Anglian Home Improvements is the UK’s largest double glazing installer by volume, manufacturing all products at its Norwich factory and covering England, Scotland, and Wales. Founded in 1966, the company installs over 500,000 home improvement products annually and offers uPVC, aluminium, and timber windows alongside doors, conservatories, and roofline products.
We rate Anglian 7 out of 10. Product quality and accreditations are strong, the 10-year insurance-backed guarantee provides genuine protection, and the scrappage scheme offers real savings – but the 11.9% APR finance, aggressive sales tactics, and mixed after-sales service stop it reaching higher.
What most comparison sites won’t tell you: Anglian’s parent company ASHI Group now owns Everest and Safestyle too, meaning three of the UK’s biggest window brands are controlled by the same private equity firm. If you’re getting quotes from all three to compare, you’re effectively comparing the same owner. This review explains what that means for your quote and whether Anglian deserves your business in 2026.

Anglian Windows Pricing
Anglian doesn’t publish prices – uPVC windows start from around £250-£570 per unit for a standard 60x90cm window, with a typical 3-bed house costing £4,500-£6,000 fully installed.
Anglian operates a bespoke quote model with no published price list. Every quote requires a home survey or remote consultation, and prices vary significantly by window style, material, size, and location. The ranges below come from verified third-party sources – Anglian itself does not confirm or deny these figures.
| Material | Per Window (60×90cm) | 3-Bed House Estimate | Energy Rating |
|---|---|---|---|
| uPVC | £250–£570 | £4,500–£6,000 | A to A++ |
| Aluminium | £500–£605 | £6,000–£8,000 | A rated |
| Composite | £575–£625 | £7,000–£9,000 | A rated |
| Timber | £845–£910 | £10,000–£14,000 | A rated |
Prices are third-party estimates for a standard window (approx. 60×90cm) including supply and installation. Actual Anglian quotes will vary based on home survey, window size, glazing options, and any promotions running at the time. Always get at least 3 quotes.
Ways to Reduce the Cost
Price Match Promise: Anglian will match any like-for-like uPVC window quote from a competitor within 7 days. The competitor must offer equivalent warranty and quality standards, and you’ll need a written quote on headed paper. This covers uPVC casement, tilt-and-turn, sash, flush casement, and conservatories in all colours, including double and triple glazing.
Scrappage Scheme: Anglian’s recycling programme offers an average £1,000 discount on replacement windows. The discount comes from the recycling value of your old frames – their Norwich facility sorts uPVC by colour, chips it into pellets, and uses it as a core material in new frames. Glass becomes road aggregate and metals are recycled separately.
This is NOT a government grant – it’s Anglian’s own programme funded by materials recovery. Any UK homeowner buying replacement windows qualifies.
Negotiate hard: Like all national installers, Anglian uses a commission-based sales model. Opening quotes are typically higher than the final price. Customers regularly report negotiating discounts of 20-30% from the initial figure. Never sign on the first visit, and always benchmark against our double glazing cost guide before committing.
Anglian Finance
Anglian offers credit at 11.9% APR representative (11.3% fixed annual interest rate) over 36 to 96 months. This is significantly higher than most personal loans (typically 5-7% APR from mainstream banks). For a typical £6,106 contract, monthly payments work out at £92.95 over 96 months – total payable £9,172.20, meaning you’d pay over £3,000 in interest alone.
Minimum deposits: £249 for uPVC windows and doors, £999 for timber products or living spaces. Cash orders require a 25% deposit. Anglian is FCA-authorised as a credit broker (registration 302334), not a lender – they arrange finance through third-party providers.
Important: Anglian does not offer 0% finance. Many local installers do, typically through Barclays Partner Finance. If spreading the cost matters, check whether your local FENSA-registered installer offers interest-free options before committing to Anglian’s 11.9% APR. For more on this, read our Timber Windows Guide.
Products and Window Range
Anglian offers uPVC, aluminium, and timber windows in casement, sash, bay, tilt-and-turn, flush casement, and shaped styles – all manufactured to measure at their Norwich factory.
All Anglian products are designed and manufactured in-house at the Norwich factory, giving them full supply chain control from fabrication through to installation. This is a genuine differentiator – most national installers outsource at least part of the manufacturing process.
| Window Style | Materials Available | Energy Rating | Best For |
|---|---|---|---|
| Casement | uPVC, Aluminium, Timber | A to A++ | Most homes, best value |
| Sash (Sliding) | uPVC, Timber | A rated | Period and Victorian homes |
| Flush Casement | uPVC | A to A++ | Modern flush-fit appearance |
| Bay | uPVC, Aluminium, Timber | A rated | Living rooms, kerb appeal |
| Tilt and Turn | uPVC | A rated | Easy cleaning, upper floors |
| Shaped | uPVC | Varies | Circular, triangular, arched features |
| Secondary Glazing | Aluminium frame | Varies | Listed buildings, budget option |
Triple glazing is available on uPVC flush casement and casement windows, achieving A++ energy ratings – the highest on the BFRC scale. For standard double glazing, Anglian’s uPVC windows achieve A or A+ ratings as standard, with aluminium windows rated at 1.4 W/m²K U-value.
