What we do Somerset West Home Energy can help you make your home more comfortable and cheaper to heat at no upfront cost to you. We can help you access funding for solid wall insulation a measure that increases the thermal performance of buildings and could improve the value of your home. The funding is available from Scottish and Southern Energy and from the three district councils of West Somerset, Taunton Deane and Sedgemoor And for the cases where grants aren’t available or don’t cover the full cost of the installation we have a ‘pay-as-you-save’ option. This is a finance package developed with our partners Wessex Home Improvement Loans that allows you to use the savings you enjoy as a result of the energy efficiency improvements to cover the price of the installation. This means you have a warmer home without worrying about the cost. Contents p4

How does the service work? Here’s a simple seven-step guide to the Somerset West Home Energy service. Our team of experienced energy advisors are on hand should you wish to contact us at any time.

1) The first step is to register your interest in the scheme by contacting the Home Energy Team at the Centre for Sustainable Energy on 0800 082 2234 or [email protected]. We’ll give you more detailed information about how the scheme works and run through some initial questions. 2) If you decide to proceed, your details will be passed on to a Domestic Energy Assessor (DEA) who will contact you to arrange a suitable time to undertake a survey at your home in order to produce an Energy Performance Certificate (see opposite).

3) The completed Energy Performance Certificate will be sent to the Somerset West Home Energy team. It will outline the possible improvements that could be made to your home and the savings that could be made on your fuel bill. 4) Based on this information the team will calculate the potential grant funding you could access. An application form will be sent to you, along with all the details of your anticipated grant allowance and options for pay-as-you-save finance through Wessex Home Improvement Loans (www.wessexhil.co.uk)

Centre for Sustainable Energy Home Energy Team phone 0800 082 2234 email [email protected] web www.cse.org.uk/advice 4 | Somerset West Home Energy

5) This application form needs to be completed by you and returned to us, along with a copy of the quote you want to proceed with from an approved installer (see pages 14 to 20). We strongly recommend that you seek quotes from at least three installers. 6) The Somerset West Home Energy team will provide final confirmation of your grant allowance. You have 3 months to return a completion certificate and a copy of the invoice. (In some circumstances this deadline may need to be extended. Any extension will always need to be authorised by the Somerset West Home Energy team). 7) We will check the paperwork and pay the grant directly into your bank account. You should check your installer’s payment terms to ensure they are happy for you to pay them when you have received the grant, so you don’t have an upfront cost.

The Energy Performance Certificate (EPC) By insulating your solid walls you will improve the efficiency of your home and reduce the amount of fuel you need to use to heat it. Lowering your fuel usage also reduces your carbon (CO2) emissions. The actual savings can vary but as a guideline, you can expect to save between £365 and £385 a year on your fuel bills*. This depends on the type and size of property you live in, your heating system and the insulation material used to improve the efficiency of your home. Somerset West Home Energy offers a free survey by a Domestic Energy Assessor (DEA) who will provide an Energy Performance Certificate (EPC) for your home. The information provided in the EPC will allow the Somerset West Home Energy team to calculate your potential fuel bill and CO2 savings from making improvements to your home. The grant which can be accessed is calculated from this data so all of this information will be passed on to you in your application paperwork after the survey is completed.

Pay as you save As we won’t be able to access funding to cover the whole cost of insulating your solid walls, you may wish to consider a flexible finance option through our partnership with Wessex Home Improvement Loans. Wessex Home Improvement Loans already work closely with your local council to provide homeowners with finance for home improvements and repairs.

We have devised this arrangement based on the principle of ‘pay as you save’ – this means that your repayments are linked to the expected savings you will make on your fuel bill by having solid wall insulation installed. For example, if the EPC anticipates your fuel bill savings to be £30 per month the loan repayments would not exceed this amount. Finance can be offered at an interest rate of 6.5% (Typical 7.2% APR) and repayment periods can be flexible. By using this innovative finance mechanism you can consider yourself a trailblazer as the Government’s Green Deal, due to launch in late 2012, will work along similar lines. If you would like to find out more, please contact us and we can put you in touch with the team at Wessex Home Improvement Loans.

