There are a lot of freebies on offer from energy providers if your home qualifies, from new boilers to loft and cavity wall insulation.
This guide shows how to grab these crocks of gold, including current offers, who can get them and how to apply.

Why can you get free stuff?
Free stuff – we're talking £1,000s' worth. It’s a sexier phrase than "Energy Company Obligations (Eco) scheme", but they’re the same thing. Most of the big energy providers are giving free boilers, plus loft and cavity wall insulation, to some people who get tax credits and have an income of £15,860 or less, or are receiving certain benefits such as pension credit.
But British Gas is giving away free loft and cavity wall insulation to anyone with a suitable home - you don't need to meet the benefit criteria.
Boosting your home's efficiency can save you hundreds of pounds a year on your gas and electricity bills and, just as importantly, make your home a more pleasant place to live.
These deals are closely linked to the Government's Green Deal initiative. If you don't qualify for the freebies below, it's designed to let you pay for energy-efficient home improvements such as insulation, underfloor heating and double glazing from the 'savings' you make on energy bills. It's complex, so see our Green Deal Mythbuster to decide if it could help you.
Why do energy providers do this?
Big providers have obligations to pump money into making homes more efficient, especially for tough-to-reach groups. If they miss targets, they get big fines.
It doesn't matter which company you're signed up to either. This isn't just about suppliers helping their own customers - these big beasts just need to put money into the system.
What options are there in Northern Ireland?
The offers below aren't available if you live in Northern Ireland. But you may be able to get free insulation through other schemes. Give the Energy Saving Trust's helpline a call on 0300 123 1234 to see what's available to you.
I rent my property, can I get the freebies?
It depends on which scheme you're applying to, so do check. But normally you'll be allowed, with the landlord's permission.
I live in a flat, am I still eligible?
You should be able to install free home improvements in flats, but you may have to get it installed for the whole block, which means getting agreement from all your neighbours.

Energy providers' freebies used to focus on free loft and cavity wall insulation. Boilers are also up for grabs from some providers.
What can you get?
A new boiler typically costs £2,300, according to the Energy Saving Trust, so this is a fabulous freebie. If your boiler isn't inefficient, just broken, you may be offered a repair, rather than a new boiler.
The offer includes fitting, though there may be an extra cost if an engineer needs to carry out extra work, for example, it needs moving or you need extra radiators. You should be told about this beforehand.
Who can get it?
You're likely to qualify if:
- You get tax credits and have a household income of less than £15,860, OR
- You receive income-based benefits, such as pension credit or income support, and you’ve either children, a disabled person in the household, or are over 60.
You won't be able to get a free boiler if you live in a housing association property or are a council tenant. Instead, this will be arranged through their own schemes.
The criteria's complex, so a quick way to check if you qualify is to call the Energy Saving Advice Service and answer a few basic questions on 0300 123 1234 (England), 0800 512 012 (Wales) or 0808 808 22 82 (Scotland). Also see providers' criteria in How to get it.
What kind of boiler do you need to have?
You need to have a broken or inefficient boiler. If you've a new-ish, working A or B rated boiler, you probably won't qualify.
This is decided on a case-by-case basis through a free inspection. It's based on a number of factors, including the boiler's efficiency, age and condition.
The energy companies will usually just replace gas boilers, not oil. If you don't have a boiler already, you can't get a new system installed.
How much can you save?
The Energy Saving Trust says boilers account for about 55% of what people spend each year on energy bills, so an efficient boiler makes a big difference. Depending on your boiler's age, a shiny new efficient one could save you up to £300/year.
It's likely new boilers are top of many homebuyers' wishlists, so this could boost your house price too.
How long will it take?
The energy companies say it typically takes four to 12 weeks from when you first apply to get the boiler installed. Fitting the boiler usually takes from a few days to a week, though it varies depending on property.
How to get a free boiler
Just call a provider for a free assessment. You're free to pick any energy company offering the deal - you don't need to be a customer.
All deals are ongoing, with no limit on the number of free installations. If you apply, we'd love to hear your Free boiler experiences. Here's a rundown:
- EDF Energy. Fill out an application form online or call 0800 096 8634. See its eligibility criteria. If the boiler installation requires extra work, such as additional radiators, in some cases EDF may ask for a contribution to the costs. It will let you know beforehand.
