Tips for Improving your EPC Rating

There are many reasons to try and get the highest possible score on your EPC. The first is to try and ensure that your house is as energy efficient as possible. An energy efficient house costs less to run, saving you a potential fortune on your heating bills.

The other reasons are in terms of actually needing to achieve certain ratings. If you’re a landlord then your property MUST achieve an ‘E’ rating before you can rent it out. If you are looking for a Feed in Tariff (FiT) when you install a renewable energy product, then your property must already be ‘D’ rated.

Here are five top tips for improving your EPC score.

Insulation – The most important consideration can also be the cheapest too. Twenty five percent of a property’s heat is lost through its roof, luckily loft insulation is not only cheap, it is also one of the easiest things to install. Ensure you install it to a depth of 270mm (do not crush under boarding) in order to get the most benefit.Wall insulation is also crucial. Cavity wall insulation needs to be done by a professional company but it can be a relatively cheap process. Depending on government funding available to energy companies it can also be free.
Solid wall insulation can be very expensive but can also be the number one saver for energy bills in older houses.
Install renewable energy – If your home is suitable you should look into installing renewable energy. In almost all cases they will provide a large boost to your EPC score.Most people will think of solar panels when they imagine domestic renewables and Solar PV panels to supply electricity have been very popular. But you can also consider solar thermal panels for your hot water or biomass boilers or heat pumps to heat your home.
When improving your EPC, if you want your property to achieve maximum score then you MUST have some renewable energy in place.
Replace an old boiler – Heating makes up a large percentage of a household’s energy costs. If you have an old, inefficient boiler it will be reflected in your EPC score and, more importantly, it will be costing you more money than it should to heat your home.Look into getting an ‘A’ rated boiler and ensure that you have full control over the heating in your home. Also consider the installation of a room thermostat, a programmer and TRVs (thermostatic radiator valves.)
Get double glazing – If you have old, thin, single glazed windows with wooden frames then you shouldn’t be surprised to learn that a significant portion of the heat from your home is being lost through them.Get double or triple glazing installed. If it’s too expensive or it’s not possible, secondary glazing can be just as effective.
Replace your lightbulbs with LEDs – You can’t buy halogen bulbs anymore and there’s a good reason. Not only are they not energy efficient but they often only last a couple of years.Although replacing the bulbs will only have a small impact in improving your EPC and despite the fact that at first glance they seem expensive, when you learn that LED bulbs can last more than 20 years you realise that you’re actually going to save money.

Biggest EPC Wins

I often get asked as to what is the biggest win when it comes to an Energy Performance Certificate. What improvements can I make to my property which will improve its energy efficiency the most?

This is especially relevant to landlords nowadays who are bound by the regulations set out by MEES. Before you rent out a property to tenants, landlords must ensure that the property has a rating on an EPC of at least an ‘E’.

Landlords enquire about double glazing or cheap solutions like replacing bulbs with low energy alternatives. In truth both of these are pretty small fry in terms of improvements.

Boilers

Generally people want to avoid expensive improvements such as replacing boilers. In truth if the property has a gas boiler, unless it’s a very old floor standing gas boiler with an open flue, a change to a more modern boiler is unlikely to make a massive difference.

On the other hand, if the property is heated by electricity then the heating system could make a huge difference. If the property is old or exposed and it is heated by electric radiant heaters then the rating is going to be poor. In this case the recommendation will always be to upgrade to high heat retention storage heaters or fan assisted storage heaters. The difference in ratings can be huge and drag an ‘F’ or ‘G’ property into ‘D’ or ‘E’ straight away.

Insulation

But what of properties that aren’t electrically heated? The answer is simple. The biggest gains can come from simply insulating the property properly.

Loft insulation

If the property doesn’t have any loft insulation then add some. Any can make a difference but the recommended amount is to a depth of 270mm. Not crushed under floorboards. Putting boards on top of insulation makes it as effective as the depth it is crushed to.

This is a cheap and simple way to dramatically increase rating. It’s also an easy DIY job.

Wall insulation

The other vital insulation consideration is walls. This is especially important in pre 1930s houses with solid walls. This can be very expensive but is always very effective.

For houses with cavity walls it is a much simpler and cheaper solution but also very effective and can produce a significant difference to your EPC rating.

Energy Performance Certificates – What Does an Assessor do in Your House?

You know what an Energy Performance Certificate (EPC) is, but what exactly does an assessor do when they visit your house? If you call EPC Bromley to arrange an domestic energy assessment then what can you expect when they visit?

Have a look below for a summary of the items that EPC Bromley will consider during the assessment for your EPC.

House Age and Build Type

Working out the year that the house and any extensions were built will tell us what the building regulations were at that time and therefore how energy efficient the house is in general. A house built in 1930 would have had no insulation fitted to the walls as a regulation, this is not the case with a house built in 2010.

The build type (detached, terrace, flat) tells us where the heat may be escaping from. A detached house generally has at least four cold walls whereas a semi will have one shared wall which is warm. A flat could be heated from all sides and have a communal corridor area which is heated too.