Grant conditions Somerset West Home Energy can only access funding for whole-house solid wall insulation installations. If you wish to insulate only part of your property, we are unable to help. It is also worth noting that park homes and mobile homes are not eligible for financial assistance. As a condition of the funding, your walls must achieve a U-value of 0.3 or less (as required by current building regulations) once they have been insulated. Check with your chosen installer to make sure your home can achieve this before going ahead.

What type of work will the funding cover? Somerset West Home Energy assists people with insulating their homes; other home improvements are not covered unless they are directly related to the installation of the insulation. See right for examples of works which are considered eligible or not eligible. Every property is different and it is therefore impossible to come up with a definitive list. So if you are concerned about the eligibility of your installation, please contact us so that we can clarify the position before any work begins.

Eligible works Installation of insulation – to include the whole ‘system’ – that is the insulation itself and all adhesives, fixings, membrane and render coats/plaster/cladding where applicable. • Moving or re-installing ancillary items as a result of the additional insulation depth (e.g. guttering, light switches, plug sockets, radiators, skirting boards) • Reinstating existing exterior finish (e.g. pebble dash) • Maintenance of existing external services where change is required due to insulation works (e.g. phone line, TV, gas, Sky dish etc) • Planning permission costs for associated insulation work • Scaffolding required for insulation works

Ineligible works • New kitchen installations • Window or door replacement • New carpets or flooring finishes

Before and after ... This Victorian terraced house now benefits from external solid wall insulation that will not only make it more comfortable, but has transformed the appearance of the home from the rear as well.


An introduction to solid wall insulation Nearly half of the warmth in some solidwalled houses escapes through the walls. By insulating these walls we can slow down the rate at which heat is lost and keep the warmth inside the home for longer. Solid wall insulation makes homes more comfortable and cheaper to heat. It works by adding to the walls a layer of material that acts like a thermal blanket. Solid walls can be insulated internally (from the inside) and externally (from the outside). Both are significant undertakings in terms of cost and disruption – and external solid-wall insulation is most definitely not a DIY task. But both options can make your home warmer and greatly reduce your heating bills at the same time.

How do I know if my home has solid walls? If your home is made of brick, and the bricks have an alternating long-short-long pattern (top diagram), then the walls are likely to be solid. If you can see only the long edge of the bricks (bottom diagram), then the wall is almost certainly a cavity wall.

Solid wall

Cavity wall

Of course, if the brick work isn’t visible this might be difficult. However, measuring the thickness of the wall at any entrance or window might help. A solid brick wall is usually about 22 cm thick, a cavity wall between 27 cm and 30 cm thick, and a solid stone wall could be as much as 50 cm. The age of your home is also a fairly good indicator. As a general rule, if it was built before the 1920s, it’s unlikely to have a cavity. Solid wall insulation may be suitable for a variety of property types such as brick, stone, steel-framed and concrete construction.


External solid wall insulation External solid wall insulation involves adding a layer of insulating material to the outside walls of a building and coating this with a protective render or cladding. There are lots of options to create the finish that you want and these may add value to your home. It’s a specialist job that requires approved installers working to a specific tried and tested system. There’s a list of these on page 14. External solid wall insulation may be particularly suitable if you wish to avoid internal disruption or are doing other work to the exterior of your property, such as re-rendering.

Changes to the external appearance External solid wall insulation won’t affect the size of your rooms but you might need planning permission as it could change the appearance of the building. There is a huge array of colours and finishes that can be applied to solid wall insulation, and all the options can be discussed with your chosen contractor. Often the existing finish can be replicated to preserve much of the original appearance of the house, but you may still need to apply for planning permission (see p21 for more details).

Average costs Externally insulating your home costs on average £9,000 to £13,500*, though this obviously depends on the size of the building and the number of outside walls being insulated. It is likely to be more expensive than internal wall insulation because of the higher material, labour and overhead costs.