- E.on. Apply via E.on's site or call 0330 400 1195. See its eligibility criteria. E.on says there may be an extra charge if it needs to carry out extra work, for example, putting in additional radiators or moving a boiler to another location. It will let you know beforehand.
- Npower. Apply on Npower's site or call 0800 980 3355. Also see its eligibility checker.
- Scottish & Southern (SSE). Fill out an online enquiry form. See its eligibility criteria. SSE says installations are subject to a survey. If replacing your boiler won't save enough energy to help it meet its targets or there are technical problems, it may ask you to pay something towards the cost. If this happens, it's worth trying another provider instead.
Free loft and cavity wall insulation
Cavity wall and loft insulation can slice about £300 off energy bills each year, and energy firms are offering them free to certain groups.
What can you get?
Some of the big six providers are giving away free loft and cavity wall insulation.
- Cavity wall insulation. Most homes built since 1920 have a gap between internal and external walls. Filling the cavity with insulating mineral wool and foam means cold air's kept out, and warm air stays in.
- Loft insulation. Up to a quarter of your home's heat escapes through the roof, but you can solve this by laying mineral wool under the rafters.
Who can get this?
British Gas is currently the only energy provider with no restrictions on your income or the number of benefits you're receiving for free insulation.
The others require you to get child tax credit and have an income of £15,860 or under, or to be receiving certain benefits such as pension credit. See providers' eligibility criteria below.
You won't be able to get a free insulation if you live in a housing association property or are a council tenant. The idea is they will arrange to do this for you though their own schemes.
A quick way to check if you qualify is to call the Energy Saving Trust and answer a few basic questions on 0300 123 1234 (England), 0800 512 012 (Wales) or 0808 808 22 82 (Scotland).
Is your property suitable?
Not all properties are suitable for cavity wall or loft insulation. Most providers conduct a free survey.
You usually won't qualify if...
- You live in a flat and can't co-ordinate with all other tenants.
- Your home is timber or metal-framed, or made from natural stone or concrete.
- If you've damp problems. The Energy Saving Trust says you should sort these out first.
You may need to pay extra for scaffolding to get the insulation fitted. These costs aren't included in some offers.
How much can you save?
The Energy Saving Trust reckons cavity insulation typically costs £400 to install (including building work), and can save an average three-bedroom home up to £140/year on its bills. Loft insulation costs about £300 and can save £150 per year.
How to get free insulation
Just call a provider for a free assessment. You're free to pick any provider - you don't need to be a customer.
If you qualify for it, our top pick is British Gas. It's the only provider giving insulation away free to those with a qualifying home, and it's also offering £50 on a shopping gift card. If British Gas isn't suitable, see our full rundown of other providers below.
Free loft & cavity wall insulation, plus £50 high street gift card (use at Argos & J Lewis) Gift card ends Sat 30 Aug. All-in could be worth £700. Non-BG customers qualify
If your home isn’t properly insulated, British Gas (even if you're not one of its customers) is once again installing free loft and cavity wall insulation in suitable homes (not N Ireland). All-in this can be worth £700, according to the Energy Saving Trust. Until recently, only those on certain benefits could get this.
- Ends Sat 30 Aug. Get a free £50 high street gift card. If you qualify for the free insulation, and apply either by filling out the callback form below, or by calling 0800 294 9126 (or 0330 100 3640 for the mobile friendly version), we've blagged a £50 Compliments Card valid at John Lewis, Argos, Toys-R-Us and more.
To qualify for the voucher, you'll need brand new insulation, not just a top-up of existing insulation.
Which homes qualify?
The offer’s available to those with a suitable home until Sat 30 Aug, but only in England, Scotland and Wales, not Northern Ireland. Council and housing association homes have their own schemes, so aren’t included. If you live in a flat the whole block will need to get it.
You'll be told if you're eligible after a survey, but see our full list of which homes qualify:
If you’ve solid walls, you cannot get these insulated – it’s only for cavity walls.
If you've existing loft insulation, it'll need to be less than 50mm thick and cover less than a third of the loft to qualify for this deal.
Unfortunately the following postcodes aren't eligible for this deal: PH21-PH27, PH32-PH40, PA20-27, PA30-PA38, AB and IV and the Scottish Islands.
