insulation cannot be verified (either as a whole, or on any particular facade) then the whole facade will be treated as if it was "dry lined". Dry lining is when a  sheet of plasterboard is fixed onto a wall on wooden battens, or on dabs of wet plaster. Although there is no polyurethane insulation on the back of the boards as there would be with IWI warmboards, there is still some insulation value from the layer of trapped air (being the thickness of the timber battens or the plaster dabs) A "drylined" wall is therefore considered better than an unimproved wall for the purposes of the BER Cert, but not as good as a wall with added IWI.
  4. Anything that can be seen, measured, and photographed by the assessor will be certified as part of the BER process. This includes the insulation in accessible attics, any new central heating boiler, the various heating controls, and the hot water cylinder etc. Sometimes old photographs taken by the householder during a renovation can be of help, but unfortunately they tend not to be detailed enough to show the type or thickness of any insulation used. In regard to windows, we always measure  the gap between the two panes of double glazed units (it can be anywhere from 4mm to 24mm - wider is better) and we also check for the presence of Low-E coating. This special coating allows heat from the sun to pass through the glass, but inhibits any heat radiating back out from the room in the opposite direction. So even if you have no documentation for your windows, their type and characteristics can still be assessed to a high degree of accuracy during the survey, which will have an appropriate impact on the BER Cert.