Disruption External solid wall insulation is a significant undertaking that inevitably involves a degree of disruption, examples of which are listed below. Note that this is a guide only; you should discuss issues that may arise with your contractor. • Garden access may be required and boundary walls and lean-to structures may need to be adapted • Scaffolding may need to be erected, and a space found for a skip and material storage • External fittings like rainwater pipes, satellite dishes and phone and power cables may need to be removed (though normally without interrupting the service) and replaced afterwards • Contractors will require water and power, and possibly the use of a toilet • There will be a lot of noise, including power tools • The work will generate a lot of dust and grit

External solid wall insulation: an example The model below shows a cut-away of external solid wall insulation applied to a noncavity brick wall. This kind of wall is common among houses built between around 1880 and the mid-1920s.

1

Insulation board

This is the layer of insulation that will slow the lost of heat from inside the house. It is attached to the external wall, either with an adhesive or mechanical fixings and protects and extends the life of your brickwork.

2

4

Window sill

External fittings such as pipework and satellite dishes may need to be removed before insulation is applied. It may be necessary to remove and extend window sills so they protrude beyond the cladding.

5

Window and frame

Windows can change in appearance, as the insulation needs to extend into the window recess.

Middle section

This section, composed of a mesh between two thin layers of render, adds strength and rigidity.

5 3

Top layer

A final coating of cladding or render is applied to give the wall the required appearance. It brings the total thickness of the added material to between 50 and 125 mm.

Internal solid wall insulation Internal solid wall insulation is particularly appropriate in cases where maintaining the external appearance of the building is important. There are several types of internal solid wall insulation, with the types eligible for support from Somerset West Home Energy falling into two categories: 1) Rigid insulation boards (see picture opposite). These come in varying thicknesses up to 10 cm and deliver the highest energy saving. Some have pre-attached plasterboard to speed up the installation process. 2) Alternatively, battens can be fixed to the wall, in-filled with insulation and covered with plasterboard. This is a good option if the wall has a lot of heavy fittings such as book cases or kitchen cupboards.

Average costs Internally insulating your home will probably cost between £5,500 and £8,500*, depending on how many rooms are being renovated. Generally this is less expensive than external solid wall insulation because of the lower material, labour and overhead costs it involves.

Room space Internally insulating your walls will slightly reduce the size of your rooms, although many people report that by making a cold wall warmer they actually find that they have higher proportion of usable space in the room.

Disruption Internal solid wall insulation is a significant undertaking that inevitably involves a degree of disruption, examples of which are listed below. Note that this is a guide only; you should discuss issues that may arise with your contractor. • A skip may be required • Rooms where the work is being done may not be usable for a while as furniture, kitchen units and other items may need to be temporarily removed • Fittings such as skirting boards, window sills and plug sockets that are on the wall that is being insulated will need to be removed and reattached afterwards • Pipework and wiring may need to be relaid • Works are likely to be undertaken throughout the property at the same time and will generate dust and noise • Contractors will require water and power, and possibly the use of a toilet • The newly insulated walls and adjacent surfaces will need to be re-decorated when the work has finished

Windows

Ideally, the insulation board is fitted to the inside of the window and door recesses to prevent cold patches developing where condensation can gather. But, as is the case in this model, this is sometimes not possible.

Surface coating

This is the new plasterwork that covers the insulation boards. It can be painted (green in this case) or papered just like a normal internal wall.

Approved systems and installers External wall insulation is a relatively new technique and should only be undertaken by competent installers using a recognised system. We have identified six tried-and-tested external wall insulation systems developed by the following companies: Weber (www.netweber.co.uk) Rockwool (www.rockwool.co.uk) Knauf Marmorit (www.marmorit.co.uk) Parex (www.parex.co.uk) Wetherby (www.wbs-ltd.co.uk) Structherm (www.structherm.co.uk)

All of these are large and well-established manufacturers. Between them they offer a range of external wall insulation systems suitable for different homes and different specifications. You can read more about their systems on the following pages. The firms that actually install the insulation are local contractors who have been vetted by the manufacturers and are ‘approved installers’. A list of these accompanies the description of each system. Some are approved installers for two or more systems. How you select a contractor is up to you. Some householders will research the different systems to find one that they like, and then find an approved contractor. Others find a local contractor they trust and accept the system that they are approved for. Our expectation is that your wall insulation project will go smoothly. But if you have an enquiry or complaint about the contractor or their work, please contact their customer services team directly.