Dimensions

Quite simply we measure the volume of your property. We need to know the amount of space you have to heat before we make a judgement on how you heat it. We’ll also consider whether you have a conservatory.

If your conservatory has an outside door sealing it off then it is discounted, if it is open plan then it is included and considered a source where heat can escape more easily.

Walls

Wall types are generally solid, cavity or timber framed and are as efficient as the regulations in place when they were built. Traditionally, solid walls without insulation were used on houses until well into the 1930s, this kind of wall is very inefficient.

If it is a cavity wall then we check whether the cavity has been filled with insulation retrospectively, as originally cavity walls were not filled.

Roofs

We poke our head into the loft and see whether it is insulated, if it has then how deep is it? Traditional insulation at the joists should be at least 270 mm deep. Remember, if you crush it down with floorboards to 100 mm then it is only 100 mm effective.

Floors

Are they solid or suspended floorboards, has it been insulated or do you have another dwelling below you?

Openings

We consider how many doors you have and whether those doors are insulated. We look at how much glazing you have and whether it is single, double or triple glazed. If it’s double glazed we consider what year it was installed, double glazing installed from 2002 onwards is much more efficient than glazing fitted before then.

If it was fitted before 2002 then we consider the frame type (metal, pic or wood) and the gap between the panes of glass.

We also look at how much draught proofing is in place.

Ventilation & Lighting

We look at how many fireplaces the property has and whether these are open, we also look for any mechanical ventilation or cooling systems that are in place.

We count the amount of light fittings and at the same time we count how many of these have low energy bulbs in place.

Heating Systems

How do you heat your home? If you use a traditional boiler then we consider how efficient that boiler is. Modern condensing boilers get the highest efficiency scores.

We consider how the heat is distributed (radiators, underfloor) and how that heat is controlled. Properties that have a room thermostat, thermostatic radiator valves and a heating timer will score highest.

If your property has more than one heating system then this is also considered as well as any secondary heaters such as a gas or electric fires in the reception rooms.

Water

How do you heat your water? Do you have a combination boiler or a hot water cylinder? If it’s a cylinder then how large is it? Is it insulated? Does it have a thermostat? We then consider how many bath/shower rooms are in the property, how many of these have baths, showers or both?

We also look at other options for water heating which may be in place. These include solar water heating, waster water heat recovery systems (WWHRS) and flue gas heat recovery systems (FGHRS).

New Technologies

We investigate if you have any other new technologies in place like solar photovoltaic panels or a wind turbine. The terrain you live in is considered(urban, suburban, rural) which determines whether a wind turbine would be suitable.

Checks are made at this point to see what type of electricity meter the property is has (dual or single charge). If the house isn’t heated by a gas boiler, we see whether there is a gas meter indicating it would be an option.

Any other info

Here’s where you can note whether the property has a swimming pool or uses a more obscure way to heat itself. For example micro CHP or a biofuel that isn’t listed in the usual database.

If you don’t understand some of these points, feel free to get in touch with EPC Bromley and ask. Otherwise your EPC Bromley assessor will be happy to answer any questions you may have whilst the survey is taking place.

Top Ten Tips for Better Home Energy Efficiency in Bromley

Read below for the top ten tips for energy efficiency in your home from EPC Bromley.

Replace light bulbs with LEDs – Gone are the days when energy efficient light bulbs made your light fittings look ugly and were as bright as a flickering candle. Modern LED spotlights, for example, are now bright enough to replace your halogens and they come in all shapes and sizes to fit any light fitting.

Control your heating – Your heating and hot water take up over half of your monthly fuel bills. Ensuring you have a heating programmer, a room thermostat and thermostatic radiator valves and using them effectively could save you a ton of money each year.

Draught proofing – Unless you have a particularly modern home you will be losing heat through gaps around doors and windows, or through the floorboards or chimney. DIY draught proofing can prove to be incredibly cheap.

Insulate your hot water tank – Your tank should have highly efficient foam insulation fitted around it. If it doesn’t, then purchase a hot water cylinder jacket. It’s far less efficient but better than nothing!

Wall insulation – Cavity wall insulation is efficient and cheap (sometimes free!). If you need solid wall insulation then it is far more expensive, but will save you hundreds of pounds in heating bills each year.

Ensure you have double glazing – Double glazing fitted after 2002 is far more efficient than before. If you are unable to install double glazing then secondary glazing can be just as effective.

Loft insulation – Very important, if you have no loft insulation at all then this will seriously affect the energy efficiency of your house. Remember, the recommended minimum depth is 270 mm. If you place floorboards over the top of insulation it is only as effective as the depth it is squashed to.

Use your shower rather than a bath – Showers use far less water than a bath, therefore your boiler is working less time to heat the water.

Install solar energy – Solar thermal panels for hot water and Solar PV panels for electricity will not only make your home more energy efficient, but they will also save you a lot of money. If you live in a rural area it is also worth considering a wind turbine.

Track your energy usage – Energy monitors help you to keep an eye on how much energy you are using. Most energy providers will be able to supply you with one.