British Gas can only insulate homes where a certain amount of carbon will be saved. It decides this on a case-by-case basis, but says 90% of homes qualify. If you don’t meet its criteria and need to pay cash for the insulation, it will tell you before you go ahead.
Are there any extra costs?
Some extra costs (such as damp removal or putting up scaffolding) won’t be covered. You’ll be told about these before insulation is arranged.
British Gas has told us that 90% of those who apply, will qualify as they won't need extras.
How long will it take?
If your home is eligible for the deal, British Gas will arrange for a free survey to take place. Then, subject to the survey's findings, it'll fit installation two weeks after.
What is Eco and how does it work?
Big providers have obligations to pump money into making homes more efficient, through Eco. If they miss these targets, they get big fines and that's why British Gas has changed its criteria for insulation.
What is a Compliments Card?
Sign up to this deal, and you get a £50 Compliments Card. It's redeemable at John Lewis, Argos, House of Fraser, Selfridges, Topshop, Waterstones, Debenhams, New Look, WHSmith, Halfords and more (see full list). You'll need full insulation (cavity and/or loft) to qualify for the card, ie, not just a top up on existing insulation.
It will arrive by post 60 days after installation.
Why will British Gas call me?
British Gas needs to call you to check your home is eligible. It will call up to 10 times (no more than three times in a day) and will then email.

If your home doesn't meet the British Gas requirements, these providers also give free insulation but only to those who meet the benefit criteria. All offers are ongoing, with no limit on the number of free installations.
- EDF. Fill out an application form online or call 0800 096 8634. See its eligibility criteria.
- E.on. Apply via E.on's site or call 0330 4001195. See its eligibility criteria.
- Npower. Apply on Npower's site or call 0800 072 1740. Also see its eligibility checker.
- Scottish & Southern. Call 0800 975 2844 or fill out an online enquiry form. See its eligibility criteria.
Will my house be suitable for cavity wall insulation?
Not all houses will be suitable for cavity wall insulation. According to the Energy Saving Trust, your home will usually be suitable for cavity wall insulation if:
- Its external walls are unfilled cavity walls.
- The cavity is at least 50mm wide.
- The masonry or brickwork of your property is in good condition.
- It's more than 10 years old (most newer houses will have insulation already).
- The walls are not exposed to driving rain.
Is there any help if I've got solid walls?
Anyone who needs solid wall or 'hard to treat' cavity wall insulation may be entitled to free cash from energy providers to help. You can either pay the remaining cost off yourself or take out a Green Deal loan to pay for it.
What are solid walls?
About 7 million homes in Britain were built with solid rather than cavity walls – 31% of the total housing stock.
Solid walls are much harder to insulate than cavity walls. With a cavity wall, you can often easily fill in the cavity with foam and mineral wool for less than £500. However, to insulate a solid wall, you need to add material either to the outside or the inside of a wall.
How to get help
It's still early days for the scheme, so many providers are still setting things up. If you pay a Green Deal assessor about £120 to visit your home, they will work out where, in an energy sense, it's leaking cash and should let you know if you're eligible for extra help from energy providers. For a full explanation, see the Green Deal guide.
Don't shell out for an assessment before doing an online check first. The easy 'n' speedy way to see what improvements could help is answering a few questions on 1 Green Place's home survey tool (this is from an assessor organisation, so be aware it may contact you).
I don't qualify for free insulation, how can I get it cheaply?
If you don't qualify for the schemes above, first check out the Government's Green Deal initiative. It's designed to let you pay for energy-efficient home improvements such as insulation, underfloor heating and double glazing from the 'savings' you make on energy bills. It's complex, so see our Green Deal Mythbuster to decide.
If you don't want to get the Green Deal, look for an installer on the National Insulation Association site. As a benchmark, The Energy Saving Trust reckons cavity insulation typically costs £450 to £500 to install, and loft insulation about £300.
The DIY route could work out cheaper for loft insulation at about £150. For more help, Homebuilding magazine has a handy step-by-step guide to insulating your loft.

