Loft Insulation


An uninsulated loft space (the area at the top of a house, directly under the roof) will let around a quarter of a home’s heat escape.

Loft insulation involves, quite simply, lining the floor of your loft with a highly thermally-efficient insulation material. The insulation can either be rolled out in a layer or blown as loose material onto the floor space. The recommended depth of insulation is 270mm.

It is one of the easiest methods of improving home energy efficiency. Installed in just a couple of hours, it can reduce your heating bills by around £145 per year. With these type of savings possible, the cost of installation will pay for itself time and time again. It also reduces the amount of C02 emitted into the atmosphere.

With energy becoming more and more expensive, there has never been a better time to install insulation and start benefiting from reduced heating bills.

Domestic and General are expert installers of various types of loft insulation and can offer advice on exactly which loft insulation material would best suit your property.

Loft Insulation Process

Loft insulation is one of the easiest methods of improving home energy efficiency. Domestic and General install it in just a couple of hours making it a quick and convenient way for you to reduce your heating bills.

Our handy guide below explains what you can expect.

  1. One of our friendly surveyors will visit your property, at your convenience, to advise on what type and depth of insulation your loft requires
  2. Our surveyor will provide you with a quote for installing the insulation and discuss with you any non-repayable grants you may be eligible for
  3. We’ll arrange a time with you for one of our fully trained installation crews to come and install the insulation, again at your convenience. Remember, it only takes an hour or two so won’t be too much of a disruption for you
  4. On arrival in our specially equipped van, we will show you our Domestic and General identification and lay dust sheets to ensure your home remains clean and tidy
  5. Our installation technicians will check where the joists are before putting any weight on them and use boards to walk or crawl on where necessary. We will also thoroughly check the loft space for cables, lights or ventilation issues that must be accommodated during the installation
  6. Insulation is laid or blown (depending on the insulation type recommended for your loft) between the joists
  7. Vent wedges are fitted to ensure air flow in the loft space

8.If required, pipes and cold water tanks are fitted with insulation and the loft hatch is draught proofed. We can also install new loft hatches and loft ladders making access to your loft space easier and safer 

9.You may want boarding laid over all or part of the insulation so the loft becomes a useable space for storage

10.The crew cleans up and you are informed the job is complete

11.You enjoy increased energy efficiency for your home and watch your heating bill fall

What else can I do to insulate my home?

Deciding to insulate your loft space is a great first step to achieving better energy efficiency for your home and the associated reductions in your heating bills. However, to really capitalise on reductions in heating bills through energy efficiency, you should also consider insulating your walls too.

Walls, depending on whether they are solid or cavity-constructed, allow up to around 45 per cent of a home’s heat escape.

Cavity-constructed homes

If you have a home built after the 1930s the chances are that you home is constructed from cavity walls and so the cavity can be filled with insulation to prevent such high levels of heat loss.

Solid brick homes

External wall insulation is a highly advanced insulating system that is applied to a house’s outside walls. It comprises of a layer of insulation, a layer of insulating render, followed by a final coat of render finished to the desired decorative effect, making it particularly suitable for solid wall properties that need some cosmetic attention.

If you have a period property built before the 1930s it’s very likely that it is constructed from solid brick walls, in other words there is not a cavity space that can be filled with insulation. The methods used for insulating solid wall properties are known as external wall insulation or internal wall insulation.

Not surprisingly, internal wall insulation is a system of insulation applied to a house’s inside walls. Internal wall insulation is an excellent choice when renovating the rooms of a solid wall property as internal wall insulation is finished with a professional layer of plasterwork creating perfect wall surfaces for you to decorate as desired.
