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.
In this guide...
"Free stuff" – we're talking £1,000s worth – is a sexier phrase than "Energy Company Obligations (ECO) scheme", but they're the same thing. Generally, freebies are only for people who get tax credits and have an income of £16,010 or less, or those who are receiving certain benefits such as pension credit. Many big energy providers are giving away:
Boilers: typically costing up to £2,300, you could get one free if you satisfy providers criteria – full info.
Loft and cavity wall insulation: worth around £700. Unusually, British Gas offers it to all, regardless of income or whether you are its customer – full info.
There's also the Green Deal Home Improvement Fund. It offers up to £1,850 cashback towards energy saving measures such as floor insulation, double or secondary glazing, fan-assisted storage heaters and more.
The Green Deal scheme is ending and the Home Improvement Fund is only open until 30 Sep or until the remaining £4m funding runs out – whichever happens sooner. See the Green Deal Mythbusting guide for full details.
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?
Some offers below, such as the British Gas free insulation offer, aren't available if you live in Northern Ireland. But you may be able to get free insulation and other freebies through other schemes. Give the Energy Saving Trust's helpline a call on 0800 1422 865 to see what's available to you.
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.

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, if it needs moving or you need extra radiators. You should be told about this beforehand.
You're likely to qualify if:
You get tax credits and have a household income of less than £16,010 or...
- You receive income-based benefits, such as pension credit or income support, and you have 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 are complex, so a quick way to check if you qualify is to call the Energy Saving Trust advice service and answer a few basic questions on 0300 123 1234 (England and Wales), 0800 1422 865 (Northern Ireland) or 0808 808 22 82 (Scotland). Also see providers' criteria in How to get it.
How do I 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.
What's offered by each provider?
See the eligibility criteria online or call 0800 316 3392. British Gas says that some contribution will be required for all boiler installations. It'll let you know before any work takes place.
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.
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.
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 £340/year.
It's likely new boilers are top of many homebuyers' wishlists, so this could boost your house price, too.
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 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.
Cavity wall and loft insulation is worth around £700 and can slice about £300 off energy bills each year, and energy firms are offering them free to certain groups.
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.
Providers usually require you to get child tax credit and have an income of £16,010 or under, or to be receiving certain benefits such as pension credit. See providers' eligibility criteria below.
You won't be able to get free cavity wall and loft 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).

Who can get it?
Anyone, regardless of whether you're a British Gas customer, providing you have a suitable home. 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. See full eligibility details below.
If you qualify (British Gas says nine out of 10 homes will) it'll arrange for a survey to be booked.
British Gas decides if your home is eligible 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.
Your home will not qualify if...
- You have solid walls – you cannot get these insulated, it's only for cavity walls.
- You have 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.
- You live in Northern Ireland.
- You live in the following postcode areas: PH21-PH27, PH32-PH40, PA20-27, PA30-PA38, AB and IV and the Scottish Islands.
- Having loft and cavity insulation fitted won't save a certain amount of carbon.
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 qualify for free insulation won't need extras.
How long will it take?
If your home is eligible for insulation, British Gas will arrange for a survey to take place. On average it takes four weeks to book a survey and a further four weeks for insulation to be fitted (though it can be more).
If your home doesn't meet the British Gas requirements, these providers give free insulation but only to those who meet the benefits criteria. All offers are ongoing, with no limit on the number of free installations.
How much can you save?
The Energy Saving Trust reckons cavity insulation typically costs £400 to £500 to install (including building work), and can save an average three-bedroom home up to £160/year on its bills. Loft insulation costs about £300 and can save £150/year.
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.
You usually won't qualify if...
You live in a flat and can't coordinate 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.
I don't qualify for free insulation, how can I get it cheaply?
If you don't qualify for the schemes above, 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
Despite recent cuts to gas prices from all the big six, energy prices are up overall. Locking in with a cheap fix is one way to avoid future price hikes, and cut costs now – especially if you're on a standard tariff.
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.
It's the same gas, the same electricity, the same safety. All that changes are the customer service and the price you pay. For more on this, plus top fixes, see our Cheap Gas & Electricity guide.
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.
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 having the heating on only 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 the most benefit.
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 Cheap Heating Oil.
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 underbilling, you'll have a big whack to pay when they get an actual reading. If they're overbilling, 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, switch to a billed meter. You may have to pay for one, but the savings are usually worth it.
Often, firms won't let you switch meters because of 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 & Electricity guide.
