Question 1

How much does loft insulation cost?

Accepted Answer

The cost depends on your home size and existing insulation. Installing 270mm of mineral wool from scratch typically costs around £900 in Great Britain. Topping up from 120mm to 270mm costs around £750. We offer free surveys and no-obligation quotes so you'll know the exact cost before any work begins. With 0% VAT until March 2027, now is an ideal time to insulate.

Question 2

How long does insulation installation take?

Accepted Answer

Most loft insulation jobs are completed within a single day. Cavity wall insulation typically takes just 2–3 hours. Warm roof insulation and floor insulation may take 1–2 days depending on the property size. We'll always give you a clear timeframe during your free survey.

Question 3

Do I need planning permission for insulation?

Accepted Answer

In most cases, no. Loft insulation, cavity wall insulation, floor insulation and ProPERLA Masonry Creme do not require planning permission. However, if your property is listed or in a conservation area, you should check with your local authority first. Building Regulations approval may be required for certain types of work — we handle all compliance for you.

Question 4

What is the recommended depth for loft insulation?

Accepted Answer

Building Regulations recommend a minimum depth of 270mm for mineral wool insulation. Many older homes have only 100–120mm. Topping up to 270mm is one of the most cost-effective energy improvements you can make. If you're unsure how much insulation you have, we'll measure it during your free survey.

Question 5

How much can I save on energy bills with insulation?

Accepted Answer

Savings vary by property type and existing insulation. Typical annual savings with full loft insulation are £230–£380. Cavity wall insulation can save an additional £100–£250 per year. ProPERLA Masonry Creme helps by keeping walls dry — damp walls lose heat twice as fast as dry ones.

Question 6

Is there 0% VAT on insulation?

Accepted Answer

Yes! The UK government has reduced VAT on energy-saving materials to 0% until March 2027. This applies to loft insulation, wall insulation, floor insulation and other qualifying materials. This means you pay no VAT on our insulation services — a significant saving.

Question 7

What is ProPERLA Masonry Creme and how does it work?

Accepted Answer

ProPERLA Masonry Creme is a clear, breathable waterproof coating for exterior brick, stone and concrete walls. It penetrates up to 17mm into the masonry, chemically bonding to create a super hydrophobic (water-repelling) surface. It reduces water absorption by 96.3%, preventing damp, salt efflorescence and frost damage. It dries clear, doesn't alter the building's appearance, and comes with a 20-year manufacturer's guarantee.

Question 8

How do I know if my cavity walls are insulated?

Accepted Answer

If your home was built after the 1920s, it likely has cavity walls. You can check by looking at the external brickwork — if the bricks are all laid lengthwise in a uniform pattern, you probably have cavity walls. To check if they're already insulated, a professional can use a borescope to inspect the cavity through a small drilled hole, or check for evidence of previous drill holes in the mortar. We check this during our free survey.

Question 9

Can I insulate my loft myself?

Accepted Answer

Simple loft insulation (laying rolls between joists) can be a DIY job if your loft is easily accessible, free of damp, and the joists are regular. However, for warm roof insulation, flat roofs, damp lofts, or if you need to insulate pipes and tanks, professional installation is recommended. We ensure proper ventilation, compliance with Building Regulations, and a guaranteed finish.

Question 10

What happens during the free survey?

Accepted Answer

A qualified surveyor visits your property to assess the current insulation levels, measure the area, check for any damp or ventilation issues, and discuss the best options for your home. You'll receive a detailed quote with no obligation. The survey typically takes 30–45 minutes. All insulation surveys are completely free with no deposit required.

Question 11

How does waste removal pricing work?

Accepted Answer

Waste removal is priced by load size and waste type. You can use our online booking calculator for an instant quote. Prices start from £60 for single bulky items up to £500 for full loads of mixed heavy waste. A 20% deposit secures your collection slot, with the remainder due on the day. No hidden fees — the price you see is the price you pay.

Question 12

Are you fully insured and licensed?

Accepted Answer

Yes. We carry full public liability insurance for all insulation and property maintenance work. We are a licensed waste carrier registered with the Environment Agency. All our insulation materials are BBA approved and meet Building Regulations. We offer a 25-year guarantee on all insulation work.