Beyond windows, Anglian installs composite doors (from around £800–£1,500 installed), French doors, uPVC front doors, aluminium doors, conservatories (Victorian, Edwardian, lean-to, orangeries), porches, rooftrim (guttering, fascias, soffits), garage doors, and shutters. The breadth of the product range is a genuine advantage – you can get your entire exterior upgraded by a single company, which simplifies project management and warranty claims.
Customisation options include decorative and obscure glazing, leaded glass, and a range of frame colours beyond standard white. All products carry Made in Britain accreditation.
Guarantees and Warranty
Anglian provides a 10-year parts and labour guarantee on all windows and doors, insurance-backed up to £50,000 – with extended cover of 10-15 years on sealed glass units and 30 years on timber rot.
| Product | Guarantee Length | What’s Covered |
|---|---|---|
| Windows, doors, conservatory frames | 10 years | Parts and labour |
| Gas-filled sealed glass units | 10–15 years | Condensation and seal failure |
| Timber rot guarantee | 30 years | Rot (with proper maintenance) |
| Timber paint finish | 10 years | Peeling, discolouration |
| Yale 3-star cylinder locks | 10 years | + £1,000 forced-entry protection |
| Ultion 3-star locks (composite doors) | 5 years anti-snap | + £5,000 forced-entry payout |
| Garage doors | 5 years | Standard warranty |
All guarantees are insurance-backed through Home Improvement Protection (an FCA-registered Appointed Representative of Independent Warranty). The insurance covers up to £50,000 or the original installation cost, whichever is lower – meaning your guarantee remains valid even if Anglian ceases trading.
Given that Anglian’s parent company is reportedly exploring a sale, this insurance backing is more relevant than usual.
If you have a dispute, Anglian’s membership of the Glass and Glazing Federation (GGF) gives you access to their complaints service. Alternatively, FENSA can adjudicate on building regulations compliance issues. For persistent problems, Resolver.co.uk provides a structured escalation process.
Customer Reviews
Anglian scores 3.9 out of 5 on Trustpilot from 38,656 reviews – rated “Great” overall, but 18% are 1-star, indicating a polarised customer experience.
The review distribution tells a clearer story than the headline score. 60% of customers leave 5-star reviews, praising professional installation teams, product quality, and improved home comfort. But 18% leave 1-star reviews – an unusually high proportion that suggests a significant minority have genuinely poor experiences.
What customers praise most: Professional and courteous installation teams, quality of workmanship, efficient service delivery, knowledgeable sales representatives, and noticeable reduction in condensation and draughts after installation.
The most common complaints: Communication going dark after the deposit is paid, installation delays well beyond quoted timelines (8+ months reported in some cases), faulty glass and manufacturing defects on delivery, poor after-sales responsiveness, inadequate cleanup after installation, and difficulty getting warranty claims processed.
The pattern across reviews is consistent: the installation teams are generally excellent, but the company’s administrative and customer service systems let them down. If everything goes smoothly, you’ll likely be very happy. If anything goes wrong – wrong measurements, faulty glass, installation defects – getting a resolution can be genuinely difficult.
Who Owns Anglian? (What Most Sites Won’t Tell You)
Anglian is owned by ASHI Group Ltd, controlled by private equity firm Alchemy Partners – the same parent company that now owns Everest and Safestyle, making all three brands part of one group.
This is the section most comparison sites leave out entirely, but it materially affects your buying decision.
Anglian Home Improvements is owned by ASHI Group Limited, which is controlled by Alchemy Partners, a private equity firm that has held a stake since 2001. The company was taken private in 2015 when Alchemy bought back a majority stake from a consortium of banks.
In 2023-2024, Anglian acquired two of its biggest competitors out of administration:
- Safestyle UK – acquired February 2024 after administrators were appointed in October 2023
- Everest – acquired May 2024 after Everest 2020 Limited entered administration in April 2024
All three brands continue to trade separately from the Norwich headquarters, but they are controlled by the same parent company. This means that getting quotes from Anglian, Everest, and Safestyle is not the same as getting three independent quotes. If you want genuinely competitive pricing, you need to include at least one local FENSA-registered installer or a completely independent national brand like CR Smith.
Potential sale: In August 2025, trade press reported that Alchemy Partners was preparing to sell Anglian, with investment bankers appointed and a valuation of £100 million or more. Neither party has confirmed this. Industry commentary has been mixed, with some sources questioning the company’s debt burden and whether a buyer will emerge.
