How Discount Variable Rates Work
Every UK mortgage lender publishes a standard variable rate (SVR). This is the rate you revert to at the end of any deal period, and it is typically 2.5-4% above the Bank of England base rate. In April 2026, with base rate at 4.50%, most lender SVRs sit between 7.00% and 8.25%.
A discount variable mortgage applies a fixed discount to this SVR. For example:
- Nationwide SVR: 7.49%
- Discount on 2-year deal: 2.00%
- Your pay rate: 5.49%
The discount size is fixed for the deal period (typically 2 or 3 years). However, the SVR itself is set by the lender and can change whenever the lender chooses. Most lenders change SVR in response to Bank of England moves, but they are under no legal obligation to pass cuts on in full or immediately. Some SVR moves are out of sync with base rate.
At the end of the discount period, you move to the full SVR (unless you remortgage).
Discount Variable vs Tracker vs Fixed
The three main variable/fixed product types work differently:
| Feature | Fixed | Tracker | Discount Variable |
|---|---|---|---|
| Rate benchmark | Set at outset | BoE base rate | Lender SVR |
| Rate changes | Never | With base rate | With lender SVR |
| Who controls the change | Nobody — it is fixed | Bank of England | The lender |
| Transparency | Very high | High (BoE published) | Lower (lender discretion) |
| Typical ERC | 1-5% | 0-3% | 0-3% |
| Typical fee | £999 — £1,999 | £999 — £1,499 | £0 — £999 |
The key practical difference: with a tracker, you know exactly what will happen to your rate if the Bank of England acts — it moves by the same amount. With a discount variable, you are dependent on the lender's decisions, which usually (but not always) mirror base rate moves.
Who Offers Discount Variable Rates?
Discount variable mortgages are primarily a building society product in the UK. Main providers:
- Nationwide — regular 2-year and 3-year discount deals
- Yorkshire Building Society — discount on SVR with competitive margins
- Coventry Building Society — known for larger discounts on longer terms
- Skipton Building Society — flexible discount products
- Leeds Building Society — niche discount deals with flexibility
- Principality — Welsh-focused, regular discount offers
- Newcastle Building Society — regional discount products
Typical discount sizes in April 2026 range from 1.50% to 2.50% off the SVR, giving pay rates of 4.99% to 5.99% at 60-75% LTV. Some lenders offer "stepped" discounts (e.g. 2.5% off for year 1, 2.0% off for year 2).
The SVR Risk Explained
The distinct risk of a discount variable is that your lender controls the SVR. In practice, most UK lenders move their SVR broadly in line with Bank of England changes, but several behaviours are worth knowing about:
- Lenders often lag rate cuts — when base rate falls, some lenders take a month or two to reduce SVR, or pass on only part of the cut
- SVRs sometimes move independently — if a lender's funding costs rise, they can raise SVR even with no base rate change
- SVR gaps widen over time — SVR minus base rate has historically drifted up. In 2015 most SVRs were around 1.5% above base rate; in 2026 many are 3%+ above
This means that even during your discount period, your effective rate relative to base rate can drift upwards if the lender widens the SVR spread. With a tracker, this cannot happen — your margin is contractually fixed.
The FCA requires lenders to give borrowers reasonable notice of SVR changes (typically 30 days), but no regulator approval is required before an SVR move.
