Miro gave me a fair price and had a slot so could do the work next day. He did an excellent job and was polite, clean and tidy. Had a short lunch break and was finished mid afternoon. Would recommend.

External wall insulation installers – Rated People
What can an external wall insulation specialist help with?
External wall insulation is a multi-layered construction process that wraps the outside of your property in a thermal blanket. Qualified EWI contractors possess the specialist scaffolding, materials, and rendering skills required to transform your home’s efficiency:
- Solid wall insulation fitting: Securing high-performance insulation boards directly to older brick or stone exterior walls using specialised mechanical fixers and adhesive mortars.
- Weatherproof rendering and cladding: Applying a durable reinforcement mesh layer followed by a decorative top-coat render. You can choose from smooth, textured, tiled, painted, or panelled finishes to boost curb appeal.
- Moisture control and vapour barriers: Installing breathable membranes and vapour barriers that stop exterior rainwater from penetrating while warming the walls to reduce internal condensation.
- Full site preparation and re-fixing: Managing the entire layout from erecting safe scaffolding to removing and cleanly re-fixing downpipes, satellite dishes, and fixtures once the insulation is complete.
How much does external wall insulation cost and save?
While solid wall insulation requires a larger upfront investment than basic cavity filling, the subsequent heating bill savings are significantly higher. Home improvements of this scale are priced based on the footprint of the building and wall condition:
- Average installation costs: Total project costs typically range between £8,000 and £22,000. A standard semi-detached house usually falls in the middle of this scale, while large detached properties sit at the top.
- Energy bill savings: According to the Energy Saving Trust, wrapping uninsulated solid walls can save you hundreds of pounds annually on your energy bills, making it a highly rewarding long-term investment.
- Government funding & grants: You may be eligible for a financial grant to cover or heavily subsidise these costs under schemes like the Energy Company Obligation (ECO). Check with your energy supplier or the Energy Saving Trust for details.

Internal vs. external: Is EWI right for your property type?
Before booking a specialist, it is essential to check your underlying wall structure and weigh up your installation choices:
- Are my walls solid or cavity? EWI is designed for older solid walls (typically built before the 1920s). You can identify solid walls by an alternating brick pattern of full and half-length bricks, or by measuring your door opening—solid walls are usually less than 30cm thick.
- Minimal internal disruption: Unlike internal insulation, which requires losing valuable room space, moving radiators, and complete interior redecoration, EWI is fitted entirely outside. You can live inside undisturbed while the work takes place.
- Timeline and weather: On average, an installation takes 3 to 6 weeks to complete. Because the rendering process requires dry conditions, bad winter weather can extend this timeframe.
- Planning permission regulations: If your chosen render finish dramatically changes the look of your house compared to your neighbours, you may need planning permission. This is mandatory if you live in a listed building or a designated conservation area.

Other external wall insulation FAQ's
What qualifications and insurance should I check for?
While there are no strict legal frameworks, look for tree surgeons or installers holding a City & Guilds NVQ Certificate or Diploma in Insulation and Building Treatments. Reputable companies should also hold Public Liability Insurance and ideally be members of trade bodies like the Insulated Render and Cladding Association (INCA).
What are the top questions to ask an EWI contractor before hiring?
Protect your project by asking: Do you provide a comprehensive insurance-backed guarantee for the render? Will full scaffolding costs be handled within your fixed quote? Will you install an integrated vapour barrier to prevent moisture locks inside the wall structure?
Will external wall insulation fix damp problems inside my house?
Yes, if it is caused by condensation. By warming the temperature of your internal walls, EWI prevents warm, humid indoor air from condensing into water droplets on cold surfaces. Note that it cannot cure rising damp caused by a failed ground-floor damp proof course (DPC).

He quoted £100,000 to do the job in 6 weeks & promised it would be stress free, At 12 weeks in He was told I no longer wanted him to complete the job as I received an electric shock from a socket that was left as a bare cable protruding from the wall. He blamed everybody else then fired the only two decent builders as he held them responsible. Even though I had paid the third stage payment a day previous, I was too distressed and my health was declining due to the anxiety and stress he had caused. Avoid!!

STAY well away from this company. Quoted to fit stair carpet and stair rods. Arrived late and Ryan started to cut the stair rods. Ryan stayed for 3 hours then just walked out with no warning and never came back. I then found out that he cut 8 of the stair rods incorrectly. I advised him of this and he said he would replace. After not responding to my texts I can assume he is not replacing them which has now left me £88.00 out of pocket to replace. Be warned .
Serious and hard working. Since 1998 in EU and from 2010 in UK . "Work smart not hard" .
Absolutely brilliant. He was very professional did a fantastic job. I would 100% recommend