For consumers, the key reassurance is that the insurance-backed guarantee (via Home Improvement Protection) survives any change of ownership – your warranty is protected regardless of what happens at corporate level.
Sales Tactics and Getting the Best Deal
Anglian uses commission-based in-home sales with opening quotes typically 20-30% above the final price – always get three independent quotes and never sign on the first visit.
Anglian’s sales process follows the traditional double glazing model: a salesperson visits your home, measures your windows, and presents a quote – often during a presentation lasting 1.5 to 3 hours. The salesperson works on commission, which creates a natural incentive to close the sale on the first visit.
Common tactics reported by customers:
- “Today only” pricing – a discount presented as available only if you sign immediately. These discounts are almost always available later.
- Sequential discounting – the initial quote comes in high, then the salesperson “checks with their manager” for a better price, then offers a further discount if you commit today.
- Finance framing – presenting monthly payments (£92.95/month) rather than total cost (£9,172.20) to make the purchase seem more affordable.
How to get the best price from Anglian:
- Get at least 3 quotes from independent installers first – use our free cost calculator for a baseline
- Never sign on the first visit – our double glazing tips guide covers how to handle the sales appointment effectively. The 14-day cooling-off period exists, but getting a deposit back can be difficult in practice
- Use the Price Match Promise – bring a written quote from a competitor on headed paper within 7 days of your Anglian quote
- Ask about the scrappage scheme discount before the quote is finalised
- If paying on finance, compare Anglian’s 11.9% APR against personal loans (typically 5-7% APR) and local installers offering 0% finance
Anglian vs Everest vs Safestyle
Anglian, Everest, and Safestyle are all owned by ASHI Group – Anglian has the best reviews (3.9/5) and widest range, Everest leads on triple glazing, and Safestyle is the cheapest option.
| Feature | Anglian | Everest | Safestyle |
|---|---|---|---|
| Owner | ASHI Group (Alchemy Partners) | ASHI Group (Alchemy Partners) | ASHI Group (Alchemy Partners) |
| Trustpilot | 3.9/5 (38,656 reviews) | 2.9/5 (13,392 reviews) | 3.5/5 (48,624 reviews) |
| Frame Materials | uPVC, Aluminium, Timber | uPVC, Aluminium, Timber | uPVC only |
| Triple Glazing | Available (A++) | Standard on casement | Limited |
| uPVC Price (per window) | £250–£570 | £700–£1,800 | £150–£350 |
| Standard Guarantee | 10 years (IBG) | 10 years (IBG) | 10 years (IBG) |
| Timber Guarantee | 30 years | 30 years | N/A (no timber) |
| Price Match | Yes (7-day uPVC) | Yes (7-day) | No |
| Scrappage Discount | Yes (avg £1,000) | No | No |
| Finance APR | 11.9% | FCA-authorised | FCA-authorised |
| Manufacturing | Norwich, UK | Wales (pre-admin) | Bradford, UK |
| Covers N. Ireland | No | No | No |
| Our Rating | 7/10 | 6/10 | 5/10 |
The standout finding here is that all three brands share the same parent company. For a genuinely competitive comparison, you need at least one quote from outside the ASHI Group – either a local FENSA-registered installer or an independent national brand. Use our best double glazing companies guide for options beyond these three.
Accreditations and Standards
Anglian holds FENSA, TrustMark, GGF membership, BBA certification, ISO 9001/14001/45001, Secured by Design, FSC, and Made in Britain – one of the most accredited installers in the UK.
Anglian’s accreditation list is comprehensive and verifiable – this is one area where the company genuinely leads the market:
- FENSA – registered for replacement window and door installations (building regulations compliance)
- TrustMark – government-endorsed quality standard
- GGF – Glass and Glazing Federation member (access to complaints service)
- BBA Certified – British Board of Agrément product certification
- Secured by Design – police-backed security standard

- FSC Certified – responsible timber sourcing
- Made in Britain – all products manufactured at the Norwich factory
- Recovinyl Plus – uPVC recycling commitment
- Cyber Essentials – data security certification
Notable absence: Anglian is NOT a Which? Trusted Trader as of February 2026. Some third-party sites incorrectly claim this status – we verified directly against Anglian’s accreditations page.
Our Verdict
Strong products and accreditations, but premium pricing, 11.9% APR finance, and mixed after-sales service mean you should always get independent competing quotes

Anglian is the UK’s most accredited and largest double glazing installer, with strong products and insurance-backed guarantees – but premium pricing, 11.9% APR finance, and inconsistent after-sales service mean you should always get independent competing quotes.
Anglian is a safe choice for homeowners who value national coverage, insurance-backed guarantees, and a wide product range – and who are prepared to negotiate hard on price. But the 11.9% APR and shared ASHI Group ownership with Everest and Safestyle mean you must get at least one quote from outside the group to ensure you’re getting a fair deal.