Many of the contractors listed on the following pages may offer internal wall insulation as well. For other installers of internal wall insulation you can contact the following organisations: Federation of Master Builders Gordon Fisher House, 14/15 Great James Street London WC1N 3DP 020 7242 7583 www.fmb.org.uk National Insulation Association 2 Vimy Court, Vimy Road Leighton Buzzard, Beds LU7 1FG 08451 636363 www.nationalinsulationassociation.org.uk

Building regulations and planning permission When undertaking any construction work, you will need to take into account that you may have to apply for planning permission or comply with building regulations. If your property is listed, or in a conservation area or Area of Outstanding Natural Beauty (AONB), this process may be more complex. Planning consent can take 8 to 12 weeks and even longer if other conditions (such as a request for a sample of the finish) are imposed. An hourly rate may be charged to obtain pre-planning advice so sometimes it can be easier and more efficient to submit for planning permission without this. This is really dependent on your circumstances and level of knowledge alongside any other advice you may have received.

map may also be required. It’s worth using their experience to vet drawings, structural and thermal calculations, and schedules of works to highlight any possible snags they may note, especially as they may inspect during the construction works. Fees will be charged for both the planning and building regulations and the associated maps or pre-planning enquiry etc, and they can be significant. Each individual local authority’s website is a valuable resource for seeking further information on this subject.

Building control response times are dependent on the local authority area, but likely to take 4 to 6 weeks. These can be submitted using ‘full plans’ or a ‘building notice’, and a planning


Additional energy efficiency options If you’re still looking for other ways to improve the energy efficiency of your home, why not consider the following:

Energy efficient appliances It’s surprising how much electricity certain appliances use. Check our handy guide to seeing ‘what uses watt’ (see www.cse.org.uk/how-much-electricity). You could also consider getting a wireless energy monitor to track what you’re using at any given time (in many places you can loan these from your local library for a few weeks) and look for Arated appliances when the time comes to replace them.

Loft insulation

Draught proofing This is a really simple and cost effective way to improve the comfort of your home. Pay particular attention to windows and doors. Look for window seals, door brushes (below) and letter box brushes.


When was the last time you looked in your loft? If it was a few years ago, then the chances are you’ll have very little or no loft insulation. The recommended amount of loft insulation is now 270mm (which is about 11 inches). Considering that you lose approximately 25% of your heat through the roof, loft insulation really is one of the most effective and economical ways to keep your home warm.

Renewable technologies This takes energy saving to the next level! There are several technologies well suited to individual households. Biomass

Heat pumps

The most common biomass fuels are logs, woodchip and pellets (below). Stoves are generally used as room heaters alongside a central heating system run on gas or oil, but they can be fitted with back boilers to supply or top up hot water. Modern stoves and boilers are typically 80-90% efficient because they are more controlled than open fires (where as much as 85% of heat is lost up the chimney). Biomass systems get close to being carbon neutral as the CO2 released during burning is balanced by the amount absorbed during growth of the plant or tree.

If you have a well-insulated home you could consider a heat pump. These work like fridges in reverse, drawing latent heat from the air, the ground or a body of water. A range of factors influence how much money and CO2 a heat pump will save. This includes whether you use renewable energy for powering the pump.

Solar hot water Ideal for those with south-facing, un-shaded roof space. Different to solar PV, these panels are linked to your hot water system. Depending on your hot water requirements the panels may generate more than enough hot water for you in the summer months. You may be able to claim the Renewable Heat Incentive if you have a solar hot water system. For further information on the Renewable Heat Incentive see www.cse.org.uk/rhi

Solar PV Ideal if you have a south-facing, unshaded roof space. These panels use the sun’s energy to generate electricity. By having solar PV panels you’ll reduce your electricity bill and be paid for the electricity you produce via the feed-in tariff, regardless of whether you use it yourself or export it to the grid.