Other ways to cut your energy bill
Also ensure you're on the cheapest energy tariff and do the energy-saving basics:
Consider fixing to beat price hikes
All the big six energy providers upped prices last winter. Locking in with a cheap fix is one way to avoid future price hikes. For more on this, plus top fixes, see Cheap Gas & Elec.
Our Cheap Energy Club checks you're on the cheapest deal and handles the switch for you. Plus to encourage you, there's up to £30 extra if you switch via Cheap Energy Club.
Thrifty heat-saving tips
If you wander round the house in boxers or bra 'n' knickers with radiators on full and windows wide open... STOP IT.
Sensible changes can save you large, from draught excluders to notching down the thermostat. Here are a few thrifty ways to keep your home toasty.
For more tips, join the Old Style forum board's Prepare for winter thread. Also see the Great Energy-Saving Hunt and our Energy Mythbusting guide. If you use heating oil to heat your home, you can save too. Follow the simple steps in our Cheap Heating Oil guide.
Make your own sausage dog draft excluder
Draught excluders stop heat escaping in gaps between the door and the floor. For a cheap version, roll up a towel and use that instead.
If you're a creative type, you can always make your own sausage dog draft excluder from an old pair of woolly tights filled with some stuffing or old socks (use buttons for eyes).
Line curtains with cheap fleece
Chunky window-wear, especially lined and insulated, will keep the warmth in. If you're on a budget, line curtains yourself with cheap fleece blankets (from about £2 at places like Ikea and Asda). See how to line your own curtains with fleece.
Remember, the sun can also help heat your house. During the daytime, keep curtains open and let it do the work for you.
Keep doors closed
It's better to keep doors closed for the area you want heated. Radiators, electric panel heaters and convection heaters all work by creating a convection current in a room. As hot air rises, it circles around to the other side of the room, cools and sinks and travels back along the floor to the heater to be reheated again.
Keep windows closed too. According to not-for-profit energy company Ebico, 25% of heat is lost through open doors and windows.
Put shelves above radiators
Even if you're not handy with DIY and your shelving slopes like a ski resort, a well-placed ledge can help. Putting a shelf above a radiator helps prevent the heat rising, especially if you have high ceilings, keeping the warmth closer to the ground.
However, don’t put any shelving directly on top of a radiator, which will trap the heat rather than channelling it around the room.
Don't leave the heating on low all day
You'll save energy, and therefore money, by only having the heating on when it's required. Using a timer is best, because your thermostat is designed to turn your heating system on and off to keep your home at the temperature you set it.
If you’re really worried about getting chilly, switch the timer on a little bit earlier, so the house will be nice and toasty when needed, but you’re not pumping out energy all day.
Put reflective panels behind radiators
Most heat, 35% in fact, is lost through external walls. Radiator reflector panels bounce heat back into the room rather than let it pass through external walls. The Energy Saving Trust says homes with uninsulated walls will get most benefit.
Don't assume dual fuel is always cheapest
Logically, dual fuel (gas and electricity from the same supplier) should be cheaper and it often is, yet not always.
During your comparison, also check the cost of the cheapest dual fuel supplier against separate cheap gas and cheap electricity suppliers.
Switch to monthly direct debit
Fixed monthly direct debit payments, where you pay a fixed estimate each month, save you 5-10%, as companies are sure you won't default and they earn interest on any overpayments. These should be refunded at the end of the year.
Do a meter reading every time
Every time you receive a bill, do a meter reading. Don't rely on your energy provider's estimate, these are often way out. If they're under-billing, you'll have a big whack to pay at the end of the year. If they're over-billing, then they've unfairly got your cash.
If your direct debit is way off-kilter, call up and request it's changed. You have a range of rights to ensure it's correct. See the full Energy Direct Debits guide for template letters.
Switch to your company's internet tariff
It'll usually save you up to 10% over the standard tariff, and all it really means is you get your bills emailed.
Avoid prepayment meters if you can
While a push from the Government means it's getting better, those on prepayment meters are still pretty hard done by compared with those who pay by direct debit. If possible, try to switch to a billed meter. You may have to pay to get one, but the savings are usually worth it.
Often, firms won't let you, due to credit score or income difficulties. For full info on how to ditch a prepayment meter for a credit meter - or if you can't, how to save on a prepay meter - see the full Cheap Prepaid Gas & Elec guide.
